    Full Text Available 87-year-old female underwent open reduction of distal femoral fracture and internal fixation with locking compression plate and bone graft. She was operated for ipsilateral proximal femoral fractures and stabilized by intramedullary interlocked nail 5 years ago. She developed stress fracture proximal to locked plate. We inserted Huckstep nail after removal of the previous operated proximal femoral nail without removing the remaining plate and screws. At 15 month followup the fractures have united. The Huckstep nail has multiple holes available for screw fixation at any level in such difficult situations.

    The treatment of supracondylar fractures of the femur with an intramedullary nail presents some theoretical advantages. Compared to plate osteosynthesis, intramedullary fixation requires less extensive dissection and is biomechanically more favorable. In the elderly patient, these characteristics seem important since bone quality, extensive procedures and bone grafting remain problematic. Since August 1994 we have treated 16 consecutive closed fractures of the distal femur (A.O. type: 7 A.1, 2 A.3, 4 C.1, and 3 C.2) with the Green-Seligson-Henry intramedullary retrograde supracondylar nail. Twelve elderly and osteoporotic patients had suffered low-energy trauma, three young patients had been involved in a traffic accident and one other young patient had attempted suicide. The operative technique, complications and results are described. All fractures healed within a few months (2 to 7) without bone grafting. No failure of the fixation material and no deep infection were encountered. With most elderly patients the functional result was judged satisfactory, considering the population studied. Intraoperative determination of alignment and avoiding shortening were the major difficulties, especially with long oblique or comminuted fractures. Two major complications were encountered in the young population. In one instance nail protrusion in the intercondylar notch caused a deep patellar cartilage erosion and sympathetic distrophy leading to a 15 degrees flexion deformity. Another young patient needed a quadriceps release at the fracture site and subsequently a femoral valgus osteotomy in order to achieve an acceptable final result. In elderly osteoporotic patients presenting an isolated supracondylar fracture, antegrade nailing remains the "safest" technique by avoiding an unnecessary arthrotomy. When previous hip or knee surgery precludes the use of antegrade nailing techniques or when the fracture extends into the intercondylar region, retrograde supracondylar nailing

    Full Text Available BACKGROUND Interlocking intramedullary nailing is suitable for comminuted femoral isthmus fractures, but for non-comminuted fractures its benefit over unlocked nailing is debatable. This study was undertaken to compare outcomes of interlocking nailing versus k-nail in such fractures. MATERIALS AND METHODS 40 cases of noncomminuted femoral isthmus fractures treated with interlocking nailing and K-nail from April 1, 2015, to December 1, 2016, were reviewed. Radiological and clinical union rates, bony alignment, complication and knee function were investigated. RESULTS There was no statistical significant difference with regard to union rate, implant failure, infection and fracture alignment in both study groups. Open fixation with K-nail is technically less demanding and requires less operating time; additionally, there is no exposure to radiation and cost of the implant is cheaper. CONCLUSION We therefore conclude that unlocked nailing is still useful for the management of noncomminuted isthmus fractures of the femur.

    Full Text Available The aim of this paper is to document a rare case of construct failure in a 68-year old Filipina who sustained an atypical femoral fracture (AFF in her left subtrochanteric area. The patient previously had a 40-month history of alendronate 70mg + vitamin D 5600u therapy for osteoporosis and underwent closed intramedullary nailing for the AFF. Six months postoperatively, she began to experience progressive pain in her operated thigh. Radiographs revealed a broken nail at the proximal screw hole and non-union of the AFF. The patient was treated with exposure of the fracture site, removal of the broken device, exchange intramedullary nailing, and iliac bone grafting. She had radiographic and clinical union and was full weight bearing after three months.

    Full Text Available Aim: To study the functional and anatomical outcome of Inter trochanteric fractures of femur treated with Short femoral nail. Method: This was retrospective study carried out in which 60 patients (50 Male & 10 Female of 5th to 8th decade of life who underwent Short femoral nail fixation for both Stable & unstable Inter Trochanteric fractures. From the records each patient data was assessed for time required for mobilization, average fracture healing time, degree and grade of hip range of movements, complications, anatomical reduction achieved using Short femoral nail fixation. Results: 55 cases achieved Anatomical reduction. Good to Excellent Hip range of Motion was in 55 (90 % cases. Fracture union was seen in all cases. No evidence of Z Effect, AVN of femoral head, Implant failure, Fracture of femoral shaft below the Nail tip was seen in any case, However Reverse Z Effect was seen in 4 & shortening of less than 2 cm was seen in 2 cases, External rotation of 10 degree was seen in1 case. Average fracture Union time was 14 weeks. Conclusion: Short femoral nail appears to be better implant for fixation of both Stable & unstable Inter Trochanteric fractures as it fulfills the biomechanical demands being minimally invasive, less blood loss , it prevents excessive varus collapse at fracture site, produces less stress riser effect below the nail tip, Short operative time, Facilitates early mobilization & functional recovery of patients. But Anatomical fracture reduction & optimal implant placement are absolutely must for better results.

  10. A Novel Closed Method to Retrieve Broken Teflon Tube During Intramedullary Nailing in Proximal Humeral Fracture

    Full Text Available Broken medullary tubes have been used for intramedullary (IM nailing of femoral and tibial fractures. In these reported cases, fragments of the medullary tube were retrieved by opening the fracture sites or left in situ, which might jeopardize periosteal blood supply. We herein present the case of a 58-year-old woman who underwent IM nailing for proximal humeral fracture, which was complicated by breakage of the medullary tube intraoperatively. Different instruments including guide rods, straight forceps, and cement extract hook were used to retrieve the retained fragments from the medullary canal, but these attempts were unsuccessful. Finally, the fragments were successfully removed using an anterior cruciate ligament (ACL ENDOBUTTON depth gauge. This case highlights that medullary tubes can break during humeral IM nailing, which could be minimized by ensuring integrity of the medullary tube prior to surgery and disposing medullary tubes with more than 100 exposures. A novel method of using ACL ENDOBUTTON depth gauge to retrieve retained tube fragments is recommended because of its long and slim design.

    Full Text Available While antegrade nailing for proximal and diaphyseal femur fractures is a commonly utilized fixation method with benefits including early mobilization and high rates of fracture union, both intraoperative and postoperative complications may occur. Intraoperative errors include leg length discrepancy, anterior cortical perforation, malreduction of the fracture, and neurovascular injury, and postoperative complications include nonunion, malunion, infection, and hardware failure. This case series reviews complications affecting the distal femur after intramedullary nailing including fracture surrounding a distal femoral interlocking screw (Case #1, nonunion after dynamization with nail penetration into the knee joint (Case #2, and anterior cortical perforation (Case #3. Prevention of intraoperative and postoperative complications surrounding intramedullary nailing requires careful study of the femoral anatomy and nail design specifications (radius of curvature, consideration of the necessity of distal interlocking screws, the need for close radiographic follow-up after nail placement with X-rays of the entire length of the nail, and awareness of possible nail penetration into the knee joint after dynamization.

    Full Text Available Background: The need for operative fixation of pediatric femoral fractures is increasingly being recognised in the present decade. The conventional traction and casting method for management of pediatric femoral fractures is giving way for the operative stabilisation of the fracture. Methods : Thirty five pediatric patients in age group 6-14 years with diaphyseal femoral fractures were stabilised with two titanium nails. Patients were followed up clinically and radiologically for two years. The final results were evaluated using the criteria of Flynn et al. Technical problems and complications associated with the procedure were also analysed. Results : Overall results observed were excellent in 25, satisfactory in 8 and poor in 2 patients. Hospital time averaged 12.30 days in the series. All the fractures healed with an average time to union of 9.6 (6-14.4 weeks. Return to school was early with an average of 7.8 weeks. The soft tissue discomfort near the knee produced by the nails ends was the most common problem encountered. Shortening was observed in three cases and restriction of knee flexion in 5 patients. There was no delayed union, infection or refractures. Per operative technical problems included failure of closed reduction in 2 cases and cork screwing of nails in one case. Conclusion : We believe that with proper operative technique and aftercare TENs may prove to be an ideal implant for pediatric femoral fracture fixation. The most of the complication associated with the procedure are infact features of inexact technique and can be eliminated by strictly adhering to the basic principles and technical aspects.

    This retrospective study aims to evaluate the efficacy of flexible intramedullary (IM) nails as a fixation device of paediatric femoral shaft fractures. A total of 36 children with 37 closed fractures were treated by this method. The patients ranged in age from 7.2 to 13.5 years and the mean follow-up was 25.5 months. All patients had open femoral growth plates at the time of surgery. All fractures united and none of the patients needed re-operation. Complications included pain/irritation at the insertion site, superficial wound breakdown and one case of delayed union. No major complications were recorded. After nail removal, all children had full range of hip and knee motion. At final follow-up, although radiographs revealed that 44% of the children had malalignment at the fracture site in one or both planes, none of the children presented with clinical malalignment of the fractured limb. Maximum angulation that was calculated on the coronal plane was 5 degrees into varus and on the sagittal plane 7 degrees of anterior angulation (apex posteriorly). Leg-length discrepancy was assessed clinically and radiographically when needed. A total of 50% of the children had a leg-length inequality but none of them complained of a functional problem. Flexible nailing of diaphyseal fractures of the femur is a reliable method with a small learning curve and allows early mobilisation. Most of our minor complications were technique related and could be avoided. Copyright 2009 Elsevier Ltd. All rights reserved.

    Full Text Available Nonunion of long bones fixed with nails may result in implant failure. Removal of a broken intramedullary nail may be a real challenge. Many methods have been described to allow for removal of the broken piece of the nail. In this paper, we are reviewing the different techniques to extract a broken nail, classifying them into different subsets, and describing a new technique that we used to remove a broken tibial nail with narrow canal. Eight different categories of implant removal methods were described, with different methods within each category. This classification is very comprehensive and was never described before. We described a new technique (hook captured in the medulla by flexible nail introduced from the locking hole which is a valuable technique in cases of nail of a small diameter where other methods cannot be used because of the narrow canal of the nail. Our eight categories for broken nail removal methods simplify the concepts of nail removal and allow the surgeon to better plan for the removal procedure.

    1997-10-01

    We classified human femoral intramedullary architecture into 3 types. The cortex in the first type is thick and the medullary canal narrow with an even and smooth translation towards the metaphysis. In the second type, the cortex is thin and the canal wider, also evenly distributed along the entire length, while in the third type the canal narrows just distal to the subtrochanteric region and similarly a few centimeters distally. Some medullary canals of the second type do not allow dynamic nailing, while canals of the third type presents some difficulties for unreamed nails. Most medullary canals belong to the first and second type and only few belong to type three. We performed comparative experimental loading in 11 pairs of cadaveric fractured femora fixed with static and dynamic nailing. Dynamic nailing was found to behave as safely as static ones in the presence of a sound femoral shaft central and peripheral to the fracture with a length twice the diameter of the femur at the fracture level. This could be checked intraoperatively with gentle rotation under image intensifier. In a clinical series, dynamic nailing was performed in about one quarter of the patients with femoral shaft fractures (18 of 72 patients) with excellent results.

    Full Text Available A 19-year-old female patient sustained a closed spiral midshaft femoral fracture and subsequently underwent femoral intramedullary nail insertion. At followup she complained of difficulty in walking and was found to have a unilateral in-toeing gait. CT imaging revealed 30 degrees of internal rotation at the fracture site, which had healed. A circumferential osteotomy was performed distal to the united fracture site using a Gigli saw with the intramedullary femoral nail in situ. The static distal interlocking screws were removed and the malrotation was corrected. Two further static distal interlocking screws were inserted to secure the intramedullary nail in position. The osteotomy went on to union and her symptoms of pain, walking difficulty, and in-toeing resolved. Our paper is the first to describe a technique for derotation osteotomy following intramedullary malreduction that leaves the intramedullary nail in situ.

    Full Text Available ABSTRACT Proximal femoral nails with a helical blade are a new generation of implants used for treating transtrochanteric fractures. The blade design provides rotational and angular stability for the fracture. Despite greater biomechanical resistance, they sometimes present complications. In the literature, there are some reports of cases of perforation of the femoral head caused by helical blades. Here, a clinical case of medial migration of the helical blade through the femoral head and acetabulum into the pelvic cavity is presented.

    Many techniques have been employed to facilitate intramedullary nailing of femur fractures. Maintaining limb length during the operation can be difficult. The authors describe the use of distal femoral fine wire skeletal traction as a technique to maintain reduction while allowing intramedullary nailing of femur fractures. This technique is safe, is effective, and negates the need for a fracture table or an assistant. Copyright 2016, SLACK Incorporated.

    In many low and middle-income countries (LMICs) SIGN nail is commonly used for antegrade femoral intramedullary (IM) nailing, using a start site either at the tip of the greater trochanter or piriformis fossa. While a correct start site is considered an essential technical step; few studies have evaluated the impact of using an erroneous start site. This is particularly relevant in settings with limited access to fluoroscopy to aid in creating a nail entry point. The purpose of this study was to evaluate the impact of antegrade SIGN IM nailing start site on radiographic alignment and health-related quality of life. In this prospective cohort study, adult patients with proximal femur fractures (OTA 32, subtrochanteric zone) treated with antegrade IM SIGN nail at Muhimbili Orthopaedic Institute (MOI), Dar es Salaam, Tanzania were enrolled. Start site was determined on the immediate postoperative X-ray and was graded on a continuous scale based on distance of the IM nail center from the greater trochanteric tip. The primary outcome measurement was coronal alignment on the post-operative x-ray. The secondary outcomes were reoperation rates, RUST scores and EQ5D scores at one year follow-up. Seventy-nine patients were enrolled. 50 of them (63.3%) had complete data at 1year and were included in the final data analysis. Of the fifty patients, nine (18%) had IM nails placed laterally, 26 (52%) medially and 15 (30%) directly over the tip of the greater trochanter. Compared to a start site at the tip or medial to the greater trochanter, a lateral start site was 9 times more likely to result in a varus malalignment (95% CI: 1.42-57.70, p=0.021). Lateral start site was associated with varus malalignment. Although lateral start site was not significantly associated with reoperation, varus deformity was associated with higher reoperation rates. Surgeons should consider avoiding a start site lateral to the tip of the greater trochanter or allow the nail to rotate to avoid

    While antegrade nailing for proximal and diaphyseal femur fractures is a commonly utilized fixation method with benefits including early mobilization and high rates of fracture union, both intraoperative and postoperative complications may occur. Intraoperative errors include leg length discrepancy, anterior cortical perforation, malreduction of the fracture, and neurovascular injury, and postoperative complications include nonunion, malunion, infection, and hardware failure.

    Objectives To compare the long-term functional and radiographic outcomes of the proximal femoral nail antirotation-Asia (PFNA-II) and INTERTAN nail (IT) in the management of intertrochanteric femoral fractures (IFFs) (AO/OTA Type 31A1.1-A2.3) in elderly patients with primary osteoporosis. Methods A retrospective comparative study was performed in our institution. From January 2009 to March 2012, 243 patients with osteoporosis (243 hips) with IFFs (AO/OTA Type 3.1A1.1-A2.3) underwent repair with either a PFNA-II or IT. Follow-up assessments were performed 1, 3, 6, 9, and 12 months postoperatively and every year thereafter. All implant position changes were noted. Patient-related functional outcomes were evaluated based on the Harris hip score. Results In total, 174 patients with osteoporosis (IT, n = 86; PFNA-II, n = 88) were evaluated during a mean follow-up period of 40 months (range, 38-60 months). An increased risk of femoral shaft fracture after implant removal was observed at month 9 of follow-up in 0.0% and 4.4% of the IT and PFNA-II groups, respectively. This difference remained over time with rates of 1.1% and 6.8%, respectively, at the last follow-up. Conclusion The IT nail appears to be a reliable implant in the management of IFFs (AO/OTA Type 3.1A1.1-A2.3) in elderly patients with primary osteoporosis.

    Proximal femoral nail antirotation (PFNA) device is an intramedullary nail system designing for the treatment of trochanteric fractures. It is composed of a helical neck blade, a nail and a distal locking bolt. There were some reports of femoral shaft fractures even after the fractures were healed. The stress shielding effects of the PFNA device made of stiff titanium alloy on the bone-remodeling behavior of the host femur and the uneven distribution of interface shear stress may contribute to this complication. Recently, a new class of composite called functionally graded material (FGM) was developed, that consisted a gradual pattern of material composition and/or microstructures, and was introduced in dental implant and cementless hip stem. Accordingly, in this paper, we hypothesized that FGM might be used as the material of the nail in PFNA device with the material composition of the nail gradually shifting from more stiff at the proximal side of the femur to more flexible 'iso-elastic' towards the distal side. This hypothesis can be evaluated from the long-term remodeling behavior of host femur and the stress distributions in the PFNA device and bone. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Proximal femoral fracture rates are increasing due to osteoporosis and traffic accidents. Proximal femoral nails are routinely used in the treatment of these fractures in the proximal femur. To compare various combinations and to determine the ideal proximal lag screw position in pertrochanteric fractures (Arbeitsgemeinschaft für Osteosynthesefragen classification 31-A1) of the femur by using optimized finite element analysis. Biomechanical study. Computed tomography images of patients' right femurs were processed with Mimics. Afterwards a solid femur model was created with SolidWorks 2015 and transferred to ANSYS Workbench 16.0 for response surface optimization analysis which was carried out according to anterior-posterior (-10°0) and posterior-anterior directions of the femur neck significantly increased these stresses. The most suitable position of the proximal lag screw was confirmed as the middle of the femoral neck by using optimized finite element analysis.

    Full Text Available 【Abstract】 Objective: Fractures of the femur are the most incapacitating fractures. For children aged 6-14 years, there is no clear consensus as to the preferred treatment. The conventional treatment of traction and cast-ing is no longer recommended. We report our experience in titanium elastic nailing for treatment of paediatric femoral diaphyseal fractures. Methods: Thirty patients in the age group of 6-16 years with displaced diaphyseal femoral fractures were sta-bilized with titanium elastic nails. Patients were followed up clinically and radiologically for a minimum period of 1 year. The final results were evaluated using Flynn’s criteria. Tech-nical difficulties and complications associated with the pro-cedure were also analysed. Results: Overall results were excellent in 20 cases and satisfactory in 10 cases. No patient had poor result. The average hospital stay was 9 days. All the fractures healed with an average time to union of 6.86 weeks. The most com-mon complication encountered was soft tissue irritation at the nail entry site seen in 6 cases. Clinically, lengthening was noticed in 4 cases, while no patient had shortening. Malalignment was seen in only 6 cases. Perioperative diffi-culties encountered were failure of closed reduction seen in 6 cases and corkscrewing of nails in one case. Conclusion: Titanium elastic nails are a relatively easy to use, minimally invasive, physeal-protective implant sys-tem with high rate of good and excellent outcomes in chil-dren aged 6-16 years. Technical pitfalls can be eliminated by adhering to the basic principles. Key words: Titanium; Nails; Fractures, bone; Femur; Paediatrics

    Dynamisation is a simple method for treating femoral shaft fractures (FSFs) in patients with delayed healing after intramedullary nailing. However, only around half of patients with a slow-healing FSF have been successfully treated with this strategy. Although it is thought that dynamisation with a screw preserved in the dynamic locking hole improves treatment outcome in these patients, to date, no studies have demonstrated empirical evidence supporting this technique. In this study, we investigated the effects of dynamisation with and without rotation and length control as well as timing of dynamisation on treatment outcomes in FSF patients with delayed healing. Thirty-nine consecutive acute FSF patients with static locking intramedullary nails who subsequently underwent dynamisation were recruited between January 2000 and June 2011. The indication for dynamisation was the presence of gap caused by bone absorption or over-traction at the fracture site when the locking screws were placed. Age, gender, dynamisation method, fracture classification, duration from nail insertion to dynamisation (i.e., timing of dynamisation) and dynamisation outcome were included in the statistical analysis. Patients whose nail was dynamised with a screw preserved in the dynamic locking hole had a significantly higher successful bone union rate (14/15 vs. 14/24, p=0.028) compared with those with all screws removed from one end of the nail. The patients treated in 10-24 weeks had a significantly increased chance of bone union than those treated after 24 weeks (p=0.027). A significantly higher bone union rate (p=0.036) was observed in 10-24 weeks (83.3%) than after 24 weeks (33.3%) in the group of dynamisation with all screws removed from one end of the nail. No statistical difference in bone union success rate was found between patients at 10-24 weeks and after 24 weeks in the group of dynamisation with a screw preserved in the dynamic locking hole. There were no significant differences

    Intramedullary fixation is the treatment of choice for diaphyseal fractures of the femur and tibia. Locking the implant can sometimes be cumbersome and time consuming. In our institution, fractures with axial and rotational stability are treated with intramedullary nailing without interlocking. All consecutive patients presented in the University Medical Center Utrecht from October 2003 to August 2009 with acute traumatic diaphyseal fractures of the tibia or femur that were considered axial and rotational stable were included. They underwent internal fixation using intramedullary nails without interlocking. Patient records were evaluated for duration of surgery, perioperative complications, consolidation time and re-operations. Twenty-nine long bone fractures were treated in 27 patients: 20 men and 7 women, with an average age of 28.9 years (range 15.6-54.4). There were 12 femoral fractures and 17 tibial fractures. Sixteen fractures were closed and 13 were open (10 Gustilo 1, 3 Gustilo 2). The mean operating time was 43 min (range 18-68 min) for tibial fractures and 55 min (range 47-150 min) for femoral fractures. Postoperative complications occurred in six patients. Two patients (three fractures) were lost to follow-up. Healing occurred in 25 of the 26 remaining fractures (96 %) without additional interventions. One tibia was secondarily converted to a standard locked nail because of axial and rotational instability. All patients returned to their pre-injury level of activity. The use of intramedullary nailing without interlocking is associated with minimal complications in selected fractures. The advantages include a short operating time and the simplicity of its application.

    Full Text Available Abstract Introduction Femoral subtrochanteric fractures are commonly treated using intramedullary devices. Failure of the implant and subsequent nonunion is still an issue, however, and limited evidence exists regarding the most appropriate treatment. Case presentation We report the case of an 80-year-old Caucasian woman with a subtrochanteric fracture originally treated using a trochanteric gamma nail which failed, resulting in a nonunion and fracture of its proximal end. The nonunion was revised with the removal of the broken trochanteric gamma nail, application of a condylar blade plate, ipsilateral Reamer/Irrigator/Aspirator autografting, recombinant human bone morphogenetic protein-7 and injectable hydroxyapatite cement. The fracture united fully at ten months following revision surgery, with no signs of femoral head avascular necrosis at 18-month follow-up. Conclusion The essential requirements for success when revising a nonunited fracture are to provide anatomical reduction, mechanical stability, bone defect augmentation and biological stimulation to achieve healing. Current advances in molecular biology, such as recombinant human bone morphogenetic protein-7, and biotechnology such as the Reamer/Irrigator/Aspirator system and hydroxyapatite injectable cement can improve patient outcomes over the use of our traditional revision techniques.

    People with dementia have poor mobility and discharge outcomes following hip fractures. The purpose of this study was to evaluate the clinical and radiological results of internal fixation of undisplaced femur neck fractures (Garden types 1 and 2) by proximal femoral nail antirotation (PFNA) in dementia patients. We studied retrospectively 19 patients with undisplaced femur neck fracture. All patients were over 70 years of age, walked independently with a cane or crutches and suffered moderate-to-severe dementia. Patients were treated with PFNA and followed-up for more than 2 years. Revision, loss of fixation, complications, and walking ability outcomes were measured. In walking-ability evaluation, patients showed an average decrease of just 0.2 points at the final follow-up. Walking ability was evaluated from before injury to 4 weeks after surgery and decreased by less than 0.5 points. Radiological bone union was achieved in 17 cases; the average time to bone union was 4.14 months (range, 2.5-7 months). Complications included non-union in two cases and femoral head avascular necrosis in one case of non-union. We found that for patients with osteoporotic bone tissues in their femoral heads or patients (e.g., those suffering dementia) for whom cooperating with medical workers for postoperative walking control or rehabilitation exercises is difficult, implanting a mechanically stable spiral blade for fixation of femoral neck fractures could facilitate walking after surgery.

    To show that patients with intertrochanteric fractures treated with a proximal femoral nail have a better postoperative course than those treated with a DHS plate (dynamic hip screw). Patients with a Boyd & Griffin type II intertrochanteric fracture were randomly divided into two groups: a group of patients treated with a PFN and another one treated with a DHS plate. All patients were assessed at 2, 4, 8 and 16 weeks using the Harris scale and the visual analog scale pre- and postoperatively, as well as the operative time, incision size, intraoperative bleeding, onset of partial and/or total weight bearing, healing time, time to attain prior physical activity level, and radiographic result. 32 patients met our criteria. The variables that had a significant reduction were: incision, operative time, postoperative pain according to the visual analog scale, onset of mobility, partial weight bearing and pain at 2 weeks. The proximal femoral nail has better short-term outcomes than the DHS plate; however, in the medium term both implants have the same outcomes.

    Limb lengthening for congenital femoral deficiency (CFD) with or without fibular hemimelia can be performed with both external and internal devices. The purpose of this study is to compare clinical outcomes of femoral lengthening utilizing monolateral external fixation versus a magnetically motorized intramedullary nail in patients with CFD with or without fibular hemimelia. This retrospective review included 62 patients with femoral lengthening, 32 patients had monolateral external fixation (group A), 30 patients had internal lengthening nail (group B). Mean age in years was 9.4±3.8 and 15.4±4.9 for groups A and B, respectively. Mean follow-up in years was 4.47±2.7 and 1.86±0.7 years for groups A and B, respectively. Mean lengthening achieved was 5.6±1.7 and 4.8±1.4 cm for group A and group B, respectively (P=0.052). Mean distraction index was 0.7±0.2 mm/d for group A and 0.7±0.2 mm/d for the group B (P=0.99). Mean consolidation index for group A was 29.3±12.7 and 34.8±11.2 d/cm for group B (P=0.08). Mean arc of motion before surgery and at final follow-up were similar between groups (P=0.35). Group A had significantly less range of motion at the end of distraction (P=0.0007) and at consolidation (P<0.0001). Both groups had similar rates of obstacles and complications. A significant difference between groups was found in the total problems (P<0.001) specifically with pin site/superficial infection (P<0.0001). The intramedullary nail had superior range of motion during the lengthening phase and at consolidation and an overall lower problem complication rate, while maintaining similar distraction and healing indices to monolateral external fixation. Internal lengthening nails represent a significant advance in technology for CFD lengthening.

    Femoral supracondylar nonunions in elderly patients are uncommon. To date, there is no convincing technique for managing this condition. When the nonunion is associated with severe osteoporosis, treatment becomes even more complicated. We developed a modified retrograde-locked nailing technique to treat this complex lesion. Twenty-four aseptic femoral supracondylar nonunions with severe osteopenia in 24 elderly patients (aged ≥65 years) were treated. A retrograde femoral-locked nail was inserted in the dynamic mode. Next, the medial ½ to 2/3 marrow cavity in the nonunion site was filled with bone cement, and the lateral 1/3 to ½ marrow cavity received a cancellous bone graft with or without a bone graft substitute. A cylindrical brace was applied for 3 weeks postoperation. Early ambulation with a walker or wheelchair was encouraged. Twenty patients were followed up for an average period of 2.5 years (range, 1.1-4.5 years), and 18 nonunions healed. The union rate was 90.0% with an average union period of 4.9 months (range, 4-7 months). No deep infection or malunion was found. The two patients with persistent nonunions were advised to use a walker whenever necessary. The satisfactory rate for knee function improved from 0% preoperatively to 80.0% at the latest follow-up. The described technique may concomitantly provide sufficient stability and initiate osteogenic potential, thus facilitating bone union. This technique is simple with a low complication rate and thus should be considered as a useful alternative for treating this complex lesion.

    Anatomic fit of intramedullary nails was suggested by previous studies to improve significantly when the nail radius of curvature (ROC) is closer to the average femoral anatomy. However, no attempt has been made to investigate the impact of different ROC designs on the nail insertion process. Therefore, this biomechanical study quantitatively compared the ease of insertion between femoral intramedullary nails with a 1.0-m and a 1.5-m bow radius. Long TFN-ADVANCED™ (TFNA, 1.0 m ROC) and Proximal Femoral Nail Antirotation nails (PFNA, 1.5 m ROC) were implanted pairwise into seven paired cadaver femora. All bones were reamed 1.5 mm larger than the nail diameter. Using a material testing machine, intramedullary nailing was then performed stepwise with 20-mm steps and a 10-mm/s insertion rate, and force was measured. The nail deformation caused by the insertion was assessed through 3D computer models built from pre- and post-nailing CT scans. The ease of insertion between TFNA and PFNA nails was quantified in terms of insertion force, insertion energy and nail deformation. There was no significant difference in the peak force generated during nailing between TFNA and PFNA nails (P = 0.731). However, the force measured at the end of insertion (P = 0.002) was significantly smaller in TFNA nails compared to PFNA nails. After implantation, TFNA nails showed significantly smaller deformation when compared to PFNA nails (P = 0.005, both ends aligned). Furthermore, less energy was required to insert TFNA nails; however, the difference was not significant (P = 0.25). Compared to PFNA nails, a significant decrease in insertion force and nail deformation was found at the end of insertion for TFNA nails. Results suggest that TFNA having a 1.0-m ROC is easier to insert for the set of femora used in this study compared to PFNA with a 1.5-m ROC.

    Full Text Available Abstract Background Elastic Stable intramedullary Nailing (ESIN of dislocated diaphyseal femur fractures has become an accepted method for the treatment in children and adolescents with open physis. Studies focused on complications of this technique showed problems regarding stability, usually in complex fracture types such as spiral fractures and in older children weighing > 40 kg. Biomechanical in vitro testing was performed to evaluate the stability of simulated spiral femoral fractures after retrograde flexible titanium intramedullary nail fixation with and without End caps. Methods Eight synthetic adolescent-size femoral bone models (Sawbones® with a medullar canal of 10 mm and a spiral fracture of 100 mm length identically sawn by the manufacturer were used for each group. Both groups underwent retrograde fixation with two 3.5 mm Titanium C-shaped nails inserted from medial and lateral entry portals. In the End Cap group the ends of the nails of the eight specimens were covered with End Caps (Synthes Company, Oberdorf, Switzerland at the distal entry. Results Beside posterior-anterior stress (4.11 Nm/mm vs. 1.78 Nm/mm, p Conclusion In this biomechanical study the use of End Caps did not improve the stability of the intramedullary flexible nail osteosynthesis.

    Full Text Available Abstract Background The dynamic compression screw is a plate and screws implant used to treat fractures of the distal femur. The Biomet Matthews Nail is a new retrograde intramedullary nail designed as an alternative surgical option to treat these fractures. The objective of this study was to assess the comparative endurance of both devices. Method The dynamic compression screw (DCS and Biomet Matthews Nail (BMN were implanted into composite femurs, which were subsequently cyclically loaded using a materials testing machine. Simulated fractures were applied to each femur prior to the application of load. Either a Y type fracture or a transverse osteotomy was prepared on each composite femur using a jig to enable consistent positioning of cuts. Results The Biomet Matthews Nail demonstrated a greater endurance limit load over the dynamic compression screw in both fracture configurations. Conclusion The distal locking screws pass through the Biomet Matthews Nail in a unique "cruciate" orientation. This allows for greater purchase in the bone of the femoral condyle and potentially improves the stability of the fracture fixation. As these fractures are usually in weak osteoporotic bone, the Biomet Matthews Nail represents a favourable surgical option in these patients.

Our objective was close reduction of these difficult fractures by a simple but effective method using Schanz screws for manipulating fracture fragments on a radiolucent table.Materials & Methods: In this prospective study, 30 patients whose femoral shaft fractures required reduction were operated on a radiolucent table in the lateral position and their fractures reduced closed by Schanz pins and fixed with IM Rod. The patients were followed-up 1 year. Results: We obtained reduction in 93% of patients. Average time of reduction in the first 48 hours was 9.23minutes and after 48 hours it was 19.7minutes (p<0.05. Also time to reduction was dependent on amount of preoperative traction .When the amount of preoperative traction was 5kg, that time was 19.16minutes but in maximal amount of traction it was 10.29minutes. Time to reduction also was shorter in Winquist-Hansen type III and IV fractures than in type I and II fractures. There was 13% valgus deformity (5-10 o, 33% external malrotation (5-15 o and 37% shortening (up to 1-3 cm. But we had no infection and no need for blood transfusion or bone grafting.Conclusion: Schanz screws provide a very effective method for close reduction of femoral shaft fractures. Complications of this method are the same or even in some parts are less than other close reduction methods. The method is more successful if performed in the first 48 hours, or if the weight of preoperative skeletal traction is near to the maximum (15% of body weight.

    Full Text Available Abstract Objective To evaluate, through biomechanical testing, the resistance to and energy required for the occurrence of proximal femoral fracture in synthetic bone after removal of a proximal femoral nail model (PFN, comparing the results obtained with a reinforcement technique using polymethylmethacrylate (PMMA. Methods Fifteen synthetic bones were used: five units for the control group (CG, five for the test group without reinforcement (TGNR, and five for the test group with reinforcement (TGR. The biomechanical analysis was performed simulating a fall on the trochanter using a servo-hydraulic machine. In the GC, the assay was performed with the PFN intact. In the TGNR and TGR groups, a model of PFN was introduced and the tests were performed in the TGNR, after simple removal of the synthesis material, and in the TGR, after removal of the same PFN model and filling of the cavity in the femoral neck with PMMA. Results All groups presented a basicervical fracture. The CG presented a mean of 1427.39 Newtons (N of maximum load and 10.14 Joules (J of energy for the occurrence of the fracture. The TGNR and TGR presented 892.14 N and 1477.80 N of maximum load, and 6.71 J and 11.99 J of energy, respectively. According to the Kruskal-Wallis ANOVA, there was a significant difference in the maximum load (p = 0.009 and energy (p = 0.007 between these groups. Conclusion The simple removal of a PFN in synthetic bone showed a significant reduction of the maximum load and energy for the occurrence of fracture, which were re-established with a reinforcement technique using PMMA.

    Elastic stable intramedullary nailing (ESIN) may be complicated by the loss of reduction following push out of the nails at the entry site in unstable femoral and tibial fractures, especially in older and heavier children and following technical failures. An end cap system addressing this complication was evaluated clinically. In a retrospective case series, 49 femoral and five tibial fractures in 54 pediatric patients treated by ESIN and end caps were documented in two European tertiary centers. End caps were used to interlock standard ESIN nails. The results were evaluated regarding difficulties in the placement and removal of the end cap system, fracture stability and healing, and return to normal activities by analyzing patient charts and X-rays. Fifty-three of 54 fractures were stabilized sufficiently with ESIN and end caps. Loss of reduction was observed in one patient, requiring additional surgery. Six complications were observed, five of which were not related to end caps. There were no significant leg length differences or varus/valgus deformities. A rotational difference of >10°-20° was found in one patient. Removal of the end caps and nails was rated as simple and uncomplicated in 35/37 cases. End caps avoided postoperative instability in the majority of pediatric patients with lower limb shaft fractures, even in heavier, older patients and those with instable fracture types. End caps, however, will not compensate for operative technical insufficiency concerning reduction or nail placement. To maximize the stability of ESIN-instrumented unstable fractures, end caps require properly placed nails.

    Soft tissue injury occurs when using a piriformis portal for femoral nailing. Standard trochanteric portals also can injure the gluteus medius and external rotator tendons, which may be a source of hip pain after nailing. On the lateral facet of the greater trochanter, a “bald spot” may exist that is devoid of tendon insertion. This may be a potential portal for intramedullary nail insertion. We defined the dimensions and location of this region. Cadaveric specimens were dissected to expose the tendon insertions on the greater trochanter. A computer navigation system was used with a stylus and bone morphing to determine the tendon insertions and bald spot anatomy. The greater trochanteric bald spot is covered by the subgluteus medius bursa and has no tendon insertions. Its center lies 11 mm distal to the tip of the greater trochanter and 5 mm anterior to the midline. The shape is ellipsoid with a diameter of 21 mm. This region is large enough to accommodate the size of most nailing system reamers without tendon footprint infringement. Use of this modified entry site may reduce soft tissue injury with nailing procedures and minimize subsequent hip pain. PMID:18347886

    Stress fractures could be classified as fatigue fractures and insufficiency fractures (IF). Fatigue fractures occur when abnormal mechanical stress is applied to a normal bone, on the other hand insufficiency fractures occur when normal to moderate pressure is applied to a bone that has decreased resistance (Daffner and Pavlov in Am J Radiol 159:242-245, 1992). IF have been observed mainly in patients with postmenopausal osteoporosis, and are becoming more common with the increase of elderly population (Daffner and Pavlov in Am J Radiol 159:242-245, 1992). Other systemic and metabolic conditions that can result in osteopenia and IF include osteomalacia, hyperparathyroidism, hyperthyroidism, rheumatoid arthritis, fluoride treatment, diabetes mellitus, fibrous dysplasia, Paget's disease, irradiation and mechanical factors (Daffner and Pavlov in Am J Radiol 159:242-245, 1992; Soubrier et al. in Joint Bone Spine 70:209-218, 2003; Epps et al. in Am J Orthop 33:457-460, 2004; Austin and Chrissos in Orthopedics 28:795-797, 2005). In this case report, the authors present an osteoporotic woman who developed bilateral insufficiency fracture of the femoral shaft after longstanding steroid, thyroxine replacement and alendronate therapy due to partial empty sella syndrome and osteoporosis, resulting in the treatment of the fracture by inflatable intramedullary nailing.

    Elastic Stable intramedullary Nailing (ESIN) of dislocated diaphyseal femur fractures has become an accepted method for the treatment in children and adolescents with open physis. Studies focused on complications of this technique showed problems regarding stability, usually in complex fracture types such as spiral fractures and in older children weighing > 40 kg. Biomechanical in vitro testing was performed to evaluate the stability of simulated spiral femoral fractures after retrograde flexible titanium intramedullary nail fixation with and without End caps. Eight synthetic adolescent-size femoral bone models (Sawbones® with a medullar canal of 10 mm and a spiral fracture of 100 mm length identically sawn by the manufacturer) were used for each group. Both groups underwent retrograde fixation with two 3.5 mm Titanium C-shaped nails inserted from medial and lateral entry portals. In the End Cap group the ends of the nails of the eight specimens were covered with End Caps (Synthes Company, Oberdorf, Switzerland) at the distal entry. Beside posterior-anterior stress (4.11 Nm/mm vs. 1.78 Nm/mm, p Caps demonstrated no higher stability in 4-point bending compared to the group without End Caps (anterior-posterior bending 0.27 Nm/mm vs. 0.77 Nm/mm, p difference (0.37 Nm/° vs. 0.32 Nm/°, p = 0.13 and 1.29 mm vs. 2.18 mm, p = 0.20, respectively) compared to the "classic" 2-C-shaped osteosynthesis without End Caps. In this biomechanical study the use of End Caps did not improve the stability of the intramedullary flexible nail osteosynthesis.

    The purpose of this study was to compare the clinical outcomes of elderly patients undergoing surgery for treatment of unstable trochanteric fractures receiving either proximal femoral nails anti-rotation-Asia (PFNA-IIs) or InterTan nails (ITs). Between January 1, 2012, and June 31, 2015, 168 elderly patients with unstable intertrochanteric femur fractures enrolled in this study. The only intervention was ITs or PFNA-IIs of the unstable trochanteric femur fractures. Follow-up was at 1, 3, 6, and 12 months postoperatively and yearly thereafter. Intraoperative variables and postoperative complications were compared between the two groups. Eight patients died, six were too infirmed for follow-up, and seven were lost during follow-up, leaving 147 patients meeting the criteria were evaluated at a mean follow-up of 20 months (range 16-26 months). Significant differences were observed between the two groups regarding local complications (IT, n = 10 vs. PFNA-II, n = 20), varus collapse of the head/neck or femoral shaft fractures at the tip of the nail (IT, n = 1 vs. PFNA-II, n = 8), femoral neck shortening (IT, 4.4 ± 1.1 mm vs. PFNA-II, 7.4 ± 2.4 mm), fracture healing time (IT, 14.7 ± 2.1 weeks vs. PFNA-II, 15.7 ± 2.4 weeks), femoral shaft fractures (IT, n = 0 vs. PFNA-II, n = 4), rotational loss of reduction (IT, n = 0 vs. PFNA-II, n = 9), lateral cortex fractures of the proximal femur or lateral greater trochanter fractures (IT, n = 8 vs. PFNA-II, n = 1), operative time (IT, 71.9 ± 6.8 min vs. PFNA-II, 52.3 ± 4.0 min), intraoperative blood loss (IT, 190.6 ± 6.0 mL vs. PFNA-II, 180.9 ± 10.8 mL), fluoroscopy time (IT, 5.0 ± 0.48 min vs. PFNA-II, 2.8 ± 0.33 min), hospital stay (IT, 9.65 ± 0.95 days vs. PFNA-II, 8.58 ± 0.93 days), cut-out (IT, n = 0 vs. PFNA-II, n = 6), and tip-apex distance (IT, 26.7 ± 0.91 mm vs. PFNA-II, 23.2 ± 1.22 mm). No significant differences existed for the other observation indexes (p > 0.05). The IT nail may have more advantage for

    Full Text Available Abstract Background The most common mechanical failure in the internal fixation of trochanteric hip fractures is the cut-out of the sliding screw through the femoral head. Several factors that influence this complication have been suggested, but there is no consensus as to the relative importance of each factor. The purpose of this study was to analyse the cut-out complication with respect to the following variables: patients’ age, fracture type, fracture reduction, implant positioning and implant design. Methods 3066 consecutive patients were treated for trochanteric fractures with Gamma Nails between 1990 and 2002 at the Centre de Traumatologie et de l`Orthopedie (CTO, Strasbourg, France. Cut-out complications were identified by reviewing all available case notes and radiographs. Subsequently, the data were analysed by a single reviewer (AJB with focus on the studied factors. Results Seventy-one cut-out complications were found (2.3% of the 3066 trochanteric fractures. Cut-out failure associated with avascular head necrosis, pathologic fracture, deep infection or secondary to prior failure of other implants were excluded from the study (14 cases. The remaining 57 cases (1.85 %, median age 82.6, 79% females were believed to have a biomechanical explanation for the cut-out failure. 41 patients had a basicervical or complex fracture type. A majority of cut-outs (43 hips, 75% had a combination of the critical factors studied; non-anatomical reduction, non-optimal lag screw position and the characteristic fracture pattern found. Conclusions The primary cut-out rate of 1.85% was low compared with the literature. A typical cut-out complication in our study is represented by an unstable fracture involving the trochanteric and cervical regions or the combination of both, non-anatomical reduction and non-optimal screw position. Surgeons confronted with proximal femoral fractures should carefully scrutinize preoperative radiographs to assess the

    Intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. Dynamic Hip Screw (DHS) is still considered the gold standard for treating intertrochanteric fractures by many. Not many studies compare the DHS with Proximal femoral nail (PFN), in Type II intertrochanteric fractures (Boyd and Griffin classification). This study was done to compare the functional and radiological outcome of PFN with DHS in treatment of Type II intertrochanteric fractures. From October 2012 to March 2015, a prospective comparative study was done where 30 alternative cases of type II intertrochanteric fractures of hip were operated using PFN or DHS. Intraoperative complications were noted. Functional outcome was assessed using Harris Hip Score and radiological findings were compared at 3, 6, and 12 months postoperatively. The average age of the patients was 60 years. In our series we found that patients with DHS had increased intraoperative blood loss (159ml), longer duration of surgery (105min), and required longer time for mobilization while patients who underwent PFN had lower intraoperative blood loss (73ml), shorter duration of surgery (91min), and allowed early mobilization. The average limb shortening in DHS group was 9.33 mm as compared with PFN group which was only 4.72 mm. The patients treated with PFN started early ambulation as they had better Harris Hip Score in the early post-op period. At the end of 12th month, there was not much difference in the functional outcome between the two groups. PFN is better than DHS in type II intertrochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight bearing and mobilization, reduced hospital stay, decreased risk of infection and decreased complications.

    Full Text Available Background. The purpose of this meta-analysis was to find out whether the proximal femoral nail was better than the dynamic hip screw in the treatment of trochanteric fractures with respect to operation time, blood transfusion, hospital stay, wound complications, number of reoperation, and mortality rate. Methods. All randomized controlled trials comparing proximal femoral nail and dynamic hip screw in the treatment of trochanteric fractures were included. Articles and conference data were extracted by two authors independently. Data was analyzed using RevMan 5.1 version. Eight trials involving 1348 fractures were retrieved. Results. Compared with DHS fixation, PFN fixation had similar operation time (95% CI: −15.28–2.40, P=0.15. Blood loss and transfusion during perioperative time were also comparable between the two fixations (95% CI: −301.39–28.11, P=0.10; 95% CI: −356.02–107.20, P=0.29, resp.. Outcomes of hospital stay (95% CI: −0.62–1.01, P=0.64, wound complication (95% CI: 0.66–1.67, P=0.82, mortality (95% CI: 0.83–1.30, P=0.72, and reoperation (95% CI: 0.61–1.54, P=0.90 were all similar between the two groups. Conclusion. PFN fixation shows the same effectiveness as DHS fixation in the parameters measured.

    Salter Harris fractures of the distal femur can lead to growth disturbance with resulting leg length inequality and knee deformity. We have looked at a case series (3) of patients who presented with a distal femur flexion malunion and shortening treated with a distal femoral osteotomy and plating and a proximal femoral osteotomy with a magnetic internal lengthening nail. Does a two-level osteotomy and internal fixation approach provide a reliable result both radiographically and functionally? The average knee extension loss was 12°, LLD 47 mm, PDFA 65°, MAD 2 mm. The patients were treated with an acute, posterior, opening wedge osteotomy of the distal femur stabilized with a lateral plate and screws and grafted with cancellous chips and putty. A second osteotomy was made proximally in the femur percutaneously, and the internal lengthening nail was inserted. Lengthening was done at approximately 1 mm/day. The average extension gain was 12°; amount of lengthening at the proximal site was 40 mm, LLD was 3 mm. The average PDFA was 81°, and MAD 3 mm. There were no complications. Functional results were excellent. Bone healing index was 24 days/cm. The average distance from the distal osteotomy to the joint line was 57 mm. The technique of two-level femur osteotomy stabilized with a plate and lengthening nail yielded excellent results with acceptable correction of deformity, full knee extension, and improved function. There were no complications including implant failure, infection, need for blood transfusion, knee stiffness, nonunion, compartment syndrome, or malunion.

    The purpose of this study was to compare the results of pedobarographic gait analysis between the patients treated by proximal femoral nail or bipolar partial hemiarthroplasty due to intertrochanteric fractures. Thirty-seven patients with a minimum 1-year follow-up who had been operated for intertrochanteric fractures were evaluated clinically, radiologically and with pedobarographic gait analysis. Proximal femoral nail had been performed to 21 patients (group A), whilst 16 patients had been operated by partial bipolar hemiarthroplasty (group B). Pedobarographic analysis was performed by measuring plantar pressure, force and contact area values in both static and dynamic manner. Pedobarographic results of operated limb were compared among groups. Same data's also were compared between operated and uninjured limbs in each group to determine any asymmetry on weight-bearing. Average follow-up period in group A and group B was 36 (12-56) and 30 (12-48) months, respectively. There were no statistically significant differences among groups in terms of age, gender, body mass index, type and side of fracture, follow-up period, leg length discrepancy and postoperative hip scores. When the pedobarographic results of operated limb were compared, group B showed much more plantar force and pressure values than group A, on both static and dynamic evaluations. If the evaluation was taken into consideration to comparison of pedobarographic results between operated and uninjured limbs in each group, we found asymmetry in static load bearing, caused by higher load on uninjured limb in both groups. However, there was no statistically significant asymmetry between operated and uninjured limbs in respect to dynamic pedobarographic parameters for patients in group A. On the contrary, operated limbs in group B exposed much more plantar force and pressure values than uninjured limbs, which indicated asymmetric weight-bearing on dynamic evaluation.

    To facilitate simple and safe manipulation during proximal femoral nail antirotation (PFNA) operation, we studied the range of safe implantation angle of the helical blade of the PFNA system by using a digital-based three-dimensional reconstruction model of CT images. Thirty-five healthy volunteers were recruited. Original multilayer helical CT scan data of the left femur were collected and imported into Mimics software. Anatomic features of the femur, including the safe implantation angle, anterior and posterior angle, were measured. Differences in each angle between male and female subjects were compared using Student's t test, and the determinants of each angle were analyzed by linear regression. The mean safe implantation angle was 30.09° ± 4.73°, the mean anterior angle was 15.82° ± 2.07°, and the mean posterior angle was 14.27° ± 3.19°. All the three angles were greater in males than females (P angle and the diameter of the femoral neck and head were linearly correlated with the safe implantation angle, the anterior and posterior angle, respectively. Femoral neck diameter was a significant determinant of the safe implantation angle and posterior angle, respectively. Moreover, femoral neck diameter and femoral head diameter were significant determinants of the anterior angle. The study has introduced and delineated a novel parameter, the safe implantation angle, for FPNA surgery, which may help orthopedic surgeons in deciding a safe range of PFNA operation and improve the accuracy of PFNA helical blade implantation.

    Although the method has been used widely, one of the greatest challenges for intramedullary nailing is to position the distal locking screw. A new technology, the electromagnetic navigation system, is a radiation-free way to locate the position of the drill bit and provide 3-dimensional real-time feedback of location and orientation of the drill bit relative to the locking holes. The purpose of our study was to evaluate the reliability and efficiency of the free-hand technique compared to the new electromagnetic navigation system. Fifty-four patients with femoral fracture who needed treatment with intramedullary nails were divided into 2 groups. One group including 26 patients underwent distal locking using the standard free-hand method, whereas the electromagnetic navigation system was used with the other 29 patients. Intraoperative fluoroscopy exposure times, screw insertion times, and healing times were recorded; these parameters were used for comparison between the 2 groups. There were 17 males and 9 females who had femoral intramedullary nails using the free-hand technique, whereas 21 males and 8 females received intramedullary nails using the electromagnetic navigation system. The mean time of distal locking was 19.5 ± 6.0 minutes in the free-hand (FH) group, whereas the time was 6.1 ± 1.4 minutes in the electromagnetic (ET) group. The exposure time for the FH group was 26.8 ± 13.3 seconds and 2.2 ± 1.1 seconds for the ET group. Healing time proved to be comparable in the FH and ET groups (16.4 ± 3.7 weeks vs 15.1 ± 2.8 weeks). Under the premise of achieving the same effect, the electromagnetic navigation system has the advantage of less distal locking time and less radiation dose.

    The piriformis fossa is the ideal portal of entry for antegrade interlocking nailing. Localizing this portal can be difficult and its eccentricity leads to complications. This prospective comparative study was designed to compare an innovative way to obtain the ideal portal from inside the medullary canal in cases of plate failure and compare it to the classic antegrade portal. It included 41 cases (19 antegrade and 22 retrograde). The retrograde portal was significantly better in terms of entry time, radiation time, blood-loss, and wound length. The proper portal was rapidly and easily achieved in all retrograde cases without complications; while four in antegrade cases had complications. Minimum follow-up was 2 years. Level of evidence III.

IM nailing protects the soft-tissue envelope due to its minimally invasive approach and closed reduction techniques better than distal femoral locked plating. The purpose of this study was to evaluate and compare outcome of distal femur fracture stabilization using RN or LISS techniques. Materials and Methods: In a retrospective study from 2003 to 2008, we analyzed 115 patients with distal femur fracture who had been treated by retrograde IM nailing (59 patients or LISS plating (56 patients. In the two cohort groups, mean age was 54 years (17-89 years. Mechanism of injury was high energy impact in 57% (53% RN, 67% LISS and low-energy injury in 43% (47% RN, 33% LISS, respectively. Fractures were classified according to AO classification: there were 52 type A fractures (RN 31, LISS 21 and 63 type C fractures (RN 28, LISS 35; 32% (RN and 56% (LISS were open and 68% (RN and 44% (LISS were closed fractures, respectively. Functional and radiological outcome was assessed. Results: Clinical and radiographic evaluation demonstrated osseous healing within 6 months following RN and following LISS plating in over 90% of patients. However, no statistically significant differences were found for the parameters time to osseous healing, rate of nonunion, and postoperative complications. The following complications were treated: hematoma formation (one patient RN and three patients LISS, superficial infection (one patient RN and three patients LISS, deep infection (2 patients LISS. Additional secondary bone grafting for successful healing 3 months after the primary operation was required in four patients in the RN (7% of patients and six in the LISS group (10% of patients

    Full Text Available Non-union is a well recognized complication of femoral neck fractures. The decision whether to attempt fracture fixation or to resort to hip replacement is particularly difficult in patients in the borderline age group in whom complex attempts at gaining union may fail and later present a difficult revision. On the other hand the patient may be young enough that arthroplasty best be avoided . Besides, presence of ipsilateral femoral shaft fracture with delayed union in addition to the femoral neck non-union will pose major problems at operation. We share our experience in treating a femoral neck fracture non-union with ipsilateral femoral shaft delayed union in the shaft and in the distal femur in a fifty years old patient. The fracture was treated with an angle blade plate and supracondylar nail supplemented with a free vascularised fibular bone grafting and autologous cancellous graft. There was radiological union at fourth month. At sixth months, the patient was free of pain and able to walk without support. Thus, we would like to suggest that vascularised fibula bone grafting with supracondylar nailing is a viable option for this pattern of fracture.

    Reconstruction for concurrent infection of an ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) is a challenge. We report a 2-stage reconstruction of a THA for chronic infection of both the THA and TKA with severe femoral bone loss secondary to interprosthetic fractures. The reconstruction involved using a custom-made, temporary, antibiotic-impregnated PROSTALAC spacer mated with an intramedullary nail. The acetabulum was then exposed and the necrotic cartilage was removed and curetted. The acetabulum was reamed to accept a PROSTALAC acetabular shell. The shell was cemented into the acetabulum with antibiotic cement. The custom-made spacer was then inserted distally first into the tibia. The distal end of the intramedullary nail was interlocked with a bicortical bolt to minimise nail rotation. Antibiotic-impregnated cement was moulded around the nail and spacer. The proximal end of the spacer was then reduced into the acetabular socket, and the joint was irrigated and the wound closed. A customised abduction brace was fitted, and partial weight bearing was allowed. Sufficient leg length, soft-tissue tension, and range of hip motion were restored, and a total femur and constrained liner was re-implanted 4 months later. Mating of an intramedullary nail with a PROSTALAC spacer is a viable reconstructive option.

    To analyze the natural exit of the wire guides in major trochanter through retrograde femoral approach, in cadaver specimens. 100 femurs had been perforated between the femoral condyles, at 1.2 cm of the intercondylar region. A 3-mm straight wire guide was introduced, through retrograde approach, until the proximal extremity of femur was reached. Femurs were assessed for posterosuperior and anterosuperior portions of major trochanter, pear-shaped cavity, and upper median line between the head-neck and the major trochanter. in 62%, the straight wire guides exited at the anterior surface of major trochanter. In the pear-shaped cavity, the median distance found was 1.0 cm and the interquartile range was 0.5 cm, initially expressing, in relation to pear-shaped cavity, better accuracy. the central axis of the medullar canal, at coronal plane, projected better accuracy in the region of the pear-shaped cavity.

    Internal fixation is a therapeutic mainstay for treatment of undisplaced femoral neck fractures and fractures without posterior comminution. The best treatment for unstable and comminuted fractures, however, remains controversial, especially in older patients. The present study was designed to assess the utility of the Intertan Nail® (IT) for stabilization of comminuted Pauwels type III fractures compared to dynamic hips screw (DHS). Randomized on the basis of bone mineral density, 32 human femurs were assigned to four groups. Pauwels type III fractures were osteomized with a custom-made saw guide. In 16 specimens the posteromedial support was removed and all femurs were instrumented with an IT or a DHS. All constructs were tested with nondestructive axial loading to 700N, cyclical compression to 1,400N (10,000 cycles), and loading to failure. Outcome measures included number of survived cycles, mechanical stiffness, head displacement and load to failure. Postoperative mechanical stiffness and stiffness after cyclical loading were significantly reduced in all constructs regardless of the presence of a comminution defect (p = 0.02). Specimens stabilized with the IT had a lower construct displacement (IT, 8.5 ± 0.5 mm vs. DHS, 14.5 ± 2.2 mm; p = 0.007) and sustained higher failure loads (IT, 4929 ± 419 N vs. DHS, 3505 ± 453 N; p = 0.036) than the DHS constructs. In comminuted Pauwels type III fractures, the fixation with the IT provided sufficient postoperative mechanical strength, comparable rate of femoral head displacement, and a similar tolerance of physiological loads compared to fractures without comminution. The absence of the posteromedial support in comminuted fractures tended to reduce the failure load regardless of the fixation method.

    Full Text Available Pertrochanteric fractures are common injuries in adults and source of morbidity and mortality among the elderly. Different surgical techniques were recommended for their treatment but undoubtedly they add an additional inflammatory trauma along the fracture itself. Many attempts to quantify the degree of approach-related trauma are carried out through measurements of systemic inflammatory parameters. In this study we prospectively analyzed laboratory data of 20 patients over eighty with pertrochanteric fracture of the femur treated with proximal femoral nail antirotation (PFNA. This is an excellent device for osteosynthesis because it can be easily and quickly inserted by a mini-incision providing stable fixation and early full mobilization. Serum tumor necrosis factor-alpha (TNF-α, interleukin-6 (IL-6, C-reactive protein (CRP, and plasma creatin kinase (CK were evaluated 1 hour preoperatively and 24 hours postoperatively. Our results show that PFNA did not induce significant increments in serum levels of inflammatory cytokines TNF-α and IL-6; CRP was elevated preoperatively in correlation with waiting time for surgery; CRP and CK showed a significant increment in the first postoperatory day; CK increment was correlated with surgical time length. We conclude that, for the markers we analyzed, PFNA shows a low biomechanical-inflammatory profile that represents an advantage over other techniques.

    Full Text Available INTRODUCTION: Sub-trochanteric fractures of the femur remains one of the most challenging fractures faced by orthopaedic surgeons. This study was done to analyse the management and complications of sub-trochanteric fractures using long proximal femoral nail (PFN. MATERIALS AND METHODS: This was a prospective study of 50 patients with sub-trochanteric fractures of femur who were treated with long PFN at a tertiary care center from July 2012 to June 2016. The fractures were classified according to Seinsheimer classification. All patients were assessed functionally by Harris Hip Score. RESULTS: Average duration of union was 17.08 weeks (range 13 to 32 weeks, union was achieved in 92% cases. Closed reduction was achieved in 68% cases and open reduction was required in 32% cases. Various intraoperative complications were seen in 12% and delayed complications in 26% of cases. Good anatomical results were achieved in 86% of cases and 14% were fair. As per Harris Hip score, excellent results were noted in 28% cases, good in 56% cases and fair in 16% cases. CONCLUSION: The long PFN is a reliable implant for sub-trochanteric femur fractures, with high rate of bone union and minimal soft tissue damage. Intramedullary fixation has biological and biomechanical advantages, but the surgery is technically demanding.

    Full Text Available BACKGROUND : Orthopaedic surgeons have long maintained that all children who have sustained a diaphyseal fracture of femur recover with c onservative treatment, given the excellent remodeling ability of immature bone in children. Angulations, shortenings and malrotations are not always corrected by conservative treatment. Of many surgical options, titanium elastic nailing has been the newer implant which is being used regularly. Although good results have been reported with elastic intramedullary nails, plate fixation continues to be a viable alternative in surgical treatment of femoral shaft fractures. However there are not many studies comp aring the efficiency of titanium elastic nailing and plating for femoral diaphyseal fractures in pediatric age group. AIM : The present study aims to compare the surgical management of diaphyseal fractures of femur in children with Dynamic Compression Plati ng versus Titanium Elastic Nailing. DESIGN : This is a prospective study . MATERIALS AND METHODS : This prospective study was conducted in a tertiary hospital. Patients who presented to the out - patient department and casualty of the hospital with femoral diap hyseal fractures during April 2012 to June 2014 were considered for the study. Subjects fulfilling the predetermined inclusion and exclusion criteria were included in the study. STATISTICAL METHODS : Fisher Exact test, Chi - Square Test, Student t test (Two t ailed, independent . RESULTS : Patients in the age group of 6 - 14 years were considered for the study, Patients were divided into two groups and treated with DCP/TENS. The duration of surgery, hospital stay, and, amount of blood loss was minimal in TENS grou p. Callus was seen early in TENS group. Radiological union was early in TENS group by 2 - 3 weeks. Outcome was better in patients treated with TENS (Excellent - 70%; Satisfactory – 30%; Poor - 0% in comparison to DCP (Excellent - 70%; Satisfactory - 25%; Poor - 5%. CO NCLUSION : TENS

    Full Text Available The purpose - to study structural changes in knee articular cartilage and synovial membrane during locking intramedullary osteosynthesis of femoral fractures. Material and methods. The study tested structural changes in the articular cartilage of the femoral condyles and synovium during femoral fracture repair under the conditions of intramedullary locked nailing. Transverse diaphyseal femoral fractures were modeled in 12 adult mongrel dogs. Synovitis severity was assessed with a V. Krenn scale. Wilcoxon Test was used for testing hypothesis. Results. In the first group (n = 6 fractures were fixed with locked intramedullary nails ILoc (Biomedtrix, USA, while the same type of fixation in group 2 (n = 6 was performed on 4th day postoperatively after reduction by skeletal traction. It was revealed that in the first group a unified medullary cavity was seen by day 70 and the cortical layer at the fracture site approximated to the condition of the uninjured bone in intensity of bone formation and thickness. These featured were observed in the second group only by day 100. The histological study showed that the structure of the femoral condyle articular cartilage was regular in the first group but its changes were reduced thickness and reduced volumetric density of chondrocytes that might result due to disturbed trophical condition. In the second group the articular cartilage fibres tended to disintegrate on the surface that was accompanied by disturbed integrity of the basophil line and penetration of the vessels into the cartilage. Moreover, the cartilage destruction progressed as the experiment continued and chondrocyte proliferation sharply decreased. Synovitis was considerably expressed. The data obtained in the second group proved high risk of developing osteoarthrosis.

    Full Text Available AIMS AND OBJECTIVES : To determine the rate of union, complications, operative risks and functional outcomes in intertrochanteric fractures treated with DHS and PFN , To compare the results obtained and To compare the effectiveness of DHS and PFN in treatment of intertrochanteric fractures. RESULTS : In the present series of 24 cases of Intertrochanteric fractures were treated by proximal femoral nailing and dynamic hip screw, 12 cases in each. Out of 24 there were 13 male and 11 female. Minimum age was 36 years, maximum age 76 years with mean age of 59.25 years. Slip and fall accounted for 75% of cases. BOYD and GRIFFIN type II fracture accounted for 58.3% of cases. Mean duration of hospital stay was 26 days in both PFN and DHS groups. Length of incision was small 5 - 6cm in PFN group compared to 10 - 12cm in DHS group. Mean external blood loss 150ml in PFN group and 315 ml in DHS group. Mean time for full weight bearing was 11.5 weeks for PFN group and 14.3 weeks for DHS group. Radiological union was 12.3 weeks in PFN group and 15.5 weeks in DHS group. Good to excellent results were seen in 91.7% of cases in PFN group and 75% in DHS group. CONCLUSION : From the study, we consider PFN as better alternative to DHS in the treatment of intertrochanteric fractures but is technically difficult procedure and requires more expertise compared to DHS.As learning curve of PFN procedure is steep, with experience gained from each case operative time, radiation exposure and intraoperative complications can be reduced in each case of PFN

    Intramedullary nails are the primary choice for treating long bone fractures. However, complications following nail surgery including non-union, delayed union, and fracture of the bone or the implant still exist. Reducing nail stiffness while still maintaining sufficient stability seems to be the ideal solution to overcome the abovementioned complications. In this study, a new hybrid concept for nails made of carbon fibers/flax/epoxy was developed in order to reduce stress shielding. The mechanical performance of this new implant in terms of fracture stability and load sharing was assessed using a comprehensive non-linear FE model. This model considers several mechanical factors in nine fracture configurations at immediately post-operative, and in the healed bone stages. Post-operative results showed that the hybrid composite nail increases the average normal force at the fracture site by 319.23N (P<0.05), and the mean stress in the vicinity of fracture by 2.11MPa (P<0.05) at 45% gait cycle, while only 0.33mm and 0.39mm (P<0.05) increases in the fracture opening and the fragments' shear movement were observed. The healed bone results revealed that implantation of the titanium nail caused 20.2% reduction in bone stiffness, while the composite nail lowered the stiffness by 11.8% as compared to an intact femur. Our results suggest that the composite nail can provide a preferred mechanical environment for healing, particularly in transverse shaft fractures. This may help bioengineers better understand the biomechanics of fracture healing, and aid in the design of effective implants. Copyright © 2014. Published by Elsevier Ltd.

    Treatment for bone defect remains a challenge for orthopedists. Bone transport gives an effective alternative, which can be performed with an external fixator alone or combined with an intramedullary nail. Each has its advantages and disadvantages. We present a retrospective study to find out the optimal choice by evaluating the outcomes of treatment for femoral bone defect with two methods. Two groups of patients, the monolateral external fixator alone (group A, n = 13) and the monolateral external fixator combined with intramedullary nail (group B, n = 15), were compared. Duration of the external fixator, external fixator index, radiographic consolidation index, complication, and total cost for treatment was also recorded. A modified classification of the Association for the Study and Application of the Method of Ilizarov (ASAMI) was used to assess results in two groups of patients; another SF-36 health survey questionnaire was used to assess the life qualities patients of two groups. Healing was achieved in 13/13 and 13/15 of the two groups, respectively. The rates of complications were significantly higher in the group A. Two patients performed amputations because of persistent deep infections in group B. Statistically significant difference was found when comparing ASAMI scores and categories of the SF-36 health survey. Bone transport by monolateral external fixator with the use of intramedullary nail reduces the incidence of complication and the duration of external fixator time that give patients a better life quality in both physical and emotional. However, if chronic osteitis exists, bone transport should be treated with monolateral external fixator alone due to a lower rate of amputations.

    Proximal Femoral Nailing (PFN) in Intertrochanteric Fractures (IF) is becoming the choice of implant due to better biomechanics and prevention of varus collapse associated with Dynamic Hip Screw (DHS). Technical difficulties and implant related complications are yet to be addressed. To understand the technical difficulties involved in PFN and role of provisional fixation of fracture by Steinmann-pin. In this study, 55 patients presented to a tertiary trauma center in India with trochanteric fractures from April 2010 to March 2012 were included and treated with PFN. All patients were followed-up for two years and final outcome assessment included shortening, neck shaft angle and Harris Hip Score was done. In all except one, neck shaft angle greater than 130° was achieved and also maintained in the final follow up (Mean 131.1°). All fractures were united with mean shortening of 3.6 mm and average Harris Hip Score of 91 after two years. There were five complications which included one shortening, two varus collapses, one backed out screws and one reverse Z effect. Though PFN is technically challenging, with proper technique, gives excellent results with negligible varus collapse even in unstable fractures. Three most important technical aspects are achieving good non-varus reduction, inserting nail correctly and accurate placement of lag screws. The technique of provisional fixation of fracture fragments by Steinmann-pin significantly helps in achieving these and reduces the risk of implant failure.

    Full Text Available Abstract Background Early intramedullary nailing (IMN of long bone fractures in severely injured patients has been evaluated as beneficial, but has also been associated with increased inflammation, multi organ failure (MOF and morbidity. This study was initiated to evaluate the impact of primary femoral IMN on coagulation-, fibrinolysis-, inflammatory- and cardiopulmonary responses in polytraumatized patients. Methods Twelve adult polytraumatized patients with femoral shaft fractures were included. Serial blood samples were collected to evaluate coagulation-, fibrinolytic-, and cytokine activation in arterial blood. A flow-directed pulmonary artery (PA catheter was inserted prior to IMN. Cardiopulmonary function parameters were recorded peri- and postoperatively. The clinical course of the patients and complications were monitored and recorded daily. Results Mean Injury Severity Score (ISS was 31 ± 2.6. No procedure-related effect of the primary IMN on coagulation- and fibrinolysis activation was evident. Tumor necrosis factor alpha (TNF-α increased significantly from 6 hours post procedure to peak levels on the third postoperative day. Interleukin-6 (IL-6 increased from the first to the third postoperative day. Interleukin-10 (IL-10 peaked on the first postoperative day. A procedure-related transient hemodynamic response was observed on indexed pulmonary vascular resistance (PVRI two hours post procedure. 11/12 patients developed systemic inflammatory response syndrome (SIRS, 7/12 pneumonia, 3/12 acute lung injury (ALI, 3/12 adult respiratory distress syndrome (ARDS, 3/12 sepsis, 0/12 wound infection. Conclusion In the polytraumatized patients with femoral shaft fractures operated with primary IMN we observed a substantial response related to the initial trauma. We could not demonstrate any major additional IMN-related impact on the inflammatory responses or on the cardiopulmonary function parameters. These results have to be interpreted

    Full Text Available BACKGROUND Intertrochanteric fractures are one the common fractures encountered in today’s orthopaedic practice. Intertrochanteric fractures are devastating injuries that most commonly affect the elderly population, but not increased in the younger population. In young and healthy individuals, the injury results from high energy trauma, whereas in the elder age group, most of the fractures are osteoporotic resulting from a trivial fall. MATERIALS AND METHODS This study was conducted in Konaseema Institute of Medical Sciences, Amalapuram, from July 2013 to September 2016. During this period, adult patients with pertrochanteric fractures of femur were classified according to Boyd and Griffin classification and 40 patients were selected according to inclusion criteria. This study was conducted with due emphasis for clinical observation and analysis of results after surgical management of these fractures of femur with dynamic hip screw or proximal femoral nailing. RESULTS Anatomical results were assessed by presence or absence of shortening, range of movements and deformities. 70% of the cases had good results in PFN series as compared to 65% in DHS series. Functional results were assessed in the 40 cases. These constituted of 20 cases in PFN series and 20 cases in DHS series. In PFN series, results were excellent results in 7 cases, good in 6 cases, fair in 2 cases and poor in 5 cases. In DHS series, results were excellent in 5 cases, good in 9 cases, fair in 2 cases and poor in 4 cases. CONCLUSION An intertrochanteric fracture of the femur is common in the elderly due to osteoporosis and in young due to high velocity trauma. As the fracture is more common in the elderly, early reduction and internal fixation increases patient comfort, facilitates nursing care, helps in early mobilisation of the patient and decreases the duration of hospitalisation. Anatomical reduction can be achieved by closed manipulation or open methods. As the incidence of

    , devido a uma redução inadequada em varo, ocorreu um cutout que necessitou de revisão cirúrgica. Outro caso de fratura do tipo 31A2, evoluiu para necrose avascular da cabeça femoral, após consolidação da fratura. Por fim, um caso de fratura do tipo 31A3, devido a redução inadequada no plano sagital, evoluiu para retarde de consolidação, com quebra da haste após 13 meses da cirurgia. CONCLUSÃO: A osteossíntese com haste proximal, como tratamento da fratura trocantérica instável do fêmur realizada em pacientes com idade superior a 60 anos, resultou na consolidação da maioria dos casos. As complicações foram distintas nos dois subgrupos estudados. A redução adequada da fratura antes da introdução da haste intramedular é fundamental para o sucesso do procedimento.OBJECTIVE: Identifying the rate of healing of unstable trochanteric fractures submitted to osteosynthesis with a proximal femoral nail (PFN® - AO/ASIF, in patients operated on between November 1999 and March 2004. METHODS: 45 patients were analyzed, ages ranging from 60 to 93, with unstable trochanteric fractures of the femur submitted to osteosynthesis with short PFN®, with indirect reduction in a traction device guided by radioscopy. The fractures were classified according to the AO/OTA classification. Bone quality was evaluated by the Singh index in the post-operative radiographic routine. The quality of the reduction achieved and the positioning of the implant were evaluated by post-operative anteroposterior and profile X-ray of the proximal femur, with analysis of the cervicodiaphyseal angle and the distance between the tip of the sliding nail and the center of the femoral head, the so-called "tip apex distance" (TAD. RESULTS: The mean age of patients studied was 80.8 years (60-93. Females prevailed, with 37 cases (82.2%. The right side was involved in 22 cases (48.89% and the left side, in 23 (51.1%.

    Full Text Available Nail dyschromias have a wide variety of presentation. There are numerous causes of discoloration of the nail affecting the nail plate, nail attachments, or the substance of the nail. The chromonychia may also be caused due to the exogenous deposition of pigments over the nail plate. Careful examination of the nail and few bed side tests may help in identifying the root cause of the nail dyschromia and many a times unravels some underlying systemic disorder too.

    Full Text Available Introduction: The elastic stable intramedullary nailing (ESIN presently seems the best technique in the surgical treatment of femoral shaft fractures (FSF in >6-year-old children. We hereby report technical difficulties and therapeutic results after our first 8 years of experience. Patients and Methods: It′s a retrospective study over a period of 8 years from January 2005 to December 2012 in the Paediatric Surgery Department of Sylvanus Olympio Teaching Hospital of Lomé. Indications, technical particularities and results were studied. Results: There were 32 patients, 17 were boys and 15 were girls, with a mean age of 11 years old. The mean time to surgery was 21 days (range: 14 and 51 days. A callus was always removed before reduction. The osteosynthesis was stable in 22 cases, but in 10 others, it had been completed with a cast immobilisation. The operation needed a blood transfusion in 18 cases. With a mean follow-up of 3.5 years, the results were excellent in 29 patients (90.63% and good in 3 patients (9.37%. Conclusion: Although undertaking an ESIN can be difficult, due to the lack of adequate equipment the procedure produces satisfactory outcome.

    The nail unit comprises the nail plate, the surrounding soft tissues, and their vasculature and innervation based upon the distal phalanx. The nail plate is a laminated keratinized structure lying on the nail matrix (15-25%), the nail bed with its distal onychodermal band (75-85%), and the hyponychium at its free edge. The distal part of the matrix, the lunula characterized by its half-moon shape, can be observed in some digits. The nail plate is embedded by the proximal and lateral folds. From the proximal nail fold, the cuticle (also known as the eponychium), adheres to the superficial surface of the proximal nail plate. The nail unit possesses a complex and abundant vascular network to ensure adequate blood supply. Finally, both the periungual soft tissues and the nail folds are innervated. The shapes, structure, and inter-relationships of these tissues are factors in the way nails present with disease and how we understand and manage those diseases. In particular, an understanding of the surgical anatomy is important for those undertaking diagnostic or curative operations on the nail. With this knowledge, the most appropriate surgery can be planned and the patient can be provided with accurate and clear guidance to enable informed consent. © 2013.

  16. Staged protocol for the treatment of chronic femoral shaft osteomyelitis with Ilizarov's technique followed by the use of intramedullary locked nail

    2017-06-01

    Conclusion: In the treatment of chronic femur osteomyelitis, the staged protocol of Ilizarov distraction osteogenesis followed by intramedullary nailing was safe and successful, and allowed for union, realignment, reorientation, and leg-length restoration. With regard to the soft tissue, this technique provides a unique type of reconstructive closure for infected wounds. It is suggested that the staged protocol is reliable in providing successful simultaneous reconstruction for bone and soft tissue defects without flap coverage.

  17. Nail infections.

    1989-04-01

    Nail infections are and will continue to be a diagnostic and therapeutic challenge to all foot physicians. Attention to basic concepts of accurate detailed history and physical examination will aid in the determination of the etiology of these infections. Following basic guidelines of incision and drainage, gram stain, soaks, and antibiotics will be the cornerstone of initial treatment of pyogenic infections. Upon resolution of the acute infection a permanent treatment plan can be constituted based on the etiology. Nail infections of mycotic nature require an understanding by both patient and doctor as to the difficulty and resistance to treatment of this problem. It is the authors' opinion that aggressive persistent treatment will provide the best long-term result when dealing with mycotic infections. This may require nail removal, local and systemic treatment as well as change in shoe environment. As we have seen and is stated throughout this text, the nail and its pathologic processes can be a mirror of systemic disease. Many times a dystrophic infected nail may be the initial clinical presentation of a much more involved disease process. It is the responsibility and duty of all foot physicians to have a total understanding of knowledge of normal and pathologic process that affect the nail plates, nail bed, and surrounding nail proper. I hope this article will stimulate the foot physician to approach the disease of the nail with a high index of suspicion and respect.

    The structure of the nail unit is complex and many dermatologists and dermatopathologists have an incomplete understanding of it. Familiarity with the anatomy and histology of this unit, however, is a key factor in improving the diagnostic yield of nail biopsy. Inflammatory or infectious conditions that affect the nail can have a marked impact on a patient's quality of life. A wide-ranging variety of tumors can also develop in this region and they may be life-threatening or require surgery that will result in functional defects. The author reviews the anatomy and histology of the nail unit as well as the basic histopathologic findings in the most common conditions affecting the nails.

    Full Text Available While operating on the hip joint, breaking of guide wire became a challenge for treating orthopedic surgeon. Here we report a simple method of removal, which requires limited resources and does not need sophisticated instrumentation. By using this method, we remove broken guide wire in a patient of sub-trochantric fracture of femur managed by close reduction and internal fixation by proximal femoral nail. During the removal of the guide wire, after placing distal screw in the neck the guide wire comes out with some difficulty in the final view on image intensifier - the guide wire broken and transfixes the hip joint but does not enter the pelvis. After removal of the distal screw, its cannulated drill bit was connected to a T-handle and introduced into the track of distal screw up to the broken distal end of guide wire and slow manual reaming done under C-arm image intensifier to prevent damage to the articular cartilage. This process was repeated three times after cleaning drill bit each time to clear the base of guide wire for grasping its distal end. With the help of Kerryson rounger/grasper, the distal end of the guide wire was grasped and easily removed. The distal screw was placed in its original track and the procedure was completed.

  11. Dynamic compression nail: A preliminary report

    Directory of Open Access Journals (Sweden)

    Gupta Ajay

    2001-10-01

    Full Text Available Abstract Background Interlocking nailing, which has become the method of choice for treating fractures of the femoral and tibial shafts, still lacks ability to provide the important contact-compression at the fracture. An intramedullary compression nail is described, which provides axial compression at the fracture site with tightening of the specially designed distal interlocking screw. This uses the same principle as dynamic compression plating. Methods The study included 11 femoral and tibial nailings performed for various clinical applications such as acute fractures, non-unions and malunions. Results All the fractures attained radiological union, with good skeletal continuity across the fracture, within an average time of 13 weeks in fresh fractures and 18 weeks in non-unions. Conclusions Active compression through intramedullary compression nailing has great utility for treating non-unions where it provides greater degree of impaction of its irregular ends. This may prove greatly advantageous to the fracture union through increased stability and the osteogenic potential, particularly when utilized in combination with the small diameter unreamed nails.

    Clinical symptoms attributed to the nail apparatus and observed in cosmetology include atrophic or hypertrophic lesions, pathologic nail coloration, abnormalities of the nail surface, and disorders of the nail plate and bed junction. These symptoms may reflect pathologic processes limited to the nail apparatus or may be the consequence of a dermal or systemic disease. Even though the etiology of nail lesions is variegated, diseases of the nails are simply classified as infectious or non-infectious. The aim of this work was to present the most common diseases of the nail apparatus encountered in cosmetology. Often, nail diseases worsen the quality of life of the patient. In addition, the variegated symptomatology demonstrates that nail lesions should be viewed in a wider perspective because they often are important signs of pathologic processes taking place in the organism of the patient.

    The nail is a specialized keratinous skin appendage that grows approximately 2 to 3 mm per month, with complete replacement achieved in 6 to 9 months. Although this structure can be easily overlooked, nail disorders comprise approximately 10% of all dermatologic conditions. This contribution first provides an overview on the basic anatomy of the nail that will delineate between the nail unit (eg, hyponychium, nail bed, proximal nail fold, and matrix) and anatomic components not part of the nail unit (eg, lateral nail folds, nail plate, and eponychium). The function of each nail structure will also be presented. The chemical profile of the normal nail plate is reviewed with a discussion of its keratin content (hair type keratin vs epithelial type keratin), sulfur content, and mineral composition, including magnesium, calcium, iron, zinc, sodium, and copper. The remainder will focus on nail manifestations seen in states of malnutrition. Virtually every nutritional deficiency can affect the growth of the nail in some manner. Finally, the discussion will include anecdotal use of nutritional and dietary supplements in the setting of brittle nail syndrome as well as a brief overview of biotin and its promising utility in the treatment of nail disorders.

  18. Expanding nail or expanding femur? An adverse event with the expandable intramedullary nail.

    Science.gov (United States)

    Gangopadhyay, Soham; Riley, Nicholas D; Sivaji, Chellappan K

    2010-01-01

    The expandable intramedullary nail is self-locking and has the advantage of reducing operating time and exposure to ionizing radiation. The nail is recommended for simple diaphyseal fractures involving the middle third of long bones, where the nail can bypass the fracture site by at least 5 cm. We encountered a unique complication with the expandable nail in a simple transverse shaft fracture at the junction of the middle and distal third of the left femur in an otherwise healthy 57-year-old man. The fracture was reduced and a 12-mm expandable nail was inserted. Following full expansion, intraoperative radiographs were obtained prior to closure. After six postoperative weeks, it was noted that the nail expanded the femoral canal, converting a simple fracture to a distally progressing comminuted fracture with a butterfly fragment. A review of the intraoperative radiographs showed slight widening of the medullary canal at the level of the fracture. As the alignment was satisfactory and callus was present, no further surgical intervention was considered. The patient was advised not to bear weight and was provided with a locked knee brace in extension to wear for six weeks. Radiographs at 12 weeks demonstrated good progress of healing with adequate callus and the patient was permitted to bear weight as tolerated and commence knee flexion. The fracture united satisfactorily at four months. This adverse experience emphasizes that caution should be exercised when expanding the nail, with close observation of the medullary canal diameter during the later stages of expansion.

    Roman hihstorian Pliny the Younger noted that Mount Vesuvius blew its top and destroyed Pompeii in the early afternoon of August 24, 1,918 years ago. Now, a team of scientists, tempted by the certainty of that record, has confirmed the eruption to within 7 years. The team developed and used an improved radioactive argon-argon dating technique, which they say can reliably establish the age of rocks as old as the solar system or as recent as 1,000 years old.“We nailed the date to 5% on our first attempt, so we could probably get the error down to 1% or less,” says Paul Renne, adjunct associate professor of geology and geophysics at the University of California at Berkeley and director of the private Berkeley Geochronology Center. “Dating things that are really young has always been the Holy Grail of potassium-argon [an earlier method] and argonargon dating.”

    Diagnosing nail matrix diseases requires knowledge of the nail matrix function and anatomy. This allows recognition of the clinical manifestations and assessment of potential surgical risk. Nail signs depend on the location within the matrix (proximal or distal) and the intensity, duration, and extent of the insult. Proximal matrix involvement includes nail surface irregularities (longitudinal lines, transverse lines, roughness of the nail surface, pitting, and superficial brittleness), whereas distal matrix insult induces longitudinal or transverse chromonychia. Clinical signs are described and their main causes are listed to enable readers to diagnose matrix disease from the nail's clinical features. Copyright © 2015 Elsevier Inc. All rights reserved.

    While intramedullary nailing has been established as the treatment of choice for diaphyseal fractures of the femur and tibia, its role in the management of diaphyseal humeral fractures remains controversial. The reasons include not only the complicated anatomy and unique biomechanical characteristics of the arm but also the fact that surgical technique and nail designs devised for the treatment of femoral and tibial fractures are being transposed to the humerus. As a result there is no consensus on many aspects of the humeral nailing procedure, e.g., the basic nail design, nail selection criteria, timing of the procedure, and the fundamental principles of the surgical technique (e.g., antegrade/retrograde, reamed/unreamed, and static/dynamic). These issues will be analyzed and discussed in the present article. Proposals aiming to improve outcomes include the categorization of humeral nails in two distinct groups: “fixed” and “bio”, avoidance of reaming for the antegrade technique and utilization of “semi-reaming” for the retrograde technique, guidelines for reducing complications, setting the best “timing” for nailing and criteria for selecting the most appropriate surgical technique (antegrade or retrograde). Finally, suggestions are made on proper planning and conducting clinical and biomechanical studies regarding the use of intramedullary nailing in the management of humeral shaft fractures.

    Knowledge of the anatomy and function of the nail apparatus is essential when performing the physical examination. Inspection may reveal localized nail abnormalities that should be treated, or may provide clues to an underlying systemic disease that requires further workup. Excessive keratinaceous material under the nail bed in a distal and lateral distribution should prompt an evaluation for onychomycosis. Onychomycosis may be diagnosed through potassium hydroxide examination of scrapings. If potassium hydroxide testing is negative for the condition, a nail culture or nail plate biopsy should be performed. A proliferating, erythematous, disruptive mass in the nail bed should be carefully evaluated for underlying squamous cell carcinoma. Longitudinal melanonychia (vertical nail bands) must be differentiated from subungual melanomas, which account for 50 percent of melanomas in persons with dark skin. Dystrophic longitudinal ridges and subungual hematomas are local conditions caused by trauma. Edema and erythema of the proximal and lateral nail folds are hallmark features of acute and chronic paronychia. Clubbing may suggest an underlying disease such as cirrhosis, chronic obstructive pulmonary disease, or celiac sprue. Koilonychia (spoon nail) is commonly associated with iron deficiency anemia. Splinter hemorrhages may herald endocarditis, although other causes should be considered. Beau lines can mark the onset of a severe underlying illness, whereas Muehrcke lines are associated with hypoalbuminemia. A pincer nail deformity is inherited or acquired and can be associated with beta-blocker use, psoriasis, onychomycosis, tumors of the nail apparatus, systemic lupus erythematosus, Kawasaki disease, and malignancy.

    The colour of a nail polish varies according to the nail on which it is applied. The objective of this study was to predict the colour of the nail polish on a given nail and to study how the colour varies depending on the nail polish thickness. Six nail polishes were applied in one, two and three layers on the nails of one subject, thus forming eighteen samples. The spectral reflectances of the eighteen nail polishes applied on the nails with different thicknesses were obtained by spectrophotometry. The spectral reflectances of the nails without polish were also measured using the same technique. The thicknesses of nail polishes were measured by high-definition optical coherence tomography (HD-OCT). Then, to determine the physical parameters of the nail polish itself, we applied the six nail polishes on an opacity drawdown chart and we measured the spectral reflectance and the thickness of each patch using spectrophotometry and HD-OCT, respectively. The Kubelka-Munk theory was used to get the predicted spectral reflectance of the nail polish applied on the nail according to the polish thickness by knowing the parameter of the polish itself and the spectral reflectance of the nail. The predicted spectral reflectances were finally compared with those measured directly on the nails. The predicted spectral reflectances were rather close to measured ones. Consequently, knowing the colour of the nail without polish and the optical parameters of the nail polish itself, we can estimate the colour of the nail polish applied on the nail depending on its thickness. Our study showed that the Kubelka-Munk theory can be used to predict the nail polish colour. The ability to predict the real colour of a nail polish applied on a nail could help a nail polish manufacturer to improve his polish formulae in order to obtain a precise colour. © 2017 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    A variety of nail deformities commonly presents in the primary care office. An understanding of nail anatomy coupled with inspection of the nails at routine office visits can reveal undetected disorders. Some problems are benign, and treatment should be attempted by the primary care provider, such as onychomycosis, paronychia, or ingrown toenails. For conditions such as benign melanonychia, longitudinal ridges, isolated Beau lines, and onycholysis, clinicians may offer reassurance to patients who are concerned about the change in their nails. For deformities such as early pterygium or clubbing, a thorough evaluation and referral to an appropriate specialist may be warranted. Copyright © 2015 Elsevier Inc. All rights reserved.

    Femoral shaft fracture is one of the common fractures seen in accident and emergency department of our hospital. Violent forces are required to break this and strongest of human bones. There are various treatment modalities for femoral shaft fractures in adults like traction, brace, platting, intramedullary nail (IMN), external fixators and inter locking nails. The study was done with an objective to evaluate the results of closed reamed interlocking nail in fractures of shaft of femur. A prospective study of 114 cases of femoral shaft fractures was carried out at orthopaedic unit of Ayub Teaching Hospital Abbottabad during 1 year. All these cases were treated with statically locked nails under spinal or general anaesthesia. These cases were followed up for up to one year and Results of the interlocking nail were observed in terms of union and complications. Out of 114 patients, 95 underwent union in 90-150 days with a mean of 110.68 days. Ten patients had dynamization within six weeks because of obvious fracture gap in radiograph. There were 3 patients who had non-union, and 6 patients had delayed union which was treated with dynamization. Close reamed interlocking intramedullary nail in femoral shaft fractures is the treatment of choice. Patient rehabilitation is early, hospitalization is short, and fracture healing response is good.

  4. Drug-induced nail disorders.

    Science.gov (United States)

    2014-07-01

    Nail disorders are defined according to their appearance and the part of the nail affected: the nail plate, the tissues that support or hold the nail plate in place, or the lunula. The consequences of most nail disorders are purely cosmetic. Other disorders, such as ingrown nails, inflammation, erythema, abscesses or tumours, cause functional impairment or pain. The appearance of the lesions is rarely indicative of their cause. Possible causes include physiological changes, local disorders or trauma, systemic conditions, toxic substances and drugs. Most drug-induced nail disorders resolve after discontinuation of the drug, although complete resolution sometimes takes several years. Drugs appear to induce nail disorders through a variety of mechanisms. Some drugs affect the nail matrix epithelium, the nail bed or the nail folds. Some alter nail colour. Other drugs induce photosensitivity. Yet others affect the blood supply to the nail unit. Nail abnormalities are common during treatment with certain cytotoxic drugs: taxanes, anthracyclines, fluorouracil, EGFR, tyrosine kinase inhibitors, etc. Some drugs are associated with a risk of serious and painful lesions, such as abscesses. When these disorders affect quality of life, the benefits of withdrawing the drug must be weighed against the severity of the condition being treated and the drug's efficacy, taking into account the harm-benefit balance of other options. Various anti-infective drugs, including tetracyclines, quinolones, clofazimine and zidovudine, cause the nail plate to detach from the nail bed after exposure to light, or cause nail discoloration. Psoralens and retinoids can also have the same effects.

    Full Text Available Six techniques not yet widely known or used in the dermatologic surgery of the nails are briefly described. Small-to-medium-sized tumours of the proximal nail fold (PNF can be excised and the defect repaired with advancement or rotation flaps. A superficial biopsy technique of the matrix for the diagnosis of longitudinal brown streaks in the nail, which allows rapid histological diagnosis of the melanocyte focus to be performed, is described here. Because the excision is very shallow and leaves the morphogenetic connective tissue of the matrix intact, the defect heals without scarring. Laterally positioned nail tumours can be excised in the manner of a wide lateral longitudinal nail biopsy. The defect repair is performed with a bipedicled flap from the lateral aspect of the distal phalanx. Malignant tumours of the nail organ often require its complete ablation. These defects can be covered by a full-thickness skin graft, reversed dermal graft, or cross-finger flap. The surgical correction of a split nail is often difficult. The cicatricial tissue of the matrix and PNF have to be excised and the re-attachment of these wounds prevented. The matrix defect has to be excised and sutured or covered with a free matrix graft taken either from the neighbouring area or from the big toe nail.

    This study assessed whether radiolucent carbon fiber reinforced-polyetheretherketone (CFR-PEEK) intramedullary nails decreased hardware artifact on magnetic resonance imaging (MRI) and computed tomography (CT) in vitro and in an oncologic patient population. In vitro and clinical evaluations were done. A qualitative assessment of metal artifact was performed using CFR-PEEK and titanium nail MRI phantoms. Eight patients with a femoral or tibial prophylactic CFR-PEEK nail were retrospectively identified. All patients had postoperative surveillance imaging by MRI, CT, and were followed for a median 20 months (range, 12-28 months). CFR-PEEK images were compared to images from a comparative group of patients with titanium femoral intramedullary nails who had a postoperative MRI or CT. A musculoskeletal-trained radiologist graded visualization of the cortex, corticomedullary junction, and bone-muscle interface, on T1-weighted (T1W), STIR, and contrast-enhanced T1-weighted fat-saturated (T1W FS) sequences of both groups with a five-point scale, performing independent reviews 4 months apart. Statistical analysis used the Wilcoxon rank-sum test and a weighted kappa. Substantially less MRI signal loss occurred in the CFR-PEEK phantom than in the titanium phantom simulation, particularly as the angle increased with respect to direction of the static magnetic field. CFR-PEEK nails had less MRI artifact than titanium nails on scored T1W, STIR, and contrast-enhanced T1W FS MRI sequences (p ≤ 0.03). The mean weighted kappa was 0.64, showing excellent intraobserver reliability between readings. CFR-PEEK intramedullary nail fixation is a superior alternative to minimize implant artifact on MRI or CT imaging for patients requiring long bone fixation. (orig.)

    This article provides an updated review on diagnosis and treatment of inflammatory nail disorders including psoriasis, lichen planus, trachyonychia, and autoimmune bullous disorders. Despite the significant negative repercussion of the nail psoriasis in the quality of life of patients, treatment is often not sufficiently effective. The efficacy of topical therapies is limited to nail bed psoriasis. Intralesional corticosteroid injections are extensively utilized in nail matrix psoriasis. Systemic immunosuppressant drugs such as methotrexate and cyclosporine have shown efficacy. Biologics, particularly infliximab and etanercept, have also demonstrated high efficacy in the treatment of severe nail disease. Nail matrix lichen planus can cause nail atrophy and irreversible nail scarring and requires prompt treatment with systemic steroids. There is not gold standard therapy for trachyonychia, but in most cases the nail signs improve spontaneously and treatment is not necessary. Nail changes in pemphigus and other autoimmune disorders respond promptly to systemic therapy with steroids and immunosuppressants. © 2012 Wiley Periodicals, Inc.

  14. Nail cosmetics: allergies and irritations.

    Science.gov (United States)

    Baran, Robert

    2002-01-01

    Recent precise figures are not available for the number of adverse reactions related to the use of nail care products. Reactions to nail cosmetic procedures may be divided into reactions at the site of application to the nail itself and ectopic reactions, when the hand transfers a small amount of nail cosmetic to other areas of the skin. Fingernail coatings encompass two types: coatings that harden upon evaporation (nail enamel, base coat, top coat); and coatings that polymerize (sculptured nails, light-curing gels, preformed artificial nails, nail mending and nail wrapping). The test battery enables us to distinguish allergic reactions from irritant reactions. Interestingly, some reactions, such as distant allergic contact dermatitis, are more frequent with nail enamel than with coatings that polymerize. On the other hand, the latter are greater offenders in the nail area. Nail hardeners may just be modified nail enamels containing nylon fibers, acrylate resin and hydrolyzed proteins. Others may contain up to 5% formaldehyde tissue fixative (which can have adverse effects on the nail), but are designed in the US to be applied only to the free edge of the nail while the skin is shielded. Caution is necessary in interpreting formaldehyde patch testing reactions.

    Atypical femoral fractures can be subsequent to a long-term biphosphonates treatment; they have a high frequency of delayed healing. The authors describe a femoral pseudoarthrosis of an atypical fracture treated with intramedullary nailing in a female after prolonged alendronate therapy. Atypical femoral fractures can be subsequent to a long-term biphosphonates treatment even if, in the literature, there is no clarity on the exact pathogenetic mechanism. The Task Force of the American Society for Bone and Mineral Research described the major and minor features to define atypical fractures and recommends that all the five major features must be present while minor features are not necessary. Another controversial aspect regarding the atypical femoral fractures is the higher frequency of the delayed healing that can be probably related to a suppressed bone turnover caused by a prolonged period of bisphosphonates treatment. This concept could be corroborated by the Spet Tc exam. In the case of a pseudoarthrosis, there is not a standardization of the treatment. In this report, the authors describe a femoral pseudoarthrosis of an atypical fracture treated with intramedullary nailing in a female after prolonged alendronate therapy; the patient was studied with clinical, bioumoral end SPECT-Tc exam of both femurs. Many studies show the relationship between bisphosphonates and the presence of atypical fractures. These fractures should be monitored more closely due to the risk of nonunion and they require considering an initial treatment with pharmacological augmentation to reduce the complications for the patient and the health care costs.

    Nail clipping specimens are commonly submitted for the microscopic evaluation of nail disease; however, there may be missing clinical history regarding nail polish or other adornments present on the nail at the time of specimen retrieval. For this study, 6 types of nail cosmetics were chosen and applied to the nail plate of a volunteer. After a period of at least 24 hours, the nail plates with adornments and a control nail plate were clipped and placed in formalin. Specimens were processed using a standard nail protocol. All of the specimens, except the sticker appliqué, survived the fixation process. The glitter nail polish was the only specimen found to be polarizable. None of the specimens that survived fixation were found to be PAS-positive. Cosmetic nail enhancements are easily differentiated from the nail plate microscopically; nail cosmetics appear as a distinct layer of inorganic material lying atop the nail plate. There were 2 main microscopic patterns noted on the specimens: those with 2 layers and those with 3 layers.

    Cosmetic embellishment of fingernails involves the use of substance that harden either after the evaporation of solvents (varnishes) or after polymerisation (artificial acrylic nails, gel tips, glue-on artificial nails). Pathological reactions to cosmetics usually occur at a remote site for varnishes, and, most commonly, in situ with polymerising substances. Unvarnished artificial nails do not affect pulse oximetry readings, and in theory, patients are not required to remove them. However, a real problem of contamination via artificial nails exists. Increased carriage of pathological Gram-negative organisms and of Staphylococcus aureus and yeasts has been noted among nursing staff wearing artificial nails, both before and after fingernail cleaning. Fingernail fragility manifests itself through a number of different physical signs such as soft, breaking nails, with longitudinal or transverse fissures, showing distal doubling or friability. In some subjects, excessive manicuring with metal instruments or manicure sticks results in rolled onycholysis, of evocative appearance, or transverse onycholysis. Copyright © 2016.

    Two types of implants used for the surgical fixation of extracapsular hip fractures are cephalocondylic intramedullary nails, which are inserted into the femoral canal proximally to distally across the fracture, and extramedullary implants (e.g. the sliding hip screw). To compare cephalocondylic intramedullary nails with extramedullary implants for extracapsular hip fractures in adults. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (June 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 2), MEDLINE (1966 to June week 3 2007), EMBASE (1988 to 2007 Week 27), the UK National Research Register, orthopaedic journals, conference proceedings and reference lists of articles. All randomised and quasi-randomised controlled trials comparing cephalocondylic nails with extramedullary implants for extracapsular hip fractures. Both authors independently assessed trial quality and extracted data. Wherever appropriate, results were pooled. Predominantly older people with mainly trochanteric fractures were treated in the 36 included trials.Twenty-two trials (3871 participants) compared the Gamma nail with the sliding hip screw (SHS). The Gamma nail was associated with an increased risk of operative and later fracture of the femur and an increased reoperation rate. There were no major differences between implants in the wound infection, mortality or medical complications.Five trials (623 participants) compared the intramedullary hip screw (IMHS) with the SHS. Fracture fixation complications were more common in the IMHS group; all cases of operative and later fracture of the femur occurred in this group.

    2012-02-03

    The Titanium Elastic Nail (TEN) offers a number of potential advantages over traditional ways of treating long bone fractures particularly in the paediatric population. These advantages include earlier mobilisation and shorter hospital stay and less risk of loss of fracture position. These advantages are most apparent and significant when treating femoral fractures in children where the length of hospital stay is reduced from several weeks to a typical period of 5 to 8 days. We have reviewed our early experience of using these implants over the past 2 years. Patients were assessed clinically and radiologically. 13 patients were treated using the TEN during this period. There were 2 femoral fractures, 4 humeral fractures, 1 tibial and 6 forearm fractures treated using the Titanium Elastic Nail. All fractures united during the study period. However 1 humeral fracture required a secondary bone grafting and plating for delayed union and 1 fracture lost position during follow-up. Insertion point pain was a problem in 4 patients but this resolved after nail removal in all. There was 1 superficial wound infection which resolved with antibiotics and 1 superficial wound infection of an open fracture wound which resolved following nail removal and antibiotics. There were no cases of deep infection. There were no limb length discrepancy or rotational or angular malalignment problems. Biomechanical principles and technical aspects of this type of fixation are discussed.

    2017-01-01

    Nail psoriasis is considered a significant psychological and social problem causing functional impairment in affected patients. Nail changes hamper their daily and occupational activities and contribute to a worse quality of life. Almost 50% of patients with psoriasis vulgaris and up to 80% of patients with psoriatic arthritis are afflicted with nail lesions. The important correlation between psoriatic arthritis and nail changes is well established - the presence of the latter is a strong predictor of the development of arthritis. There is a broad spectrum of nail dystrophies associated with psoriasis, ranging from the common pitting, subungual hyperkeratosis and loosening of the nail plate to less frequent discolouration and splinter haemorrhages. Some of these symptoms are also observed in other nail diseases, and further diagnostics should be performed. The assessment tools NAPSI (Nail Psoriasis Severity Index), mNAPSI (Modified Nail Psoriasis Severity Index), and PNSS (Psoriasis Nail Severity Score) are most commonly used to grade the severity of nail involvement in psoriasis and enable the evaluation of therapy effectiveness. The treatment of nail psoriasis is a major clinical challenge. It should be adjusted to the extent of dermal, articular and ungual lesions. Systemic therapies of psoriasis, especially biological agents, are most likely to be effective in treating nail psoriasis. However, as their use is limited in scope and safety, topical therapy remains a mainstay, and the combination of corticosteroids and vitamin D3 analogues is considered to be most helpful.

    Unreamed interlocked humeral nailing for stabilisation of acute humeral fractures was introduced a decade ago. Antegrade and retrograde nail insertion are equally popular. The role of nailing as opposed to plating of humeral fractures is the subject of continuous debate. Between 1997 and 2005, 99 acute fractures of the humeral shaft were treated operatively with the unreamed humeral nail (UHN, Synthes) in our Level I Trauma Centre. The mean age of the patients was 63 years. Only eight patients (8.1%) were polytraumatised, nine patients had an open fracture (9.1%), five had a primary radial nerve palsy (5.1%). There were 54 antegrade and 45 retrograde nailings. The procedures were performed by 19 different surgeons, who carefully followed a detailed operation protocol. There were 6 adverse events: 3 secondary radial nerve palsies (3%), 2 fissures at the insertion point (2%) and one false placement of a locking screw (1%). Three patients developed pseudarthrosis (3%). Eight further operation were necessary (8.1%): 3 exploration of the radial nerve, 3 for treatment of pseudarthrosis, one replacement of a locking screw and one wound revision for superficial wound infection. Ninety patients (92 fractures) were evaluated after bone healing. Shoulder function was assessed using the Constant Score, elbow function with the Mayo Elbow Score. 91.3% and 5.4% of patients had an excellent or good shoulder function, 81.5% and 14.1% had an excellent or good elbow function. All patients with a functional deficit of the shoulder joint had antegrade, all patients with a deficit at the elbow joint retrograde nailing. Motor function recovered in all radial nerve palsies. 93.5% of patients had an excellent or good functional end result. Unreamed humeral nailing is a valid therapeutic option for stabilisation of acute humeral shaft fractures. Antegrade and retrograde nailing are associated with specific but different complications. By strictly adhering to the operation technique, the

    2001-01-01

    In this experimental study, the influence of flexible nailing in the later phase of femoral fracture healing was investigated. Sixty rats were randomly assigned to three groups. In 20 rats no intervention was performed, and they served as a control group. Fracture and reamed nailing with a rigid steel nail was performed in the left femur in the other 40 rats. These rats were reoperated after 30 days, and the medullary nail was removed. In one group (20 rats) a flexible polyethylene nail was installed (flexibly nailed group), while the rats in the other group received a steel nail identical to the one that was removed (rigidly nailed group). At 60 and 90 days, the left femurs of 10 animals in each group were studied clinically, radiologically, and biomechanically, and bone mineralization was measured by dual-energy X-ray absorptiometry. Radiographs in two planes revealed a clearly visible fracture line in both intervention groups at 60 days. At 90 days, the fracture line was clearly visible in the flexibly nailed group, while bridging callus was apparent after the rigid nailing. At 60 and 90 days, the callus area in the flexibly nailed group was significantly larger than that in the rigidly nailed bones. Biomechanically, flexible nailing reduced maximum bending load and fracture energy at 60 and 90 days compared with findings in rigidly nailed bones, while bending rigidity was similar in the two groups. All values for biomechanical characteristics were reduced at 60 and 90 days in flexibly nailed bones compared with intact femurs, while in the rigid nailing group, bending load and fracture energy were similar to those in intact bones at 90 days. Bone mineral content in the callus segment and diaphysis was greater in the rigidly nailed bones than in the flexible nailing group at 60 days, while at 90 days, no differences were detected. In conclusion, this animal study indicates that: (1) flexible nailing in the later phase of fracture healing increases callus

    The main difficulties encountered in the orthopedic treatment of leg fractures with intact fibula are reduction of the tibial and an unusually high rate of varus unions and non-unions. The aim of this retrospective study was to assess the outcome after reamed nailing of tibial fractures with an intact fibula. Between 1986 and 1997, 38 fractures of the tibia with an intact fibula were treated by first intention centromedullar nailing. There were 28 men and 10 women, mean age 28 years, with a single fracture in 25 cases. There were 25 motor vehicle accidents (17 two-wheel, 8 four-wheel), 5 sports accidents, 2 home falls, and 6 others. Fracture of the tibial diaphysis was associated with a homolateral femoral fracture in 7 cases, 7 fractures were open (7 type 1, 2 type 2, 1 type 3), 7 fractures were associated with abrasive skin lesions. Using the AO classification, the tibial fracture was type A in 26 cases, type B in 11, and type C in 1. The fracture was in the middle third of the tibia in 21 cases, the distal third in 15 and in the proximal third. Grosse and Kempf nails were used exclusively. Static nailing was used in 27 cases, dynamic nailing in 8, and the nail was not locked in 3 cases. Nails of diameter 9 to 13 were implanted after reaming 1 mm more. The fracture gap increased during the reaming in 5 patients; 2 patients had to undergo a secondary aponeurectomy due to a postoperative compartment syndrome and had no further sequela. Consolidation was achieved after the first intention treatment in 30 patients, after dynamization in 6. A non-union in 2 patients was also successfully managed with new nailing and dynamization. Delay to consolidation was a mean 175 days (range 60 - 480). Transverse fractures consolidated more rapidly (mean 122 days). At last follow-up (minimum 1 year), active knee and ankle mobility were normal in all patients. Nineteen patients complained of pain at the site of the nail insertion, evaluated at 1 on a 10-point analogie scale by 10

    The basic principle of non-surgical fracture treatment is to restore the original anatomical position of fractured fragments by different techniques, without direct access to the bone and without further traumatizing of tissues. Intramedullary nailing is synthesis and consolidation of fracture fragments with the main goal to gain strength and permanent placement of the implants. Two techniques of intramedullary osteosynthesis are used: with dynamic or with static intramedullary nail. Dynamization include conversion of static nail by removing screws from the longest fragment. The aim of this study is to determine whether there is a difference in the speed and quality of healing of the type A and B fractures of the femur and tibia treated by static or dynamic intramedullary nails and to compare the results. The study was conducted at the Clinic for Orthopaedics and Traumatology, Clinical Center University Sarajevo from January 2004 to June 2009. The study was retrospective-prospective, manipulative, controlled and it was conducted on a total of 129 patients with closed fractures of the diaphysis of the femur and tibia type A and type B, with different segments of bone, regardless of sex and age structure, with the exception of children under 14 years of age. Precisely there were 47 patients with femoral fractures and 82 patients with tibial fractures. The average number of weeks of healing femoral and tibial fractures was slightly in advantage of static intramedullary osteosynthesis, it was 17.08 weeks (SD=3.382). The average number of weeks of healing in 23 patients with fractures of the femur, treated by dynamic intramedullary osteosynthesis was 17.83 (SD=2.978). We can conclude that static intramedullary nailing osteosynthesis unable movements between fragments which directly stimulates bone formation and formation of minimal callus. Static intramedullary osteosynthesis resolve the problem of stabilizing the fracture, limb shortening and rotation of fragments.

    Full Text Available Internal fixation with intramedullary devices has gained popularity for the treatment of intertrochanteric femoral fractures, which are common injuries in the elderly. The most common complications are lag screw cut out from the femoral head and femoral fracture at the distal tip of the nail. We report here a rare complication of postoperative lag screw migration into the pelvis with no trauma. The patient was subsequently treated with lag screw removal and revision surgery with total hip arthroplasty. This case demonstrated that optimal fracture reduction and positioning of the lag screw are the most important surgical steps for decreasing the risk of medial migration of the lag screw. Furthermore, to prevent complications, careful attention should be paid to subsequent steps such as precise insertion of the set screw.

    The nail unit is the largest and a rather complex skin appendage. It is located on the dorsal aspect of the tips of fingers and toes and has important protective and sensory functions. Development begins in utero between weeks 7 and 8 and is fully formed at birth. For its correct development, a great number of signals are necessary. Anatomically, it consists of 4 epithelial components: the matrix that forms the nail plate; the nail bed that firmly attaches the plate to the distal phalanx; the hyponychium that forms a natural barrier at the physiological point of separation of the nail from the bed; and the eponychium that represents the undersurface of the proximal nail fold which is responsible for the formation of the cuticle. The connective tissue components of the matrix and nail bed dermis are located between the corresponding epithelia and the bone of the distal phalanx. Characteristics of the connective tissue include: a morphogenetic potency for the regeneration of their epithelia; the lateral and proximal nail folds form a distally open frame for the growing nail; and the tip of the digit has rich sensible and sensory innervation. The blood supply is provided by the paired volar and dorsal digital arteries. Veins and lymphatic vessels are less well defined. The microscopic anatomy varies from nail subregion to subregion. Several different biopsy techniques are available for the histopathological evaluation of nail alterations. ©2015 Frontline Medical Communications.

    Full Text Available Yellow nail syndrome is a rare disease of unclear etiology. We describe a patient who develops yellow nail syndrome, with primary nail and sinus manifestations, shortly after amalgam dental implants. A study of the patient's nail shedding showed elevated nail titanium levels. The patient had her dental implants removed and had complete resolution of her sinus symptoms with no change in her nail findings. Since the patient's nail findings did not resolve we do not believe titanium exposure is a cause of her yellow nail syndrome but perhaps a possible relationship exists between titanium exposure and yellow nail syndrome that requires further studies.

    With the increasing use of nail paints, nail art, acetone, repeated manicures, cosmetic nail procedures and detergents, the nail plate undergoes regular damage resulting in rough, lusterless and pigmented nails. Besides that onychomycosis, nail lichen planus, nail pitting and ridging due to various diseases also cause cosmetically disfiguring nails. The study is directed toward use of 70% glycolic acid for controlled keratolysis of the nail-plate, resulting that could result in shinier, smoother and brighter nails. A prospective single-center open-label uncontrolled study of 31 patients, 22 with dry, rough, discolored nails and 9 with hyperkeratotic nails were included in the study group. After examination and ruling out any infection, petroleum jelly was applied on the cuticle margins of the nails for protection and 70% glycolic acid was applied over the nail plate for 45 minutes. In dry rough discolored nails, only a single sitting was done while in hyper-keratotic nail conditions multiple weekly sittings were done. In 22 patients with dry rough nails, 80% showed good improvement, 10% showed average improvement, whereas 10% were non-responsive. Nine patients with thickened nail plate showed good improvement in 60% average improvement in 25% improvement and 15% were non-responsive, after multiple sessions. Controlled keratolysis of the nail plate with application of 70% glycolic acid can be a promising treatment for modality for thick, uneven, rough and pigmented nail-plate conditions with cosmetically pleasing results.

    2011-01-01

    Treating elderly patients has become common in daily clinical practice. Consequently, it is important to focus our interest on a neglected region: the nail area. Anatomy and physiology are indispensable for a good comprehension of some phenomenons. Histopathology of senile changes may explain some pathologic situations and is indispensable for diagnosing uncommon tumors. Chemical composition shows that a normal nail contains 18% water. The rate of linear nail decreases as age advances. Ridging is a normal finding on fingernails, with color varying from shades of yellow to grey. The most common disorders, however, are linked to repeated trauma, with sometimes ingrowing toenails with different appearances. Tumors in the nail area are relatively frequent. Nail fungal infection may be isolated or associated with conditions such as psoriasis and diabetes. The management of the main nail disorders observed in the elderly are presented.

    The purpose of this study is to compare the clinical effects of our self-designed rotary self-locking intramedullary nail (RSIN) and interlocking intramedullary nail (IIN) for long bone fractures. A retrospective study was performed in 1,704 patients who suffered bone fractures and underwent RSIN or IIN operation in our hospital between March 1999 and March 2013, including 494 with femoral fractures, 572 with humeral fractures, and 638 with tibial fractures. Among them, 634 patients were followed up for more than 1 year. The operative time, intraoperative blood loss, postoperative complications, healing rate, and the excellent and good rate of functional recovery were compared between two groups. Compared with IIN group, RSIN group exhibited significantly shorter operative time and less intraoperative blood loss no matter for humeral, femoral, or tibial fractures (all p fractures (both p fracture. In IIN group, nail breakage or loosening occurred in 7 patients with femoral fractures and 16 patients with tibial fractures, radial nerve injury was observed in 8 patients with humeral fractures, and incision infection was present in 2 patients with humeral fractures and 1 patient with femoral fracture. The complication rate of IIN group was significantly higher than that of RSIN group (p treatment of long bone fractures.

    2013-12-01

    Though augmentation plating (AP) with decortication and bone grafting (BG) reportedly has excellent outcomes for femoral shaft nonunions, there are no established indications of AP with decortication and BG. The purpose of this study was to evaluate the results of AP with decortication and autogenous BG for femoral shaft nonunions, focussing on the indications of AP with decortication and BG. Thirty-nine patients treated with AP combined with decortication and BG for femoral shaft nonunions after femoral nail failure between November 1996 and October 2010 were retrospectively reviewed. Indications of AP with decortication and BG at the time of surgery and outcomes (bony union) were evaluated. The mean follow-up duration was 24.8 months (range 12-81 months). Thirty-eight (97%) of 39 femoral shaft nonunions achieved bony union. One incompliant patient showed screw breakage, which was healed uneventfully with subsequent cast application. The mean time to union was 6.1 months (range 3-16 months). Primary indications at the time of surgery were nonisthmal femoral nonunions in 17 patients, isthmal nonunions in 10 patients (cortical bone defect in five and widened canal in five), failed exchange nail in seven patients, nonunions with malrotation in two patients and difficult removal in three patients. AP with decortication and autogenous BG is a good option for nonisthmal femoral shaft nonunions, such as supra-isthmal and infra-isthmal nonunions. In addition, this option is useful for selected cases of isthmal femoral shaft nonunions in which failure of exchange nailing is expected due to lack of a tight fit between the new larger nail and femoral cortices.

    2017-03-01

    Full Text Available INTRODUCTION: Infected nonunion of long bones is a chronic and debilitating disorder. It is more difficult to deal with when the implant used for internal fixation itself becomes a potential media for infection because of bacterial adhesion and biofilm formation. Traditionally, it is managed by two- stage procedure for controlling the infection first and then treating the nonunion. This study has been undertaken to explore antibiotic cement coated nailing as single stage treatment modality for treating infection and achieving stability at the same time. MATERIALS AND METHODS: Twenty patients (above 18 years age with infected nonunion of tibia with bone gap less than 2 cm were managed using antibiotic cement coated K-nail. Antibiotic cement nail was prepared using endotracheal tube method. Antibiotics used were a combination of vancomycin and teicoplanin. RESULTS: Infection was controlled in 95% of the patients. Bony union was achieved in 12 of 20 (60% patients with antibiotic cement nailing as the only procedure with average time of union of 32 weeks. Remaining 8 patients required additional procedures like bone grafting or exchange nailing and these were done in six patients, with union of fracture. Two patients refused to undergo further procedures. Complications encountered were difficult nail removal in three cases, broken nail in two cases, and bent nail in one case. Recurrence of infection was observed in two patients. Average period of follow-up was 13 months. CONCLUSION: Antibiotic cement impregnated nailing is a simple, economical and effective single stage procedure for the management of infected nonunion of tibia. It is advantageous over external fixators, as it eliminates the complications of external fixators and has good patient compliance. The method utilizes existing easily available instrumentation and materials and is technically less demanding, and therefore can be performed at any general orthopaedic center.

    The nails have a functional and esthetic importance for patients. Almost always, the nail disorders are diagnosed on the basis of clinical findings, but imaging methods may be required for a better assessment. These imaging methods, such as ultrasound and magnetic resonance, may help to establish an accurate diagnosis. Magnetic resonance imaging is not widely available and sometimes may be very expensive; that is why, ultrasound is an excellent imaging modality. Our objective is to expose the nail unit anatomy, the nail unit anatomy in ultrasound, and some of the frequent pathologies found in our daily practice. A review of the literature was done to review the anatomy, technical aspects, and different findings in normal and abnormal nail unit ultrasound. Ultrasound offers an appropriate alternative for the evaluation of the nail unit, allows a real-time evaluation of each one of the components of the nail unit with an optimal visualization of these structures, and allows the evaluation of the thickness of the components, the vascularity, and blood flow by Doppler application. In addition, the nail unit disorder, such as infectious diseases, inflammatory and rheumatologic conditions, nail tumors, among others, may be assessed, not only in the diagnosis but also in the follow-up. Pre-surgical evaluation, surgical follow-up, and some procedures, such as biopsies, may be done by this technique. Ultrasound is an excellent technique for evaluation of normal anatomy, diagnosis, and follow-up of patients with nail unit diseases. This is an alternative for other imaging methods and may be used for an accurate diagnosis approach.

    Full Text Available The yellow nail syndrome is a scarcely described condition characterized by dystrophic yellowish nails, respiratory disturbances and lymphedema; while the pincer nail deformity is characterized by thickening and excessive transverse curvature of the nail plate. The objective of this case study is to report a 76-year-old Japanese descent woman with yellow nail syndrome and pincer nails, intestinal polyps, and sigmoid colon adenocarcinoma. Both the yellow nail syndrome and pincer nails may develop in association with malignancies, either by chance or by some etiopathogenic mechanism not well-known.

    The optimal treatment for slipped capital femoral epiphysis (SCFE) remains controversial. In Sweden, the standard treatment is unthreaded fixation over the physis, with the purpose to permit continued growth of the femoral neck. The aim of the present study was to verify and quantify longitudinal growth of the femoral neck after in situ pinning with the Hansson hook-pin. We performed a retrospective study of 54 patients treated with the Hansson hook-pin for SCFE between 2001 and 2009. The immediate postoperative radiograph and the radiograph after physeal closure (mean interval, 34 mo) were analyzed. Because the smooth Hansson hook-pin only has a grip fixation in the epiphysis, the femoral neck growth was determined as the difference in nail protrusion from the lateral cortex between the 2 radiographs. The femoral neck offset was also measured in all radiographs. Significant longitudinal growth occurred both in the slipped and the prophylactically treated contralateral hip by mean 7.1 mm (Pslip severity (range, 4.0 to 71,6 degrees; mean 27.3 degrees). Young patients (less than 11 y) grew more than older patients (more than 14 y), 12.1 vs. 4.2 mm, P=0.002. The femoral offset increased by mean 16% from mean 30.0 to 35.2 mm (Pfemoral neck correlated with the increase in femoral offset (R=0.51, Pfemoral neck. The remaining growth enables the patient to achieve an almost anatomic offset of the hip. This is essential to optimize the abduction forces that stabilize the pelvis during gait. Future studies need to establish whether the longitudinal growth also results in improved remodelling of the proximal femur. Level III-retrospective comparative study.

  15. Broken Ergodicity in MHD Turbulence

    Shebalin, John V.

    2010-01-01

    Ideal magnetohydrodynamic (MHD) turbulence may be represented by finite Fourier series, where the inherent periodic box serves as a surrogate for a bounded astrophysical plasma. Independent Fourier coefficients form a canonical ensemble described by a Gaussian probability density function containing a Hermitian covariance matrix with positive eigenvalues. The eigenvalues at lowest wave number can be very small, resulting in a large-scale coherent structure: a turbulent dynamo. This is seen in computations and a theoretical explanation in terms of 'broken ergodicity' contains Taylor s theory of force-free states. An important problem for future work is the case of real, i.e., dissipative flows. In real flows, broken ergodicity and coherent structure are still expected to occur in MHD turbulence at the largest scale, as suggested by low resolution simulations. One challenge is to incorporate coherent structure at the largest scale into the theory of turbulent fluctuations at smaller scales.

    The purpose of this study was to investigate the influence of lateral muscle loading on the stress/strain distributions of the trochanteric Gamma nail (TGN) fixation within the healed, trochanteric and subtrochanteric femoral fractures by means of a finite element method. The effect of three muscle groups, the abductors (ABD), the vastus lateralis (VL) and the iliotibial band (ITB), were investigated. The analytical results showed that addition of lateral muscle forces, iliotibial band and vastus lateralis, produced compensation of forces and reduction of bending moments in the bone and in the trochanteric Gamma nail especially in the lateral aspect. The iliotibial band produced a higher impact as compared to the vastus lateralis. Therefore in the finite element analysis of the proximal femur with the trochanteric Gamma nail fracture fixation should include the lateral muscle forces to simulate load condition with maximal physiological relevance to the closed nailing technique.

  18. Medial migration of the intramedullary Gamma 3 nail - a case report

    Directory of Open Access Journals (Sweden)

    Ana Costa Pinheiro

    Full Text Available ABSTRACT Intertrochanteric femur fractures are very common in patients over 65 years old, and are often associated with osteoporosis. Proximal femoral nails are preferred because of their biomechanical advantages in the treatment of these fractures, especially if the fracture is unstable. However, many complications associated with intramedullary fracture fixation have been described. The medial migration of the intramedullary gamma nail is a rare complication. The authors report an uncommon but potentially fatal complication, medial and intrapelvic migration of the intramedullary Gamma 3 nails, recorded after one month of osteosynthesis. This article aims to alert the orthopedic community to this rare complication, which may present a high risk of morbidity and mortality.

    2007-01-01

    We report the case of an infected nonunion of the proximal femoral in an elderly patient. There was extensive involvement of the entire proximal femur precluding salvage. An impromptu use of a cephalomedullary nail coated with antibiotic-laden bone cement is described, followed by reimplantation with a revision-type proximal femoral prosthesis. The patient had resection of the proximal femur, placement of a temporary functional spacer, and reimplantation after a course of antibiotics, with good success. The method we describe is a reasonable alternative when standard off-the-shelf systems or other methods of temporary spacer creation are not available.

    It has been known since the 1940s that nail polishes contain allergenic ingredients. The aim of this study was to clarify whether the nail polishes on the market today contain significant amounts of allergens, and what the solvents are. The following ingredients were determined: toluene, toluene sulfonamide formaldehyde resins, free formaldehyde, acrylates, methacrylates and certain organic solvents. The study comprised 20 brands and 42 samples. All the nail polishes analysed contained allergenic toluene sulfonamide formaldehyde resins (TSFR), in concentrations from 0.08 to 11.0%. The concentration of total formaldehyde varied from 0.02% to 0.5%. The more TSFR a nail polish contained, the higher was its formaldehyde content. Probably not only TSFR-allergic but also formaldehyde-allergic persons may get dermatitis from many of the nail polishes studied. The concentrations of acrylates and methacrylates were so small that they are of practical significance only to those previously sensitized to acrylates. Of the organic solvents, toluene was still widely used, whereas xylene was found in only 1 product. The nail polishes on the market today are not safe for all consumers. However, according to the regulations of the European Union, the packaging labeling of all cosmetic products must be supplied with a list of ingredients from the beginning of 1998. This will help the consumer to avoid allergenic products. A better alternative could, however, be to substitute the most allergenic ingredients with substances possessing minor allergy potency.

    Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes the risk for acute traumatic injury compared to use of a contact actuation trigger (CAT) nail gun. A theoretically-based increased risk of work-related musculoskeletal disorders from use of a SAT nail gun, relative to CAT, appears unlikely and remains unproven. Based on current knowledge, the use of CAT nail guns cannot be justified as a safe alternative to SAT nail guns. This letter provides a perspective of ergonomists and occupational safety researchers recommending the use of the sequential actuation trigger for all nail gun tasks in the construction industry.

    Penetrating limb injuries are common during conflict, and in many there will be an associated fracture. Treatment of ballistic femoral fractures would usually be with by intramedullary nail; however, within the resource-constrained environment during conflict this is rarely possible. This report illustrates what can be achieved at a Role 2 facility to provide skeletal traction with the equipment and skills available. We discuss the history of skeletal traction and its use in ballistic femoral fractures, and believe that skeletal traction is still a valuable technique that we shouldn't ignore. Military surgeons should be able to use skeletal traction to manage ballistic femoral fractures in the spartan environment of a deployed forward hospital.

    The radius of curvature (ROC) misfit of cephalomedullary nails during anterograde nailing can lead to complications such as distal anterior cortical encroachment. This study quantified the anatomical fit of a new nail with 1.0-m ROC (TFN-ADVANCED(™) Proximal Femoral Nailing System [TFNA]) compared with a nail with 1.5-m ROC (Gamma3 Long Nail R1.5 [Gamma3]). We generated 63 three-dimensional models (48 female, 45 right femur) representing the cortical surfaces of the femora (31 Caucasian, 28 Japanese, and 4 Thai). The mean age of the specimens was 77 years (±8.1), and the mean height was 158.5 cm (±9.6). Utilizing a customized software tool, nail fit was determined from the total surface area of nail protrusion from the inner cortex surface and maximum distance of nail protrusion in the axial plane; the position of the distal nail tip within the canal was also determined. Overall, TFNA had both a significantly smaller mean total surface area of nail protrusion (915.8 vs. 1181.6 mm(2); P < 0.05) and a mean maximum distance of nail protrusion in the axial plane (1.9 vs. 2.1 mm; P = 0.007) when compared with Gamma3. The mean total surface area of nail protrusion was significantly smaller with TFNA versus Gamma3 in both the Caucasian (P = 0.0009) and Asian (Japanese and Thai) samples (P = 0.000002); the mean maximum distance of TFNA protrusion was significantly smaller in Asians (P = 0.04), but not in Caucasians (P = 0.08). Most tip positions for both nail types were anterior, but TFNA had a higher number of center positions than Gamma3 (13 vs. 7) and a shift from the far anterior cortex to the center of the medullary canal (overall and in Caucasians). In Asians, the most prominent position was far anterior for both nails. The 1.0-m ROC TFNA nail resulted in better fit than the 1.5-m ROC Gamma3 nail. Clinical trials and case studies should be conducted in the future to verify if these findings would also result in clinical improvements.

    The topical treatment of nail fungal infections has been a focal point of nail research in the past few decades as it offers a much safer and focused alternative to conventional oral therapy. Although the current focus remains on exploring the ways of enhancing permeation through the formidable nail barrier, the understanding of the nail microstructure and composition is far from complete. This article reviews our current understanding of the nail microstructure, composition and diseases. A few of the parameters affecting the nail permeability and potential causes of the recurrence of fungal nail infection are also discussed. © 2017 Blackwell Verlag GmbH.

  14. Reducing intraoperative duration and ionising radiation exposure during the insertion of distal locking screws of intramedullary nails: a small-scale study comparing the current fluoroscopic method against radiation-free, electromagnetic navigation.

    Grimwood, Darren; Harvey-Lloyd, Jane

    2016-12-01

    Intramedullary nailing is the standard surgical treatment for mid-diaphyseal fractures of long bones; however, it is also a high radiation dose procedure. Distal locking is regularly cited as a demanding element of the procedure, and there remains a reliance on X-ray fluoroscopy to locate the distal holes. A recently developed electromagnetic navigation (EMN) system allows radiation-free distal locking, with a virtual on-screen image. To compare operative duration, fluoroscopy time and radiation dose when using EMN over fluoroscopy, for the distal locking of intramedullary nails. Consecutive patients with mid-diaphyseal fractures of the tibia and femur, treatable with intramedullary nails, were prospectively enrolled during a 9-month period. The sample consisted of 29 individuals, 19 under fluoroscopic guidance and 10 utilising EMN. Participants were allocated depending on the type of intramedullary nail used and surgeon's preference. These were further divided into tibial and femoral subcategories, relative to the fracture site. EMN reduced fluoroscopy time by 49 (p = 0.038) and 28 s during tibial and femoral nailings, respectively. Radiation dose was reduced by 18 cGy/cm(2) (p = 0.046) during tibial and 181 cGy/cm(2) during femoral nailings when utilising EMN. Operative duration was 11 min slower during tibial nailings using EMN, but 38 min faster in respect of femoral nailings. This study has evidenced statistically significant reductions in both fluoroscopy time and radiation dose when using EMN for the distal locking of intramedullary nails. It is expected that overall operative duration would also decrease in line with similar studies, with increased usage and a larger sample.

    Nail patella syndrome (NPS) is a skeletal dysplasia with patellofemoral dysfunction as a key symptom. We present the first in-depth radiological evaluation of the knee in a large series of NPS patients and describe the typical malformations. Conventional radiological examination of 95 skeletally mature patients with NPS was performed. Patellar morphology was classified according to the Wiberg classification as modified by Baumgartl and Ficat criteria, and trochlear shape was classified according to the Dejour classification. Patellar aplasia was present in 4/90 (4%), and patellar hypoplasia in 77/90 (86%) of patients. The prevailing patellar shapes were type III, type IV and Hunter's cap. No patellar shape genotype-phenotype association could be found. The malformations of the distal femur comprised shortening of the lateral femoral condyle in 46 out of 84 patients (55%), with a prominent anterior surface of the lateral femoral condyle in 47 out of 84 patients (56%) and a flat anterior surface of the medial femoral condyle in 78 out of 85 patients (92%). The trochlea was type A1 according to the Dejour classification in 79 out of 85 patients (93%). An easily recognisable characteristic quartet of malformations consisting of patellar aplasiaor hypoplasia and the malformations of the distal femur was found in 22 out of 81 patients (27%), with the majority displaying at least three malformations. The distinct malformations of the knee in nail patella syndrome are easily recognisable on conventional radiographs and lead to the correct interpretation of the aberrant morphology which is essential in the treatment of these patellofemoral disorders. ©2016 The British Editorial Society of Bone & Joint Surgery.

  16. Broken Windows and Collective Efficacy

    Directory of Open Access Journals (Sweden)

    Aldrin Abdullah

    2015-01-01

    Full Text Available The broken windows thesis posits that signs of disorder increase crime and fear, both directly and indirectly. Although considerable theoretical evidence exists to support the idea that disorder is positively related to fear of crime, the empirical literature on examining the indirect effect of the individual’s perception of incivilities on fear of crime is limited, especially in developing countries. This research was conducted to assess the indirect relationship between perceived disorder and fear of crime through collective efficacy. A total of 235 households from Penang, Malaysia, participated in this study. Results reveal that high perception of disorder is negatively associated with collective efficacy. High collective efficacy is associated with low fear of crime. Moreover, a significant and indirect effect of disorder on fear of crime exists through collective efficacy. The results provide empirical support for the broken windows theory in the Malaysian context and suggest that both environmental conditions and interactions of residents play a role in the perceived fear of crime.

    Full Text Available Nail psoriasis, affecting up to 50% of psoriatic patients, is an important cause of serious psychological and physical distress. Traditional treatments for nail psoriasis, which include topical or intralesional corticosteroids, topical vitamin D analogues, photochemotherapy, oral retinoids, methotrexate, and cyclosporin, can be time-consuming, painful, or limited by significant toxicities. Biological agents may have the potential to revolutionize the management of patients with disabling nail psoriasis. We present another case of disabling nail psoriasis that responded dramatically to infliximab.

    Recent reports have raised concerns about low-energy subtrochanteric and diaphyseal femoral fractures after long-term bisphosphonate treatment, which may be associated with severely suppressed bone turnover (SSBT). However, diaphyseal femoral fractures without bisphosphonate treatment have also been reported in patients with severely curved femur, which are commonplace in the elderly. The purpose of this study was therefore to investigate associations between occurrence of such fractures, bisphosphonate use, and curvature of the femur. Nine consecutive elderly patients treated for low-energy diaphyseal femoral fractures between 2005 and 2010 were retrospectively reviewed. Three patients sustained bilateral fractures. Eight patients were administered bisphosphonates and one patient was administered raloxifene. Duration of osteoporosis treatment, type of fractures, surgical procedure, cortical thickness and curvature of opposite femur were evaluated. The cortical thickness and femoral curvature were further compared with those of 24 control subjects without fractures. The mean duration of drug administration was 3.6 years. All fractures showed similar X-ray patterns of simple transverse fracture with medial spike. Only one femur showed thickening of the femoral cortex. One case was treated with locking plate fixation, while the other cases were operated with intramedullary nails (9 antegrade nails, 2 retrograde nails). One femur treated with retrograde nail showed delayed bone union. The femoral curvature was significantly higher in the low-energy fracture group than the control group (P < 0.01); however, cortical thickness did not show a significant difference between the groups. In addition to SSBT, increased femoral curvature might be a causative factor for low-energy diaphyseal femoral fracture in the elderly.

    Full Text Available Background: Femoral bowing plane (FBP is the unattended subject in the literature. More over the femoral shaft with its bowing is neglected in established anteversion determination methods. There is limited information about the relationship between FBP and anteversion. Thus we focused on this subject and hypothesized that there could be an adaptation of FBP to anteversion. Materials and Methods: FBP is determined on three-dimensional solid models derived from the left femoral computerized tomography data of 47 patients which were taken before for another reason and comparatively evaluated with anteversion. There were 20 women and 27 men. The mean age of patients was 56 years (range 21-84 years. Results: The anteversion values were found as the angle between a distal condylar axis (DCA and femoral neck anteversion axis (FNAA along an imaginary longitudinal femoral axis (LFA in the true cranio-caudal view. The FBP was determined as a plane that passes through the centre-points of three pre-determinated sections on the femoral shaft. The angles between DCA, FNAA and FBP were comparatively evaluated. The independent samples t-test was used for statistical analysis. At the end, it was found that FBP lies nearly perpendicular to the anteversion axis for the mean of our sample which is around 89° in females and 93° in males (range 78-102°. On the other hand, FBP does not lie close to the sagittal femoral plane (SFP; instead, there is an average 12.5° external rotation relative to the SFP. FBP is correlated well with anteversion in terms of FBP inclination from SFP and femoral torsion (i.e., angle between FBP and femoral neck anteversion axis (P0 < 0.001; r = 0.680 and r = −0.682, respectively. Combined correlation is perfect (R[2] = 1 as the FBP, SFP, and posterior femoral plane forms a triangle in the cranio-caudal view. Conclusions: We found that FBP adapts to anteversion. As FBP lies close to perpendicularity for the mean, femoral component

    MicroRNA levels in sera or hair may potentially be useful biomarkers for various diseases. The diagnosis of nail diseases is sometimes difficult, and nail psoriasis without skin lesions is indistinguishable from nail changes caused by other diseases. We evaluated nail microRNA levels as biomarkers for the diagnosis of psoriasis patients. MicroRNA levels were examined in psoriasis patients with (11 patients) and without (six patients) nail changes. Normal control nails were collected from 17 healthy subjects. Eight patients with other diseases who also had nail changes were also included as disease controls. Microarray, real-time PCR, and in situ hybridisation indicated that the expression levels of nail miR-4454 were decreased in psoriasis patients with nail changes, compared to those patients with other diseases involving nail change, or healthy subjects. The miR-4454 levels in nails showed a significant inverse correlation with the Nail Psoriasis Severity Index (NAPSI) score, suggesting that nail miR-4454 levels reflect nail condition. The levels of microRNAs in nails may be suitable biomarkers for diagnosis or evaluation of disease activity of psoriasis.

    Impingement and penetration of the anterior cortex of the femur have been reported as complications after cephalomedullary nailing. The purpose of this study was to determine factors related to nail impingement in our population of Hispanic patients. A non-matched case-control study was carried out and 156 patients who underwent cephalomedullary nailing from 2010 and 2013 were included; 78 cases with anterior cortical impingement and 78 control cases without impingement were documented. Demographic variables and specifications of the nails such as manufacture and radius of curvature were recorded. The presence of impingement, angle of incidence on radiographs--indirect measurement of the femoral bow on the sagittal plane--and nail entry site were determined. Bivariate and multivariate logistic regression analyses were performed to identify the factors associated with cortical impingement. The distribution by sex corresponded to 87 females (56%) and 69 males (44%) with a mean age of 75 years [SD 18.2]. Cortical impingement was presented in 78 cases (50%) and 6 (3.8%) patients evidenced penetration of the anterior cortex of the femur. On the bivariate analysis the posterior nail start site is highlighted, which showed a positive association with impingement (OR 4.3; 95% CI 1.1-36 and p = 0.04). After the multivariate analysis, the factors associated with anterior cortical impingement included female gender (OR 2.2; 95 % CI 1.1-4.6 and p ≤ 0.038), straight nails-short nails-(OR 4.9; 95% CI 2.2-10 and p ≤ 0.001) and angle of incidence ≥7° (OR 4.9; 95% CI 2.2-10 and p ≤ 0.001), the latter showing a likelihood of 57 % for impingement, increasing to 90% with an angle of incidence of 11°. Posterior entry site should be avoided and an anterior site should be used. Female gender, straight nails and greater angle of incidence of the femur were associated with cortical impingement. A specific intramedullary nail design is needed for the Hispanic population due to

    Full Text Available Background and Objectives: Diaphyseal femur fracture is one of the commonest fractures to present in an emergency room. The objective of the study was to compare femoral shaft fractures treated using nail with those using plate and screws. Patients and Methods: We studied a total of 62 patients of fracture shaft of femur admitted in the Bharatpur Hospital, Bharatpur, Chitwan and National Academy of Medical Sciences, BirHospital,Kathmandu. Two cases were lost to follow up. Thirty cases were treated with plating and 30 cases with nailing. The age group was from 16-30 years. Fifty-three were male and seven were females. Fifty-eight patients had closed fracture and two had Gustillo Anderson grade I openfracture. Result: Time from injury to surgery was 19 days on an average. Mean time for union was more in patients treated by plating, 19.46 weeks as compared to nailing 14.78 weeks. We found one case of infection with plating and breakage of plate in four patients. One patient with nailing did not show any signs of healing and two had failure in case of nailing. Our series revealed 23(38.3% excellent, five (8.3% good and two (3.3% poor results in patients who had nailing while 15 (25.5% excellent, nine (15% good, one (1.7% fair and five (8.3% poor in patients who had plating out of 30 patients in each group. Conclusion:In our study we found that there was no significant difference in outcomes between plating and intramedullary nailing of femoral diaphysis fracture in terms of union, infection and implant failure.JCMS Nepal. 2016;12(2:66-9.

    intramedullary nailing may reduce recovery time. There is insufficient evidence from comparisons of different methods of conservative treatment or of different methods of surgical treatment to draw conclusions on the relative effects of the treatments compared in the included trials. Different methods of treating fractures of the shaft of the thigh bone in children and adolescents Although uncommon, fractures of the femoral shaft (thigh bone) in children may require prolonged treatment in hospital and sometimes surgery. This can cause significant discomfort and can disrupt the lives of the children and their familles. This review compared different methods of treating these fractures. Surgical treatment comprises different methods of fixing the broken bones, such as internally-placed nails, or pins incorporated into an external frame (external fixation). Non-surgical or conservative treatment usually involves different types of plaster casts with or without traction (where a pulling force is applied to the leg). We searched for studies in the medical literature until August 2013. The review includes 10 randomised or quasi-randomised controlled trials that recruited 527 children. Four trials compared different surgical versus non-surgical treatments; three compared different methods of non-surgical treatment and three compared different methods of surgical treatment. Generally we are unsure about the results of these trials because some were at risk of bias, some results were contradictory and usually there was too little evidence to rule out chance findings. Most trials failed to report on self-assessed function or when children resumed their usual activities. Comparing surgical versus non-surgical treatment. Low quality evidence (one trial, 101 children) showed children had similar function at two years after having surgery, involving external fixation, compared with those treated with a plaster cast. The other three trials did not report this outcome. There was moderate

    Topical drug delivery to treat nail diseases such as onychomycosis and psoriasis is receiving increasing attention. Topical nail delivery is challenged by the complicated structure of the nail and the low permeability of most drugs across the nail plate. Considerable effort has been directed at developing methods to promote drug permeation across the nail plate. Iontophoresis efficiently enhances molecular transport across the skin and the eye and is now being tested for its potential in ungual delivery. This review covers the basic mechanisms of transport (electro-osmosis and -migration) and their relative contribution to nail iontophoresis as well as the key factors governing nail permselectivity and ionic transport numbers. Methodological issues concerning research in this area are summarized. The data available in vivo on nail iontophoresis of terbinafine specifically are reviewed in separate sections. Our understanding of nail iontophoresis has improved considerably since 2007; most decisively, the feasibility of nail iontophoresis in vivo has been clearly demonstrated. Future work is required to establish the adequate implementation of the technique so that its clinical efficacy to treat onychomycosis and nail psoriasis can be unequivocally determined.

    Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (pvitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study.

    For those interested in nails, a fairly good knowledge of the anatomy of the nail unit is indispensable. But nothing will replace a careful, clinical examination of the nail apparatus. The shape of the nail, surface abnormalities and coloration, with or without a magnifying glass, may well provide a medical diagnosis not only in dermatology but also for medicine in general. Pits on the surface of the nail plate may be enough to diagnose psoriasis on a limited area of scalp dandruff. Even partial detachment of the nail apparatus might lead to the suspicion of psoriatic arthritis. A triangular lunula is associated with the absence of patellas. Finally, no pulmonary examination of a smoker is complete without looking for clubbing. It is high time to pay tribute to the nail. Copyright © 2014. Published by Elsevier Masson SAS.

    Recent studies of mice with hair defects have resulted in major contributions to the understanding of hair disorders. To use mouse models as a tool to study nail diseases, a basic understanding of the similarities and differences between the human and mouse nail unit is required. In this study we compare the human and mouse nail unit at the macroscopic and microscopic level and use immunohistochemistry to determine the keratin expression patterns in the mouse nail unit. Both species have a proximal nail fold, cuticle, nail matrix, nail bed, nail plate, and hyponychium. Distinguishing features are the shape of the nail and the presence of an extended hyponychium in the mouse. Expression patterns of most keratins are similar. These findings indicate that the mouse nail unit shares major characteristics with the human nail unit and overall represents a very similar structure, useful for the investigation of nail diseases and nail biology.

    Nail coatings which harden upon evaporation and coatings that polymerize may produce some reactions at the site of application to the nail itself, and distant reactions when small amounts of nail cosmetics are transferred by the hand to other areas of the skin. Nail cosmetic hazards may be occupational, or accidental, especially in children. Individuals wearing artificial nails tend to wear their nails longer, and are more careful about their nails when washing their hands. The sanitary conditions for the application of artificial nails are therefore paramount in preventing nail infections.

    To report seven cases of broken bioabsorbable femoral crosspins identified by MRI in evaluation of hamstring grafts of the anterior cruciate ligament. Seven cases of broken bioabsorbable crosspins utilized in femoral fixation of ACL hamstring grafts were identified prospectively and retrospectively from our PACs database during a period from 9/1/08 to 8/31/09. All imaging was performed using 1.5 or 3.0 Tesla MRI and were evaluated for T2 signal within and surrounding the crosspin, osteolysis surrounding the fragments, displacement of fragments, and graft integrity. Time from surgery was also recorded. Seven cases of hamstring grafts with broken bioabsorbable crosspins were imaged 4 months to 3 years following grafting. There was osteolysis surrounding the crosspin in all but one case in which the graft was intact but a pin fragment was displaced into the joint. One graft failed due to aseptic foreign-body reaction to the fixation with aggressive osteolysis at 9 months post surgery. In the remaining five, the ACL graft was either completely torn, partially torn, lax, or degenerative and frayed. Of these, the crosspins were broken and angulated with osteolysis surrounding the apex of the angulated fragment or demonstrated lateral extrusion of the peripheral fragment. Bioabsorbable crosspins utilized in femoral fixation of hamstring graft reconstruction of the ACL may become fractured. While the natural history of osteo-integration of these devices as demonstrated by MRI has not been defined, osteolysis surrounding the fragments, extrusion or displacement of the fragments, and graft laxity or failure would suggest that these are abnormal findings that should be reported.

    Femoral stiffness toward torsion and axial thrust of 21 femoral preparations after variety of osteosynthesis for supratrochanteric osteotomy is presented. All the femora were obtained at autopsy from patients 65 years old or older. Bone mineral density was evaluated radiographically and by dual energy X-ray absorptiometry. Osteotomy site was stabilized with screws, angular plates, Zespol hip fixator and Ender nails. No correlation between stiffness toward torsion and against axial load was found. The greatest torsional stiffness was found in non-osteoporotic preparations fixed with Ender nails, Zespol hip fixator and AO plate with compression screw. The last fixation proved most resistant against axial load.

    Full Text Available ABSTRACTOBJECTIVE: To perform a retrospective radiographic evaluation on the fracture reduction and implant position in the femoral head among patients with pertrochanteric fractures who had been treated using a cephalomedullary nail in lateral decubitus; and to assess factors that might interfere with the quality of the fracture reduction and with the implant position in using this technique. METHODS: Nineteen patients with a diagnosis of pertrochanteric fractures of the femur who had been treated using cephalomedullary nails in lateral decubitus were evaluated. For outpatient radiographic evaluations, we used the anteroposterior view of the pelvis and lateral view of the side affected. We measured the cervicodiaphyseal angle, tip-apex distance (TAD, spatial position of the cephalic element in relation to the head, and the bispinal diameter. To make an anthropometric assessment, we used the body mass index. Two groups of patients were created: one in which all the criteria were normal (TAD ≤25 mm, cervicodiaphyseal angle between 130° and 135° and cephalic implant position in the femoral head in the central-central quadrant; and another group presenting alterations in some of the criteria for best prognosis. RESULTS: Female patients predominated (57.9% and the mean age was 60 years. Seven patients presented a central-central cephalic implant position. One patient present a cervicodiaphyseal angle >135° and the maximum TAD was 32 mm; consequently, 12 patients presented some altered criteria (63.2%. None of the characteristics evaluated differed between the patients with all their criteria normal and those with some altered criteria, or showed any statistically significant association among them ( p> 0.05. CONCLUSION: The technique described here enabled good reduction and good positioning of the implant, independent of the anthropometric indices and type of fracture.

    Black nails caused by Proteus mirabilis were seen in a motor mechanic and in a petrol pump attendant. Proteus mirabilis is a gram-negative bacillus that generates hydrogen sulfide. This compound reacts with traces of metals in the nail plate such as zinc, nickel, cobalt, iron, manganese, tin, copper and lead. Metal sulfides blacken the nail plate. The protracted course of the discoloration over months corresponds to the slow reactions of metals with hydrogen sulfide. The disappearance of the blackening after topical treatment with chinosol, tincture of iodine and chloramphenicol solution supports the etiologic connection between black nails and Proteus mirabilis. Wet and dirty work encourages the colonisation of Proteus mirabilis between nail fold and nail plate.

    The supergraph technique for calculations in supersymmetric gauge theories where supersymmetry is broken in a "soft" way (without introducing quadratic divergencies) is reviewed. By introducing an external spurion field the set of Feynman rules is formulated and explicit connections between the UV counterterms of a softly broken and rigid SUSY theories are found. It is shown that the renormalization constants of softly broken SUSY gauge theory also become external superfields depending on the spurion field. Their explicit form repeats that of the constants of a rigid theory with the redefinition of the couplings. The method allows us to reproduce all known results on the renormalization of soft couplings and masses in a softly broken theory. As an example the renormalization group functions for soft couplings and masses in the Minimal Supersymmetric Standard Model up to the three-loop level are calculated.

    Full Text Available Nail tic disorders are classic examples of overlap between the domains of dermatology and psychiatry. They are examples of body-focused repetitive behaviors in which there is an irresistible urge or impulse to perform a certain behavior. The behavior is reinforced as it results in some degree of relief and pleasure. Nail tic disorders are common, yet poorly studied and understood. The literature on nail tic disorders is relatively scarce. Common nail tics include nail biting or onychophagia, onychotillomania and the habit tic deformity. Some uncommon and rare nail tic disorders are onychoteiromania, onychotemnomania, onychodaknomania and bidet nails. Onychophagia is chronic nail biting behavior which usually starts during childhood. It is often regarded as a tension reducing measure. Onychotillomania is recurrent picking and manicuring of the fingernails and/or toenails. In severe cases, it may lead to onychoatrophy due to irreversible scarring of the nail matrix. Very often, they occur in psychologically normal children but may sometimes be associated with anxiety. In severe cases, onychotillomania may be an expression of obsessive-compulsive disorders. Management of nail tic disorders is challenging. Frequent applications of distasteful topical preparations on the nail and periungual skin can discourage patients from biting and chewing their fingernails. Habit-tic deformity can be helped by bandaging the digit daily with permeable adhesive tape. Fluoxetine in high doses can be helpful in interrupting these compulsive disorders in adults. For a complete diagnosis and accurate management, it is imperative to assess the patient's mental health and simultaneously treat the underlying psychiatric comorbidity, if any.

    Nail dermoscopy is becoming more and more frequently utilized for the diagnosis of nail disorders. It can be performed with handy dermoscope or with a video dermoscope, which allows magnifications of up to 200. Nail dermoscopy requires a good knowledge of nail anatomy and physiology and the pathogenesis of nail diseases: we have to know which part of the nail we have to look at! The nail is in fact not visible as a whole at one time, but its different parts should be observed, moving the lens back and forth and transversally. All nail disorders can be observed by dermoscopy. However, except for some diseases in which the technique really adds a lot to clinical examination, in most of the cases, nail dermoscopy only permits a better visualization of symptoms already evident to the naked eye. Dermoscopic features of nail signs are always very interesting and surprising, and may help in our understanding of nails. © 2012 Wiley Periodicals, Inc.

    Cephalomedullary nail (CMN) failure is a rare entity following hip fracture treatment. However, it poses significant challenges for revision surgery, both mechanically and biologically. Nail failure rates have been reported at failure, compared to "adequate" and "good" (p = 0.027). Tip-Apex Distance (TAD) mean was 23.2 ± 8.3 mm, and an adequate TAD with three-point fixation was seen in only 35% of cases. Mean time to failure was 401.0 ± 237.2 days, with mean age at failure of 74.0 ± 14.8 years. Options after failure included revision CMN nail, proximal femoral locking plate (PFLP), long-stem or restoration arthroplasty, or femoral endoprosthesis. Barthel Functional Index scores showed no significant difference at 3 and 12 months post-operatively, nor any difference between treatment groups. Mean 12-month mortality was 30%, akin to a primary hip fracture mortality risk according to NICE guidelines. Mortality rates were lowest in revision nails. Subsequent revision rates were higher in the PFLP group. There is no reported evidence on the best surgical technique for managing the failed CMN, with no clear functional benefit in the options above. Good surgical technique at the time of primary CMN surgery is critical in minimising fatigue failure. After revision, overall mortality rates were equivalent to reported primary hip fracture mortality rates. Further multicentre evaluations are required to assess which technique convey the best functional outcomes without compromising 12-month mortality rates.

    The purpose of this study is to assess the need to lock the Gamma 3 nail (Stryker, Mahwah New Jersey USA) distally for intertrochanteric fractures of femur 31-A1 and 31-A2 of the AO. Details were recorded on a sample of 177 patients with intertrochanteric femoral fractures treated in our hospital by a standard Gamma nail between June 2011 and January 2013. A prospective study was conducted by randomizing patients by year of birth, even numbers with, or odd number without, distal locking, forming two groups of 90 and 87 fractures, respectively. The patients treated with a distal locking nail had an increased incidence of medical complications, a lower incidence of biomechanical complications, and an increase in the fracture collapse compared with the control group, with statistical significance (p < 0.05). It is also observed in the group with distal locking increased transfusion requirement and a higher death rate, with statistically significant differences (p < 0.05), but this significance disappears when adjusting for other patient-related characteristics. Based on the results found in this work, the use of distal locking screw in the Gamma 3 nails should be restricted to unstable trochanteric fractures after reduction where additional stability to the intramedullary nail is required, and may decrease the risk of complications from use.

    2014-08-01

    Nail diseases in infants and children are an uncommon cause of consultation and are often difficult to diagnose and to manage. This review will cover nail diseases that are most commonly seen in clinical practice, including congenital and hereditary disorders and inflammatory, infective, and neoplastic nail diseases. The purpose of the review is to help the reader to recognize nail disorders at an early age and to manage them appropriately. Two recent large studies have reported the clinical findings of genetic disorders involving the nails, that is, pachyonychia congenita and epidermolysis bullosa. Only a few articles gave a comprehensive review of a disease, as occurred for onychomycosis, while the majority of the reports published in the recent literature involve single cases. Nail diseases in children and neonates are not easy to diagnose by nonexperts. Basic knowledge of the anatomy and biology of the nail facilitates their diagnosis as the understanding of their pathophysiology. This review gives hints at the most common nail diseases that affect infants and children.

  19. Contact Sensitization to Allergens in Nail Cosmetics.

    Science.gov (United States)

    Chou, Margaret; Dhingra, Nikhil; Strugar, Tamara Lazic

    Ingredients found in the nail cosmetic industry, including but not limited to methacrylate and acrylate monomers, formaldehyde, and toluene sulfonamide-formaldehyde resin, can incite allergic contact dermatitis. An eczematous outbreak presents on areas surrounding the nail plate and may spread through contact transfer of the allergen, commonly to the face and neck. Even components that were originally deemed nonsensitizing, such as the ubiquitous cyanoacrylate adhesive family, have been found to be allergenic. They do not, however, cross-react with methacrylates and acrylates. Alternative options for individuals with allergic contact dermatitis reactions to these ingredients can be avoidance of these procedures or use of products that are "3, 4, 5 free" in which the common allergens dibutyl phthalate, toluene, and formaldehyde are absent. In cases where strengthening of the nail is the sole purpose, nail wraps or preformed nails can be applied for non-cyanoacrylate-sensitive individuals.

  20. Nail changes and disorders among the elderly

    2005-01-01

    Full Text Available Nail disorders are frequent among the geriatric population. This is due in part to the impaired circulation and in particular, susceptibility of the senile nail to fungal infections, faulty biomechanics, neoplasms, concurrent dermatological or systemic diseases, and related treatments. With aging, the rate of growth, color, contour, surface, thickness, chemical composition and histology of the nail unit change. Age associated disorders include brittle nails, trachyonychia, onychauxis, pachyonychia, onychogryphosis, onychophosis, onychoclavus, onychocryptosis, onycholysis, infections, infestations, splinter hemorrhages, subungual hematoma, subungual exostosis and malignancies. Awareness of the symptoms, signs and treatment options for these changes and disorders will enable us to assess and manage the conditions involving the nails of this large and growing segment of the population in a better way.

    2014-01-01

    Limb lengthening and deformity correction with fully implantable systems is becoming more and more widespread. Different actuation techniques are known and every system has its specific limitations in distraction control and/or stability. A new system with magnetic actuation offers outstanding options. The mechanism of the Phenix M2(®) bone lengthening nail (Phenix Medical, France) is driven by a strong external magnet. The device can provide lengthening, shortening and bone transport. Between December 2011 and November 2012 we applied the nail in 10 patients with an average age of 25 years (range 15-40 years). There were 6 femoral and 4 tibial procedures. The intended distraction goal was achieved in 8 of 10 patients. In three cases we simultaneously corrected malalignment. Average lengthening was 4.6 cm (range 1.3-7.6 cm). Average distraction index was 0.85 mm/day (range 0.6-1.3mm/day). Average weight bearing index was 27 days/cm (range 16-37 days/cm). Three patients had revisions due to early distraction arrest. The early results are comparable to those of other intramedullary systems in the literature like the ISKD(®), the Albizzia(®) or the Fitbone(®) system. All intramedullary procedures require accurate analysis and planning, advanced operative technique and close follow-up. The custom made design of the Phenix nail with unique options for size, stroke and locking provides new options for small bones and improved stability. The shortening option may be helpful for soft tissue problems, joint subluxation and additional stimulation of bone formation. Magnetic forces have to be considered and too much soft tissue around the nail might be a limiting factor. The magnetically actuated Phenix nail offers new therapeutic options in limb lengthening.

    2015-09-01

    Acrylic nails, including sculptured nails and the new ultraviolet-curable gel polish lacquers, have been associated with allergic contact dermatitis (ACD). We report 2 cases of ACD to acrylic nails with severe onychodystrophy and psoriasiform changes including onycholysis and subungual hyperkeratosis. In both cases, the patients did not realize the association between the use of acrylate-based manicures and nail changes. One patient had been previously misdiagnosed and treated unsuccessfully for nail psoriasis. The informed clinician should elicit a history of acrylic manicure in patients with these nail changes, especially in cases of suspected nail psoriasis refractory to treatment. Patch testing is a useful tool in confirming diagnosis.

  6. Open intramedullary nailing for segmental long bone fractures: An effective alternative in a resource-restricted environment

    Directory of Open Access Journals (Sweden)

    Olasunkanmi M Babalola

    2016-01-01

    Full Text Available Background: Closed, locked intramedullary nailing has been accepted as the gold standard in the care of femoral fractures, with reported union rates as high as 98-100%. Closed, locked intramedullary nailing often requires expensive equipment which is a challenge in developing countries. Segmental long bone fractures are often a result of high-energy trauma and hence often associated with a lot of injuries to the surrounding soft tissues. This consequently results in higher rates of delayed or nonunion. This study was proposed to review the outcome of management of segmental fractures with locked intramedullary nails, using an open method of reduction. Methods: A retrospective analysis was made of data obtained from all segmental long bone fractures treated with intramedullary nailing over a 1-year period. Records were retrieved from the folders of patients operated on from January 2011 to December 2011. Patients were followed up for a minimum of 1 year after the surgery. Results: We managed a total of 12 segmental long bone fractures in 11 patients. Eight of the 12 fractures were femoral fractures and 10 of the fractures were closed fractures. All but one fracture (91.7% achieved union within 4 months with no major complications. Conclusions: Open method of locked intramedullary nailing achieves satisfactory results when used for the management of long bone fractures. The method can be used for segmental fractures of the humerus, femur, and tibia, with high union rates. This is particularly useful in low-income societies where the use of intraoperative imaging may be unavailable or unaffordable. It gives patients in such societies, a chance for comparable outcomes in terms of union rates as well as avoidance of major complications. Larger prospective studies will be necessary to conclusively validate the efficacy of this fixation method in this environment.

    Slipped capital femoral epiphysis (SCFE) is characterized by displacement of the capital femoral epiphysis from the metaphysis through the physis. The term is confusing, because the metaphysis moves upward and outward while the epiphysis remains in the acetabulum. The SCFE is considered stable when the child is able to walk with or without crutches, and it is considered unstable when the child cannot walk with or without crutches. Patients with SCFE present with pain in the groin, knee and limp. The current treatment of stable SCFE is in situ stabilization with a single screw. Copyright © 2012 SECOT.

    Abadi, Danielle; Zderic, Vesna

    2011-12-01

    A novel ultrasound-mediated drug delivery system has been developed for treatment of a nail fungal disorder (onychomycosis) by improving delivery to the nail bed using ultrasound to increase the permeability of the nail. The slip-in device consists of ultrasound transducers and drug delivery compartments above each toenail. The device is connected to a computer, where a software interface allows users to select their preferred course of treatment. In in vitro testing, canine nails were exposed to 3 energy levels (acoustic power of 1.2 W and exposure durations of 30, 60, and 120 seconds). A stereo -microscope was used to determine how much of a drug-mimicking compound was delivered through the nail layers by measuring brightness on the cross section of each nail tested at each condition, where brightness level decreases coincide with increases in permeability. Each of the 3 energy levels tested showed statistical significance when compared to the control (P permeability factor of 1.3 after 30 seconds of exposure, 1.3 after 60 seconds, and 1.5 after 120 seconds, where a permeability factor of 1 shows no increase in permeability. Current treatments for onychomycosis include systemic, topical, and surgical. Even when used all together, these treatments typically take a long time to result in nail healing, thus making this ultrasound-mediated device a promising alternative.

    Chemicals that may cause allergy are being used in structure nails. In this case report two structure nail makers are described, who were diagnosed with occupational asthma in clinical studies. The studies included an inhalational exposure simulating the work. The causative agents of occupational asthma are apparently the acrylate compounds contained in the chemicals; use of these compounds has previously been linked with allergic contact dermatitis and asthma. Since the making of structure nails involves health risks, such work requires appropriate premises and personal protection.

    AIMS AND OBJECTIVES - Pulse oximetry is mandatory during anaesthesia, sedation and transfer of critically ill patients. The effect of nail polish and acrylic nails on the accuracy of saturation reading is inconsistent. The Lifebox pulse oximeter is reliable and recommended for low and middle income countries. We investigated its accuracy in the presence of 4 nail colours and acrylic nails SUBJECTS AND METHODS Fifty non-smoking volunteers had their fingers numbered from right to left (little finger of right hand =1 and little finger of left hand =10). Alternate fingers were nails painted with clear, red, brown and black nail polish and the 5th finger had acrylic nail applied. The corresponding finger on the other hand acted as control. The oxygen saturation was determined using the Lifebox pulse oximeter. Results All fingers (100%) with clear nail polish, red nail polish and acrylic nails recorded a saturation value. Each of the mean saturation value for clear nail polish, red nail polish and acrylic nails was not significantly different from the control mean (p= 0.378, 0.427 and 0.921). Only 12% and 64% of nails polished black and brown respectively recorded a saturation value. The mean SpO- for black and brown polish were significantly different from their control mean (ppolish resulted in a significant decrease in SpO with the Lifebox oximeter. Dark coloured nail polish should be removed prior to SpO2 determination to ensure that accurate readings can be obtained.

    The study aimed at finding whether there are any nail changes specific to treatment in clubfoot. Sixty new, 26 undergoing serial corrective casting, and 247 clubfoot patients using foot abduction braces were prospectively studied. The casted and braced group formed the basis of the study to observe nail changes, if any. The new patients and opposite normal foot (in unilateral casted cases) were taken as controls. Acute paronychia, ingrown toe nail, onychoshizia, onychorrhexis, nail plate concavity, latent onychomadesis, and distal onycholysis were observed in feet undergoing corrective casting and bracing. Micronychia, malalignment and thinning of nail plate were the observed congenital nail anomalies. Nail changes in clubfeet are not infrequent. Certain nail changes might be etiologically linked to casting and bracing. Some of nail changes might require urgent medical care. Copyright © 2015 European Foot and Ankle Society.

    Reports of yellow nail syndrome have been few and far between. The classical triad of the syndrome has not been reported in Indian literature. We report a case of yellow nail syndrome in a forty-year-old male, who had yellowish-brown nails from birth. He developed lymphoedema of the legs at the age of twenty years and presented with pleural effusion at the age of forty years. Although a case of yellow nail syndrome has been reported from India, the classical triad of the syndrome is yet to be documented from our country. The condition may be missed because of the long time difference in presentation of different components of the syndrome and also because of the dark skin colour of Indians.

    2013-04-01

    Full Text Available Background: Both pelvic fractures and femoral shaft fractures are caused by high-energy injuries. When unstable pelvic fractures and femoral shaft fractures occur concomitantly, the optimal treatment method is controversial. The aim of this study was to establish a reasonable principle for treating such complicated injuries. Methods: Forty patients sustaining unstable pelvic fractures and concomitant femoral shaft fractures were treated in a 7-year period. The initial management of the fractures was started at the emergency service according to the Advanced Trauma Life Support protocol. Unstable pelvic fractures were wrapped by cloth sheets and femoral shaft fractures were immobilized with a splint. Angiography was performed on patients with unstable hemodynamic status. The definitive treatment for combined fractures was performed after stabilizing the hemodynamics. Closed nailing was used for femoral shaft fractures, and pelvic fractures were treated with various techniques. Results: The mortality rate was 12.5% (5/40 during admission. Thirty-three patients were followed up for an average of 32 months (range, 12-76 months. There were 33 cases of unstable pelvic fractures and 36 instances of femoral shaft fractures. The union rate for pelvic fractures was 100% (33/33, while femoral shaft fractures had a 94.4% (34/36 union rate. The average healing time was 3.3 months (range, 1.6-8.1 months and 4.1 months (range, 2.5-18.2 months for pelvic and femoral shaft fractures, respectively. After fracture, 34 hips (94% achieved a satisfactory result in the Harris hip score and 30 knees (83% achieved a satisfactory result in the Mize knee score. Conclusions: Stabilization of the hemodynamics in patients with combined fractures should be the first aim. Angiography to stop arterial bleeding in the pelvis is often life-saving. The definitive treatment for combined fractures, such as pelvic fractures and femoral shaft fractures, should wait until hemodynamics

    Full Text Available Introduction: Aims of the study to investigate the frequency and the nature ofnail disorders in children significant clinical data is available. Nail disorders although common in children in some parts of our country. This study was carried out to document the clinical and demographic pattern of nail disorders in a dermatology outpatient clinic of a pediatric hospital in Ankara, Turkey. Material and Methods: All consecutive patients a total of 3000 children from age 0-16 were admitted to dermatology outpatient clinic of Ankara Pediatric Hematology and Oncology Education and Research Hospital during January 2011 to December 2011 were studied and retrospectively evaluated for age, gender, drug use, diseases, systemic or genetic disorders and demographic features. Diagnostic evaluation results were noted and patients were categorized for demographic features and diagnosis. Results: These 133 patients (M: F 58:75, %44 vs 56, respectively were under 16 years of age and have 17 different dermatological disorders related with nail symptoms. Fifty three of (39,8% these patient were under 2 years of age, 31 (23.3% were between 3-5 years, 30 (22.5% were between 6-11 years old, 19 of 133 (14%, 2 were between 11-16 years of age. Through all of ages and independent of gender the most etiologies of nail disorders were, onychomadesis, paronychia, onycholysis, onychomycosis and systemic nail presentation of systemic dermatosis. Conclusion: Nail disorders are different in children than in adults. In our study, the first 5 years of age was found in 53% of nail disorders. Nail disorders are uncommon but may be seen as a part of a systemic disease and may be associated with cosmetic and psychologic problem.

    Full Text Available Background: Gel nails are a commonly used cosmetic procedure, though their use by dermatologists has not been evaluated. These can be used to improve the appearance of cosmetically disfigured nails where other treatment options have failed; the condition is self-limiting or irreversible; or to camouflage the dystrophy until healing. Materials and Methods: A prospective, uncontrolled, open-label study on 25 participants presenting with cosmetically disfigured nails was undertaken. Mycologically negative, consenting patients with various nail plate surface abnormalities like trachyonychia (n =8; superficial pitting (n =6; onychorrhexis (n =4; superficial pitting with onychoschizia (n =3; Beau′s lines (n =3 and pterygium (n =1 were included. The patients received gel nail application using Ranara gel nail kit ® . Extra care was taken to avoid any damage to cuticle. Standard pre- and post-treatment photographs were taken to assess improvement. Patient satisfaction score (1-10; Global assessment score of improvement (no improvement to excellent improvement and any side effects reported were recorded. Results: The average age of treated patients was 30.44±11.39 years (range 18-60 years. A total of 69 nails were treated (average of 2.76 per patient. Post-procedure, the average patient satisfaction score was 9.08 ± 0.86 (range 7-10. The Global assessment showed excellent improvement (40% cases; good improvement (56% cases and mild improvement in the single case of pterygium treated. Conclusions: The use of Gel nails in patients with cosmetically disfiguring nail plate surface abnormalities (like trachyonychia, onychoschizia, pitting, etc. was found to produce good to excellent improvement in most of the cases. The patient satisfaction with the procedure was rated as high. This, coupled with absence of side effects, make gel nails a valuable tool in improving cosmesis and satisfaction among patients presenting with nail plate surface abnormalities

    Limited information exists to define standard tibial radiographs. The purpose of this study was to define new landmarks on the proximal tibia for standard anteroposterior and lateral radiographs. In 10 cadaveric knees, fibular head bisection was considered the anteroposterior image, and femoral condyle overlap the lateral image. In another 10 knees, a "twin peaks" anteroposterior view, showing the sharpest profile of the tibial spines, was used. The "flat plateau" lateral image was obtained by aligning the femoral condyles then applying a varus adjustment with overlap of the tibial plateaus. Medial peritendinous approaches were performed, and an entry reamer used to open the medullary canal. A priori analysis showed good to excellent intra-/inter-observer reliability with the new technique (intra-class correlation coefficient ICC 0.61-0.90). The "twin peaks" anteroposterior radiograph was externally rotated 2.7±2.1° compared to the standard radiograph with fibular head bisection. Portal position and incidence of damage to intra-articular structures did not significantly differ between groups (P>.05). The "twin peaks" anteroposterior view and "flat plateau" lateral view can safely be used for nail entry portal creation in the anatomic safe zone. Tibia-based radiographic referencing is useful for intramedullary nailing cases in which knee or proximal tibiofibular joint anatomy is altered.

    Trans-nail permeability is limited due to the innate nature of the nail plate and the recent investigations indicated the potential of iontophoresis in enhancing the transungual drug delivery in normal nails. However, the onychomycotic nails differ from the normal nails with respect to the anatomical and biological features. The current study investigated the effect of iontophoresis (0.5 mA/cm(2) for 1 h) on the transungual delivery of terbinafine in onychomycotic finger and toe nails. The presence of fungi in the onychomycotic nails was diagnosed by potassium hydroxide (KOH) microscopy. Passive and iontophoretic delivery of terbinafine across the infected nail was studied in Franz diffusion cell. Further, the release profile of terbinafine from the drug-loaded nails was investigated by agar diffusion method. KOH microscopy confirmed the presence of fungi in all the nails used. The amount of drug permeated across the nail plate was enhanced significantly during iontophoresis over passive delivery, that is, by 21-fold in case of finger and 37-fold in case of toe nails. Further, the total drug load in the onychomycotic nail was enhanced by ~12-fold (in both finger and toe nails) due to iontophoresis. Release of terbinafine from the iontophoresis-loaded nails into agar plates exhibited two phases, a rapid phase followed by a steady release, which extended >2 months. This study concluded that the drug delivery in onychomycotic nails did not differ significantly when compared with normal nails, although the extent of drug permeation and drug load differs between finger and toe nails.

    Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to existing nails. A novel ratcheting nail was designed and mechanically tested in comparison to a solid nail and a threaded nail using sawbones models (Pacific Research Laboratories, Inc.). Intramedullary nails (IM) were implanted with a load cell (Futek LTH 500) between fusion surfaces. Constructs were then placed into a servo-hydraulic test frame (Model 858 Mini-bionix, MTS Systems) for application of 3 mm and 6 mm dynamic axial displacement (n = 3/group). Load to failure was also measured. Mean percent of initial load after 3-mm and 6-mm displacement was 190.4% and 186.0% for the solid nail, 80.7% and 63.0% for the threaded nail, and 286.4% and 829.0% for the ratcheting nail, respectively. Stress-shielding (as percentage of maximum load per test) after 3-mm and 6-mm displacement averaged 34.8% and 28.7% (solid nail), 40.3% and 40.9% (threaded nail), and 18.5% and 11.5% (ratcheting nail), respectively. In the 6-mm trials, statistically significant increase in initial load and decrease in stress-shielding for the ratcheting vs. solid nail (p = 0.029, p = 0.001) and vs. threaded nail (p = 0.012, p = 0.002) was observed. Load to failure for the ratcheting nail; 599.0 lbs, threaded nail; 508.8 lbs, and solid nail; 688.1 lbs. With significantly increase of compressive load while decreasing stress-shielding at 6-mm of dynamic displacement, the ratcheting mechanism in IM nails may clinically improve rates of fusion.

    Many factors have been noted to alter the growth rate of both finger and toe nails, some with harder evidence than others. Infectious diseases are among the ones reported as slowing the growth rate. However, on previous studies we noticed that patients living with HIV and onychomycosis could be cured without the use of antifungal therapy, only with the immunological improvement provided by the combined antiretroviral therapy, and we wanted to prove that the growth rate is also increased in this group and thus probably contributes to the cure of onychomycosis. This was an observational, descriptive, and prospective study. We marked with a scalpel the nail plate of the first finger of the non-dominant hand and the same foot, and measured the nail growth in the subsequent medical appointments with a magnifying glass and a millimetric scale. Thirteen patients completed the study, and were paired with healthy controls by age and gender. After performing Mann-Whitney U test, our results showed statistical significance among both groups, showing that patients with HIV have faster nail growth rates than those in the HIV negative group. There is little data on HIV nail growth rate to compare our results, but what we see in the clinical practice is that this group of patients shows a faster nail growth rate, as has also been reported for longer eyelashes, and this could be an important factor in the cure rates of onychomycosis. © 2017 The International Society of Dermatology.

    2014-12-01

    The main objective of the current work is to demonstrate the process of passive lateral diffusion in the human nail plate and its effect on the passive transungual permeation of antifungal drug ciclopirox olamine (CPO). A water soluble dye, methyl red sodium salt (MR) was used to visualize the process of lateral diffusion using a novel suspended nail experiment. The decline in concentration of CPO correlates with that of concentration of MR from the proximal to the distal end of the nail in suspended nail study. Three toenails each were trimmed to 5 mm × 5 mm (25 mm(2)), 7 mm × 7 mm (49 mm(2)), and 9 mm × 9 mm (81 mm(2)) to study the extent and effect of lateral diffusion of the CPO on its in vitro transungual permeation. The permeation flux of CPO decreased as the surface area of the toenail increased. There was a positive correlation between the concentrations of CPO and MR in the area of application and in the peripheral area of the toenails of the three surface areas, confirming the findings in the suspended nail experiment. Profound lateral diffusion of CPO was demonstrated and shown to reduce the in vitro passive transungual drug permeation and prolong the lag-time in human toenails. The study data implies that during passive in vitro transungual permeation experiments, the peripheral nail around the area of drug application has to be kept to a minimum, in order to get reliable data which mimics the in vivo situation.

    2004-01-01

    The results of 39 humeral shaft fractures (37 patients) treated with antegrade locked nailing using a Russell-Taylor nail were reviewed. There were 30 acute fractures, 6 fractures malaligned in a hanging cast or brace, and 3 pathological fractures. Patient age ranged from 26 to 80 years (average, 59.7 years) and average follow-up was 25.7 months (range, 6-48 months). Fracture union was achieved in 92.3% of our cases, while shoulder function was excellent or good in 87.2% of cases. Antegrade locked nailing offers a dependable solution for the treatment of humeral shaft fractures, especially in polytrauma patients and cases of segmental or pathological fractures. Far less satisfactory results were obtained in comminuted fractures of the proximal third in the humerus, especially in osteoporotic patients, and we therefore advocate caution with the use of intramedullary nailing in this type of fracture. Certain technical aspects such as avoiding nailing the fracture in distraction, properly countersinking the tip of the nail, and achieving adequate fixation stability have been found to be of paramount importance to reduce the incidence of delayed union/non-union rate and to obtain better functional results from the shoulder joint.

    To describe a system for measurement of the pretraumatic femoral antetorsion angle post-bilateral femoral shaft fracture with the use of new imaging software which allows segmentation and three dimensional (3D) reconstruction of DICOM (digital imaging and communications in medicine) images. This case involved a 20-year-old patient with bilateral femoral shaft fractures. Following initial clinical examination, CT scans of both femurs were performed. Subsequently, the DICOM datasets were uploaded to the new software tool. Following segmentation and 3D reconstruction, pretraumatic femoral antetorsion angles were determined. Femoral antetorsion was described and assessed in two ways by referring to the intersection of the posterior condylar plane and (1) a line drawn between the center of the femoral head and femoral neck, (2) a line drawn between the centers of the femoral head and greater trochanter. Using these definitions, values for femoral antetorsion were found to be, respectively, 20 at the right fracture site and 19 on the left site, and 33 bilaterally. The investigators describe in this current technical report the use of new imaging software which enables the calculation of femoral AV following reduction of virtual fracture fragments which are created from standard DICOM images. We believe that this 3D reconstruction method of measuring the antetorsion angle can be integrated into a regular treatment algorithm and may potentially optimize clinical outcomes. (orig.)

    The objectives of the present study are to clarify the relationship between the physicochemical properties and the nail permeability of drugs through human nail plates. Homologous p-hydroxybenzoic acid esters were used to investigate the relationship between the octanol/water partition coefficient and the permeability coefficient of several drugs. The nail permeability was found to be independent of the lipophilicity of a penetrating drug. However, the nail permeability of several model drugs was found to markedly decrease as their molecular weights increased. The nail permeability of an ionic drug was found to be significantly lower than that of a non-ionic drug, and the nail permeability of these drugs markedly decreased as their molecular weights increased. The permeation of a model drug, 5-fluorouracil (5-FU), through healthy nail plates was also determined and compared with that through nail plates with fungal infections. The drug permeation through a nail plate decreased with an increase in nail plate thickness. Nail plates with fungal infections exhibited approximately the same 5-FU permeation as healthy nail plates. We suggest that the permeability of a drug is mainly influenced by its molecular weight and permeability through nails with fungal infection can be estimated from data on healthy nail permeability.

    Nail lines are a common presenting finding. A thorough inspection of the fingernails and toenails is an integral part of the complete physical examination. An understanding of basic nail anatomy and familiarity with several basic types of nail line enable the clinician to diagnose and treat nail disorders and to recognize underlying systemic diseases, as each type of nail line has a particular differential diagnosis.

    We herein report two cases of atypical femoral fracture (AFF). X-ray examinations at the first visit of these two female patients showed a complete fracture of the femoral diaphysis diagnosed as an atypical femoral fracture (AFF). X-rays of these two cases also showed localized cortical thickening of the femoral diaphysis. Both patients had been taking alendronate for more than 3 years because of postmenopausal osteoporosis. We assumed that both of the fractures were associated with the long-term use of alendronate. However, we retrospectively identified localized cortical thickening of the femoral diaphysis on an X-ray taken before the alendronate therapy in both of these cases. Therefore, we suspected a pathogenesis of AFFs in which preexisting stress or an insufficient fracture unrelated to bisphosphonate (BP) therapy and subsequent suppression of bone turnover due to BP administration led to the occurrence of an AFF. The patient underwent surgery using intramedullary nails in both of these cases, followed by the administration of teriparatide, and they were able to walk without any support at the final follow-up examination.

    Full Text Available Objectives: Yellow nail syndrome (YNS is a rare disease of unknown cause characterized by the triad of yellow nails, respiratory manifestations, and lymphedema. Although several therapies for YNS have been reported, there is no common consensus in the treatment. In this case report, we present a case of 56-year-old woman with YNS, whose nail manifestation was dramatically improved after endoscopic sinus surgery for the treatment of chronic rhinosinusitis. Methods: Endoscopic sinus surgery involving middle meatal antrostomy was performed for the case of YNS with chronic rhinosinusitis and bronchiectasis resistant to antibacterial drugs. Results: A month after the surgery, the patient’s nails eventually showed dramatic improvement. Conclusions: Otorhinolaryngologists should recognize that chronic rhinosinusitis can be a symptom of YNS, and that the aggressive treatment including surgical approach for chronic rhinosinusitis may be a useful in the control of nail manifestation in YNS.

    Full Text Available The aim of the study was to evaluate results of closed intramedullary nailing using Talwarkar square nails in adult forearm fractures. We prospectively evaluated 34 patients with both bone forearm fractures. The average time to union was 12.8 (SD +3.2 weeks with cast support for a mean of 8.2 weeks. Union was achieved in 31 out of 34 patients. Using the Grace and Eversmann rating system, 17 patients were excellent, 10 were good, and 4 had an acceptable result. Three patients had non-unions, 2 for the radius and one for the ulna. There were two cases of superficial infection, one subject had olecranon bursitis, and one case of radio-ulnar synostosis. Complication rates associated with the use of square nails were lower compared to plate osteosynthesis and locked intramedullary nails. To control rotation post- operatively, there is a need for application of an above-elbow cast after nailing.

    Full Text Available The procedure for removing a broken pedicle screw should ideally be technically easy and minimally invasive, as any damage to the pedicle, during removal of the broken screw, may weaken the pedicle, thus compromising on the success of re-instrumentation. We describe the case of a 32-year old man who had undergone surgery for traumatic third lumbar vertebral body fracture three years prior to current admission and had developed the complication of pedicle screw breakage within the vertebral body. The patient underwent re-exploration and removal of the distal screws. Through a paravertebral incision and muscle separation, the screws and rods were exposed and the implants were removed.

    We study the low energy effective theory describing gravity with broken spatial diffeomorphism invariance. In the unitary gauge, the Goldstone bosons associated with broken diffeomorphisms are eaten and the graviton becomes a massive spin-2 particle with 5 well-behaved degrees of freedom. In this gauge, the most general theory is built with the lowest dimension operators invariant under only temporal diffeomorphisms. Imposing the additional shift and SO(3) internal symmetries, we analyze the perturbations on a FRW background. At linear perturbation level, the observables of this theory are characterized by five parameters, including the usual cosmological parameters and one additional coupling constant for the symmetry-breaking scalars. In the de Sitter and Minkowski limit, the three Goldstone bosons are supermassive and can be integrated out, leaving two massive tensor modes as the only propagating degrees of freedom. We discuss several examples relevant to theories of massive gravity.

  19. Broken Ergodicity in Ideal, Homogeneous, Incompressible Turbulence

    2010-01-01

    We discuss the statistical mechanics of numerical models of ideal homogeneous, incompressible turbulence and their relevance for dissipative fluids and magnetofluids. These numerical models are based on Fourier series and the relevant statistical theory predicts that Fourier coefficients of fluid velocity and magnetic fields (if present) are zero-mean random variables. However, numerical simulations clearly show that certain coefficients have a non-zero mean value that can be very large compared to the associated standard deviation. We explain this phenomena in terms of broken ergodicity', which is defined to occur when dynamical behavior does not match ensemble predictions on very long time-scales. We review the theoretical basis of broken ergodicity, apply it to 2-D and 3-D fluid and magnetohydrodynamic simulations of homogeneous turbulence, and show new results from simulations using GPU (graphical processing unit) computers.

    The nail is the largest skin appendage. It grows continuously through life in a non-cyclical manner; its growth is not hormone-dependent. The nail of the middle finger of the dominant hand grows fastest with approximately 0.1 mm/day, whereas the big toe nail grows only 0.03-0.05 mm/d. The nails' size and shape vary characteristically from finger to finger and from toe to toe, for which the size and shape of the bone of the terminal phalanx is responsible. The nail apparatus consists of both epithelial and connective tissue components. The matrix epithelium is responsible for the production of the nail plate whereas the nail bed epithelium mediates firm attachment. The hyponychium is a specialized structure sealing the subungual space and allowing the nail plate to physiologically detach from the nail bed. The proximal nail fold covers most of the matrix. Its free end forms the cuticle which seals the nail pocket or cul-de-sac. The dermis of the matrix and nail bed is specialized with a morphogenetic potency. The proximal and lateral nail folds form a frame on three sides giving the nail stability and allowing it to grow out. The nail protects the distal phalanx, is an extremely versatile tool for defense and dexterity and increases the sensitivity of the tip of the finger. Nail apparatus, finger tip, tendons and ligaments of the distal interphalangeal joint form a functional unit and cannot be seen independently. The nail organ has only a certain number of reaction patterns that differ in many respects from hairy and palmoplantar skin.

    2010-06-01

    Full Text Available Background and Design: Ingrown nail is a common, painful health problem. Various conservative and surgical methods have been defined for treatment of ingrown nails. In this study we aimed to evaluate the efficacy of nail brace treatment which is a cheap conservative treatment, recurrence percentages after nail brace treatment and risk factors for recurrence. Material and Method: Thirty-two female and 19 male patients with the complaint of ingrown nail aged 14-73 with a total of 73 nails are included to the study. Silver nitrate has been applied every 3-7 days to patients with granulation tissue. Nail brace application has been stopped in patients with granulation tissue once the granulation tissue has subsided and complaints have subsided, in patients without granulation tissue as their complaint was over during weekly controls in first month and monthly controls thereafter. Results: Ninety-eight point six percent of patients having ingrown nail (72/73 benefited from brace treatment. In 12 nails out of 71, recurrence has been established, in 59 nails follow-up without recurrence continues. Two nails have not been reached for followup after the first 3 month relief. Assessing patients treated with nail brace for recurrence, no significant difference was detected between recurrent and non-recurrent groups according to stage of ingrown nail, presence of granulation tissue, nail thickness, angle of nail curve, age, gender, presence of hyperhydrosis, duration of treatment and total force applied. Conclusion: Nail brace application has been found effective for pain relief and as treatment in patients with ingrown nails and no statistically significant predictive factor has been found in terms of recurrence after treatment

    The absorption of drugs into the nail unit, following topical application to the nail plate, is highly desirable to treat nail disorders, such as onychomycosis (fungal infections of the nail). Nail permeability is however quite low and limits topical therapy to early/mild disease states. In this paper, the recent research into ungual drug delivery is reviewed. The nail unit and the two most common diseases affecting the nail--onychomycosis and nail psoriasis--are briefly described to set the scene and to give an overview of the nature and scope of the problem. The factors, which affect drug uptake and permeation through the nail plate such as solute molecular size, hydrophilicity/hydrophobicity, charge, and the nature of the vehicle, are then discussed, followed by ways of enhancing drug transport into and through the nail plate. Finally, drug-containing nail lacquers which, like cosmetic varnish, are brushed onto the nail plates to form a film, and from which drug is released and penetrates into the nail, are reviewed.

    2011-01-01

    Nail bracing is a conservative method used for ingrown nails; however, lack of objective measurements limits its use for various nails. Double-string nail braces with extra metal springs were applied to 12 patients with 21 chronic, thick, and overcurved ingrown nails. Force was measured with a force gauge meter. Treatment was stopped once patients stood on their tiptoes and walked in shoes pain free without braces. A force gauge meter was also used on a model nail to show the forces applied by various nail braces and to compare their pulling forces. After 6 to 10 months of treatment, all of the patients were pain free; 600 to 1,000 centi Newtons of force were applied to the nails. As the width of the nail increased, so did the force. Braces exert more force on larger nails, which may shorten treatment durations. By measuring forces, it may be possible to standardize force and duration of treatment according to variables such as nail thickness, nail width, angle of ingrown nail, and duration of symptoms.

    The Arrow FlexTip epidural catheter has reinforced coiled stainless steel wire, which facilitates its insertion and is less likely to puncture the blood vessels. However, as compared with non-reinforced, reinforced epidural catheters are more vulnerable to break. We report a case from Saudi Arabia on a retained fragment of a broken epidural catheter. Measures to prevent this mishap and its management are discussed.

    To investigate the effect of autocontrol micromotion locking nail (AMLN) on experimental fracture healing and its mechanism. 16 goats undergoing both sides of transverse osteotomy of the femoral shafts were fixed intramedullary with AMLN and Gross-Kempf (GK) nail, respectively. The follow-up time was 7, 14, 28 and 56 days. Roentgenographic, biomechanical, histological, scanning electromicroscopic and biochemical analyses were done. (1) The strength of anticompression, antiflexion and antitorsion in the fractural end in the AMLN-fixed group was higher than that of GK nail-fixed group; whereas, the rate of stress shelter in the fractured end decreased significantly (P<0.01). (2) The content of the total collagen, insoluble collagen, calcium and phosphate in the AMLN-fixed group was higher than that in the GK nail-fixed group (P<0.05). (3) Histological observation and quantitative analysis of calluses revealed that AMLN could promote the growth of bridge calluses and periosteum calluses. Hence the fracture healing and remolding process achieved early, which was much better than traditional GK nail fixation. (P<0.05). (4) 7-14 days postoperation, the calluses of AMLN-fixed group was flourish and camellarly arranged and the collagen fibril formed constantly in the absorption lacuna of bone trabecula. 28-56 days postoperation, the collagen fibril was flourish around the absorption lacuna and was parallel to the bone's longitudinal axis. Active bony absorption and formation were seen, so was remolding and rebuilding. Haversian system was intact and the bony structural net was very tenacious because of the deposition of calcium salt. None of the above findings was observed in the GK nail-fixed group. The design of AMLN accords well with the plastic fixation theory. As the geometry ametabolic system constituted by the intramedullary fixation instruments and the proximal and distal end of the fracture is very firm and stable, the disturbance to the physical stress

    2017-01-01

    Psoriasis is a chronic recurrent inflammatory skin disease with prevalence of 1-3%. Nail psoriasis affects 10-90% of patients with plaque psoriasis. The aim of the article is to review the literature for the correlation between nail psoriasis and psoriatic arthritis (PsA) to provide rheumatologists a short review on features of nail psoriasis, methods of their assessment and possible clinical repercussions. The PubMed database was searched using the key words 'nail psoriasis' and 'psoriatic arthritis'. Psoriasis involving the nail matrix shows up as changes such as pitting, Beau lines, leukonychia, red spots in the lunula, or nail plate crumbling. Nail bed psoriasis manifests as onycholysis, oil drops (or salmon patches), dyschromia, splinter hemorrhages, or subungual hyperkeratosis. Nail psoriasis and psoriatic lesions in the gluteal cleft and on the scalp usually accompany PsA, especially in adult men.

    The digital nail complex is occasionally involved by squamous cell carcinoma. The published literature has either been indiscriminating of the site of origin of this tumour within the nail complex or has concentrated attention on the nail bed as the site of pathology. Tumours originating in the lateral nail fold can be clearly differentiated from those of the nail bed itself. This study identifies six cases of squamous cell carcinoma arising in the lateral nail fold. While surgical convention remains to amputate the digital tip for squamous cell carcinoma of any part of the nail complex, the dermatological literature identifies that local surgery can be curative for these tumours, when presenting early and without bone involvement, although offering no discussion of reconstruction. Reconstruction is desirable and methods of achieving this following local excision of lateral nail fold tumours are illustrated in this series.

Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia. The more extensive the involvement, the more severe is the nail destruction. Pustular psoriasis may be seen as yellow spots under the nail or, in case of acrodermatitis continua suppurativa, as an insidious progressive loss of the nail organ. Nail psoriasis has a severe impact on quality of life and may interfere with professional and other activities. Management includes patient counseling, avoidance of stress and strain to the nail apparatus, and different types of treatment. Topical therapy may be tried but is rarely sufficiently efficient. Perilesional injections with corticosteroids and methotrexate are often beneficial but may be painful and cannot be applied to many nails. All systemic treatments clearing widespread skin lesions usually also clear the nail lesions. Recently, biologicals were introduced into nail psoriasis treatment and found to be very effective. However, their use is restricted to severe cases due to high cost and potential systemic adverse effects. Keywords: nail psoriasis, etiology, pathology, quality of life, impact, treatment

  16. Radiation exposure during intramedullary nailing.

    Hak, David J

    2017-06-01

    Surgeons should aim to keep radiation exposure "As Low As Reasonably Achievable (ALARA)" during intramedullary nailing and other minimally invasive surgical procedures. This requires understanding the principles of ionizing radiation and methods for minimizing exposure risk. The main source of radiation exposure to surgical personnel during fluoroscopy is from scattered radiation. Since radiation scatter is mainly directed towards the fluoroscopy source, the best configuration during surgery to reduce radiation dose to the surgeon is to position the fluoroscopic source below the operating room table and the image collector above the table. During cross table imaging, the surgeon should stand on the side with the image collector to minimize their exposure to radiation scatter. To reduce scattered radiation the patient must be placed as close to the image collector and as far away from the x-ray tube as possible. Standing farther away from the patient can exponentially reduce radiation exposure. The hands usually have the greatest dose exposure to radiation during surgical procedures, but they are far less radiosensitive than the eyes or thyroid. To minimize exposure to the hands, a surgeon should use the hands-off technique taking fluoroscopic images only when his or her hands are farthest from the radiographic field. Lead gowns, lead thyroid shields, and lead glasses, further reduces an individual's exposure to radiation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available To estimate postgrouting rock mass strength growth is important for engineering design. In this paper, using self-developed indoor pressure-grouting devices, 19 groups of test cubic blocks were made of the different water cement ratio grouting into the broken rock of three kinds of particle sizes. The shear strength parameters of each group under different conditions were tested. Then this paper presents a quantitative calculation method for predicting the strength growth of grouted broken rock. Relational equations were developed to investigate the relationship between the growth rates of uniaxial compressive strength (UCS, absolute value of uniaxial tensile strength (AUTS, internal friction angle, and cohesion for post- to pregrouting broken rock based on Mohr-Coulomb strength criterion. From previous test data, the empirical equation between the growth rate of UCS and the ratio of the initial rock mass UCS to the grout concretion UCS has been determined. The equations of the growth rates of the internal friction coefficient and UCS for grouting broken rock with rock mass rating (RMR and its increment have been established. The calculated results are consistent with the experimental results. These observations are important for engineered design of grouting reinforcement for broken rock mass.

    Bisphosphonates are widely used for the prevention of osteoporosis-associated fractures. Femoral fractures associated with bisphosphonate use are increasingly being reported in the literature. Orthopedic surgeons should be aware of this potential association and related implications for patient treatment. Bisphosphonate-associated fractures are characteristically simple, transverse with beaking, and subtrochanteric. Diagnosis is based on a careful history, physical examination, and focused imaging. In the setting of either a complete or partial fracture, it is recommended that bisphosphonate therapy be halted and calcium and vitamin D brought into the therapeutic range. Orthopedic management of the completed fracture preferably uses a locked intramedullary nail. The recommendations for incomplete fractures are unresolved. [Orthopedics. 2016; 39(6):e1036-e1040.].

    Full Text Available History of present illness: A 74-year-old male presented to the emergency department with left hip pain after falling off his bicycle. Pain is 3/10 in severity and exacerbated by movement. Patient denied head trauma. Exam showed left hip tenderness, 3/5 left lower extremity strength secondary to pain, and 5/5 right lower extremity strength. Sensation and pulses were intact in bilateral lower extremities. Left hip X-ray and pelvic CT revealed comminuted, impacted transcervical and subcapital fracture of the left femoral neck. Significant findings: In the anteroposterior view bilateral hip x-ray, there is an evident loss of Shenton’s line on the left (red line when compared to the normal right (white line, indicative of a fracture in the left femoral neck. This correlates with findings seen on pelvic CT, which reveals both a subcapital fracture (blue arrow and transcervical fracture (yellow arrow. The neck of the femur is displaced superiorly relative to the head of the femur while the head of the femur remains in its anatomical position within the acetabulum. Discussion: Femoral neck fractures are one of the most common types of hip fractures, accounting for 49.4% of all hip fractures.1 Diagnosing a femoral neck fracture can be made with plain x-ray, CT, or MRI. Plain film radiographs have been found to be at least 90% sensitive for hip fractures CT’s have been found to be 87%-100% sensitive and 100% specific for occult hip fractures in which plain radiographs were read as negative, but the patient still complained of hip pain Although MRI is currently the gold standard for detecting occult hip fractures (sensitivity and specificity = 100%, given MRI’s limited accessibility in the ED as well as the high sensitivity and specificity of CT scans for occult hip fractures, it is generally recommended to obtain CT scans for patients with suspected occult hip fractures as a first-line investigation

    We describe a case of a severely comminuted type iiia open tibial fracture, with distal loss of bone stock (7 cm), total involvement of the tibial joint surface, and severe instability of the fibular-talar joint. The treatment performed consisted of thorough cleansing, placing a retrograde reamed calcaneal-talar-tibial nail with proximal and distal blockage, as well as a fibular-talar Kirschner nail. Primary closure of the skin was achieved. After 3 weeks, an autologous iliac crest bone graft was performed to fill the bone defect, and the endomedullary nail, which had protruded distally was reimpacted and dynamized distally. The bone defect was eventually consolidated after 16 weeks. Currently, the patient can walk without pain the tibial-astragal arthrodesis is consolidated. Copyright © 2013 SECOT.

    We demonstrate in open microcavities with broken chiral symmetry, quasi-degenerate pairs of co-propagating modes in a non-rotating cavity evolve to counter-propagating modes with rotation. The emission patterns change dramatically by rotation, due to distinct output directions of CW and CCW waves. By tuning the degree of spatial chirality, we maximize the sensitivity of microcavity emission to rotation. The rotation-induced change of emission is orders of magnitude larger than the Sagnac effect, pointing to a promising direction for ultrasmall optical gyroscopes.

    Femoral shaft fractures are common presentation in our trauma units. It is obvious that all these fractures cannot be treated conservatively due to the pressure on trauma beds and thus a suitable method of internal fixation that is feasible in the environment has had to be adopted. This study is a report of our experience with plate fixation of femoral shaft fracture in our environment. A retrospective hospital based study. All patients with femoral shaft fractures stabilized with plates and screws between 1997 and 2004 at the University College Hospital were reviewed. The case notes were retrieved and data extracted from them; all case notes entry gave sufficient information. The fracture pattern showed 56 cases (35.4%) of Type 32-A, 45 cases (28.5%) of Type 32-B and 57 cases (36.1%) of Type 32-C using AO classification. The outcome of treatment was excellent to good in 125 fractures (77.2%). The average time of healing was 20 weeks (range 16-48). Fracture related complications occurred in nine fractures (5.7%) which included deep infection in four fractures (2.5%) and implant failure in five fractures (3.2%). Femoral shaft plating gives good result if the principles of fixation is carefully followed and in developing countries where initial cost of procurement of equipments for closed nailing may not be forth coming, it thus provide a safe efficient and low cost method of fixation of femoral shaft fracture.

    Nails are underutilized as diagnostic tools, despite being involved in many dermatologic conditions. This paper explores new concepts in the treatment of median nail dystrophy (MND), onychomycosis, and the nail pathology of hand, foot, and mouth disease (HFMD). A Pubmed database literature search was conducted for MND treatment, onychomycosis treatment, and HFMD nail pathology. Only papers published after January 2008 were reviewed. The results showed that 0.1% tacrolimus ointment can be an effective treatment for MND. Early studies on laser therapy indicate that it is a safe and efficacious treatment option for onychomycosis, compared to conventional oral antifungal agents. Vicks VapoRub (The Proctor & Gamble Company, Cincinnati, OH) is effective against onychomycosis and is a reasonable option in patients who choose to forgo conventional treatments. Lastly, there is evidence to support a correlation between HFMD and onychomadesis.

  15. 1st meeting on topical drug delivery to the nail.

    2007-07-01

    The first ever symposium dedicated solely to drug delivery to the nail following topical application was held on the 2nd April 2007, in London, UK, organised by Dr Clive Roper (Charles River Laboratories, Scotland) and Dr Sudaxshina Murdan (School of Pharmacy, University of London, UK), under the auspices of Skin Forum. The 1-day meeting was attended by approximately 35 delegates from industry, academia and hospitals, and provided a much-needed forum for the presentation and discussion of research and problems in this emerging field. Topical drug delivery is especially suitable for onychomycosis (fungal infections of the nail plate and/or nail bed) and nail psoriasis, which affect 2 - 13 and 1 - 3% of the general population, respectively, and make up the bulk of nail disorders. Topical therapy would avoid the adverse events and drug interactions of systemic antifungal agents and the pain of injection when antipsoriatic agents are injected into affected nail folds. However, successful topical therapy is extremely challenging due to the very low permeability of the nail plate. Five speakers spoke about various aspects of topical drug delivery to the nail, including review of the nail plate structure, function, diseases, their existing therapies (systemic and topical), limitations and global sales. The need for effective topical drug delivery to the nail to overcome the problems associated with present treatment, and the fact that there are few topical formulations available for the treatment of nail fungal infections and psoriasis, and the even fewer effective formulations, was highlighted.

    Full Text Available Nail psoriasis affects a large number of patients with psoriasis and has a major psychosocial impact. Furthermore, it may be regarded as a predictor of more severe forms of psoriasis and early sign of psoriatic arthritis. The clinical presentations vary depending on the structure affected (nail matrix or nail bed, the nail lesions may range from minor to severe, but they are not specific. Treatment is a challenge, in most cases the lesions being resistant to therapy. We present a rare case of psoriasis with nail onset in a 59-year-old woman. The nail involvement confined to the fingernails was severe, with significant impairment of the patient’s quality of life. Conventional therapies failed to improve the nail lesions, but a marked improvement was achieved under etanercept therapy

    Full Text Available Abstract Introduction We present a rare case of two concomitant morbidities treated in one operation. To our knowledge, this is the first report of its kind in the literature. Case presentation A 57-year-old Greek woman was admitted to the emergency department having sustained a spiral mid-shaft femoral fracture. She also suffered from an ipsilateral hip congenital dysplasia with ankylosed hip joint due to severe arthritis. She was treated with a total hip arthroplasty using a long stem performing as an intramedullary nail. Conclusion We undertook a complex operative treatment of both co-morbidities in a one stage procedure with a satisfactory clinical result.

    2011-01-01

    Full Text Available Slipped capital femoral epiphysis is a common injury suffered by adolescents worldwide. Treatment of most slips can be accomplished by percutaneous screw fixation, as this is an accepted and proven method associated with minimal morbidity. Complications, although limited, can be problematic for both the patient and treating physician. These include avascular necrosis, chondrolysis, infection, and fracture. We report a case of an individual who sustained a subtrochanteric femure fracture three weeks after in situ pinning of his left hip treated with a reconstruction intramedullary nail. This option allowed both the subtrochanteric fracture and SCFE to be treated concomitantly with minimized morbidity.

    Ingrown toe nail is a common foot problem; however, there are limited data concerning the treatment options for diabetic patients. Because of the special attention given to avoidance of infection and ulceration of the foot in diabetics, we applied a new, simple nail device as a treatment option without any systemic treatment or surgical intervention. We applied braces to 21 diabetic patients with ingrown toe nails. All had severe pain, erythema, and edema without suppuration or granulation tissue formation. Braces were applied until all the symptoms are cleared. We followed the patients for 2 years for the recurrence of symptoms and signs. All patients had immediate relief of symptoms once the brace was applied. After the dislocation of braces, 15 of 21 patients did not have any recurrences for 2 years. Six patients had recurrence of pain and ingrown nail and were willing to use the brace once more instead of having any operations. Nail brace application is a safe, simple, and inexpensive treatment option for diabetic patients with ingrown toe nails. Although there may be recurrences, patients are willing to use it for a second time as it is simple and pain free.

    Lichen planus (LP) is a common skin disorder of unknown aetiology that affects the skin, mucous membranes and nails. Although metal allergies have been implicated in the development of oral LP (OLP), the contribution of these allergies to nail LP (NLP) has yet to be studied in detail. To elucidate the link between metal allergy and NLP. We retrospectively analysed 115 LP patients with respect to the contribution of metals to either NLP or OLP. We also attempted to detect the specific metals involved in these nail lesions. Of the 79 patients that received a metal patch test (PT), 24 (30%) were positive for at least one of the metal compounds tested. Notably, the prevalence of positive reactions to metals in the NLP patients was significantly higher as compared with the OLP patients (59% vs. 27%, P braces were detected in the involved nail tissues. This study suggests that metal allergies are more closely associated with NLP vs. OLP, and that deposited metals in the nail apparatus contribute to the development of lichenoid tissue reactions in the nail bed and matrix. © 2012 The Authors.

    Pincer nail is a nail deformity characterized by transverse overcurvature of the nail plate. Pincer nail can affect a patient's quality of life due to its chronic, recurrent course; however, there have been no clinical studies on the pincer nail condition in Korean patients. The purpose of this study was to characterize the clinical findings and treatment of pincer nail. In addition, possible etiological factors were considered, and treatment efficacy was evaluated. The medical records and clinical photographs of 35 patients (12 males, 23 females) who were diagnosed with pincer nail between August 1, 2005 and July 31, 2009 were studied. Patient age ranged from 10 to 77 (52.09±17.26) years, and there was a predominance of female (23 out of 35 patients, F:M=2:1). The mean duration of the disorder was 7.45 years (range 0.25~40); 85% had pincer nail for at least 1 year. In addition, 40% had a history of previous treatment and recurrence. There were 82.8% patients with the common type of pincer nails. The most commonly involved nails were both great toenails. Among 35 patients, nail grinding was started in 30 patients, and 25 patients showed clinical improvement with nail grinding. The width index increased and the height index decreased after treatment. The mean follow up period was 8.42 months (range 1~27), and 7 patients showed recurrence after 8.8 months (range 2~20). Among 35 patients, 5 patients were treated with nail extraction with matricectomy, and the symptoms resolved immediately. The mean follow up period was 7.6 months (range 0~19), and recurrence was not observed. Onychomycosis was also present in 37.1% of patients, and itraconazole pulse therapy for 3 months was added. The results of this study demonstrate the clinical features of pincer nail in Korean patients. The findings show that the common type of pincer nail was most common, and nail grinding as a conservative treatment greatly improved pincer nails despite a risk of recurrence. When onychomycosis

    Intramedullary nailing is the treatment of choice for fractures of the tibial shaft, which might necessitate the nail removal due to complications in the long-term. Although considered as a low-risk procedure, intramedullary nail removal is also associated with certain complications. Here, we compared the most commonly used stainless steel and titanium nails with respect to the complications during removal and clinical outcome for intramedullary nailing of diaphyseal fractures of the tibia. Sixty-two patients (26 females, 36 males) were included in this retrospective study. Of the removed nails, 24 were of stainless steel and 38 of titanium. Preoperative and intraoperative parameters, such as implant discomfort, anterior knee pain, operating time and amount of bleeding, and postoperative outcomes were evaluated for each patient. Titanium nail group had more, but not statistically significant, intraoperative complications than stainless steel group during the removal of nails (p = .4498). Operating time and amount of intraoperative bleeding were significantly higher in titanium group than stainless steel group (p = .0306 and p stainless steel nails, whereas there was no difference in terms of postoperative SF-36 and KSS scores. In conclusion, although greater bone contact with titanium increases implant stability, nail removal is more difficult, resulting in more longer surgical operation and more intraoperative bleeding. Therefore, we do not recommend titanium nail removal in asymptomatic patients.

    2013-03-01

    Focal femoral inlay resurfacing has been developed for the treatment of full-thickness chondral defects of the knee. This technique involves implanting a defect-sized metallic or ceramic cap that is anchored to the subchondral bone through a screw or pin. The use of these experimental caps has been advocated in middle-aged patients who have failed non-operative methods or biological repair techniques and are deemed unsuitable for conventional arthroplasty because of their age. This paper outlines the implant design, surgical technique and biomechanical principles underlying their use. Outcomes following implantation in both animal and human studies are also reviewed.

    Mittal, Ravi; Banerjee, Sumit

    2012-01-01

    Purpose The purpose of this study was to review the principles involved in the management of proximal femoral fractures as reported in the literature. Methods: A medical literature search in the MEDLINE (PubMed) and Cochrane database was undertaken to review strategies and principles in proximal femoral fracture treatment. Randomized control trials and meta analysis were given preference while case reports/small series were rejected. Results and conclusions: Early anatomical reduction and surgical fixation remains the best option to reduce the risk of complications like non-union and avascular necrosis in treating fracture neck femurs. Cancellous screws continue to be the preferred treatment for fixation of neck femur fractures in younger population until the benefit of using sliding hip screws is validated by large multicentric studies. In the geriatric age group, early prosthetic replacement brings down the mortality and morbidity associated with neck femur fractures. Sliding hip screw (DHS) is the best available option for stable inter trochanteric fractures. The use of intramedullary nails e.g. PFN is beneficial in treating inter trochanteric fractures with comminution and loss of lateral buttress. Intramedullary implants have been proven to have increased success rates in subtrochanteric fractures and should be preferred over extramedullary plate fixation systems. PMID:25983451

    Mono(meth)acrylates (monoacrylates and monomethacrylates) are moderate to strong sensitizers. They are used in the production of a great variety of polymers, including nail cosmetics. A patient who became occupationally sensitized to photobonded sculptured nails is reported. Detailed patch testing and analyses of the patient's nail cosmetics containing mono(meth)acrylates clarified the cause of her hand and face dermatitis. The current knowledge on mono(meth)acrylates in nail cosmetics is also reviewed. Patch testings with conventional methods, including patch testing with the patient's own substances, were performed. The patient's nail cosmetics suspected of containing mono(meth)acrylates were analyzed with gas chromatography/mass spectrometry analysis. In the (meth)acrylate series, 15 of the 31 (meth)acrylate compounds tested gave an allergic reaction: 2 acrylates, 5 methacrylates, 3 dimethacrylates, and 5 diacrylates. Epoxy diacrylates, cyanoacrylate, triacrylates, and methacrylic acid were negative. Three of seven of her own nail cosmetic preparations contained mono(meth)acrylates as revealed by the gas chromatography/mass spectrometry analysis, and these also gave allergic patch test reactions, namely, the nail liquid, nail hardener, and UV-cured nail gel. The patient probably had been sensitized to the following (meth)acrylate compounds from her nail cosmetics: tripropylene glycol diacrylate and methyl acrylate from her photobonded nail gel; ethyl methacrylate, triethylene glycol dimethacrylate, and methyl methacrylate from her nail liquid; and butyl methacrylate from her nail hardener. She was probably also sensitized to the rare sensitizer aliphatic urethane diacrylate, but the source was not verified. Because nail cosmetics containing mono(meth)acrylates are strong sensitizers, both the workers and the customers should be aware of their sensitizing capacity; they should use no-touch techniques regarding the skin before the mono(meth)acrylates are

    Regulation of adult stem cells (SCs) is fundamental for organ maintenance and tissue regeneration. On the body surface, different ectodermal organs exhibit distinctive modes of regeneration and the dynamics of their SC homeostasis remain to be unraveled. A slow cycling characteristic has been used to identify SCs in hair follicles and sweat glands; however, whether a quiescent population exists in continuously growing nails remains unknown. Using an in vivo label retaining cells (LRCs) system, we detected an unreported population of quiescent cells within the basal layer of the nail proximal fold, organized in a ring-like configuration around the nail root. These nail LRCs express the hair stem cell marker, keratin 15 (K15), and lineage tracing show that these K15-derived cells can contribute to both the nail structure and peri-nail epidermis, and more toward the latter. Thus, this stem cell population is bifunctional. Upon nail plucking injury, the homeostasis is tilted with these SCs dominantly delivering progeny to the nail matrix and differentiated nail plate, demonstrating their plasticity to adapt to wounding stimuli. Moreover, in vivo engraftment experiments established that transplanted nail LRCs can actively participate in functional nail regeneration. Transcriptional profiling of isolated nail LRCs revealed bone morphogenetic protein signaling favors nail differentiation over epidermal fate. Taken together, we have found a previously unidentified ring-configured population of bifunctional SCs, located at the interface between the nail appendage organ and adjacent epidermis, which physiologically display coordinated homeostatic dynamics but are capable of rediverting stem cell flow in response to injury.

    2014-01-01

    Full Text Available The 40 years old Standard Model, the theory of particle physics, seems to describe all experimental data very well. The theory is based on symmetries, some of them are broken, mostly by the weak interaction. All of its elementary particles were identified and studied apart from the Higgs boson until 2012, when the two main experiments of the Large Hadron Collider at CERN, CMS and ATLAS observed a new particle with properties close to those predicted for the Higgs boson. The discovery of the Higgs boson proves the validity of the Brout-Englert-Higgs mechanism of spontaneous symmetry breaking and François Englert and Peter Higgs received the 2013 Nobel Prize in Physics. There are several questions yet concerning the possible theoretical significance of the mass of the new particle.

  13. Modified broken rice starch as fat substitute in sausages

    Valéria Maria Limberger

    2011-09-01

    Full Text Available The demand for low-fat beef products has led the food industry to use fat substitutes such as modified starch. About 14% of broken rice is generated during processing. Nevertheless, this by-product contains high levels of starch; being therefore, great raw material for fat substitution. This study evaluated the applicability of chemically and physically modified broken rice starch as fat substitute in sausages. Extruded and phosphorylated broken rice was used in low-fat sausage formulation. All low-fat sausages presented about 55% reduction in the fat content and around 28% reduction in the total caloric value. Fat replacement with phosphorylated and extruded broken rice starch increased the texture acceptability of low-fat sausages, when compared to low-fat sausages with no modified broken rice. Results suggest that modified broken rice can be used as fat substitute in sausage formulations, yielding lower caloric value products with acceptable sensory characteristics.

    Antegrade intramedullary nailing has become the gold standard to treat two-, three-, and four-part cephalo-tuberosity fractures. We report a retrospective study of 6 patients who have undergone centro-medullary nailing since January 2012. Mean follow-up was 12 months; the average age was 57 years. Clinical evaluation was based on gross and weighted Constant and Murley score, based on the age and sex, compared to the "normal" body surface area. Radiological assessment allowed us to evaluate bone healing, the occurrence of osteonecrosis of femoral head or of post-traumatic arthrosis. Radiological examination focused even on the state of the tuberosities and on the existence or not of osteolysis of the greater tubercle of the humerus. It was also used to identify the criteria for good reduction, namely cephalic cap angle and diaphyseal axis (αF) in face views. All patients underwent the same surgical procedure. Constant and Murley score for all patients was 64.13 points. Weighted score based on age and sex was 73%. Joint mobility was estimated at an average of 116° for all patients in anterior elevation, 99.9° in lateral elevation, and 42° in external rotation. Average αF angle was 42°. All patients met criteria for good reduction, namely αF. Centro-medullary nailing allows simple and cost-effective bone synthesis with very promising functional results.

    To describe early clinical experience with a newly designed interlocking nail system (Targon(®) Vet) in diaphyseal fractures in cats and small dogs. Retrospective case series. Client-owned cats (n=49) and dogs (n=8). Fifty-seven consecutive cases (49 cats, 8 dogs) with 60 long bone fractures were included in the study. Follow-up radiographs were scheduled at 4 and 8 weeks and again 6 months postoperatively. The end point for each case was determined radiographically by a healed fracture. Complications were defined as minor or major. Clinical outcome was subjectively assessed by a full orthopedic examination and follow-up radiographs. Descriptive data are reported. Median age of cats was 18 months (range, 3-220 months) and of dogs was 28 months (range, 7-115 months). Median body weight was 3.7 kg (range, 1.67-8.41 kg) for cats and 8.15 kg (range, 2.68-13.6 kg) for dogs. Median radiographic follow-up was 16 weeks. All fractures with follow-up radiographs available (n=46) were healed with no infections reported. A total of 12 postoperative complications occurred: 3 minor (slippage of the locking screws) and 9 major (5 femoral-irritation of the sciatic nerve, stress protection, fracture because of a missed fissure, femoral neck fracture, intra-operative revision with a rod and plate; 4 tibial-3 with protrusion of the distal locking screw through the skin and 1 with in-growth of the intramedullary nail). Implantation of the Targon(®) Vet System was feasible in all cases. It provides an alternative system for diaphyseal fracture repair in cats and small dogs. © Copyright 2016 by The American College of Veterinary Surgeons.

    To evaluate the outcome of knee fixation without bone fusion using an intramedullary modular nail and interposed cement. Retrospective study of 29 infected total knee arthroplasties with prospective data collection and a mean follow-up of 4.2 years (3-5). Complications included 2 recurrent infections, 1 peri-implant fracture, and 1 cortical erosion due to the tip of the femoral component. All of these were revised with successful results. The mean limb length discrepancy was 0.8 cm, with 24<1cm. Twenty-five patients reported no pain. The mean WOMAC-pain was 86.9, WOMAC-function 56.4, SF12-physical 45.1, and SF12-mental 53.7. Four patients needed a walking frame, and only two were dependent for daily activities. The Endo-Model Link nail is an effective method for knee fixation that restores the anatomical alignment of the limb with adequate leg length. Copyright © 2014 SECOT. Published by Elsevier Espana.

    Sarcoidosis is a granulomatous disease which can affect multiple organ systems. Clinical and radiologic manifestations depend on the organ system involved and the chronicity of disease. Nail involvement in sarcoidosis is rare, but is clinically relevant as it indicates chronic systemic disease. Nail abnormalities can be identified radiographically, and when seen in patients with known or suspected sarcoidosis, should prompt careful evaluation of the underlying bone for osseous involvement. We describe a case of sarcoidosis with radiographic findings in the nails and distal phalangeal tufts, which were indicative of nail and osseous sarcoid involvement and strongly supported the presence of chronic systemic disease. Although the nail findings resolved clinically and on radiographs after treatment, the osseous findings showed only minimal improvement. To our knowledge, the radiographic findings of nail sarcoidosis have not been previously addressed in the literature. (orig.)

  20. Bilateral atypical femoral fractures in a patient prescribed denosumab - a case report.

    Thompson, Robin N; Armstrong, Ciara L; Heyburn, Gary

    2014-04-01

    Atypical fractures of the diaphyseal femoral shaft have been reported in the literature at an increasing rate over the past few years. They have been observed mostly in patients who have been on prolonged courses of bisphosphonates, with no reported cases of atypical femoral fractures in those treated with other anti-resorptive medications. A 59 year old woman sustained an atypical fracture of her right femur in March 2013. She had a past medical history of rheumatoid arthritis and osteoporosis. She had been on alendronate but it was discontinued after five years in 1999. She received denosumab by subcutaneous injection in December 2012. At follow up, she complained of pain in her left femur and a radiograph revealed atypical appearances. She was admitted in June 2013 for prophylactic nailing of the left femur. To our knowledge, this is the first reported case of bilateral atypical femoral changes in a patient prescribed denosumab. Given that denosumab has been on the market for a short time period, we expect that the number of these cases will increase with time. We emphasise previous guidance that patients who present with new onset hip or thigh pain should be screened for atypical femoral fractures. Copyright © 2013 Elsevier Inc. All rights reserved.

    Summary: Compression techniques seem to be the primary factor in determining the success of both plating and nailing techniques for the management of acute fractures and for delayed and nonunion management of these fractures. An intramedullary nail that can provide continual compression (like a plate) and mechanical manipulation of the callous throughout the course of treatment is an ideal device that provides all the advantages of plating and nailing and avoids the noted limitations of both....

    The purpose of this study is to report our experience of fractures in children riding Hoverboards. We undertook a prospective review of all children attending our hospital who sustained fractures whilst riding a Hoverboard. Data such as patient demographics, type of fracture sustained, treatment received, complications and outcome were collected. Twelve children, 5 males and 7 females with ages ranging from 5.5 to 15.3 years were included in this study. All patients sustained upper limb fractures and the distal radius was the commonest fracture site (30%). Surgery was required in 6 (50%) out of the 12 patients because the respective fractures were displaced. No patient had any ongoing complaints or disability at the last clinic review.   Conclusion : Children riding Hoverboards are predisposed to upper limb fractures and parents who purchase Hoverboards should be warned about this.

  11. Gauze strip tourniquet for nail surgery

    Directory of Open Access Journals (Sweden)

    Chander Grover

    2014-01-01

    Full Text Available All nail surgical procedures require the use of a tourniquet. The nail bed, being a very vascular structure, needs to be exsanguinated at the start and then a tourniquet needs to be tied at the base. A number of tourniquets have been described, including a Foley′s catheter, a Penrose drain, a rubber strip or a rubber band. The present article explains the use of the easily available, improvised, gauze strip tourniquet. This does not require much special preparation, is easily autoclavable, perfect for single use and can achieve exsanguination as well as tightening as a single step. This technique does not require much learning and is easily reproducible in almost all surgical setups.

    The most important complication of lumber disc hernia operations is Failed Back Surgery Syndrome (FBSS), which goes with fibrotic adhesions at the surgical site. The primary treatment applied to the cases that develop FBSS is the placement of Racz catheter under floroscopy and application of epidural neuroplasty which is a three-day procedure. However, this intervention, from which patients benefit a great deal, has some important complications during and after the application. One of these complications is that some pieces of Racz catheter may be broken out and retain at some levels of epidural space and subcutaneous tissue during placement and removal. General approach is to remove the retaining piece surgically. However, there is a less common view that, instead of removing the retaining piece, the patient should be followed up strictly and regularly in terms of neurologic complications. In our case, we decided to perform epidural neuroplasty to the patient diagnosed as FBSS. However, during the placement of the catheter, it was trapped in the left side of L5-S1 foramen by accident due to dense fibrotic tissues, and the subcutaneus part retained in the epidural space. Monthly follow-ups for 12 month were proposed to the patient, while surgery was not recommended. At the end of this period, no sign of infection was observed and neurologic and radiologic findings of the patient did not worsen. It is also interesting that a remarkable recovery was observed in the patient's clinical situation.

    2015-01-01

    Planck's Law, an equation used by physicists to determine the radiation leaking from any object in the universe, was described by Albert Einstein as "the basis of all twentieth-century physics." Max Planck is credited with being the father of quantum theory, and his work laid the foundation for our modern understanding of matter and energetic processes. But Planck's story is not well known, especially in the United States. A German physicist working during the first half of the twentieth century, his library, personal journals, notebooks, and letters were all destroyed with his home in World War II. What remains, other than his contributions to science, are handwritten letters in German shorthand, and tributes from other scientists of the time, including his close friend Albert Einstein. In Planck: Driven by Vision, Broken by War, Brandon R. Brown interweaves the voices and writings of Planck, his family, and his contemporaries-with many passages appearing in English for the first time-to create a portrait of...

    Simborg, Donald W; Detmer, Don Eugene; Berner, Eta S

    2013-06-01

    In 2005, the authors published a paper, 'Will the wave finally break? A brief view of the adoption of electronic medical records in the United States', which predicted that rapid adoption of electronic health records (EHR) would occur in the next 5 years given appropriate incentives. The wave has finally broken with the stimulus of the health information technology for economic and clinical health legislation in 2009, and there have been both positive and negative developments in the ensuing years. The positive developments, among others described, are increased adoption of EHR, the emergence of a national network infrastructure and the recognition of clinical informatics as a medical specialty. Problems that still exist include, among others described, continued user interface problems, distrust of EHR-generated notes and an increased potential for fraud and abuse. It is anticipated that in the next 5 years there will be near universal EHR adoption, greater emphasis on standards and interoperability, greater involvement of Congress in health information technology (IT), breakthroughs in user interfaces, compelling online medical and IT education, both increased use of data analytics for personalized healthcare and a realization of the difficulties of this approach, a blurring of the distinction between EHR and telemedicine, a resurgence of computer-assisted diagnosis and the emergence of a 'continuously learning' healthcare system.

  15. Yellow nail syndrome: does protein leakage play a role?

    D'Alessandro, A; Muzi, G; Monaco, A; Filiberto, S; Barboni, A; Abbritti, G

    2001-01-01

    Yellow nail syndrome is characterized by primary lymphoedema, recurrent pleural effusion and yellow discoloration of the nails. Although mechanical lymphatic obstruction is assumed to be the underlying pathology, it cannot explain the common finding of high albumin concentration in the pleural space. This paper describes a case of yellow nail syndrome presenting with the classical triad of lymphoedema, recurrent pleural effusion and yellow discoloration of the nails, associated with persistent hypoalbuminaemia and increased enteric loss of albumin. Based on the findings in this case and those in the literature, it is speculated that increased microvascular permeability may contribute to the pathogenesis of this syndrome.

  16. The nail dermis: from microanatomy to constitutive modelling.

    Science.gov (United States)

    Perrin, Christophe

    2015-05-01

    The nail mesenchyme, as ligamentous connective tissue, is classically described as a single compartment. Some authors have even suggested the concept of the nail as a musculoskeletal appendage. Recent studies conducted on supernumerary digits surgically removed for polydactyly or on the developing nail organ have introduced into the literature a new concept: the onychodermis and its onychofibroblasts that are CD10-positive/CD34-negative. The aim of this study was to explore the nail mesenchyme more comprehensively. A series of 10 normal adult nail units were examined with a combination of morphological and immunohistochemical analysis. This study demonstrates that the nail mesenchyme has two distinct compartments, with a complex microanatomy of matrical dermis and its hypoderm. The matrical dermis is a relatively independent substructure, and comprises two parts: a thin papillary dermis, and a relatively thick reticular dermis. The matrical hypoderm corresponds to a cushion-like layer of adipose tissue, which distally intermingles with an area of loose connective tissue. The nail bed dermis comprises a single, relatively homogeneous compartment. The matrical nail mesenchyme is a modified dermis. The concept of onychodermis is not applicable in the normal adult nail. Underrecognized non-pathological structures may pose diagnostic problems. The chameleon matrical hypoderm is one such structure. © 2014 John Wiley & Sons Ltd.

    The authors herein describe several nail conditions, which the general pediatrician is likely to encounter in the course of routine practice. Because pediatric nail disorders represent a limited component of a general pediatric practice, it can be challenging for practitioners to establish expertise in the diagnosis and treatment of these conditions and to recognize when reassurance is appropriate or when referral to a specialist is necessary. This article summarizes the anatomy of the normal nail unit, as well as the evaluation and management of onychomycosis, melanonychia, trachyonychia, onychomadesis, and nail pitting.

    1983-12-01

    Tc-/sub 99m/ diphosphonate bone scans were performed on 11 children with slipped capital femoral epiphysis. On pinhole hip images, seven hips in seven patients had increased radionuclide uptake in the physis and adjacent proximal femoral metaphysis where the slip had occurred. Three hips in three patients had decreased radionuclide uptake in the femoral head on the side of the slipped epiphysis, indicating compromise of the femoral head blood supply. Three or more months following internal fixation, three children had scintigraphy that showed loss of the usual focal uptake in the physis and adjacent proximal femoral metaphysis. Bone scintigraphy in pediatric patients with slipped capital femoral epiphysis is valuable in defining the metabolic status of the femoral head. Absence of radiopharmaceutical uptake in the affected femoral head indicates that the femoral head is at risk for development of radiographic changes associated with aseptic necrosis.

    2017-06-01

    Ingrown nails are a common problem, seen mostly in young adults. Also known as onychcrypotisis, this condition typically affects the great toenail. Four stages have been defined according to the severity and duration of the condition, and treatment varies from conservative to surgical techniques depending on the stage. We present our experience with this condition, describing the characteristics of our population and surgical treatment, in particular the super U technique. This was a retrospective, descriptive study of patients with ingrown great toenail treated surgically using the super U technique. We also describe postoperative management. Ten patients with a mean age of 35.7 years underwent operation, 9 for unilateral ingrown great toenail and 1 for bilateral disease. Stage II ingrown nail was the most common. Half of the patients had been treated previously using other surgical techniques. The mean time to healing was 6 weeks. The only postoperative complication was infection in 1 patient. Mild to moderate postoperative pain persisted for a week. The majority of patients were satisfied with the cosmetic result. We believe the super U technique is very useful in stage II ingrown nail and in disease that has recurred after previous surgery, and is the treatment of choice in stage III or IV disease in which excessive hypertrophic tissue is found.

    2013-01-01

    To assess the relationship between nail configuration and mechanical force, the nail morphology and pinch strengths of the paralyzed and non-paralyzed sides of patients with hemiplegia were measured. Study 1: Analysis of nail configuration. Both thumb nails of 100 subjects with hemiplegia and 100 healthy volunteers (400 thumb nails) were enrolled. The left and right thumb nails were compared in terms of configuration, namely the curve index (defined as nail height/width). Study 2: Measurement of pinch strength. In 10 subjects with hemiplegia and 10 healthy volunteers, the pinch strengths of both sides were compared. Study 1: In the subjects with hemiplegia, the palsy side had a significantly higher curve index than the non-palsy side (32.7 ± 8.3 vs. 24.4 ± 6.5%). The two sides of the healthy volunteers did not differ significantly in terms of the curve index. Study 2: In all hemiplegia cases, the non-palsy side had a higher pinch strength. The differences were statistically significant (4.40 ± 1.90 vs. 0.05 ± 0.16 kg). In the healthy volunteers, the dominant and non-dominant sides did not differ significantly. Mechanical forces may affect the nail configuration and could participate in the pathophysiology of nail deformities.

    Onychomycosis is a common infection of the toenails that causes nail thickening and discoloration. The physical appearance of the infected nail can diminish self-image and negatively impact quality of life. Patients may use nail polish to mask the appearance of infected nails. To evaluate the in vitro nail penetration properties of tavaborole topical solution, 5%, through nail polish using ex vivo, non-diseased human fingernails. In study 1, tavaborole penetration was evaluated over 20 days of dosing using the Franz finite dose technique and modified Franz diffusion cells. Nails received either 1 coat of over-the-counter (OTC) typical polish or were left unpolished (controls). In study 2, tavaborole penetration was measured over 14 days of dosing using the finite dose technique and vertical diffusion cells. Nails were polished with either 4 coats or 1 coat of salon typical polish or with 2 coats or 1 coat of OTC typical polish, or they were left unpolished. In study 1, the mean ± standard deviation (SD) cumulative tavaborole penetration at day 21 was numerically higher, though not statistically significant, through polished nails (3,526 ± 1,433 μg/cm(2))vs unpolished nails (2,661 ± 1,319 μg/cm(2)).In study 2, the mean cumulative tavaborole penetration was also numerically higher (statistical significance not assessed) through all nails that received polish vs unpolished nails. At day 15, mean ± SD cumulative tavaborole nail penetration was 1,179 ± 554 μg/cm(2) through 4 coats of salon typical polish, 1,227 ± 974 μg/cm(2) through 1 coat of salon typical polish, 1,493 ± 1,322 μg/cm(2) through 2 coats of OTC typical polish, 1,428 ± 841 μg/cm(2) through 1 coat of OTC typical polish, and 566 ± 318 μg/cm(2) through unpolished nails. Results from these in vitro studies demonstrated that tavaborole penetrated through human nails with up to 4 layers of nail polish.

    In the context of the standard SUSY GUT scenario, we present a detailed analysis of the softly broken finite supersymmetric grand unified theory.

    In the context of the standard SUSY GUT scenario, we present a detailed analysis of the softly broken finite supersymmetric grand unified theory. The model, albeit nonminimal, remains very rigid due to the requirement of finiteness. It is based on the SU(5) gauge group and is UV finite to all orders of perturbation theory. It contains three generations of the matter fields together with four pairs of Higgses. The requirement of UV finiteness fixes all the Yukawa couplings at the GUT scale. Imposing the condition of universality on the soft couplings at the Planck scale and then extending the condition of finiteness to them, one gets a completely finite unified theory above MGUT. This makes the fine-tuning procedure more meaningful and leads to the usual Minimal Supersymmetric Standard Model below MGUT. All the masses of the ordinary particles including Higgses are obtained due to the Higgs mechanism at the electro-weak scale. The hierarchy of quark and lepton masses is related to that of v.e.v.'s of the Higgs fields and is governed by the Higgs mixing matrix in the generation space. Superpartners develop their masses according to the RG equations starting from the soft terms at the Planck scale. The suggestion of complete finiteness and maximal simplicity of the unified theory leads to the connection between the initial values of soft SUSY breaking parameters, namely m 02 = {1}/{3}m {1}/{2}2, A t = A b = A τ= -m {1}/{2}, B = -m {1}/{2}, so that the number of free parameters is less than that of the MSSM.

    Full Text Available Congenital micronychia may involve big toes or may involve other nails. The etiology of micronychia is not clear but amniotic bands, teratogens (drugs, alcohol, Nail Patella Syndrome etc. A 44-year-old woman with multiple isolated congenital micronychia over her hands and feet was selected. The major affected nails were thumbs and Index fingers. Surgical method were done step by step: Anesthesia of the area, extraction of short nail, elevation of nail bed, longitudinal nail bed incisions, suturing the lateral nail bed to the nail wall, covering the nail bed by a splint of plastic suction tube, bandage with gauze Vaseline. Finally, we hypnotized that in congenital micronychia, the main pathology is in nail bed; through this theory by nail bed expansion better outcomes are coming.

  9. Review of Proximal Nail Antirotation (PFNA and PFNA-2 – Our Local Experience

    2011-07-01

    Full Text Available The proximal femoral nail antirotation (PFNA device was recently introduced as an option for intramedullary management of pertrochanteric hip fractures. We report here local results with this relatively new implant. Sixty-two patients with pertrochanteric or subtrochanteric fractures underwent intramedullary fixation with PFNA devices in our centre during the 14 month period from September 2008 to October 2009. Data for this report were retrieved from clinical case records and operative notes. We recorded the age, gender, length of stay and operative time, preoperative ambulatory status and days required to regain mobility. Fractures were classified using the AO classification (A1, A2 and A3. Complications were also identified.There were 15 male and 47 female patients and the mean age was 74.3 years. The mean surgical duration was 76.1min and the average length of hospitalisation was 14.5 days. Five cases were noted to have femoral shaft fracture and no occurrences of screw cutout. We found that 83.9% of the patients were able to regain preoperative mobility status by 6 months following surgery. We conclude that the PFNA is an effective implant for stabilisation of proximal hip fractures and that the local complication rate is similar to reports from other centres.

    In this study, a randomized trial was conducted to compare the clinical effectiveness of proximal femoral locking compression plate (PFLCP), dynamic hip screw (DHS), and proximal femoral nail antirotation (PFNA) for unstable intertrochanteric femoral fracture treatment. Ninety patients diagnosed with unstable intertrochanteric femoral fracture were enrolled in this study at the department of orthopedics at Linyi Second People's Hospital between May 2010 and May 2012. Fractures were classified according to Tronzo-Evans classification, and the patients were randomly divided into 3 groups, PFLCP, DHS, and PFNA, with 30 patients in each group. The length of incision, operative time, intraoperative blood loss, postoperative drainage, postoperative weight-bearing ambulation time, and duration of fracture union were significantly lower in patients who underwent PFNA and PFLCP compared to patients treated with DHS. Furthermore, when the same clinical parameters were used for comparison, the PFNA group showed markedly lower values compared with the PFLCP group. The total incidence of postoperative complications was significantly different among the PFNA, PFLCP, and DHS groups, with the PFNA group exhibiting markedly lower complication rates compared with PFLCP and DHS groups. However, PFLCP and DHS groups did not show significant differences in the incidence of postoperative complications. Notably, the Harris hip score of PFNA group was markedly higher than the DHS group. In conclusion, our results provide convincing evidence that PFNA may be the most effective internal fixation treatment of unstable intertrochanteric femoral fracture.

  11. Fractures of the femoral neck.

    Kyle, Richard F

    2009-01-01

    Fractures of the femoral neck are increasing at an exponential rate as a result of the longevity of the general population. The Garden and Pauwels classifications both are routinely used to describe displacement and stability of femoral neck fractures. Osteonecrosis and nonunion remain problematic because of the compromised blood supply to the femoral head in displaced fractures. Nondisplaced fractures and displaced fractures in patients physiologically younger than 65 years are treated with closed or open reduction and internal fixation. Anatomic reduction is the single most important step in the treatment and fixation of these difficult fractures. Because of the higher complication rate in patients physiologically older than 65 years, a prosthetic replacement may be considered for the treatment of displaced fractures. In patients who are low-level community ambulators or nursing home ambulators with comorbidities and who are not expected to live more than 5 years after injury, a hemiprosthesis is indicated. In active, elderly patients physiologically older than 65 years who are expected to live longer than 5 years after injury, a total hip replacement is the treatment of choice. Total hip replacement relieves pain and allows faster rehabilitation than other forms of treatment in this age group. Patients with preexisting hip disease also are treated with total hip replacement. An algorithm that considers physiologic age and activity level of the patient is helpful when deciding whether to fix or replace the hip in a patient with a displaced femoral neck fracture. It is also useful in deciding what type of prosthesis to use. The treatment of femoral neck fractures remains complex and difficult. Because of the enormous burden of this injury, orthopaedists must improve results in the care of femoral neck fractures.

    2001-01-01

    A review of recent results on renormalizations in gauge theories with spontaneously broken supersymmetry is given. It is shown that the renormalizations in a broken theory are completely defined by those in a rigid theory and may be obtained with the help of expansion over the Grassmannian variables. New exact as well as suitable approximate analytic solutions of the renormalization group equations are obtained in some particular models: the Minimal Supersymmetric Standard Model, supersymmetric Grand Unified Theories, softly broken finite theories, and N=2 supersymmetric Seiberg-Witten theory

    Femoral head and neck excision is a surgical procedure that is commonly performed in small animal patients. It is a salvage procedure that is done to relieve pain in the coxofemoral joint and restore acceptable function of the limb. Femoral head and neck excision is most commonly used to treat severe osteoarthritis in the coxofemoral joint and can be done in dogs and cats of any size or age. The procedure should not be overused and ideally should not be done when the integrity of the coxofemoral joint can be restored. Copyright © 2017 Elsevier Inc. All rights reserved.

    2009-10-01

    Transungual delivery of antifungal drugs is hindered by the low permeability of human nail plates, and as such, repeated dosing over a long period of time is necessary for effective treatment. The objectives of this study were to explore the possibilities of (a) enhancing the delivery of ciclopirox (CIC) across human nail plates and (b) sustaining CIC delivery from the larger resultant drug depot in the nail plates with constant voltage iontophoresis. In vitro passive and 9 V cathodal iontophoretic transport experiments of CIC across human nails were performed. Transungual CIC delivery with Penlac was the control. The amounts of CIC released from and deposited in the nails were determined in drug release and extraction experiments, respectively. Iontophoresis increased the flux of CIC permeated across the nail approximately 10 times compared to passive delivery from the same formulation or from Penlac. A significant amount of CIC was loaded into and released from the nails; the CIC concentrations were estimated to be above the minimum inhibitory concentrations of CIC for dermatophytic molds. The apparent transport lag time decreased in iontophoretic transport. The results demonstrate that iontophoresis was able to deliver an effective amount of CIC into and across the nails, and this suggests the feasibility of a constant voltage battery-powered transungual iontophoretic device.

    Onychocryptosis is one of the most common painful nail conditions. Conservative treatment may take a long time to obtain effective results. The purpose of this study is to show the effectiveness of a conservative treatment of ingrown nails that shows rapid results. Patients with painful Stage 1 to 2 onychocryptosis who were not candidates or refused surgery were treated with the cotton cast. The severity and cause of onychocryptosis was clinically evaluated during a 2-month period. A questionnaire was applied to all patients to evaluate pain, final treatment, and possible complications. All patients noticed results in less than 72 hours. Pain subsided in less than 24 hours in half of the patients and before 72 hours in 100% of the patients without the need of other treatments. The use of the cast prevented surgery and the accompanying morbidities in most of the patients (80%). The "cotton nail cast" is an effective conservative method for mild nail embedding. It is easy to apply, inexpensive, relieves pain rapidly, and avoids surgery in most patients.

    Nail has been a substitute DNA source for genotyping. To investigate the integrity and consistency of nail DNA amplification for biomarker study, nail clippings from 12 subjects were collected at monthly intervals. The possibility of longer amplification and existence of GAPDH RNA/protein, were also investigated with three nail samples. Three primer sets were designed for quantitative amplification of nuclear and mitochondrial genes and analysis of their consistency. The mean threshold cycles in amplification of the target genes were compared to test the consistency of polymerase chain reaction (PCR) performance among individual factors including age groups, sex, family, the nail source, and by the size of the amplification segments. The amplification of the target genes from nail DNA showed similar integrity and consistency between the nail sources, and among the serial collections. However, nail DNA from those in their forties showed earlier threshold cycles in amplification than those in their teens or seventies. Mitochondrial DNA (mtDNA) showed better DNA integrity and consistency in amplification of all three targets than did nuclear DNA (nucDNA). Over 9 kb of mtDNA was successfully amplified, and nested quantitative PCR showed reliable copy numbers (%) between the two loci. Reverse transcription PCR for mRNA and immunoblotting for GAPDH protein successfully reflected their corresponding amounts. Regarding the existence of RNA and protein in nails, more effective extraction and detection methods need to be set up to validate the feasibility in biomarker study. Nail DNA might be a feasible intra-individual monitoring biomarker. Considering integrity and consistency in target amplification, mtDNA would be a better target for biomarker research than nucDNA.

    Full Text Available Broken rice is an underutilized by-product of milling. Proteins prepared from broken rice by treatments with alkaline protease and papain have been characterized with regard to nutritional and functional properties. The protein content and the protein recovery were 56.45 and 75.45 % for alkaline protease treatment, and 65.45 and 46.32 % for papain treatment, respectively. Protease treatment increased the lysine and valine content, leading to a more balanced amino acid profile. Broken rice proteins had high emulsifying capacity, 58.3–71.6 % at neutral pH, and adequate water holding capacity, ranging from 1.96 to 2.93 g/g of proteins. At pH=7.0, the broken rice protein had the highest water holding capacity and the best interfacial activities (emulsifying capacity, emulsifying stability, foaming capacity and foaming stability, which may be the result of the higher solubility at pH=7.0. The interfacial activities increased with the increase in the mass fraction of broken rice proteins. The proteins prepared by the papain treatment had higher water holding capacity (p>0.05, emulsifying capacity (p0.05 than alkaline protease treatment at the same pH or mass fraction. To test the fortification of food products with broken rice proteins, pork sausages containing the proteins were prepared. Higher yield of the sausages was obtained with the increased content of broken rice proteins, in the range of 2.0–9.0 %. The results indicate that broken rice proteins have potential to be used as the protein fortification ingredient for food products.

    Background The different treatment strategies for bone cysts in children are often associated with persistence and high recurrence rates of the lesions. The safety and clinical outcomes of a combined mechanical and biological treatment with elastic intramedullary nailing, artificial bone substitute and autologous platelet rich plasma are evaluated. Methods From 02/07 to 01/09 we offered all children with bone cysts the treatment combination of elastic intramedullary nailing (ESIN), artificial bone substitute (Orthoss®) and autologous platelet rich plasma, concentrated by the Gravitational Platelet Separation (GPS®) - System. All patients were reviewed radiologically for one year following the removal of the intramedullary nailing, which was possible because of cyst obliteration. Results A cohort of 12 children (4 girls, 8 boys) was recruited. The mean patient age was 11.4 years (range 7-15 years). The bone defects (ten humeral, two femoral) included eight juvenile and four aneurysmal bone cysts. Five patients suffered from persistent cysts following earlier unsuccessful treatment of humeral bone cyst after pathologic fracture; the other seven presented with acute pathologic fractures. No peri- or postoperative complications occurred. The radiographic findings showed a total resolution of the cysts in ten cases (Capanna Grade 1); in two cases a small residual cyst remained (Capanna Grade 2). The intramedullary nails were removed six to twelve months (mean 7.7) after the operation; in one case, a fourteen year old boy (Capanna Grade 2), required a further application of GPS® and Orthoss® to reach a total resolution of the cyst. At follow-up (20-41 months, mean 31.8 months) all patients showed very good functional results and had returned to sporting activity. No refracture occurred, no further procedure was necessary. Conclusions The combination of elastic intramedullary nailing, artificial bone substitute and autologous platelet rich plasma (GPS®) enhances the

    To compare immediate interlocking nailing with external fixation followed by delayed interlocking nailing, for Gustilo type IIIB open tibial fractures. 23 patients with Gustilo IIIB open tibial fractures were treated with either immediate unreamed interlocking nailing (n=9) or external fixation followed by delayed unreamed interlocking nailing (n=14). Patient age, sex ratio, fracture site, fracture type, and severity were similar in both groups. The time to union, deep infection rate, and nonunion rate in the 2 groups were compared. In the immediate and delayed nailing groups, respective mean times to union were 21 (standard deviation [SD], 14) months and 14 (SD, 8) months; nonunion rates were 44% (4/9) and 36% (5/14), and deep infection rates were 22% (2/9) and 7% (1/14). All corresponding differences were not statistically significant. Prospective, randomised, multicentre studies are needed to assess whether there are significant differences between the 2 treatment methods.

This article presents an analysis of the influence of broken appointment rates on dental students' clinical experience levels. The total percentage of broken appointments experienced by each student from the classes of 2010 and 2011 at Case Western Reserve University School of Dental Medicine during his or her clinical education in the junior and senior years was determined, and the impact of the broken appointment rate on students' clinical experience levels was analyzed. The results show a statistically significant difference regarding the percentage of broken appointments between the classes of 2010 and 2011: 18.64 percent and 14.44 percent, respectively. When the rate of no-shows was compared to the students' clinical experience level, a weak but significant negative correlation was determined for the class of 2010 but not for the class of 2011. It is concluded that the rate of broken appointments accounts for a small part of the variability observed in the number of clinical procedures performed in the predoctoral clinic. When this rate is lowered below a threshold of 14.5 percent, broken appointments seem to have no influence on students' clinical experience level.

    Thirty-five displaced tibial shaft fractures, treated with functional bracing were compared with 43 similar fractures, treated with locked intramedullary nailing. There were 22 excellent/good results in the brace group and 38 in the nail group. There was one infection in the brace group and three in the nailed group. There were five delayed unions and two nonunions in the brace group and one delayed union in the nail group. The functional results in the nailed group were better than the braced group but locked intramedullary nailing of tibial shaft fractures require special resources and training. Locked intramedullary nailing fullfils all the functional criteria for acceptable fracture care.

    The nail with absorbable sheath (AS nail) is designed to reduce the stress shielding effect of internal fixation with interlocking intramedullary nail. In order to verify its feasibility, two types of the finite element models of internal fixation of tibia with the AS nail and the common metal nail (CM nail) are established using the Softwares of Mimics, Geomagic, SolidWorks and ANSYS according to the CT scanning data of tibia. The result of the finite element analysis shows that the AS nail has great advantages compared with the CM nail in reducing the stress shielding effect in different periods of fracture healing. The conclusion is that the AS nail can realize the static fixation to the dynamic fixation from the early to the later automatically to shorten the time of fracture healing, which also provides a new technique to the interlocking intramedullary nail.

    Full Text Available BACKGROUND Fractures of the distal femur present considerable challenges in management. Older patients especially women sustain fractures due to osteoporosis. Supracondylar fractures of femur have a bimodal distribution. They account for 6% of all femur fractures and 31% if hip fractures were excluded. Nearly, 50% of distal femur intra-articular fractures are open fractures. Before 1970, most supracondylar fractures were treated nonoperatively; however, difficulties were often encountered including persistent angulatory deformity, knee joint incongruity, loss of knee motion and delayed mobilisation. The trend of open reduction and internal fixation has become evident in recent years with good results being obtained with AO blade plate, dynamic condylar screw, intramedullary supracondylar nail and locking compression plate. Elderly patients and osteoporosis pose difficulty in treating intra-articular fractures of the lower end of femur. Loss of stable fixation is of great concern in these cases. Hence, locking compression plate use has an advantage in these patients. MATERIALS AND METHODS In this study, 20 patients with closed fracture of distal femur were studied. All the cases were treated at the Department of Orthopaedics, Rangaraya Medical College/Government General Hospital, Kakinada, Andhra Pradesh, between November 2013 and November 2015. The method used for fracture fixation was open reduction and internal fixation with distal femoral locking plate. The duration of follow up ranged from 3 months to 24 months. All the fractures in this series were posttraumatic. The patients were functionally evaluated with Neer’s scoring system. 1 RESULTS Twenty distal femoral fractures were treated with distal femoral locking plates. 15 patients were males and 5 patients were females. The median age was 47 years ranging from 28-70 years. 16 of the fractures were caused by road traffic accidents and 2 were due to fall, 2 were due to assault. 12 patients

    Full Text Available 【Abstract】Objective: Surgical management op-tions for femoral shaft fracture and ipsilateral proximal fe-mur fracture vary from single-implant to double-implant fixation. Cephalomedullary fixation in such fractures has rela-tive advantages over other techniques especially because of less soft tissue dissection and immediate postoperative weight bearing with accelerated rehabilitation. However, the surgery is technically demanding and there is a paucity of literature describing the surgical techniques for this fixation. The aim of the study was to describe the surgical technique of cephalomedullary fixation for femoral shaft fracture and ipsilateral proximal femur fracture. Methods: Sixteen cases (10 males and 6 females with a mean age of 41.8 years of ipsilateral proximal femur and shaft fractures were treated by single-stage cephalomedullary fixa-tion at tertiary level trauma center in northern India. The fractures were classified according to AO classification. An intraoperative record of duration of surgery as well as tech-nical challenges unique to each fracture pattern was kept for all the patients. Results: The most common proximal femoral pattern was AO B2.1 observed in 9 of our patients. The AO B2.3 fractures were seen in 4 patients while the AO A1.2 fractures in 3 patients. Four of the AO B2.1 and 2 of the AO B2.3 frac-tures required open reduction with Watson-Jones approach. The mean operative time was around 78 minutes, which tended to decrease as the surgical experience increased. There was only one case of malreduction, which required revision surgery. Conclusion: Combination of ipsilateral femoral shaft fracture and neck/intertrochanteric fracture is a difficult frac-ture pattern for trauma surgeons. Cephalomedullary nail is an excellent implant for such fractures but it requires careful insertion to avoid complications. Surgery is technically de-manding with a definite learning curve. Nevertheless, a ma-jority of these

    Background: Intramedullary devices have increasingly become popular and are widely used for fixation of unstable intertrochanteric and subtrochanteric fractures. These implants have been designed taking into consideration of the anthropometry of the western population which varies from those of other ethnic groups. This study was carried out to assess the geometry of proximal femur for the placement of short cephalomedullary nails in our subset of patients and suggest suitable design modifications based on these parameters. Materials and Methods: The study was conducted in the following three groups: (1) Anthropometric study of 101 adult human dry femora, (2) radiographs of the same femora, and (3) radiographs of the contralateral uninjured limb of 102 patients with intertrochanteric or subtrochanteric fractures. In Group 1, standard anthropometric techniques were used to measure neck shaft angle (NSA), minimal neck width (NW), trochanteric offset, and distance from the tip of greater trochanter (GT) to the lower border of lesser trochanter on the femoral shaft axis (distance X). In Group 2 and 3, the NSA, minimal NW, NW at 130° and 135°, trochanteric shaft angle (TSA), trochanteric offset, distance X, distance between the tip of GT and the point where the neck axis crosses the line joining the tip of the GT to the lower border of the lesser trochanter on the femoral shaft axis (distance Y), and canal width at 10, 15, and 20 cm from tip of GT were measured on standard radiographs. The values obtained in these three groups were pooled to obtain mean values. Various parameters of commonly used short cephalomedullary nails available for fixation of pertrochanteric fractures were obtained. These were compared to the results obtained to suggest suitable modifications in the nail designs for our subset of patients. Results: The mean parameters observed were as follows: NSA 128.07° ± 4.97 (range 107°–141°), minimum NW 29.0 ± 2.8 mm (range 22–42 mm), NW at 130

    Full Text Available Nail biting (NB is a common, but unresolved, problem in psychiatry, psychology, medicine and dentistry. While it seems that NB is a simple behavior that can be stopped easily, many of the children with NB have already tried to stop it, but they have not been successful. The frustrations due to failed attempt involve others such as parents and siblings. The present review aims at providing an overview of prevalence, co-morbidities, education and counseling, and management for NB. Overall, the reviewed literatures suggest that co-morbidities of psychiatric disorders and other stereotypic behaviors in clinical sample of children with NB is more than 80%, and more than half of the parents suffer from psychiatric disorders mainly depression. Treatment of NB, however, is not as easy as it seems. The management of NB is much more complicated than just focusing on stopping it. Nail biting cannot be managed without considering its co-morbidities, antecedents and consequences. It might be concluded form the reviewed literature that children with NB, parents, siblings, and teachers should be educated about what to do and what not to do about NB. Punishment is not effective. Moreover, clinical randomized controlled trials are required to make available evidence-based behavioral and pharmacologic treatment protocols

    Over the past few years, there has been an increase in cases of allergic contact dermatitis caused by acrylates, because of the growing popularity of artificial nails. Pathological reactions to artificial nails typically occur on or around the nail area. Eyelid contact dermatitis due to artificial nails is rarely seen, especially in a nonoccupational setting. The authors report the case of a 45-year-old female accountant who developed eyelid dermatitis due to artificial nails.

  11. Enhancing the nail permeability of topically applied drugs.

    The topical therapy of nail diseases, especially of onychomycosis, and to a smaller extent, of nail psoriasis, is desirable to avoid the side effects associated with their systemic therapy, to increase patient compliance and reduce the cost of treatment. Systemic therapy is however the mainstay of treatment due to the poor permeability of the nail plate to topically applied drugs. For effective topical therapy, ungual drug permeation must be enhanced. This can be achieved by disrupting the nail plate using physical techniques or chemical agents. Alternatively, drug permeation into the intact nail plate may be encouraged, for example, by iontophoresis or by formulating the drug within a vehicle which enables high drug partition out of the vehicle and into the nail plate. The physical techniques (manual and electrical nail abrasion, acid etching, ablation by lasers, microporation, application of low-frequency ultrasound and electric currents) and chemicals (thiols, sulphites, hydrogen peroxide, urea, water, enzymes) that have shown ungual enhancer activity are discussed in this review. Optimal drug formulation, while crucial to ungual drug delivery, is only briefly reviewed due to the limited literature.

    The objective of this study was to develop an initial lexicon for sensory properties of nail polish and to validate this lexicon using a descriptive analysis study of selected samples. Seventeen commercial products from four categories (regular, flake-containing, water-based and gel) were used in this study. Descriptive sensory analysis was conducted in this study to characterize and evaluate application and removal properties of these nail polishes. Data was then processed by ANOVA, Principal Component Analysis (PCA) and Pearson's Correlation Coefficient analysis to explore the differences among samples and attributes. A lexicon of 21 sensory attributes was developed to describe the application of nail polish. It included three initial texture attributes, thirteen initial appearance attributes and five aroma attributes. A lexicon of five attributes in five stages was developed to describe the removal of nail polish. The results from ANOVA and PCA showed that attributes in the lexicon separated the different product categories. The results of this study indicated that descriptive sensory analysis can be used to evaluate nail polish. The results of this study present scientists who are working on nail polish an additional tool to describe application and removal properties of nail polish. © 2014 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    To investigate the outcomes of arthroscopic femoral neck osteoplasty in patients with slipped capital femoral epiphysis (SCFE)-related impingement. We retrospectively reviewed 37 consecutive patients (40 hips; 19 male and 18 female patients; age range, 10 to 19 years) with SCFE who underwent hip arthroscopy for femoral neck osteoplasty over a 4-year period. Six hips were excluded because of the severity of the slip or conversion to an open procedure. The preoperative and postoperative slip angle, alpha angle, and internal rotation in flexion were compared. Patients were evaluated for pain, functional limitations, and obligatory external rotation deformity (OERD) at each follow-up visit. The mean follow-up period was 22 months (range, 12 to 56 months). We analyzed the results of 34 hips. Adequate distraction could not be obtained initially in 7 hips. The labral and acetabular cartilage damage appeared to be from crushing and abrasion from the bony prominence of the neck. The goals of complete pain relief and correction of OERD were achieved in 88% of the hips. OERD and pain persisted in 2 hips, and 2 patients had residual pain despite good motion. There was a statistically significant improvement in alpha angle (from 88.22° and 56.91°, P femoral neck osteoplasty is effective in decreasing pain, the alpha angle, and OERD in mild to moderate SCFE. Morbid obesity, scarring from previous surgery, and the presence of screws in the anterior neck presented challenges to the arthroscopic technique. Level IV, therapeutic case series.

    ). Fragment B seems to have fragmented again, bringing the total of fragments close to 40, some being most probably very small, boulder-sized objects with irregular and short-lived activity. The new observations reveal that this new small fragment has split again! The image clearly reveals that below the main B fragment, there is a small fragment that is divided into two and a careful analysis reveals five more tiny fragments almost aligned. Thus, this image alone shows at least 7 fragments. The comet has thus produced a whole set of mini-comets! ESO PR Photo 15b/06 ESO PR Photo 15b/06 Broken Fragments of Comet SW-3 Will the process continue? Will more and more fragments form and will the comet finally disintegrate? How bright will the fragments be when the comet will be the closest to the Earth, on 11 to 14 May, and how many new fragments will have appeared before the comet reaches its closest approach to the Sun, around 7 June? Fragment C of the comet should be the closest to Earth on 11 May, when it will be about 12 million km away, while fragment B will come as 'close' as 10 million km from Earth on 14 May. Although this is the closest a comet ever approached Earth in more than twenty years - even Comet Hyakutake's smallest distance was 15 million km - this is still 26 times the distance between the Earth and the Moon and therefore does not pose any threat to our planet. ESO PR Photo 15/06 ESO PR Photo 15c/06 Mini-Comets coming off Comet SW-3 If nothing else happens, at the time of closest approach, fragment B will be just visible with unaided eye by experienced observers. It should be an easy target however to observe with binoculars. If we are lucky, however, fragment B presents another outburst, becoming a magnificent sight in the night sky. On the other hand, it could just as well fade away into oblivion. But then, the main fragment C should still be visible, even possibly with the unaided eye.

    Acrylates are molecules that are well known for their strong sensitizing properties. Historically, many beauticians and individuals using store-bought artificial nail products have developed allergic contact dermatitis from acrylates. More recently, the use of acrylic nails among flamenco guitarists to strengthen their nails has become very popular. A 40-year-old non-atopic male patient working as a flamenco guitarist developed dystrophy, onycholysis and paronychia involving the first four nails of his right hand. The lesions were confined to the fingers where acrylic materials were used in order to strengthen his nails to play the guitar. He noticed improvement whenever he stopped using these materials and intense itching and worsening when he began reusing them. Patch tests were performed and positive results obtained with 2-hydroxyethyl methacrylate (2-HEMA), 2-hydroxyethyl acrylate (2-HEA), ethyleneglycol-dimethacrylate (EGDMA) and 2-hydroxypropyl methacrylate (2-HPMA). The patient was diagnosed with occupational allergic contact dermatitis likely caused by acrylic nails. Artificial nails can contain many kinds of acrylic monomers but most cases of contact dermatitis are induced by 2-HEMA, 2-HPMA and EGDMA. This is the first reported case of occupational allergic contact dermatitis from acrylates in artificial nails in a professional flamenco guitar player. Since the practice of self-applying acrylic nail products is becoming very popular within flamenco musicians, we believe that dermatology and occupational medicine specialists should be made aware of the potentially increasing risk of sensitization from acrylates in this setting. © The Author 2016.

  16. Finger Tendon Travel Associated with Sequential Trigger Nail Gun Use

    2015-01-01

    TECHNICAL ABSTRACT Background Pneumatic nail guns used in wood framing are equipped with one of two triggering mechanisms. Sequential actuation triggers have been shown to be a safer alternative to contact actuation triggers because they reduce traumatic injury risk. However, the sequential actuation trigger must be depressed for each individual nail fired as opposed to the contact actuation trigger, which allows the trigger to be held depressed as nails are fired repeatedly by bumping the safety tip against the workpiece. As such, concerns have been raised about risks for cumulative trauma injury, and reduced productivity, due to repetitive finger motion with the sequential actuation trigger. Purpose This study developed a method to predict cumulative finger flexor tendon travel associated with the sequential actuation trigger nail gun from finger joint kinematics measured in the trigger actuation and productivity standards for wood-frame construction tasks. Methods Finger motions were measured from six users wearing an instrumented electrogoniometer glove in a simulation of two common framing tasks–wall building and flat nailing of material. Flexor tendon travel was calculated from the ensemble average kinematics for an individual nail fired. Results Finger flexor tendon travel was attributable mostly to proximal interphalangeal and distal interphalangeal joint motion. Tendon travel per nail fired appeared to be slightly greater for a wall-building task than a flat nailing task. The present study data, in combination with construction industry productivity standards, suggest that a high-production workday would be associated with less than 60 m/day cumulative tendon travel per worker (based on 1700 trigger presses/day). Conclusion and Applications These results suggest that exposure to finger tendon travel from sequential actuation trigger nail gun use may be below levels that have been previously associated with high musculoskeletal disorder risk.

    Interest is growing in non-invasive diagnostic methods for nails in dermatological pathology. Currently, nail disease diagnosis is based mostly on clinical evaluation; instrumental examination, traditionally, has been performed by magnetic resonance. Ultrasound (US) can be proposed as an easier and more available method for the study of the nail apparatus. In this study, the nail unit normal ultrasound anatomy was investigated to obtain data on adult normal parameters. On 35 healthy volunteers (20 women and 15 men--average age of 27 years) we performed an ultrasonographic study on the nail plate (dorsal and ventral), nail matrix and nail bed of all fingers of the hands using a 18 MHz linear transducer with Esaote Mylab 50. A thick gel layer allowed for appropriate transmission of ultrasound without any additional device. Macroscopic nail features were studied by clinical examination and photographic analysis. The following ultrasound parameters were investigated: nail thickness; nail bed thickness; matrix lenght; matrix-bone distance. Blood flow was studied with the use of colour and power colour Doppler. The nail apparatus echographic anatomy consists in: (a) nail plate, represented by two hyperechoic bands (dorsal and ventral) with an hypoechoic or anechoic space between them; (b) nail bed, represented by an area of dys-homogeneous hypo-echogeneity; (c) nail matrix, represented by a markedly hypoechoic area corresponding to the region under the nail sulcus; (d) ligaments, sometimes well detectable and formed by a specialized connective tissue; and (e) vessels, well evaluable through doppler examination.

    The influence of diabetes mellitus on dielectric properties of the human fingernail was measured in vitro in the alpha-dispersion region. The frequency dependencies of the permittivity and conductivity for the healthy and the diabetic nail plate revealed three separate relaxations, which were similar for both materials. Significant differences were observed in the values of permittivity at the same frequency between the healthy and the diabetic nails with low water content of about 0% and 3%. Results of this paper suggest that hyperglycemia alters the first-order structure of the nail keratin macromolecule.

    Full Text Available Subungual pigmentation may have a variety of underlying pathologies, but clinicians should consider malignancies such as subungual melanoma or metastasis, even if they are not common. A delayed diagnosis can dramatically worsen the prognosis. Therefore, histologic examination is highly recommended. We present a 75-year-old female cancer patient presenting with subungual blackish pigmentation of the great toe nail for several years suspicious of a subungual melanoma even by dermoscopy. Nail avulsion and histological investigations excluded melanoma. The final diagnosis was subungual hematoma with growth malalignment of the great toe nail.

Histopathological examination of the macule showed vacuolization of the basal layer, melanophages in the superficial dermis and lymphoplasmocytic inflammatory infiltrate. Nail biopsy revealed orthokeratotic hyperkeratosis and lichenoid inflammatory infiltrate. Lichen planus pigmentosus is an uncommon variety of lichen planus. It is characterized by typical hyperpigmented macules on the face and neck. Nail changes might be present in 10% of lichen planus cases, but no associations with lichen planus pigmentosus have been described. We report a case of lichen planus in twenty nails associated with lichen planus pigmentosus on the patient's face.

    Subungual melanoma is an uncommon type of melanoma that can be difficult to diagnose. Patients often present with advanced primary lesions and have an associated increased risk of nodal disease. Delays in diagnosis are believed to contribute to poor patient outcomes. The objective of this article is to offer an approach to assessing and managing patients who present with subungual pigmented lesions. We describe the anatomy of the nail bed to offer a rationale for our technique of nail bed biopsy, and warn of the potential to cause permanent nail dystrophy through other approaches. Many clinicians have limited experience in assessing lesions of the nail apparatus.Subungual pigmentation has extremely broad differential diagnoses, which include a variety of benign pathologies. A systematic approach to assessment, and early referral of patients with suspicious lesions to a specialist unit, has the potential to improve patient outcomes.

    Full Text Available This paper presents a strength analysis of a calcaneal nail (material Ti6Al4V and stainless steel which is used to treat complex heel fractures. The application focuses on a unique calcaneal nail, the C-NAIL, produced by Medin a.s. (Nové Město na Moravě, Czech Republic. The paper first presents an analysis of fracture types, treatment methods and loading of the calcaneus. It then presents an analysis of limit conditions and loading. Calculations (displacement and stress are performed for 6 and 7 fixing screws using FEM (Ansys Workbench 14 software. The calculation involves a new, original application of an elastic foundation, which effectively replaces the complex interaction of the calcaneal nail and the heel bone.

  10. Experimental Study on the Porosity Creep Properties of Broken Limestone

    Full Text Available In the underground engineering, the long-term stability of the surrounding rocks (especially the broken rocks containing water and the ground settlement resulted from the seepage-creep coupling above goaf have been the important research subjects concerning the deep mining. For the broken rock, its porosity is an important structural parameter determining its creep properties, and the porosity change rate is more superior to describe the creep characteristics compared with the strain change rate at a certain direction. In this paper, MTS815.02 Rock Mechanics Test System is used to carry out the creep experiments on water-saturated broken limestone, and then the time curves of porosity and of the porosity change rate are obtained. By regression, we have got the relation equation between the porosity change rate with the instant porosity and the stress level during the creep. The study indicates that when the stress retains a constant level, the relation between the porosity change rate and the instant porosity can be fitted with a cubical polynomial. The obtained creep relation equation between the porosity change rate and the instant porosity and the instant stress provides a necessary state equation for studying the coupling between the seepage and the creep of the broken rock. Furthermore, the seepage in the broken rock has been verified to satisfy the Forchheimer’s non-Darcy flow according to our previous studies, and its seepage properties, k, β and ca can all be expressed respectively as the polynomial of the porosity, so, by combining with these three state equations we have obtained the four essential state equations for solving the coupling problems of the seepage and the creep for the broken rocks.

    Purpose: We investigated the clinical and dosimetric predictors for radiation-associated femoral fractures in patients with proximal lower extremity soft tissue sarcomas (STS). Methods and Materials: We examined 131 patients with proximal lower extremity STS who received limb-sparing surgery and external-beam radiation therapy between 1985 and 2006. Five (4%) patients sustained pathologic femoral fractures. Dosimetric analysis was limited to 4 fracture patients with full three-dimensional dose information, who were compared with 59 nonfracture patients. The mean doses and volumes of bone (V{sub d}) receiving specified doses ({>=}30 Gy, 45 Gy, 60 Gy) at the femoral body, femoral neck, intertrochanteric region, and subtrochanteric region were compared. Clinical predictive factors were also evaluated. Results: Of 4 fracture patients in our dosimetric series, there were three femoral neck fractures with a mean dose of 57.6 {+-} 8.9 Gy, V30 of 14.5 {+-} 2.3 cc, V45 of 11.8 {+-} 1.1 cc, and V60 of 7.2 {+-} 2.2 cc at the femoral neck compared with 22.9 {+-} 20.8 Gy, 4.8 {+-} 5.6 cc, 2.5 {+-} 3.9 cc, and 0.8 {+-} 2.7 cc, respectively, for nonfracture patients (p < 0.03 for all). The femoral neck fracture rate was higher than at the subtrochanteric region despite lower mean doses at these subregions. All fracture sites received mean doses greater than 40 Gy. Also, with our policy of prophylactic femoral intramedullary nailing for high-risk patients, there was no significant difference in fracture rates between patients with and without periosteal excision. There were no significant differences in age, sex, tumor size, timing of radiation therapy, and use of chemotherapy between fracture and nonfracture patients. Conclusions: These dose-volume toxicity relationships provide RT optimization goals to guide future efforts for reducing pathologic fracture rates. Prophylactic femoral intramedullary nailing may also reduce fracture risk for susceptible patients.

    Passive diffusion data for uncharged solutes in hydrated human nail plate are collected and compared to the predictions of two theories for diffusion of uncharged solutes in dense keratin matrices. Quantitative agreement between the experimental data and the theories examined is poor. Concerns with both the experiments and the theories are identified and discussed. It is evident from the analysis that magnitude of the experimental nail permeability data may be questioned, as...

    Nail procedures require an effective and reliable approach to anesthesia of the distal digit. Several techniques have been described in the literature. Herein, the relevant anatomy of the nail unit, pain pathways, anesthetic options, and several injection approaches to achieve complete anesthesia are reviewed. Also considered are the potential pitfalls and complications and their management. Ultimately, the physician's approach must be individualized to the patient, procedure, and setting.

    Background and Design: One of the reasons for preferring conservative methods for ingrown nails is lack of local anesthesia for the painful step. Moreover, ingrown nail is a painful condition per se. It may be very difficult to intervene patients with high basal pain levels. Here, we aimed to assess the efficacy of topical anesthetics (2.5% lidocaine, 2.5% prilocaine mixture and 20% benzocaine gel) by determining basal pain level and pain during and after manipulation in patients with severe ...

    2002-01-01

    BACKGROUND: Small case series have suggested an increased risk of femoral hernia after previous inguinal herniorrhaphy, but no large-scale data with complete follow-up are available. METHODS: Data were extracted from the Danish Hernia Database covering the interval from 1 January 1998 to 1 July...... 2001, and included 34 849 groin hernia repairs. RESULTS: Of 1297 femoral hernia repairs, 71 patients had previously had an operation for inguinal hernia within the observation period. These 71 femoral hernias represented 7.9 per cent of all reoperations for groin hernia recorded in the database....... The median time to reoperation for a 'recurrent' femoral hernia after previous inguinal herniorrhaphy was 7 months, compared with 10 months for inguinal recurrences. The risk of developing a 'recurrent' femoral hernia after previous inguinal herniorrhaphy was 15 times higher than the rate of femoral hernia...

  18. Arteriosclerotic femoral artery aneurysms. A short review

    True arteriosclerotic aneurysms of the femoral artery are rare but they are dangerous lesions that may thrombose, embolise or rupture. They are often bilateral and frequently the patient has other aneurysms in the abdominal aortic or popliteal artery. True femoral aneurysms were originally...... classified by Cutler and Darling in 1973 as type 1 and type 2 according to their relationship to the common femoral bifurcation. Case reports of isolated superficial and profunda femoral artery aneurysms have been published, but these are exceedingly rare although isolated aneurysms of the profunda femoris...... artery may be more common in Denmark. True femoral artery aneurysms are attributed to weakening of the arterial wall due to atherosclerosis. True femoral artery aneurysms are relatively rare and are found in elderly smoking men. Aortic aneurysms are approximately 10 times more common. Distal embolization...

    In a retrospective review of 43 femoral fractures, three dogs had separation of the femoral capital epiphysis from the metaphysis in the absence of trauma. Two of these dogs also had evidence of pathology in the contralateral femoral neck including, in one dog, displacement of the capital epiphysis in relation to the metaphysis without actual separation. The case histories, radiographic features and histopathological findings of these cases were reviewed and compared with previous cases of slipped capital femoral epiphysis (SCFE) reported in dogs and also with SCFE in children. Pre-slip, acute, chronic and acute-on-chronic slips were Identified. Based on the cases reviewed, the authors advise internal fixation of stable slipped epiphyses in dogs. This may also be appropriate for unstable separations, although resorption of the femoral neck may preclude stable fixation and necessitate femoral head and neck excision.

    The aim of study was to test, for the presence of osteoblasts in the reaming debris of intramedullary nailing of femoral and tibial fracture in patients with and without severe head injury. Two groups of patients were studied. Group A (n = 32) had long bone fractures in addition to having head injuries. Group B (n = 35) had only long bone fractures. The fractures in the 2 groups of patients was treated by inter medullary nailing. Osteoblasts in the debris of the inter medullary nailing was compared between the 2 groups of patients. The results demonstrated that histopathological specimens from reaming debris of fractured femur and tibia in patients with head injury showed osteoblasts in (82.9%) and in (27.5%) of patients with isolated long bone fractures (p fractures and concomitant head injury confirm fast and adequate healing in these patients and the presence of plenty of osteoblasts in their reaming debris may reflect a proof of accelerated fracture healing environment.
