    Full Text Available The outcome of bicondylar tibial plateau fractures treated with either external fixation (35 patients or internal fixation (24 patients was reviewed. Outcome measures included the Rasmussen score, clinical complications, development of osteoarthritis and the requirement for total knee replacement (TKR. Twenty-two (92% anatomical reductions were achieved in the internal fixation group compared to 27 (77% in the external fixation group. Infective complications were more common in the external fixation group (9 patients, 26% due to pin tract infection. There were no deep infections in the internal fixation group. The mean Rasmussen score was not significantly different (mean score 32 in external fixation and 29 in internal fixation between the two groups and the incidence of osteoarthritis was the same in both groups. Four patients in the external fixation group underwent a TKR compared to 5 patients in the internal fixation group. Bicondylar tibial plateau fractures have similar outcomes following external or internal fixation.

    To describe the surgical treatment outcome of cervical fractures in 3 horses. Case report. Three client-owned horses with cervical vertebral fractures. Three horses were refered for neck stiffness, pain, and ataxia after a cervical trauma because of a fall. Radiographic examination showed an oblique displaced fracture of the caudal aspect of the body of the second cervical vertebra (C2) in horse 1, an oblique displaced fracture of the caudal aspect of C4 involving the disc between C4 and C5 in horse 2, and a displaced transverse fracture of the body of the axis (C2) extending to the lateral arches and involving the vertebral canal in horse 3. In horse 1, the fracture was reduced and stabilized using a 14-hole narrow DCP plate, applied ventrally, and fixed with cancellous screws. A cervical fusion was performed. In horses 2 and 3, fracture fixation was performed using a 5-hole narrow LCP and 5 mm locking screws. All horses showed improvement and returned to full activity. The fracture healed in all horses. Internal fixation of cervical fracture in these horses was associated with minimal complications, and was associated with healing and a highly functional outcome in all horses. The LCP was preferred and would be recommended for ventral stabilization of selected cases of vertebral fractures. © Copyright 2015 by The American College of Veterinary Surgeons.

    To describe internal fixation for maxillofacial fractures using titanium miniplates and report outcome in 7 dogs. Prospective case series. Skeletally mature dogs (n = 7) with maxillofacial fractures. After CT evaluation of fracture configuration, using a combination of extraoral and intraoral approaches as needed, non-locking titanium miniplates were contoured to match the normal anatomy of the fractured bones. Plates were secured using non-locking titanium screws and then covered with a soft-tissue envelope followed by routine intraoral and extraoral closure. Fractures healed rapidly after reconstruction with immediate return to normal function and occlusion. Follow-up time of up to 94 months indicated excellent long-term function and general lack of complications. One dog developed nasal aspergillosis 1.5 years after surgery and the miniplates were removed without adverse consequences. Internal fixation for maxillofacial reconstruction using titanium miniplates is an excellent solution for the treatment of comminuted and displaced maxillofacial fractures in dogs. © Copyright 2014 by The American College of Veterinary Surgeons.

    A biomechanical study assessed quantitative differences in the stability that was obtained by five commonly used types of internal fixation employed in metacarpal fractures. The techniques included dorsal plating, dorsal plating combined with an interfragmentary lag screw, crossed Kirschner wires, a single intraosseous wire combined with a single oblique Kirschner wire, and a single intraosseous wire alone. Rigidity and strength in torsion and bending were determined after transverse osteotomy and fixation of the metacarpal were performed. The failure modes for each fixation technique were also observed and described. Significant differences in rigidity were found between the plated configurations (with or without an interfragmentary lag screw) and the wired configurations in both apex dorsal bending and axial torsion. The three wired configurations were not significantly different from each other except in torsion. Analysis of the bending moments that were required to produce both yield and failure in apex dorsal bending and also the energy absorbed to yield showed similar disparity between plated and wired techniques. For metacarpal fixation, dorsal plating with or without lag screws provides significantly more stability than do wired techniques and approaches that provided by intact bones.

    Although there were many different types of fixation techniques for sacroiliac dislocation fracture, the treat remained challenging in posterior pelvic ring injury. The purpose of this study was to evaluate the biomechanical effects of a novel fixation system we designed. 12 human cadavers (L3-pelvic-femora) were used to compare biomechanical stability after reconstruction on the same specimens in four conditions: (1) intact, (2) cable system, (3) plate-pedicle screw system, and (4) cable system and plate-pedicle screw combination system (combination system). Biomechanical testing was performed on a material testing machine for evaluating the stiffness of the pelvic fixation construct in compression and torsion. The cable system and plate-pedicle screw system alone may be insufficient to resist vertical shearing and rotational loads; however the combination system for unstable sacroiliac dislocation fractures provided significantly greater stability than single plate-pedicle or cable fixation system. The novel fixation system for unstable sacroiliac dislocation fractures produced sufficient stability in axial compression and axial rotation test in type C pelvic ring injuries. It may also offer a better solution for sacroiliac dislocation fractures. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Conclusions: This case series demonstrates that an “internal fixator technique” is an acceptable alternative to the management of open fractures of the femur or tibia in adult patients. The NC-LP method provided opportunities to achieve a stable fixation with noncontact between the implant and the bone tissues, and the fractures were sufficiently stabilized to allow union with a low complication rate.

    Conventional radiographic evaluation of fracture healing is not a reliable method, because it depends on the examinator's experience and the quality of the exam. Therefore, serial images differing in density, contrast and geometrical projection can lead to a misdiagnosis on the postoperative fracture healing. Even in good quality images, little changes in calcified tissues often can't be visualized, because of its little sensibility and because of the limited human sight. The use of more sensitive and objective methods could increase the accuracy of this evaluation. This study intended to compare, by digitalized panoramic radiography, the mandible fracture healing after two different types of treatment: open reduction with internal fixation (group 1) and closed reduction with intermaxillary fixation (group 2). It was taken three postoperative radiographs (within a week, a month and three months after treatment), which were digitalized (600 dpi, 8 bits) and adjusted in brightness and size in Photoshop software. Then these images were evaluated by digital subtraction in ImageTool software. The results revealed greater areas of new bone formation in the internal fixation group, in all the evaluated times. Thus, open reduction with internal fixation resulted in more rapid fracture healing than closed reduction with intermaxillary fixation.

    Ulnar styloid fractures are often associated with distal radius fractures. However, controversy exists regarding whether to treat ulnar styloid fractures. This study aimed to evaluate clinical effects of internal fixation for ulnar styloid fractures after distal radius fractures were treated with the volar locking plate system. We used prospectively collected data of distal radius fractures. 111 patients were enrolled in this study. A matched case-control study design was used. We selected patients who underwent fixation for ulnar styloid fractures (case group). Three control patients for each patient of the case group were matched on the basis of age, sex, and fracture type of distal radius fractures from among patients who did not undergo fixation for ulnar styloid fractures (control group). The case group included 16 patients (7 men, 9 women; mean age: 52.6 years; classification of ulnar styloid fractures: center, 3; base, 11; and proximal, 2). The control group included 48 patients (15 men, 33 women; mean age: 61.1 years; classification of ulnar styloid fractures: center, 10; base, 31; and proximal, 7). For radiographic examination, the volar tilt angle, radial inclination angle, and ulnar variance length were measured, and the union of ulnar styloid fractures was judged. For clinical examination, the range of motions, grip strength, Hand20 score, and Numeric Rating Scale score were evaluated. There was little correction loss for each radiological parameter of fracture reduction, and these parameters were not significantly different between the groups. The bone-healing rate of ulnar styloid fractures was significantly higher in the case group than in the control group, but the clinical results were not significantly different. We revealed that there was no need to fix ulnar styloid fractures when distal radius fractures were treated via open reduction and internal fixation with a volar locking plate system.

    The talar neck is deviated medially with reference to the long axis of the body of the talus. In addition, it deviates plantarward. The talar neck fracture line is sometimes observed to be oriented obliquely (not perpendicular to the long axis of the talar neck). This occurs when the medially deviated talar neck strikes the horizontally oriented anterior lower tibial edge. Internal fixation of a simple displaced talar neck fracture usually requires 2 lag screws. Because the fracture line is obliquely oriented, a better method for positioning the screws perpendicular to the fracture line is to place them in a reversed direction to provide maximum interfragmentary compression at the fracture site, which could increase the likelihood of absolute stability with subsequent improvement in the incidence of fracture union and a reduction of complications, such as avascular necrosis of the body of the talus. Two lag screws are used, with the first inserted from posteriorly to anteriorly (perpendicular to the fracture line) using a medial approach after medial malleolar chevron osteotomy. The second screw is inserted from anteriorly to posteriorly (perpendicular to the fracture line) using an anterolateral approach. Both screw heads should be countersunk. A series of 8 patients underwent this form of internal fixation for talar neck fracture repair, with satisfactory functional outcomes. In conclusion, the use of antegrade-retrograde opposing lag screws is a reasonable method of internal fixation for simple displaced talar neck fractures.

  16. Operative treatment of early infection after internal fixation of limb fractures (exclusive of severe open fractures).

    Early infection after open reduction and internal fixation (ORIF) of a limb bone is defined as bacteriologically documented, deep and/or superficial surgical-site infection (SSI) diagnosed within 6months after the surgical procedure. This interval is arbitrarily considered sufficient to obtain fracture healing. The treatment of early infection after ORIF should be decided by a multidisciplinary team. The principles are the same as for revision arthroplasty. Superficial SSIs should be differentiated from deep SSIs, based on the results of bacteriological specimens collected using flawless technique. A turning point in the local microbial ecology occurs around the third or fourth week, when a biofilm develops around metallic implants. This biofilm protects the bacteria. The treatment relies on both non-operative and operative measures, which are selected based on the time to occurrence of the infection, condition of the soft tissues, and stage of bone healing. Both the surgical strategy and the antibiotic regimen should be determined during a multidisciplinary discussion. When treating superficial SSIs after ORIF, soft-tissue management is the main challenge. The treatment differs according to whether the hardware is covered or exposed. Defects in the skin and/or fascia can be managed using reliable reconstructive surgery techniques, either immediately or after a brief period of vacuum-assisted closure. In deep SSIs, deciding whether to leave or to remove the hardware is difficult. If the hardware is removed, the fracture site can be stabilised provisionally using either external fixation or a cement rod. Once infection control is achieved, several measures can be taken to stimulate bone healing before the end of the classical 6-month interval. If the hardware was removed, then internal fixation must be performed once the infection is eradicated. Copyright © 2016. Published by Elsevier Masson SAS.

    Full Text Available 【Abstract】Objective: To investigate the efficacy of the locking internal fixator (LIF, which includes the locking compression plate (LCP and the less invasive stable system (LISS, in the proximal and distal tibial fractures. Methods: We did a retrospective study on a total of 98 patients with either proximal or distal tibial fractures from January 2003 to January 2007, who had received the opera- tion with LIF by the minimally invasive plate osteosynthesis (MIPO technique. The data consisted of 43 proximal tibial fractures (type AO41C3 and 55 distal tibial fractures (type AO43C3. Results: No complications were observed in all patients after operation. The mean healing time was 8.4 months (range 5-14 months. Only two cases of delayed union occurred at postoperative 10 months. No infections were reported after the definitive surgery even in the cases of open fractures. All patients reached a full range of motion at postoperative 6 to 9 months and regained the normal functions of knee and ankle joints. Conclusion: Using LIF in MIPO technique is a reliable approach towards the proximal and distal tibial fractures that are not suitable for intramedullary nailing.

    It is uncertain whether external fixation or open reduction internal fixation (ORIF) is optimal for patients with bicondylar tibial plateau fractures. A systematic review using Ovid MEDLINE, Embase Classic, Embase, AMED, the Cochrane Library, Open Grey, Orthopaedic Proceedings, WHO International Clinical Trials Registry Platform, Current Controlled Trials, US National Institute for Health Trials Registry, and the Cochrane Central Register of Controlled Trials. The search was conducted on 3rd October 2014 and no language limits were applied. Inclusion criteria were all clinical study designs comparing external fixation with open reduction internal fixation of bicondylar tibial plateau fractures. Studies of only one treatment modality were excluded, as were those that included unicondylar tibial plateau fractures. Treatment effects from studies reporting dichotomous outcomes were summarised using odds ratios. Continuous outcomes were converted to standardized mean differences to assess the treatment effect, and inverse variance methods used to combine data. A fixed effect model was used for meta-analyses. Patients undergoing external fixation were more likely to have returned to preinjury activities by six and twelve months (P = 0.030) but not at 24 months follow-up. However, external fixation was complicated by a greater number of infections (OR 2.59, 95 % CI 1.25-5.36, P = 0.01). There were no statistically significant differences in the rates of deep infection, venous thromboembolism, compartment syndrome, or need for re-operation between the two groups. Although external fixation and ORIF are associated with different complication profiles, both are acceptable strategies for managing bicondylar tibial plateau fractures.

    To explore a new method for the treatment of ankle joint fractures, and to evaluate its therapeutic effects. Among 42 patients with ankle joint fractures, 34 patients had complete data for analysis, 19 patients were male and 15 patients were female, ranging in age from 21 to 61 years, with an average of 37 years. According to Weber-AO classification, there are 28 patients of B-type and 6 patients of C-type. The Baird and Jackson Rating System was used to evaluate therapeutic effects, and the relationship between the final function and fracture type, fracture fixation and, the time of functional training after operation were analyzed. Thirty-four patients with ankle joint fractures of B and C type were treated with internal fixation of posterior fibula plate to avoid injury of articular facet by the nails. The patients combined with the fractures of posterior malleolus were treated with fixation of both fibula and posterior malleolus through the same incision. All the patients were followed up ranging from 1.2 to 3.2 years, with an average of 1.8 years. According to evaluation criterion, 24 patients got an excellent result, 6 good and 4 fair, the excellent and good rate was 88.2%. The internal fixation of posterior fibula plate, as a treatment for ankle joint fractures, successfully avoids the injury of articular facet by the nails. Not only does it enhance the pullout strength of the nails, but it is able to treat the fracture of lateral malleolus and posterior malleolus with a single incision. It has provided a new way for the treatment of ankle fractures.

    In Oral and Maxillofacial Surgery, the majority of the condylar fractures are treated by closed reduction with generally satisfactory long term results. But in such cases of closed reduction, patient will be uncomfortable owing to long term application of inter maxillary fixation (IMF). Where as, Disadvantages of extra oral open reduction and fixation of condylar fracture includes facial nerve damage, facial scars etc. which are surely eliminated by the intraoral reduction and rigid fixation. The present study was conducted to determine the efficacy of reduction and fixation of low sub-condylar fractures through intra-oral approach. In this study, ten patients with low sub-condylar fracture, reported to department of Oral and Maxillofacial Surgery. P.M.N.M. Dental College and Hospital Bagalkot were included. These patients were treated by open reduction and internal fixation through intra-oral approach. All the patients were evaluated postoperatively for mouth opening, occlusion and mandibular deviation with regular radiographic examination for 6 weeks. All operated patients followed for 6 weeks, maximum mouth opening was more than 40 mm in seven patients (range from 40 to 50 mm) and less than 40 mm in three patients. Occlusion was satisfactory in all and none of the patients showed deviation of mandible on mouth opening. Statistical analysis showed that postoperative mouth opening was significant ('t' value = 7.88, 'P' = (0.000) value = 1.96, 'P' value (0.081), 0.05]. For occlusion standard photographs were obtained at sixth week and found minor occlusal corrections in two patients are treated by elastic traction for few days. Open reduction with internal fixation through intraoral approach has proved to be safe for early function and also effective by avoiding the patient discomfort due to long term intermaxillary fixation, psychological effect, facial nerve damage, facial scar and weight loss.

    Full Text Available We present a case of a bisphosphonate-related femur fracture in an elderly woman, who failed treatment with both cephalomedullary nail and proximal femoral locking plate, leading to successful treatment with total hip arthroplasty. Hardware failure should be included in the differential of patients with previous internal fixation of bisphosphonate-related femur fracture that present with hip or groin pain. Arthroplasty can be an acceptable salvage option in an active elderly patient with a bisphosphonate-related femur fracture.

    Full Text Available Abstract Background We have recently developed a subcutaneous anterior pelvic fixation technique (INFIX. This internal fixator permits patients to sit, roll over in bed and lie on their sides without the cumbersome external appliances or their complications. The purpose of this study was to evaluate the biomechanical stability of this novel supraacetabular pedicle screw internal fixation construct (INFIX and compare it to standard internal fixation and external fixation techniques in a single stance pelvic fracture model. Methods Nine synthetic pelves with a simulated anterior posterior compression type III injury were placed into three groups (External Fixator, INFIX and Internal Fixation. Displacement, total axial stiffness, and the stiffness at the pubic symphysis and SI joint were calculated. Displacement and stiffness were compared by ANOVA with a Bonferroni adjustment for multiple comparisons Results The mean displacement at the pubic symphysis was 20, 9 and 0.8 mm for external fixation, INFIX and internal fixation, respectively. Plate fixation was significantly stiffer than the INFIX and external Fixator (P = 0.01 at the symphysis pubis. The INFIX device was significantly stiffer than external fixation (P = 0.017 at the symphysis pubis. There was no significant difference in SI joint displacement between any of the groups. Conclusions Anterior plate fixation is stiffer than both the INFIX and external fixation in single stance pelvic fracture model. The INFIX was stiffer than external fixation for both overall axial stiffness, and stiffness at the pubic symphysis. Combined with the presumed benefit of minimizing the complications associated with external fixation, the INFIX may be a more preferable option for temporary anterior pelvic fixation in situations where external fixation may have otherwise been used.

    The purpose of this article is to evaluate the efficacy and feasibility of preoperative surgery with 3D printing-assisted internal fixation of complicated acetabular fractures. A retrospective case review was performed for the above surgical procedure. A 23-year-old man was confirmed by radiological examination to have fractures of multiple ribs, with hemopneumothorax and communicated fractures of the left acetabulum. According to the Letounel and Judet classification, T-shaped fracture involving posterior wall was diagnosed. A 3D printing pelvic model was established using CT digital imaging and communications in medicine (DICOM) data preoperatively, with which surgical procedures were simulated in preoperative surgery to confirm the sequence of the reduction and fixation as well as the position and length of the implants. Open reduction with internal fixation (ORIF) of the acetabular fracture using modified ilioinguinal and Kocher-Langenbeck approaches was performed 25 days after injury. Plates that had been pre-bent in the preoperative surgery were positioned and screws were tightened in the directions determined in the preoperative planning following satisfactory reduction. The duration of the operation was 170 min and blood loss was 900 mL. Postoperative X-rays showed that anatomical reduction of the acetabulum was achieved and the hip joint was congruous. The position and length of the implants were not different when compared with those in preoperative surgery on 3D printing models. We believe that preoperative surgery using 3D printing models is beneficial for confirming the reduction and fixation sequence, determining the reduction quality, shortening the operative time, minimizing preoperative difficulties, and predicting the prognosis for complicated fractures of acetabulam. © 2017 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    In cases where ankle fracture union has been compromised by persistent syndesmotic diastasis following open reduction internal fixation, both external rotation and shortening of the fibula have been identified as prominent features. This study reports a technique that uses a z-osteotomy to achieve both lengthening and internal rotation of the fibula to correct persistent talar shift following ankle fracture fixation. Four patients with persistent talar shift following open reduction internal fixation for an ankle fracture received z-osteotomy of the fibula to achieve both lengthening and internal rotation. At the latest clinic review, all 4 ankles exhibited satisfactory clinical and radiological union. All patients have returned to full mobility and are satisfied with the outcome. This study demonstrates the effectiveness of lengthening z-osteotomy of the fibula in correcting persistent talar shift following internal fixation of ankle fractures. Therapeutic Level V.

    To explore individual choice and therapeutic effect of distal fibula internal fixation in treating ankle fractures in elderly. From May 2012 to April 2015, 68 elderly patients with ankle fractures were treated by surgical operation, included 37 males and 31 females with an average of 69.2 years old ranging from 62 to 81 years. According to Danis-Weber classification, there were 19 cases belong to type A, 31 cases belong to type B, and 18 cases belong to type C. According to Lange-Hanson classification, 22 cases were supinatio-extorsion, 18 were pronate-extorsion, 19 were supinatio-adduction, and 9 were pronate-abduction. All patients were performed individyually with different internal fixation methods for the treatment of distal fibula fracture according to different types of fracture. Clinical results were evaluated based on clinical examination, radiographic evaluation and AOFAS score. Twelve patients were treated with Herbert screw, 7 cases with Kirschner wire tension band, 5 cases with 1/3 tube plate, 6 cases with reconstruction plate, 17 cases with fibular end dissection steel plate composite, and 21 cases with distal fibula anatomic locking plate. All patients were followed up from 12 to 26 months with an average of 17.7 months. The operative incision of all patients were primary healed. And there was no bone nonunion, ankle instability, internal fixation loosening and fracture occurred. Fracture healing time ranged from 2.7 to 4 months with an average of 3.2 months, and had significant differences among different groups( P 0.05). Dorsal stretch was 6° to 18° with an average of 15°, plantar flexion ranged from 26°to 47° with an average of 37°. AOFAS score at the latest following-up was 88.4±4.3, 34 patients got an excellent result, 30 good and 4 fair. Good clinical results could be obtained by using individualized internal fixation for distal fibula fracture for the treatment of the ankle fractures in elderly.

    Posterior pilon fractures are rare injuries and have not yet gained well recognition. The purpose of this study was to present the treatment outcome for patients with posterior pilon fractures treated with buttress plate. In this retrospective study we identified patients with posterior pilon fractures of the distal tibia who had undergone open reduction and internal fixation at our institute. Between January 2007 and December 2009, 10 patients (mean age, 46.5 years) who had undergone buttress plating via either a posterolateral approach or a dual posterolateral-posteromedial approach, were selected. All 10 patients were available for follow-up. The clinical outcome was evaluated with the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS). The radiological evaluation was performed using the osteoarthritis-score (OA-score). Satisfactory reduction and stable fixation were accomplished in all patients. At a mean follow-up of 36.2 months, all patients had good radiological results and showed satisfactory clinical recovery. The mean AOFAS sore was 87.8, the mean OA-score was 0.6, and the mean VAS scores during rest, active motion, and weight-bearing walking were 0.6, 0.8, and 1.4, respectively. Buttress plating for posterior pilon fractures gave satisfactory clinical outcomes. It also ensured rigid fixation which in turn enabled earlier postoperative mobilization.

    The treatment of dyaphiseal open fractures of the forearm follows internal or external fixation. However, the effectivity of both approaches remains controversial. The aim of this descriptive, Wais study, to assess the osteosynthesis by limited approach (internal fixation) as treatment of this type of fractures. Between 1996 and 1999, 22 patients with open dyaphiseal forearm fractures caused by gunshot and treated with this technique were analyzed. The men age was 26.8 years. There were 13 patients with type lllA and 9 patients with type lllB fractures. The mean of comminution was 6.34 mm. Additionally; the mean of quirurgical rinses was 3.7. The complications were: superficial infections, insufficient osteosynthesis and pseudoarthrosis. According to a functional scale the outcomes were, excellent good acceptable and bad. Within parenthesis are the numbers of patients. On the other hand, there were nineteen successful bone consolidations. The observed relative success of the limited approach, with 17 excellent-good cases and 79 bone consolidating, can be explained by the avoiding of unnecessary manipulation of the fractures area which promotes consolidation and reduces infection risk. Moreover the acceptable functional recovery, the absence of complications due to the technique and the restrained use of bone grafts make this technique highly performable

    Full Text Available Background: The treatment of displaced intracapsular femoral neck fracture is still an unsolved problem. Non-union and avascular necrosis are the two main complications of this fracture, especially if patient presents late. Muscle pedicle bone grafting has been advocated to provide additional blood supply. We present analysis of our 32 cases of displaced femoral neck fracture treated by internal fixation and quadratus femoris based muscle pedicle bone grafting. Materials and Methods: Open reduction and internal fixation with muscle pedicle grafting was done in 32 patients. The age of patients varied from 14-62 years (average age 45 years with male to female ratio of 13:3. Twenty-nine fractures were more than three weeks old. All the cases were treated by Meyers′ procedure. The fracture was internally fixed after open reduction and then a muscle pedicle graft was applied. It was supplemented by cancellous bone graft in seven cases. Fixation was done by parallel cancellous lag screws ( n = 19, crossed Garden′s screws ( n = 7, parallel Asnis screws ( n = 5 and Moore′s pin ( n = 1.Quadratus femoris muscle pedicle graft was used in 32 cases. In the initial 12 cases the graft was fixed with circumferential proline sutures, but later, to provide a secure fixation, the graft was fixed with a cancellous screw ( n = 20. Postoperative full weight bearing was deferred to an average of 10 weeks. Results: Union was achieved in 26/29 (89.65% cases which could be followed for an average period of 3.4 years, (2-8.5 years with good functional results and had the ability to squat and sit cross-legged. Results were based on hip rating system given by Salvatti and Wilson. The results were excellent in 15 cases, good in four cases, fair in four cases and poor in six cases. Complications were avascular necrosis ( n = 2, transient foot drop ( n = 2, coxa-vara ( n = 1 and temporary loss of scrotal sensation ( n = 1. Conclusion: Muscle pedicle bone grafting with

    The purpose of this study was to classify Galeazzi type injuries and determine the association of residual instability after rigid fixation with the fracture pattern of the shaft of the radius, using a system that is based on anatomic landmarks of the radial shaft. The clinical records of 95 patients (72 men and 23 women) with Galeazzi type injuries requiring open reduction and internal fixation of the fractures were retrospectively reviewed. The mean follow-up was 6.8 years (range, 18 mo to 11 y) after injury. Sixty-nine fractures occurred in the distal third of the radial shaft (type I), 17 fractures were in the middle third (type II), and 9 fractures were in the proximal third of the shaft of the radius (type III). Gross instability of the distal radioulnar joint (DRUJ) was determined intraoperatively by manipulation after radial fixation as compared to the uninjured side. Forty patients had DRUJ instability after internal fixation and were treated with temporary pinning with a K-wire placed transversely proximal to the sigmoid notch. Distal radioulnar joint instability after internal fixation was recorded in 37 type I fractures, 2 type II fractures, and 1 type III fracture. Distal radioulnar joint instability following radial shaft fracture fixation is significantly higher in patients with type I fractures than in patients with type II or type III fractures. The location of the radius fracture can be sufficiently used for preoperative estimation of percentage chance of potential DRUJ instability after fracture fixation.

    Full Text Available Background:Unstable Pelvic fracture,a result of high energy antero-posterior compression injury, has been managed based on internal fixation and open reduction. The mode of fixation in Unstable Pelvic fracture has, however, been a subject of controversy and some authors have proposed a need to address the issue of partial breach of the pelvic ring elements in these injuries. This study was performed to evaluate the functional and radiological results of treatment of pelvic ring fractures by open reduction, internal fixation. Methods: Thirty eight patients with unstable pelvic fractures, treated from 2002 to2008 were retrospectively reviewed. The mean age of patients’ was 37 years old (range 20 to 67. Twenty six patients were men and 12 women. The most common cause was a road traffic accident (N=37, 97%. There were 11 type-C and 27 type-B fractures according to Tile’s classification. Thirty six patients sustained additional injuries. The most prevalent additional injuries were lower extremity fractures. Open reduction, internal fixation as a definite management was applied for all patients. Quality of reduction was graded according to the grades proposed by Matta and Majeed’s score was used to assess the clinical outcome. The mean period of follow-up was 25 months (ranged from 6 to 109 months. About 81.6% of patients had either good or excellent radiological reduction. Results: The functional outcome was excellent in 66%, good in 15%, fair in 11% and poor in 7% of the patients. There were 4 postoperative infections. No sexual function problem was reported. Nerve deficits recovered completely in 2 and partially in 3 of 11 patients with preoperative neurologic deficiency. There was no significant relation between functional outcome and the site of fracture Conclusion: Unstable pelvic ring fracture injuries should be managed surgically by rigid stabilization that must be carried out as soon as the general ndition of the patient permits, and

    Fractures of the calcaneus are among the most challenging for the orthopaedic surgeon. The treatment of the intra-articular calcaneum fracture remains controversial due to complications and complexity of surgical anatomy. Treatment of calcaneal fracture ranges from non-operative treatment to operative. We present intraarticular fracture of calcaneus treated by combined percutaneous and minimal internal fixation. All cases evaluated either by X-ray or CT scan. All fractures were sanders two or three type evaluated by CT scan and either joint depression or tongue type fracture by X-ray. Lateral approach was used, posterior facet was exposed, reduced and fixed with one 4 mm canulated cancellous screws and 2 axial pins percutaneously from tuberosity. Clinical evaluation of the outcomes was done by modified Rowe Score. Out of 22 patients, 14 were male and 8 cases were female. Average age of the patients was 30.5 yrs (15-63 yrs). Mode of the injury was RTA in 6 cases and fall from height in 16 cases. There was no soft tissue problem in any patient. All fractures united without secondary displacement in an average of 8 weeks. Average duration of follow up was 26 months (6-37 months). Average Modified Rowe Score was 80 (Range 55-95). Ten patients had excellent, 10 had good and 2 had satisfactory outcome. Intra-articular fracture of the calcaneus can be well managed by minimal opening at the fracture and fixation by single cancellous screw and 2 axial k-wires, so minimizes complications and results in comparable outcomes.

    Both external fixation (ExFx) and open reduction and internal fixation(ORIF) were used to treat complex tibial plateau fractures, but it was not sure which one was better. So we did this meta-analysis to evaluate the outcomes of ExFx and ORIF in managing complex tibial plateau fractures. Articles published before August 5, 2016 were selected from PubMed, Cochrane library, and some other electronic database. Relevant journals were also searched manually with no language limited. Two independent reviewers searched and assessed the literature. A fixed effect model was initially used for meta-analyses with RevMan 5.3. When compared with ORIF, cases undergoing ExFx were more likely to return to the preinjury state at the early stage, but no difference in the later period of follow-up. However, ExFx group had higher infection rate (OR 1.98, 95% CI 1.08-3.63, P = 0.03), higher venous thromboembolism rate (OR 1.56, 95% CI 0.49-4.96, P = 0.45), higher re-operation rate (OR 0.87, 95% CI 0.47-1.62, P = 0.66) and lower compartment syndrome rate (OR 0.61, 95% CI 0.12-3.22, P = 0.56), lower TKA rate (OR 0.51, 95% CI 0.20-1.34, P = 0.17). There were no statistically significant differences in the rate of deep infection, venous thromboembolism, compartment syndrome and VTE between the two groups. Although external fixation may offer some advantages, both were acceptable strategies in managing complex tibial plateau fractures. According to our analysis results, we strongly recommend that selection of definitive fixators should base on the fracture patterns, soft-tissue condition as well as the injury stages in clinical practice. More important, further multicentered, randomized controlled studies should be implemented to get a more reliable and clear result. Copyright © 2017 IJS Publishing Group Ltd.

    This study aimed at evaluating the additional stability that is provided by anterior external and internal fixators in an unstable pelvic fracture model (OTA 61-C). An unstable pelvic fracture (OTA 61-C) was created in 27 synthetic pelves by making a 5-mm gap through the sacral foramina (posterior injury) and an ipsilateral pubic rami fracture (anterior injury). The posterior injury was fixed with either a single iliosacral (IS) screw, a single trans-iliac, trans-sacral (TS) screw, or two iliosacral screws (S1S2). Two anterior fixation techniques were utilized: external fixation (Ex-Fix) and supra-acetabular external fixation and internal fixation (In-Fix); supra-acetabular pedicle screws connected with a single subcutaneous spinal rod. The specimens were tested using a nondestructive single-leg stance model. Peak-to-peak (P2P) displacement and rotation and conditioning displacement (CD) were calculated. The Ex-Fix group failed in 83.3 % of specimens with concomitant single-level posterior fixation (Total: 15/18-7 of 9 IS fixation, 8 of 9 TS fixation), and 0 % (0/9) of specimens with concomitant two-level (S1S2) posterior fixation. All specimens with the In-Fix survived testing except for two specimens treated with In-Fix combined with IS fixation. Trans-sacral fixation had higher pubic rotation and greater sacral and pubic displacement than S1S2 (p pelvic fracture (OTA 61-C), anterior fixation with an In-Fix was biomechanically superior to an anterior Ex-Fix in the setting of single-level posterior fixation. There was no biomechanical difference between the In-Fix and Ex-Fix when each was combined with two levels of posterior sacral fixation.

    We describe a numerical experimental study of the stress generated by the internal fixation system "Dufoo" used in the treatment of vertebral fractures with the purpose of validating the numerical model of human lumbar vertebrae under the main physiological loads that the human body is exposed to in this area. The objective is to model and numerically simulate the elements of the musculoskeletal system to collect the stresses generated and other parameters that are difficult to measure experimentally in the thoracic lumbar vertebrae. We used an internal fixator "Dufoo" and vertebrae L2-L3-L4 specimens from pig and human. The system uses a total L3 corpectomy. The fixator acts as a mechanical bridge implant from L2 to L4. Numerical analysis was performed using the finite element method (FEM). For the experimental study, reflective photoelasticity and extensometry were used. Torsion and combined loads generate the main displacements and stresses in the study system, determining that the internal fixation carries out part of the function of the damaged organ structure when absorbing the stresses presented by applied loads. Numerical analysis allows great freedom in the management of the variables involved in the developed models using radiological images. Geometric models are obtained and are entered into FEM programs that allow testing using parameters that, under actual conditions, may not be easily carried out, allowing to comprehensively determine the biomechanical behavior of the coupled system of study.

    Full Text Available Microwaves are used in one method of physical therapy and can increase muscle tissue temperature which is useful for improving muscle, tendon and bone injuries. In the study, we sought to determine whether titanium alloy internal fixations influence apoptosis in tissues subjected to microwave treatments at 2,450 MHz and 40 W during the healing of fractures because this issue is not yet fully understood.In this study, titanium alloy internal fixations were used to treat 3.0-mm transverse osteotomies in the middle of New Zealand rabbits' femurs. After the operation, 30-day microwave treatments were applied to the 3.0 mm transverse osteotomies 3 days after the operation. The changes in the temperatures of the muscle tissues in front of the implants or the 3.0 mm transverse osteotomies were measured during the microwave treatments. To characterize the effects of titanium alloy internal fixations on apoptosis in the muscles after microwave treatment, we performed TUNEL assays, fluorescent real-time (quantitative PCR, western blotting analyses, reactive oxygen species (ROS detection and transmission electron microscopy examinations.The temperatures were markedly increased in the animals with the titanium alloy implants. Apoptosis in the muscle cells of the implanted group was significantly more extensive than that in the non-implanted control group at different time points. Transmission electron microscopy examinations of the skeletal muscles of the implanted groups revealed muscular mitochondrial swelling, vacuolization. ROS, Bax and Hsp70 were up-regulated, and Bcl-2 was down-regulated in the implanted group.Our results suggest that titanium alloy internal fixations caused greater muscular tissue cell apoptosis following 2,450 MHz, 40 W microwave treatments in this rabbit femur fracture models.

    Full Text Available 【Abstract】Objective: Debate continues regarding the management of calcaneal fractures, between open re- duction and internal fixation and closed treatment. Hence we aim at evaluating the radiological and functional out- comes of open reduction and internal fixation in displaced joint depression type of calcaneal fractures fixed with lock- ing calcaneal plate. Methods: In this series, 28 patients (26 unilateral and 2 bilateral with joint depression type of calcaneal fractures as per Essex-Lopresti classification system were operated on with locking calcaneal plate within 3 weeks of injury. Patients were evaluated in terms of associated injuries and X-rays of anteroposterior, lateral and axial views of the calcaneum. CT scan was done to assess the amount of com- minution and articular depression. Patients were followed up clinically and radiologically at least for 1 year. Radiologi- cal assessment was done by Bohler’s angle and Gissane’s angle along with measurement of calcaneal height and width. Functional outcome was assessed using the American Or- thopaedics Foot and Ankle Society (AOFAS scale. Results: At average follow-up of 14.5 months, average AOFAS score was 86.3 (range 66 to 97, with 86% having excellent to good results and 2 (7.7% and 1 (3.7% having fair and poor results respectively. All patients had stable ankle joint with all having dorsiflexion and plantar flexion more than 30°. Average subtalar range of motion was 17°. The mean Bohler’s angle, mean Gissane’s angle, calcaneal height and width were 25.47°, 121.3°, 4.32 cm and 3.81cm respectively at final follow-up. Three patients had flap ne- crosis at incision site and one had superficial and deep infection. Subtalar arthritis was seen in 5 patients, whereas sural nerve hypoaesthesia in 1 patient. None of the patients had compartment syndrome, heel pad problems, peroneal tendinitis, reflex sympathetic dystropy or implant failure. Conclusion: Open reduction and

    To discuss the suitable surgical approach and the internal fixation of unstable pelvic pelvic fractures. From May 2010 to May 2015, 45 patients with unstable pelvic fractures were treated with different approaches and fixations, including 38 males and 7 females with an average age of 45 years ranging from 21 to 61 years. The course was within 2 weeks. According to Young-Burg classification, 23 patients were lateral compression injuries, 6 patients were vertical shearing injuries, 16 patients were anterior-posterior compression injuries. All patients had hip pain and limitation of motion, the X-rays showed the pelvic ring fracture. All wounds healed well without complications, 45 cases were followed up for a mean period of 13 months (ranged 9 to 21 months). Patients with hip pain had a good postoperative pain relief. The post-operative X-rays showed the reduction was satisfied and the pelvic ring shaped well. According to Majeed standards, the final follow-up score was 93.5±11.6, 35 cases got excellent results, 8 were good, 2 were fare. The unstable pelvic and acetabular fractures are always with compound injury. Beside the reduction, to decrease the second surgery trauma should take into consideration as well, the intra-articular reduction and the stability of the pelvic were especially valued, so combined the different approach with minimal invasive technique can get good clinical result.

    Bone SPECT can be used after a femur neck fracture to assess the circulation of the femoral head in the immediate postoperative period because the blood supply is one of the major factors affecting bone uptake of radiotracer on bone scintigraphy. The purpose of our present study was to investigate whether osteonecrosis of the femoral head (OFH) after internal fixation of femoral neck fracture could be predicted by early and late bone SPECT. This retrospective cohort study enrolled 44 patients (33 women; mean age, 66.9 years) who underwent surgical fixation for femoral neck fractures. Early and late bone SPECT images were obtained within 2 weeks postoperatively and at 3 months postoperatively. Patients were followed up for a minimum of 24 months (average, 34 months). OFH developed in 9 out of 44 patients but no patient showed nonunion. Seventeen patients with normal femoral head uptake on early bone SPECT were healed. Of 27 patients with decreased femoral head uptake on early bone SPECT, 2 patients developed OFH on radiography before 3 months postoperatively, 18 patients recovered to normal uptake on the late SPECT, and the remaining 7 patients still showed decreased uptake on the late SPECT at 3 months postoperatively. All of these 7 cases finally developed OFH on radiography. Bone SPECT can reliably predict the possibility of OFH with after femoral neck fracture at least 3 months after surgery, while early bone SPECT showed low specificity. Clinical.

    To review postoperative complications reported after closed calcaneus fracture treated by open reduction and internal fixation (ORIF). Postoperative complications reported in the literature between 1995 and 2012 were identified. Papers were retrieved from publicly available databases and included in this study if they met the following criteria: clinical research of cases of closed calcaneus fracture treated by ORIF; ≥10 cases; detailed information about complications, treatment and follow up. Twenty-one clinical reports were analysed (2046 cases). Reported complications (and incidence rates) were: infection and skin flap necrosis (13.6%); neurovascular injury (2.8%); post-traumatic arthritis (1.2%); malreduction/implant problems (0.8%); nonunion (0.1%). Postoperative complications after closed calcaneus fracture are common clinical problems that cannot always be avoided. They can even be life altering, due to the requirement for long-term treatment or amputation and their economic impact on the patient. Complications should be diagnosed and treated promptly, to achieve satisfactory outcomes. Nonsurgical treatment (e.g. local wound care, drugs or physical therapy) can be attempted. If such measures fail, surgical treatment (e.g. debridement, skin flap transplantation, implant removal, re-opening of the reduction and internal fixation or subtalar joint arthrodesis) should be considered.

    Open reduction and internal plate fixation of the fibula is the gold standard treatment for ankle fractures. The aim of this study was to perform a prospective randomized study to compare bone union, complications and functional results of two types of internal fixation of the fibula (plating and the Epifisa FH intramedullary nail). Inclusion criteria were: closed fractures, isolated displaced fractures of the lateral malleolus, inter- and supra-tubercular bimalleolar fractures, and trimalleolar fractures. This study included 71 patients (mean age 53 ± 19): plate fixation group (n=35) and intramedullary nail fixation group (n=36). In seven cases, intramedullary nailing was technically impossible and was converted to plate fixation (the analysis of this sub-group was performed independently). Two patients died and two patients were lost to follow-up. The final comparative series included 32 cases of plate fixation and 28 cases of intramedullary nail fixation. Union, postoperative complications and Kitaoka and Olerud-Molander functional scores were analyzed after one year of follow-up. There was no significant difference in the rate of union (P=0.5605) between the two types of fixation. There were significantly fewer complications (7% versus 56%) and better functional scores (96 versus 82 for the Kitaoka score; 97 versus 83 for the Olerud-Molander score) with intramedullary nailing than with plate fixation. Intramedullary nailing of the lateral malleolus in non-comminuted ankle fractures without syndesmotic injury is a reproducible technique with very few complications that provides better functional results than plate fixation.

    To analyze the effects of three surgical operations in the treatment of Pilon fracture of Rüedi-Allgower type III, and put forward the best therapeutic method. The clinical data of 33 patients with Pilon fracture who received surgical operations (plaster immobilization group, 10 cases; distal tibia anatomical plate group, 11 cases; external fixation with limited internal fixation group, 12 cases) from October 2009 to January 2012 were analyzed. There were 5 males and 5 females, ranging in age from 24 to 61 years in the plaster immobilization group. There were 7 males and 4 females, ranging in age from 21 to 64 years in the distal tibia anatomical plate group. There were 7 males and 5 females, ranging in age from 23 to 67 years in the external fixation with limited internal fixation group. The Ankle X-ray of Pilon fracture after operation, ankle score, early and late complications were collected. Bourne system was used to evaluate ankle joint function. After 8 months to 3 years follow-up, it was found that three kinds of treatment had significant differences in the outcomes and complications (P external fixation with limited internal fixation group got the best results. The number of anatomic reduction cases in the external fixation with limited internal fixation group (7 cases) and the distal tibia anatomical plate group (8 cases) was more than the plaster immobilization group (2 cases). According to the ankle score, 8 patients got an excellent result, 3 good and 1 poor in the limited internal fixation group ,which was better than those of distal tibia anatomical plate group (5 excellent, 4 good and 2 poor) and the plaster immobilization group (3 excellent, 4 good and 3 poor).

    Our aim was to evaluate the efficacy of the treatment method using internal fixation of parallel reconstruction plates for the posterior wall of the acetabulum fractures. Randomised, prospective. Level I trauma centre. 57 patients with posterior wall fractures of the acetabulum in our department from 2007 to 2010 were treated operatively using this technique. internal fixation of two parallel reconstruction plates was used in this study. One of the plates was near the border of acetabulum. The other was parallel to the former one and was located to stress concentrated area. The clinical outcome was evaluated using the clinical grading system and radiological outcome was evaluated according to the criteria described by Matta. In addition, complications were researched in this study. The percentages of the clinical excellent-to-good and fair-to-poor results were 93.0% and 7%, respectively. We found that clinical outcome had no correlation with age, operation time from injury to operation, nor had correlation with hip dislocation, comminuted fracture condition and marginal compression fracture. Anatomical reduction was significantly correlated with excellent-to-good clinical outcome. Necrosis of the femoral head and heterotopic ossification were prone to decline the outcome of acetabular fractures despite good fracture reduction. the internal fixation of two parallel reconstruction plates facilitated rigid fixation and avoided fracture fragment injury, was an effective and reliable alternative method to treat fractures of the posterior wall of the acetabulum.

    To determine the rate of postoperative infection (POI) for internal fixation repaired equine long bone fractures and arthrodeses and identify associated risk factors. Case series. Horses (n=192) with fracture repair of the third metacarpal and metatarsal bones, radius, ulna, humerus, tibia, and femur, or arthrodesis with internal fixation. Medical records (1990-2006) were reviewed for signalment, anatomic location, fracture classification and method of repair, technique and surgical duration, bacterial species isolated, postoperative care, onset of POI, and outcome. Of 192 horses (171 [89%] closed, 21 [11%] open fractures), 157 (82%) were discharged from the hospital. Infection occurred in 53 (28% horses), of which 31 (59%) were discharged. Repairs without POI were 7.25 times more likely to be discharged from the hospital. Closed fractures were 4.23 times more likely to remain uninfected and 4.59 times more likely to be discharged from the hospital compared with open fractures. Closed reduction and internal fixation was associated with a 2.5-fold reduction in rate of POI and a 5.9 times greater chance for discharge from the hospital compared with open reduction and internal fixation. Females had a strong trend for increased POI when compared with colts and stallion but not geldings. Overall rate of POI was 28%. Fracture classification, method of repair, gender, and surgical duration were significant risk factors.

  15. The quality of life after a femoral neck fracture in elderly patients: a comparative study between internal fixation and arthroplasties

    Full Text Available Introduction: The femoral neck fracture is a frequent pathology in the elderly population, with about of 100,000 cases per year in Brazil. The surgical treatment by internal fixation or arthroplastic hip replacement is advocated today. The non-surgical treatment is reserved for cases of exception. Objective: To compare the quality of patient postoperative life treated for femoral neck fracture by two different techniques: hip arthroplasty and internal fixation. Methods: Through the SF-36 questionnaire, we study the quality of life of 60 patients with more than 65 years, treated between 2004 and 2012 in our service. Half of the patients was submitted to internal fixation and the other half to the arthroplastic replacement. Results: Higher averages in the large majority of the parameters of the questionnaire were obtained by the group which was carried out by internal fixation, but without statistical significance in most of these differences. Some international reports indicate that patients who have suffered a fracture of the femoral neck and were treated with internal fixation may recover the quality of life they had before the fracture. Paradoxically, there is a growing trend among orthopedic surgeons to perform a hip replacement surgery in these cases. Conclusion: Further studies are needed to define which is the best surgical treatment option.

    Full Text Available Aims: To evaluate the effectiveness and safety of anterior tension band wiring technique using two cannulated cancellous screws in patients with transverse (AO34-C1 or transverse with mildly comminuted (AO34-C2 patellar fractures. Materials and Methods: This is a prospective study of 25 patients with transverse fracture or transverse fracture with mildly comminuted patella fractures. All the patients were treated with open reduction and internal fixation using two parallel cannulated screws and 18G stainless steel wire as per the tension band principle. Results: There were eighteen males (72% and seven females (28%. The age group ranged from 24 to 58 years, with mean age of 38 years. The most common mode of injury was fall (72% followed by road traffic accident (20% and violent quadriceps contraction (8%. Transverse fracture was present in 60% and transverse fracture with mild comminution in 40% of patients. Mean time to achieve union was 10.7 weeks (range 8-12 weeks. Mean ROM at three months was 113.8 degree (90-130 and at final follow up this improved to 125.4 degrees (range 100-140. There was one case of knee stiffness and no case of implant failure was observed. Patients were evaluated using Bostman scoring, the mean score at three months being 26.04 which improved to 27.36 at the end of final follow up at one year. Conclusion: Cannulated cancellous screws with anterior tension band wiring is a safe, reliable and reproducible method in management of transverse patellar fractures, with less chances of implant failure and soft tissue irritation.

    Distal radius fractures are very common in medical practice. In our service, we may not have the most widely used devices for fixation of these fractures at a given moment. For this reason, we must consider all possible combinations within our power to correct them since most of the time, it is impossible to maintain a fracture reduction using a single technique. We present the case of a 24-year-old female patient treated at the Dr. Gustavo Aldereguía Lima University General Hospital in Cienf...

    Between August of 1997 and December of 2001, they were treated in the orthopedics department and traumatology of the Hospital Clinica San Rafael, 16 patients with proximal complex fractures of the tibia, using internal fixation with plate in the lateral column and an unilateral external fixer, for the medial column. It carries out a clinical and radiological pursuit with average of 27 months (minimum 4.5, maximum 40 months). In 15 patients (93,7%) it was obtained a primary consolidation and 1 case (6,2%) it presented retard in the consolidation being necessary the placement of bony implants. in 2 cases (12,5%) there was superficial infection, one in the itinerary of the nails and another in area of superficial necrosis in soft fabrics in a closed fracture. single 1 case (6,2) it presented deep infection, which, it improve with bony curettage and antibiotics. In the final radiographic evaluation, 2 cases (12,5%) they presented depression of the lateral plate; according to the functional scale of Rasmussen excellent results were obtained (27 to 30 points) in 11 cases (68,7%) and good (20 to 26 points) in 5 cases (31,2%). The radiographic results and functional global they suggest that the combination of a technique less invasive in this area criticizes, it represents a good alternative for the treatment of the proximal complex fractures of the tibia

    Full Text Available Abstract The present study is a report of retrospective case series of stress fracture of the olecranon. Six patients presented posterior elbow pain in throwing in baseball and softball, but fracture was not diagnosed in radiographs. We detected stress fracture of the olecranon using computed tomographic (CT scan and treated the patient with internal fixation with a headless cannulated double threaded screw through a small skin incision. All patients returned to competitive level without elbow complaints after the operation. When throwing athletes present with unusual posterior elbow pain and no significant findings on radiographs, a CT scan examination should be performed. We recommend surgical treatment of internal fixation with a screw through a small skin incision, as a good option for stress fracture of the olecranon in order to allow early return to sports activity in competitive athletes.

    Sacral fractures from high-impact trauma often cause instability in the pelvic ring structure. Treatment is by internal fixation which clamps the fractured edges together to promote healing. Healing could take up to 12 weeks whereby patients are bedridden to avoid hindrances to the fracture from movement or weight bearing activities. Immobility can lead to muscle degradation and longer periods of rehabilitation. The ability to determine the time at which the fracture is stable enough to allow partial weight-bearing is important to reduce hospitalisation time. This review looks into different techniques used for monitoring the fracture healing of bones which could lead to possible methods for in situ and non-invasive assessment of healing fracture in a fixated pelvis. Traditional techniques being used include radiology and CT scans but were found to be unreliable at times and very subjective in addition to being non in situ. Strain gauges have proven to be very effective for accurate assessment of fracture healing as well as stability for long bones with external fixators but may not be suitable for an internally fixated pelvis. Ultrasound provides in situ monitoring of stiffness recovery but only assesses local fracture sites close to the skin surface and has only been tested on long bones. Vibration analysis can detect non-uniform healing due to its assessment of the overall structure but may suffer from low signal-to-noise ratio due to damping. Impedance techniques have been used to assess properties of non-long bones but recent studies have only been conducted on non-biological materials and more research needs to be done before it can be applicable for monitoring healing in the fixated pelvis.

    Supramalleolar fractures are generally considered to be a difficult surgical challenge because they occur in a area where the tibia lies superficially with a precarious blood supply to the skin, exposing to the risk of infection and necrosis after internal fixation. These fractures are also situated close to the tibiotalar joint making centromedullary nailing difficult, even with distal locking. The Ilizarov external fixator could be an attractive alternative in this indication. We report a series of 17 supramalleolar fractures in 17 patients, 14 men and 3 women, treated with the Ilizarov external fixator between 1991 and 2001. Most were traffic accident victims and most had complex fractures resulting from high-energy trauma. There were many associated lesions. Fractures were open in ten patients. The Ilizarov fixator was used as the first intention treatment in seven patients and as a second line treatment in ten. The system allowed early weight bearing in all patients. Tolerance was generally good with a relatively low rate of superficial pin track infections (two cases). There was one case of osteitis which developed in a patient with an open fracture. There were no thromboembolic complications and no nerve involvement. Bone healing was achieved within three months in thirteen patients. There were three cases of late healing which were treated by the ascension technique using a cancellous graft and fibular osteotomy. The overall healing rate with this method was 94%. The one case of nonunion was successfully treated with an inter tibiofibular graft. The overall functional outcome was satisfactory in 76% of the patients, based on the Alho-Klemm criteria. Axial deformation predominated in the frontal plane: three patients had > 10 degrees varus in one case. These results could be improved by better operative technique. We advocate installing the patient in the supine position with transcalcaneal traction allowing good restitution of the leg axis. The assembly

    Intermaxillary fixation (IMF) screws were first introduced to achieve IMF as a kind of bone borne appliance for jaw fractures in 1989. Because this method can overcome many disadvantages associated with tooth borne appliance, IMF screws have been popularly used for jaw fractures since then. From March 2011 to February 2014, we treated 168 cases with single or multiple jaw fractures by open reduction and a total of 705 IMF screws were intraoperatively applied in all the cases to achieve IMF and maintain dental occlusion as an adjuvant to open reduction. The numbers, implantation sites and complications of IMF screws were retrospectively analyzed. In our experience, we found that IMF screws were important to assist open reduction of jaw fractures but their roles should be objectively assessed and the reliability of open reduction and internal rigid fixation must be emphasized. Much attention should be paid when implanting.

    To compare the biomechanic stability of distal radius fracture fixation with a new internal radiocarpal-spanning 2.4-mm locking plate, which acts as an internal distal radius fixator, versus a standard distal radius external fixator. The number of locking screws necessary for adequate fracture fixation was also assessed. Ten cadaveric specimens were mounted in a loading fixture with cables attached to the 2 flexor and 3 extensor wrist tendons. A 1-cm osteotomy was created to simulate an unstable distal radius fracture. The radiocarpal-spanning locking plate was fixed to the radius and index metacarpal with 4 screws proximally and 4 distally. The specimen was incrementally loaded through the tendons. Motion at the fracture site was determined. Screws were sequentially removed from the construct, the specimen was again incrementally loaded, and fracture motion was measured. The fixation was then changed to an external fixator, and the loading tests were repeated. Fracture fixation with the radiocarpal-spanning 2.4-mm locking plate was significantly more stable with 4 screws proximally and 4 screws distally (4 x 4) and with the 3 x 3 configuration than with the external fixator in both flexion and extension. The 4 x 4 screw configuration was not significantly different from the 3 x 3 screw configuration. The 4 x 4 screw configuration was significantly more stable than the 2 x 2 and 1 x 1 screw configurations in both flexion and extension. All internal fixator configurations and the external fixator showed more fracture displacement at increasingly higher loads. Fracture fixation with the new internal radiocarpal-spanning 2.4-mm locking plate is more stable than with a standard distal radius external fixator. Only three 2.4-mm locking screws proximally and three 2.4-mm locking screws distally are required for adequate fixation of the locking spanning plate.

    Osteonecrosis of femoral head remains a major complication of femoral neck fractures. It has been postulated that early internal fixation drastically reduces the incidence of osteonecrosis of the femoral head. However, there is a paucity of literature looking at the effect of time delay to internal fixation on the development of this late complication. In this study, we aim to assess the effect of time delay and method of internal fixation on the development of osteonecrosis in those less than 60 years of age. We retrospectively analysed 92 patients less than 60 years of age who presented with intracapsular neck of femur fractures that underwent internal fixation between 1999 and 2009. Of the 92 intracapsular fractures, 50 underwent fixation using cannulated screws, 32 using a dynamic hip screw, and ten using a dynamic hip screw with a derotation screw. In total, 13 patients (14.1 %) developed osteonecrosis of the femoral head, the highest incidence being in the cannulated screw fixation group with an osteonecrosis rate of 24 %. We did not find the time delay to internal fixation to be a significant predictor of the development of osteonecrosis. Our study demonstrated that the method of internal fixation rather than delay in internal fixation was more predictive of osteonecrosis of the femoral head. We did not find support to the current belief that early surgical fixation of neck of femur fractures reduces the risk of osteonecrosis in patients less than 60 years.

    Objective: This study aimed to compare the stability of Tile C pelvic fractures fixed with two iliosacral (IS) screws, tension band plate (TBP), and minimally invasive adjustable plate (MIAP). Methods: Six embalmed specimens of adult pelvis were used. The soft tissue was removed from the specimens, but spines from the fourth lumbar vertebra to the proximal one-third of both femurs were retained. The pubic symphysis, bilateral sacroiliac joints and ligaments, bilateral hip joints, bilateral sacrotuberous ligaments, and bilateral sacrospinous ligaments were intact. Tile C pelvic fractures were created on the specimens. The symphysis pubis was fixed with a plate, and the fracture on the posterior pelvic ring was fixed with three types of internal fixation in a randomized block design. The specimens were placed in a biomechanical machine at a standing neutral posture. A cyclic vertical load of up to 500N was applied, and displacement was recorded. Shifts in the fracture gap were measured by a grating displacement sensor. Results: Under different vertical loads, the shift in the fracture gap and displacement of the pelvic fractures fixed with two IS screws were similar to those in fractures fixed with MIAP. However, the shift in the fracture gap and displacement of fractures fixed with MIAP was significantly smaller than those of fractures fixed with TBP. Conclusion: The stability of the Tile C pelvic fractures fixed with MIAP was similar to that of fractures fixed with IS screws. MIAP performed better than TBP under vertical load. PMID:25932113

    The aim of this study was to identify risk factors for surgical site infections and to quantify the contribution of independent risk factors to the probability of developing infection after definitive fixation of tibial plateau fractures in adult patients. A retrospective analysis was performed at a level I trauma center between January 2004 and December 2010. Data were collected from a review of the patient's electronic medical records. A total of 251 consecutive patients (256 cases) were divided into two groups, those with surgical site infections and those without surgical site infections. Preoperative and perioperative variables were compared between these groups, and risk factors were determined by univariate analyses and multivariate logistic regression. Variables analyzed included age, gender, smoking history, diabetes, presence of an open fracture, presence of compartment syndrome, Schatzker classification, polytrauma status, ICU stay, time from injury to surgery, use of temporary external fixation, surgical approach, surgical fixation, operative time, and use of a drain. The overall rate of surgical site infection after ORIF of tibial plateau fractures during the 7 years of this study was 7.8% (20 of 256). The most common causative pathogens was Staphylococcus aureus (n=15, 75%). Independent predictors of surgical site infection identified by multivariate analyses were open tibial plateau fracture (odds ratio=3.9; 95% CI=1.3-11.6; p=0.015) and operative time (odds ratio=2.7; 95% CI=1.6-4.4; psite infection. Both open fracture and operative time are independent risks factors for postoperative infection.

    Full Text Available Background: Proximal humeral fractures are considered the last unsolved fractures in orthopaedics. The treatment is controversial and various operative modalities have been reported in the literature. The aim of the present study was to evaluate functional outcome and complication rate after open reduction and internal fixation of displaced proximal humerus fractures by proximal humerus AO stainless steel Tplate. Twenty-five (25 patients with displaced proximal humerus fractures treated with proximal humerus T-plate between May 2005 and June 2008 were included in the study. Fractures were classified according to the Neer classification into displaced 2-part, 3-part, and 4-part fractures. Patients were followed-up for a minimum period of two years. Functional evaluation was done according to the Neer scoring system. Scores were compared with other studies in the literature using similar implant. Twenty patients had 2-part fracture, four had 3-part fracture, and one had 4-part fracture. Eighty-eight [88% (n = 22] patients had good to excellent result, eight [8% (n = 2] had fair, and four [4% (n = 1] had poor result. Difference in Neer’s score between 2-part and 3-part fractures was not significant. Complications encountered in this series were screw backout in 8% (n = 2, superficial infection in 12% (n= 3, and avascular necrosis in 4% (n = 1 of cases. We conclude that proximal humerus AO T- plate is a cheap and easily available implant, aspects which are particularly relevant in third world countries like India. It gives reliable fixation for 2-part and 3-part fractures. Its use in more complicated fracture patterns of 4-part fractures is not recommended.

    Full Text Available Background/Aim. Distal tibial pilon fractures include extra-articular fractures of the tibial metaphysis and the more severe intra-articular tibial pilon fractures. There is no universal method for treating distal tibial pilon fractures. These fractures are treated by means of open reduction, internal fixation (ORIF and external skeletal fixation. The high rate of soft-tissue complications associated with primary ORIF of pilon fractures led to the use of external skeletal fixation, with limited internal fixation as an alternative technique for definitive management. The aim of this study was to estimate efficacy of distal tibial pilon fratures treatment using the external skeletal and minimal internal fixation method. Methods. We presented a series of 31 operated patients with tibial pilon fractures. The patients were operated on using the method of external skeletal fixation with a minimal internal fixation. According to the AO/OTA classification, 17 patients had type B fracture and 14 patients type C fractures. The rigid external skeletal fixation was transformed into a dynamic external skeletal fixation 6 weeks post-surgery. Results. This retrospective study involved 31 patients with tibial pilon fractures, average age 41.81 (from 21 to 60 years. The average follow-up was 21.86 (from 12 to 48 months. The percentage of union was 90.32%, nonunion 3.22% and malunion 6.45%. The mean to fracture union was 14 (range 12-20 weeks. There were 4 (12.19% infections around the pins of the external skeletal fixator and one (3.22% deep infections. The ankle joint arthrosis as a late complication appeared in 4 (12.90% patients. All arthroses appeared in patients who had type C fractures. The final functional results based on the AOFAS score were excellent in 51.61%, good in 32.25%, average in 12.90% and bad in 3.22% of the patients. Conclusion. External skeletal fixation and minimal internal fixation of distal tibial pilon fractures is a good method for

    To compare clinical effect of T-shaped locking internal fixation and external fixation in treating dorsal Barton's fracture,and investigate selective strategy of internal fixation. From January 2008 to January 2013, 100 patients with dorsal Barton's fracture were randomly divided into two groups. In treatment group, there were 30 males and 20 females with an average age of (33.8±3.6) years old;30 cases were type B, 20 cases were type C;and treated with T-shaped locking internal fixation. In control group, there were 32 male and 18 females with an average age of (32.9±3.4) years old; 29 cases were type B, 21 cases were type C; and treated with external fixation. Volar tilt, ulnar deviation and radial height at 3 months after operation were detected and compared between two groups. Mechara functional evaluation were used to evaluate postoperative clinical effects. Clinical cure time, postoperative complications,joint mobility and function score were recorded and compared between two groups. In treatment group,volar tilt was (11.9±2.7)°, ulnar deviation was (20.8+ 2.9)°,and radial height was (10.9±1.8) mm; while volar tilt was (9.1±1.6)°, ulnar deviation was (17.1±2.9)°, and radial height was (8.1±1.5) mm in control group. Treatment group was better than control group in volar tilt, ulnar deviation and radial height. Clinical cure time in treatment group was(12.0±2.3) weeks, shorter than control group (18.0±4.1) weeks. The incidence of complications in treatment group was lower than control group. According to Mehara functional evaluation,20 cases got excellent results, 25 good, 3 moderate and 2 poor in treatment group; 16 cases got excellent results, 14 good, 10 moderate and 10 poor in control group. Treatment group was better than control group in clinical effects.

    Fractures involving the proximal one-third of the splint bone are relatively rare and are challenging to treat. A variety of management techniques have been reported in the literature. The aim of this retrospective case series was to describe the clinical presentation and evaluate the efficacy of bioabsorbable polylactic acid screws in internal fixation of proximal fractures of the 2nd and 4th metacarpal and metatarsal bones in horses. The medical records, diagnostic images and outcome of all horses diagnosed with a proximal fracture of the splint bones and treated with partial resection and internal fixation of the proximal stump using bioabsorbable polylactic acid screws between 2014 and 2015 were reviewed. Eight horses met the inclusion criteria. The results showed that there were no complications encountered during screw placement or postoperatively. Six horses returned to full work 3 months after the operation and two horses remained mildly lame. On follow-up radiographs 12 months postoperatively (n = 2) the screws were not completely absorbed. The screws resulted in a cone-shaped radiolucency, which was progressively replaced from the outer margins by bone sclerosis. The use of bioabsorbable screws for fixation of proximal fractures of the splint bone appears to be a safe and feasible technique and may offer several advantages over the use of traditional metallic implants. © 2018 Australian Veterinary Association.

    We use a braided polyester suture in place of cerclage wire in tension band fixations. The objective of this study was to test the biomechanical properties of this technique. Sixteen cadaveric patellae were fractured and repaired by modified tension band fixation. Eight were fixed using eighteen gauge stainless steel wire as a tension band and eight using braided polyester. All specimens were subjected to tensile testing. Polyester was 75.0% as strong as wire. For dynamic testing, the patellae of seven cadaveric knees were fractured and then fixed with polyester tension bands. These were mounted in a device capable of extending the knees from 90 degrees to neutral against an applied force. None of the fixations failed. Three of the specimens fixed using 18 gauge stainless steel wire were compared with three fixed using polyester over 2000 cycles of knee flexion and extension. Polyester performed as well as wire. We conclude that polyester is an acceptable alternative to wire in tension band fixation.

    The goal of this project was to report the complications associated with mandibular angle fractures and identify variables affecting their occurrence. We retrospectively reviewed the charts of patients with a mandibular angle fracture treated at the Centre hospitalier universitaire de Québec between 2009 and 2013. Seventy-eight patients (73 males) aged 15-59 years (mean 25.2 years) met our inclusion criteria. A wisdom tooth was present in 85.9% (n = 67) of the cases and it was removed 62.7% (n = 42) of the time. Thirty-four patients (43.6%) had other mandibular fractures. Most fractures were fixated with a sagittal split osteotomy plate (n = 32; 41.0%) or a 2.0-mm plate on the lateral aspect of the mandible (n = 20; 25.6%). The overall complication rate was 42.3% (n = 33); of these 37.2% were infections, 26.9% involved plate removal and 6.4% were associated with non-union. Older patients had more infections (p = 0.03) and more plates removed (p = 0.03). When a wisdom tooth was extracted, more infections (p = 0.04) and overall complications (p = 0.02) were observed. This study confirms that, when treating a mandibular angle fracture in a healthy patient, it may be beneficial to leave a wisdom tooth in the line of fracture in place, if there is no indication to remove it.

The presence of peripheral neuropathy and the possible development of Charcot neuroarthropathy in this high risk patient population have stimulated much surgical interest to create more stable osseous constructs when open reduction of an ankle fracture/dislocation is required. The utilization of multiple syndesmotic screws (pro-syndesmotic screws to further stabilize the ankle mortise has been reported by many foot and ankle surgeons. In addition, transarticular Steinmann pins have been described as an adjunct to traditional open reduction with internal fixation (ORIF of the ankle to better stabilize the talus, thus minimizing risk of further displacement, malunion, and Charcot neuroarthropathy. The authors present a unique technique of ORIF with pro-syndesmotic screws and the application of a multi-plane circular external fixator for management of a neglected diabetic ankle fracture that prevented further deformity while allowing a weight-bearing status. This technique may be utilized for the management of complex diabetic ankle fractures that are prone to future complications and possible limb loss.

    We present the surgical technique of separate vertical wiring for displaced inferior pole fractures of the patella combined with Krachow suture and report the surgical outcomes. Between September 2007 to May 2012, 11 consecutive patients (mean age, 54.6 years) with inferior pole fractures of the patella (AO/OTA 34-A1) were retrospectively enrolled in this study. Through longitudinal incision, all patients underwent open reduction and internal fixation by separate vertical wiring combined with Krackow suture. The range of motion, loss of fixation, and Bostman score were primary outcome measures. The union time was 10 weeks after surgery on average (range: 8-12). No patient had nonunion, loss of reduction and wire breakage. There was no case of wound problem and irritation from the implant. At final follow-up, the average range of motion arc was 129.4° (range: 120-140). The mean Bostman score at last follow-up was 29.6 points (range: 28-30) and graded excellent in all cases. Separate vertical wiring combined with Krackow suture for inferior pole fractures of the patella is a useful technique that is easy to perform and can provide stable fixation with excellent results in knee function.

    This study aimed to quantitatively summarize the risk factors associated with surgical site infection after open reduction and internal fixation of tibial plateau fracture. Medline, Embase, CNKI, Wanfang database and Cochrane central database were searched for relevant original studies from database inception to October 2016. Eligible studies had to meet quality assessment criteria according to the Newcastle-Ottawa Scale, and had to evaluate the risk factors for surgical site infection after open reduction and internal fixation of tibial plateau fracture. Stata 11.0 software was used for this meta-analysis. Eight studies involving 2214 cases of tibial plateau fracture treated by open reduction and internal fixation and 219 cases of surgical site infection were included in this meta-analysis. The following parameters were identified as significant risk factors for surgical site infection after open reduction and internal fixation of tibial plateau fracture (p operative time (OR 2.15; 95% CI 1.53-3.02), tobacco use (OR 2.13; 95% CI 1.13-3.99), and external fixation (OR 2.07; 95% CI 1.05-4.09). Other factors, including male sex, were not identified as risk factors for surgical site infection. Patients with the abovementioned medical conditions are at risk of surgical site infection after open reduction and internal fixation of tibial plateau fracture. Surgeons should be cognizant of these risks and give relevant preoperative advice. Copyright © 2017. Published by Elsevier Ltd.

    The purpose of this study was to determine the outcome of unstable type C pelvic fractures treated with posterior stabilisation and the anterior subcutaneous internal fixator (ASIF). Altogether, 36 consecutive patients were treated for unstable type C pelvic ring fractures using posterior stabilisation and ASIF. After a minimum of 18 months, the clinical and radiological outcome was retrospectively investigated. Overall, three patients (8.3%) died, and 31 patients (86%) were available for follow-up after a mean of 4.5 years. Thirty of 31 patients (97%) showed radiographic bone consolidation of both the posterior and anterior pelvic ring. Only one non-union and two infections due to the anterior device were observed. The total German pelvic outcome score showed an excellent or good rating for 64.5% of the patients, and a fair or poor for 35.5%. The SF-12 questionnaire showed a significantly reduced total score for physical and mental health compared to a general reference population. The ASIF represents an innovative surgical procedure for the treatment of type C pelvic ring fractures. In the medium term, patient satisfaction was high and the complication rate was low, despite the small number of patients. More cases must be investigated before the procedure can be recommended in general, possibly replacing the external fixator for the treatment of pelvic ring fractures in the future.

  1. Open reduction and internal fixation aided by intraoperative 3-dimensional imaging improved the articular reduction in 72 displaced acetabular fractures

    Background and purpose — During acetabular fracture surgery, the acetabular roof is difficult to visualize with 2-dimensional fluoroscopic views. We assessed whether intraoperative 3-dimensional (3D) imaging can aid the surgeon to achieve better articular reduction and improve implant fixation. Patients and methods — We operated on 72 acetabular fractures using intraoperative 3D imaging and compared the operative results, duration of surgery, and complications with those for 42 consecutive acetabular fracture operations conducted using conventional fluoroscopic imaging. Postoperative reduction was evaluated on reconstructed coronal and sagittal images of the acetabulum. Results — The fracture severity and patient characteristics were similar in the 2 groups. In the 3D group, 46 of 72 patients (0.6) had a perfect result after open reduction and internal fixation, and in the control group, 17 of 42 (0.4) had a perfect result. The mean difference in postoperative articular incongruity was 0.5 mm (95% CI: 0.4–0.7). In 29 of 72 operations, the intraoperative 3D scans led to intraoperative correction of the reduction and an improved result. The duration of surgery and infection rate were similar in the 2 groups. Interpretation — Intraoperative 3D imaging, which is not time-consuming, allowed the surgeon to correct malreductions and screw placement in 29 of 72 operations, leading to better articular reduction and more precise screw placement than in operations where conventional fluoroscopic imaging was used to control the reduction.

    Full Text Available This study aimed at evaluating the medial approach for open reduction and internal fixation of Gartland type 3 displaced supracondylar fractures of humerus in children. A prospective, single centre study of on displaced supracondylar humerus fractures in 42 children was carried out at our institute. All fractures were managed with open reduction and internal fixation with crossed K-wires via medial approach. The mean follow-up was 12 months and patients were assessed according to Flynn’s criteria. No patients had post-operative ulnar nerve injury. Cubitus varus was not seen in any patient. Superficial pin tract infection occurred in three patients that subsided with anti-septic dressings and antibiotics. No deep infection occurred. 88.09 % patients showed satisfactory results as per Flynn’s criteria. The medial approach provides an excellent view of the supracondylar area. The approach is convenient due to a lower risk for ulnar nerve injury and better acceptability of the medial incisional scar.

    Full Text Available INTRODUCTION : Incidence of distal femur fractures is approximately 37 per 1 , 00,000 person - years.¹Distal femoral fractures has two different injury mechanisms, high energy trauma and low energy trauma. In high - energy trauma, the problem of restoring the function in a destroyed knee joint persists. Complex knee ligament injuries frequently occur additionally to extensive cartilage injuries. In elderly patients, extreme osteoporosis represents a particular problem for anchoring the implant. 2 Supracondylar and inter condylar fractures often are unstable and comminuted and tend to occur in the elderly or those with multiple injuries. Treatment options are many with varied results. The final outcome would depend upon the type of fracture, stabilization of fixation and and perhaps patient general condition. 3 The options for operative treatment are traditional plating techniques that require compression of the implant to the femoral shaft (blade plate, Dynamic Condylar Screw, non - locking condylar buttress plate, antegrade nailing fixation, retrograde nailing, sub muscular locked internal fixation and external fixation. 4 However, as the complexity of fractures needing treatment has changed from simple extra - articular supra - condylar types to inter - condylar and metaphyseal comminuted types, these implants may not be ideal. Double plating, and more recently, locked plating techniques have been advocated 5 . However with double plating there is often extensive soft tissue stripping on both sides of the femur, resulting in reduced blood supply and potential non - union and failure of the implants 6 . The LCP is a single beam construct where the strength of its fixation is equal to the sum of all screw - bone interfaces rather than a single screw’s axial stiffness or pullout resistance as seen in unlocked plates 7,8 . Its unique biomechanical function is based on splinting rather than compression resulting in flexible stabilization

    To assess the efficacy of postoperative continuous lumbar plexus blocks for postoperative pain control in patients undergoing open reduction and internal fixation of an acetabular fracture. Twenty-six patients who underwent open reduction and internal fixation of an acetabular fracture. DESIGN/PERSPECTIVE: According to a case-control study design, patients were divided into 2 groups: Group 1 (n = 13) received postoperatively a continuous lumbar plexus block with 0.2% ropivacaine (10 mL/hr for 48 hours), and group 2 (n = 13) received postoperatively patient-controlled analgesia with morphine (1 mg; lock-out time, 10 minutes; total 6 mg/hr). Postoperative morphine consumption, time to unassisted ambulation, and clinical and radiographic outcomes. No significant differences in demographics, surgical procedure, or duration of surgery were reported between the two groups. The lumbar plexus catheter group showed a lower requirement for morphine in the postanesthesia care unit (6 mg [0-14 mg]) and during the first 2 days (20 mg [6-55 mg] on day 1 and 29 mg [4-56 mg] on day 2) than the control group (51 mg [20-100 mg] on day 1 and 50 mg [10-93 mg] on day 2) (P = 0.001 and P = 0.021). Effective unassisted ambulation was recovered earlier in patients with the lumbar plexus catheter (3 days; range 2-4 days) than in the control group (4 days; range 3-7 days) (P = 0.015). Continuous lumbar plexus block represents an interesting alternative for postoperative pain control in patients undergoing open reduction and internal fixation of an acetabular fracture.

    Internal fixation is a popular first-line treatment method for proximal fifth metatarsal Jones fractures in athletes; however, nonunions and screw breakage can occur, in part because of nonspecific fixation hardware and poor blood supply. To report the results from 26 patients who underwent percutaneous internal fixation with a specialized screw system of a proximal fifth metatarsal Jones fracture (zones II and III) and bone marrow aspirate concentrate. Case series; Level of evidence, 4. Percutaneous internal fixation for a proximal fifth metatarsal Jones fracture (zones II and III) was performed on 26 athletic patients (mean age, 27.47 years; range, 18-47). All patients were competing at some level of sport and were assessed preoperatively and postoperatively using the Foot and Ankle Outcome Score and SF-12 outcome scores. The mean follow-up time was 20.62 months (range, 12-28). Of the 26 fractures, 17 were traditional zone II Jones fractures, and the remaining 9 were zone III proximal diaphyseal fractures. The mean Foot and Ankle Outcome Score significantly increased, from 51.15 points preoperatively (range, 14-69) to 90.91 at final follow-up (range, 71-100; P fixation of proximal fifth metatarsal Jones fractures, with a Charlotte Carolina screw and bone marrow aspirate concentrate, provides more predictable results while permitting athletes a return to sport at their previous levels of competition, with few complications.

    We report a case of pubic symphysis diastasis, which was initially asymptomatic; however, it became symptomatic with urinary incontinence during pregnancy. The patient was treated with open reduction and internal fixation of the symphysis pubis. A corticocancellous autograft was used for filling the gap which remained despite bilateral compression of the iliac bones. We obtained satisfactory outcome in terms of symptoms at the 3 years' follow-up; however, there was instability findings in the X-rays with broken screws. We conclude that asymptomatic pubic symphysis diastasis might be symptomatic after additional trauma (such as pregnancy) in the following days, if it was unstable in the very beginning of injury. Fixation of old pubic symphysis diastasis with reconstruction plate by filling the gap by using corticocancellous autograft, might not prevent ultimate implant failure if the symphysis pubis diastasis is part of an unstable pelvic fracture in the very beginning.

    We studied Y-STRUT® (Hyprevention, France), a new percutaneous internal fixation device, in combination with bone cementoplasty to prevent hip fracture. Between February 2013 and February 2015, a total of 16 femoral necks in 4 osteoporotic and 12 oncologic patients have been considered for prophylactic consolidation in this prospective multicentre pilot study involving 4 different hospitals. These consolidations were performed percutaneously under fluoroscopic guidance using Y-STRUT®, a dedicated internal fixation device. For osteoporotic patients, orthopaedic surgeons performed the prophylactic consolidations immediately after surgical treatment of a hip fracture (same anaesthesia) in the opposite side. For oncologic patients, without current hip fracture but considered at risk (Mirels score ≥8), interventional radiologists performed the procedures. We report the preliminary results of feasibility, safety and tolerance of these preventive consolidations using Y-STRUT®. Four patients (mean 83 years old) had prophylactic consolidation because of a severe osteoporosis (mean T-score -3.30) resulting in first hip fractures. Ten patients (mean 61 years old) were treated because of impending pathological fractures (mean Mirels score 9) related to femoral neck osteolytic metastases. All the procedures were performed with success. Wound healing was achieved in all cases with no access site complication. Radiographic exams performed at 3 months follow-up revealed that Y-STRUT® was well integrated in the bone. For the osteoporotic cohort, mean pain was 0.9 ± 0.7 at 3 weeks. For the oncologic cohort, it decreases from 3.6 ± 2.9 at baseline to 2.4 ± 0.9 at 2 months. Preliminary results demonstrate the feasibility and safety of Y-STRUT® implantation as well as the tolerance of the device.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate, compare and identify the surgical technique with best results for treating intra-articular calcaneal fractures, taking into account postoperative outcomes, complications and scoring in the Aofas questionnaire. METHODS: This was a retrospective study on 54 patients with fractures of the calcaneus who underwent surgery between 2002 and 2012 by means of the following techniques: (1 open reduction with extended L-shaped lateral incision and fixation with double-H plate of 3.5 mm; (2 open reduction with minimal incision lateral approach and percutaneous fixation with wires and screws; and (3 open reduction with minimal incision lateral approach and fixation with adjustable monoplanar external fixator. RESULTS: Patients treated using a lateral approach, with fixation using a plate had a mean Aofas score of 76 points; those treated through a minimal incision lateral approach with screw and wire fixation had a mean score of 71 points; and those treated through a minimal incision lateral approach with an external fixator had a mean score of 75 points. The three surgical techniques were shown to be effective for treating intra-articular calcaneal fractures, without any evidence that any of the techniques being superior. CONCLUSION: Intra-articular calcaneal fractures are complex and their treatment should be individualized based on patient characteristics, type of fracture and the surgeon's experience with the surgical technique chosen.

    Full Text Available Background: Ununited femoral neck fracture is seen commonly in developing countries due to delayed presentation or failure of primary internal fixation. Such fractures, commonly present with partial or total absorption of femoral neck, osteonecrosis of femoral head in 8-30% cases with upward migration of trochanter posing problem for osteosynthesis, especially in younger individuals. Several techniques for treatment of such conditions are described like osteotomies or nonvascularied cortical or cancellous bone grafting provided varying degrees of success in terms of fracture union but unsatisfactory long term results occurred due to varying incidence of avascular necrosis (AVN of femoral head. Moreover, in presence of AVN of femoral head neither free fibular graft nor cancellous bone graft is satisfactory. The vascularied bone grafting by deep circumflex iliac artery based on iliac crest bone grafting, free vascularied fibular grafting and muscle pedicle periosteal grafting showed high incidence of success rate. Osteosynthesis is the preferred treatment of choice in ununited femoral neck fracture in younger individuals. Materials and Methods: Of the 293 patients operated during the period from June 1977 to June 2009, 42 were lost to followup. Seven patients with gluteus medius muscle pedicle bone grafting (MPBG were excluded. Thus, out of 244 patients, 208 (85.3% untreated nonunion and 36 (14.7% following failure of primary internal fixation were available for studies. Time interval between the date of injury and operation in untreated nonunion cases was mean 6.5 months and in failed internal fixation cases was mean 11.2 months. Ages of the patients varied from 16 to 55 years. Seventy patients had partial and 174 had subtotal absorption of the femoral neck. Evidence of avascular necrosis (AVN femoral head was found histologically in 135 (54.3% and radiologically in 48 (19.7% patients. The patients were operated by open reduction of fracture

    Treatment of mandibular fractures by open reduction and internal fixation (ORIF) is often assumed to be superior to treatment by close reduction and maxillomandibular fixation (MMF) because patients managed by ORIF seem to be rehabilitated earlier according to functional and social aspects. This assumption is often from surgeon's perspective, not taking into account patient's view point. This study highlights a comparative assessment between ORIF and MMF from the patients' perspective. Fifty six patients with mandibular fractures within the tooth bearing areas of the mandible were prospectively studied in a randomized controlled pattern for postoperative Quality of Life (QoL) after ORIF versus MMF. Both groups were analyzed preoperatively, at 1 day, 6 and 8 weeks regarding their QoL using the General Oral Health Assessment Index questionnaire (GOHAI). No significant statistical difference was found between the groups regarding overall QoL. Patients managed by MMF were more affected by psychosocial and physical domains whereas patients managed by ORIF were more affected by the pain domain. The results demonstrate that the treatment affects the psychosocial, physical and pain domain differentially. When both treatments are possible the patient's should be enlightened on the advantages and disadvantages of both treatment modalities to guide their choice of treatment.

    Full Text Available BACKGROUND There are always difference of opinion in the importance of Bohler’s angle in evaluating the severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following surgical fixation. The purpose of this research, the relationship exists between Bohler’s angle and the injury severity of displaced calcaneal fractures and between surgical improvement of Bohler’s angle and its practical outcome. MATERIALS AND METHODS Patients were treated surgically for unilateral closed displaced intra-articular calcaneal fractures from May 2014 to October 2016 were identified. The Bohler’s angles of bilateral calcaneus were measured and was compared to the dimension of the uninjured foot was used as its normal control. The difference in the value of Bohler’s angle measured preoperatively or after surgery between the angle of the damaged foot and that of the contralateral calcaneus was calculated, respectively. The change in Bohler’s angle by ratio was calculated by dividing the variation in the value of Bohler’s angle between bilateral calcaneus by its typical control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot and Ankle Society hindfoot scores. RESULTS 30 patients were included into the study with a mean follow-up duration of 30 months. According to Sanders classification, the fracture pattern included 12 type II, 10 type III and 8 type IV fractures. According to American Orthopaedic Foot and Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 10, 8, 4 and 2 patients, respectively. The preoperative Bohler’s angle, difference value of Bohler’s angle between bilateral calcaneus and change in Bohler’s angle by ratio each has a significant relationship with Sanders classification (P=0.003; P=0.004; P=0.005, respectively, however, is not correlated with

    The healing process of spiral fractures of the sheep tibia was investigated in an experiment with simulated clinical conditions. The effects of conventional internal fixation techniques with the DCP and the intramedullary nail are compared with those of internal fixation with the spine fixator. The internal fixation techniques are described in terms of their bending stiffness when mounted on the fractured bone. The in vivo investigation was documented clinically and radiographically and the post mortem specimens were evaluated histologically. The bending stiffness of the healed bone was assessed in relation to the contralateral side. After application of the DCP, primary healing took place and extensive transcortical necrosis occurred in the implant bed. Intramedullary nailing led to secondary healing and to necrosis of the inner cortex close to the endosteum. After internal fixation with the spine fixator, gap healing took place and no cortical necrosis was observed. The clinical course was generally good after all procedures. The histological evaluation shows that damage to the vascularity of the bone can only be avoided by using the spine fixator. This principle seems to be appropriate for the purposes of biological internal fixation.

  14. Pitfalls associated with open reduction and internal fixation of fractured ribs.

    Sarani, Babak; Schulte, Leah; Diaz, Jose J

    2015-12-01

    Rib fracture is exceedingly common and remains a leading cause of death in patients with chest injury. Probability of death increases by 19% with each broken rib, and the probability of death increases further with age. Treatment is centered on pain control and early mobilization to provide adequate pulmonary hygiene. Multimodality interventions, such as incentive spirometry, postural changes, and coughing, are pivotal in minimizing the risk of pneumonia and death. Recently, many studies have found mortality benefit to operation fixation (ORIF) of ribs in select patients. However, this procedure remains underutilized partly due to lack of familiarity with its technique and pitfalls by trauma surgeons, in particular. Whereas there are publications on operative technique, there are no studies describing pitfalls associated with this procedure. The purpose of this paper is to describe pitfalls on the technical aspects of ORIF of the ribs based on the medical literature where possible and based on our experience in instances where peer reviewed evidence is lacking. The paper is not meant to serve as a protocol for managing rib fractures. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To retrospectively evaluated Gamma nail internal fixation in the treatment of elderly patients with post-stroke hemiplegia experiencing trochanteric hip fracture. The patients were obtained consecutively from January 2005 to December 2010 with inclusion criteria. The total number was 138 and allocated to two groups: treated with the Gamma nail (n=72,group A) and continuous skin traction (n=66,group B). Preoperative variables including patient age, gender, duration of cerebrovascular accident, duration of hypertension, ASA risk score, Harris hip score and fracture type were recorded and compared. After treatment, time of patients activity on the bed, ambulation time, Harris hip score, mortality, complications were recorded and used to compare the outcomes. (1) Follow-up was undertaken from 3 to 10 years, with an average of 5.8 years. (2) No statistical difference in preoperative variables was found between the 2 groups. (3) two groups had statistical significance (P=0.000) in the time of patients activity on the bed and ambulation time and group A can activities on the bed and ambulates earlier. (4) There were significant differences between 2 groups in Harris hip score at 1 and 3 years and group A was significantly higher than group B. (5) there were statistically significant differences in mortality of 3 years, 5 years and 10 years and the group B was significantly higher than the group A. (6) There was a statistical significance in complications between 2 groups and group B was higher than group A. Major complications in group A were pain, lag screw cut out, implant infection and distal femoral fractures caused by fall after the surgery. On elderly patients with trochanteric hip fracture on the hemiplegic lower side, Gamma nail internal fixation treatment can achieve better effect, patients can be early activity, fewer complications, and less mortality.

    External fixation combined with limited open reduction and internal fixation (EF + LORIF) is a well-accepted and effective method for distal tibia shaft fractures, but it was also related to complications. The objective of this study was to compare external fixation combined with closed reduction and internal fixation (EF + CRIF) with EF + LORIF in the treatment of distal tibia shaft fractures, and explore the benefits and defects of these two techniques. Fifty-six patients were randomised to operative stabilisation either by an external fixator combined with two closed titanium elastic nails or by external fixation combined with limited open reduction and internal fixation. Pre-operative variables included the patients’ age, sex, the affected side, cause of injury, Tscherne classification of soft tissue injury, fracture pattern, and time from injury to surgery. Peri-operative variables were the operating time and the radiation time. Postoperative variables were wound problems and other complications, union time, time of recovery to work, the functional American Orthopaedic Foot and Ankle surgery (AOFAS) score. There was no significant difference in the mean operating time (72.6 ± 11.5 vs. 78.5 ± 16.4 min, P = 0.125), the time to union (21.2 ± 11.0 vs. 22.5 ± 12.3 weeks, P = 0.678), the time of recovery to work (25.0 ± 14.5 vs. 26.4 ± 13.6 weeks, P = 0.711), pin track infection (3/28 vs. 4/28, P = 1.000), delayed union (2/28 vs. 3/28, P = 1.000), pain (38.3 ± 1.6 vs. 38.7 ± 1.5, P = 0.339), function (44.4 ± 6.0 vs. 45.0 ± 5.5, P = 0.698), and total AOFAS scores (91.5 ± 7.4 vs. 93.4 ± 6.8, P = 0.322) between the two groups. However, the mean radiation time was longer in the EF + CRIF group than in the EF + LORIF group (2.0 ± 1.2 vs. 0.3 ± 0.1 min, P alignment was obtained in 50 patients (22 in EF + CRIF vs. 28 in EF + LORIF, P = 0.023). Two cases with EF + CRIF had a 6 degrees of recurvatum deformity and four had 6–9 degrees of valgus deformity

    Full Text Available Background: Proximal humeral fractures are among common types of fractures and remain a challenging issue for surgical management. This study aimed to assess the clinical outcomes and complication rates of three- vs. four-part proximal humeral fractures, treated with internal fixation using the Philos® plate. Material and Methods: In this cohort study, a total of 30 consecutive patients with three-part or four-part proximal humeral fractures based on the Neer classification were included. Surgical treatment was performed with open reduction and internal fixation using the Philos® plate. The constant score was evaluated 6 months later in follow-up. The P<0.05 was considered significant. Results: Four-part fractures were mainly caused by trauma from above, while insults of opposite direction were responsible for more than half of 3 part fractures (P=0.01. Open fractures were only observed in patients with a four-part fracture (P=0.018. No significant differences were noticed regarding gender, cause, and side of the fracture. The presence of other fractures, fracture of the implant, reduction loss, avascular necrosis (AVN of humerus head, rotator cuff injury, and revision surgery were significantly higher in patients with four-part fractures. The mean constant score was 81.40±11.61 and 65.09±16.09 for three-part and four-part fractures, respectively (P=0.006. Conclusion: Open reduction and internal fixation with Philos® plate yield acceptable results in both types of fractures, however, the prognosis of this intervention is poorer four-part fractures.

    We hypothesized that internal fixation procedures performed on trauma intensive care unit (ICU) patients with systemic infections, some also febrile, would be at increased risk for deep infection. A total of 128 patients (mean age, 37.4 years; mean Injury Severity Score [ISS], 34.7) admitted to the ICU with 179 femur or tibia fractures developed systemic infections. Systemic infections included sepsis, pneumonia, urinary tract infections, abdominal infections, and wound infections remote to the fracture. Of the fractures, 33 open and 146 closed underwent 150 intramedullary and 29 plate fixation procedures. Data were gathered regarding antibiotic use, systemic infection timing in relation to the date of fixation, and whether fever (>38.2°C) was present within 24 hours of fixation. Patients were followed up for a mean of 491 days. Twenty-eight procedures were performed a mean of 4.7 days after the diagnosis of a systemic infection, and 151 were performed a mean of 9.3 days before the diagnosis. Forty-five procedures were performed in patients who were febrile within 24 hours. Of the 179 procedures, 10 (5.6%) developed a deep infection. Four patients' implant infection was potentially hematogenously seeded with the same organism as their systemic infection. Neither the timing of the systemic infection in relation to the fixation procedure nor the presence of fever within 24 hours of fixation, days of preoperative antibiotics, location of the fracture, type of fixation (intramedullary nail vs. plate fixation), or type of systemic infection was significantly associated with the development of an infection. The only significant risk factor for developing an orthopedic infection was an open fracture (p close conjunction to the diagnosis of systemic infection led to a 5.6% infection rate, which compares favorably with historic infection rates for fixation of open or closed tibia and femur fractures.

    Full Text Available In developing countries, due to limited availability of modern anesthesia and overcrowding of the hospitals with patients who need surgery, high-risk patients with “intertro-chanteric” fractures remain unsuitable for open reduction and internal fixation. The aim of this study was to analyze the results of external fixation of “intertro-chanteric” fractures in high-risk geriatric patients in a developing country. The results of 62 ambulatory high-risk geriatric patients with a mean age of 70 years (range 58-90 years with “intertrochanteric” fractures, in whom external fixation was performed, are reported. Eight patients died during follow-up due to medical causes unrelated to the surgical procedure. So only 54 patients were available for final assessment. Procedure is simple, performed under local anesthesia, requires less time for surgery and is associated with less blood loss. Good fixation and early ambulation was achieved in most of the patients. Average time to union was 14 weeks. Thirty-one patients developed superficial pin tract infection and 28 patients had average shortening of 15 mm due to impaction and varus angulation. Functional outcome was assessed using Judet’s point system. Good to excellent results were achieved in 44 patients. This study demonstrated that external fixation of “intertrochantric” fractures performed under local anesthesia offers significant advantage in ambulatory high-risk geriatric patients especially in a developing country.

  20. Open reduction and internal fixation of displaced intraarticular fractures of the calcaneus - influence of type of fracture and congruency of the subtalar joint upon functional result

    Full Text Available Background: More and more, open reduction and internal fixation (ORIF followed by early motion are advocated for displaced intraarticular fractures of the calcaneus. In prospective study the author asked, what are the results of ORIF with the calcaneal plate in intraarticular fractures of the calcaneus, and whether type of fracture and/or congruity in the subtalar joint influence these results.Methods: Forty-three intraarticular fractures of the calcaneus (30 Type II, 10 Type III and 3 Type IV according to Sanders classification were operated through extensile lateral approach. After reduction of the subtalar joint and restoration of the calcaneus shape, the fracture was fixed with the calcaneal plate. Mostly, surgery was delayed for a few days until soft tissues recuperate. Motion of the ankle and the subtalar joint was encouraged immediately, partial weight bearing after 6–8 weeks and full weight bearing after 3–4 month. After surgery, subtalar joint was found congruent in 33 (77% and non-congruent (within 2 mm in ten fractures.Results: Functional results of 36 fractures with a representative type distribution were evaluated 12 to 61 months postinjury. Functional results were satisfactory in 31 fractures (86% and not satisfactory in five (14%. All fractures with unsatisfactory results were comminutive (Type III or IV. Four fractures with congruent joint had unsatisfactory, and eight of nine fractures with uncongruent joint had satisfactory result. Statistically, functional results of the comminuted fractures were significantly worse. However, functional results of fractures with non-congruent joint were comparable to the results of fractures with congruent joint and analysis of variance showed that interaction of these two factors was not important.Conclusions: This prospective study confirms that ORIF enables satisfactory results in majority of displaced intraarticular fractures of the calcaneus. It also confirms that comminution in the

    Internal fixation of bone fractures using biodegradable poly(L-lactic-acid) (PLLA)-based materials has attracted the attention of many researchers. In the present study, 36 male beagle dogs were randomly assigned to two groups: PLLA/PLLA-gHA (PLLA-grafted hydroxyapatite) group and PLLA group. PLLA/PLLA-gHA and PLLA plates were embedded in the muscular bags of the erector spinae and also implanted to fix mandibular bone fractures in respective groups. At 1, 2, 3, 6, 9, and 12 months postoperatively, the PLLA/PLLA-gHA and PLLA plates were evaluated by adsorption and degradation tests, and the mandibles were examined through radiographic analysis, biomechanical testing, and histological analysis. The PLLA/PLLA-gHA plates were non-transparent and showed a creamy white color, and the PLLA plates were transparent and faint yellow in color. At all time points following surgery, adsorption and degradation of the PLLA/PLLA-gHA plates were significantly less than those of the PLLA plates, and the lateral and longitudinal bending strengths of the surgically treated mandibles of the beagle dogs in the PLLA/PLLA-gHA group were significantly greater than those of the PLLA group and reached almost the value of intact mandibles at 12 months postoperatively. Additionally, relatively rapid bone healing was observed in the PLLA/PLLA-gHA group with the formation of new lamellar bone tissues at 12 months after the surgery. The PLLA/PLLA-gHA nano-composite can be employed as a biodegradable material for internal fixation of mandibular bone fractures.

    For talar neck fractures, open reduction and internal fixation have been thought to facilitate revascularization and prevent osteonecrosis. Newer screw systems allow for placement of cannulated headless screws, which provide compression by virtue of a variable pitch thread. The present study compared the biomechanical fixation strength of cannulated headless variable-pitch screw fixation and locking plate fixation. A reproducible talar neck fracture was created in 14 fresh cadaver talar necks. Talar head fixation was then performed using 2 cannulated headless variable-pitch 4-mm/5-mm diameter (4/5) screws (Acutrak; Acumed, Hillsboro, OR) and locking plate fixation. Headless variable-pitch screw fixation had lower failure displacement than did locking plate fixation. No statistically significant differences were found in failure stiffness, yield stiffness (p = .655), yield load (p = .142), or ultimate load between the 2 fixation techniques. Cannulated headless variable-pitch screw fixation resulted in better failure displacement than locking plate fixation in a cadaveric talus model and could be considered a viable option for talus fracture fixation. Headless, fully threaded, variable-pitch screw fixation has inherent advantages compared with locking plate fixation, because it might cause less damage to the articular surface and can compress the fracture for improved reduction. Additionally, plate fixation can increase the risk of avascular necrosis owing to the wider incision and dissection of soft tissues. Copyright © 2015 American College of Foot and Ankle Surgeons.

    This study compares the outcomes of calcaneal fracture surgery after open reduction internal fixation and plating (ORIF) versus arthroscopic assisted percutaneous screw fixation (APSF). Group I (N=12) underwent ORIF. Group II (N=15) underwent APSF. Anthropometric data, pre and post-operative stay, complications and duration off work were recorded in this retrospective case cohort study. Radiographs were analyzed for Bohler's, Gissane's angle and Sanders' classification. AOFAS Hindfoot and SF 36 scores were collected at final follow-up. Anthropometric data, Bohler's and Gissane's angles, AOFAS and SF 36 scores were not significantly different. Pre-operative duration was 12.3 days in ORIF and 6.9 days in APSF. Post-operative duration was 7.3 days vs 3.8 days. Duration off work was 6.2 months vs 2.9 months. The APSF group was able to have surgery earlier, go home faster, and return to work earlier. This study was not powered to demonstrate a difference in wound complication rates. Copyright © 2015 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.

    The study's purpose was to answer the following clinical question: in patients with mandibular angle fractures requiring open reduction and internal fixation, do those who have fixation screws inserted using a transbuccal approach compared with those with fixation screws inserted using a transoral approach have fewer complications after treatment? The investigators hypothesized that the transoral approach was associated with a higher risk of complications. A multicenter retrospective cohort study was performed in patients who had open reduction and internal fixation of mandibular angle fractures from 2008 to 2010 within Western Australia. Patients were divided into transbuccal and transoral groups and then further subdivided into groups with and without fixation failures (primary outcome variable) and statistically compared. Binary logistic regression was used to control for possible confounders, which included patient gender, age, a wisdom tooth within the fracture not extracted, dental caries, partial dentition, bilateral/unilateral fractures, and smoking. In total 597 patients were in the study. Sixteen percent of patients in the transoral group had complications after treatment versus 10% in the transbuccal group. For the transoral technique, the odds of having fixation failure was 1.71 times greater than with the transbuccal technique (95% confidence interval, 1.02 to 2.93; P = .04). Incidences of all complication variables (hardware loosening/fracturing, wound dehiscence, secondary infection, surgery redo, nonunion/malunion of fracture, and removal of plate) were lower in the transbuccal group apart from plate fracture. The transbuccal technique was associated with fewer complications after treatment compared with the transoral technique. Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.

    PurposeTo compare the efficacy of percutaneous cementoplasty (PCP) with and without interventional internal fixation (IIF) on malignant impending pathological fracture of proximal femur.MethodsA total of 40 patients with malignant impending pathological fracture of proximal femur were selected for PCP and IIF (n = 19, group A) or PCP alone (n = 21, group B) in this non-randomized prospective study. Bone puncture needles were inserted into the proximal femur, followed by sequential installation of the modified trocar inner needles through the puncture needle sheath. Then, 15–45 ml cement was injected into the femur lesion.ResultsThe overall excellent and good pain relief rate during follow-ups were significantly higher in group A than that in group B (89 vs. 57 %, P = 0.034). The average change of VAS, ODI, KPS, and EFES in group A were significantly higher than those in group B at 1-, 3-, 6-month, 1-year (P < 0.05). Meanwhile, The stability of the treated femur was significantly higher in group A than that in group B (P < 0.05).ConclusionPCP and IIF were not only a safe and effective procedure, but resulted in greater pain relief, bone consolidation, and also reduced the risk of fracture than the currently recommended approach of PCP done on malignant proximal femoral tumor.

    We conducted a regional 2-stage prospective audit involving 5 different maxillofacial units in the Yorkshire region of the UK to evaluate the effectiveness of perioperative antimicrobial prophylaxis in the treatment of mandibular fractures. In the first stage (145 patients) we surveyed current practice concerning antimicrobial prophylaxis and found out the current infection rate after open reduction and internal fixation (ORIF) of mandibular fractures. In the second stage (157 patients) we implemented a common antimicrobial protocol in all units and recorded the infection rates using the new regimen. In the first stage a wide range of antimicrobial prophylaxis was used in different units. The agreed perioperative antimicrobial protocol in the second stage was to begin amoxicillin or clarithromycin and metronidazole intravenously on admission and include 2 postoperative doses. The infection rates were 10.3% and 8.9%, respectively, and the difference between the two groups was not significant (χ(2)=0.051, df=1, p=0.83). The infection rate in the Yorkshire region was similar to results from other centres. We recommend short perioperative antimicrobial prophylaxis with a maximum of 2 postoperative doses after ORIF of mandibular fractures.

    Full Text Available BACKGROUND In the supra and intercondylar fractures of femur particularly with intra articular extension, patient may develop stiffness of knee, shortening, rotational deformities, internal derangement of knee with instability, varus and valgus deformities which affect patient’s routine lifestyle. If these cases were treated with locking compression plate, the results obtained were successful, superior, timesaving providing early ambulation and least disability improving the functional outcome. MATERIALS AND METHODS This is a prospective interventional study. This study includes 25 supracondylar and intercondylar fractures of femur (both Muller’s Type ‘A’, Type B and Type ‘C’ fractures treated with open reduction and internal fixation by Locking Compression Plate in the Department of Orthopaedics, King George Hospital, Visakhapatnam from September 2013 to September 2015. There are 16 males and 9 females with age ranging from 20 to 80 years with an average of 44.6 years. Average age for males is 28.9 years and average age for females is 25 years. 18 fractures were due to road traffic accidents and 6 cases are due to fall from significant heights, 1 case due to simple fall from standing (osteoporosis. 15 cases were in right femur (60% and 10 cases were in left femur (40%. RESULTS 25 cases were included in the study. There is an increase in the rate of union, decreased time taken for union, increased knee range of motion, decreased time for weight-bearing, postoperative complications and duration for hospital stay. CONCLUSION LCP proved to be a good implant which could take the challenges like poor bone stock, severe comminution both metaphyseal and articular and prove successful. The locking head screws distally have prevented varus collapse, even in cases of osteoporosis. The Condylar LCP can be used in either an open or a minimally invasive manner.

    Full Text Available Background: In this study, functional state of patients with Type C distal humerus fractures undergone surgical plating was evaluated 6 and 12 months after the surgery in order to record postsurgical factors such as pain level and job/performance satisfaction. Materials and Methods: In this cross-sectional study, 46 patients with humerus fractures were recruited and their ability to do daily tasks, presence of degenerative changes, stability of elbow joint, and range of motion was evaluated. For assessment of response to surgery, Mayo score was used. Results: Among 46 patients, 45 (97.8% of them had joint stability. Evaluation of postsurgical complications showed that six subjects (13% had no complications, but superficial infection was observed in 12 (26.1% subjects. Neuromuscular disorders in ulnar nerve were present in 11 subjects (23.9%, recurrent articular bursitis of elbow joint in 6 subjects (13%, stiffness of elbow joint in 29 subjects (63%, nonunion of fracture in 3 subjects (6.5%, and myositis ossification in 4 (8.7% subjects. Furthermore, 18 (39.1% patients presented with more than one (2–4 complications. Conclusion: Open reduction and internal fixation surgery with dual plating is the method of choice for treatment of Type C distal humeral fractures. Evaluation of long-term outcomes of this surgery could be done via several different questionnaires as many studies suggest. This study demonstrated that the outcomes of this surgery in Isfahan, Iran, have been noticeably inferior compared to results of the studies in other parts of the world.

    We developed a hinged external fixator for the treatment of dislocated intra-articular calcaneus fractures with severe soft tissue damage. The external fixation was performed with a known external fixator system. The screw insertion points were biomechanically tested by defining a virtual rotation axis through the center of the talus to allow early active motion in the ankle joint. Long-term follow-up was performed after an average of 7.3 years. Results were graded with the American Orthopaedic Foot and Ankle Society (AOFAS) score. Radiographs were reviewed according to Sanders classification. Four open fractures and 33 cases with extremely swollen soft tissue, blisters, or compartment syndromes were treated. In 24 cases (64.9%), the hinged fixator was the final method of treatment (group I). A change to open reduction with internal fixation was performed in 13 fractures (35.1%) when soft tissue problems were minimal (group II). There were no late amputations, osteomyelitis, or malunions. According to Sanders classification, group I consisted of 14 type II, 8 type III, and 2 type IV fractures. Pin loosening or pin infection was seen in 4 cases, but there was no redislocation. The Böhler's angle improved in 43%, gaps in the posterior facet were closed in 41%, and any shortening or deviation of the axis was corrected in 82% of the cases. The AOFAS score for the group averaged 66.5. According to Sanders classification, group II consisted of 8 type II and 5 type III fractures. The Böhler's angle improved in 88%, and gaps in the posterior facet were closed in 87%. Any shortening or deviation of the axis was corrected in 95%, and the AOFAS score averaged 61.3. Significant differences in patient outcome scores between open reduction with internal fixation and hinged fixator were not found. P value was > .05. The hinged external fixator frame can be used in all calcaneus fracture types without soft tissue limitation. The hinged fixator allows early movement in the ankle

    As one-third of the tibial surface is subcutaneous throughout its length, open fractures are commonly encountered in this bone. The factors which determine the outcome of these fractures are severity of the injury, indicated by the degree of initial displacement, comminution and soft tissue injury and the damage to the tibial blood supply. In open fractures not only is the endosteal circulation disrupted but also the periosteal circulation, because of periosteal stripping. The va...

Between January 2009 and April 2012, 12 patients with open Tile C pelvic fractures were treated. There were 7 males and 5 females, aged 6-53 years (median, 31 years). Of 12 cases, 4 were classified as Tile type C1, 6 as Tile type C2, and 2 as Tile type C3; 5 were rated as Gustilo type II and 7 as Gustilo type III. The injury severity score was 18-57 (mean, 37.2). The interval of injury and admission ranged from 15 minutes to 3 days (median, 50 minutes). The debridement and external fixation were performed at first stage; then open reduction and internal fixation were used through anterior approach (reconstruction plate) and posterior approach (cannulated lag screws). The vacuum sealing drainage was performed during treatment until the wounds healed. Delayed healing of incison was obtained in 12 cases because of wound infection. Anatomical reduction or approximate anatomical reduction was achieved in all 12 cases. The patients were followed up 3-39 months (median, 18 months). No loosening of internal fixation or fracture displacement was observed during follow-up. The fracture healing time was 7-13 weeks (mean, 9.7 weeks). At last follow-up, according to the Matta standard, the outcome was excellent in 10 cases and good in 2 cases; according to Majeed score, the results were excellent in 9 cases, good in 1, and poor in 2. Early internal fixation operation of open Tile type C pelvic fractures can effectively restore the pelvic anatomical structure and stability, reduce the complication, and achieve satisfactory effectiveness.

    Surgical methods for type II odontoid fracture can be classified into 2 main groups: anterior or posterior approach. A more effective way to achieve bone fusion with the lowest possible surgical risk is needed. Therefore, the aim of our study was to describe and evaluate a novel technique, cable-dragged reduction/cantilever beam internal fixation for the treatment of type II odontoid fracture.This was a retrospective study enrolled 34 patients underwent posterior cable-dragged reduction/cantilever-beam internal fixation surgery. Medical records, rates of reduction, the location of the instrumentation and fracture healing during follow-up were analyzed. Once fracture healing was obtained, instrumentation was removed. Neck pain (scored using a visual analog scale [VAS]), neck stiffness, patient satisfaction, and neck disability index (NDI) were recorded before and after removing the instrumentation during follow-up.The mean duration of follow up was 22.8 ± 5.3 months. There was no iatrogenic damage to nerves or blood vessels. Radiographic evaluation showed complete reduction in the 20 patients with fracture displacement and satisfactory fracture healing in all 34 cases. Titanium cable breakage was observed in 4 patients after fracture healing. After removal of instrumentation, significant improvements were seen in neck-pain VAS score, neck stiffness, patient satisfaction, and NDI (all P dragged reduction/cantilever-beam internal fixation was an optimal salvage maneuver to conventional surgical methods such as anterior screw fixation and C1-C2 screw-rod system. The operative difficulty and incidence of nerve and vascular injury were reduced. Its major disadvantage is the exposure and screw-setting at C3, which is left intact in traditional surgery, and it is suitable only for patients with intact C1 posterior arches.

    Background Microwave is a method for improving fracture repair. However, one of the contraindications for microwave treatment listed in the literature is surgically implanted metal plates in the treatment field. The reason is that the reflection of electromagnetic waves and the eddy current stimulated by microwave would increase the temperature of magnetic implants and cause heat damage in tissues. Comparing with traditional medical stainless steel, titanium alloy is a kind of medical implants with low magnetic permeability and electric conductivity. But the effects of microwave treatment on fracture with titanium alloy internal fixation in vivo were not reported. The aim of this article was to evaluate the security and effects of microwave on healing of a fracture with titanium alloy internal fixation. Methods Titanium alloy internal fixation systems were implanted in New Zealand rabbits with a 3.0 mm bone defect in the middle of femur. We applied a 30-day microwave treatment (2,450MHz, 25W, 10 min per day) to the fracture 3 days after operation. Temperature changes of muscle tissues around implants were measured during the irradiation. Normalized radiographic density of the fracture gap was measured on the 10th day and 30th day of the microwave treatment. All of the animals were killed after 10 and 30 days microwave treatment with histologic and histomorphometric examinations performed on the harvested tissues. Findings The temperatures did not increase significantly in animals with titanium alloy implants. The security of microwave treatment was also supported by histology of muscles, nerve and bone around the implants. Radiographic assessment, histologic and histomorphometric examinations revealed significant improvement in the healing bone. Conclusion Our results suggest that, in the healing of fracture with titanium alloy internal fixation, a low dose of microwave treatment may be a promising method. PMID:24086626

    This meta-analysis aimed to compare the therapeutic effect of mini-plate versus Kirschner wire (K-wire) internal fixation on the treatment of metacarpal and phalangeal fractures among Chinese Han population. Databases of China National Knowledge Infrastructure (CNKI), Wanfang, Chinese VIP, PubMed, and Embase were retrieved for studies on mini-plate (case group) versus K-wire (control group) internal fixation for the treatment of metacarpal and phalangeal fractures among Chinese Han population. The odds ratio (OR) and standardized mean difference (SMD) at 95% confidence interval (CI) were used for estimating the effects of dichotomous data and continuous data, respectively. All statistical analyses were performed by Review Manager 5.2 software. A total of 18 studies involving 1,375 metacarpal or phalangeal fracture patients (709 cases and 666 controls) were included in the meta-analysis. There were significant differences in fracture healing time (SMD = -1.28; 95% CI: -1.81, -0.76), postoperative infection rate (OR = 0.25; 95% CI: 0.16, 0.39), complication incidence (OR = 0.24; 95% CI: 0.15, 0.38), and surgery time (SMD = 1.57; 95% CI: 0.76, 2.37) between the case and the control group, while no significant difference was found in hospital stays between these two groups (SMD = 0.43; 95% CI: -0.34, 1.20; P = 0.27). For the treatment of metacarpal or phalangeal fracture among Chinese Han population, mini-plate has advantages of shorter healing time and lower infection rate and complication incidence compared with K-wire internal fixation, while a longer surgery time than K-wire. In conclusion, mini-plate is prior than K-wire internal fixation for the treatment of metacarpal or phalangeal fracture among Chinese Han population.

    Full Text Available 【Abstract】 Objective: Monteggia fracture dislocation equivalent, though already described by Bado, is still an unclassified entity. We aimed to retrospectively analyze 18 cases of Monteggia variants and discuss the injury mechanisms, management, and outcome along with a review of the literature. Methods: A retrospective record of Monteggia fracture dislocation (2003-2008 was reviewed from medical record department of our institute. Classic Monteggia fracture dislocation, children below 12 years or adults over 50 years, as well as open grade II & III cases were excluded from this study. Monteggia variant inclusion criteria included fracture of the proximal ulna together with a fracture of the radial head or neck and skeletal maturity. Totally 26 patients were identified with Monteggia variants and 18 were available for follow-up, including 11 males and 7 females with the mean age of 35 years. The ulna fracture was treated by compression plating along with tension band wiring. Radial head/neck was reconstructed in 12 patients while excised in 6 patients. Results: Follow-up ranged from 1-4 years, mean 2.6 years. Patients were assessed clinicoradiologically. Mayo Elbow Performance Score was employed to assess the outcomes. At final follow-up, the results were excellent in 10 patients, good in 4, fair in 2 and poor in 2. Mean range of motion of the elbow was 20°, 116°, 50° and 55° for extension, flexion, pronation and supination, respectively. Two patients had complications in the form of heterotopic ossification and stiffness of the elbow. One nonunion ulna, primarily treated by tension band wiring, was managed by refixation with locking reconstruction plate and bone grafting. Bone grafting was only required in this patient for nonunion. Another patient had implants removed on his request. The results in our series closely correlated with extent of intraarticular damage, coronoid fracture and comminuted fractures. Conclusions: Monteggia

    Finite element analysis was used to compare preoperative and postoperative stress distribution of a bone healing model of femur fracture, to identify whether broken ends of fractured bone would break or not after fixation dislodgement one year after intramedullary nailing. Method s: Using fast, personalized imaging, bone healing models of femur fracture were constructed based on data from multi-slice spiral computed tomography using Mimics, Geomagic Studio, and Abaqus software packages. The intramedullary pin was removed by Boolean operations before fixation was dislodged. Loads were applied on each model to simulate a person standing on one leg. The von Mises stress distribution, maximum stress, and its location was observed. Results : According to 10 kinds of display groups based on material assignment, the nodes of maximum and minimum von Mises stress were the same before and after dislodgement, and all nodes of maximum von Mises stress were outside the fracture line. The maximum von Mises stress node was situated at the bottom quarter of the femur. The von Mises stress distribution was identical before and after surgery. Conclusion : Fast, personalized model establishment can simulate fixation dislodgement before operation, and personalized finite element analysis was performed to successfully predict whether nail dislodgement would disrupt femur fracture or not.

    Displaced fractures of the acetabulum involving the quadrilateral plate continue to be a surgical challenge. In this study, we describe our operation technique of auxiliary acetabular cerclage-wiring combined with plate osteosynthesis and present our results as well as short-term outcome. All patients aged 18 years and older treated with auxiliary cerclage-wiring between 2007 and 2012 were included in this study. Fractures were classified according to Letournel. Cerclage wiring was used when reposition and retention of the fracture was insufficient with plates and screws alone. Short-term outcome was evaluated by the German Short Musculoskeletal Functional Assessment (SMFA-D) questionnaire. Data from 23 patients were collected. The follow-up period was 7 months (range 2-23 months). Of the 23 patients, 22 showed excellent fracture reduction and retention. One patient had to undergo revision surgery due to loss of reposition. Patients showed good functional outcome. Auxiliary acetabular cerclage-wiring is a safe and effective method for fracture reduction and retention especially in displaced acetabular fractures involving the quadrilateral plate.

    Nylon cable tie has been shown to be an effective and economical method for fixing fractured ribs in the neonatal foal. This article describes a modification of the previously described technique. Under general anesthesia, the fractured ribs were exposed and a hole was drilled in the dorsal and ventral fragments. The fracture was not reduced, leaving the fragments overriding each other. The nylon cable tie was passed through the hole in the dorsal fragment from the external surface of the rib. The free end of the cable tie was then passed through the hole in the ventral fragment from the external surface of the rib and the tie was tightened. This technique was used in 4 neonatal foals with no complications. The modification of the original technique represents a method to minimize soft tissue trauma, implant failure, and complications.

  5. Open Reduction Internal Fixation of a Bimalleolar Ankle Fracture With Syndesmotic Injury.

    2016-08-01

    Rotational ankle fractures are incredibly common, resulting in a wide spectrum of bony and ligamentous injury patterns. After open reduction of an ankle fracture, the treating surgeon must always evaluate syndesmotic stability. If the syndesmosis is determined to be unstable, a reduction of the distal tibiofibular joint should be performed. Failure to adequately identify and treat injuries to the syndesmosis may result in continued ankle instability and poor patient outcomes. Lateral fluoroscopic images are necessary to assess a closed reduction of the syndesmosis before stabilization, although the accuracy of this tool has been questioned in several studies. Significant controversy surrounds many aspects of this injury and its treatment, including methods of diagnosis, ideal reduction clamp positioning, diameter and number of syndesmotic screws, and number of tibial cortices to be engaged. In the accompanying video, we describe our approach for the treatment of a bimalleolar ankle fracture with syndesmotic injury, using a posterior fibular plate and single tricortical syndesmotic screw.

    Although internal fixation is the definitive treatment in unstable pelvic fractures with disruption of the anterior arch and a vertical fracture of the sacrum (AO type C1.3), there have been no agreement of the best technique of internal fixation yet. We aimed to derive comparable objective data on stiffness and load to failure in this type of fracture fixations. Synbone was modified into AO type C1.3 fracture model, while treatments were divided into six internal fixation treatment groups using tension band plate (TBP), symphysis pubis plate (SP) with iliosacral screw at S1 and S2 (IS S1-S2), pubic screw (PS) with iliosacral TBP, PS and IS S1-S2, SP and IS S1-S3, PS and S1-S3 and finally PS and IS S1-S3. Sensor was applied to detect the shifting and rotation of fracture fragments. Mechanical strength test conducted with the application of axial force on the sacrum vertebra (S1). The highest translational stiffness was observed in the group IS S1-S3 + PS (830.36 N/mm, p = 0.031) and there was no difference on the rigidity of the rotation between the groups posterior fixation using IS S1-S2 and IS S1-S3 ( p = 0.51). Meanwhile the highest load to failure was found in group IS S1-S3 + PS (1522.20 N). PS provided advantages compared to the use of plate. Group of PS and S1-S3 IS is the configuration of internal fixation with best translational and rotational stiffness and the largest load to failure compared to other techniques in AO type C1.3 fracture.

    Intramedullary rodding allows excellent control of bending forces on long bone fractures when adequate sized rods are used. This is made possible by reaming when necessary. Torsional stability is poor if adequate bone nail contact is not obtained and there is little bone fragment interdigitation. This can be optimized with the interlocking system, especially with proximal and distal fractures. Intramedullary rods allow transmission of compressive load so there must be adequate bone to bone contact without comminution to prevent shortening. If a great deal of comminution is present, an interlocking system must be used to resist compressive loads. The interlocked devices have not been proven to be a detriment to union and indeed are a semi-rigid fixation system when used in comminuted shaft fractures. The strength of an osteosynthesis with an intramedullary rod depends on the geometry of the rod and the geometry of the fracture complex. Both locked and nonlocked intramedullary rods perform extremely well when one understands the mechanical principles involved in intramedullary rodding and pays close attention to detail.

    To explore the clinical effects of surgical treatment with cable dragged reduction and cantilever beam internal fixation by posterior approach for odontoid fracture associated with atlantoaxial dislocation. The clinical data of 12 patients with odontoid fracture associated with atlantoaxial dislocation from January 2008 to December 2013 were retrospectively analyzed. There were 8 males and 4 females, ranging in age from 21 to 53 years with an average of 37.2 years. Eleven cases were fresh fracture and 1 case was old fracture, all patients complicated with atlantoaxial anterior dislocation. According to Anderson-D' Alonzo typing method modified by Grauer, 3 cases were type IIA, 5 cases were type IIB, 3 cases were type IIC, and 1 case was type IIIA. All patients underwent surgical treatment with cable dragged reduction and cantilever beam internal fixation by posterior approach. JOA score and ADI method were respectively used to evaluate the nerve function and reductive condition of atlantoaxial dislocation. All patients were followed up from 6 months to 2 years with an average of 1 year and 3 months. At 1 week, 6 months after operation, and final follow up, JOA scores were 13.2±1.3, 13.5±1.4, 14.3±1.5, respectively, and these data were obviously better than that of preoperative 8.3±1.4( P dragged reduction and cantilever beam internal fixation by posterior approach for odontoid fracture associated with atlantoaxial dislocation is a good method, with advantage of firm fixation and high safety. It could obtain good clinical effects.

  11. Treatment of Atypical Ulnar Fractures Associated with Long-Term Bisphosphonate Therapy for Osteoporosis: Autogenous Bone Graft with Internal Fixation

    Directory of Open Access Journals (Sweden)

    Yohei Shimada

    2017-01-01

    Full Text Available Long-term bisphosphonate use has been suggested to result in decreased bone remodelling and an increased risk of atypical fractures. Fractures of this nature commonly occur in the femur, and relatively few reports exist to show that they occur in other bones. Among eight previous reports of atypical ulnar fractures associated with bisphosphonate use, one report described nonunion in a patient who was treated with cast immobilization and another described ulna nonunion in one of three patients, all of whom were treated surgically with a locking plate. The remaining two surgical patients achieved bone union uneventfully following resection of the osteosclerotic lesion and iliac bone grafting before rigid fixation. We hypothesized that the discontinuation of bisphosphonate therapy, the use of teriparatide treatment, and low-intensity pulsed ultrasound (LIPUS might have been associated with fracture healing.

    Thoracic spine fractures has a high social impact because of its frequent association with neurological deficit. There is much controversy about the way to treat them: using transpedicular screws (Roy Camille), books (Harrington) or sublaminar wires (Luque) systems. Forty patients were reviewed in time span from 1993 to 2002; average age 37 years, average follow up 54 months. The analyzed variables were: technique used, diagnostic, mechanism of trauma, neurological deficit, additional injuries, decompressive procedures, anatomic level and complications. There were 28 (70%) luxofractures. The causes of the injuries found were 21 (52%) cases of vehicle motor accidents. 24 patients (60%) had neurological deficit and seven of them required decompression procedures, the mean of levels fixed per patient were seven. the modified Harrington-Luque technique was used in 26 patients and the modular technique was used in 14. The complications presented were two acute infections

    To compare the clinical effects and safety of dynamic external fixtor combined with limited internal fixation and cross K-wires fixation for the treatment of close Pilon fractures of the proximal interphalangeal joint. From June 2012 to June 2014, totally 41 patients (45 fingers) with close interphalangeal joint Pilon fracture were treated by dynamic external fixtor combined with limited internal fixation or cross K-wires fixation, and all the patients were followed up. In the dynamic external fixtor combined with limited internal fixation group (group A), there were 21 patients with 22 fingers, including 12 males and 9 females, with an average of (30.6±5.6) years old. In the cross K-wires fixation group (group B), there were 20 patients with 23 fingers, including 11 males and 9 females, with an average of (30.1±5.3) years old. Regular re-examination of X-ray was performed to evaluate the active range of joint motion, fracture healing time, infection rate and postoperative joint motion pain. According to the evaluation criteria of upper extremity function issued by the Hand Surgery Society of Chinese Medical Association, the excellent and good cases of group A was up to 19 and 13 for group B. The evaluation results has significant differences (Z=2.558, P=0.011). The excellent and good rate of group A was obviously higher than that of group B. The average bone union time of group A was (7.9±2.1) weeks, and (8.1±2.3) weeks for group B. There was no significant difference on the mean healing time (t=-0.304, P=0.762). The infection fingers of group A was 5, and 1 for group B. The difference between the results was statistically significant (χ2=3.287, Pexternal fixtor combined with limited internal fixation is a reliable and effective method to treat Pilon fractures of the proximal interphalangeal joint. It allows early postoperative functional rehabilitation and restores the joint function.

    Abdelgaid, Sherif Mohamed; Ezzat, Farid Fouad

    2012-12-01

    Fracture neck talus is a rare fracture represents about 1% of all fractures and usually due to high energy trauma. These fractures are usually associated with compromised soft tissues, concomitant skeletal fractures, or life threatening injuries. Talus has a tenuous blood supply which is affected by fracture displacement. Urgent fracture reduction±fracture fixation is mandatory. The associated injuries may make the conventional open reduction and internal fixation is impossible to be done in urgent base as it may impacts the already tenuous blood supply of talus increasing the risk of AVN and non union. Percutaneous fracture reduction and fixation can overcome this problem, and decrease complications associated with conventional open reduction and internal fixation. Between 2006 and 2008, 16 patients with talar neck fractures were operated on by percutaneous reduction of fracture and percutaneous fixation with 3.5mm cannulated screws. Injuries were classified according to modified Hawkins classification system. Patients were followed up over an average of 48 months. 87.5% of the patients were satisfied and resumed their preoperative activities. The mean AOFAS Hind Foot Scale was 89.25 points (range: 74-100) and no poor outcomes. Although the number of patients in this study is small, the results showed that, percutaneous reduction and fixation is a good treatment modality in treatment of fracture neck talus, especially in cases with increased risk of soft tissue complications and open reduction should be resort only when percutaneous reduction was failed.

  15. Preliminary experience with biodegradable implants for fracture fixation

    2008-01-01

    Full Text Available Background: Biodegradable implants were designed to overcome the disadvantages of metal-based internal fixation devices. Although they have been in use for four decades internationally, many surgeons in India continue to be skeptical about the mechanical strength of biodegradable implants, hence this study. Materials and Methods: A prospective study was done to assess the feasibility and surgeon confidence level with biodegradable implants over a 12-month period in an Indian hospital. Fifteen fractures (intra-articular, metaphyseal or small bone fractures were fixed with biodegradable implants. The surgeries were randomly scheduled so that different surgeons with different levels of experience could use the implants for fixation. Results: Three fractures (one humeral condyle, two capitulum, were supplemented by additional K-wires fixation. Trans-articular fixator was applied in two distal radius and two pilon fractures where bio-pins alone were used. All fractures united, but in two cases the fracture displaced partially during the healing phase; one fibula due to early walking, and one radius was deemed unstable even after bio-pin and external fixator. Conclusions: Biodegradable -implants are excellent for carefully selected cases of intra-articular fractures and some small bone fractures. However, limitations for use in long bone fractures persist and no great advantage is gained if a "hybrid" composite is employed. The mechanical properties of biopins and screws in isolation are perceived to be inferior to those of conventional metal implants, leading to low confidence levels regarding the stability of reduced fractures; these implants should be used predominantly in fracture patterns in which internal fixation is subjected to minimal stress.

    The purpose of this study was to investigate the timing of surgical intervention for fractures of the acetabulum and its influence on perioperative factors. Retrospective review. Level I trauma center. Two hundred eighty-eight consecutive patients who sustained either posterior wall (PW), associated both column (ABC), or anterior column posterior hemitransverse (ACPHT) acetabulum fractures were included in the study. One hundred seventy-six PW fractures were treated through a Kocher-Langenbeck approach, and 112 ABC/ACPHT fractures were treated through an anterior intrapelvic approach. Estimated blood loss (EBL), operative time. EBL (800 vs. 400 mL), operative time (270 vs.154 minutes), and hospital stay (11 vs. 7 days) were greater for the ABC/ACPHT fractures compared with the PW fractures. When comparing early (≤48 hours) versus late (>48 hours) treatment of PW fractures, there was no difference in EBL (400 vs. 400 mL, P = 0.37) or operative time (150 vs. 156 minutes, P = 0.50). In comparison of early versus late treatment of ABC/ACPHT fractures, no significant difference was noted in EBL (725 vs. 800 mL, P = 0.30) or operative time (258.5 vs. 272 minutes, P = 0.21). We found no advantage or disadvantage in terms of EBL or operative time for early (≤48 hours) versus late (>48 hours) fixation for either PW or ABC/ACPHT acetabular fractures. Therapeutic Level III.

    The indications for arthroscopy have expanded over the years. Arthroscopic-assisted open reduction internal fixation in the setting of acute trauma is gaining popularity with foot and ankle surgeons. It serves to facilitate direct visualization of fracture fragments and allows for precise articular reduction with minimal soft tissue insult. Current evidence reports a high incidence of chondral injury with ankle fractures. Arthroscopy performed at the time of open reduction internal fixation allows for joint inspection and potential treatment of these posttraumatic defects. Copyright © 2017 Elsevier Inc.

    Full Text Available Background: The best operative management for open-book pelvic injury with anterior sacroiliac disruption (OTA/AO B1.1 classification is still debated. This biomechanical study aimed to find the best internal fixation technique for such injury. Methods: Open-book injury with anterior sacroiliac joint disruption was simulated on 25 artificial pelvic bones. Twenty five artificial pelvic bones were divided into 5 groups (n=5 /group and fixated with five different fixation techniques: 1. 1SP+1IS; 2. 2SP; 3. 2SP+2SIP; 4. 1SP+2IS S1, and 5. 1SP+1IS S1+S2. Biomechanical properties of each fixation technique were assessed using Tensilon® RTF-1310 to measure the resistance to translation and load to failure. Data were statistically analyzed using one-way ANOVA followed by post-hoc Bonferroni test.Results: The highest mean load to failure of axial forces (1490.36 N was achieved by the fixation technique using one symphyseal plate and two iliosacral screws located at S1 dan S2. The addition of one iliosacral screw significantly increased the mean load to failure for axial compression (p<0.05.Conclusion: The addition of sacroiliac joint posterior fixation, either with plate or screw, will increase the fixation biomechanical strength. Single symphyseal plate and two iliosacral screws on S1 and S2 provided the best mechanical resistance to axial loading. Thus, it can be concluded that such fixation technique is best for open-book pelvic injury with anterior sacroiliac disruption.

    Treatment modalities of mandibular angle fractures (MAFs) have been analyzed in several studies mainly referring to adult populations. The aim of this study was to retrospectively present and discuss our experience and literature findings regarding the treatment of MAFs in children. Data were retrieved from the files of the Oral and Maxillofacial department, at the Children's Hospital ''P. & A. Kyriakou'' of Athens, during a 5 years period (2009-2013). Demographic features, treatment methods, outcome and follow-up of all patients with mandibular angle fractures were recorded. 6 boys, 5-14 years old (mean age 10 years), were included in the study. They were all treated intraorally with open reduction and fixation via one monocortical titanium plate osteosynthesis at the external oblique line of the mandible, followed by 1 week of intermaxillary fixation (IMF). Plates were removed 3-12 months post-operatively. Follow-up period ranged from 12 to 18 months (mean 14.7 months). All fractures healed uneventfully and the patients tolerated well both the operation and the post-operative period. Osteosynthesis via intraoral approach combined with short duration IMF is adequate in treating MAFs in children. Copyright © 2014 European Association for Cranio-Maxillo-Facial Surgery.

    Calcaneus fractures are still a delicate point regarding the indication for osteosynthesis. Knowing the skin's poor vascularisation of the back foot, the purpose of this study is to present the benefits of proper surgical options between an open and invasive osteosynthesis with anatomical reduction and internal fixation or minimally invasive approach preserving the quality of the soft parts. 66 interventions that targeted reduction and internal fixation of calcaneus fractures were performed between 2009-2012, in the Orthopaedic and Traumatology Department of Bucharest Emergency University Hospital. 29 cases underwent open reduction and internal fixation with plates and screws or Kirschner wires, and 37 cases underwent a minimally invasive reduction and Essex Lopresti osteosynthesis technique. No patient who underwent a minimally invasive reduction had skin lesions, but showed pain due to osteoarthritis lesions that appeared in the subtalar joint. 4 of them, who underwent open reduction and internal fixation had postoperative wound infections and skin necrosis.

    To evaluate effectiveness of allogeneic bone screws and pins for internal fixation of midbody transverse fractures of equine proximal sesamoid bones (PSBs) in vitro. 14 forelimbs from cadavers of 3-year-old Thoroughbreds. Allogeneic cortical bone fragments were collected from the limbs of a male Thoroughbred, and cortical bone screws were prepared from the tissue by use of a precision desktop microlathe programmed with the dimensions of a metal cortical bone screw. A midbody transverse osteotomy of each PSB was performed by use of a bone-shaping oscillating saw and repaired via 1 of 3 internal fixation techniques: 1 allogeneic bone screw with 1 allogeneic bone pin (type I; n = 6 PSBs), 2 allogeneic bone screws (type II; 8), or 1 stainless steel cortical bone screw (control repair; 6). Mechanical tension measurements were obtained by use of a commercially available materials testing system. Mean +/- SD tensile strength (TS) was 668.3 +/- 216.6 N for type I repairs, 854.4 +/- 253.2 N for type II repairs, and 1,150.0 +/- 451.7 N for control repairs. Internal fixation of PSB fractures by the use of allogeneic bone screws and bone pins was successful. Although mean TS of control repairs with stainless steel cortical bone screws was greater than the mean TS of type I and type II repairs, the difference between type II and control repairs was not significant. Allogeneic screws may advance healing and result in fewer complications in a clinical setting.

    To investigate the methods and effectiveness of one-stage operation for pelvis and acetabular fractures combined with Morel-Lavallée injury by internal fixation associated with vacuum sealing drainage (VSD). Between June 2008 and October 2012, 15 cases of pelvis and acetabular fractures combined with Morel-Lavallée injury were treated. There were 5 males and 10 females, aged from 18 to 67 years (mean, 36.8 years). Fractures were caused by traffic accident in 11 cases and crashing injury of heavy object in 4 cases. The time from injury to hospitalization was 3 hours to 9 days (mean, 5.4 days). Morel-Lavallée injury located in the above posterior superior iliac spine in 4 cases, greater trochanter in 7 cases, and anterior proximal thigh in 4 cases. In 10 cases complicated by pelvic fracture, there were 1 case of anteroposterior compression type, 3 cases of lateral compression type, 5 cases of vertical shear type, and 1 case of compound injury type; in 5 cases complicated by acetabular fracture, there were 1 case of transverse fracture, 1 case of posterior wall and posterior column fracture, 1 case of transverse acetabulum plus posterior wall fracture, and 2 cases of both columns fracture. Open reduction and internal fixation were used to treat pelvic and acetabular fractures, and VSD to treat Morel-Lavallée injury. When the drainage volume was less than 20 mL/d, interrupted wound suture or free skin grafting was performed. The hospitalization time was 16-31 days (mean, 20.8 days). Thirteen cases were followed up 4-16 months (mean, 7.8 months). The healing time of Morel-Lavallée injury was 16-36 days after operation (mean, 21.3 days). All the wounds had primary healing, and no infection occurred. The X-ray films showed that all fractures healed, with a mean healing time of 13.6 weeks (range, 11-18 weeks). At 6.5 months after operation, according to Majeed function scoring system in 8 cases of pelvic fracture, the results were excellent in 5 cases, good in 2 cases

    Full Text Available OBJECTIVE: This study aimed to evaluate the preliminary clinical and radiographic outcomes of acute displaced femoral neck fracture treated by closed reduction and internal fixation (CRIF with free iliac bone block grafting with comparison to a routine protocol of CRIF without bone grafting. METHODS: From December 2008 to February 2010, 220 adult patients with acute displaced femoral neck fractures were enrolled in this study. In study group, there were 124 patients (57 males, 67 females with a mean age of 44.8 years (range, 20-64 years. There were 70 transcervical fractures and 54 subcapital fractures. The patients were treated by CRIF and free iliac bone block grafting. The control group consisted of 96 adult patients (46 males, 50 females with a mean age of 46.3 years (range, 23-64 years. There were 61 transcervical fractures and 35 subcapital fractures. The patients in control group were treated by CRIF without bone grafting. RESULTS: In study group, 112 patients were followed up for an average of 27.4 months (range, 24-34 months. All fractures healed within 5 months. However, 10 patients presented AVN of the femoral heads. The mean Harris score was 88.6 (range, 41-100. In control group, 68 patients were followed up for an average of 31.2 months (range, 24-42 months. The rates of AVN of the femoral head and fracture nonunion in control group were 26.5% (18/68 and 16.2% (11/68, respectively, significantly higher than those in study group (both P<0.05. The mean Harris score in control group was 83.8 (41-100, significantly lower than that in study group (P<0.05. CONCLUSION: Acute displaced femoral neck fractures can be treated by CRIF and free iliac bone block grafting in a minimally invasive manner. This technique can guarantee uneventful fracture healing and significantly reduce the rate of femoral head osteonecrosis.

    Avascular necrosis (AVN) of the femoral head is a major complication after internal fixation of a femoral neck fracture and determines the functional prognosis. We investigated postoperative bone single-photon emission computed tomography/computed tomography (SPECT/CT) for assessing the risk of femoral head AVN. We retrospectively reviewed 53 consecutive patients who underwent bone SPECT/CT within 2 weeks of internal fixation of a femoral neck fracture and follow-up serial hip radiographs over at least 12 months. Nine patients developed femoral head AVN. In 15 patients who showed normal uptake on immediate postoperative SPECT/CT, no AVN occurred, whereas 9 of 38 patients who showed cold defects of the femoral head later developed AVN. The negative predictive value of immediate postoperative SPECT/CT for AVN was 100 %, whereas the positive predictive value was 24 %. Among 38 patients with cold defects, 1 developed AVN 3 months postoperatively. A follow-up bone SPECT/CT was performed in the other 37 patients at 2–10 months postoperatively. The follow-up bone SPECT/CT revealed completely normalized femoral head uptake in 27, partially normalized uptake in 8, and persistent cold defects in 2 patients. AVN developed in 3.7 % (1/27), 62.5 % (5/8), and 100 % (2/2) of each group, respectively. According to the time point of imaging, radiotracer uptake patterns of the femoral head on postoperative bone SPECT/CT indicate the risk of AVN after internal fixation of femoral neck fractures differently. Postoperative bone SPECT/CT may help orthopedic surgeons determine the appropriate follow-up of these patients.

    The purpose of this study was the comparison of the most commonly used surgical techniques (external fixation, intramedullary nailing, and plate fixation) for the treatment of distal tibial fractures (AO/OTA classification 42-A, B, C or 43-A, B1). A retrospective cohort study of patients who underwent surgical treatment for distal tibial fractures between 1992 and 2011 was performed. A total of 93 patients (52 male/41 female) met inclusion criteria. Statistically significant differences were found regarding the consolidation time of the intramedullary-nailing (147.32 ± 91.16 days) and the plate-fixation group (135.75 ± 110.75 days) versus the external-fixation group (163.12 ± 96.79 days; P = 0.001; P = 0.01). Significant differences were also observed in the range of motion (ROM) of the ankle joint in the intramedullary-nailing and plate-fixation group versus the ROM in the external-fixation group (P = 0.044; P = 0.025). The overall complication rate was 13/93 (14 %). Out of 66 patients treated with intramedullary nailing, 8 (12 %) suffered from complications. Out of the 15 patients treated with plate and 12 patients with external fixation, 2 (13 %) and 3 (25 %) showed complications, respectively. Our results demonstrate advantages in terms of shorter mobilization time and a better ROM of the ankle joint for intramedullary nailing and plate fixation compared with external fixation. Due to our results, we suggest internal fixation (intramedullary nailing or plate fixation) whenever patient's condition and the local fracture situation allow it.

    Surgical management of calcaneus fractures is technically demanding and has a high risk of wound complications. These fractures are traditionally managed with splinting until swelling has subsided, which can take weeks and leaves the fracture fragments displaced. We describe a novel protocol for the management of displaced intraarticular calcaneus fractures that utilises a temporising external fixator and staged conversion to plate fixation through a sinus tarsi approach. The goal of this technique was to enable earlier treatment with open reduction and internal fixation, minimise the amount of manipulation required at the time of definitive fixation and reduce the wound complication rate seen with the traditional extensile approach. The records of patients with displaced calcaneus fractures from 2010-2014 were reviewed retrospectively. A total of nine patients with 10 calcaneus fractures were treated using this protocol. All patients underwent ankle-spanning medial external fixation within 48 hours after injury. Patients underwent conversion to open plate fixation through a sinus tarsi approach when skin turgor had returned to normal. Time to surgery, infection rate, wound complications, radiographic alignment, and time to radiographic union were recorded. The average Bohler's angle improved from 13.2 (range -2 to 34) degrees preoperatively to 34.3 (range 26 to 42) degrees postoperatively. The average time from external fixation to conversion to internal fixation was 4.8 (range 3 to 7) days. There were no immediate post-surgical complications. The average time to weight-bearing was 8.5 weeks. The average time to radiographic union was 9.5 (range 8 to 12) weeks. There were no infections or wound complications at the time of last follow-up. Early temporising external fixation for the acute management of displaced calcaneus fractures is a safe and effective method to reduce and stabilise the foot and may decrease the time to definitive fixation. There were no

    We developed the acetabular tridimensional memory alloy-fixation system (ATMFS), which is made of NiTi shape memory alloy, according to the specific mechanical properties of biological memory material, nitinol alloy and measured distribution of contact area and pressure between the acetabulum and the femoral head of cadaveric pelvis. Six formalin-preserved cadaveric pelvis were used for this investigation. Pressure-sensitive film was used to measure contact area and pressure within the anterior, superior, and posterior regions of the acetabulum. The pelvis were loaded under the following four conditions: (1) intact; (2) following a creation posterior wall fracture defect; (3) following reduction and standard internal fixation with reconstruction plate; (4) following reduction and internal fixation with a new shape memory alloy device named ATMFS. A posterior wall fracture was created along an arc of 40-90 degrees about the acetabular rim. Creation of a posterior wall defect resulted in increased load in the superior acetabulum (1422N) as compared to the intact condition (762N, P=0.007). Following reduction and internal fixation, the load distributed to the superior acetabulum (1486N) was not statistically different from the defect condition. Following the fixation with ATMFS, the load seen at the superior region of the actabulum (936N) was less than fixation with reconstruction plate and was not different from intact state (P=0.4). These data indicate that the use of ATMFS as a fracture internal fixation device resulted a partial restoration of joint loading parameters toward the intact state. ATMFS fixation may result in a clinical benefit. Copyright 2010 Elsevier Ltd. All rights reserved.

    The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Because MRI may overdiagnose or overestimate the extent of OCLs in an acute trauma setting the aim of this study was to determine the incidence of OCLs after ORIF of displaced ankle fractures using MRI at medium-term follow-up, and to analyse if the severity of fracture or the clinical outcome correlates with the incidence of OCLs. Following institutional review board approval a total of 100 patients (mean age, 41.3 years; range, 17.9-64.3 years) with a displaced ankle fracture who had undergone ORIF according to the AO principles were included in this study. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used to quantify the clinical outcome and MR images were evaluated for OCLs of the talus and distal tibia after a mean of 34.5 months (range, 17.5-54.1 months). OCLs were found in 40.4% of the patients. Logistic regression revealed a significant correlation between the severity of fracture and the incidence of OCLs. Patients with a trimalleolar fracture (p=0.04) or an ankle fracture dislocation (p=0.003) had a significantly higher risk for developing an OCL compared to those with a type B fracture. Logistic regression also demonstrated a significant correlation between the clinical outcome (AOFAS score) and the incidence of OCLs (p=0.01). The risk for developing an OCL increases up to 5.6% when the AOFAS score decreases by one point. OCLs were frequently found in association with acute ankle fractures at medium-term follow-up, and the severity of fracture was associated with an increased number of OCLs. Considering the disadvantages of MRI including the high cost and limited availability, the results of this study may help to explain why anatomic surgical realignment of displaced

    To present a novel single anterior-lateral approach for the treatment of distal tibia and fibula fracture via anatomical study and primary clinical application in order to minimize soft tissue complications. Both a gross anatomic cadaver and retrospective studies of the single-incision technique in patients recruited between June 2004 and January 2010. Level I trauma center. Twenty-six legs of 14 adult human cadavers and clinical recruitment of 49 patients (29 males, 20 females) with a mean age of 37.6 years (range 11-68) with fracture of distal 1/3 tibia and fibula. A single anterior-lateral incision technique for open reduction and internal fixations of distal tibia and fibula fractures. To identify the anatomic structures at risk in the anterolateral aspect of the lower leg and explicit the safe dissection distance from the extensor digitorum longus (EDL) to tibia and fibula, 26 legs of 14 adult human embalmed specimens were recruited in the anatomical study with the distance between the EDL and the anterior edge of the distal thirds of the tibia, as well as the distance between the EDL and the anterior edge of the distal thirds of the fibula were measured, and their mutual relationships to the surrounding anatomical structures described. Mean average standard deviations were also calculated. As for the clinical study, the quality of bone union and soft tissue healing were noted. The mean distances between the distal tibia and the EDL were measured to be 2.96 ± 0.46 cm (proximal), 1.85 ± 0.25 cm (middle), and 2.15 ± 0.30 cm (distal), and that between the fibula and the EDL were 1.82 ± 0.28 cm (proximal), 2.09 ± 0.31 cm (middle), and 2.30 ± 0.27 cm (distal), which means the safe gap from the distal tibia to EDL was 1.6-3.4 cm and from the EDL to fibula was 1.5-2.6 cm. The anterior tibial vein and artery and the deep fibular nerve lie on the anterior interosseous membrane over the lateral surface of the distal tibia were excellently visualized. Review of

    Locking plates are increasingly used to surgically treat proximal humerus fractures. Knowledge of the bone quality of the proximal humerus is important. Studies have shown the medial and dorsal aspects of the proximal humeral head to have the highest bone strength, and this should be exploited by fixation techniques, particularly in elderly patients with osteoporosis. The goals of surgery for proximal humeral fractures should involve minimal soft tissue dissection and achieve anatomic reduction of the head complex with sufficient stability to allow for early shoulder mobilization. This article reviews various treatment options, in particular locking plate fixation. Locking plate fixation is associated with a high complication rate, such as avascular necrosis (7.9%), screw cutout (11.6%), and revision surgery (13.7%). These complications are frequently due to the varus deformation of the humeral head. Strategic screw placement in the humeral head would minimize the possibility of loss of fracture reduction and potential hardware complications. Locking plate fixation is a good surgical option for the management of proximal humerus fractures. Complications can be avoided by using better bone stock and by careful screw placement in the humeral head.

    To evaluate the diagnostic efficacy of technetium-99m-methylene diphosphonate ((99m)Tc-MDP) three phase bone scintigraphy in detecting infection in malunion or nonunion traumatic fractures after internal fixation. One hundred and eighty four patients with malunion or nonunion fractures after internal fixation (130 men and 54 women; age range, 16-79 years) underwent (99m)Tc-MDP three phase bone scintigraphy (3PBS). They were divided into the infection group (n=96) and the control group without infection (n=88) based on the final diagnosis after operation. The sensitivity, specificity, accuracy, positive prediction value (PPV) and negative prediction value (NPV) were calculated and compared. All patients carried out other laboratory tests related to infection such as complete serum blood cells count, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). The (99m)Tc-MDP 3PBS for the blood flow phase showed sensitivity, specificity, accuracy, positive predictive value and negative predictive value, 91.7% (88/96), 72.7% (64/88), 82.6% (152/184), 78.6% (88/112) and 88.9% (64/72), respectively and for the blood pool phase, 93.8% (90/96), 61.4% (54/88), 78.3% (144/184), 72.6% (90/124) and 90.0% (54/60) respectively. The semiquantitative indices of the ratio between the abnormal and the normal region of interest (ROI), called by us the A/N ratio, for both blood flow and blood pool phases as estimated between the infection group and the control group were statistically different. It is the opinion of the authors that (99m)Tc-MDP 3PBS provided high predictive values in diagnosing infection in patients with malunion or nonunion traumatic fractures after internal fixation. The diagnostic value of blood flow and blood pool phases estimated of the 3PBS was better than the laboratory indices: white blood cell counts, CRP, and ESR.

    Analyzing the different age groups in a population who suffered a pelvic ring fracture it becomes obvious that there are important differences between the pelvic ring lesions of an elderly patient compared to a young adult concerning trauma mechanism, fracture pattern and therapeutic options. In the elderly patient it is very important to achieve maximum of stability if surgery is necessary in order to avoid early failure of the ostheosynthesis under mobilization with full weight bearing. 15 patients (14 female) with fragility fractures of the pelvis that required surgical stabilization were eligible to participate in this study from December 2012 to December 2014. Such details were documented and analysed as patient demographics, mechanism of injury, fracture classification, operative treatment and postoperative radiological parameters of achieved bone-implant interface. The average age of the patients was 79.9 years (SD 9.0 years). According to Rommens five patients had a fragility fracture of the pelvis Type II-c, one a Type III-c, six a Type IV-b and three a Type IV-c. Four patients were treated by a cement augmented transiliac internal fixation (caTIFI). Seven patients received a cement augmented iliolumbar fixation. In all these patients the Schanz screws applied to the ilium were placed in an oblique dorsoventral direction into the supraacetabular bone canal (mean length of screws 100 ± 20mm, max. 135 mm, min. 70 mm). Even though in four patients the iliosacral joint was hit tangential and one cortex perforation without any cement leakage appeared no revision surgery was necessary. Overall the clinical findings including mobilisation with full weight bearing showed a sufficient mechanically stability in all patients. The focus of this study was to describe the modified surgical technique of the caTIFI with placing the Schanz screws from the posterior superior iliac spine to the anterior inferior iliac spine into the supraacetabular bone canal.

    Full Text Available We report the case of an 82-year-old woman who developed extensive proximal thigh swelling and persistent anaemia following internal fixation of an extracapsular neck of femur fracture with a dynamic hip screw (DHS. This was revealed to be a pseudoaneurysm of a branch of profunda femoris artery on angiography. Her case was further complicated by a concurrent pulmonary embolism (PE. She underwent endovascular coil embolisation of the pseudoaneurysm. An IVC filter was inserted and the patient was fully anticoagulated once it had been ensured that there was no active bleeding. In this case, we review the potential for anatomical variations in the blood supply to this region and discuss treatment options for a complicated patient. We recommend that a pseudoaneurysm should be part of a differential diagnosis for postoperative patients with anaemia refractory to blood transfusion so as not to miss this rare but potentially serious complication.

    Axillary nerve injuries after shoulder surgery are rare. In most studies, the frequency of injury is usually determined using clinical examinations, but results from intraoperative neuromonitoring studies have revealed higher than expected rates. Few studies have investigated this topic. Our aim was to determine the frequency of axillary nerve lesions after open reduction and internal fixation of proximal humeral fractures by using electrophysiological assessments and to provide a review of the relevant literature. This was a retrospective cohort study of 76 consecutive patients who received open reduction and internal fixation of a proximal humeral fracture using a locking plate through a deltoid-splitting approach. We performed a clinical and electrophysiological examination at a minimum follow-up time of 12 months. Functional results were assessed according to the Constant-Murley and Disabilities of the Arm, Shoulder and Hand scores. Electrophysiological examinations comprised electromyography, electroneurography, and motor and somatosensory evoked potentials. The main outcome was the frequency of axillary nerve lesions. Forty patients were monitored for an average of 28 months. The mean raw Constant-Murley score was 61 points, the age- and gender-adjusted score was 71%, and the mean Disabilities of the Arm, Shoulder and Hand score was 33 points. Neurapraxia occurred in 1 patient, axonotmesis with incomplete reinnervation occurred in 3, and complete reinnervation occurred in 3. The latter group was classified as having a temporary axillary nerve lesion. The 10% rate of permanent axillary nerve lesions in our cohort is higher than expected based on the clinical examination. Electrophysiological assessment is therefore more appropriate to detect axillary nerve injuries. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

    The aim of this study is to compare two methods of internal fixations of fractured medial malleolus which are simple screw fixation and tension band wiring. Over 5 years we grouped 20 patients with fractured medial malleolus into two groups of operative treatments, group1 treated by malleolar screw fixation and group2 by tension band wiring. The patients were with same age group, gender, fracture type, and etiology. We use statistical analysis for make a comparative study between the two ways of surgical treatment. The mean time for radiologic bone union was 11.8 weeks in group1 patients and 9.4 weeks in group2 patients (P = 0.03). No patients had any sign of fixation failure or Kirschner wires migration. According to the modified ankle scoring system of Olerud and Molander, excellent and good results were achieved in 80 % in group1 patients and 90 % in group2 patients (P = 0.049). Tension-band wiring may be better treatment option for internal fixation of medial malleolar fractures than screw fixation. From these findings we recommend a further randomized clinical trial of larger number of cases and longer follow-up duration in order to regard tension-band wiring a better operative option for fixation of medial malleolar fractures.

    One hundred and twenty-seven consecutive patients with displaced subcapital fractures of the femoral neck (Garden Grade III or IV) all under 80 years of age and independently mobile, were randomly allocated to fixation with either double divergent pins or a single sliding screw-plate device. The incidence of non-union and infection in the sliding screw-plate group was significantly higher, and we believe that when internal fixation is considered appropriate multiple pinning should be used. Mobility after treatment was disappointing in about half of the patients, and we feel that internal fixation can only be justified in patients who are physiologically well preserved and who maintain a high level of activity.

    There are relatively few studies in the literature that specifically evaluate accelerated rehabilitation protocols for distal radial fractures treated with open reduction and internal fixation (ORIF). The purpose of this study was to compare the early postoperative outcomes (at zero to twelve weeks postoperatively) of patients enrolled in an accelerated rehabilitation protocol with those of patients enrolled in a standard rehabilitation protocol following ORIF for a distal radial fracture. We hypothesized that patients with accelerated rehabilitation after volar ORIF for a distal radial fracture would have an earlier return to function compared with patients who followed a standard protocol. From November 2007 to November 2010, eighty-one patients with an unstable distal radial fracture were prospectively randomized to follow either an accelerated or a standard rehabilitation protocol after undergoing ORIF with a volar plate for a distal radial fracture. Both groups began with gentle active range of motion at three to five days postoperatively. At two weeks, the accelerated group initiated wrist/forearm passive range of motion and strengthening exercises, whereas the standard group initiated passive range of motion and strengthening at six weeks postoperatively. Patients were assessed at three to five days, two weeks, three weeks, four weeks, six weeks, eight weeks, twelve weeks, and six months postoperatively. Outcomes included Disabilities of the Arm, Shoulder and Hand (DASH) scores (primary outcome) and measurements of wrist flexion/extension, supination, pronation, grip strength, and palmar pinch. The patients in the accelerated group had better mobility, strength, and DASH scores at the early postoperative time points (zero to eight weeks postoperatively) compared with the patients in the standard rehabilitation group. The difference between the groups was both clinically relevant and statistically significant. Patients who follow an accelerated rehabilitation

    Controversy exits over the role of Böhler's angle in assessing the injury severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following internal fixation. This study aims to investigate whether a correlation exists between Böhler's angle and the injury severity of displaced calcaneal fractures, and between surgical improvement of Böhler's angle and functional outcome. Patients treated operatively for unilateral closed displaced intra-articular calcaneal fractures from January 1, 2004 to March 31, 2008 were identified. The Böhler's angles of both calcaneus were measured, and the measurement of the uninjured foot was used as its normal control. The difference in the value of Böhler's angle measured preoperatively or postoperatively between the angle of the injured foot and that of the contralateral calcaneus were calculated, respectively. The change in Böhler's angle by ratio was calculated by dividing the difference value of Böhler's angle between bilateral calcaneus by its normal control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot & Ankle Society hindfoot scores. 274 patients were included into the study with a mean follow-up duration of 71 months. According to Sanders classification, the fracture pattern included 105 type II, 121 type III and 48 type IV fractures. According to American Orthopaedic Foot & Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 104, 132, 27, and 11 patients, respectively. The preoperative Böhler's angle, difference value of Böhler's angle between bilateral calcaneus, and change in Böhler's angle by ratio each has a significant correlation with Sanders classification (rs=-0.178, P=0.003; rs=-0.174, P=0.004; rs=-0.172, P=0.005, respectively), however, is not correlated with functional outcome individually.

  3. Design and Optimization of Resorbable Silk Internal Fixation Devices

    Science.gov (United States)

    Haas, Dylan S.

    Limitations of current material options for internal fracture fixation devices have resulted in a large gap between user needs and hardware function. Metal systems offer robust mechanical strength and ease of implantation but require secondary surgery for removal and/or result in long-term complications (infection, palpability, sensitivity, etc.). Current resorbable devices eliminate the need for second surgery and long-term complications but are still associated with negative host response as well as limited functionality and more difficult implantation. There is a definitive need for orthopedic hardware that is mechanically capable of immediate fracture stabilization and fracture fixation during healing, can safely biodegrade while allowing complete bone remodeling, can be resterilized for reuse, and is easily implantable (self-tapping). Previous work investigated the use of silk protein to produce resorbable orthopedic hardware for non- load bearing fracture fixation. In this study, silk orthopedic hardware was further investigated and optimized in order to better understand the ability of silk as a fracture fixation system and more closely meet the unfulfilled market needs. Solvent-based and aqueous-based silk processing formulations were cross-linked with methanol to induce beta sheet structure, dried, autoclaved and then machined to the desired device/geometry. Silk hardware was evaluated for dry, hydrated and fatigued (cyclic) mechanical properties, in vitro degradation, resterilization, functionalization with osteoinductive molecules and implantation technique for fracture fixation. Mechanical strength showed minor improvements from previous results, but remains comparable to current resorbable fixation systems with the advantages of self-tapping ability for ease of implantation, full degradation in 10 months, ability to be resterilized and reused, and ability to release molecules for osteoinudction. In vivo assessment confirmed biocompatibility, showed

    The purpose of this study was to present a surgical technique of open reduction and internal fixation of displaced intra-articular calcaneal fractures with 3 AO mini-fragment plates and to evaluate the clinical and radiological outcome of a consecutive group of patients after a mean follow-up of 41.7 months. A series of 54 patients (16 women and 38 men) with 62 calcaneal fractures were treated over a period of 6.5 years. Forty-five patients with 50 calcaneal fractures were completely clinically and radiologically followed up. Clinical follow-up included assessment of range of motion, pain according to a visual analogue scale, the American Orthopaedic Foot and Ankle Society hindfoot score, and the short-form 36 health survey. Radiological follow-up included plain axial and lateral radiographs and measurement of the Böhler's angle and Gissane's angle. Independent Student's t test and paired Student's t test were used alongside the chi-square test to compare clinical and radiological data and score values between different groups of patients. Eleven patients showed breakage of the osteosynthesis material during the healing process and 2 patients sustained deep wound infection requiring revision surgery. At the final follow-up all fractures had healed. The average range of motion was supination 26.4° (range 0° to 50°; SD 11.6°), pronation 15.4° (range 0° to 30°; SD 6.4°), dorsal extension 14.3° (range -10° to 30°; SD 8.0°), and plantarflexion 39.6° (range 20° to 65°; SD 11.7°). Patients with OTA type C4 fractures achieved significantly lower supination (p fracture types. The mean visual analog scale pain score was 3.6 (range 0 to 8; SD 2.3) points, average American Orthopaedic Foot and Ankle Society hindfoot score was 70.8 (range 33 to 100; SD 17.1) points, and the mean short-form 36 score was 60.98 (range 22.9 to 93.0; SD 18.4) points. The mean postoperative Böhler's angle was 28.9° (range 8° to 38°; SD 7.1°), which decreased to 23.6° (range 4

    Full Text Available Abstract Osteogenesis imperfecta is a genetic disorder characterized by increased susceptibility to fractures and vascular injuries due to connective tissue fragility. In this case report, we present a patient with osteogenesis imperfecta type I who sustained a transverse fracture of the right acetabulum while transferring from bed to chair. The fracture was repaired through an ilioinguinal approach. During the surgery, an iatrogenic injury to the femoral artery and vein occurred. This intraoperative complication was salvaged by immediate vascular repair. We discuss the possible causes of iatrogenic vascular injuries in patients with osteogenesis imperfecta. Orthopaedic surgeons should be aware of this potentially devastating complication in this particular patient cohort.

    To demonstrate the feasibility of an integer programming model to assist in pre-operative planning for open reduction and internal fixation of a distal humerus fracture. We describe an integer programming model based on the objective of maximizing the reward for screws placed while satisfying the requirements for sound internal fixation. The model maximizes the number of bicortical screws placed while avoiding screw collision and favoring screws of greater length that cross multiple fracture planes. The model was tested on three types of total articular fractures of the distal humerus. Solutions were generated using 5, 9, 21 and 33 possible screw orientations per hole. Solutions generated using 33 possible screw orientations per hole and five screw lengths resulted in the most clinically relevant fixation plan and required the calculation of 1,191,975 pairs of screws that resulted in collision. At this level of complexity, the pre-processor took 104 seconds to generate the constraints for the solver, and a solution was generated in under one minute in all three cases. Despite the large size of this problem, it can be solved in a reasonable amount of time, making use of the model practical in pre-surgical planning.

Nonunion occurred in 6 (5.08% patients, of which 4 were with open fractures (2 Gustilo type IIIB, 1 Gustilo type IIIA, 1 Gustilo type II and 2 with the segment fractures. Compartment syndrome was observed in 1 (0.85% patient with closed fracture. Malunion was found in 2 (1.69% patients. Conclusion. External fixation of tibial shaft fractures is a simple and effective method to enable the safe healing of fractures, early mobilization of the patients, early weight-bearing, as well as early rehabilitation. Fixation of tibial shaft fractures was unilateral with convergent pins orientation, and there was also a possibility of compression and distraction.

    We describe a man with an acute osteochondral defect in the lateral talar dome associated with a supination-adduction-type ankle fracture. The osteochondral defect was readily visible on plain film radiographs, and magnetic resonance imaging was ordered to determine the full extent of soft-tissue and articular injury. It was discovered that the patient had a stage IV lesion of the talar dome, with complete inversion of the fragment, and rupture of the anterior talofibular and calcaneofibular lateral ankle ligaments. Furthermore, the patient experienced an oblique fracture of the medial malleolus with comminution. The talar dome lesion was surgically reduced and fixated using bioabsorbable pins. Nine months after surgery, the patient was fully recovered from his injury and had no functional limitations.

    The post polio symdrome (PPS) refers to the development of delayed neuromuscular symptoms among survivors, years after the initial presentation of acute poliomyelitis. The symptoms of PPS vary widely and include flaccid palsy, muscle weakness, scoliosis, osteoarthritis, gait disturbance, sleep apnea syndrome (SAS), dysphagia, chronic lung dysfunction, and others. We report the successful combination of peripheral nerve blocks, femoral and sciatic nerve blocks, for surgery on the lower extremity in a patient with PPS. A 51-year-old man with continuous positive airway pressure therapy for restrictive ventilatory impairment due to scoliosis and SAS as part of the PPS was scheduled for open reduction and internal fixation (OR-IF) for a right femoral condylar fracture. Respiratory function tests demonstrated a vital capacity (VC) 1.41l (41% predicted). Arterial blood gas analysis on room air was; pH 7.376, PaCO2 55.0 mmHg, and PaO2 77.9 mmHg. With the patient in the supine position, ultrasound-guided right femoral nerve block in the infra-inguinal region was performed using 1.5% mepivacaine 10 ml and 0.75% ropivacaine 5 ml, followed by sciatic nerve block in the popliteal fossa using 1.5% mepivacaine 8 ml and 0.75% ropivacaine 4 ml in the prone position. OR-IF of the fractured femoral condyle was then successfully performed with propofol under spontaneous ventilation. Postoperatively, there were no adverse events; respiratory function was adequate, and his pain was within manageable bounds. Femoral and sciatic nerve blocks are safe and effective anesthetic methods for lower extremity surgery in patients with restrictive ventilatory impairment and hypercapnia due to scoliosis and SAS as PPS.

    2018-02-01

    Background and purpose - The treatment of patients between 55 and 70 years with displaced intracapsular femoral neck fracture remains controversial. We compared internal fixation (IF), bipolar hemiarthroplasty (HA) and total hip arthroplasty (THA) in terms of mortality, reoperations and patient-reported outcome by using data from the Norwegian Hip Fracture Register. Patients and methods - We included 2,713 patients treated between 2005 and 2012. 1,111 patients were treated with IF, 1,030 with HA and 572 patients with THA. Major reoperations (defined as re-osteosynthesis, secondary arthroplasty, exchange, or removal of prosthesis components and Girdlestone procedure), patient-reported outcome measures (satisfaction, pain, and health-related quality of life (EQ5D) after 4 and 12 months), 1-year mortality, and change in treatment methods over the study period were investigated. Results - Major reoperations occurred in 27% after IF, 3.8% after HA and 2.8% after THA. 549 patients (20% of total study population) answered both questionnaires. Compared with IF, patients treated with THA were more satisfied after 4 and 12 months, reported less pain after 4 months and 12 months, had a higher EQ5D-index score after 4 months and 12 months, and EQ-VAS score after 4 months. Compared with IF, patients treated with HA were more satisfied and reported less pain after 4 months. EQ5D-index and EQ-VAS were similar. Patients treated with HA had higher 1-year mortality and had more comorbidities than both the THA and IF group. All these differences were statistically and clinically significant. Interpretation - This study showed high reoperation rate after IF and better patient-reported outcome after both THA and HA with medium follow-up. Patients selected for HA represented a frailer group than patients treated with THA or IF.

    Full Text Available BACKGROUND Open fractures which occur close to any fracture need immobilisation for the soft tissues to heal. Some open fractures are even fixed with provisional fixations to maintain the alignment of the fractures. The provisional fixation needs to be augmented with external support, which can be given by spanning external fixators across a joint. MATERIALS AND METHODS Our study consists of 38 open fractures of the lower limbs, which are of Gustilo-Anderson’s type IIIB, an MT4 of AO-ASIF soft tissue injury classification essentially requiring open wound management as well as fracture fixation. Wound lavage and debridements are carried out till the soft tissues show granulations. The position in which joint is immobilised is functional and with access to open wound for dressings and inspection without any displacement of the fracture as well as creeping granulation tissue. RESULTS All the cases in our study are maintained with functional position till soft tissue cover is achieved and provisional fixation is done with definitive fixation after soft tissue cover with skin grafting. CONCLUSION Spanning external fixators are useful in maintaining functional positions as well as augmenting the provisional fixation of the compound fractures.

    Displaced acetabular fractures should be treated surgically. Over the past decade, surgical approaches to the acetabulum and the surgical technique for repair of common fracture patterns have advanced. Excellent outcomes after repair of these injuries can be achieved. The aim of this study was to assess the medium-term results of reconstruction of acetabular fractures by using shape-memory alloy designed by the authors. This is a retrospective review conducted at a level 1 trauma centre. From October 1999 to July 2009, 19 patients with acetabular fractures were treated with our patented Ni-Ti shape-memory alloy acetabular tridimensional memory alloy-fixation system (ATMFS). The ATMFS device was cooled with ice before implantation and then warmed to 40–50°C after implantation to produce balanced axial and compression forces that would stabilise the fracture three dimensionally. Our results are as follows; according to the D’Aubigne−Postel scoring system: Fifteen cases out of 19 (79%) achieved excellent or good clinical results. In two patients, late complications included avascular necrosis of the femoral head (ANFH) associated with posterior dislocation of the hip joint two years after the operation. We also observed two cases of grade II or III ectopic ossification, with good hip function, and one case of traumatic arthritis. In conclusion, these results demonstrate the effectiveness of the ATMFS device for the management of acetabular fracture. The device provides continuous compression of the fracture with minimal disruption to the local blood supply. PMID:20012433

    The open reduction with internal fixation is an effective approach for treatment of avulsion fracture of posterior cruciate ligament. The previously used internal fixation materials including hollow screws, absorbable screw, tension bands and sutures have great defects such as insufficient fixation strength, susceptibility to re-fracture, etc. Stellate steel plate is novel material for internal fixation which has unique gear-like structure design. We used stellate steel plate for treatment of displaced avulsion fractures of posterior cruciate ligament in this study. 14 patients (9 men, 5 women; aged, 19-35 years; mean age, 28 years) with displaced avulsion fractures of the tibial insertion of the posterior cruciate ligament were retrospectively analyzed between June 2009 and June 2011. The mean duration from injury to the operation was 8.3 days (range 6-15 days). All the patients were treated with open reduction and internal fixation of a stellate steel plate (DePuy, Raynham, MA 02767, USA). The Lysholm-Tegner knee function score criteria were used to analyze results. The mean followup was 24.6 months (range 18-32 months). After 6 months, all the fractures healed and knee joint activity was normal, with no knee stiffness or instability. The Lysholm-Tegner scores were 97.1 ± 1.7 points at the final followup. Owing to its unique gear structure, the stellate steel plate design can effectively fix an avulsion fracture block and it is a simple operation with short postoperative rehabilitation time and firm fixation.

    Ankle fractures are complex injuries with variable prognoses that depend upon many factors. The aim of the treatment is to restore the ankle joint biomechanical stability with maximum range of motion. Most ankle fractures are fibular fractures, which have a typical oblique fracture line in the distal fibula located in the area of the tibiofibular syndesmosis. The aim of this study was to simulate numerically several fixation techniques of the distal fibular fractures, evaluate their stability, determine their impact on surrounding tissue load, and correlate the results to clinical treatment experience. The following three models of fibular fracture fixation were used: (a) plate fixation with three screws attached above/below and lag screws, (b) plate fixation with two screws attached above/below and lag screws, and (c) three lag screws only. All three fracture fixation models were analyzed according to their use in both healthy physiological bone and osteoporotic bone tissue. Based on the results of Finite Element Analysis for these simulations, we found that the most appropriate fixation method for Weber-B1 fibular fractures was an unlocked plate fixation using six screws and lag screws, both in patients with physiological and osteoporotic bone tissue. Conversely, the least appropriate fixation method was an unlocked plate fixation with four screws and lag screws. Although this fixation method reduces the stress on patients during surgery, it greatly increased loading on the bone and, thus, the risk of fixation failure. The final fixation model with three lag screws only was found to be appropriate only for very limited indications.

    : A previous hip fracture more than doubles the risk of a contralateral hip fracture. Pharmacologic and environmental interventions to prevent hip fracture have documented poor compliance. The purpose of this study was to examine the cost-effectiveness of prophylactic fixation of the uninjured hip to prevent contralateral hip fracture. : A Markov state-transition model was used to evaluate the cost and quality-adjusted life-years (QALYs) for unilateral fixation of hip fracture alone (including internal fixation or arthroplasty) compared with unilateral fixation and contralateral prophylactic hip fixation performed at the time of hip fracture or unilateral fixation and bilateral hip pad protection. Prophylactic fixation involved placement of a cephalomedullary nail in the uninjured hip and was initially assumed to have a relative risk of a contralateral fracture of 1%. Health states included good health, surgery-related complications requiring a second operation (infection, osteonecrosis, nonunion, and malunion), fracture of the uninjured hip, and death. The primary outcome measure was the incremental cost-effectiveness ratio estimated as cost per QALY gained in 2006 US dollars with incremental cost-effectiveness ratios below $50,000 per QALY gained considered cost-effective. Sensitivity analyses evaluated the impact of patient age, annual mortality and complication rates, intervention effectiveness, utilities, and costs on the value of prophylactic fixation. : In the baseline analysis, in a 79-year-old woman, prophylactic fixation was not found to be cost-effective (incremental cost-effectiveness ratio = $142,795/QALY). However, prophylactic fixation was found to be a cost-effective method to prevent contralateral hip fracture in: 1) women 71 to 75 years old who had 30% greater relative risk for a contralateral fracture; and 2) women younger than age 70 years. Cost-effectiveness was greater when the additional costs of prophylaxis were less than $6000. However, for

    To assess mid-term outcome of screw and wire fixation for Lisfranc fracture dislocations to determine the risk factors of post-traumatic arthritis. 15 men and 4 women aged 21 to 58 (mean, 41) years with Lisfranc fractures underwent open/ closed reduction and internal fixation (using screw and wire). Fractures were classified as homolateral (n=7), isolated (n=7), and divergent (n=5). Six patients had open fractures; 8 patients injured 5 tarsometatarsal joints; and 6 patients had pure ligamentous injury. Outcome (pain, function, and cosmesis) was assessed using the Maryland foot score and the American Orthopedic Foot and Ankle Society (AOFAS) score. Weight-bearing radiographs were evaluated for non-union, subluxation, malalignment, and post-traumatic arthritis. Patients were followed up for 24 to 40 (mean, 30) months. Patients with anatomic reduction (n=14) achieved higher mean AOFAS foot score (79.3 vs. 67.5, p=0.0007) and Maryland foot score (80.4 vs. 69.4, p=0.0009) than did patients with non-anatomic reduction (n=5). Post-traumatic arthritis occurred significantly more often in patients with non-anatomic than anatomic reduction (3/5 vs. 1/14, p=0.037). Four patients developed post-traumatic arthritis, one of whom also developed lateral subluxation after implant removal. Two patients developed flat foot. Two patients had severe symptoms that limited function, one of whom underwent an arthrodesis. Two patients with compound fractures developed superficial infections. Three patients had broken screws. Anatomic reduction is the main predictor of outcome in patients with Lisfranc fracture dislocations.

    Fracture fixation of the medial malleolus in rotationally unstable ankle fractures typically results in healing with current fixation methods. However, when failure occurs, pullout of the screws from tension, compression, and rotational forces is predictable. We sought to biomechanically test a relatively new technique of bicortical screw fixation for medial malleoli fractures. Also, the AO group recommends tension-band fixation of small avulsion type fractures of the medial malleolus that are unacceptable for screw fixation. A well-documented complication of this technique is prominent symptomatic implants and secondary surgery for implant removal. Replacing stainless steel 18-gauge wire with FiberWire suture could theoretically decrease symptomatic implants. Therefore, a second goal was to biomechanically compare these 2 tension-band constructs. Using a tibial Sawbones model, 2 bicortical screws were compared with 2 unicortical cancellous screws on a servohydraulic test frame in offset axial, transverse, and tension loading. Second, tension-band fixation using stainless steel wire was compared with FiberWire under tensile loads. Bicortical screw fixation was statistically the stiffest construct under tension loading conditions compared to unicortical screw fixation and tension-band techniques with FiberWire or stainless steel wire. In fact, unicortical screw fixation had only 10% of the stiffness as demonstrated in the bicortical technique. In a direct comparison, tension-band fixation using stainless steel wire was statistically stiffer than the FiberWire construct. Copyright 2011, SLACK Incorporated.

    Periprosthetic fracture and infection are both challenges following hip arthroplasty. We report the case of an 87 year old female who underwent open reduction and internal fixation of a periprosthetic femoral fracture. Her post-operative course was complicated by infection with Clostridium perfringens. Early aggressive antibiotic treatment and surgical debridement were successful, and allowed retention of the original components.

    Beside biomaterials, Laser phototherapy has shown positive effects as auxiliary therapy in bone repair process, especially when involving large bone losses. The aim of this histological study was to evaluate, by light microscopy, the influence of laser phototherapy on the repair of complete tibial fractures in rabbits treated or not with semi-rigid internal fixation and Mineral Trioxide Aggregate - MTA graft. Twelve Rabbits were randomly divided into four groups with three animals each. After general anesthesia, complete fractures were created in one tibia with a carborundum disk. All animals (groups I-IV) had the fracture stabilized with semi-rigid fixation (wire osteosynthesis - WO). Group I was routinely fixed with WO; groups II and IV fracture was filled by blood clot and MTA implant. In Groups III and IV fracture was filled by blood clot and further irradiated with laser (λ780 nm, 70 mW, CW, Φ = 0.04 cm2, 20.4 J/cm2, per session, t = 300s, 142.8 J/cm2 per treatment). The phototherapy protocol was applied immediately after the surgery and repeated each 48 hours during 15 days. Animal death occurred on the 30th postoperative day. After removal of the specimens, the samples were routinely processed, stained with HE and evaluated by light microscopy. Histologically, the group treated with MTA graft and irradiated with laser showed the fracture filled by a more organized and mature trabecular bone, when compared with all other groups. From the results of the present study, it may be concluded that the association of Laser phototherapy + MTA graft in fractures treated with WO improved bone repair when compared with fractures treated only with WO.

    The aim of the present study was to examine biomechanically 5 different construct combinations for fixation of ipsilateral intertrochanteric and femoral shaft fractures. Twenty-five fresh-frozen adult human femora (age range = 58-91 years, average age = 75.4 years) were tested in physiological bending and in torsion to characterize initial bending and torsional stiffness and stiffness following fixation of combined intertrochanteric and femoral shaft fractures. Five fracture fixation device constructs were assessed-construct A: long dynamic hip screw (long DHS); construct B: reconstruction nail; construct C: DHS plus low-contact dynamic compression plate; construct D: DHS plus retrograde intramedullary nail; and construct E: long intramedullary hip screw. Axial stiffness, torsional stiffness, and axial load-to-failure were the main measurements recorded. There were no differences between constructs in terms of axial stiffness (P = 0.41), external rotation stiffness (P = 0.13), and axial load-to-failure (P = 0.16). However, there was a borderline statistically significant difference in internal rotation stiffness between the constructs (P = 0.048). Specifically, construct C was significantly stiffer than construct E (P = 0.04). All constructs showed no statistical differences when compared with one another, with the exception of construct E, which provided the least torsional stiffness. However, the current in vitro model did not simulate fracture healing or support offered by soft tissues, both of which would affect the stiffness and load-to-failure levels reached.

    Recent advances in external fixation technique and pin design have sought to minimize complications such as pin site infection and premature removal of the external fixator. Although newer forms of internal fixation have gained popularity, external fixation may still have a role in managing pediatric femoral shaft fractures. We sought to assess the time to healing, limb alignment, and complications observed in a cohort of pediatric patients with closed femoral shaft fractures who were treated with external fixation. Over a 15-year period, one surgeon treated 289 pediatric patients with femur fractures, 31 (11%) of whom received an external fixator. The general indications for use of an external fixator during the period in question included length-unstable fractures, metadiaphyseal location, refracture, and pathologic fracture. Six patients (19%) had inadequate followup data and four patients (13%) were treated with a combination of flexible intramedullary nails and external fixation, leaving 21 patients for analysis. Mean age at injury was 10 years (range, 6-15 years) and followup averaged 22 months (range, 5-45 months) after removal of the fixator. Radiographs were examined for alignment and limb length discrepancy. Complications were recorded from a chart review. Mean time in the fixator was 17 weeks (range, 9-24 weeks). One patient sustained a refracture and one patient with an isolated femur fracture had a leg length discrepancy > 2 cm. There were no pin site infections requiring intravenous antibiotics or additional surgery. One patient with Blount disease and previous tibial osteotomy developed transient peroneal nerve palsy. Despite improvements in pin design and predictable fracture healing, complications such as refracture and leg length discrepancy after external fixation of pediatric femoral shaft fractures can occur. However, external fixation remains a viable alternative for certain fractures such as length-unstable fractures, metadiaphyseal

    Full Text Available Background The value of external fixation in complex hand injuries is well established. Expenses and technical difficulties of commercial mini external fixator sets have led to the innovation of handmade external fixators. These fixators are used as versatile facilities to treat certain hand fractures. Usually, these structures are made by k-wires crossed filled with cement plastic tube. However, these fixators have multiple deficiencies that should be addressed. Objectives In this study, we described in detail the surgical technique of a handmade concrete like mini external fixator and report its clinical use and results. Methods Our handmade external fixator was applied for 52 patients with 56 fractures. Only 5% of the fractures were closed, non-comminuted extra-articular, and the other 51 fractures were more complex injuries. The mean follow up time was 9.3 months. At the end of the follow up, radiologic and functional assessment (DASH: Disability of arm, shoulder and hand and TAM: Total active motion was evaluated. Results All 56 fractures were united completely. None of the cases experienced pin loosening or reduction loss. Of the fractures, 8.9% malunited due to fracture complexity. The mean dash score was 3.76. TAM was excellent in 45% of the fractures; it was good in 7% and fair in 4%. Conclusions This type of handmade external fixator is simple, lightweight, and cheap. Furthermore, all implements are readily available in most operating fields. The probability of loosening has been greatly diminished because of the concrete like structure. Easy and fast assembly and good clinical and functional results are the other advantages of this technique. Due to the less complication and benefits, this technique could be used for many phalangeal and metacarpal fractures with confidence.

    The aim of this paper is to report the outcomes and any complications with arthroscopic bioabsorbable nail fixation of tibial eminence fractures in skeletally immature patients. We retrospectively reviewed all surgically treated tibial eminence fractures treated by a single surgeon and seven patients were identified with a minimum 2-year follow-up. Mean deficits of flexion and extension were minimal. Satisfactory Tegner levels, Lysholm knee scores, and International Knee Documentation Committee subjective scores were reported. Arthroscopic fixation of tibial eminence fractures with bioabsorbable nails yields satisfactory outcomes for this uncommon injury and obviates the need for future hardware removal.

    Full Text Available Abstract Background Fractures of the distal radius represent the most common fracture in elderly patients, and often indicate the onset of symptomatic osteoporosis. A variety of treatment options is available, including closed reduction and plaster casting, K-wire-stabilization, external fixation and open reduction and internal fixation (ORIF with volar locked plating. The latter is widely promoted by clinicians and hardware manufacturers. Closed reduction and cast stabilization for six weeks is a simple, convenient, and ubiquitously available intervention. In contrast, ORIF requires hospitalization, but allows for functional rehabilitation. Given the lack of randomized controlled trials, it remains unclear whether ORIF leads to better functional outcomes one year after injury than closed reduction and casting. Methods/Design ORCHID (Open reduction and internal fixation versus casting for highly comminuted intra-articular fractures of the distal radius is a pragmatic, randomized, multi-center, clinical trial with two parallel treatment arms. It is planned to include 504 patients in 15 participating centers throughout Germany over a three-year period. Patients are allocated by a central web-based randomization tool. The primary objective is to determine differences in the Short Form 36 (SF-36 Physical Component Score (PCS between volar locked plating and closed reduction and casting of intraarticular, comminuted distal radius fractures in patients > 65 years of age one year after the fracture. Secondary outcomes include differences in other SF-36 dimensions, the EuroQol-5D questionnaire, the Disability of the Arm, Shoulder, and Hand (DASH instrument. Also, the range of motion in the affected wrist, activities of daily living, complications (including secondary ORIF and revision surgery, as well as serious adverse events will be assessed.

However, whether intramedullary or extramedullary fixation is the primary treatment for subtrochanteric femur fractures in adults remains debatable.Level of evidence: Meta-analyses of prospective studies, level I.Materials and methods: The Cochrane library, Embase, Google Scholar, and PubMed databases were searched separately for all relevant studies published before January 1, 2015. No language restriction was applied. Prospective randomized controlled trials that compared intramedullary or extramedullary internal fixation to repair subtrochanteric femur fractures in adults were included. We determined intraoperative data, postoperative complications, fracture fixation complications, wound infection, hospital stay days, and final outcome measures to assess the relative effects of different internal fixation methods for the treatment of subtrochanteric femur fractures in adults.Results: Six studies were included in our meta-analysis.

    Internal fixation of the os calcis is often complicated by prolonged soft tissue management and posterior facet disruption. An ideal calcaneal construct would include minimal hardware prominence, sturdy posterior facet fixation and nominal soft tissue disruption. The purpose of this study was to develop such a construct and provide a biomechanical analysis comparing our technique to a standard internal fixation technique. Twenty fresh-frozen cadaver calcanei were used to create a reproducible Sanders type-IIB calcaneal fracture pattern. One calcaneus of each pair was randomly selected to be fixed using our compressive headless screw technique. The contralateral matched calcaneus was fixed with a nonlocking calcaneal plate in a traditional fashion. Each calcaneus was cyclically loaded at a frequency of 1 Hz for 4000 cycles using an increasing force from 250 N to 1000 N. An Optotrak motion capturing system was used to detect relative motion of the three fracture fragments at eight different points along the fracture lines. Horizontal separation and vertical displacement at the fracture lines was recorded, as well as relative rotation at the primary fracture line. When the data were averaged, there was more horizontal displacement at the primary fracture line of the plate and screw construct compared to the headless screw construct. The headless screw construct also had less vertical displacement at the primary fracture line at every load. On average those fractures fixed with the headless screw technique had less rotation than those fixed with the side plate technique. A new headless screw technique for calcaneus fracture fixation was shown to provide stability as good as, or better than, a standard side plating technique under the axial loading conditions of our model. Although further testing is needed, the stability of the proposed technique is similar to that typically provided by intramedullary fixation. This fixation technique provides a biomechanically stable

    Acetabular fractures can be classified into 5 simple and 5 associated fracture patterns. A significant amount of variation and complexity exists in these fractures patterns. Fractures of the posterior wall are the most common acetabular fractures. Comminution of the quadrilateral plate adds to fracture instability, and more rigid and stable internal fixation is mandatory. The goal of this study was to assess the results of reconstruction of comminuted posterior wall fractures of the acetabulum associated with quadrilateral plate fractures using the tension band technique. Twelve patients (9 men and 3 women) were included in the study. Mean patient age was 38.6 years (range, 24-47 years). Minimum follow-up was more than 2 years postoperatively. Reconstruction of the fracture included anatomic reduction of the fracture and fixation with a buttress plate for the posterior column and a prebent one-third tubular plate for the quadrilateral plate fracture. Clinical results were excellent in 58% of patients and good in 17% of patients. Radiologic results were excellent in 50% of patients and good in 17% of patients. Radiologically, based on the fracture gap postoperatively, 8 (66%) patients showed anatomic reduction, 2 (17%) showed good reduction, and 2 (17%) showed poor reduction. The study confirms that this method of reconstruction facilitates accurate and firm reduction of displaced posterior wall fractures of the acetabulum. Copyright 2013, SLACK Incorporated.

    There is an increasing incidence of fragility fractures of the ankle in the elderly population. The open reduction and internal fixation of these fractures is challenging, due to reduced bone stock quality as a result of osteoporosis. Biomechanical studies have shown contradicting results using reinforced constructions in the fixation of fibular fractures. We therefore performed a meta-analysis of biomechanical studies on reinforced fixation of distal fibular fractures. A literature search was conducted utilizing three online databases considering biomechanical testing of different fixation techniques of distal fibular fractures. A meta-analysis was performed on two biomechanical outcome measures; torsional stiffness and torque to failure. In a total number of 13 studies 8 different reinforcement techniques were identified. Of these studies, six compared locked lateral plating with conventional lateral plating. There were no statistically significant differences between the locking and non-locking lateral plate for torque to failure or torsional stiffness. Locked plating strength was independent from bone mineral density in four studies. An antiglide plate proved to be biomechanically superior compared to a lateral plate in one study and to a locked plate in another. Locked lateral plates are not biomechanically superior to conventional lateral plates. However the strength of locked plating may be independent of bone mineral density and could make this technique more suitable in the fixation of severe osteoporotic fractures.

    Full Text Available Background: The open reduction with internal fixation is an effective approach for treatment of avulsion fracture of posterior cruciate ligament. The previously used internal fixation materials including hollow screws, absorbable screw, tension bands and sutures have great defects such as insufficient fixation strength, susceptibility to re-fracture, etc. Stellate steel plate is novel material for internal fixation which has unique gear-like structure design. We used stellate steel plate for treatment of displaced avulsion fractures of posterior cruciate ligament in this study. Materials and Methods: 14 patients (9 men, 5 women; aged, 19-35 years; mean age, 28 years with displaced avulsion fractures of the tibial insertion of the posterior cruciate ligament were retrospectively analyzed between June 2009 and June 2011. The mean duration from injury to the operation was 8.3 days (range 6-15 days. All the patients were treated with open reduction and internal fixation of a stellate steel plate (DePuy, Raynham, MA 02767, USA. The Lysholm-Tegner knee function score criteria were used to analyze results. Results: The mean followup was 24.6 months (range 18-32 months. After 6 months, all the fractures healed and knee joint activity was normal, with no knee stiffness or instability. The Lysholm-Tegner scores were 97.1 ± 1.7 points at the final followup. Conclusion: Owing to its unique gear structure, the stellate steel plate design can effectively fix an avulsion fracture block and it is a simple operation with short postoperative rehabilitation time and firm fixation.

    Full Text Available Background: Management of high velocity trauma is a challenging problem because of morbidity of trauma and sometime residual problems of failure of proper healing of fractures with the restriction of movements of knee, shortening, and added risk of compartment syndrome in the proximal tibia fracture. There is always risk of post-operative infection and infected non-union in extensive open surgical procedure and internal fixation. Hence, there is always look out for the middle path procedure for a solution to the above said problems with the added advantage of less hospital stay and early return to work by minimal invasive procedure and stabilization of fracture reduction by multiple K-wire fixation with a frame applied externally. Stabilization of fracture with reduced pain allows early movements of neighbouring joint knee and ankle; hence, reduces the chances of fracture diseases. With this we have been stimulated to take-up the study of managing the proximal tibia fracture by mini external fixator. Aim: The aim of this study was to manage proximal tibia fractures by mini external fixator and evaluate the results and efficacy of this method. Material and Method: A total of 30 patients having proximal tibial fractures admitted at our center between 2008 and 2010 were taken and the procedure carried out was closed manipulative reduction and stabilization with mini external fixator. All acute proximal tibia fractures including tibial plateau fractures above 17 years of age of either sex were included in the study. Fracture more than 3 weeks old were excluded from the study. Result: Out of 30 cases 13 were excellent, 14 cases good, and 3 showed fair. It was found that type 5 and 6 of Schatzker′s classification have lesser outcome type of fractures Conclusion: We have found that management of the proximal tibia fractures by mini external fixation method has a better outcome.

    In the treatment of avulsion fractures of the posterior calcaneal tuberosity, open reduction and internal fixation are prone to several complications. We describe a new treatment using an Ilizarov external fixator, which can minimise the complications and achieve sufficient stability of the displaced fragment. A 55-year-old woman sustained an avulsion fracture of the calcaneus. Examination revealed the development of bruising with extremely taut skin over the posterior prominence of the displaced bone. Radiographs demonstrated grossly proximal displacement of the tuberosity fragment. Surgery was exclusively percutaneous using an Ilizarov external fixator. The displaced fragment was adequately reduced and stabilised. Progressive weight bearing in the equinus position was initiated at the third week after surgery and the external fixator was removed at the seventh week. There was no skin necrosis or loss of reduction while the fixator was maintained. Postoperative follow-up for 2 years revealed full recovery. Major postoperative complications after conventional open reduction and internal fixation include skin necrosis, skin irritation by metal implants and re-displacement of the reduced fragment. Our method of using an external fixator may decrease the incidence of these three complications. Skin incision and the risk of skin necrosis are inevitable during internal fixation. On the other hand, the use of an external fixator reduces or eliminates skin necrosis, as it is applied percutaneously for reduction and stabilisation of the fragment. External fixation is mostly recommended in cases of poor vascularity or bruising. In addition, skin irritation can be avoided upon removal of the external fixator. Re-displacement occurs occasionally as a serious complication in lag screw fixation, particularly in cases with poor purchase of the osteoporotic bone. Tension band wiring and application of an Ilizarov external fixator in avulsion fractures of the calcaneus can

    The tibia is the most commonly fractured long bone. Although the goals of fracture management are straightforward, methods for achieving anatomical alignment and stable fixation are limited. Type of management depends on fracture pattern, local soft-tissue involvement, and systemic patient factors. Tibial shaft fractures with concomitant fibula fractures, particularly those at the same level, may be difficult to manage because of their inherent instability. Typically, management of lower extremity fractures is focused on the tibia fixation, and the associated fibula fracture is managed without fixation. In this article, we describe a novel technique for intramedullary fixation of the fibula, using a humeral guide wire as an adjunct to tibia fixation in the setting of tibial shaft fracture. This technique aids in determining length, alignment, and rotation of the tibia fracture and may help support the lower extremity as whole by stabilizing the lateral column. In addition, this technique can be used to help maintain reduction of the fibula when there is concern about the soft tissues of the lower extremity secondary to swelling or injury. Our clinical case series demonstrates the safety, effectiveness, and cost-sensitivity of this technique in managing select concurrent fractures of the tibia and fibula.

    Internal fixation is a mechanism purposed to maintain and protect the reduction of a fracture. Understanding of the fixation stability is necessary to determine parameters influence the mechanical stability and the risk of implant failure. A static structural analysis on a bone fracture fixation was developed to simulate and analyse the biomechanics of a diaphysis shaft fracture with a compression plate and conventional screws. This study aims to determine a critical area of the implant to be fractured based on different implant material and angle of fracture (i.e. 0°, 30° and 45°). Several factors were shown to influence stability to implant after surgical. The stainless steel, (S. S) and Titanium, (Ti) screws experienced the highest stress at 30° fracture angle. The fracture angle had a most significant effect on the conventional screw as compared to the compression plate. The stress was significantly higher in S.S material as compared to Ti material, with concentrated on the 4th screw for all range of fracture angle. It was also noted that the screws closest to the intense concentration stress areas on the compression plate experienced increasing amounts of stress. The highest was observed at the screw thread-head junction.

    The use of metal in fracture fixation has demonstrated unrivalled success for many years owing to its high stiffness, strength, biological toleration and overall reliable function. The most prominent materials used are electropolished stainless steel and commercially pure titanium, along with the more recent emergence of titanium alloys. Despite the many differences between electropolished stainless steel and titanium, both materials provide a relatively predictable clinical outcome, and offer similar success for fulfilling the main biomechanical and biological requirements of fracture fixation despite distinctive differences in implant properties and biological responses. This article explores these differences by highlighting the limitations and advantages of both materials, and addresses how this translates to clinical success.

    2017-04-01

    Full Text Available BACKGROUND External Fixation (EF and Open Reduction and Internal Fixation (ORIF have been the traditional surgical modalities for unstable distal radius fractures. The Locking Compression Plates (LCP acting as “internal external fixators” are particularly valuable in difficult situations of fractures. We undertook a study to evaluate the outcome of unstable distal radius fractures treated with ORIF with LCP versus those treated by ligamentotaxis with external fixators. MATERIALS AND METHODS A comparative study was carried out in a tertiary care centre with 30 cases of unstable distal radius fractures (15 cases in each group. In one group, open reduction and internal fixation with distal radius volar locking compression plate was carried out and in the other group ligamentotaxis with external fixator was done. The patients were treated and followed up over a period of one and a half year between June 2011 to November 2012. The fractures were classified according to AO classification (Arbeitsgemeinschaft für Osteosynthesefragen: German for “Association for the Study of Internal Fixation” or AO. The functional results were evaluated at the end of 6 months according to Demerit point system of Gartland and Werley modified by Sarmiento (1975 and the anatomical results as per Lindstrom criteria (1959 modified by Sarmiento (1980. RESULTS Overall 86.66% (13 cases had good-to-excellent anatomical results in external fixator group as compared to 93.33% (14 cases in LCP group. The functional outcome was excellent in 80% (12 and good in 13.33% (2 cases in external fixator group as compared to 66.66% (10 excellent and 26.66% (4 good in LCP group. CONCLUSION Both open reduction and internal fixation with locking compression plate and ligamentotaxis with external fixators are good treatment modalities for unstable distal radius fractures. However, the choice should be guided by the fracture configuration, surgeons’ experience and patient’s profile.

    Full Text Available Fractures of the horizontal surface of the distal tibia are known commonly as pylon or plafond fractures, and represent 1-5% of lower extremity fractures, 7-10% of all tibial fractures. The protocol consisted of immediate (within eight to 24 hours open reduction and internal fixation of the fibula, using a fibular plate or one third tubular plate and application of an external fixator spanning the ankle joint. In the second stage, the treatment of proximal and distal tibial fractures with close reduction and MIPPO technique can preserve soft tissue, simplify operative procedure and decrease wound, obtain rigid internal fixation and guarantee early function exercises of ankle joint. In this study we evaluated 22 patients treated in Clinical Emergency Hospital Constanta between April 2012 - July 2013 diagnosed with multifragmentary fractures of the distal tibia. This study evaluates the treatment of complex fractures of distal tibia with locked plate after external fixation. There were 17 males and 5 females of mean age 51,7 years (31-68. The mean follow-up period was 14 weeks. (Ranging from 9-16 weeks. All patients were fully weight bearing at 16 weeks (ranging 9-16 weeks showing radiological union. There were no cases of failures of fixation, or rotational misalignment. No significant complication was observed in our patients. MIPO is an effective method of treatment for distal tibial fractures, reduce surgical trauma and maintain a more biologically favorable environment for fracture healing, reducing risks of infection and nonunion.

    Though the date at which an orthopaedic implant was first used cannot be ascertained with any certainty, the fixation of bone fracture using an iron wire was reported for the first time in a French manuscript in 1775. The first techniques of operative fracture treatment were developed at the end of the 18th and in the beginning of the 19th centuries. The use of cerclage wires to fix fractures was the most frequent fixation at this time. The French Berenger-Feraud (1832-1900) had written the first book on internal fixation. However internal fixation of fractures could not become a practical method before Lister had ensured the safety of open reduction and internal fixation in the treatment of fractures. Lister is not only the father of asepsis; he also used metal wires to fix even closed fractures. The first internal fixation by means of a plate and screws was described by Carl Hansmann in 1858 in Hamburg. Nevertheless, Arbuthnot Lane (1892) and Albin Lambotte (1905) are considered to be the founders of this method, which was further developed by Sherman in the first part of the 20th century.

    Full Text Available Intramedullary nailing of metaphyseal and segmental tibia fractures can be technically challenging for a variety of reasons. Restoring length, alignment and rotation of the injured limb requires careful preoperative planning and meticulous attention to surgical technique, while avoiding common pitfalls. Understanding the deforming forces on the fracture segments and normal tibial osteology provides a background for recognizing the most common pitfalls when nailing these fractures. Many adjuncts for obtaining and maintaining fracture reduction while nailing have been described, including extended positioning, use of the femoral distractor, blocking screws, and provisional plating. We discuss these techniques as well as the role of intramedullary fixation for treating metaphyseal fractures with articular extension. The purpose of this paper is to describe the background and technique for a variety of operative tips and tricks to facilitate intramedullary nailing of metaphyseal and segmental tibia fractures.

    The aim of the present study was to evaluate the stability of the figure of eight plus circular wiring fixation technique compared with four common internal fixation techniques and to provide experimental data for the selection of internal fixation techniques clinically. A total of 20 fresh cadaveric elbow joints were used as transverse, oblique and comminuted olecranon fracture models. Five techniques of internal fixation were investigated: circular wiring, figure of eight wiring, circular plus figure of eight wiring, Kirschner wire (K-wire) and screw fixation. The elbow joints were flexed at 90°. The fixation performance was tested using a high-precision displacement sensor. Displacement-load curves revealed that the strength of internal fixation was weakest when using circular wiring alone and that circular wiring plus figure of eight wiring fixation was stronger than that of figure of eight wiring or screw fixation. The difference was statistically significant (Pwiring plus figure of eight wiring fixation and K-wire fixation in the transverse and oblique fracture models (P>0.05). However, figure of eight plus circular wiring fixation was superior to K-wire fixation in the comminuted fracture model, with a tensile force of 67.42±2.17 vs. 58.52±2.17 N, respectively (Pwiring plus figure of eight wiring fixation recovered and 108 were included in the follow-up for an average of 12 months. The rate of excellent/fairly good recovery was 98.10%. Due to its reliability, simple surgery, lower invasiveness and lower cost, figure of eight plus circular wiring fixation is an ideal choice for the internal fixation of olecranon fractures, particularly comminuted fractures, compared with circular wiring, figure of eight wiring or screw fixation.

Milder complications such as soft tissue pin tract infection developed in 13 (19.12% patients, infection of the open fracture wound soft tissue was observed in four (5.88% patients. Conclusion. Basic principles in the treatment of open lower leg fractures in this study are thorough primary open fracture wound treatment followed by the delayed wound closure, stable fracture fixation using unilateral external skeletal device, proper antibiotic treatment and tetanus prophylaxis. The results correlate with similar studies. [Projekat Ministarstva nauke Republike Srbije, br. III 41017: Virtual Human Osteoarticular System and its Application in Preclinical and Clinical Practice

  9. Biomechanical considerations in intramedullary fixation of lower-extremity fracture.

    Since Gerhard Kuntscher's first cloverleaf design was introduced in the early 1940s, intramedullary nail geometry has become increasingly complex. Many design changes have been introduced, and these have had profound effects upon the mechanical performance of intramedullary devices, making them more versatile. The subset of long-bone fractures amenable to intramedullary fixation is expanding, largely because of these advancements in nail design. Selection of the appropriate nail and bone-nail construct for each fracture configuration requires a knowledge of basic biomechanical principles behind nail design and the implant-host interface. Appropriate clinical application of this knowledge not only ensures the best possible intramedullary fixation of long-bone fractures, but it also aids in avoiding some of the complications that may occur.

    PURPOSE OF THE STUDY Closed reduction and percutaneous fixation of nondisplaced talar neck fractures have been applied by some authors. The aim of this paper is to assess the results and complications of this minimally invasive technique. MATERIAL AND METHODS In the period from 2009 to 2014, twenty-one patients with a talar neck fracture were observed after closed reduction and percutaneous screw fixation in the Traumatological Hospital in Brno. The mean age of the patients was 38 years (range 18-56 years). The mechanism of injury was a motor vehicle accident in 11 cases, a fall from height in six cases, a sports injury in 3 cases, and a fall from stairs in one case. Injuries were classified according to the Hawkins classification. Conventional preoperative 3-dimensional CT scans of the fractures were analysed. Under the guidance of C-arm fluoroscopy, Kirscher wires were used for closed reduction and temporary percutaneous fixation. Subsequently, 3.5 and 4.5 mm diameter cannulated screws were inserted. The outcome was evaluated on the American Orthopaedic Foot and Ankle Society (AOFAS) scoring scale. RESULTS The average follow-up was 32 months (21-42 months). The average healing time was 15.5 weeks (13-19 weeks). The average AOFAS score was 82.3 points (69-96 points). 75% of patients with type I injury achieved excellent results and 72% of patients with type II injury achieved excellent or good results. None of the patients developed wound complications. Two patients developed partial avascular necrosis and three patients subtalar traumatic arthritis after surgery. DISCUSSION Talar neck fractures are relatively uncommon fractures. Most of the published studies are small. Tenuous blood supply and displaced talar neck fracture predispose to avascular necrosis of the talus. Closed reduction and percutaneous fixation can reduce the soft tissue damage and disturbance to the blood supply. CONCLUSIONS Preoperative 3D CT scans, early surgery, anatomic articular surface

    Intramedullary (IM) nailing is a well-accepted treatment for distal third tibia fractures in combination with injury to the fibula. However, the indications for operative stabilisation of the fibula remain controversial. The authors performed a retrospective review on a consecutive series of patients who underwent intramedullary nailing of a non-comminuted distal third tibia fracture with or without fibular fixation at a Level I urban trauma centre. A review of surgical records identified 120 patients who initially were included in this study, while a total of 98 patients who met the inclusion criteria were included in the final analysis. Our results found no difference in the mean value of coronal and sagittal plane alignment in both the immediate post-operative and follow-up time periods. We also saw no statistically significant difference when comparing malalignment between patients treated with or without fibula fixation. There were no deep infections between the two groups. No significant differences were seen between the fibular fixation group and the non-fixation group. Distal screw removal due to prominence or pain was the most common reason for future surgery in both groups. These findings suggest that the addition of fibular fixation does not affect whether or not alignment is maintained in either the immediate post-operative or short-term follow-up period.

    Fifth metatarsal base fractures of the metaphyseal-diaphyseal watershed junction (Jones fracture) are commonly treated with surgical fixation in athletes. Intramedullary screw fixation remains the most utilized construct, although plantar-lateral plating is an alternative. Purpose/Hypothesis: The purpose was to compare the mechanical strength of fracture fixation between an intramedullary screw and plantar-lateral plating. The hypothesis was that plantar-lateral plate fixation would allow for more cycles and higher peak loads before failure, as well as less fracture gapping, than would an intramedullary screw in cadaveric foot specimens with simulated Jones fractures exposed to cantilever bending. Controlled laboratory study. Twelve pairs of male cadaver feet were separated into 2 groups (plate or screw) to conduct contralateral comparative testing of 2 devices with equally numbered right and left feet. For each fifth metatarsal, an osteotomy with a microsagittal saw was created to simulate a Jones fracture. The plate group underwent fixation with a 3.0-mm 4-hole low-profile titanium plate placed plantar-laterally with 3 locking screws and 1 nonlocking screw. The screw group underwent fixation with a 40- or 45-mm × 5.5-mm partially threaded solid titanium intramedullary screw. After fixation, the metatarsals were excised for biomechanical testing. Cyclic cantilever failure testing was conducted with a gradient-cycle method. Sinusoidal loading forces were applied, increasing by 5.0-pound-force increments per 10 cycles, until each specimen experienced mechanical failure of implant or bone. Failure mode, number of cycles to failure, peak failure load, gap width at the last mutual prefailure loading, and video data were recorded. Paired 2-tailed t test (α = 0.05) was used to compare groups ( P Plate fixation resulted in significantly higher mean ± SD values for cycles to failure (63.9 ± 27.0 vs 37.3 ± 36.9, P = .01) and peak failure load (159.2 ± 60.5 N vs 96.5

    Full Text Available Current surgical treatment of acetabular fractures is open reduction and internal fixation and requires a large incision resulting in considerable blood loss and a potentially long duration of recovery. We report a case of an acetabular fracture that received laparoscopic internal fixation after three-dimensional (3D modelling and printing of the acetabulum. A 43 year old male fell from a height of 3 m resulting in a right acetabulum anterior column fracture. Thin section computed tomography scanning with 0.6 mm increments and subsequent 3D reconstruction was performed, and a 3D model of the acetabulum and fracture was printed. The steel reconstruction plate was prebent in vivo and placed into the optimized position based on the 3D modelling and the optimized insert orientation and measured screw length were determined. The fracture was reduced and the plate placed laparoscopically without complications, and the patient had excellent functional recovery. Acetabular fractures are complex injuries, and while minimally invasive surgical techniques are used in many fields, they are not common for the treatment of acetabular fractures. 3D modelling is commonly used in medicine, and although 3D printing is used in some fields, it has not found widespread use in orthopedics.

  16. A Novel Technique for Closed Reduction and Fixation of Paediatric Calcaneal Fracture Dislocation Injuries

    2013-01-01

    Full Text Available Paediatric calcaneal fractures are rare injuries usually managed conservatively or with open reduction and internal fixation (ORIF. Closed reduction was previously thought to be impossible, and very few cases are reported in the literature. We report a new technique for closed reduction using Ilizarov half-rings. We report successful closed reduction and screwless fixation of an extra-articular calcaneal fracture dislocation in a 7-year-old boy. Reduction was achieved using two Ilizarov half-ring frames arranged perpendicular to each other, enabling simultaneous application of longitudinal and rotational traction. Anatomical reduction was achieved with restored angles of Bohler and Gissane. Two K-wires were the definitive fixation. Bony union with good functional outcome and minimal pain was achieved at eight-weeks follow up. ORIF of calcaneal fractures provides good functional outcome but is associated with high rates of malunion and postoperative pain. Preservation of the unique soft tissue envelope surrounding the calcaneus reduces the risk of infection. Closed reduction prevents distortion of these tissues and may lead to faster healing and mobilisation. Closed reduction and screwless fixation of paediatric calcaneal fractures is an achievable management option. Our technique has preserved the soft tissue envelope surrounding the calcaneus, has avoided retained metalwork related complications, and has resulted in a good functional outcome.

    Extra-articular distal tibia fractures include a tibial fracture line located partially or totally in the metaphyseal bone and a fibular fracture in variable areas or sometimes absent. There is no consensus in the literature on the conduct to address the fibula fracture. The main objective of this study was to assess its impact on tibial reduction and union. Fibular fixation plays a positive role in reducing tibial displacement and improving mechanical stability of the entire lesion. This study was based on the multicenter observational group of the 2009 SOFCOT symposium, i.e., 142 metaphyseal fractures of the tibia. The fibula was intact in 10 cases and fractured in 132. In the three main categories of surgical treatment for the tibia (nailing, plating, external fixation) (126 fractures), the fibular lesion was not treated in 79 cases (61%) in this series, nine were treated with intramedullary pinning, and 38 with plate and screw fixation. There was no statistical relation between the anatomic situation of the diaphysis and the anatomic type of the fibular fracture or between the anatomic type of the fibular fracture and its situation compared to the tibial fracture line. The intertubercular and neck fractures were type A1 or B1 (Pfracture with a torsional component; the medial-diaphyseal and subtubercular fractures were associated with tibial fracture lines with a simple transversal or comminution or metaphyseal-diaphyseal component (Pfracture was 4.7% at 1 year; in all these cases, fibular treatment had been conservative. All treatments combined, the tibial axes were statistically better corrected when the fibula was treated with fixation. In four of the 11 cases of axial tibial malunion, the primary fibular fixation caused or worsened them. The present clinical series provides results similar to the biomechanical studies. The consequences of fibular fixation perpetuating a tibia reduction abnormality or on the contrary the absence of fibular fixation appeared

    Galeazzi fractures traditionally are treated in long arm casts with the wrist fully supinated for 6 weeks after open reduction and internal fixation. Recent literature suggests that early motion can be permitted for a subset of Galeazzi fractures. Defining a safe postoperative protocol that allows immediate elbow motion, immediate platform weight bearing, and early wrist motion might decrease elbow morbidity, increase range of motion, and improve outcomes. A retrospective review of a prospectively collected database of 26 patients at a level I trauma center was conducted. Early motion protocol was assigned to patients who were radiographically and clinically stable after plate and screw fixation. Elbow flexion and platform weight bearing were allowed immediately; increased wrist rotation was allowed at 2-week intervals. Early motion of elbow and wrist seems to be safe during postoperative rehabilitation of repaired Galeazzi fractures. The postoperative protocol might maximize elbow and wrist range of motion.

    Full Text Available Objective To evaluate the ergotropic effect of bone cement on pedicle screw fixation in treatment of osteopo¬rotic thoracolumbar fracture. Methods Fifty-three patients with osteoporotic thoracolumbar fracture, admitted from Jun. 2013 to Dec. 2014, were included for treatment by augmentation of pedicle screw fixation with bone cement. All patients underwent pre-operative examination of bone mineral density with T-score ≤-2.5 and augmentation of pedicle screw fixation with injection of 1.5 ml bone cement in adjacent to fractured vertebra. All patients were treated with anti-osteoporosis therapy pre- and post-operation, ob¬served and recorded with basic conditions and complications. At pre-operation, one-week post-operation and last follow-up, pain vi¬sual analogue scale (VAS and neurological function score (ASIA of all patients were recorded, and the compression rats of anterior and posterior edge of fractured vertebra, and compression rats of spinal canal and Cobb angel of all patients were measured. Results All the 53 patients were successfully undergone operation in about 90-140 min with blood loss of about 150-350 ml. No spinal cord or nerve injury, dural tear and obvious leakage of bone cement and screw loosening occurred during operation. All patients were followed up for 12 to 36 months and the neurological function obviously recovered contrasted with pre-operation. X-ray and CT examination at last follow-up showed good fractures healing, good position and non-loosening of internal fixation device and non-leakage of bone cement. At one week post-operation and last follow-up, VAS, compression rats of anterior edge and posterior edge of fractured vertebra, compression rats of spinal canal and Cobb angel were significantly lower than those at pre-operation (P0.05.

    Implant breakage after the fixation of traumatic fractures is rare; however, when it occurs, it is debilitating for the patients and a challenge for surgeons. The purpose of this study was to analyze and identify the independent risk factors for implant breakage of traumatic fractures treated with plate osteosynthesis. We reviewed the medical records of patients with a fracture to any part of their four extremities, clavicle, hand or foot, who underwent surgical plate osteosynthesis from January 2005 to January 2015, and who sustained a subsequent implant breakage. Kaplan-Meier univariate and multivariate Cox regressions were performed to identify independent associations of potential risk factors for implant breakage in this cohort. We identified 168 patients who underwent plate osteosynthesis surgery and had subsequent internal fixator breakage. The mean patient age was 40.63 ± 16.71 years (range, 3 to 78 years), with 72.0% (121) males and 28.0% (47) females. The average time between surgery and implant breakage was 12.85 ± 12.42 months (range, 1 to 60 months). In the final regression model, we show that inserting screws close to the fracture line is an independent predictive risk factor for implant breakage (HR, 2.165, 95%CI, 1.227 to 3.822; P = 0.008). We found that inserting screws close to the fracture line is related to an increased risk of internal fixator breakage in patients treated with plate osteosynthesis after fracture. Plates with additional holes likely lead to an increased risk of implant breakage, presumably because surgeons cannot resist inserting extra screws into the holes adjacent to the fracture line, which reduces the stiffness of the plate. We have addressed this problem by designing a plate without holes adjacent to the fracture line.

    Ankle fractures are common and represent a significant burden to society. We aim to report the rate of union as determined by clinical and radiographic data, and to identify factors that predict time to union. A cohort of 112 consecutive patients with isolated, closed, operative malleolar ankle fractures treated with open reduction and internal fixation was retrospectively reviewed for time to clinical union. Clinical union was defined based on radiographic and clinical parameters, and delayed union was defined by time to union >12 weeks. Injury characteristics, patient factors and treatment variables were recorded, and statistical techniques employed included the Chi-square test, the Student's T-test, and multivariate linear regression modeling. Forty-two (37.5%) of patients who achieved union did so in less than 12 weeks, and 69 (61.6%) of these patients demonstrated delayed union at a mean of 16.7 weeks (range, 12.1-26.7 weeks), and the remaining patient required revision surgery. Factors associated with higher rates of delayed union or increased time to union included tobacco use, bimalleolar fixation, and high energy mechanism (all punion were BMI, dislocation of the tibiotalar joint, external fixation for initial stabilization and delay of definitive management (all punion following open reduction and internal fixation of closed ankle fractures. These findings should assist with patient counseling, and help guide the provider when considering adjunctive therapies that promote bone healing. Prognostic, Level IV: Case series.

    Distal humerus intercondylar fractures are intra-articular and comminuted fractures involving soft tissue injury. As distal humerus is triangle-shaped, parallel plating coupled with articular fixation would be suitable for bicolumn restoration in treatment of distal humerus intercondylar fracture. This study included 38 patients (15 males and 23 females) who underwent olecranon osteotomy, open reduction and internal fixation with the triangle-shaped cannulated screw and parallel locking plates (triangular fixation technique). Functional results were assessed with the visual analog scale (VAS) scores, Mayo elbow performance (MEP) scores and Disabilities of the Arm, Shoulder and Hand (DASH) questionnaires. Anteroposterior and lateral elbow radiographs were assessed for reduction, alignment, fracture union, posttraumatic arthrosis, and heterotopic ossification, and computed tomography (CT) scans were used to obtain more accurate measurements of articular discrepancy. All fractures healed primarily with no loss of reduction. The mean VAS, MEP, and DASH scores of the affected elbow were not significantly different from those of the unaffected elbow (p = 0.140, p = 0.090, and p = 0.262, respectively). The mean degree of flexion was significantly lower in the affected elbow than in the unaffected elbow, but was still considered as functional (p = 0.001, > 100° in 33 of 38 patients). Two cases of articular step-offs (> 2 mm) were seen on follow-up CT scans, but not significantly higher in the affected elbow than in the unaffected elbow (p = 0.657). Binary logistic regression analysis revealed that only Association for Osteosynthesis (AO) type C3 fractures correlated with good/excellent functional outcome (p = 0.012). Complications occurred in 12 of the 38 patients, and the overall reoperation rate for complications was 10.5% (4 of 38 patients). Triangular fixation technique for bicolumn restoration was an effective and reliable method in treatment of distal humerus

    Acetabular fractures are mainly caused by high energy trauma. Surgical fixation of these fractures requires extensive surgical exposure which increases the length of operation and blood loss as well. This may increase the risk of surgical site infection. Our aim is to evaluate the prevalence of surgical site infections and the risk factors associated with it so as to minimize its chances. A total of 261 patients who underwent acetabular fracture surgery were retrospectively reviewed. Patients were divided into 2 groups, with or without surgical site infection. Factors examined include patients' gender, age, body mass index (BMI), time between injury and surgery, operative time, estimated blood loss, number of packed red blood cell transfused, length of total intensive care unit (ICU) stay, fracture type, surgical approach, smoking status, patients' comorbids and associated injuries. Fourteen patients (5.4%) developed surgical site infection. Out of 14 infections, 4 were superficial and 10 were deep. The factors that were found to be associated with surgical site infection following acetabular fracture fixation were prolonged operation time, increased BMI, prolonged ICU stay, larger amount of packed red blood cell transfused and associated genitourinary and abdominal trauma. In our study, we conclude that measures should be undertaken to attenuate the chances of surgical site infection in this major surgery by considering the risk factors significantly associated with it.

    This prospective, randomized study compared the effectiveness of the cable pin system (CPS) versus tension band wiring (TBW) for olecranon fracture fixation. Patients with acute transverse or slight oblique olecranon fractures were randomly divided into two groups: one fixed by CPS and the other by TBW. Clinical outcome data were collected and analysed following a mean duration of 21 months. The mean ± SD fracture healing time was significantly shorter in the CPS group (n = 30; 9.73 ± 2.02 weeks) compared with the TBW group (n = 32; 11.13 ± 2.21 weeks). One patient in the CPS group and seven patients in the TBW group experienced postoperative complications; this difference was statistically significant. The mean ± SD Mayo Elbow Performance Score in the CPS group was significantly higher (88.67 ± 6.42) than that in the TBW group (80.78 ± 11.99). Logistic regression analysis showed an association between fixation method and fracture healing time, complications and elbow function. Internal fixation by CPS is an effective method for olecranon fracture and is associated with a shorter healing time, fewer complications and better function than TBW.

    Full Text Available Abstract Background Volar locking plates provide significant structural stability to the distal radius. Failure of a volar locked plating is a rarely reported complication in the literature. Case Presentation A 40 year-old, obese female patient who presented with a displaced extraarticular distal radius fracture, underwent open reduction and internal fixation of the fracture using a volar locking plate. Radiographs taken at 10 weeks postoperatively showed failure of fixation with breakage of the four distal locking screws. A hardware removal was performed at 6 months, and the patient was then lost to follow-up. She presented again at 18 months after the first surgery, with significant pain, and radiographic signs of a radial collapse and a fracture-nonunion. A total wrist fusion was performed as the method of choice at that point in time. Conclusion Volar locked plating represents the new "gold standard" of distal radius fracture fixation. However, despite the stability provided by locking plates, hardware failure may occur and lead to a cascade of complications which will ultimately require a wrist fusion, as outlined in this case report. Additional structural support by bone grafting may be needed in selected cases of volar locked plating, particularly in patients with a high risk of developing a fracture-nonunion.

    Comminuted fibular fractures can occur with pilon fractures as a result of valgus stress. Transverse fibular fractures can occur with varus deformation. No definitive guide for determining the proper location of tibial fixation exists. The purpose of this study was to identify optimal plate location for fixation of pilon fractures based on the orientation of the fibular fracture. One hundred two patients with 103 pilon fractures were identified who were definitively treated at our institution from 2004 to 2013. Pilon fractures were classified using the AO/OTA classification and included 43-A through 43-C fractures. Inclusion criteria were age of at least 18 years, associated fibular fracture, and definitive tibial plating. Patients were grouped based on the fibular component fracture type (comminuted vs transverse), and the location of plate fixation (medial vs lateral) was noted. Radiographic outcomes were assessed for mechanical failures. Forty fractures were a result of varus force as evidenced by transverse fracture of the fibula and 63 were due to valgus force with a comminuted fibula. For the transverse fibula group, 14.3% mechanical complications were noted for medially placed plate vs 80% for lateral plating ( P = .006). For the comminuted fibular group, 36.4% of medially placed plates demonstrated mechanical complications vs 16.7% for laterally based plates ( P = .156). Time to weight bearing as tolerated was also noted to be significant between groups plated medially and laterally for the comminuted group ( P = .013). Correctly assessing the fibular component for pilon fractures provides valuable information regarding deforming forces. To limit mechanical complications, tibial plates should be applied in such a way as to resist the original deforming forces. Level of Evidence Level III, comparative study.

  9. Intramedullary nail fixation of non-traditional fractures: Clavicle, forearm, fibula.

    2017-06-01

    Locked intramedullary fixation is a well-established technique for managing long-bone fractures. While intramedullary nail fixation of diaphyseal fractures in the femur, tibia, and humerus is well established, the same is not true for other fractures. Surgical fixations of clavicle, forearm and ankle are traditionally treated with plate and screw fixation. In some cases, fixation with an intramedullary device is possible, and may be advantageous. However, there is however a concern regarding a lack of rotational stability and fracture shortening. While new generation of locked intramedullary devices for fractures of clavicle, forearm and fibula are recently available, the outcomes are not as reliable as fixation with plates and screws. Further research in this area is warranted with high quality comparative studies, to investigate the outcomes and indication of these fractures treated with intramedullary nail devices compared to intramedullary nail fixation.

    The goal of this study was to report the results of selective open reduction and internal fixation of fractures of the posterior malleolus with a posterolateral approach and to compare the results of the 2 techniques. We prospectively evaluated 40 patients who underwent posterior malleolar fracture fixation between 2008 and 2012. The patients were treated with a posterolateral approach. We assigned alternating patients to receive plate fixation and the next screw fixation, consecutively, based on the order in which they presented to our institution. Fixation of the posterior malleolus was made with lag screws in 20 patients and a buttress plate in 20 patients. We used American Orthopaedic Foot and Ankle Society (AOFAS) scores, range of motion (ROM) of the ankle, and radiographic evaluations as the main outcome measurements. The mean follow-up was 38.2 (range, 24-51) months. Full union without any loss of reduction was obtained in 38 of the 40 patients. We detected a union with a step-off of 3 mm in 1 patient in the screw group and a step-off of 2 mm in 1 patient in the plate group. At the final follow-up, the mean AOFAS score of the patients regardless of fixation type was 94.1 (range, 85-100). The statistical results showed no significant difference between the patients regardless of the fixation type of the posterior malleolus in terms of AOFAS scores and ROM of the ankle (P > .05). Good (AOFAS score of 94/100) and equivalent (within 3 points) results were obtained using the 2 techniques (screws or plate) for fixation after open reduction of posterior malleolar fragments.

    To evaluate the results obtained from treatment of humeral shaft fractures and their complications using the Osteoline(®) uniplanar external fixator. The radiographic and functional results from 78 patients with humeral shaft fractures treated using the uniplanar external fixation technique were retrospectively assessed. The patients' ages ranged from 23 to 71 years, with a mean of 47 years. Male patients predominated (79%). Out of the 78 patients, 45 presented open fractures, 14 presented pseudarthrosis and six presented synthesis failure. There were no losses during the follow-up and all the patients were discharged after fracture consolidation and functional recovery. The results were evaluated based on the studies by Catagni, as good, fair or poor. Fracture consolidation was observed in 98% of the cases treated with uniplanar external fixation. Only one pseudarthrosis case required conversion to rigid internal fixation and autologous bone grafting. At the end of the treatment, all the patients were discharged with consolidated fractures, without pain, and good limb function. The external fixation described in this paper was shown to be an efficient and safe method for treating humeral shaft fractures and their complications. It preserved the local biological status and enabled passive and active movement immediately after surgery.

    To critically evaluate whether open fracture fixation is a significant risk factor for latent osteosarcoma development. Case-control study. Dogs undergoing open fracture repair and dogs diagnosed with osteosarcoma. Records were retrieved from the Veterinary Medical Database VMDB (1970-2000) for dogs undergoing surgical repair of a fracture and dogs diagnosed with osteosarcoma. Dogs with open reduction of joint luxation, dogs diagnosed with bacterial cystitis, and dogs diagnosed with urinary bladder transitional cell carcinoma (UBTCC) were queried as comparison populations. Relative risk for osteosarcoma development was determined. From a population of 19,041 fractures treated surgically, 15 of those dogs subsequently appeared in the VMDB with osteosarcoma affecting the same bone. The relative risk of a fracture repair and associated orthopedic implants and osteosarcoma occurrence was equivalent to the relative risk of open joint reduction and osteosarcoma occurrence (95% confidence interval; 0.998-1.00). The relative risk of having bacterial cystitis and appearing again in the VMDB with UBTCC was higher than the risk of open fracture repair and a subsequent diagnosis of osteosarcoma (P risk of osteosarcoma after fracture repair may not be warranted and merits further investigation. © Copyright 2015 by The American College of Veterinary Surgeons.

  15. Management of subtrochanteric femur fractures with internal fixation and recombinant human bone morphogenetic protein-7 in a patient with osteopetrosis: a case report

    Science.gov (United States)

    2010-01-01

    Introduction Osteopetrosis is a group of conditions characterized by defects in the osteoclastic function of the bone resulting in defective bone resorption. Clinically, the condition is characterized by a dense, sclerotic, deformed bone which, despite an increased density observable by radiography, often results in an increased propensity to fracture and delayed union. Case Presentation We report the case of a 27-year-old Asian man presenting with bilateral subtrochanteric femur fractures. He had a displaced right subtrochanteric femur fracture after a low-energy fall, which was treated surgically. The second fracture that our patient endured was diagnosed as a stress fracture ten weeks later when he complained of pain in the contralateral left thigh. By that time, the right-sided fracture exhibited no radiographic evidence of healing, and when the left-sided stress fracture was being treated surgically, bone grafting with recombinant human bone morphogenetic protein-7 was also performed on the right side. Conclusion While there are no data supporting the use of bone morphogenic proteins in the management of delayed healing in patients with osteopetrosis, no other reliable osteoinductive grafting options are available to treat this condition. Both fractures in our patient healed, but based on the serial radiographic assessment it is uncertain to what degree the recombinant human bone morphogenetic protein-7 may have contributed to the successful outcome. It may have also contributed to the formation of heterotopic bone around the fracture site. Further investigation of the effectiveness and indications of bone morphogenic protein use for the management of delayed fracture healing in patients with osteopetrosis is warranted. PMID:20482845

    Three horses that were presented with supraglenoid tubercle fractures were treated with open reduction and internal fixation using distal femoral locking plates (DFLP). Placing the DFLP caudal to the scapular spine in order to preserve the suprascapular nerve led to a stable fixation, however, it resulted in infraspinatus muscle atrophy and mild scapulohumeral joint instability (case 1). Placing the DFLP cranial to the scapular spine and under the suprascapular nerve resulted in a stable fixation, however, it resulted in severe atrophy of the supraspinatus and infraspinatus muscles and scapulohumeral joint instability (case 2). Placing the DFLP cranial to the scapular spine and slightly overbending it at the suprascapular nerve passage site resulted in the best outcome (case 3). Only a mild degree of supraspinatus and infraspinatus muscle atrophy was apparent, which resolved quickly and with no effect on scapulohumeral joint stability. In all cases, fixation of supraglenoid tubercle fractures using DFLP in slightly different techniques led to stable fixations with good long-term outcome. One case suffered from a mild incisional infection and plates were removed in two horses. Placement of the DFLP cranial to the scapular spine and slightly overbending it at the suprascapular nerve passage prevented major nerve damage. Further cases investigating the degree of muscle atrophy following the use of the DFLP placed in the above-described technique are justified to improve patient outcome.

    Full Text Available Background: We report the functional impact and natural history of cutaneous hypoesthesia after plate internal fixation for mid shaft clavicle fractures with a horizontal skin incision from year 2009 to 2011. Materials and Methods: 38 patients had complete followup data with an average followup period of 23.2 months (range 8-43 months. The impact of supraclavicular nerve injury was studied by assessment of the incidence, functional impact and natural history of numbness with detailed review of the case records and phone questionnaires. Results: The incidence of postoperative numbness was 55.3% (n = 21. Most patients reported the numbness to be at its worst within the first operative month. At the time of worst numbness, 28.6% (n = 6/21 of patients reported the numbness to be severe while 42.9% (n = 9/21 reported moderate numbness and 28.6% (n = 6/21 reported mild numbness. Fifteen of these patients described increased awareness of numbness during contact with straps or clothes. Two patients were significantly bothered by this numbness; 4 patients stated that it was a moderate bother while 7 patients considered it a mild bother. A total of 8 patients reported that they were not bothered at all by the numbness. An overwhelming majority of affected patients (90.5%, n = 19/21 reported an improvement in the severity of numbness felt over time. At the last followup, the incidence of numbness declined from 55.3% to 36.8% with 7 patients reporting complete resolution of numbness. The numbness however was found to persist in 66.7% of patients. Only 1 patient reported continued severe numbness. The awareness of numbness with straps and clothing was severe in 5 patients. None of the patients were significantly bothered by this numbness. Conclusions: Cutaneous sensory loss is a common occurrence following plate fixation of the clavicle and might have been under reported in the literature. The numbness improves in the vast majority, but commonly persists to

    Full Text Available Renal transplantation, performed per million population, ranges from 30 to 60 in developed countries. The transplanted kidney is generally placed in iliac fossa; therefore the treatment procedure of the pelvic trauma in these patients should be selected carefully. The gold standard technique for the treatment of displaced acetabulum fractures is open reduction and internal fixation. Our patient had received a living-related-donor renal transplant due to chronic renal failure. In the second year of transplantation, she had been injured in a motor-vehicle accident, and radiographs showed a right acetabular anterior column fracture and left pubic rami fractures. The patient was treated with percutaneous fixation techniques and at one year of postoperative period there was no evidence of degenerative signs and the clinical outcome was good. Beside having the advantage of avoiding dissection through the iliac fossa by the standard ilioinguinal approach, percutaneous techniques, with shorter surgical time, decreasing soft tissue disruption, and the potential for early discharge from hospital might be ideal for a renal transplant recipient carrying a higher risk of infection. Percutaneous fixation of selected acetabular fractures in a renal transplant recipient would presumably have the potential to decrease the morbidity associated with traditional open surgical procedures.

    To evaluate the technique and effectiveness of dual plating fixation for distal fibular comminuted fractures. Between November 2010 and November 2011, 16 patients with distal fibular comminuted fractures were treated, including 10 males and 6 females with an average age of 49.8 years (range, 35-65 years). All the patients had closed injury, which was caused by sprain in 9 cases, by traffic accident in 5 cases, and by falling in 2 cases. The average interval from injury to admission was 8 hours (range, 1-48 hours). Routine X-ray and CT scan were taken for confirmation of classification and involvement. According to Weber classification system, 11 cases were rated as type A, and 5 as type B; 5 cases had bimalleolar fractures with medial malleolar fracture, and 2 cases had trimalleolar fractures with posterior and medial malleolar fracture. Open reduction and dual plating fixation were performed after swelling was subsided. The X-ray films were taken during follow-up. The effectiveness was evaluated with visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot and ankle score system at last follow-up. The range of motion (ROM) of the ankle and complications were also been recorded. Delayed healing of incision occurred in 1 patient with diabetes, who was cured after changing dressing; primary healing was obtained in the other patients. Twelve patients were followed up 18 months on average (range, 12-24 months). Radiographic examination demonstrated the mean time of bone healing was 12 weeks (range, 10-14 weeks). No complication of implant failure, malunion, nonunion, or post-traumatic arthritis occurred during follow-up. The AOFAS hindfoot and ankle score was 79.6 +/- 6.5, and the VAS score was 1.3 +/- 1.5. The ROM of the ankle was (70.0 +/- 8.0) degrees of flexion and (84.0 +/- 5.1) degrees of extension. Dual plating fixation for distal fibular comminuted fractures can obtain a rigid stabilization with a low complication incidence

    Ankle fractures involving syndesmosis disruption cause severely unstable joint conditions. Traditional invasive operations put certain patient groups at an increased risk of infection. There is limited literature discussing the outcomes of minimally invasive fixation of severe ankle fractures including syndesmotic injury, as clinicians may be tempted to treat these difficult cases with open reduction internal fixation (ORIF). A retrospective case-control study was conducted on patients treated at a level one trauma center. Patients were divided into 2 groups based on presence of diabetes and/or obesity (body mass index ≥30.0 kg/m 2 ). Those with either comorbidity were defined as high infection risk patients and placed in a comorbidity group. Patients were further divided into subgroups based on the operation's invasiveness; either traditional ORIF or percutaneous cannulated screw fixation. Comorbid patients (N = 67) were more likely to sustain Weber C fractures compared to noncomorbid patients (N = 43) (59.70% to 37.21%, P = .019). Additionally, patients receiving minimally invasive fixation procedures experienced fewer infections than those receiving ORIF (0 vs 11 incidences, P = .01), without effect on union rates, fracture reduction, pain, need for revision surgery, or time to full weightbearing. Diabetic and obese patients are at an increased risk of experiencing severe ankle fractures. The use of minimally invasive fixation methods can reduce the risk of postoperative infection without sacrificing other surgical outcomes, even with fractures involving syndesmotic injury.

    Early intervention with minimally invasive surgery has significantly less morbidity and a reliable early return to active sports and is therefore the best option in high-performance athletes. Materials and Methods: Nine athletes with ten stress fractures of the navicular treated at our institution between April 1991 and October 2000. The mean age of the patients was 22.8 years (range 18-50 years. All patients were treated by minimally invasive screw fixation and early weight bearing mobilization without a cast. The average followup was 7 years (range 2-11 years. Results: Seven of the nine patients returned to their pre-fracture level of sporting activity at an average of 5 months (range 3-9 months. One patient returned to full sporting activity following a delay of 2 years due to an associated tibial stress fracture and one patient had an unsatisfactory result. Long term review at an average of 7 years showed that six of these eight patients who returned to sports remained symptom free with two patients experiencing minimal intermittent discomfort after prolonged activity. Conclusions: We recommend percutaneous screw fixation as a reliable, low morbidity procedure allowing early return to full sporting activity without long term complications or recurrences.

    2015-01-01

    Full Text Available This study aims to evaluate the biomechanical mechanism of fixation systems in the most frequent T-shaped acetabular fracture using finite element method. The treatment of acetabular fractures was based on extensive clinical experience. Three commonly accepted rigid fixation methods (double column reconstruction plates (P × 2, anterior column plate combined with posterior column screws (P + PS, and anterior column plate combined with quadrilateral area screws (P + QS were chosen for evaluation. On the basis of the finite element model, the biomechanics of these fixation systems were assessed through effective stiffness levels, stress distributions, force transfers, and displacements along the fracture lines. All three fixation systems can be used to obtain effective functional outcomes. The third fixation system (P + QS was the optimal method for T-shaped acetabular fracture. This fixation system may reduce many of the risks and limitations associated with other fixation systems.

    To compare the clinical effects of external fixator versus DVR system for the treatment of AO type C distal radius fractures. The clinical data of 52 patients with type C distal radial fractures treated with external fixator or DVR system respectively from January 2009 to December 2013 were analyzed retrospectively. In DVR system group, 31 patients were treated by open reduction and internal fixation with DVR system, involved 11 males and 20 females, with an average age of(47.3±10.9) years ranging from 24 to 65 years;according to AO/ASIF classification, 12 cases were type C1, 15 cases were type C2, 4 cases were type C3. In external fixator group, 21 patients were treated by closed reduction and cross wrist external fixation, involved 8 males and 13 females, with an average age of (48.1±12.1) years ranging from 26 to 69 years; according to AO/ASIF classification, 7 cases were type C1, 11 cases were type C2, 3 cases were type C3. The postoperative images, wrist joint functions and Gartland-Wetley scores were evaluated and compared. Thirty-one patients in DVR system group were followed up for 20.4 months(ranged from 13 to 36 months) and in external fixator group 21 patients were followed up for 17.1 months (ranged from 11 to 33 months) respectively. X-rays showed all fractures healed. The palm dip and radial inclination in the DVR system group were significantly better than in the external fixator group( P 0.05). There was 1 case of wrist stiffness in the DVR system group; 2 cases of pin tract infection, 1 case of fixator loosening and 2 cases of wrist stiffness in the external fixator group. Clinical outcomes of DVR system fixation for type C distal radial fractures are better than that of external fixator fixation. However, DVR system fixation costs more and requires a secondary surgery to remove the internal fixation. The choices of surgical method depend on the clinical conditions of the patients.

    For the calcaneal avulsion fracture, the current method is more commonly used screws or Kirschner wire to fix fracture fragment. This article intended to explore the feasibility and clinical efficacy for the treatment of avulsion fractures with TwinFix suture anchors. From July 2007 to November 2010, 21 patients were reviewed, including 15 males and 6 females, ranging in age from 49 to 65 years,with a mean of 58.7 years. Twelve patients had nodules in the right heel and 9 patients had nodules in the left heel. All the patients had closed fractures. The typical preoperative symptoms of the patients included pain in the upper heel and weak in heel lift. Body examination results: palpable sense of bone rubbing in the back of the heel, and swelling in the heel. Surgery treatment with TwinFix suture anchors performed as follows : to fix TwinFix suture anchors into the calcaneal body, then to drill the fracture block, to make the double strand suture through the fracture holes, to knot the suture eachother to fix the block, and to use stitch to fix the remaining suture in the Achilles tendon in order to improve the block fixation. The criteria of the AOFAS Foot and Ankle Surgery by the United States Association of ankle-rear foot functional recovery was used to evaluate the Achilles tendon. Total average score was (95.5 +/- 3.12) points, including pain items of(38.5 +/- 2.18) points,the average score of functional items of (49.5 +/- 3.09) points,and power lines of 10 points in all patients. Twenty-one patients got an excellent result, 16 good and 5 poor. The methods of treatment for the calcaneal avulsion fractures with TwinFix suture anchors is a simple operation, and have excellent clinical effect, which is worthy of promotion.

    Close contact casting (CCC) may offer an alternative to open reduction and internal fixation (ORIF) surgery for unstable ankle fractures in older adults. We aimed to (1) determine if CCC for unstable ankle fractures in adults aged over 60 years resulted in equivalent clinical outcome compared with ORIF, (2) estimate cost-effectiveness to the NHS and society and (3) explore participant experiences. A pragmatic, multicentre, equivalence randomised controlled trial incorporating health economic evaluation and qualitative study. Trauma and orthopaedic departments of 24 NHS hospitals. Adults aged over 60 years with unstable ankle fracture. Those with serious limb or concomitant disease or substantial cognitive impairment were excluded. CCC was conducted under anaesthetic in theatre by surgeons who attended training. ORIF was as per local practice. Participants were randomised in 1 : 1 allocation via remote telephone randomisation. Sequence generation was by random block size, with stratification by centre and fracture pattern. Follow-up was conducted at 6 weeks and, by blinded outcome assessors, at 6 months after randomisation. The primary outcome was the Olerud-Molander Ankle Score (OMAS), a patient-reported assessment of ankle function, at 6 months. Secondary outcomes were quality of life (as measured by the European Quality of Life 5-Dimensions, Short Form questionnaire-12 items), pain, ankle range of motion and mobility (as measured by the timed up and go test), patient satisfaction and radiological measures. In accordance with equivalence trial US Food and Drug Administration guidance, primary analysis was per protocol. We recruited 620 participants, 95 from the pilot and 525 from the multicentre phase, between June 2010 and November 2013. The majority of participants, 579 out of 620 (93%), received the allocated treatment; 52 out of 275 (19%) who received CCC later converted to ORIF because of loss of fracture reduction. CCC resulted in equivalent ankle

    We present a novel technique of intramedullary fixation of the fibula using a humeral guide wire as an adjunct to tibial fixation, in the setting of tibial shaft fracture. Not only does this technique aid in determining length, alignment, and rotation of the tibial fracture, but it may also help the support of the lower extremity as whole by stabilizing the lateral column. In addition, this technique can be used to help maintain reduction of the fibula when there is concern for the soft tissues of the lower extremity secondary to swelling or injury. Our clinical case series demonstrates this safe, effective, and cost-sensitive technique to be used in the treatment of select concurrent fractures of the tibia and fibula.

    This study aims to investigate whether surgical treatment of pubic rami fractures increases the stability of the posterior pelvis. A finite element pelvic model with improved geometric and material characteristics was analyzed. By imitating a standing position, a type I Denis sacrum fracture and a unilateral pubis fracture, we measured the differences in tension and displacement. The posterior injury was treated with a direct plate synthesis or transsacral plate synthesis, while the pubis fracture was left without fixation or fixed with either a retrograde pubic screw or plate synthesis. The operative fixation of pubic rami fractures decreased the movement in the fracture gap not only at the site of the pubis fracture, but also at the site of the fixed sacrum fracture. The plate synthesis provided greater stability of the anterior fracture than the retrograde screw. The tensions in the implants were below the allowed values. We concluded that surgically fixation of pubic fracture increases the stability of the operated posterior pelvis.

    To explore the clinical outcomes of open reduction and internal fixation with calcaneal locking plates in treating Sanders type II and III calcaneal fractures. From January 2010 and October 2012, 38 calcaneal fractures with Sanders type II or III were treated with open reduction and internal fixation with calcaneal locking plate. According to the Sanders classification, 15 fractures were classified as type II, 23 fractures as type III. The patients were divided into two groups (group A and B) according to the different fixed methods. Sustentaculum tali was fixed with one screw in group A, including 13 males and 5 females, with a mean age of (38.56±8.03) years old (ranged, 25 to 55). And sustentaculum tali was not fixed in group B, including 16 males and 4 females, with a mean age of (42.35±8.29) years old (ranged, 29 to 53). Clinical effects were evaluated according to the changes of Böhler's angle and the Maryland Foot Score and VAS score. All patients were followed up from 12 to 20 months with a mean of 14 months. Böhler's angles and subtalar joints obtained satisfactory reconstruction in all patients. One year after operation, the mean Maryland Foot Score was 88.61±7.59 in group A; and was 82.40±9.24 in group B; Maryland Foot Score of group A was higher and foot functional rehabilitation was better than group B. The mean VAS score was 13.39±11.47 in group A; and was 22.50±13.10 in group B; VAS score of group A was lower and foot pain was less than group B. Sustentaculum tall screw fixation has advantages of strong fixed strength, high stability, less postoperative pain, rapid functional recovery in treating Sanders type II and III calcaneal fractures.

    The aim of this study was to retrospectively compare a series of patients surgically treated with ORIF or early resection arthroplasty due to isolated comminuted radial head fractures. Between the years 2009 and 2013, 34 patients with isolated comminuted fractures of the radial head (Mason Type 3) had been operated (ORIF in 19 patients, resection arthroplasty in 15 patients). The mean age of the patients in the ORIF group was 38.5 years and 54 years in the resection group. The carrying angle (CA) and ulnar variance were measured bilaterally, and radiographs were reviewed for degenerative elbow arthritis. The Mayo elbow performance score, Turkish version of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH-T) and visual analog scale (VAS) were used to evaluate the clinical results. The mean follow-up period in the ORIF group was 40.2 months and 44.4 months in the resection group. In the ORIF group, 11 patients were clinically rated excellent, six good, and two fair. In the resection group, seven patients had excellent, five had good, and two had fair scores. We did not find a statistically significant difference between the ORIF and resection groups regarding the clinical and radiological outcomes. With these short-term results, resection arthroplasty may be considered an effective method in the treatment of isolated comminuted radial head fractures, as it is less technically demanding and it also allows for early postoperative motion. However, the patients should be evaluated in detail, regarding ligamentous injuries prior to resection arthroplasty. Level III, Therapeutic study.

    Delayed or non-union of a sacral fracture is a serious clinical condition that may include chronic pain, sitting discomfort, gait disturbances, neurological problems, and inability to work. It is also a difficult reconstruction problem. Late correction of the deformity is technically more demanding than the primary treatment of acute pelvic injuries. Open reduction, internal fixation (ORIF), excision of scar tissue, and bone grafting often in a multi-step approach are considered to be the treatment of choice in delayed unions of the pelvic ring. This procedure implies the risk of neurological and vascular injuries, infection, repeated failure of union, incomplete correction of the deformity, and incomplete pain relief as the most important complications. We report a new approach for minimally invasive treatment of a delayed union of the sacrum without vertical displacement. A patient who suffered a Malgaigne fracture (Tile C1.3) was initially treated with closed reduction and percutaneous screw fixation (CRPF) of the posterior pelvic ring under CT navigation and plating of the anterior pelvic ring. Three months after surgery he presented with increasing hip pain caused by a delayed union of the sacral fracture. The lesion was successfully treated percutaneously in a single step procedure using CT navigation for drilling of the delayed union, autologous bone grafting, and screw fixation

    An intracapsular femoral neck fracture in a young patient is a rare and difficult injury to manage. The occurrence of complications following fixation is multifactorial. Initial displacement and timing and accuracy of reduction are the key factors affecting outcome. The severities of the trauma to the hip and the impact of the intracapsular hematoma also play a role, the importance of which remains poorly understood. The purpose of this study was to evaluate the high incidence of femoral neck fractures treated in our institution over a 7-month period, to record the long-term outcome of these patients, all of whom were treated with contemporary methods of internal fixation, and to highlight the reasons for this injury being termed an "orthopedic emergency" and its differences from the same injury in the elderly population. We performed a retrospective analysis of 12 cases of intracapsular femur neck fracture in patients younger than 50 years treated over 7 months in a regional trauma center. All patients underwent satisfactory reduction and fixation. Nine of the 12 patients had a good outcome at a mean follow-up of 29 months. One patient developed a nonunion of the femoral head requiring total hip arthroplasty, one developed avascular necrosis of the femoral head, and one developed partial avascular necrosis. This compares favorably with other studies.

    Full Text Available Background: Management of nonunion with bony defect and infection in long bones is a challenging problem for orthopedic surgeons. Objectives: Evaluation of Ilizarov circular fixation method of treatment for the management of nonunited and infected fractures of tibia. Materials and Methods: This prospective study was conducted in a tertiary care hospital of eastern region of India on 30 subjects in a time span of 3 years after taking clearance of the Institutional Ethical Committee and informed consent of the patients. Results: All the patients had infected nonunion before undergoing Ilizarov procedure. Following initial injury, 22 patients were treated with external fixation and 8 cases were treated with internal fixation. At the time of presentation, 18 patients had infected gap nonunion, 5 patients had infected hypertrophic and 2 patients had atrophic nonunion. The Ilizarov fixator was kept for an average period of 303.7 days. Based on Association for the Study and Application of Methods of Ilizarov scoring system, bony and functional results were assessed. The bony result was excellent in 16 patients, good in eight, fair in four and poor in two. The functional result was excellent in 10 patients, good in 16, fair in two, poor in two. Conclusion: Ilizarov ring fixator still remains an excellent treatment modality for tibial nonunion with a defect, regarding bone union, deformity correction, infection eradication, limb-length achievement, and limb function.

  14. A new adhesive technique for internal fixation in midfacial surgery

    Directory of Open Access Journals (Sweden)

    Riediger Dieter

    2008-05-01

    Full Text Available Abstract Background The current surgical therapy of midfacial fractures involves internal fixation in which bone fragments are fixed in their anatomical positions with osteosynthesis plates and corresponding screws until bone healing is complete. This often causes new fractures to fragile bones while drilling pilot holes or trying to insert screws. The adhesive fixation of osteosynthesis plates using PMMA bone cement could offer a viable alternative for fixing the plates without screws. In order to achieve the adhesive bonding of bone cement to cortical bone in the viscerocranium, an amphiphilic bone bonding agent was created, analogous to the dentin bonding agents currently on the market. Methods The adhesive bonding strengths were measured using tension tests. For this, metal plates with 2.0 mm diameter screw holes were cemented with PMMA bone cement to cortical bovine bone samples from the femur diaphysis. The bone was conditioned with an amphiphilic bone bonding agent prior to cementing. The samples were stored for 1 to 42 days at 37 degrees C, either moist or completely submerged in an isotonic NaCl-solution, and then subjected to the tension tests. Results Without the bone bonding agent, the bonding strength was close to zero (0.2 MPa. Primary stability with bone bonding agent is considered to be at ca. 8 MPa. Moist storage over 42 days resulted in decreased adhesion forces of ca. 6 MPa. Wet storage resulted in relatively constant bonding strengths of ca. 8 MPa. Conclusion A new amphiphilic bone bonding agent was developed, which builds an optimizied interlayer between the hydrophilic bone surface and the hydrophobic PMMA bone cement and thus leads to adhesive bonding between them. Our in vitro investigations demonstrated the adhesive bonding of PMMA bone cement to cortical bone, which was also stable against hydrolysis. The newly developed adhesive fixing technique could be applied clinically when the fixation of osteosynthesis plates

    Calcaneal avulsion fractures are not uncommon, and they are probably more likely in patients with osteoporosis. Closed manipulation for this type of fracture often fails to achieve acceptable reduction, and open reduction and internal fixation are usually required. However, open reduction and internal fixation with either a lag screw or Steinmann pins do not provide satisfactory fixation in patients with diabetes and elderly patients because of the presence of porotic bone. Levi described a tension band fixation system used to treat a calcaneal avulsion fracture using a simple technique performed with a transverse Kirschner wire through the os calcaneus, securing a figure-of-8 metal tension band wiring to the fragment. We report the successful treatment of 3 patients with calcaneal avulsion fractures using a modified tension band wiring technique, resulting in satisfactory recovery. Re-displacement of the fragment during the initial follow-up period was not reported, and bony union was achieved in all patients. We believe this technique is a useful surgical option for the treatment of calcaneal avulsion fractures. Copyright © 2012 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

    Ten pigeons (Columba livia domestic form) with humeral diaphyseal fracture were treated with external and internal fixation techniques (Boston technique and intamedullary pin). Longitudinal space was intentionally left between fracture surfaces during osteosynthesis. This space was filled with bovine lyophilized collagen, set around an intramedullary pin, in five samples. Ossification process was checked by radiography every seven days. Results show the utility of this technique in pneumatic bird bones. In fact, shortening control and callus formation facility were observed [it

    Abstract Background Non-unions are severe complications in orthopaedic trauma care and occur in 10% of all fractures. The golden standard for the treatment of ununited fractures includes open reduction and internal fixation (ORIF) as well as augmentation with autologous-bone-grafting. However, there is morbidity associated with the bone-graft donor site and some patients offer limited quantity or quality of autologous-bone graft material.

    Intramedullary screw fixation of fifth metatarsal Jones fractures often produces satisfactory results, however, nonunion and refracture rates are not negligible. The low-profile "hook" plate is an alternative fixation method that has been promoted to offer improved rotational control at the fracture site, but this remains to be proven. The purpose of this study was to document biomechanical performance differences between this type of plate and a contemporary solid, dual-pitch intramedullary screw in a cadaveric Jones fracture model. Simulated Jones fractures were created in 8 matched pairs of fresh-frozen cadaveric fifth metatarsals. One bone from each pair was stabilized using an intramedullary TriMed Jones Screw and the other using a TriMed Jones Fracture Plate (TriMed, Inc, Santa Clarita, CA). Controlled bending and torsional loads were applied. Bending stiffness and fracture site angulation, as well as torsional stiffness, peak torque, and fracture site rotation were quantified and compared. Intramedullary screw fixation demonstrated greater bending stiffness and less fracture site angulation than plate fixation during plantar-to-dorsal and lateral-to-medial bending. Torsional stiffness of screw-fixed metatarsals exceeded that of plate-fixed bones at initial loading; however, as rotation progressed, the plate resisted torque better than the screw. No difference in peak torque was demonstrable between fixation methods, but it was reached earlier in specimens fixed with screws and later in those fixed with plates as rotation progressed. In this cadaveric Jones fracture model, intramedullary screw fixation demonstrated bending stiffness and resistance to early torsional loading that was superior to that offered by plate fixation. Although low-profile "hook" plates offer an alternative for fixation of fifth metatarsal Jones fractures, intramedullary screw fixation may provide better resistance to bending and initiation of fracture site rotation.

    To investigate the functional and radiographic outcomes of pre-bent elastic stable intramedullary nail in treatment of distal radial shaft fractures in children. From January 2006 to December 2008, 18 children with distal radial shaft fracture were treated by close reduction and internal fixation with a pre-bent elastic stable intramedullary nail. The age range was from 5 years to 15 years, with an average of 9 years and 8 months. The minimum follow-up was 12 months. All fractures maintained good alignment postoperatively, and 94.4% (17/18) of the patients regained a full range of rotation of the forearm. One patient has limitation of rotation to less than 10°, this had improved by final follow-up. Complications included soft tissue irritation at the site of nail insertion in one patient and transient scar hypersensitivity in another. Fixation with a pre-bent elastic stable intramedullary nail is an effective, safe and convenient method for treating distal radial shaft fractures in children. © 2010 Tianjin Hospital and Blackwell Publishing Asia Pty Ltd.

    To compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius. From January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up. Two cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,Pmeaning (t=-1.55, P>0.05). LCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

    The gold standard for fractures of the acetabulum is to perform an open reduction and internal fixation in order to achieve anatomical reduction. In a well-defined subset of patients, percutaneous techniques may be employed but achieving reduction by closed means can be challenging especially for fractures with large degrees of displacement. Such patient may include elderly patients who may not have the physiologic reserve to withstand open approaches. In our paper, we present a new option using laparoscopic assisted reduction of the acetabular fracture and percutaneous fixation. The young obese patient refused all forms of blood products transfusion and presented with a displaced transverse posterior wall fracture. While we do not recommend routine use of such technique and recognize its numerous limitations, we present it as an alternative strategy in a small subset of patients. Copyright © 2016 Elsevier Ltd.

    Full Text Available BACKGROUND Supracondylar fractures of femur have a bimodal distribution. They account for 6% of all femur fractures. Nearly, 50% of distal femur intraarticular fractures are open fractures. Despite many changes and refinements in the surgical treatment of the supracondylar and intercondylar fractures of femur their surgical management remains challenging. Since the introduction of the condylar blade plate to the present retrograde supracondylar nailing and locking condylar plates, these fractures particularly if open and associated with severe fragmentation of the articular cartilage and in the elderly with severe osteoporosis continue to be a major unsolved surgical challenge. Improved imaging facilities rendered surgical results far better than those treated with long periods of traction on bed with accompanying complications. LCP along with isolated 6.5 mm cannulated cancellous screw systems are best suited for with unicondylar fractures of distal femur in young patient with good bone stock. The functional outcome is largely determined by the degree of accompanying soft tissue injury. Presence of a compound fracture leads to a higher incidence of infection. With good preoperative antibiotics and sterile surgical techniques along with stable fixation, infection can be brought under control and a good outcome can be achieved. MATERIALS AND METHODS Thirty supracondylar and intercondylar fractures of femur (Muller’s type ‘A’, type ‘B’ and type ‘C’ fractures, which were treated with open reduction and internal fixation by locking compression plate were included in the study. The study was conducted at the Department of Orthopaedics, King George Hospital, Visakhapatnam, from August 2014 to November 2016. Among 30 patients, 5 patients were lost for follow up due to various reasons leaving 25 fractures from 25 patients for the study. RESULTS There were 16 males and 9 females. Age range was 19 years to 80 years with an average of 44

    Subtrochanteric fractures of the femur are being managed successfully with various intramedullary and extramedulary implants with reasonable success. However, these implants require precise placement under image intensifier guidance, which exposes the surgeon to substantial amount of radiation. It also restricts the management of these fractures at peripheral centers where facility of image intensifiers is not available. Keeping this in mind we designed this study to identify if contralateral reversed distal femoral locking plate can be used successfully without the use of image intensifier. Twenty-four consecutive patients (18 men and 6 women) with a mean age of 28 years (range 19-47 years) suffering subtrochanteric fractures of the femur underwent open reduction and internal fixation with reversed contralateral distal femoral locking plate. The outcome was assessed at the mean follow-up period of 3.2 years (range 2-4.6 years) using the Harris hip score. Twenty-one fractures united with the primary procedure, with a mean time of consolidation being 11 weeks (range, 9-16 weeks). One patient developed superficial suture line infection, which resolved with oral antibiotics. Another patient had a fall 3 weeks after surgery and broke the plate. Repeat surgery with reversed distal femoral locking compression plate was performed along with bone grafting and the fracture united. Two cases had nonunion, which went in for union after bone grafting. The mean Harris hip score at the time of final follow-up was 90.63 (range 82-97). The reversed contralateral distal femoral plate is a biomechanically sound implant, which when used for fixation of the subtrochanteric fractures with minimal soft tissue stripping shows results comparable to those achieved by using other extramedullary implants as well as intramedullary devices. The added advantage of this implant is its usability in the absence of an image intensifier.

    Full Text Available Background Treatment of comminuted fractures of the distal femur and proximal tibia is difficult, and a challenge in the field of orthopedic trauma. Objectives The aim of this study was to assess the short-term results of hybrid external fixation in the treatment of these fractures. Patients and Methods In a prospective study, 44 patients with comminuted fractures of the distal femur or proximal tibia, with an overlying soft tissue injury treated by closed reduction and hybrid external fixation, were included. Parameters such as pin-track infection, union, limb shortening, knee motion, and alignment were evaluated during a mean follow-up period of 14 months. Results Forty-four patients with distal femoral (n = 23 and proximal tibial (n = 21 fractures were treated using hybrid external fixation. Bone union was seen in 35 (80% of the patients. Pin tract infection was seen in three patients (6.8%, one case (4.6% with a PTF and two cases (8% with DFFs. Malunion was observed in 4 patients (9.1%; of these, three cases (13% had DFF and one case (4.8% of pain was detected in the DFF group. One case had malunion and three cases had union. Findings showed satisfactory results in more than 80% of patients. In general, lower postoperative complications were detected in the proximal tibial fractures than the distal femoral fractures. According to a chi-square test, the difference between the patients with PTFs and those with DFFs was not clinically significant. Conclusions Closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation.

    Objective: To determine the frequency of post-operative infection in patients with mandibular angle fractures treated with rigid fixation after extraction of involved third molar. Materials and Methods: In a total of 100 patients undergoing open reduction and internal fixation of mandibular angle fractures in which involved third molar will be extracted were included from Department of Oral and Maxillofacial Surgery, Mayo Hospital, Lahore. Procedure was performed by the same consultant and post operatively patients were assessed by two post graduate trainees who were trained previously to check Infection, on 1st, 2nd, 4th and 6th weeks post operatively. All the observations were entered on preformed proforma. Data was entered and analyzed by using SPSS version 10.0 Results: According to this study, the mean age of patients was 33.22 + 9.155 years. Minimum and maxi-mum age of patients was 18 years and 50 years with range of 32 years. There were 83 (83.0%) male patients while only 17 (17%) female patients presented with mandibular angle fractures. The rate of infection at week 1 was higher (9 (9.0%) cases), but gradually decreased in next follow up. 8 (8.0%) at 2nd week, 7 (7.0%) at week 4 and only 6 (6.0%) in last follow up at week 6 after open reduction and internal fixation of mandibular angle fractures with extraction of third molar. Conclusion: The frequency of post-operative infection in patients with mandibular angle fractures treated with rigid fixation after extraction of third molar was 30% at different follow ups in which 9% patients had infection at first week, 8 patients had at 2nd week, 7 patients had at 6th week and 6% patients presented with infection at last follow up. Overall the infection rate is lower in patients with mandibular angle fractures treated with rigid fixation after extraction of third molar. (author)

    Unstable posterior pelvic ring fractures and dislocations are uncommon but potentially life-threatening injuries in children. Early definitive management reduces risk of immediate complications as well as chronic pain and gait dysfunction. Conventional operative therapy carries substantial risk of extensive blood loss and iatrogenic neurological and vascular injury. Minimally invasive image-guided intervention may further reduce immediate risk and improve long-term outcome. To describe CT-guided closed reduction and internal fixation (CRIF) and review outcomes of unstable fracture-dislocation of the sacroiliac (SI) joint in children. Between 2000 and 2003, three children (two girls, one boy) age 8-14 years were referred to interventional radiology for treatment of unstable SI joint fracture-dislocation not adequately treated with anterior external fixation alone. The three affected SI joints (two left, one right) were treated in a combined approach by pediatric interventional radiologists and orthopedic surgeons, using a percutaneous approach under CT guidance. Over a threaded guiding pin, 7.3 mm cannulated screws were used to achieve stable reduction of the affected SI joints. One screw was removed after slight (2 mm) migration. No neurovascular or other complications occurred. All patients had satisfactory healing with near-anatomic reduction, although recovery of the youngest was delayed by associated spinal injury. Compared to open surgical alternatives, CRIF under CT guidance reduces operating time, decreases blood loss, and allows early definitive fixation and immediate non-weight-bearing mobilization with a low rate of complication for unstable posterior pelvic ring fractures. In addition, CT-guided placement of the guide pin may allow safer screw positioning and may minimize the total number of screws needed to achieve pelvic stability.

    The aim of this study was to compare the fixation effects of three fixation devices for tibial plateau fracture (AO/OTA classification 41 A1). Sixteen human cadaver tibial specimens were randomly divided into four groups. An A1 fracture model was established. The fractures were subsequently fixed by axial controlled intramedullary nail, external fixation and steel plate fixation. Each specimen was subjected to axial compression, torsion test and three-point bending test. Then a rat model was used to evaluate the therapeutic effect of these three fixations by evaluation of callus formation time and healing time. It was found that the axial controlled intramedullary nail group obtained superior biomechanical properties of resistance ability of bending, torsional and axial compressive, compared with external fixation and steel plate group. In animal experiments, the axial controlled intramedullary nail group had a significant shorter callus occurrence and healing time than steel plate and external fixator group. The axial controlled intramedullary nail fixation has a superior biomechanical characteristic and fixation effect for tibial plateau fractures than steel plate and external fixator.

    Full Text Available We believe that a certain subset of surgical ankle fracture patients can be made weight-bearing as tolerated immediately following surgery. Immediate weight-bearing as tolerated (IWBAT allows patients to return to ambulation and activities of daily living faster and may facilitate rehabilitation. A prospectively gathered orthopaedic trauma database at a Level 1 trauma center was reviewed retrospectively to identify patients who had ORIF after unstable ankle injuries treated by the senior author. Patients were excluded if they were not IWBAT based on specific criteria or if they did meet followup requirement. Only 1/26 patients was noted to have loss of fixation. This was found at the 6-week followup and was attributed to a missed syndesmotic injury. At 2-week followup, 2 patients had peri-incisional erythema that resolved with a short course of oral antibiotics. At 6-week followup, 20 patients were wearing normal shoes and 6 patients continued to wear the CAM Boot for comfort. To conclude, IWBAT in a certain subset of patients with stable osteosynthesis following an ankle fracture could potentially be a safe alternative to a period of protected weight-bearing.

    To evaluate perioperative blood loss and blood transfusion requirement in patients who underwent dynamic hip screw plate fixation for a stable trochanteric fracture with or without preoperative intravenous tranexamic acid (TXA). 49 men and 11 women (mean age, 56.5 years) who underwent open reduction and internal fixation with a dynamic hip screw plate for a stable trochanteric fracture by a single surgeon were equally randomised to receive either a single dose of intravenous TXA (15 mg/kg) 15 minutes prior to surgery or an equal volume of normal saline by slow infusion. Intra- and post-operative blood loss and the need for blood transfusion were assessed, as was any thromboembolic adverse event. The TXA and control groups were comparable in terms of age, gender, body mass index, blood pressure, pulse rate, time from injury to surgery, operating time, and preoperative haematological data. Blood loss was lower in the TXA than control group intraoperatively (320.3 vs. 403.33 ml, ptrochanteric fractures.

    2016-10-01

    Full Text Available BACKGROUND The aim of the study is to categorically suggest the apt method of surgical technique for a particular type of distal radius fracture (Frykman’s type III-VI. Distal radius fracture are among the most common fractures of the upper extremity inspite of increased focus on regular prevention of osteoporosis, early identification and its prompt management. Most distal radius fractures are the result of low energy mechanisms that can be successfully treated either nonoperatively or with a variety of operative techniques if indicated. Complex distal radius fractures occur most commonly in high-energy injuries with extensive comminution or bone loss and associated soft tissue or vascular injuries. These high-energy fractures can present challenges in reconstructing the distal radius. Effective restoration of the bony architecture requires a thorough knowledge of distal radius anatomy, understanding of the goals of treatment, versatility in surgical approaches and familiarity with multiple fixation options. Although, majority of the extra-articular fracture without signs of instability can be successfully managed with POP immobilisation for a period of 4-5 weeks followed by active physiotherapy, other types (Frykman’s III-VI need surgical management that too with combination of surgical techniques namely augmented spanning external fixator with supplemented K-wire fixation or external fixation followed by fragment specific volar locking compression plate osteosynthesis. MATERIALS AND METHODS I have studied 50 cases of distal radius fractures classified using Frykman’s classification using combination of techniques namely augmented spanning external fixator application with K-wire supplementation and spanning external fixator application followed by volar LCP fixation in which external fixator had been used as a reduction tool in majority of the cases and external fixator had been removed after plate osteosynthesis.

    Background Intramedullary screw (IMS) fixation was wildly used in fifth metatarsal base fractures (FMBFs) and the results were satisfactory. However, in the comminuted osteoporosis or small displaced avulsion FMBFs, anatomical reduction and stable fixation could not be achieved with IMS. The Locking Compression Plate (LCP) distal ulna hook plate fixation was a novel alternative fixation method. The aim of this retrospective cohort study was to determine if LCP distal ulna hook plate fixation ...

  16. Combined Percutaneous Iliosacral Screw Fixation With Sacroplasty Using Resorbable Calcium Phosphate Cement for Osteoporotic Pelvic Fractures Requiring Surgery.

    2016-06-01

    Osteoporotic sacral fractures, including acute and chronic insufficiency fractures, are increasing in frequency and present a number of management problem. Many of these patients are treated nonoperatively with relative immobility (eg, bedrest, wheelchair, or weight-bearing restrictions) and analgesics, which likely make the osteoporotic component worse. Surgery in this patient population may be desirable in some cases with the goals of improving mobility, relieving pain, and healing in an aligned position while minimizing deformity progression. However, internal fixation of the osteoporotic pelvis can be difficult. Large unicortical lag screws are the workhorse of posterior pelvic fixation, and yet fixation in cancellous bone corridors of an osteoporotic sacrum seems unlikely to achieve optimal fixation. As a result, the operative management and clinical results of these difficult injuries may not be uniformly successful. The authors present a technique for treating osteoporotic patients with a sacral fracture when operative treatment is indicated using percutaneous screw fixation combined with screw augmentation using a resorbable calcium phosphate bone substitute or "cement." The guide wire for a 7.3-mm or other large cannulated lag screw is fully inserted along the desired bony sacral corridor as is standard. The lag screw is then inserted over the wire to the depth where cement is desired. The guide wire is removed, and the aqueous calcium phosphate is injected through the screw's cannulation. For acute fractures, cement was applied to the areas distant to the fracture; whereas in insufficiency fractures, the cement was inserted along most of the screw path. The guide wire then can be reinserted and the lag screw fully inserted. The rationale for using these 2 modalities is their synergistic effect: the cannulated screw provides typical screw fixation and also a conduit for cement application. The cement augments the lag screw's purchase in osteoporotic bone

    Surgical treatment of displaced midshaft clavicle fractures requires a decision between plate fixation and intramedullary (IM) fixation. Numerous studies report on the biomechanical properties of various repair constructs. The goal of this systematic review was to provide an overview of studies describing the biomechanical properties of the most commonly used surgical fixations of midshaft clavicle fractures. Additionally, we aimed to translate these biomechanical results into clinically relevant conclusions. A computer-aided search of the EMBASE and PudMed/MEDLINE databases was conducted. Studies included for review compared biomechanical properties of plate fixation with IM fixation and superiorly positioned plates with anteroinferiorly positioned plates for midshaft clavicle fractures. Fifteen studies were eligible for inclusion. Plate fixation seemed to form a more robust construct than IM fixation in terms of stiffness and failure loading. The remaining clavicle was stronger after removal of the IM device than after removal of the plate. Superior plating of transverse fractures generally seemed to provide greater stiffness and strength during bending loads than anteroinferior plating did. The absence of cortical alignment in wedge and comminuted fractures directly influenced the fixation stability for both IM fixation and plate fixation, regardless of location. Each type of fracture fixation has biomechanical advantages and disadvantages. However, exact thresholds of stiffness for inducing healing and failure strength to withstand refractures are unknown. The clinical relevance of the biomechanical studies may be arguable. Since none of the studies investigate the effect of tissue adaptation over time they should be interpreted with caution.

    The goal of this study was to evaluate the biomechanical performance of three distal fibula fracture fixation implants in a matched pair cadaveric fibula model: (1) a 5-hole compression plate with lag screw, (2) a 5-hole locking plate with lag screw, and (3) the 6-hole tabbed-plate with locking screws. Three-dimensional motions between the proximal and distal fibular segments were measured under cyclic valgus bending, cyclic compressive axial loading, and cyclic torsional external-rotation loading. During loading, strains were measured on the surfaces of each fibula near the simulated fracture site, and on the plate, to assess load transfer. Bone quality was quantified globally for each donor using bone mineral density (BMD) measured using Dual X-ray absorptiometry (DEXA) and locally at the fracture site using bone mineral content (BMC) measured using peripheral quantitative computed tomography (pQCT). Mean failure loads were below 0.2Nm of valgus bending and below 4Nm of external-rotational torque. Mean failure angulation was below 1degree for valgus bending, and failure rotation was below 7degrees for external-rotation. In the compression plate group, significant correlations were observed between bone quality (global BMD and local BMC) and strain in every one of the five locations (Pearson correlation coefficients >0.95, p<0.05). In contrast, in the locking and tabbed-plate groups, BMD and BMC correlated with far fewer strain locations. Overall, the tabbed-plate had similar construct stability and strength to the compression and locking plates. However, the distribution of load with the locking and tabbed-plates was not as heavily dependent on bone quality. Copyright © 2016 European Foot and Ankle Society. Published by Elsevier Ltd.

    External fixation of pediatric lower extremity fractures is usually reserved for severe, open fractures in polytraumatized patients, but it is often the only available treatment option for deployed military surgeons. We analyzed the outcomes and complications of 17 consecutive pediatric long bone fractures treated with external fixation at a Forward Surgical Team facility in an austere environment during Operation Enduring Freedom in Afghanistan during a 12-month period. Treatment consisted of uniplanar external fixation for 12 femoral shaft fractures (11 closed), 4 tibial shaft fractures (all open), and 1 subtrochanteric fracture (closed) in 14 males and 3 females with an average age of 7.4 years. All 17 fractures went on to union with no incidences of refracture. Complications included 1 broken pin and 3 pin site infections treated with wound care and oral antibiotics. In a deployed environment, external fixation is the treatment method of choice for lower extremity fractures by virtue of patient, environment, equipment, and mission factors. This case series validates the usage of a simple, uniplanar external fixator for a variety of open and closed pediatric long bone fractures as evidenced by the successful union rate and low number of complications.

    Postoperative spondylodiscitis is relatively uncommon. This complication is associated with increased cost, and long-term of inability to work, and even morbidity. Although the majority of postoperative spondylodiscitis cases can be well managed by conservative treatment, postoperative spondylodiscitis after internal fixation and those cases that are unresponsive to the conservative treatment present challenges to the surgeon. Here, a review was done to analyze the treatment of postoperative spondylodiscitis with/without internal fixation. This review article suggested that majority of postoperative spondylodiscitis without internal fixation could be cured by conservative treatment. Either posterior or anterior debridement can be used to treat postoperative spondylodiscitis without internal fixation when conservative treatment fails. In addition, minimally invasive debridement and drainage may also be an alternative treatment. In case of postoperative spondylodiscitis after internal fixation, surgical treatment was required. In the cervical spine, it can be well managed by anterior debridement, removal of internal fixation, and reconstruction of the spinal stability by using bone grafting/cage/anterior plate. Postoperative spondylodiscitis after internal fixation is successfully managed by combined anterior debridement, fusion with posterior approach and removal of pedicle screw or extension of pedicle screw beyond the lesion site, in the thoracic and lumbar spine.

    The aim of this study is to investigate the safety and clinical efficacy of minimally invasive manipulative reduction with poking k-wire fixation in the treatment of various types of calcaneal fractures. Between July 2012 and July 2014, a prospective parallel controlled study was conducted on 96 patients with closed calcaneal fractures who were admitted to our institution. These patients were randomly divided into two groups, with 48 in each group. Patients in plate group were treated using open reduction and internal fixation, whereas those of manipulation group were treated with minimally invasive manipulative reduction with poking k-wire fixation. All patients were followed up for six months to assess the postoperative recovery and complications. Kerr's scale was adopted to evaluate the functional recovery of fractured calcaneus. A mean healing duration of 9.48 ± 1.92 weeks was achieved in patients of plate group compared with a healing duration of 9.35 ± 1.66 weeks in those of manipulation group, with no statistical significance (p > 0.05). Complications occurred in 20 cases in plate group versus in seven cases in manipulation group with significant difference (p fracture, among patients with compression fracture and tongue type fracture, > 70% of patients achieved with excellent and good outcomes in both groups with no significant difference in clinical efficacy (p > 0.05). The rate of excellent and good outcomes in Sanders type III compression fractures was lower in manipulation group than in plate group (p fractures, the Kerr's score of tongue type fractures in manipulation group was higher than that in plate group, and comparison within manipulation group showed that the score of tongue type fractures was significantly higher than that of compression fractures (p fractures, the score of tongue type fractures in manipulation group was significantly higher than that in plate group, and the score of compression fractures in plate group was significantly

  2. Emergency department external fixation for provisional treatment of pilon and unstable ankle fractures

    2015-01-01

    Full Text Available Unstable ankle fractures and impacted tibial pilon fractures often benefit from provisional external fixation as a temporizing measure prior to definitive fixation. Benefits of external fixation include improved articular alignment, decreased articular impaction, and soft tissue rest. Uniplanar external fixator placement in the Emergency Department (ED ex-fix is a reliable and safe technique for achieving ankle reduction and stability while awaiting definitive fixation. This procedure involves placing transverse proximal tibial and calcaneal traction pins and connecting the pins with two external fixator rods. This technique is particularly useful in austere environments or when the operating room is not immediately available. Additionally, this bedside intervention prevents the patient from requiring general anesthesia and may be a cost-effective strategy for decreasing valuable operating time. The ED ex-fix is an especially valuable procedure in busy trauma centers and during mass casualty events, in which resources may be limited.

    Assess whether postoperative ankle motion after fixation of a fracture of the tibial plafond, treated with articulated external fixation, leads to a better outcome when compared with similar treatment without postoperative ankle motion. Multicenter randomized trial. Three Level I trauma centers. Fifty-five patients were enrolled and entered into a Web-based database and randomized into 1 of 2 groups. Forty-one patients were evaluated at a 1-year follow-up visit, and 31 were seen at 2 years or longer after injury. Patients were treated with a hinged external fixator and limited internal fixation of the articular surface. They were divided postoperatively into two groups, 1 of which had a locked hinge and the other had a mobile hinge and a motion protocol. A general health status questionnaire, the SF-36 (short-form 36); a joint-specific ankle questionnaire, the Ankle Osteoarthritis Score (AOS); and range of motion (ROM) of the ankle joint. There were no significant differences between the two groups at either follow-up interval in the ankle ROM measurement, the AOS pain and disability scale, or the SF-36 physical component summary (PCS) and mental component summary (MCS) scales. These results indicate that treatment protocols that use long periods of cross-joint external fixation that immobilizes the ankle as definitive treatment result in similar patient outcomes compared to otherwise identical treatment protocols that incorporate and use an articulated hinge for ankle motion. However, the results should be interpreted with caution because the patient numbers were too small to detect potentially meaningful differences in outcomes and the follow-up was too short to assess for differences in the development of arthrosis.

    Several techniques of arthroscopic treatment of tibial spine avulsion fractures have been described in the literature. These techniques include the use of various fixation devices such as screws, K-wires, wiring, sutures, and suture anchors. In this study, we evaluate a new wiring technique for the treatment of these injuries. This technique involves fixation by stainless steel tension wires passed over the fractured spine and tied over a bone bridge. The advantages of this technique are that it aids in reduction, allows for compression of the tibial spine fragment anatomically in its fracture bed, provides stable fixation in difficult comminuted fractures, and allows for early mobilization and weight bearing because of the solid fixation.

    Full Text Available Background/Aims: Open reduction and internal fixation (ORIF is a standard surgical procedure in jaw trauma and in orthognathic surgery. Insertion of screws is a significant risk for accidental tooth root injury with varying outcomes. Contrary evidences are found in literature due to a variety of study designs. This study was undertaken to address the lacunae and possibly estimate the difference in occurrence of tooth damage during or after ORIF between trauma and planned osteotomies. Materials and Methods: In this retrospective study, the data of ORIF in either trauma or orthognathic surgery fulfilling inclusion and exclusion criteria were collected and analyzed. Results: There were 1632 patients fulfilling the inclusion and exclusion criteria and formed the study group, of which 663 were in orthognathic surgery, of whom 210 had bimaxillary orthognathic surgery. In the trauma group, 358 patients had fractures involving both jaws whereas 272 had maxilla alone and 339 had mandibular fractures alone. On comparing the outcome, of the 9073 screws studied, 93.40% were not involved in any contact with the teeth, 6.3% were in category of potential hits (near apices or the root surfaces, and only 0.28% had evidence of root damage with the screws. It is observed that molar and premolar had a significant difference in terms of the type of surgery (P ≤ 0.05 whereas canine (P = 0.75 and incisor (P = 0.67 showed no statistical difference. Conclusion: ORIF when used as mentioned is a safe way for the management of fractures. The incidence of root injury is not uncommon but can be avoided with careful planning and execution.

  9. Open tibial fractures: faster union after unreamed nailing than external fixation.

    1999-10-01

    Unreamed intramedullary nailing is an alternative to external fixation in the treatment of open tibial fractures. We compared a prospective series of thirty-one patients managed with a solid nail with static interlocking without intramedullary reaming, with a retrospective series of thirty-one patients managed by external fixation. The protocol for soft tissue treatment was the same throughout the study period. Most fractures were caused by high energy trauma and included Grade I to III B injuries. The fracture wound infection rate was equal in both groups; there were two deep and three superficial infections in the nail group and three deep and two superficial infections in the external fixation group. In addition, eleven patients in the external fixation group had severe pin track infections. The mean time to union was five months in the nail group and eight months in the external fixation group. The incidence of delayed union was twice as high in the external fixation group as in the nail group. The number of surgical procedures performed to promote union was three times higher in the external fixation group. The malunion rate did not differ between the groups. Although the treatment groups are not fully comparable, the results indicate that intramedullary nailing is superior to external fixation in the treatment of most open tibial fractures.

    Poor screw purchase because of osteoporosis presents difficulties in ankle fracture fixation. The aim of our study was to determine if cortical thickness, unicortical versus bicortical purchase, and bone mineral density are predictors of inadvertent screw stripping and overtightening. Ten paired cadaver ankles (average donor age, 81.7 years; range, 50-97 years) were used for the study. Computed tomography scanning with phantoms of known density was used to determine the bone density along the distal fibula. A standard small-fragment, 7-hole, one-third tubular plate was applied to the lateral surface of the fibula, with 3 proximal bicortical cortical screws and 2 distal unicortical cancellous screws. A posterior plate, in which all 5 screws were cortical and achieved bicortical purchase, was subsequently applied to the same bones and positioned so that the screw holes did not overlap. A torque sensor was used to measure the torque of each screw during insertion (Ti) and then stripping (Ts). The effect of bone density, screw location, cortical thickness, and unicortical versus bicortical purchase on Ti and Ts was checked for significance (P screws were inadvertently stripped and 12% were overtightened. Despite 21% of the screws being stripped or being at risk for stripping, we found no significant predictors to warn of impending screw stripping. Additional work is needed to identify clinically useful predictors of screw stripping. PMID:23569675

    Full Text Available Abstract Hip fractures are a common injury among the elderly. Internal fixation with an intramedullary (IM system has gained popularity for the treatment of intertrochanteric femur fractures. Multiple complications associated with IM fracture fixation have been described, however, we report a rare complication of medial pelvic migration of the lag screw of a short IM nail in a stable construct ten weeks post surgery. The patient was subsequently treated with Lag Screw removal and revision surgery with a shorter Lag Screw and an accessory cannulated screw acting as a de-rotational device. The patient did well with the revision surgery and was able to return to full activities.

    2017-12-01

    This article is a systematic review of the published literature about the biomechanics, functional outcomes, and complications of a locked plate as an external fixator in treating tibial fractures. We searched the PubMed, Ovid Medline, Embase, ScienceDirect, and Cochrane Library databases to retrieve the relevant studies. Studies published in English and Chinese which assessed adult patients and more than 4 cases who had sustained any type of fresh tibial fracture treated with the external locking plate, provided that they reported functional outcomes, range of motion (ROM), union or complication rates, and the biomechanical studies of external locked plating are also included. The electronic search strategy revealed 248 studies, and 2 studies were identified as relevant through manual search of references. Finally, 12 studies were included in this systematic review. These consist of 3 pure biomechanical studies, 8 case series, and 1 study including both of biomechanics and case series. Due to the heterogeneity of biomechanical studies, we can only conclude that external locked plate shows inferior structural stiffness than internal locked plate. The clinical studies reported that external locked plating gave a satisfactory ROM of the knee and ankle, functional outcomes, union rate, and low complication rate. We can only conclude that external locked plate shows inferior structural stiffness than internal locked plate because of the heterogeneity of biomechanical studies. The clinical studies showed locked plating as an external fixator in treating tibial fractures can be considered as a safe and successful procedure. However, as yet, there is unconvincing evidence that it is superior to standard techniques with regards to clinical and functional outcomes. More and well-designed studies about this technique should be carried out.

    2017-06-01

    Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures. From January 2011 to December 2013, 25 displaced acetabular fractures were treated by open reduction and internal fixation. The fractures were managed using a Kocher-Langenbeck approach along with trochanteric flip osteotomy. At 3rd, 6th and 24th month follow-up, all patients had radiographic examination and underwent a final clinical evaluation based on the modified Merle d'Aubigne and Postel score. The strength of the abductors was assessed according to the Medical Research Council (MRC) grading system. Congruent reduction was achieved in all patients and all osteotomies healed within an average period of 3.8 months. All our patients were allowed full weight bearing at the end of 3 months and with no abductor lurch at the end of 6 months follow-up. There were no cases of avascular necrosis of femoral head. None of the patients had any neurovascular complication or infection by the end of the follow-up period. Trochanteric flip osteotomy is a very effective technique to fix certain acetabular fractures especially those with dome involvement. It is more accurate and associated with no significant complications compared with conventional way.

    2016-01-01

    The present study compared the quality of reduction and the clinical assessment between screw fixation and suture-button fixation with an ankle fracture accompanied by syndesmosis injury. We studied the clinical and radiologic findings 1 year postoperatively through retrospective examination of 24 patients who had undergone screw fixation from January 2011 to December 2012 and prospective examination of 20 patients who had undergone suture button fixation from January 2013 to May 2014. Regarding the tibiofibular clear space, tibiofibular overlap, and medial clear space, the screw fixation group had improvement from a preoperative mean of 6.97 (range 2.79 to 15.81) mm, 4.43 (range 0 to 7.87) mm, 7.90 (range 4.24 to 19.50) mm to a postoperative mean of 4.95 (range 2.72 to 9.08) mm, 6.29 (range 0 to 10.37) mm, and 4.32 (range 1.98 to 6.57) mm, respectively. The corresponding improvement for the suture-button fixation group was from a preoperative mean of 6.65 (range 3.94 to 13.73) mm, 5.39 (range 0 to 9.44) mm, 7.27 (range 4.04 to 16.00) mm to a postoperative mean of 5.15 (range 2.93 to 7.30) mm, 7.21 (range 2.15 to 10.30) mm, and 4.25 (range 2.97 to 5.71) mm. No statistically significant difference was found between the 2 techniques. Both suture-button and metal screw fixation are effective treatment methods for an ankle fracture accompanied by syndesmosis injury. However, a long-term and prospective analysis is needed.

    2011-12-01

    In developing countries, Ilizarov or AO external fixator is usually used for treatment of tibial open fractures. The purpose of this study was to compare the efficacy of these two methods for treatment of tibial open fractures. From April 2002 to April 2010, 120 patients with open tibial fractures admitted to the Department of Orthopedics of Babol University of Medical Sciences entered this study. In each arm, 60 subjects randomly received Ilizarov or AO external fixator. All patients were followed at least for one year. These two groups were compared regarding non-union, malunion and cure rates. The mean age of the patients in Ilizarov group was 32.35±11.28 and for AO were 31.3±10.99 years. Mean time for union in Ilizarov group was 5.25±1.85 and for AO external fixator was 5.85±2.13 months. Nonunion rate in Ilizarov group was 10% and for AO external fixator was 11.7%. Malunion rate in Ilizarov group was 10% and for AO external fixator was 18.3%. Totally, efficacy of treatment in the Ilizarov group was 81.7% and in AO external fixator was 65%. The efficacy of treatment in Ilizarov was higher than that AO external fixator in treatment of open tibial fractures.

    The authors presents the results of healing status of tibia diaphysis fractures treated with carbon-plate fixator on a group of 12 patients (9 men and 3 women with age between 27 and 89 years). Long-term mechanical investigations and studies at animals, performed at our Department have shown advantages of bone fixation performed with a new device for osteosynthesis, called by authors CARBOELASTOFIX. General principle of the method is the use of external fixation device, made of carbon-epoxide resin composite plates with variable flexibility, enabling hastened fracture healing. The research allowed also to work out the guidelines of indications for surgery, surgical technique and method of modifying flexibility of fixation consistently with fracture healing course. The mean time of observation (from the operation to the healing) was 23 weeks, having 10 good and 2 bad results.

    2010-03-01

    Full Text Available Abstract The locking compression plate (LCP is an angle-stable fixator intended for intracorporeal application. In selected cases, it can be applied externally in an extracorporeal location to function as a monolateral external fixator. We describe one patient with Schatzker V tibial plateau fracture and one patient with Gustillo IIIB open tibia shaft fracture treated initially with traditional external fixation for whom exchange fixation with externally applied LCPs was performed. The first case went on to bony union while the second case required bone grafting for delayed union. Both patients found that the LCP external fixators facilitated mobilization and were more manageable and aesthetically acceptable than traditional bar-Schanz pin fixators.

    2016-03-01

    Mandibular fractures represent a substantial portion of facial fractures in the pediatric population. Pediatric mandibles differ from their adult counterparts in the presence of mixed dentition. Avoidance of injury to developing tooth follicles is critical. Simple mandibular fractures can be treated with intermaxillary fixation (IMF) using arch bars or bone screws. This report describes an alternative to these methods using silk sutures and an algorithm to assist in treating simple mandibular fractures in the pediatric population. A retrospective chart review was performed and the records of 1 surgeon were examined. Pediatric patients who underwent treatment for a mandibular fracture in the operating room from 2011 to 2015 were identified using Common Procedural Terminology codes. Data collected included age, gender, type of fracture, type of treatment used, duration of fixation, and presence of complications. Five patients with a mean age of 6.8 years at presentation were identified. Fracture types were unilateral fractures of the condylar neck (n = 3), bilateral fractures of the condylar head (n = 1), and a unilateral fracture of the condylar head with an associated parasymphyseal fracture (n = 1). IMF was performed in 4 patients using silk sutures, and bone screw fixation was performed in the other patient. No post-treatment complications or malocclusion were reported. Average duration of IMF was 18.5 days. An algorithm is presented to assist in the treatment of pediatric mandibular fractures. Silk suture fixation is a viable and safe alternative to arch bars or bone screws for routine mandibular fractures. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

    (1) Compare the outcomes of patients with orthopaedic trauma with culture-negative infection with those with pathogens identified; (2) identify the incidence of culture-negative infection and describe the common characteristics. Retrospective study. Two level 1 trauma centers. A total of 391 patients 16 years of age or older who underwent irrigation and debridement for surgical site infection after having undergone fracture fixation were included. Patients underwent irrigation and debridement with cultures, and antibiotic therapy was initiated. Treatment failure due to unsuccessful eradication of infection and time to union. We found 9% incidence of culture-negative infection. Approximately one-third of patients in both groups went on to have treatment failure (25% of pathogen-specific infections, 38% of culture-negative infections, P = 0.15), and there was no difference between the 2 groups with regard to time to union (22 vs. 24 weeks, P = 0.55). More than one-third of patients required subsequent reconstructive procedure and 5% of patients in each group required amputation to control their infection. There was no difference between the groups with respect to the use of antibiotics before intervention and culture. This study confirms the devastating effect that postoperative infections can have and suggests that, with clinical sign of infection, negative cultures do not portend a better prognosis. These entities should be treated in a similar manner to infections with positive cultures. Furthermore, we believe that future studies should not strictly rely on the presence of positive intraoperative cultures. Consensus as to what constitutes a clinical infection, in the absence of positive cultures, is needed. Prognostic Level III.

    The aim of the present randomized study was to evaluate the efficacy of intermaxillary fixation screw (IMFS) versus eyelet interdental wiring for intermaxillary fixation (IMF) in minimally displaced mandibular fractures. A total of 50 patients with a minimally displaced mandibular fracture were enrolled, with 25 patients randomly selected for each group. In group I (study group, n = 25), the patients were treated using IMFS, and in group II (control group, n = 25), they received eyelet interdental wiring. Both techniques were assessed for the following parameters: time required for placement and removal of each type of IMF technique, time required for placement of IMF wires, postoperative occlusion, stability of the IMF wire, local anesthesia requirement during removal of each fixation type, oral hygiene status, glove perforation rate, and complications associated with both techniques. The collected data were analyzed using Student's unpaired t test or χ2 test. P wire in group I was 2.1 minutes and in group II was 6 minutes. The oral hygiene status was assessed, and the mean plaque index score for groups I and II was 1.44 and 2.12, respectively (P = .00). The glove perforation rate was much less in group I than in group II. Finally, the most common complication in both groups was mucosal growth. The results established the supremacy of IMFS compared with eyelet interdental wiring. Thus, we have concluded that IMFS, in the present scenario, is a safe and time-saving technique. IMFS is a cost-effective, straightforward, and viable alternative to cumbersome eyelet interdental and other wiring techniques for providing IMF, with satisfactory occlusion during closed reduction or intraoperative open reduction internal fixation of fractures. In addition, oral hygiene can be maintained, and the glove perforation rate was very low using IMFS. The relatively small sample size and limited follow-up period were the study limitations.

    A biomechanical comparison of fixation constructs in an experimental fracture model. To determine the relative postoperative stability of anterior graft and plating with that of posterior or combined fixation constructs in an unstable thoracolumbar burst fracture model. Several treatment modalities have been proposed for unstable thoracolumbar burst fractures, but the optimal technique is unclear. Previous cadaveric biomechanical studies in unstable burst fracture models have not considered the commonly used posterior (interpedicular) and anterior (plate) constructs. Nine human spine segments (T11-L3) were potted in epoxy and scanned using dual energy x-ray absorptiometry and computed tomography. Intact specimens had baseline flexibility testing. Unstable L1 burst fractures as verified by computed tomography were created using an impulse load and posterior surgical osteoligamentous destabilization (ie, transection of the lamina, interspinous ligaments, facet capsules, and ligamentum flavum). Specimens were instrumented posteriorly with pedicle screws and rods and tested to 6 Nm in flexion-extension, lateral bending, and torsion. Corpectomy and strut grafting were then performed, and testing was repeated in varying order with posterior fixation, anterior plating and circumferential fixation. Range of motion (ROM) and neutral zone was calculated for each test and fixation groups were compared using analysis of variance. All specimens had AO B1.2 (unstable burst) fractures. Mean ROM for posterior-only constructs was significantly less than that of the intact in lateral bending, flexion, and extension (Pbending (Ptorsion (all at Ptorsion. Increased ROM was correlated with greater fracture comminution for posterior-only fixation (P<0.05), and was weakly correlated with lower dual energy x-ray absorptiometry score (R=0.3) for anterior-only fixation. Circumferential instrumentation provided the most rigid fixation, followed by posterior fixation with anterior strut

    The current study evaluated the success and the possible complication of intermaxillary fixation with self-tapping and self-drilling screws (STSDSs) in nondislocated or slightly dislocated mandibular fractures.Forty patients with mandibular fractures, treated with intermaxillary fixation using STSDSs, were clinically assessed by means of a dental vitality test and evaluation of tooth mobility adjacent to the cortical screw holes, and radiologically by means of a panoramic dental radiograph upon removal of the screws.The main complication was screw loss in 4.4% of cases, followed by coverage by oral mucosa in 1.2% of cases. However, no dental root damage, screw breakage, malocclusion, or poor consolidation of mandibular fractures was observed.The use of STSDSs for intermaxillary fixation is a useful alternative to the use of arch bars in the treatment of some types of mandibular fractures. In addition, there is no risk of dental lesions as with self-tapping screws.

    Full Text Available An articular glenoid fracture is an uncommon injury. Usually significantly displaced intra-articular glenoid fractures are treated with open reduction surgery. Conventional open surgery techniques involve high morbidity. Here we describe an arthroscopy-assisted reduction and fixation method of an Ideberg type III glenoid fracture. This method provides good articular reduction without extensive exposure or soft tissue dissection and without nerve and/or vascular lesion.

    This is a retrospective, clinical, and radiologic study of posterior reduction and fusion of the C1 arch in the treatment of unstable Jefferson fractures. The aim of the study was to describe a new motion-preserving surgical technique in the treatment of unstable Jefferson fracture. The management of unstable Jefferson fractures remains controversial. The majority of C1 fractures can be effectively treated nonoperatively with external immobilization unless there is an injury to the transverse atlantal ligament (TAL). Conservative treatment usually involves immobilization for a long time in Halo vest, whereas surgical intervention generally involves C1-C2 fusion, eliminating the range of motion of the upper cervical spine. We propose a novel method for the treatment of unstable Jefferson fractures without restricting the range of motion. A retrospective review of 12 patients with unstable C1 fractures between April 2008 and October 2011 was performed. They were treated by inserting bilateral posterior C1 pedicle screws or lateral mass screws interconnected by a transversal rod to achieve internal fixation. There were 8 men and 4 women, with an average age of 35.6 years (range, 20-60 y). Presenting symptoms included neck pain, stiffness, and decreased range of motion but none had neurological injury. Seven patients had bilateral posterior arch fractures associated with unilateral anterior arch fractures (posterior 3/4 Jefferson fracture, Landells type II), and 5 had unilateral anterior and posterior arch fractures (half-ring Jefferson fracture, Landells type II). Seven patients had intact TAL, and 5 patients had fractures and avulsion of the attachment of TAL (Dickman type II). A total of 24 screws were inserted. Five cases had screws placed in the lateral mass: 3 because of posterior arch breakage, and 2 because the height of the posterior arch at the entry point was Jefferson fractures, which allows preservation of the function of the craniocervical junction

    Repair of a Salter-Harris type IV dicondylar humeral fracture was performed on a 15-week-old pitbull terrier. Interfragmentary compression of the intracondylar component of the fracture was achieved with a transilial rod and locking nuts (Trans-ilial Rod; IMEX Veterinary, Inc.). The transilial rod was articulated with a modified type I external fixator which functioned as adjunctive stabilisation for the supracondylar component of the fracture. Fracture healing was confirmed radiographically five weeks following surgery. The dog had no appreciable lameness when examined 12 months after fracture repair.

    The results of treatment of fractures of the femoral shaft with static interlocking nailing were reviewed retrospectively to determine the clinical importance of any stress-riser or stress-shielding properties of the nail. These properties, if relevant, would have been manifested by refracture of the femur, either through a hole used for a locking screw or through the original site of fracture after extraction of the device. Two hundred and fourteen fractures that had been treated with static interlocking nailing and that had healed without conversion to dynamic intramedullary fixation were divided into two groups. In Group I, which comprised 111 fractures, the static interlocking-fixation device was retained and in Group II, which comprised 103 fractures, the static interlocking-fixation device was removed during one operative procedure at an average of fourteen months after the injury. The average duration of follow-up was thirty months from the time of the original fixation in both groups. All patients in Group II were followed for a minimum of six months after removal of the nail. No femur in Group I, in which the static interlocked nail remained in situ, refractured. No femur in either group fractured through the proximal or the distal holes used for the locking screws. No locking screws or nails broke. One patient (1 per cent) in Group II had a refracture of the femoral shaft through the site of the original fracture six weeks after removal of the nail.(ABSTRACT TRUNCATED AT 250 WORDS)

    In cases of displaced greater tuberosity fractures, treatments by arthroscopic-assisted reduction and percutaneous screw fixation have been reported. However, in cases in which there is a comminuted fracture or a minimally displaced fracture combined with concomitant lesions such as rotator cuff tear or labral pathology, it is difficult to reduce the fracture and to treat other pathologies by use of a percutaneous screw. Recently, many surgeons have used the double-row repair method in rotator cuff repair, which provides a tendon-bone interface better suited for biologic healing and restoring normal anatomy. In accordance with this method, we used the arthroscopic technique of double-row suture anchor fixation for a minimally displaced greater tuberosity fracture without additional incision. Initially, debridement was performed on the fracture surface by use of a shaver, and the medial-row anchor was inserted through the anterior portal or the intact cuff. Two lateral-row anchors were inserted just anterior and posterior to the lower margin of the fractured fragment under C-arm guidance. The medial-row sutures and lateral-row sutures were then placed. Arthroscopic double-row suture anchor fixation of a displaced greater tuberosity fracture restores the original footprint of the rotator cuff and normal tendon-bone interface of the displaced greater tuberosity fracture.

    2010-06-01

    Full Text Available Objectives: Intracapsular femoral neck fractures have been found as associated with hemarthrosis. The fluid in the intact capsule elevates the intracapsular pressure to a level could tamponades the vascular supply of the femoralhead. Therefore, capsular decompression seems necessaryto salvage the femoral head circulation. Negative impact of the capsular incision also has been reported. Therefore, we hypothesize that creation of a trans-osseousportal can decompress the capsule as well as not threaten the capsular related blood vessels.Materials and methods: In present study, 27 patients with intracapsular femoral neck fractures were included. Coinciding with closed reduction and internal fixation we made a trans-osseous portal for capsular decompression. Patients were followed-up prospectively for a mean periodof 43.1 months.Results: All fractures united. However, one patient 17 years-old who was nursed preoperatively in skin traction developed osteonecrosis of the femoral head.Conclusion: Our results supported that the trans-osseous capsular decompression has evacuated the intracapsular haematoma and has not threatened the capsular integrity. Preoperative traction of the injured limb particularly in the young patient may play a role in development of osteonecrosisof the femoral head.

    Full Text Available Background: Over the years, there has been a tremendous increase in the use of fluoroscopy in orthopaedics. The risk of contracting cancer is significantly higher for an orthopedic surgeon. Hip and spine surgeries account for 99% of the total radiation dose. The amount of radiation to patients and operating surgeon depends on the position of the patient and the type of protection used during the surgery. A retrospective study to assess the influence of the radiation exposure of the operating surgeon during fluoroscopically assisted fixation of fractures of neck of femur (dynamic hip screw and ankle (Weber B was performed at a district general hospital in the United Kingdom. Materials and Methods: Sixty patients with undisplaced intertrochanteric fracture were included in the hip group, and 60 patients with isolated fracture of lateral malleolus without communition were included in the ankle group. The hip and ankle groups were further divided into subgroups of 20 patients each depending on the operative experience of the operating surgeon. All patients had fluoroscopically assisted fixation of fracture by the same approach and technique. The radiation dose and screening time of each group were recorded and analyzed. Results: The radiation dose and screening time during fluoroscopically assisted fixation of fracture neck of femur were significantly high with surgeons and trainees with less than 3 years of surgical experience in comparison with surgeons with more than 10 years of experience. The radiation dose and screening time during fluoroscopically assisted fixation of Weber B fracture of ankle were relatively independent of operating surgeon′s surgical experience. Conclusion: The experience of operating surgeon is one of the important factors affecting screening time and radiation dose during fluoroscopically assisted fixation of fracture neck of femur. The use of snapshot pulsed fluoroscopy and involvement of senior surgeons could

    To evaluate the effect of posterior bony versus ligamentous injury pattern on functional outcomes in operatively treated rotational ankle fractures. Retrospective cohort analysis of prospective registry. Academic Level I trauma center. Operatively treated supination external rotation IV and pronation external rotation IV ankle fractures. Lateral malleolus plate fixation with either posterior malleolus (PM) plate fixation or posterior inferior tibiofibular ligament (PITFL) repair. Foot and ankle outcome scores at minimum 12 months postoperatively. One hundred seventy-eight fractures were treated with injury-specific anatomic fixation of a PM fracture (n = 122) or torn PITFL (n = 56). The PM group was significantly older, contained more women, and had lower mean body mass index versus the PITFL group. There was a higher rate of medial malleolar fracture in the PM group; other fracture and baseline characteristics were similar between groups. Univariate and multivariable analysis revealed no difference in foot and ankle outcome scores for any of the 5 summary domains (symptoms, pain, activities of daily living, sports, or quality of life) at the time of most recent follow-up. The median length of follow-up was 16.3 and 12.8 months in the PM and PITFL groups, respectively. In our cohort of ankle fractures, we have demonstrated comparable outcomes in stage IV rotational ankle fractures with and without PM fractures, indicating that the presence of a PM fracture may not result in inferior outcomes compared with ligamentous equivalent injuries if these fractures are addressed in an injury-specific manner.

    2015-08-01

    The purpose of this study was to evaluate the efficacy of routine postoperative computed tomography (CT) scan after open reduction and internal fixation of acetabular fractures. Retrospective review of prospectively collected acetabulum fracture database. Level I trauma center. A total of 606 consecutive patients underwent surgical fixation of 612 acetabular fractures. All patients were evaluated with intraoperative fluoroscopy in addition to 3 standard plain radiographs (AP pelvis and two 45 degrees oblique Judet views). Reduction and fixation were believed to be adequate and definitive before exiting the operative suite based on these imaging modalities. Axial postoperative CT scan of the pelvis was obtained in 563 of the patients (93%) after 569 operative cases. Revision acetabular surgery based on routine postoperative CT scan findings. There were no significant differences between index and revision surgery groups regarding age, gender, body mass index, fracture pattern, mechanism of injury, or surgical approach (P > 0.05). Evaluation of 563 postoperative CT scans of the pelvis resulted in revision acetabular surgery for 2.5% of patients (n = 14). There were 6 (1.1%) cases of intraarticular hardware not recognized on the intraoperative fluoroscopy or pelvic radiographs. Four patients (0.7%) had residual intraarticular osteochondral fragments deemed too large to leave in the hip joint. There were 3 cases (0.5%) of unacceptable malreduction, and 1 case (0.2%) of both malreduction and an intraarticular osteochondral fragment. A small percentage of patients (2.5%) will benefit from a routine CT scan after acetabular fracture fixation. Therapeutic Level IV.

    Surgical management of comminuted posterior wall acetabular fractures with marginal fragments remains difficult. The purpose of this study was to evaluate the use of spring plates as adjunctive fixation in comminuted posterior wall acetabular fractures. A retrospective review of patients treated for posterior wall acetabular fractures with the use of customized spring plates as adjunctive fixation between 2000 and 2017 was performed. Patients were evaluated radiographically according to the grading criteria of Matta. Complications including subsequent revision surgery and hardware failure were recorded. Fifty-two patients underwent surgical fixation of posterior wall acetabular fractures with the use of customized 3.5-mm spring plates combined with posterior buttress compression plating over the spring plates as definitive fixation. Mean follow-up was 13.9 months (range: 3-140 months). Forty-two patients had radiographic grades of excellent, with 6 good, 1 fair, and 3 poor. There were no hardware complications. Five patients underwent revision surgery, including 4 patients (7.7%) who underwent a total hip arthroplasty due to advanced arthritis. The use of customized spring plates is a viable method of adjunctive fixation for comminuted posterior wall fractures with marginal fragmentation. Therapeutic Level IV.

  18. Intraocular pressure variations during zygomatic fracture reduction and fixation: a clinical study.

    LENUS (Irish Health Repository)

    Murray, Dylan J

    2012-02-03

    BACKGROUND: The reduction of midface fractures has been associated with the rare but devastating complication of blindness. An increase in intraocular pressure is important in the mechanism of blindness in this setting. In this study, the authors assessed the intraocular pressure in patients who underwent zygomatic fracture reduction (with or without fixation). METHODS: Using applanation tonometry, 29 patients underwent intraocular pressure measurements before, during, and after fracture fixation. The contralateral pressures were measured and used as the control. RESULTS: There were 29 patients with a mean age of 35 years, and the mean time to surgery was 5 days. Preoperatively, all patients had normal intraocular pressures and normal visual acuity. All patients underwent a Gillies lift and 18 patients required open reduction and fixation of the frontozygomatic suture (n = 4) or the infraorbital margin (n = 2), and the remainder (n = 12) required fixation of both points. There was no statistically significant increase in the intraocular pressures following the reduction of uncomplicated zygomatic fractures. Statistically significant pressure reductions were noted immediately after reduction and fixation. CONCLUSIONS: The surgical reduction of uncomplicated zygomatic fractures has no adverse effect on the intraocular pressure. It is the authors\\' opinion that adjunctive measures to reduce the pressures are unnecessary.

    There are no reports on the configuration of equine central tarsal bone fractures based on cross-sectional imaging and clinical and radiographic long-term outcome after internal fixation. To report clinical, radiographic and computed tomographic findings of equine central tarsal bone fractures and to evaluate the long-term outcome of internal fixation. Retrospective case series. All horses diagnosed with a central tarsal bone fracture at our institution in 2009-2013 were included. Computed tomography and internal fixation using lag screw technique was performed in all patients. Medical records and diagnostic images were reviewed retrospectively. A clinical and radiographic follow-up examination was performed at least 1 year post operatively. A central tarsal bone fracture was diagnosed in 6 horses. Five were Warmbloods used for showjumping and one was a Quarter Horse used for reining. All horses had sagittal slab fractures that began dorsally, ran in a plantar or plantaromedial direction and exited the plantar cortex at the plantar or plantaromedial indentation of the central tarsal bone. Marked sclerosis of the central tarsal bone was diagnosed in all patients. At long-term follow-up, 5/6 horses were sound and used as intended although mild osteophyte formation at the distal intertarsal joint was commonly observed. Central tarsal bone fractures in nonracehorses had a distinct configuration but radiographically subtle additional fracture lines can occur. A chronic stress related aetiology seems likely. Internal fixation of these fractures based on an accurate diagnosis of the individual fracture configuration resulted in a very good prognosis. © 2015 EVJ Ltd.

    Leandro Almeida Rui

    Full Text Available ABSTRACT Orthopedic conditions, such as bone fractures, are very common in avian medicine. External fixators have been considered the gold standard for birds, since they allow early movement of the limbs and minimal invasive surgery. Fractures in several bones have been successfully treated in pigeons. However, to the best of our knowledge, this case represents the first report of successful surgical repair of tarsal-metatarsal fracture in rock pigeon. External fixator was made with four 24G catheters, being inserted manually proximal and distal to the fracture and connected with polymerizable acrylic. Radiographic consolidation of fracture was observed 60 days post-surgery and anti-inflammatory and antibiotic protocols were successful on avoiding pain and infection during surgery and bone healing.

    Subcapital femoral neck fractures are a rare complication after fixation of an intertrochanteric fracture with a proximal femoral nail. We report 2 such cases where the patients had severe osteoporosis, based on Singh's index and pathological findings. In one case there was a technical error leading to a tip-apex distance of more than 20 mm, but osteoporosis appeared to be a more significant cause than any technical problems.

    Full Text Available Background: Pelvic ring injuries and sacroiliac dislocations have significant impacts on patient’s quality of life. Several techniques have been described for posterior pelvic fixation. The current study has been designed to evaluate the spinopelvic method of fixation for sacroiliac fractures and fracture-dislocations.   Methods: Between January 2006 and December 2014, 14 patients with sacroiliac joint fractures, dislocation and fracture-dislocation were treated by Spinopelvic fixation at Shahid Sadoughi Training Hospital, Yazd, Iran. Patients were seen in follow up, on average, out to 32 months after surgery. Computed tomographic (CT scans of patients with sacral fractures were reviewed to determine the presence of injuries. A functional assessment of the patients was performed using Majeed’s score. Patient demographics, reduction quality, loss of fixation, outcomes and complications, return to activity, and screw hardware characteristics are described Results: The injury was unilateral in 11 (78.5% patients and bilateral in 3 (21.5%. Associated injuries were present in all patients, including fractures, dislocation and abdominal injuries. Lower limb length discrepancy was less than 10 mm in all patients except two. Displacement, as a measure of quality of reduction was less than 5 mm in 13 patients. The mean Majeed score was 78/100. Wound infection and hardware failure were observed in 3 (21.4% and 1 (7.1% cases, respectively. In this study most patients (85% return to work postoperatively. Conclusion: According to the findings, spinopelvic fixation is a safe and effective technique for treatment of sacroiliac injuries. This method can obtain early partial to full weight bearing and possibly reduce the complications.

    For noncomminuted talar neck fractures, traditional fixation is with small fragment screws or cannulated screws. Newer screw systems on the market allow placement of cannulated headless screws, which provide compression by virtue of a variable-pitch thread. The headless construct has an inherent advantage, particularly for the talus, when the screws must be countersunk to prevent wear of the joint articular surfaces. This study tested the biomechanical fixation strength of cannulated headless variable-pitch screws compared with conventional cannulated screws, both placed in an anterior to posterior direction. A reproducible talar neck fracture was created in nine paired, preserved, cadaver talar necks using a materials testing machine. Talar head fixation was then performed with two cannulated headless variable-pitch 4/5 screws or two 4.0-mm conventional cannulated screws. The specimens were tested to failure and the fixations were normalized to their intact pairs and compared. The headless variable-pitch screw fixation had significantly lower failure displacement than the conventional screw fixation. No significant differences were found between the two fixations for failure stiffness, load at failure or energy absorbed. Cannulated headless variable-pitch screws significantly improved failure displacement when compared to conventional cannulated screws in a cadaveric model, and may be a viable option for talus fracture fixation. Headless, fully threaded, variable-pitch screws have inherent advantages over conventional screws in that they may be less damaging to the articular surface and can compress the fracture for improved reduction. This study demonstrates these screws are also biomechanically similar to conventional screws.

  7. Research on Transverse Acetabular Fracture Fixation Using Different Plate Attachment Methods

    Full Text Available The article deals with the problem of transverse acetabular fracture fixation using different plate attachment methods. A 3D model of pelvis and hip joint structure was created and the design of three different fixation plates using SolidWorks was made. The plates were fixed at distances of 10, 20 and 30 mm from the acetabulum. The model was meshed into finite elements, a static external load of 2500 N was added and the analysis of stress distribution in plates and fracture displacement was performed. The obtained results showed that fracture displacement was quite similar in all fixation methods. However, the maximal stress in the nearest from the acetabulum plate was higher than yield strength. Thus, this placement is not eligible. The plate fixed at a distance of 30 mm from the acetabulum appeared the most suitable because of the smallest and symmetrical stress distribution in the plate.

  8. A simplified application (APP) for the parametric design of screw-plate fixation of bone fractures.

    Screw and plate fixation is commonly used to treat bone fractures. A prototype application (APP) for presurgical simulation was developed and validated by comparing it with current analytical approach and other models. In this APP, alternative plate designs and materials to limit the effects of stress shielding could be tested. In addition, the number and position of screws and the gap between bone and plate that achieved acceptable stability were predicted. The fixation stability providing a situation of interfragmentary strain between 2% and 10% is necessary for callus formation. However, improving the fixation stability leads to a stress shielding effect. The simultaneous alleviation of stress shielding and maintenance of stability are important in fracture healing. In this study, the feasibility of creating a specialized APP to evaluate different screw-plate configurations for diaphyseal femoral fractures was investigated. The ultimate goal is to extend this technique to computer-assisted preoperative planning for orthopedic surgery. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Robot assisted fracture reduction of femoral shaft fractures provides precise alignment while reducing the amount of intraoperative imaging. The connection between the robot and the fracture fragment should allow conventional intramedullary nailing, be minimally invasive and provide interim fracture stability. In our study we tested three different reduction tools: a conventional External Fixator, a Reposition-Plate and a Three-Point-Device with two variations (a 40 degrees and a 90 degrees version). We measured relative movements between the tools and the bone fragments in all translation and rotation planes. The Three-Point-Device 90 degrees showed the smallest average relative displacement and was the only device able to withstand the maximum applied load of 70 Nm without failure of any bone fragment. The Three-Point-Device 90 degrees complies with all the stipulated requirements and is a suitable interface for robot assisted fracture reduction of femoral shaft fractures.

    Although intramedullary headless screw (IMHS) fixation is a promising minimally invasive surgical treatment option for unstable proximal phalanx fractures, a single IMHS may provide inadequate fixation for certain fracture patterns. The purpose of this study was to evaluate the short-term clinical outcomes in a pilot series of patients with proximal phalanx fractures treated with dual antegrade IMHS fixation. We performed a retrospective chart review of proximal phalanx fractures treated with dual antegrade IMHS fixation with a minimum 1 year of follow-up. Demographic information including patient age, sex, occupation, workers' compensation status, mechanism of injury, hand dominance, and injured digit were obtained. Postoperative outcomes measured included range of motion, grip strength, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome scores, return to full-duty work interval, and complications. Ten fractures in 10 patients (4 male, 6 female) satisfied study inclusion. The mean age of patients was 39 years (range, 20-62), and average follow-up duration was 84 weeks (range, 61-106). Final postoperative total active motion was 258° (range, 245°-270°), mean grip strength was 97% (range, 84%-104%) of the uninjured side, and QuickDASH score was 3.9 (range, 0-13.6). No complications occurred, and no patients required additional intervention. Dual antegrade IMHS fixation of proximal phalanx fractures resulted in excellent postoperative motion, near-normal grip strength, positive self-reported patient outcomes, and no complications with follow-up of at least 1 year. Further study in a larger number of patients is warranted to determine if this promising technique is superior to other modes of fixation.

    A six-month-old, male Bernese Mountain Dog in which radius-ulna and tibia-fibula concomitant fractures were treated each with a 3.5 mm Locking Compression Plate (LCP) is presented. Both fractures were approached and plated medially. The tibial fracture had to be revised with a 4.5 mm intramedullary nail and a new 3.5 mm LCP at the second post-operative day because of fixation breakdown. The follow-up radiographs taken at days 14 and 53 revealed uneventful healing of both fractures. Implants were removed 53 days after surgery.

    Displaced fractures of the lateral malleolus are typically treated with plate osteosynthesis with or without the use of lag screws, and immobilisation in a plaster cast for up to 6 weeks. Fixation through a smaller incision with less metal, such as lag screw only fixation, would theoretically lead to decreased infection rates and less irritation caused by hardware. The purpose of this study was to evaluate the benefits and success of lag screw only fixation of the lateral malleolus in non-com...

    Multiple methods have been described for treating unstable proximal and middle phalangeal fractures. Irrespective of using an open or closed technique of fixation, stiffness and extensor lag at the proximal/distal interphalangeal joint almost always occur. This issue can be avoided by allowing the patients to mobilize the fingers out of plaster or splint as early as possible from the day of surgery. We describe a technique of intramedullary percutaneous fixation of extra-articular proximal and middle phalanx fractures allowing immediate mobilization of fingers, concurrent stabilization with progressive healing and thus preventing such complications.

    Full Text Available The number of hip fractures in the elderly growth with the increase in life expectancy. Therefore meet with a femur fractured, distal to a previously  implant fixation used in intertrochanteric femur fractures as dynamic hip screw or fixed angle plate, is not an uncommon scenario despite year mortality of hip fracture of 30 to 50%. Given this situation, we used a retrograde intramedullary nail associated with extracting screws percutaneously prior implant. We present 8 cases in patients with an average age of 85.6 years, 5 female and 3 male with a time from the proximal femur fixation to the  new fracture average 3.5 years. Will we track 36 months and we evaluated postoperative mobility and pain getting a consolidation of the fracture in all cases. We found this technique effective; capable of achieving stable fixation without adding morbidity due to the possibility of overlapping two implants decreasing the possibility of potential new interimplantes fracture.

    Full Text Available Cannulated screw fixation is a widely accepted surgical method for management of fractures of the neck of femur especially in patients with poor premorbid conditions, minimally displaced fractures and those from a younger age group. A five year retrospective study was carried out in 53 consecutive patients between 2006 to 2010 to determine the pattern of injuries, management, outcomes and the associated predictive factors.All the patients underwent cannulated screw fixation, with 37 (69.8% having had surgery within 24 hours and the remaining 16 (30.2% 24 hours after the initial injury. All patients were followed up to union of fractures and complications thereafter if any. Good outcome was observed in 43 (81.1% patients leaving only 10 (18.9% patients with a poor outcome, of whom nine developed avascular necrosis (90% and one non-union (10%. We found no significant relationship between the incidence of avascular necrosis and age of patient, fracture displacement, numbers of cannulated screws used, fracture reduction acceptability and anatomical location of the fracture. The time interval from injury to surgery and the presence of posterior comminution did seem to influence the rate of avascular necrosis but due to the small number of patients, was not statistically significant.We conclude that cannulated screw fixation is a viable option of treatment for fractures of the neck of femur.

    Background: Stress fractures of the naviculum bone are uncommon injuries occurring predominantly in athletes. These fractures are usually treated nonoperatively with a nonweight bearing cast for a minimum of 6 weeks followed by rehabilitation. Further, there is a paucity of literature on the long term clinical followup of these patients. These fractures do not heal predictably with conservative management, which does not inspire great compliance and their clinical outcome is variable. We repo...

  17. REVERSE ENGINEERING OF THE MITKOVIC TYPE INTERNAL FIXATOR FOR LATERAL TIBIAL PLATEAU

    Directory of Open Access Journals (Sweden)

    Nikola Vitković

    2015-12-01

    Full Text Available In orthopaedic surgery it is very important to use proper fixation techniques in the treatment of various medical conditions, i.e. bone fractures or other traumas. If an internal fixation method, such as plating, is required, it is possible to use Dynamic Compression Plates (DCP or Locking Compression Plates (LCP and their variants. For DCP implants it is important to match the patient's bone shape with the most possible accuracy, so that the most frequent implant bending is applied in the surgery. For LCP implants it is not so important to match the patient’s bone shape, but additional locking screw holes are required. To improve the geometrical accuracy and anatomical correctness of the shape of DCP and to improve the LCP geometric definition, new geometrical modelling methods for the Mitkovic type internal fixator for Lateral Tibia Plateau are developed and presented in this research. The presented results are quite promising; it can be concluded that these methods can be applied to the creation of geometrical models of internal fixator customized for the given patient or optimized for a group of patients with required geometrical accuracy and morphological correctness.

  18. Bicondylar tibial plateau fracture treated by open reduction and fixation with unilateral locked plating

    2013-10-01

    Full Text Available The management of bicondylar tibial plateau fractures is challenging. A lateral locking plate offers an alternative method to traditional dual plating to avoid further stripping of soft tissue. Nevertheless, the rate of malreduction and fixation loss remains high. From 2007 to 2009, we performed open reduction and fixation with unilateral locked plating to directly reduce the fracture in 15 patients with bicondylar plateau fracture. The average follow-up duration was 16.2 months (range: 12–30 months, and the average age of the patients was 43 years (range: 19–64 years. All fractures were Orthopaedic Trauma Association type 41-C. Postoperative radiographic alignment was evaluated immediately and at 2–4 weeks, 8–12 weeks, 5–7 months, and 11–13 months. Both Oxford knee score and Hospital for Special Surgery knee score were used to evaluate functional outcomes. The average duration within which union was achieved was 4.8 months (range: 2–10 months. One patient incurred wound dehiscence; however, there was no case of deep infection. Malreduction occurred in one patient (6.7% while fixation loss occurred in three patients (20% with subsidence of the posteromedial fragment and varus malalignment. Despite the malreduction rate being lower in our study than in previous studies involving unilateral locked plating, a high rate of fixation loss was recorded. Per our limited experience, we believe that unilateral locked plating may have limitations in patients with selective patterns of bicondylar tibial plateau fractures.

    This study aimed to evaluate the outcome of using a metaphyseal locking plate as a definitive external fixator for treating open tibial fractures based on biomechanical experiments and analysis of clinical results. A metaphyseal locking plate was used as an external fixator in 54 open tibial fractures in 52 patients. The mean follow-up was 38 months (range, 20-52 months). Moreover, static axial compression and torsional tests were performed to evaluate the strength of the fixation techniques. The average fracture healing time was 34.5 weeks (range, 12-78 weeks). At 4 weeks postoperatively and at the final follow-up, the average Hospital for Special Surgery knee score was 85 (range, 81-100) and 94 (range, 88-100), respectively, and the American Orthopaedic Foot and Ankle Society score was 88 (range, 80-100) and 96 (range, 90-100), respectively. Based on the static test result, the axial stiffness was significantly different among groups (p=0.002), whereas the torsional stiffness showed no significant difference (p=0.068). Clinical outcomes show that the use of locking plate as a definitive external fixator is an alternative choice for tibial fractures after obtaining appropriate fracture reduction. However, external locked plating constructs were not as strong as standard locked plating constructs. Therefore, the use of external locked plating constructs as a definitive treatment warrants further biomechanical study for construct strength improvement. Copyright © 2016 Elsevier Ltd.

    2012-08-01

    Osteochondral fracture of the patella following a lateral patellar dislocation can be treated with operative and nonoperative techniques that are dictated by the clinical presentation. In the presence of large fragments following acute fractures, arthroscopic retrieval and fixation are advocated, whereas smaller displaced fragments may be removed and discarded as loose bodies. Several methods of fixation exist for osteochondral fractures of the patella, including the use of cannulated and noncannulated screws.This article describes a case of an elite competitive swimmer who sustained a lateral patellar dislocation with a large osteochondral fracture of the patella that was treated with open reduction and fixation using absorbable cannulated screws in an inside-out fashion. In the early postoperative period, the patient developed a symptomatic synovial fluid fistula through a cannulated screw to the prepatellar space. The diagnosis of this condition was made clinically and confirmed with noncontrast magnetic resonance imaging 6 weeks postoperatively. The symptoms of pain, skin erythema, and swelling were self-limited and eventually resolved with observation, allowing the athlete to return to his previous activity level. Magnetic resonance imaging 3 years postoperatively showed the complete resolution of the fluid extravasation. Extra-articular synovial fluid extravasation is as a rare complication following routine knee arthroscopy, accounting for 3.2% of the complications. This article describes a rare, self-limited complication following open fixation of an osteochondral fracture of the patella. Copyright 2012, SLACK Incorporated.

    1979-09-01

    One hundred consecutive patients with displaced fractures of the tibial shaft were randomly assigned to two groups, one treated with AO-plate fixation and the other with conservative methods. Strictly conservative treatment failed in two patients because of the interposition of muscles. Comparison of the groups showed that a longer duration of hospital stay was needed in the AO-plate group, and there were also more complications in that group. However, the median healing time was shorter and the anatomical end results were better than in the conservatively treated patients. Closed longitudinal fractures were found to be suitable and open fractures, unsuitable for AO-plate fixation. In the group that was treated conservatively most fractures that healed in malalignment were located in the distal third of the tibial shaft.

    This biomechanical study compared the stability of four different ramus fracture fixation methods for Type C pelvic ring injuries in the absence of posterior fixation. A 5-mm vertical osteotomy of the mid-superior and inferior pubic ramus was created in 12 synthetic pelvic models. Four surgical constructs were compared: (1) two-pin AIIS external fixation, (2) 3.5-mm reconstruction plating, (3) bicortical, fully threaded 3.5-mm, and (4) 6.5-mm pubic ramus screws. Specimens were tested in a simulated one-legged stance on a hemiarthroplasty implant in three stages: (1) no applied load, (2) application of the loading fixture preload to the sacrum (6N), and (3) following six cycles of a 250N load. Stability was assessed based on resultant displacement of the fracture sites at the superior ramus and the anterior sacroiliac joint. The bicortical, fully threaded 6.5-mm pubic ramus screw provided the most stable ramus fracture fixation (0.5 ± 0.4 mm) displacement under load and was the only construct to finish testing without gross posterior pelvic disruption. Plate constructs finished the final loading stage with only a small increase (3.1 ± 2.3 mm) in ramus fracture gap size, but had significant displacement at the SI joint (>20 mm). 3.5-mm screw constructs had 1.6 ± 0.7 mm of ramus displacement in the preload stage, but had complete posterior pelvic disruption (>20 mm) that prevented further testing. External fixation was unstable at the ramus and sacroiliac sites in the initial setup. The bicortical, fully threaded 6.5-mm pubic ramus screw was the only anterior fixation construct tested that controlled motion at both the anterior and posterior pelvic rings in the absence of posterior fixation.

    Orthopedic and hand surgery implants for internal fixation of fractures have evolved substantially over the past 50 years. Newer metal compositions have been used, and new standards have been applied to older alloys, resulting in modern implants with unique physical properties and better clinical performances. Conventional wisdom has long dictated that implanting different metals should be avoided, but few guidelines exist regarding the safety of using in proximity implant systems of dissimilar metals. To better characterize the landscape of internal fixation implant metallurgy, we have compiled the recommendations and conclusions of the currently available and pertinent literature.

    2018-03-13

    An important consideration when counselling patients with midshaft clavicle fractures is whether operative treatment of non-union, if it develops after non-operative treatment, is associated with higher complication rate than acute fracture fixation. The aim of this study is to compare complications and re-operations after open reduction and plate fixation for acute midshaft clavicle fractures versus non-unions. The study was retrospective. There were 90 patients in the acute fixation group and 20 patients in the non-union group. The mean follow-up was 8 and 15 months, respectively, Logistic regression analysis was used to assess whether 'non-union surgery' was a predictor of complications and re-operations. Of 90 patients, 23 had complications in acute fixation group. Of 20, 7 developed 8 complications in the non-union group (p = 0.4). Of 90, 12 required re-operations in the acute fixation group compared to 5/20 requiring 7 re-operations in the non-union group (p = 0.19). When any complication or re-operation was considered, 'non-union surgery' was not significant predictor for complications (p = 0.78) or re-operations (p = 0.99). The complication and re-operation rates were not higher after non-union surgery compared to acute fracture fixation and were mostly related to persistent delayed or non-union, rather than operative complications. When counselling patients about treatment of midshaft clavicle fractures, a 'higher complication rate after surgery for non-union, should it happen' should not be an argument against non-operative treatment.

    1996-01-01

    Shaft fractures of the femur or tibia or both are frequent components of multiple trauma. Besides the local fracture impact, they induce considerable systemic distress to remote organs because of pain, blood loss, necrotic or hypoperfused tissues, and mediator release. Additionally, unstable...... skeletal conditions (particularly of the lower extremities) impede optimal intensive care of these patients. Therefore in a polytrauma setup, primary operative stabilization of the femur is mandatory and generally accepted, whereas the optimal fixation procedure is still a source of controversies...

    Comminuted and displaced fractures of the inferior pole of the patella are not easy to reduce and it is difficult to fix the fragments soundly enough to allow early movement of the knee. The purpose of this study is to evaluate the clinical effectiveness of the internal fixation technique with Patellar Shape-Memory Fixator (PSMF) in acute comminuted fractures of the inferior pole of the patella. We retrospectively studied 25 patients with comminuted fractures of the inferior pole of the patella who were treated with PSMF and followed up for a mean period of 26 months (14 to 60). All the fractures healed at a mean of 6 weeks (5 to 7). The mean grading at the final follow-up was 29.5 points (27 to 30) using the Bostman score, with no observable restriction of movement. No breakage of the PSMF or infection occurred. No delayed union, nonunion, and infection were seen. This technique preserved the length of the patella, reduced the comminuted fragments of the inferior pole and avoided long-term immobilization of the knee.

    and B were better than that of group C. In group C, 2 patients had incision infections, 6 patients complained of foreign body sensation, 1 patient got a delayed fracture healing, and 1 patient had the heterotopic ossification. There were no occurrences of incision infections in group A and B; internal fixation loosening occurred in 3 patients in group A and 2 patients in group B; delayed fracture healing occurred in 2 patients in group A and 2 patients in group B; and skin bursa formation occurred in 6 patients in group A and 1 patient in group B. All the three ways are effective methods for the treatment of olecranon fractures. Fixation methods should be selected depending on the type of fracture.

    Full Text Available A fratura Salter Harris tipo II ocorre comumente na epífise proximal de tíbia em potros e tem reparação difícil mas com o advento das técnicas de fixação interna, o prognóstico tem melhorado. No caso descrito, em um potro da raça árabe de 26 dias de idade, com fratura proximal de tíbia direita tipo Salter Harris II, foram utilizadas as placas de compressão para garantirem estabilização e aproximação dos fragmentos fraturados, porém com risco de ocasionar distúrbios no desenvolvimento esquelético. No caso relatado, através do controle radiológico, não foi evidenciada diminuição da radioluscência na região correspondente à cartilagem de conjugação proximal da tíbia. O artigo tem como objetivo discutir o tratamento empregado que se mostrou como alternativa viável pelo resultado favorável com bons resultados.The most frequent fracture is tibia’s proximal epiphysis in foals is Salter Harris type II although its difficult to repair. The development of the inner fixation technique has been made the prognosis better. The dynamic compression bone plate allow guaranteed reduction and stabilization of the bone’s fragments, but it can promote development disturbs. In this case, by the radiological control, it has not shown less radiolucency in the proximal tibia’s growth plate. The treatment used showed itself as a feasible alternative because of the favourable good results.

    This paper was aimed at evaluating two changes in the external fixators for osteosynthesis of the humeral fracture that induce the correction of the humeral fracture in pigeons. The reduction of diaphyseal fracture was made with an intramedulary pin associated to another perpendicular one inserted into the distal segment (Group A - GA); in the Group B (GB) an additional pin was used in the proximal fragment. All the pigeons were evaluated clinically and radiographically up to 60 days, except for four of each group which were submitted to euthanasia at 15, 22, 29 and 36 days for the macro and microscope exams. The flight test was successful in all pigeons. The bone calus was radiografically visible only in the GA; the mean time and the standard deviation for flight was 32.25 ± 6.5 days for the GA and 39.8 ± 3.83 for the GB. The mean time and standard deviation for fracture healing was 36 ± 0 days in the GA and 34 ± 3.4 in the GB. The two types of external fixator evaluated were efficient to stabilized the fracture site allowing complete consolidation and return to function. The use of the external fixator with two perpendicular pins provides more stability at the fracture site although it is necessary more time for the surgery procedure [pt

    The effectiveness and best method to manage dorsal cortical stress fractures is not clear. This study was performed to evaluate the success of lag screw fixation of such fractures in a population of Thoroughbred racehorses. Lag screw fixation of dorsal cortical stress fractures is an effective surgical procedure allowing racehorses to return to their preoperative level of performance. The records of 116 racehorses (103 Thoroughbreds) admitted to Equine Medical Centre, California between 1986 and 2008 were assessed. Information obtained from medical records included subject details, limb(s) affected, fracture configuration, length of screw used in repair and presence of concurrent surgical procedures performed. Racing performance was evaluated relative to these factors using Fisher's exact test and nonparametric methods with a level of significance of Phorses, 83% raced preoperatively and 83% raced post operatively, with 63% having ≥5 starts. There was no statistically significant association between age, gender, limb affected, fracture configuration or presence of concurrent surgery and likelihood of racing post operatively or of having 5 or more starts. The mean earnings per start and the performance index for the 3 races following surgery were lower compared to the 3 races prior to surgery; however, 29 and 45% of horses either improved or did not change their earnings per start and performance index, respectively. Data show that lag screw fixation is successful at restoring ability to race in horses suffering from dorsal cortical stress fractures. © 2010 EVJ Ltd.

    Full Text Available Background : A short vertebral arthrodesis has been one of the objectives of the surgical treatment of fractures of the thoracolumbar spine. We present here clinical, functional and radiographic outcome obtained after monosegmental fixation (single posterior or combined anterior and posterior of specific types of unstable thoracolumbar fractures. Materials and Methods : Twenty four patients with fractures of the thoracolumbar spine submitted to monosegmental surgical treatment (Group I - 18 single posterior monosegmental fixations and Group II - 6 combined anterior and posterior fixations were retrospectively evaluated according to clinical, radiographic and functional parameters. The indication for surgery was instability or neurological deficit. All the procedures were indicated and performed by the senior surgeon (Helton LA Defino. Results : The patients from group I were followed-up from 2 to 12 years (mean: 6.65±2.96. The clinical, functional and radiographic results show that a single posterior monosegmental fixation is adequate and a satisfactory procedure to be used in specific types of thoracolumbar spine fractures, The patients from group II were followed-up from 9 to 15 years (mean: 13 ± 2,09 years. On group II the results of clinical evaluation showed moderate indices of residual pain and of satisfaction with the final result. The values obtained by functional evaluation showed that 66.6% of the patients were unable to return to their previous job and presented a moderate disability index (Oswestry = 16.6 and a significant reduction of quality of life based on the SF-36 questionnaire. Radiographic evaluation showed increased kyphosis of the fixed vertebral segment during the late postoperative period, accompanied by a reduction of the height of the intervertebral disk. Conclusion : It is possible to stabilize the fractures which have an anterior good load-bearing capacity by a standalone posterior monosegmental fixation. However

    Mono-segment transpedicular fixation is a method for the treatment of certain types of thoracolumbar spinal fracture. Finite element models were constructed to evaluate the biomechanics of mono-segment transpedicular fixation of thoracolumbar fracture. Spinal motion (T10-L2) was scanned and used to establish the models. The superior half of the cortical bone of T12 was removed and the superior half of the cancellous bone of the T12 body was assigned the material properties of injured bone to mimic vertebral fracture. Transpedicular fixation of T11 and T12 was performed to produce a mono-segment fixation model; T11 and L1 were fixed to produce a short-segment fixation model. Motion differences between functional units and von Mises stress on the spine and implants were measured under axial compression, anterior bending, extensional bending, lateral bending and axial rotation. We found no significant difference between mono- and short-segment fixations in the motion of any functional unit. Stress on the T10/T11 nucleus pulposus and T10/T11 and L1/L2 annulus fibrosus increased significantly by about 75% on anterior bending, extensional bending and lateral bending. In the fracture model, stress was increased by 24% at the inferior endplate of T10 and by 43% at the superior endplate of L2. All increased stresses were reduced after fixation and lower stress was observed with mono-segment fixation. In summary, the biomechanics of mono-segment pedicle screw instrumentation was similar to that of conventional short-segment fixation. As a minimally invasive treatment, mono-segment fixation would be appropriate for the treatment of selected thoracolumbar spinal fractures. © IMechE 2014.

    To determine the effect of interfragmentary appositional (gap-closing) screw fixation in minimally invasive plate osteosynthesis (MIPO) for distal tibial fractures on the clinical and radiologic results. Prospective nonrandomized study. Level I trauma center. Sixty patients who were diagnosed as distal metadiaphyseal oblique or spiral tibial fracture without displaced articular fragment. Thirty patients (group A) of the 60 patients were treated with MIPO without appositional screw fixation, and the other 30 (group B) were treated with the screw. Radiologic union, clinical union, clinical functional score [American Orthopaedic Foot and Ankle Society (AOFAS) score], and complications. The time for initial callus formation and radiologic union was significantly longer in group A than those in group B (76.8 vs. 58.0 days, P = 0.044; 409 vs. 258.7 days, P = 0.002, respectively). The rate of clinical union during 1 year was significantly higher in group B than in group A (P = 0.0063). Four nonunion patients in group A achieved bone union after placement of an additional bone graft. None of the patients in group B diagnosed with delayed union or nonunion (P screw fixation in distal tibia MIPO for the fixation of oblique or spiral fracture promoted callus formation and union rate compared with MIPO without appositional screw fixation.

    To evaluate the efficacy of intramedullary nailing of distal tibia fractures using modern techniques, without fibula fixation, in obtaining and maintaining alignment. Retrospective case review. Level-I academic trauma center. One hundred thirty-two consecutive patients with distal tibia fractures. Intramedullary nail of distal tibia fracture, without fibula fixation, was performed in consecutive patients using modern reduction techniques. Malalignment and malunion were defined as >5 degrees of varus/valgus angulation or anterior/posterior angulation on the initial postoperative or final anteroposterior and lateral x-rays. There were 122 consecutive patients (86 men and 36 women) 16-93 years of age (average, 43 years) with 36 (30%) open and 85 (70%) closed fractures with complete follow-up. Mechanism of injury did not predict the presence or level of fibula fracture. Upon presentation, varus/valgus and procurvatum/recurvatum angulation was greatest when the fibula was fractured at the level of the tibia fracture (P = 0.001 and 0.028). The most common intraoperative reduction aids were nailing in relative extension, transfixion external fixation, and clamps at the fracture site. The OTA fracture type or level/presence of fibula fracture did not influence malalignment (P = 0.86 and 0.66), malunion (P = 0.81 and 0.79), or the change in alignment during union, which averaged 0.9 degrees. We found an overall low rate of both malalignment (2%) and malunion (3%) after intramedullary nailing of distal tibial shaft fracture without fibula fixation. We conclude that when modern nailing techniques are used, which allow for confirmation of reduction by visualization in fluoroscopy, from nail placement to distal interlocking, fibula fixation is not necessary to obtain or maintain alignment. Furthermore, standard 2 medial to lateral screws distally afford adequate stability to hold the reduction during union with a 0.9-degree difference in the initial postoperative and final

    Full Text Available Abstract Calcaneal fractures are common injuries involving the hind foot and often a source of significant long-term morbidity. Treatment options have changed throughout the ages from periods of preferred nonoperative management to closed reduction with a mallet, and more recently, open reduction and anatomic internal fixation. The current treatment of choice; however, is often debated, as open management of these fractures carries many risks to include wound breakdown and infection. A less invasive form of surgical management through small incisions, while maintaining the ability to obtain joint congruency, anatomic alignment, and restore calcaneal height and width would be ideal. We propose a novel form of fracture reduction using an inflatable bone tamp and percutaneous fracture fixation. Preoperative planning and experienced fluoroscopy is crucial to successful management using this method. Although we achieved successful radiographic outcome in this case, long-term functional outcome of this technique are yet to be published.

    Full Text Available Fractures of neck of femur have always presented great challenges to the orthopaedic surgeons. This remains, even today, an unsolved fracture as far as treatment and results are concerned. Results depend upon the extent of injury, timing of surgery and adequacy of reduction and fixation. Fixation with cannulated cancellous screws is usually adequate for femoral neck fractures. Lateral cortex plays a very important role in screw fixation. AIMS AND OBJECTIVES To study the effectiveness of cannulated cancellous screw fixation for treatment of fracture of neck of femur in adults. MATERIALS AND METHODS This study was conducted at Andhra Medical College, King George Hospital, Visakhapatnam, AP from Nov 2013 to Oct 2015. The patients with intracapsular fracture of neck of femur are evaluated with pre-operative X-rays of pelvis with both hips and X-ray of the concerned hip joint both in anteroposterior and lateral views and their outcome was evaluated postoperatively after fixation with cancellous screws. The outcome is evaluated in terms of pain relief, extent of ambulation achieved after surgery. The classifications we followed are Pauwel’s and Garden’s classification of fracture of neck of femur. The patients were followed up to one year to assess the functional outcome. OBSERVATION AND RESULTS A good result was obtained in 66.1% of the patients, excellent in 23.2%, fair in 3.8% and poor result in 6.9% of the patients. Complications such as Non-union & avascular necrosis in one case, Non-union and Extrusion of screws in one case, Cut through of screws into articular surface leading to painful joint in one case. Most of the cases of intracapsular neck of femur were in the age group of 31-40 years. There was male preponderance as shown in this study (69%. CONCLUSION By the usage of multiple cannulated cancellous lag screws, compression effect at the fracture site is achieved, it also avoids re-displacement and rotations. The implant occupies less

    Background Intermaxillary fixation is used to achieve proper occlusion during and after oral and maxillofacial fracture surgery. The aim of this systematic review was to compare Erich arch bar fixation with other intermaxillary fixation methods in terms of the operating time, safety during installation, oral health maintenance and occlusal stability. Material and Methods An electronic online search was conducted of the Scirus, PubMed, Ovid, Cochrane Library and VHL databases. A clinical trial dating from the inception of the data bases until August 2013 was selected. Studies that compared Erich arch bars with other intermaxillary fixation methods in patients older than 18 years-old were included. The studies were assessed by two independent reviewers. The methodological quality of each article was analyzed. Results Nine hundred and twenty-five manuscripts were found. Seven relevant articles were analyzed in this review. The risk of bias was considered moderate for four studies and high for three clinical trials. Conclusions There is not enough evidence to conclude that the Erich arch bar is the best intermaxillary fixation method in cases of oral and maxillofacial fractures. Key words: Facial injuries, jaw fixation techniques, mandible, maxilla. PMID:26034929

    Transepiphyseal screw fixation of displaced distal tibial epiphyseal fractures is the most common method of treatment for these intraarticular injuries. Recent literature indicates that retained transepiphyseal metallic screws cause an increase in ankle joint contact pressure, thus favoring screw removal. Our hypothesis is that bioabsorbable screw fixation is an alternative to metallic fixation, which offers similar results without the need for screw removal. This is a retrospective review of distal tibial epiphyseal ankle fractures treated with screw fixation. Two groups, those treated with bioabsorbable screw fixation (group B, n = 24) and those with metallic screw fixation (group M, n = 26), were compared (t test) for differences in clinical and radiographic outcomes. Analysis of demographic data revealed no significant differences between groups for sex, ethnicity, age, and height. Group B was significantly heavier than group M (67.4 vs 55.6 kg; P = 0.0496). Each group had a similar number of Salter-Harris types III and IV medial malleolus fractures and transitional fracture types. There was no significant difference between groups in the time from injury to fixation or in operative time. Radiographically, there were no nonunions in either group, and at final follow-up, 1 patient in group B had distal tibial joint line irregularity versus 3 in group M. Clinically, there were no significant differences between groups in time to full weight bearing or time to full activities.There were fewer complications in group B. A single case of loss of reduction requiring revision fixation occurred in each group. There was one documented growth arrest in group M and 2 suspected growth arrests in each group. Two patients in group M were successfully treated for a superficial wound infection with oral antibiotics. Fourteen patients in group M underwent planned screw removal. Bioabsorbable screw fixation can be used for distal tibial epiphyseal fractures with no increase in

    To study the angle of screw placement in relation to the scaphoid fracture plane and its effect on union after percutaneous fixation of scaphoid waist fractures. Twenty-four consecutive scaphoid waist fractures were retrospectively evaluated for the orientation of screws in relation to the fracture plane using a method in which the sum-of-smaller angles (SSA) in 3 different radiographs were used to correlate with time to fracture union. All but one patient achieved union after percutaneous fixation of the scaphoid. Another patient required revision surgery within the study period for inadequate fixation. A shortened time to union was significantly correlated to larger SSA. SSA may be a reasonable predictor of union after percutaneous fixation of scaphoid waist fracture. It can be reliably calculated using plain radiographs. An SSA of 190° or more correlated with union by 8 weeks postoperatively. Copyright © 2016 American Society for Surgery of the Hand.

    Full Text Available INTRODUCTION: Coaptive film (i.e., Steri-StripsTM is an adhesive tape used to replace sutures in wound closure. The use of coaptive film for wound closure after long bone fracture fixation has not been well documented in the literature. METHODS: The aim of this prospective, randomized controlled trial comparing coaptive film with sutures for wound closure after long bone fracture fixation was skin closure time, incidence of wound complications and scar width at 12 week follow-up. Forty-five patients underwent femur fracture fixation (22 patients’ wound closed with sutures, 23 with coaptive film. RESULTS: The mean time for skin closure using coaptive film was 171.13 seconds compared to 437.27 seconds using suture. The mean wound lengths in the coaptive film group and suture group were 187.65 mm and 196.73 mm, respectively. One patient in each group had wound complications. CONCLUSION: Coaptive film is a time-saving procedure for skin closure following long bone fracture fixation. There is no difference in the incidence of wound complications and scar width between these two methods of skin closure.

  6. FUNCTIONAL OUTCOME OF INTERTROCHANTERIC FRACTURES AFTER FIXATION WITH PFN OR DHS IN ELDERLY- A COMPARATIVE STUDY

    Full Text Available BACKGROUND Ninety percent of the hip fractures in the elderly result from a simple fall. More than fifty percent of the hip fractures in the elderly are intertrochanteric fractures. The goal of treatment of any intertrochanteric fracture in elderly is to restore mobility at the earliest and minimise the complications of prolonged bed rest. The Dynamic Hip Screw (DHS has been shown to produce good results, but complications are frequent, particularly in unstable intertrochanteric fractures. Intramedullary fixation is considered to provide a more biomechanically stable construct by reducing the distance between the hip joint and implant. MATERIALS AND METHODS The goal of this study is to compare the functional outcome of intertrochanteric fractures in elderly patients treated with Proximal Femoral Nail (PFN and Dynamic Hip Screw (DHS by analysing the clinical and radiological results to evaluate the advantages and disadvantages and possible complications associated with fixation of intertrochanteric fractures with PFN and DHS. 1 In our study, we included 106 intertrochanteric fractures, out of which 46 were treated with PFN and 60 with DHS. Ordinary fracture table was used in all cases and were followed up at regular intervals of 4, 8 and 12 weeks, 6 months and one year. RESULTS Functional results were assessed with modified Harris hip score. We observed significantly higher excellent results and less poor results in PFN compared to DHS. CONCLUSION Unstable intertrochanteric fractures treated with PFN have significantly better outcome than DHS. In unstable fractures, reduction loss, union in varus and limb shortening are significantly higher in DHS. Hence, the advantages of PFN are less surgical trauma, less blood loss and the possibility of early weightbearing even after very complex fractures.

    Placement of sacral fixation screws at surgery is performed blindly (ie, by palpation). The authors of this paper employed CT to localize the screw between the neutral foramina and anterior sacral cortex and to decrease the morbidity associated with general anesthesia and surgery. Six patients underwent CT-guided sacral fixation performed by means of the 7.0 mm A0 cannulated screw system. All patients had reducible vertical sacral fractures or sacroiliac joint disruptions. Following placement of an epidural catheter for anesthesia, patients were scanned in the prone or decubitus position. Measurements for placement of the guide pin were made from the preliminary scans. Following CT confirmation of satisfactory guide pin placement across the fracture, the screw track was drilled, the screw length was determined, and the fixation screw was placed in position. A CT scan was obtained to evaluate the final position of the screw

    Osteosynthesis and reposition of the Charcot foot is challenging with respect to choice of a proper implant. There is currently no international consensus regarding the optimal implant. Locking plates seem to be an innovative and stable method for reconstruction. The aim of this work is to analyze bone fusion, complications, pseudoarthrosis, and patient satisfaction. This paper presents a retrospective analysis of 63 consecutive Charcot feet treated between 2004 and 2014. The mean follow-up time was 2.4 years. All Charcot feet treated between 2004 and 2014 were Sanders type II or III. A bony fusion was achieved in 50 % of the cases, 26 % had a functional pseudoarthrosis with intact implants and pain-free mobility, and 22 % showed no healing with broken implants. Conclusion Internal fixation with locking plates is superior to screw fixation only with regard to biomechanics. We prefer internal fixation plates to external fixation because of stability even in the case of pseudoathrosis and because of the learning curve.

    Humero-ulnar external fixation has been proposed to treat complex supracondylar humeral fractures in children. It facilitates fracture reduction and reduces the risk of ulnar nerve lesion, which can occur after cross pinning. In a ten year period, 28 children have been operated on in our centre by humero-ulnar external fixation, for Lagrange-Rigault stages III and IV supracondylar humeral fractures. The data about fracture management and early follow-up were obtained from our medical database. The long-term evaluation was done at a minimum six months' follow-up. The range of motion and carrying angle measurements were classified according to Flynn. The final X-rays were evaluated for quality of reduction, presence of malunion, late infection signs, osteo-arthritis and myositis ossificans. The elbow function was evaluated by Mayo Elbow Performance Index (MEPI), Disabilities of the Arm, Shoulder and Hand (DASH) or modified DASH scores. The treatment was well tolerated by children and parents. There was no neurological complication related to the insertion of the pins, and no Volkmann syndrome. The median duration of external fixation was 33.5 days. Twelve patients were reviewed after a median follow-up duration of seven years (mean, 7.5 years; range, 3-21 years). One child had a refracture, three years after his original fracture, which was treated non-operatively. This case ended up in a cubitus varus deformity with a pronation deficit. All other patients had excellent clinical and radiological results. For the treatment of complex supracondylar humeral fractures in children, humero-ulnar external fixation is a good alternative to lateral or crossed pinning. The advantages are the ease to obtain the reduction, the absence of neurological risk to the ulnar nerve and the possibility to obtain good stabilisation of the fracture with moderate elbow flexion.

    Posterior wall fractures are one of the most common acetabular fractures. However, only 30% of these fractures involve a single large fragment, and comminuted acetabular posterior wall fractures pose a particular surgical challenge. The purpose of this study was to compare outcomes between patients who received fixation for comminuted posterior wall fracture using the Acetabular Tridimensional Memory Fixation System (ATMFS) and patients who underwent fixation with conventional screws and buttress plates (Plates group). Between April 2003 and May 2007, 196 consecutive patients who sustained a comminuted posterior wall fracture of acetabulum were treated with ATMFS or conventional screws and buttress plates. Operative time, fluoroscopy time, blood loss, and any intra-operative complications were recorded. Plain AP and lateral radiographs were obtained at all visits (Matta's criteria). Modified Merle d' Aubigne-Postel score, and Mos SF-36 score were compared between groups. Fifty patients were included in the analysis with 26 in the ATMFS group and 24 in the Plates group. The mean follow-up time was 57.5 months, ranging from 31 to 69 months. All patients had fully healed fractures at the final follow-up. There was no difference in clinical outcomes or radiological evaluations between groups. Patients with comminuted posterior wall fractures of the acetabulum treated with the ATMFS or conventional screws and buttress plate techniques achieve a good surgical result. Both techniques are safe, reliable, and practical. Use of the ATMFS technique may reduce blood loss and improve rigid support to marginal bone impaction. The use ATMFS may need additional support when fractures involve the superior roof. Copyright © 2013 Elsevier Ltd. All rights reserved.

    To highlight a technique combining fluoroscopy and arthroscopy to aid percutaneous reduction and internal fixation of selected displaced intra-articular calcaneal fractures, assess outcome scores, and compare this method with other previously reported percutaneous methods. Retrospective review of all patients treated by this technique between June 2009 and June 2012. A tertiary care center located in Brisbane, Queensland, Australia. Thirteen consecutive patients were treated by this method during this period. All patients had a minimum of 13 months follow-up and were available for radiological checks and assessment of complications; functional outcome scores were available for 9 patients. The patient was placed in a lateral decubitus position. Reduction was achieved with the aid of both intraoperative fluoroscopy and subtalar arthroscopy and held with cannulated screws in orthogonal planes. The patient was mobilized non-weight bearing for 10 weeks. Outcomes measured were improvement in Bohler angle, postoperative complications, and 3 functional outcome scores (American Orthopaedic Foot and Ankle Society ankle-hindfoot score, Foot Function Index, and Calcaneal Fracture Scoring System). Mean postoperative improvement in Bohler angle was 18.3 degrees, with subsidence of 1.7 degrees. Functional outcome scores compared favorably with the prior literature. Based on available postoperative computed tomography scans (8/13), maximal residual articular incongruity measured 2 mm or less in 87.5% of our cases. Early results indicate that this technique, when combined with careful patient selection, offers a valid therapeutic option for the treatment of a distinct subset of displaced intra-articular calcaneal fractures, with diminished risk of wound complications. Large, prospective multicenter studies will be necessary to better evaluate the potential benefits of this technique. Level IV Therapeutic.

    Full Text Available Introduction: Free grafting or extracorporeal fixation of traumatically displaced mandibular condyles is sometimes required in patients with severe anteromedial displacement of condylar head. Majority of the published studies report the use of a submandibular, retromandibular or preauricular incisions for the access which have demerits of limited visibility, access and potential to cause damage to facial nerve and other parotid gland related complications. Purpose: This retrospective clinical case record study was done to evaluate the preauricular transmasseteric anteroparotid (P-TMAP approach for open reduction and extracorporeal fixation of displaced and dislocated high condylar fractures of the mandible. Patients and Methods: This retrospective study involved search of clinical case records of seven patients with displaced and dislocated high condylar fractures treated by open reduction and extracorporeal fixation over a 3-year period. The parameters assessed were as follows: a the ease of access for retrieval, reimplantation and fixation of the proximal segment; b the postoperative approach related complications; c the adequacy of anatomical reduction and stability of fixation; d the occlusal changes; and the e TMJ function and radiological changes. Results: Accessibility and visibility were good. Accurate anatomical reduction and fixation were achieved in all the patients. The recorded complications were minimal and transient. Facial nerve (buccal branch palsy was noted in one patient with spontaneous resolution within 3 months. No cases of sialocele or Frey's syndrome were seen. Conclusion: The P-TMAP approach provides good access for open reduction and extracorporeal fixation of severely displaced condylar fractures. It facilitates retrieval, transplantation, repositioning, fixing the condyle and also reduces the chances of requirement of a vertical ramus osteotomy. It gives straight-line access to condylar head and ramus thereby

    Traditional fixation of unstable Orthopaedic Trauma Association type B/C ankle fractures consists of a lag screw and a lateral or posterolateral neutralization plate. Several studies have demonstrated the clinical success of lag screw only fixation; however, to date no biomechanical comparison of the different constructs has been performed. The purpose of the present study was to evaluate the biomechanical strength of these different constructs. Osteotomies were created in 40 Sawbones(®) distal fibulas and reduced using 1 bicortical 3.5-mm stainless steel lag screw, 2 bicortical 3.5-mm lag screws, 3 bicortical 3.5-mm lag screws, or a single 3.5-mm lag screw coupled with a stainless steel neutralization plate with 3 proximal cortical and 3 distal cancellous screws. The constructs were tested to determine the stiffness in lateral bending and rotation and failure torque. No significant differences in lateral bending or rotational stiffness were detected between the osteotomies fixed with 3 lag screws and a plate. Constructs fixed with 1 lag screw were weaker for both lateral bending and rotational stiffness. Osteotomies fixed with 2 lag screws were weaker in lateral bending only. No significant differences were found in the failure torque. Compared with lag screw only fixation, plate fixation requires larger incisions and increased costs and is more likely to require follow-up surgery. Despite the published clinical success of treating simple Orthopaedic Trauma Association B/C fractures with lag screw only fixation, many surgeons still have concerns about stability. For noncomminuted, long oblique distal fibula fractures, lag screw only fixation techniques offer construct stiffness similar to that of traditional plate and lag screw fixation.

    Full Text Available Background In surgical treatment of thoracolumbar burst fractures, most authors try to lower the number of vertebrae involved during the surgery. Objectives The aim of this study was to evaluate the outcome of a medium-segment posterior spinal fixation in these patients. Patients and Methods We retrospectively reviewed 27 patients (18 male, 9 female with mean age of 39.4 ± 15.0 years old in a before-and-after study. The mean follow-up period was 38.4 ± 15.6 months. We involved 2 intact above vertebrae and one intact below vertebra, inserting a pedicular screw at the fractured level and supplemented the construct with contralateral infralaminar hook. Clinical and radiologic characteristics were assessed with American spinal injury association (ASIA scale, oswestry disability index (ODI, visual analogue scale (VAS, and plain radiography. Data analysis was carried out by SPSS version 11.5 software. Results Mean post traumatic kyphosis was + 15.7° ± 3.3° that was changed to - 8.5° ± 4.3° and +1° ± 4.4° at immediate and last visit after surgery, respectively. Mean loss of correction (LOC was 9.5° ± 1.9° (P < 0.001. At the most recent follow-up visit, mean ODI and VAS were 15.0 ± 14.4 and 2.4 ± 2.5, respectively and 24 cases (88.9% declared excellent or good clinical results. At the last follow-up visit, LOC had no significant correlation neither with VAS nor ODI. Conclusions In surgical treatment of thoracolumbar burst fractures, a medium-segment posterior spinal fixation, although cannot maintain the radiologic reduction of the fractured vertebrae efficiently, is not only associated with acceptable clinical outcome but also spare one lower intact lumbar segment and therefore recommended.

    2015-02-01

    To describe clinical use of computed tomography (CT) and hoof surface markers to facilitate internal fixation within the confines of the hoof wall. Retrospective case series. Horses (n = 16) that had CT-guided internal fixation of the distal phalanx (DP) or distal sesamoid bone (DSB). Drill bit entry point and direction were planned from CT image series performed on hooves with grids of barium paste dots at proposed entry and projected exit sites. Post-implantation CT images were obtained to check screw position and length as well as fracture reduction. Imaging, reduction, and surgical and general anesthesia times were evaluated. Outcome was recorded. Screw position and length were considered near optimal in all horses, with no consequential malposition of bits or screws. Fracture reduction was evident in all cases. Preoperative planning times (at least 2 CT image acquisitions and grid creation) ranged from 10 to 20 minutes. Surgery time ranged from 45 to 90 minutes (mean, 61 minutes) and general anesthesia time ranged from 115 to 220 minutes (mean, 171 minutes). The combination of CT and surface marker grids allowed accurate positioning of screws in clinical DP and DSB fractures. The technique was simple and rapid. An aiming device is useful for the technique. © Copyright 2014 by The American College of Veterinary Surgeons.

    The purpose of this study is to demonstrate the feasibility of computer-tomography-navigated closed reduction and percutaneous fixation (CRPF) in a patient with an externally rotated left acetabular fracture. After a follow-up of 18 months the patient was pain-free and had a normal range of motion in both hip joints. Radiologically, the fracture was fully consolidated, remodelled, and there were no signs of osteoarthritis. To our knowledge, CT-navigated CRPF of a rotated acetabular fracture has not been reported before. Further studies regarding the feasibility of the method are warranted(CRPF)

    Full Text Available Klippel-Trenaunay syndrome (KTS is a rare complex malformation characterized by the clinical triad of capillary malformations, soft tissue and bone hypertrophy, and venous/lymphatic malformation. Fractures of long bones in such cases are challenging to treat. A 12-year-old female with this syndrome presented with femoral shaft fracture of right thigh. She was initially kept on skeletal traction for two weeks and then she underwent closed reduction and immobilization with external fixator with uneventful intraoperative and postoperative period. Fracture united at four and half months.

    Forefoot fractures are frequently accompanied by severe soft tissue damage. Therefore, treatment should focus not only on fractures but also on soft tissue damage, for which external fixation can be used as a surgical option. A 63-year-old woman presented to the emergency clinic of our hospital with forefoot pain after a motorcycle accident. Comminuted fracture of the proximal part of the metatarsal was diagnosed. Because of the swollen foot and fracture comminution, an operation using the Ilizarov mini external fixator was performed to prevent further damage to the soft tissue. Weight-bearing was permitted seven weeks after the operation, and the extraction of the apparatus was performed nine weeks postoperatively. One year later, the patient had no pain and had returned to ballroom dancing, a hobby which she performed five days a week, with no difficulties. Our results suggest that the Ilizarov mini external fixator should be considered not only for temporary treatment, but also for the entire duration of treatment of first metatarsal fractures associated with severe soft tissue damage.

    A cooperative international project was conducted by the Idaho National Laboratory (INL) and the United Kingdom’s National Nuclear Laboratory (NNL) to integrate a capture coating with a high performance atomizing process. The initial results were promising, and lead to further trials. The somewhat longer testing and optimization process has resulted in a product that could be demonstrated in the field to reduce airborne radiological dust and contamination.

    Fractures of the tibia are one of the most commonly seen orthopedic injuries. Most of them result from a high velocity trauma. While intramedullary nailing of tibial diaphyseal fractures is considered as the golden standard form of treatment for such cases, many metaphyseal and metaphyseal-diaphyseal junction fractures can also be managed by nailing. Maintenance of alignment of such fractures during surgical procedure is often challenging as the pull of patellar tendon tends to extend the proximal fragment as soon as one flexes the knee for the surgical procedure. Numerous technical modifications have been described in the literature for successfully nailing such fractures including semi extended nailing, use of medial plates and external fixators among others. In this study, it was aimed to report two cases in which we used our ingenious method of applying external fixator for maintaining alignment of the fracture and aiding in the entire process of closed intramedullary nailing of metaphyseal tibial fractures by the conventional method. We were able to get good alignment during and after the closed surgery as observed on post-operative radiographs and believe that further evaluation of this technique may be of help to surgeons who want to avoid other techniques.

  4. Safe surgical technique: intramedullary nail fixation of tibial shaft fractures.

    2015-01-01

    Statically locked, reamed intramedullary nailing remains the standard treatment for displaced tibial shaft fractures. Establishing an appropriate starting point is a crucial part of the surgical procedure. Recently, suprapatellar nailing in the semi-extended position has been suggested as a safe and effective surgical technique. Numerous reduction techiques are available to achieve an anatomic fracture alignment and the treating surgeon should be familiar with these maneuvers. Open reduction techniques should be considered if anatomic fracture alignment cannot be achieved by closed means. Favorable union rates above 90 % can be achieved by both reamed and unreamed intramedullary nailing. Despite favorable union rates, patients continue to have functional long-term impairments. In particular, anterior knee pain remains a common complaint following intramedullary tibial nailing. Malrotation remains a commonly reported complication after tibial nailing. The effect of postoperative tibial malalignment on the clinical and radiographic outcome requires further investigation.

    We report a series of 42 patients reviewed at a mean of 19.6 months after treatment of distal tibial and pilon fractures using the AO distal tibia locking plate with a minimally invasive percutaneous plate osteosynthesis (MIPPO) technique. Mean time to union was 22.4 weeks. All fractures united with acceptable alignment and angulation. Two cases of superficial infection were noted, with one case of deep infection. Mean SF36 score was 85 and mean AOFAS score was 90 at a mean of 19 months follow-up. We report satisfactory outcomes with the use of the AO distal tibia locking plate in treatment of unstable distal tibial fractures. Eighty-nine percent of the patients felt that they were back to their pre injury status and 95% back to their previous employment.

    Full Text Available Background: Elastic intramedullary fixation is an established operative treatment for fractures in childhood, which is only exceptionally used in adults. A modified intramedullary fixation of midclavicular fractures in adults with titanium elastic nails is presented.Methods: The group was comprised of five adult patients with shortened midclavicular fractures. The prior conservative treatment had been ineffective in three cases, whereas poor functional outcome was expected in the other two, as a result of fracture shortening or instability. According to the new technique titanium elastic nails were first placed into the intramedullar channel of the distal fragment through the fracture, using a mini-open exposure. The nails were advanced retrogradely into the proximal fragment to achieve a stable fixation. The initial post-operative rehabilitation included pendulary exercises in a sling. Active exercises in the range of pain allowance were introduced after the operative wounds had been healed.Results: All fractures were consolidated in the physiological position. The patients were capable of painless movements with the shoulder on the operated side in the full range of motion after six weeks. One transitory complication in the form of skin and subcutaneous decubitus over the protruded nail tip was noted without an influence on the end result.Conclusions: The preliminary results in a limited number of patients showed efficient consolidation of the midclavicular fractures in adults treated with intramedullar titanium elastic nails. The functional results and low invasivity of the procedure support its further use in treatment of midclavicular fractures, which fail to heal conservatively, or which are expected to result in poor functional or cosmetic outcome.

    Elastic stable intramedullary nailing is increasingly used for surgical treatment of tibial shaft fractures, but frequently requires immobilization and delayed full weight-bearing. Therefore, external fixation remains interesting. The aim was to report clinico-radiological outcomes of monolateral external fixation for displaced and unstable tibial shaft fractures in children. All tibial fractures consecutively treated by monolateral external fixation between 2008 and 2013 were followed. Inclusion criteria included skeletal immaturity and closed and open Gustilo I fractures caused by a direct impact. Patients were seen until two years postoperatively. Demographics, mechanism of injury, surgical data and complications were recorded. Anteroposterior and lateral side radiographs were performed at each visit. Full-limb 3D reconstructions using biplanar stereroradiography was performed for final limb length and alignment measures. A total of 45 patients (mean age 9.7 years ± 0.5) were included. In all, 17 were Gustilo I fractures, with no difference between open and closed fractures for any data. Mean time to full weight bearing was 18.2 days ± 0.7. After 15 days, 39 patients returned to school. Hardware removal (mean time to union 15.6 weeks ± 0.8) was performed during consultation under analgesic gas. There were no cases of nonunion. No fracture healed with > 10° of angulation (mean 5.1° ± 0.4°). Leg-length discrepancy > 10 mm was found for six patients. This procedure can be a safe and simple surgical treatment for children with tibial shaft fractures. Few complications and early return to school were reported, with the limitations of non-comparative study. IV.

  8. Novel intramedullary-fixation technique for long bone fragility fractures using bioresorbable materials.

    Full Text Available Almost all of the currently available fracture fixation devices for metaphyseal fragility fractures are made of hard metals, which carry a high risk of implant-related complications such as implant cutout in severely osteoporotic patients. We developed a novel fracture fixation technique (intramedullary-fixation with biodegradable materials; IM-BM for severely weakened long bones using three different non-metallic biomaterials, a poly(l-lactide (PLLA woven tube, a nonwoven polyhydroxyalkanoates (PHA fiber mat, and an injectable calcium phosphate cement (CPC. The purpose of this work was to evaluate the feasibility of IM-BM with mechanical testing as well as with an animal experiment. To perform mechanical testing, we fixed two longitudinal acrylic pipes with four different methods, and used them for a three-point bending test (N = 5. The three-point bending test revealed that the average fracture energy for the IM-BM group (PLLA + CPC + PHA was 3 times greater than that of PLLA + CPC group, and 60 to 200 times greater than that of CPC + PHA group and CPC group. Using an osteoporotic rabbit distal femur incomplete fracture model, sixteen rabbits were randomly allocated into four experimental groups (IM-BM group, PLLA + CPC group, CPC group, Kirschner wire (K-wire group. No rabbit in the IM-BM group suffered fracture displacement even under full weight bearing. In contrast, two rabbits in the PLLA + CPC group, three rabbits in the CPC group, and three rabbits in the K-wire group suffered fracture displacement within the first postoperative week. The present work demonstrated that IM-BM was strong enough to reinforce and stabilize incomplete fractures with both mechanical testing and an animal experiment even in the distal thigh, where bone is exposed to the highest bending and torsional stresses in the body. IM-BM can be one treatment option for those with severe osteoporosis.

    In this study, we aimed to compare the functional and radiological results of intramedullary nailing and plate fixation techniques in the surgical treatment of distal tibia diaphyseal fractures close to the ankle joint. Between 2005 and 2011, 55 patients (32 males, 23 females; mean age 42 years; range 15 to 72 years) who were treated with intramedullary nailing (21 patients) or plate fixation (34 patients) due to distal tibia diaphyseal fracture were included in the study. The average follow-up period was 27.6 months (range, 12-82 months). The patients were evaluated with regard to nonunion, malunion, infection, and implant irritation. The AOFAS (American Orthopaedic Foot and Ankle Society) scale was used for the clinical evaluation. No statistically significant difference was found between the two surgical methods with respect to unification time, AOFAS score, accompanying fibula fracture, material irritation, and malunion. Nine patients had open fractures, and these patients were treated with plate fixation (p=0.100). Nonunion developed in three patients who were treated with plates. Infection occurred in one patient. Anterior knee pain was significantly higher in patients who were treated with intramedullary nails. There was no malunion in any patient. As the distal fragment is not long enough, plate fixation technique is usually preferred in the treatment of distal tibia diaphyseal fractures. In this study, we observed that if the surgical guidelines are followed carefully, intramedullary nailing is an appropriate technique in this kind of fracture. The malunion rates are not significantly increased, and it also has the advantages of being a minimally invasive surgery with fewer wound problems.

    The locking plate and percutaneous crossing metallic screws and crossing absorbable screws have been used clinically to treat intra-articular calcaneal fractures, but little is known about the biomechanical differences between them. This study compared the biomechanical stability of calcaneal fractures fixed using a locking plate and crossing screws. Three-dimensional finite-element models of intact and fractured calcanei were developed based on the CT images of a cadaveric sample. Surgeries were simulated on models of Sanders type III calcaneal fractures to produce accurate postoperative models fixed by the three implants. A vertical force was applied to the superior surface of the subtalar joint to simulate the stance phase of a walking gait. This model was validated by an in vitro experiment using the same calcaneal sample. The intact calcaneus showed greater stiffness than the fixation models. Of the three fixations, the locking plate produced the greatest stiffness and the highest von Mises stress peak. The micromotion of the fracture fixated with the locking plate was similar to that of the fracture fixated with the metallic screws but smaller than that fixated with the absorbable screws. Fixation with both plate and crossing screws can be used to treat intra-articular calcaneal fractures. In general, fixation with crossing metallic screws is preferable because it provides sufficient stability with less stress shielding.

    The technique of retrograde intramedullary fixation of fractures through open traumatic amputations has not been previously described. We performed a retrospective case series at a tertiary-care military hospital setting. Ten patients met inclusion criteria. All were male, and all were injured through improvised explosive device. Outcome measures included the incidence of fracture nonunion, osteomyelitis or acute infection, heterotopic ossification (HO), as well as successful prosthesis fitting and ambulation. Average time to fixation after injury and amputation closure was 11.7 and 12.2 days, respectively. Follow-up averaged 20.2 months. The radiographic union rate was 100%, and time to osseous union averaged 7.5 months. One patient had an amputation site infection requiring revision, but none of the nails was removed for infectious reasons. HO occurred in 7 patients, and 2 patients required revision for symptomatic HO. All patients were successfully fitted with prostheses and able to ambulate. To our knowledge, this is the only series in the literature to specifically describe retrograde intramedullary fixation of long bone fractures through the zone of traumatic amputation sites. The infectious risk is relatively low, whereas the union rate (100%) and successful prosthesis fitting are high. For patients with similar injuries, retrograde intramedullary fixation through the zone of amputation is a viable treatment option.

    2011-07-01

    Full Text Available Abstract Introduction The clinical outcome of hemiarthroplasty for proximal humeral fractures is not satisfactory. Secondary fragment dislocation may prevent bone integration; the primary stability by a fixation technique is therefore needed to accomplish tuberosity healing. Present technical comparison of surgical fixation techniques reveals the state-of-the-art approach and highlights promising techniques for enhanced stability. Method A classification of available fixation techniques for three- and four part fractures was done. The placement of sutures and cables was described on the basis of anatomical landmarks such as the rotator cuff tendon insertions, the bicipital groove and the surgical neck. Groups with similar properties were categorized. Results Materials used for fragment fixation include heavy braided sutures and/or metallic cables, which are passed through drilling holes in the bone fragments. The classification resulted in four distinct groups: A: both tuberosities and shaft are fixed together by one suture, B: single tuberosities are independently connected to the shaft and among each other, C: metallic cables are used in addition to the sutures and D: the fragments are connected by short stitches, close to the fragment borderlines. Conclusions A plurality of techniques for the reconstruction of a fractured proximal humerus is found. The categorisation into similar strategies provides a broad overview of present techniques and supports a further development of optimized techniques. Prospective studies are necessary to correlate the technique with the clinical outcome.

    This study was aimed to compare the outcomes of two operational methods used for the fixation of calcaneal fracture, the open reduction using a plate and the minimally invasive cannulated screw fixations. Thus, we attempted to find out as to which of these fixation regimens was therapeutically superior by assessing improvement in the restoration of foot functioning and estimating the biochemical indices that reflect bone recovery. A total of 492 calcaneal fracture patients admitted in our hospital from February, 2008 to February, 2012 were selected for the study and randomly divided into two groups of 246 cases each. They were treated with either open reduction using a plate or minimally invasive cannulated screw fixation procedures. After the operations, patients were followed up for 2 years and the outcomes including functional restoration of calcaneus, the post-operational complications, and measure of the biochemical indicators of bone recovery were compared. The patients who underwent plate fixation procedure showed the excellent and good rate of 76.8 %. The minimally invasive cannulated screw fixation led to the excellent and good rate of 82.5 %. The angle, width, and height of calcaneus observed in the last follow-up were also improved significantly in the two groups (p 0.05). The post-operative complications occurred with the rates of 14.2 and 4.9 % in the patients treated with the plate and the minimally invasive cannulated screw fixations, respectively. The length of stay and hospitalization costs in the plate fixation group were 9.16 ± 0.83 days and 12,639.74 ± 2,573.82 Chinese Yuan, respectively. In comparison, in cannulated screw fixation group, the length of hospital stay (7.03 ± 0.52 days) and its cost (6,795.01 ± 996.53 Chinese Yuan) were significantly lower. Serum bone alkaline phosphatase and tartrate-resistant acid phosphatase-5b levels measured at the last follow-up examination were significantly altered (p 0.05). Plate screw and the

    Plastic surgeons specialize in working closely with other surgical colleagues to help solve clinical problems. In this case, we performed surgical stabilisation of a large flail chest fragment in conjunction with the cardiothoracic surgical team, using the mini-plating set more commonly used for hand fracture fixation. The use of this fixation system for flail chest has not previously been described, but offers advantages over other reported methods, primarily by dispensing with the need for an extensive thoracotomy incision and by providing robust stabilisation without the presence of prominent hardware.

    Introduction: Supracondylar fracture of the humerus is the most common fracture around the elbow in children. Pinning with Kirschner wires (K-wires) after open or closed reduction is generally accepted as the primary treatment modality. However, it comes with the risk of persistent instability and if the K-wire is not inserted properly, it may cause displacement and varus deformity. We present our two-year experience with a new technique of lateral external fixation and K-wiring of the humeral supracondylar fracture. Materials and Methods: A total of seven children with irreducible Gartland Type III supracondylar humeral fracture were treated with closed reduction and lateral external fixation and lateral Kirschner wiring. Patients with ipsilateral radial or ulnar fracture, open fracture and presence of neurovascular impairment pre-operatively were excluded. All the patients were followed up at one, three and six weeks and three and six months. The final outcomes were assessed based on Flynn's criteria. Results: All the patients achieved satisfactory outcomes in terms of cosmetic and functional aspects. All patients except one (85.5%) regained excellent and good cosmetic and functional status. One patient (14.3%) sustained pin site infection which resolved with oral antibiotic (Checketts- Otterburn grade 2). There was no neurological deficit involving the ulnar nerve and radial nerve. Conclusion: The introduction of lateral external fixation and lateral percutaneous pinning provide a promising alternative method for the treatment of humeral supracondylar fracture. This study demonstrates that it has satisfactory cosmetic and functional outcomes with no increased risk of complications compared to percutaneous pinning.

    Full Text Available Introduction: Supracondylar fracture of the humerus is the most common fracture around the elbow in children. Pinning with Kirschner wires (K-wires after open or closed reduction is generally accepted as the primary treatment modality. However, it comes with the risk of persistent instability and if the K-wire is not inserted properly, it may cause displacement and varus deformity. We present our two-year experience with a new technique of lateral external fixation and K-wiring of the humeral supracondylar fracture. Materials and Methods: A total of seven children with irreducible Gartland Type III supracondylar humeral fracture were treated with closed reduction and lateral external fixation and lateral Kirschner wiring. Patients with ipsilateral radial or ulnar fracture, open fracture and presence of neurovascular impairment pre-operatively were excluded. All the patients were followed up at one, three and six weeks and three and six months. The final outcomes were assessed based on Flynn's criteria. Results: All the patients achieved satisfactory outcomes in terms of cosmetic and functional aspects. All patients except one (85.5% regained excellent and good cosmetic and functional status. One patient (14.3% sustained pin site infection which resolved with oral antibiotic (CheckettsOtterburn grade 2. There was no neurological deficit involving the ulnar nerve and radial nerve. Conclusion: The introduction of lateral external fixation and lateral percutaneous pinning provide a promising alternative method for the treatment of humeral supracondylar fracture. This study demonstrates that it has satisfactory cosmetic and functional outcomes with no increased risk of complications compared to percutaneous pinning.

    Full Text Available Background: Tibial plateau fractures, intra-articular in nature and caused by high-velocity trauma, constitute approximately 1% of all fractures. Primary goal in the management of proximal tibial articular fracture aims for a stable, congruous, pain-free, mobile joint. Objective: To study the technique, results, and complications of percutaneous cancellous screw fixation for tibial plateau fractures. Materials and Methods: Twenty-three men and seven women aged 18-65 years (mean = 36.8 years underwent closed reduction and percutaneous screw fixation for closed tibial plateau fractures with <5 mm depression. According to the Schatzker classification, patients were grouped as type I (n = 18, type II (n = 4, type III (n = 0, type IV (n = 8, type V (n = 2, and type VI (n = 1. Closed reduction was achieved by manual ligamentotaxis technique under image intensifier control and fixed percutaneously with two cancellous screws (6.5 mm with or without washers in a parallel fashion. Results: Functional outcome was evaluated using the Mason Hohl evaluation system. A total score of 19-24 was considered as excellent, 13-18 as good, 7-12 as fair, and <6 as poor. Outcomes were excellent in 10 patients, good in 15, fair in 4, and poor in 1 patient. Patients were allowed partial weight bearing with walker after 1 month and full weight bearing after radiological union in approximately 3-4 months. The mean period of hospital stay was 5 (range 2-15 days. All the fractures united radiologically after a mean of 3 (range 2.5- 5 months. Patients were evaluated at a mean of 3 years after injury. No patient had any complication like infection, wound dehiscence, or hardware problem. Conclusion: Percutaneous cancellous screw fixation for closed tibial plateau fractures is minimally invasive. It reduces hospital stay and cost, enables early mobilization with minimal instrumentation, and achieves satisfactory outcomes.

    To describe the outcome of bone plate fixation of distal radius and ulna fractures in toy breed dogs treated with conventional bone plates. Records of 15 toy breed dogs with distal radius and ulna fractures were retrospectively reviewed for signalment, method of fixation, complications and clinical and radiographic assessments. A telephone-based owner questionnaire was conducted to determine long-term function and client satisfaction. Age ranged from 4 months to 6 years. Body weight ranged from 1 to 4 kg. Dynamic compression plates were used in 13 dogs and veterinary cuttable plates were used in 2 dogs as the means of fixation. Full radiographic and clinical follow-up data were available for 10 dogs and follow-up was performed between 6 and 8 weeks postoperatively. At that time, all fractures had healed and return to function was considered excellent in all 10 dogs. Five dogs did not return for hospital evaluation because they were judged by their owners to be free of lameness. In two cases, owners could not be contacted by telephone, but the referring veterinarians reported the dogs to be asymptomatic. No major complications occurred. Conventional bone plates are suitable choices for stabilisation of distal radius and ulna fractures in toy breed dogs and are not necessarily correlated with high rates of complication. © 2016 Australian Veterinary Association.

    Full Text Available Abstract Introduction Hip fracture fixation surgery in patients with below-knee amputations poses a challenging problem to the surgeon in terms of obtaining traction for reduction of the fracture. The absence of the foot and part of the leg in these patients makes positioning on the fracture table difficult. We highlight this difficult problem and suggest techniques to overcome it. Case presentation A 73-year-old man with bilateral below-knee amputations presented with a history of fall. Radiographs revealed an inter-trochanteric fracture of the femur. A dynamic hip screw fixation was planned for the fracture but the dilemma was on how to position the patient on the fracture table for the surgery. Special attention was needed in positioning the patient and in surgical fixation of the fracture. Conclusion Hip fracture fixation in patients with below-knee amputations poses a special problem in positioning for fracture reduction and fixation. In this case report, we share our experience and suggest techniques to use when encountering this difficult problem.

    The aim of this study was to investigate the outcome of 352 (71 males) patients with trochanteric fractures that were treated with the TARGON® PF nail. The mean age was 83 years. According to the Jensen classification, there were 35 cases in type 1,94 cases in type 2,75 in type 3,63 in type 4 and 85 in type 5. Postoperative all patients were allowed to fully weight bear from the first postoperative day. Clinical and radiological data were collected at regular time intervals. The average waiting time to surgical reconstruction for the 352 cases was 3.5 days (1-7). The mean length of hospital stay was 14 days (5-22). The operative times ranged from 11 to 125 minutes with an average time of 32 minutes. Fifty percent of the patients regained their mobility to their pre-injury level at the final follow up. Out of 310 patients (88%) who were available for radiographie assessment, all fractures united except one case. 300 (85%) of the lag screws were placed in the inferior area in the anteroposterior view and in the central area in the lateral view (IM), which is regarded as the optimal position. The lag screws back-slided between 0 and 19 mms with an average of 6 mm. Sliding distance of the lag screw for over 10 mm was seen in 42 cases (13%). Varus collapse of the femoral head-and-neck greater than 10° was observed in 6 cases. Postoperative complications developed in 6 cases (1.7%), including wound infection in two cases, and secondary fracture at the subtrochanteric region, nonunion, back-out of the guiding sleeve and medial perforation of the lag screw, each in one case. The presented case series indicates that the TARGON® PF system is an effective and safe internal fixation device for trochanteric proximal femoral fractures. Further, prospective comparative evidence regarding the use of this system is needed to analyse and validate the presented clinical impression of our centre. Copyright © 2011 Elsevier Ltd.

    The present prospective study examined the utility of the intraoperative tap test/technique for distal tibiofibular syndesmosis in the diagnosis of deltoid ligament rupture and compared the outcomes of transsyndesmotic fixation to deltoid ligament repair with suture anchor. This diagnostic technique was performed in 59 ankle fractures with suspected deltoid ligament injury. The width of the medial clear space of 59 cases was evaluated to assess the sensitivity and specificity. Those with deltoid ligament rupture were randomly assigned to 2 groups and treated with deltoid ligament repair with a suture anchor or with syndesmosis screw fixation. All the patients were assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, short-form 36-item questionnaire (SF-36), and visual analog scale (VAS). The tap test was positive in 53 cases. However, surgical exploration demonstrated that 51 cases (86.4%) had a combined deltoid ligament injury and fracture. The sensitivity and specificity of the tap test was 100.0% and 75.0%, respectively. Finally, 26 cases (96.3%) in the syndesmosis screw group and 22 (91.7%) in the deltoid repair group were followed up. No statistically significant differences were found in the AOFAS ankle-hindfoot scale score, SF-36 score, or VAS score between the 2 groups. The malreduction rate in the syndesmosis screw group was 34.6% and that in the deltoid repair group was 9.09%. The tap test is an intraoperative diagnostic method to use to evaluate for deltoid ligament injury. Deltoid ligament repair with a suture anchor had good functional and radiologic outcomes comparable to those with syndesmotic screw fixation but has a lower malreduction rate. We did not encounter the issue of internal fixation failure or implant removal. Copyright © 2017 The American College of Foot and Ankle Surgeons. Published by Elsevier Inc. All rights reserved.

    Displaced intra-articular calcaneus fractures (DIACFs) are the most common type of calcaneus fracture. The differences in therapeutic effectiveness between cannulated screw fixation (CSF) and plate fixation are still unclear. Thus, in this meta-analysis, we evaluated the therapeutic effectiveness of these two fixation methods. We searched for all publications on DIACFs fixated with cannulated screws or plates in the following electronic databases: Pubmed, Cochrane, Embase and CNKI. Only randomized controlled studies were included. The Cochrane Handbook for Systematic Reviews of Interventions (version 5.1.0) was applied for analysis. The primary outcomes were American Orthopedic Foot and Ankle Society score (AOFAS), improvement of Bohler's angle, improvement of Gissane's angle and the width of the calcaneus. Outcomes were reported as the standard mean difference (SMD) or relative risk (RR) with the 95% confidence interval (CI). A random effects model was used to assess the pooled data. Five randomized controlled studies met our inclusion criteria, and a total of 707 patients were involved. There was no statistically significant difference between the cannulated screw fixation group and the plate fixation group in terms of excellent and good AOFAS scores (RR = 1.01, 95%CI 0.91 to 1.13, P = 0.79), improvement of Bohler's angle (SMD = 0.12, 95%CI -0.03 to 0.28, P = 0.12), improvement of Gissane's angle (SMD = 0.09, 95%CI -0.28 to 0.26, P = 0.30), or the width of the calcaneus (SMD = -0.07, 95%CI -0.24 to 0.10, p = 0.45). Compared with plate fixation, CSF showed a significant reduction in the duration of surgery (SMD = -1.74, 95%CI, -3.35 to -0.13, P = 0.03) and rate of complications (RR = 0.25, 95%CI, 0.15 to 0.44, P<0.00001). Cannulated screw fixation and plate fixation have similar fixation effectiveness and functional outcomes in the treatment of displaced intra-articular calcaneus fractures. Due to the shorter duration of surgery and

    Full Text Available There is a high incidence of vertebral burst fractures following low velocity trauma in the elderly. Treatment of unstable vertebral burst fractures using the same principles like in stable vertebral burst fractures may show less favourable results in terms of fracture reduction, maintenance of reduction and cement leakage. In order to address these shortcomings this study introduces cementless fixation of unstable vertebral burst fractures using internal fixators and expandable intravertebral titanium mesh cages in a one-stage procedure via minimum-invasive techniques.A total of 16 consecutive patients (median age 76 years, range 58-94 with unstable thoracolumbar burst fractures and concomitant osteoporosis were treated by an internal fixator inserted via minimum invasive technique one level above and below the fractured vertebra. Fracture reduction was achieved and maintained by transpedicular placement of two titanium mesh cages into the fractured vertebral body during the same procedure. Intra- and postoperative safety of the procedure as well as analysis of reduction quality was analysed by 3D C-arm imaging or CT, respectively. Clinical and radiographic follow-up averaged 10.4 months (range 4.5-24.5.Stabilization of the collapsed vertebral body was achieved in all 16 cases without any intraoperative complication. Surgical time averaged 102 ± 6.6 minutes (71-194. The postoperative kyphotic angle (KA and Cobb angle revealed significant improvements (KA 13.7° to 7.4°, p < 0.001; Cobb 9.6° to 6.0°, p < 0.002 with partial loss of reduction at final follow-up (KA 8.3°, Cobb 8.7°. VAS (Visual Analogue Scale improved from 7.6 to 2.6 (p < 0.001. Adjacent fractures were not observed. One minor (malposition of pedicle screw complication was encountered.Cementless fixation of osteoporotic burst fractures revealed substantial pain relief, adequate maintenance of reduction and a low complication rate.

    Condyle fractures are common in children and are increasingly treated with open reduction. Three-dimensional printing has developed into an important method of assisting surgical treatment. This report describes the case of a 14-year-old patient treated for a right condyle fracture at the authors' hospital. Preoperatively, the authors designed a surgical guide using 3-dimensional printing and virtual surgery. The 3-dimensional surgical guide allowed accurate alignment of the fracture using Kirschner wire without additional dissection and tissue injury. Kirschner wire fixation augmented by 3-dimensional printing technology produced a good outcome in this adolescent condyle fracture.

    2006-01-01

    Intramedullary fixation of fibular fractures has been reported in the literature. Its advantages include ease of fixation as well as minimal soft tissue disruption. Various implants have been described, including the Inyo nail and Rush rods. Several studies have examined their use in older people with osteoporotic bone as well as in instances where soft tissue preservation is of concern. To our knowledge, no technique has been described using flexible titanium elastic nails (TENS) (Synthes; Paoli, PA). We illustrate such a technique as well as a case report that demonstrates our experience. Insertion of flexible titanium elastic nails requires attention to detail with preservation of the peroneal tendons and their sheath. While such a construct cannot control rotation, it can preserve length as well as prevent varus and valgus displacement. Future endeavors could focus on the biomechanical principles of intramedullary fibular fixation with TENS nails.

    Tibial shaft fractures comprise a large portion of operatively treated long bone fractures, and present with the highest rate of open injuries. Intramedullary fixation has become the standard of care for both open and closed injuries. The rates of short term complications and hospital length of stay for open and closed fractures treated with intramedullary fixation is not fully known. Previous series on tibia fractures were performed at high volume centers, and data were not generalizable, further they did not report on length of stay and the impact of preoperative variables on infections, complications and reoperation. We used a large surgical database to compare these outcomes while adjusting for preoperative risk factors. Data were extracted from the ACS-NSQIP database from 2005 to 2014. Cases were identified based on CPT codes for intramedullary fixation and categorized as closed vs open based on ICD9 code. In addition to demographic and case data, primary analysis examined correlation between open and closed fracture status with infection, complications, reoperation and hospital length of stay. Secondary analysis examined preoperative variables including gender, race, age, BMI, and diabetes effect on outcomes. There were 272 cases identified. There were no significant demographic differences between open and closed tibia fracture cases. Open fracture status did not increase the rate of infection, 30day complications, reoperation, or length of stay. The only preoperative factor that correlated with length of stay was age. There was no correlation between BMI, presence of insulin dependent and nondependent diabetes, and any outcome measure. When considering the complication rates for open and closed tibial shaft fractures treated with intramedullary fixation, there is no difference between 30-day complication rate, length of stay, or return to the operating room. Our reported postoperative infection rates were comparable to previous series, adding validity to

    Abstract Transpedicular screw (TPS) fixation in unstable thoracic and lumbar (TL) spine fractures remains technically difficult because of destroyed anatomical landmarks, unstable gross segments, and discrepancies in anatomic orientation using conventional anatomic landmarks, fluoroscopic guidance, or computed tomography (CT)-based navigation. In this study, we evaluated the safety and accuracy of TPS placement under intraoperative computed tomography (iCT) navigation in managing unstable TL spine fractures. From 2010 to 2013, we retrospectively reviewed the Spine Operation Registry records of patients who underwent posterior instrumented fusion to treat unstable TL spine fractures via the iCT navigation system. An unstable spine fracture was identified as AO/Magerl classification type B or type C. In all, 316 screws in 37 patients with unstable TL spine fractures were evaluated and involved 7 thoracic, 23 thoracolumbar junctional, and 7 lumbar fractures. The accuracy of TPS positioning in the pedicle without breach was 98% (310/316). The average number of iCT scans per patient was 2.1 (range 2–3). The average total radiation dose to patients was 15.8 mSv; the dose per single level exposure was 2.7 mSv. The TPS intraoperative revision rate was 0.6% (2/316) and no neurovascular sequela was observed. TPS fixation using the iCT navigation system obtained a 98% accuracy in stabilizing unstable TL spine fractures. A malplaced TPS could be revised during real-time confirmation of the TPS position, and no secondary operation was required to revise malplaced screws. The iCT navigation system provides accurate and safe management of unstable TL spine fractures. In addition, operating room personnel, including surgeons and nurses, did not need to wear heavy lead aprons as they were not exposed to radiation. PMID:25997042

    Full Text Available Surgical fixation of hip fractures in patients with below knee amputation is challenging due to the difficulty in obtaining optimal traction for reduction of the fracture. Surgeons may face difficulty in positioning such patients on the traction table due to the absence of the foot and distal lower limb. There are several techniques described to overcome this technical difficulty. In this case report, we present a case of a 64-year old gentleman with bilateral below knee amputation presenting with a comminuted right intertrochanteric fracture. We highlight a simple and effective method of applying skin traction to obtain adequate reduction for hip fracture fixation.
