Gluteal muscle fibrosis with hip contracture is a rare condition and causes major disability; literature reports are sparse. The aim of this study is to present, for the first time in Iraq and the region, a case series of gluteal fibrosis and the results of surgical treatment. Seven children--six boys and one girl--diagnosed as having gluteal muscle fibrosis with hip contracture, were investigated and treated by open surgical release of fibrotic bands and physiotherapy. All patients improved dramatically over the subsequent weeks, and were able to sit and squat in the normal position. Gluteal muscle fibrosis with hip contracture is present in Iraq and more awareness is needed for early diagnosis. Surgical treatment provided excellent results. More studies are needed to delineate the aetiology of the condition.

We present 5 cases of adult hips flexion due to neurological conditions treated following our algorithm. At 1-year-follow-up all patients had a good clinical outcome in terms of hip range of motion, pain and recovery of walking if possible. In conclusion we think that this algorithm could be a good guideline to treat these complex cases even if we need to treat more patients to confirm this theory. We believe also that postoperation physiotherapy it is useful in hip motility preservation, improvement of muscular function, and walking ability recovery when possible.

Full Text Available Coxa obliqua represents a special functional entity in the pathology of the child hip. Authors have confirmed the results of S.L. Weissman and B. Strinovic which claimed that the abductor contracture of the hip was a primary congenital condition that developed as a result of intrauterine malposition, leading later to the contralateral adductor contracture. Critical period for the development of complications was between 6 and 8 month after birth, adductor contracture might keep persisting together with the development of acetabular dysplasia, and later on with ipsilateral subluxation. This malformation has usually been diagnosed within 3 and 6 months of age. It could be connected with some other signs of malposition, such as plagiocephaly, torticollis or infantile thoracic C scoliosis. For the diagnosis of coxa obliqua, the examination of hips in the prone position was very important and the ultrasonic and radiological examinations were crucial. The applied treatment used to be exclusively physical rehabilitation. Wide diapering has been contraindicated. In this study, we included 2,500 newborns, 1,300 boys and 1,200 girls (5,000 hips. In 22 cases of coxa obliqua (10‰, the excellent results were obtained in 96% of cases. In two unsuccessfully treated cases, a contralateral dysplasia developed, and in one untreated, subluxation. The authors are advocating a systematic and early detection and treatment of the primary coxa obliqua. .

Full Text Available Abstract Background Psoas contracture is known to cause abnormal hip motion in patients with cerebral palsy. The authors investigated the clinical relevance of hip kinematic and kinetic parameters, and 3D modeled psoas length in terms of discriminant validty, convergent validity, and responsiveness. Methods Twenty-four patients with cerebral palsy (mean age 6.9 years and 28 normal children (mean age 7.6 years were included. Kinematic and kinetic data were obtained by three dimensional gait analysis, and psoas lengths were determined using a musculoskeletal modeling technique. Validity of the hip parameters were evaluated. Results In discriminant validity, maximum psoas length (effect size r = 0.740, maximum pelvic tilt (0.710, maximum hip flexion in late swing (0.728, maximum hip extension in stance (0.743, and hip flexor index (0.792 showed favorable discriminant ability between the normal controls and the patients. In convergent validity, maximum psoas length was not significantly correlated with maximum hip extension in stance in control group whereas it was correlated with maximum hip extension in stance (r = -0.933, p Conclusions Maximum pelvic tilt, maximum psoas length, hip flexor index, and maximum hip extension in stance were found to be clinically relevant parameters in evaluating hip flexor contracture.

Contractures of a major joint in the lower limbs may impair human walking in addition to other daily living activities. A contracture is defined as the inability of a joint to perform the full range of motion and excessive resistance during passive mobilization of the joint. Few studies have reported methods describing how to evaluate contractures. Understanding the association among all of these studies seems essential to improve patient management. Therefore, we conducted a systematic review on this topic to elucidate the influence of contractures on gait kinematics. An electronic search in the literature will be conducted. Studies were screened by title and abstract and full texts were evaluated secondarily for definitive inclusion. The quality of the included studies was assessed independently by the two review authors with the Modified Quality Assessment Checklist. The included studies were separated into three categories: pathological contracture versus healthy controls (descriptive), simulated contracture versus healthy controls (experimental), and pre- and post-kinematics after surgical muscle lengthening (surgery). From a total of 4402 references, 112 original articles were selected, and 28 studies were identified in this systematic review. No significant difference between raters was observed on the total score of the Modified Quality Assessment Checklist. Contractures influence walking depending on the location (muscle) and the contracture level (muscle-tendon length). After giving a definition of contracture, this review identified some contracture alterations, such as plantarflexion, knee flexion and hip flexion contractures, with a kinematic description and presented possible different compensations.

Contracture is a permanent shortening of the muscle-tendon-ligament complex that limits joint mobility. Contracture is involved in many diseases (cerebral palsy, stroke, etc.) and can impair walking and other activities of daily living. The purpose of this study was to quantify the reliability of an exoskeleton designed to emulate lower limb muscle contractures unilaterally and bilaterally during walking. An exoskeleton was built according to the following design criteria: adjustable to different morphologies; respect of the principal lines of muscular actions; placement of reflective markers on anatomical landmarks; and the ability to replicate the contractures of eight muscles of the lower limb unilaterally and bilaterally (psoas, rectus femoris, hamstring, hip adductors, gastrocnemius, soleus, tibialis posterior, and peroneus). Sixteen combinations of contractures were emulated on the unilateral and bilateral muscles of nine healthy participants. Two sessions of gait analysis were performed at weekly intervals to assess the reliability of the emulated contractures. Discrete variables were extracted from the kinematics to analyse the reliability. The exoskeleton did not affect normal walking when contractures were not emulated. Kinematic reliability varied from poor to excellent depending on the targeted muscle. Reliability was good for the bilateral and unilateral gastrocnemius, soleus, and tibialis posterior as well as the bilateral hamstring and unilateral hip adductors. The exoskeleton can be used to replicate contracture on healthy participants. The exoskeleton will allow us to differentiate primary and compensatory effects of muscle contractures on gait kinematics. Copyright © 2016 Elsevier B.V. All rights reserved.

To review the records of 363 patients with severe gluteal muscle contracture to determine its mechanism, underlying pathology, and treatment outcome. Records of 136 males and 227 females aged 5 to 18 (mean, 12.2) years who underwent Z-plasty for bilateral (n=347) or unilateral (n=16) severe gluteal muscle contracture were reviewed. Severe gluteal muscle contracture was classified as typical (n=52) or special (n=311). The typical type is associated with symptoms of positive out-toe gait, Ober sign, back-extending test, cross-leg test, squatting with knee side-by-side test, and hip dysfunction. It is further subdivided into mild (n=0), moderate (n=40), or severe (n=12). The special type is associated with additional symptoms of pelvic tilt and leg length discrepancy (4 cm in 48 hips). 311 hips had pelvic tilt and 47 hips had lumbar compensatory scoliosis. Treatment outcome was assessed at 6 months. Hip functional score was assessed at the final follow-up. The mean hospitalisation period was 11 days. After a mean follow-up of 1.5 years, the mean hip functional score improved from 8.03 to 11.69; improvement was higher in children (age 5-13 years) than in adolescents (age 14-18 years) [3.7 vs. 2.9, p4 cm, and intra-operatively the contracture band severely affected the joint capsule. The third patient did not comply with postoperative exercises. Surgical treatment for severe gluteal muscle contracture achieved good outcome.

Contractures are one of a handful of signs in muscle disease, besides weakness and its distribution, whose presence can help guide us diagnostically, a welcome star on the horizon. Contractures are associated with several myopathies, some with important cardiac manifestations, and consequently are important to recognise; their presence may also provide us with a potential satisfying 'penny dropping' diagnostic moment.

Full Text Available We report the case of a 3-1/2-year-old girl with hypotonia, multiple joint contractures, hip luxation, arachnodactyly, adducted thumbs, dolichostenomelia, and abnormal external ears suggesting the diagnosis of congenital contractural arachnodactyly (CCA. The serum muscle enzimes were normal and the needle electromyography showed active and chronic denervation. The muscle biopsy demonstrated active and chronic denervation compatible with spinal muscular atrophy. Analysis of exons 7 and 8 of survival motor neuron gene through polymerase chain reaction did not show deletions. Neurogenic muscular atrophy is a new abnormality associated with CCA, suggesting that CCA is clinically heterogeneous.

Deltoid contracture is relatively uncommon. The literature consists primarily of case reports and few articles on large case series. The pathogenesis has been well studied. Muscle contractures can occur in the deltoid, biceps, triceps, gluteus and quadriceps muscles; however, cases of multiple muscle contractures are rare. We reported a patient with multiple contractures of the bilateral deltoid, bilateral gluteus, and bilateral quadriceps muscles, who had received repeated intramuscular injections during childhood and adulthood. The radiographic, including magnetic resonance imaging (MRI), features of the bone and joint abnormalities are presented. Some literatures reported that damage to the structures of the body due to intramuscular injection is related to the site of injection, age of the patient, and the volume, pH, chemical composition, and diffusional capacity of the injectate. Our patient had muscular contracture induced by needle injection regardless of her age, medication and injection site.

Gluteal muscle contracture is a clinical syndrome that involves contracture and distortion of the gluteal muscles and fascia fibers due to multiple causes. Physical examination demonstrates a characteristic gait due to hip adduction and internal thigh rotation. This study introduces a new minimally invasive method for surgical release of gluteal muscle contracture. Patients with gluteal muscle contracture were assigned to 4 categories: type A, contracture occurred mainly in the iliotibial tract; type B, contracture occurred in the Iliotibial tract and gluteus maximus; type C1, movement of the contraction band was palpable and a snapping sound was audible during squatting; and type C2, movement of the contraction band was not palpable or almost absent and a snapping sound was audible during squatting. This classification method allowed prediction of the anatomic location of these pathological contractures and determination of the type of surgery required. Four critical points were used to define the operative field and served as points to mark a surgical incision smaller than 4 mm. The contracture was easily released in this carefully marked operative field without causing significant neurovascular damage. Over a period of 5 years, between March 2003 and June 2008, the authors treated 1059 patients with this method and achieved excellent outcomes. Most patients were fully active within 12 weeks, with the assistance of an early postoperative rehabilitation program. The most significant complication was a postoperative periarticular hematoma, which occurred in 3 patients within 10 days postoperatively and required surgical ligation of the bleeding vessel.

Contractures of the intrinsic muscles of the fingers disrupt the delicate and complex balance of intrinsic and extrinsic muscles, which allows the hand to be so versatile and functional. The loss of muscle function primarily affects the interphalangeal joints but also may affect etacarpophalangeal joints. The resulting clinical picture is often termed, intrinsic contracture or intrinsic-plus hand. Disruption of the balance between intrinsic and extrinsic muscles has many causes and may be secondary to changes within the intrinsic musculature or the tendon unit. This article reviews diagnosis, etiology, and treatment algorithms in the management of intrinsic contractures of the fingers. Copyright © 2012 Elsevier Inc. All rights reserved.

To investigate clinical curative effects of gluteal muscle contracture release combined with insertion of gluteus maximus tendo-chilles lengthening with Z-shaped in treating severe gluteal muscles contracture. From 2006 May to 2011 May, 20 patients (35 sides) with severe gluteal muscle contracture were collected, including 12 males and 8 females, aged from 8 to 34 years old with an average of 13 years old; the courses of disease ranged from 3 to 21 years. All patients manifested abnormal gait at different degree, knees close together cannot squat,positive syndrome of Ober, positive test of alice leg. Gluteus contracture fascia release were performed firstly in operation, then insertion of tendo-chilles lengthening with Z-shaped were carried out. Preoperative and postoperative gait, and knee flexion hip extensor squat test, cross leg test, adduction and internal rotary activity of hip joint, stretch strength and motor ability after hip abduction were observed and compared. Twenty patients were followed up for 1 to 5 years. Gluteus maximus were released thoroughly, and snapping hip was disappeared, Ober syndrome were negative. There was significant differences in knee flexion hip extensor squat test, adduction and internal rotary activity of hip joint,stretch before and after operation (Pmuscle strength was protected,stretch strength and motor ability of hip joint were recovered well. Among them,31 cases got excellent results and 4 good. For severe gluteal muscles contracture,insertion of gluteus maximus tendo-chilles lengthening with Z-shaped performed after gluteus contracture fascia release could release gluteal muscle contracture to the greatest extent and obtain postoperative curative effect without resection of normal hip muscle fibers and destroy joint capsule.

Ankle plantarflexion contracture results from a permanent shortening of the muscle-tendon complex. It often leads to gait alterations. The objective of this study was to compare the kinematic adaptations of different degrees of contractures and between isolated bilateral gastrocnemius and soleus emulated contractures using an exoskeleton. Eight combinations of contractures were emulated bilaterally on 10 asymptomatic participants using an exoskeleton that was able to emulate different degrees of contracture of gastrocnemius (biarticular muscle) and soleus (monoarticular muscle), corresponding at 0°, 10°, 20°, and 30° ankle plantarflexion contracture (knee-flexed and knee-extended). Range of motion was limited by ropes attached for soleus on heel and below the knee and for gastrocnemius on heel and above the knee. A gait analysis session was performed to evaluate the effect of these different emulated contractures on the Gait Profile Score, walking speed and gait kinematics. Gastrocnemius and soleus contractures influence gait kinematics, with an increase of the Gait Profile Score. Significant differences were found in the kinematics of the ankles, knees and hips. Contractures of soleus cause a more important decrease in the range of motion at the ankle than the same degree of gastrocnemius contractures. Gastrocnemius contractures cause greater knee flexion (during the stance phase) and hip flexion (during all the gait cycle) than the same level of soleus contractures. These results can support the interpretation of the Clinical Gait Analysis data by providing a better understanding of the effect of isolate contracture of soleus and gastrocnemius on gait kinematics.

Isolated adrenocorticotropic hormone deficiency (IAD) is a rare disorder with diverse clinical presentations. A 79-year-old man was bedridden for six months due to flexion contractures of the bilateral hips and knees, along with hyponatremia. He was diagnosed with IAD based on the results of endocrine tests. After one month of corticosteroid replacement, he recovered and was able to stand up by himself. Although flexion contracture is a rare symptom of IAD, steroid replacement therapy may be effective, even for seemingly irreversibly bedridden elderly patients. In bedridden elderly patients with flexion contractures, we should consider and look for any signs of adrenal insufficiency. PMID:27746435

What is the incidence of contractures six months after stroke? Can factors measured within four weeks of stroke predict the development of elbow, wrist, and ankle contractures six months later? Prospective cohort study. Consecutive sample of 200 adults with stroke admitted to a Sydney hospital. Loss of range of motion in major joints of the body was measured using a 4-point ordinal contracture scale. In addition, elbow extension, wrist extension, and ankle dorsiflexion range of motion were measured using torque-controlled procedures. Potential predictors of contracture were age, pre-morbid function, severity of stroke, muscle strength, spasticity, motor function, and pain. Measurements were obtained within four weeks of stroke and at six months after stroke. 52% of participants developed at least one contracture. Incidence of contracture varied across joints from 12% to 28%; shoulders and hips were most commonly affected. Muscle strength was a significant predictor of elbow, wrist, and ankle joint range. Prediction models explained only 6% to 20% of variance in elbow, wrist, and ankle joint range. About half of all patients with stroke develop at least one contracture within six months of stroke. Incidence of contractures across all joints ranged from 12% to 28%. Muscle strength is a significant predictor of elbow, wrist, and ankle contractures but cannot be used to accurately predict contractures in these joints.

Patients with frog-leg squatting have restricted internal rotation and adduction of the affected hips during sitting or squatting. In the surgical literature, the cause generally has been presumed to arise from and be pathognomonic for gluteal muscle contracture. However, we have encountered patients with frog-leg squatting but without gluteal muscle contracture. We therefore raised the following questions: What are the imaging features of patients with frog-leg squatting? Do conditions other than gluteal muscle contracture manifest frog-leg squatting? We retrospectively reviewed the MR images of 67 patients presenting with frog-leg squatting from April 1998 to July 2010. There were four females and 63 males; their mean age was 22.2 years (range, 4-50 years). During MRI readout, we observed aberrant axes of some femoral necks and obtained additional CT to measure femoral torsion angles in 59 of the 67 patients. MR images of 27 (40%) patients had signs of gluteal muscle contracture. Twenty-two (33%) patients (40 femora) had aberrant femoral torsion, including diminished anteversion (range, 6°-0°; average, 3.9°) in 11 femora of eight patients and femoral retroversion (range, muscle contracture or aberrant femoral torsion. The observation of aberrant femoral torsion was not anticipated before imaging studies. In addition to gluteal muscle contracture, aberrant femoral torsion can be a cause of frog-leg squatting. Level II, diagnostic study. See the guidelines for Authors for a complete description of levels of evidence.

The transparency criteria of the German statutory health insurance on joint contracture prevention have led to controversies about the appropriate assessment, prevention and treatment as well as to various actions in nursing practice. However, appropriate nursing assessments and proven treatment options are lacking so far. It is unclear whether textbooks on nursing reflect these uncertainties. Search for textbooks on nursing through internet-based search engines and publisher registers, data extraction by one investigator and control by a second. A total of 35 textbooks with contributions on joint contractures were identified of which 25 included a definition, causes/risk factors are presented in 32 textbooks and assessments are presented in 5 books. Most often positioning into a physiological or functional neutral position and passive moving of limbs are recommended as passive prophylaxis. Recommended therapeutic and preventive options do not differ. None of the textbooks reflect that there is a lack of scientific knowledge on the subject. Textbooks on nursing do not deal with complete and scientific sound information on joint contractures.

Gluteal muscle contracture (GMC), a debilitating disease, exists all over the globe but it is much more prevalent in China. Patients typically present with abduction and external rotation of the hip and are unable to bring both the knees together while squatting. Multiple etiologies have been postulated, the commonest being repeated intramuscular injection into the buttocks. The disease is diagnosed primarily by clinical features but radiological features are necessary for the exclusion of other pathological conditions. Non-operative treatment with physiotherapy can be tried before surgery is considered but it usually fails. Different surgical techniques have been described and claimed to have a better outcome of one over another but controversy still exists. Based on published literatures, the clinical outcome is exceptionally good in all established methods of surgery. However, endoscopic surgery is superior to conventional open surgery in terms of cosmetic outcome with fewer complications. Nevertheless, its use has been limited by lack of adequate knowledge, instrumentations, and some inherent limitations. Above all, post-operative rehabilitation plays a key role in better outcome, which however should be started gradually. PMID:28059055
Full Text Available 【Abstract】Objective: To discuss the method of functional reconstruction of ischemic contracture in the lower limb and propose a classification protocol for ischemic contracture in the lower limb based on its severity and prognosis. Methods: A total of 42 patients with ischemic contracture in the lower limb were included in this study. According to different types of disturbance and degrees of severity, surgical reconstructions consisting of nerve decompression, tendon lengthening or transfer, intrinsic foot muscle release and sural-tibial nerve anastomosis were performed in every patient. Results: Postoperatively, all patients were able to walk on flat ground. Drop foot was corrected in 10 patients, and 5 patients still felt some difficulty during stair activity. Split Achilles tendon transfer to flexor hallucis longus tendon was performed in 12 patients, and their walking stability was improved. Seven patients accepted ipsilateral suraltibial nerve anastomosis, and sensitivity recovery reached to S2 in 2 patients and S3 in 5 patients. Conclusions: Ischemic contracture in the lower limb is a devastating complication after lower limb trauma. The prevention of contracture is much more important than the treatment of an established contracture. Split Achilles tendon transfer to flexor hallucis longus tendon and sural-tibial nerve anastomosis, which was initially implemented by us, could improve the functional recovery of ischemic contracture in lower limbs, and thus provides a new alternative for functional reconstruction of ischemic contracture in the lower limb. Key words: Ischemic contracture; Classification; Recovery of function

Adoption rates are increasing in the United States and other developed countries. A large proportion of adopted children have been found to have unsuspected medical diagnoses, including orthopedic problems. One condition, termed injection-induced gluteus maximus contracture, has been previously described in several case series and can be difficult to diagnose if unfamiliar with this condition. By reviewing the etiology and pathoanatomy of this problem, as well as the typical examination findings, including the near-pathognomonic-positive "reverse Ober test," treating providers will be better prepared to recognize and properly treat this condition. This is a retrospective review of 4 patients treated at our institution for injection-induced gluteus maximus contracture. Patient history, physical examination findings, and treatment outcomes were recorded. All had undergone surgical treatment through a longitudinal incision along the posterior margin of the iliotibial band, with division of thickened, contracted gluteus tissue down to the ischial tuberosity. All 4 of the patients were adopted from orphanages in developing countries. Chief complaints of the patients varied, but physical examination findings were very consistent. Three of the 4 patients had undergone rotational osteotomies for presumed femoral retroversion before their diagnosis and treatment for injection-induced gluteus maximus contracture. All patients had concave, atrophic buttock contours and numerous punctate buttock scars. All walked with an out-toed gait and had marked apparent femoral retroversion. Each patient was found to have full hip adduction when the hip was extended but a hip abduction contracture when the hip was flexed. This finding of increasing abduction as an extended/adducted hip is flexed to 90 degrees is described as a positive "reverse Ober test." After surgical treatment, all hips could adduct to neutral from full extension to full flexion. Although common in some countries

Gluteal muscle contracture (GMC), presented with hip abduction and external rotation when crouching, is common in several ethnicities, particularly in Chinese. It remains unclear that the reasons why these children are weak and have no choice to accept repeated intramuscular injection. Here, we found some unique cases which may be useful to explain this question. We describe a series of special GMC patients, who are accompanied with congenital heart disease (CHD). These cases were first observed in preoperative examinations of a patient with atrial septal defect (ASD), which was proved by chest X-ray and cardiac ultrasound. From then on, we gradually identified additional 3 GMC patients with CHD. The original patient with ASD was sent to cardiosurgery department to repair atrial septal first and received arthroscopic surgery later. While the other 3 were cured postoperative of ventricular septal defect (VSD), tetralogy of fallot (TOF), patent ductus arteriosus (PDA), respectively, and had surgery directly. The study gives us 3 proposals: (1) as to CHD children, it is essential to decrease the use of intramuscular injection, (2) paying more attention to cardiac examination especially cardiac ultrasound in perioperative period, and (3) taking 3D-CT to reconstruct gluteal muscles for observing contracture bands clearly in preoperation. However, more larger series of patients are called for to confirm these findings.

Objective Contractures are a major clinical issue for patients with muscular dystrophies. However, it is unknown whether contractures are present in the widely used mdx mouse model of Duchenne muscular dystrophy. Therefore, the objectives of this study were to develop methods to measure muscle contractures in mice, to determine whether plantarflexion contractures are present in mdx mice, and to analyze the composition of the major muscles involved. Design Hindlimbs of eight wild type and six mdx mice were assessed every 2 wks during the course of a 12-wk study. Assessments included range of motion and in vivo torques about the ankle. At the end of the study, mice were euthanized, and muscles were analyzed for composition. Results The mdx mice had ~10 degrees less dorsiflexion, increased passive torque moving the ankle into dorsiflexion, and an increased passive-to-active torque ratio relative to wild type mice. Gastrocnemius muscle composition alterations included increased wet mass, decreased protein content, and increased collagen. Conclusions The results indicate that mdx mice have plantarflexion contractures similar to those seen in children with Duchenne muscular dystrophy. In future studies, these measures can be used to assess strategies to slow the progression of contractures that occur with muscular dystrophies. PMID:21403594

To evaluate the use of ultrasonography (US) in the diagnosis of gluteal muscle contracture (GMC) by analysis of its imaging characteristics. Thirty-nine patients suspected of having GMC due to abnormal gait underwent pre-operative US. The diagnosis of GMC was confirmed by surgery in 27 patients. Six patients were diagnosed with congenital hip dysplasia, and the remaining six patients were diagnosed with sciatic nerve damage, post-poliomyelitis sequelae, and myasthenia gravis. For the patients with GMC, US showed muscle thinning and hyperechoic strips (specific for muscular contracture) in the muscles involved. In three patients with GMC, the strips were integrated into muscle bundles, demonstrating both strong and weak sonographic echoes. The sensitivity and specificity of the diagnosis of GMC using the presence of strips were 88.9% and 83.3%, respectively, and using muscle thinning, the sensitivity and specificity were 92.6% and 50%, respectively. The contracture strips, as measured by US, were significantly smaller than the actual measurements at the time of surgery, but there was a significant correlation between the two measurements (r = 0.814, P muscle (91.8%), and the lowest rate was found in the piriformis muscle (52.9%). Ultrasonography is a valuable tool for the diagnosis of GMC, especially for the detection of specific contracture strips in involved muscles. Its role in the pre-operative diagnosis of GMC also provides surgical planning that can guide subsequent treatment.

We hypothesized specific growth factors are increased in the elbow capsules of patients with post traumatic elbow contractures. A model of surgically induced joint contracture in rabbit knees was developed to study the growth factor expression in joint contractures. This study demonstrates this model mimics the human condition and analyzes how the growth factor levels decrease with time in rabbit knees with contractures. Reverse transcription polymerase chain reaction was used to measure mRNA...
Full Text Available The mortality and morbidity from burns have diminished tremendously over the last six to seven decades. However, these do not truly reflect whether the victim could go back to society as a useful person or not and lead a normal life because of the inevitable post-burn scars, contractures and other deformities which collectively have aesthetic and functional considerations. This article gives an overview of the post-burn scars and scar contractures, especially their prevention, minimisation and principles of management.

Purpose: In early stage Dupuytren's contracture radiotherapy was applied to prevent disease progression. Long-term results and late toxicity of this treatment were evaluated in a retrospective analysis. Patients and Methods: Between 1982 and 1994, 99 patients (176 hands) received orthovoltage radiotherapy, which consisted of two courses with 5 x 3 Gy (total dose: 30 Gy, daily fractionated; 120 kV, 4 mm Al), separated by a 6 to 8-week pause. The Dupuytren's contracture was staged according to the classification of Tubiana et al. The long-term outcome was analyzed at last follow-up between July and November 1999. The median follow-up was 10 years (range 7-18 years). Late toxicity was assessed using the LENT-SOMA criteria. Results: In Stage N 84% and Stage N/I 67% of cases remained stable. 65% of the cases in Stage I and 83% in Stage II showed progressive nodules and cords. In case of progression we saw no complications after a second radiotherapy or salvage operation. Conclusion: Radiotherapy effectively prevents disease progression for early stage Dupuytren's contracture (Stage N, N/I). Moreover, in case of disease progression despite radiotherapy salvage surgery is still feasible. (orig.) [de

Objective: To investigate the CT manifestations of gluteal muscle contracture (GMC) in children. Methods: Sixty-one cases of GMC diagnosed by CT and proved by surgery and pathology were studied with 20 cases of non-GMC as the control group. Results: 57 cases (93.4%) were bilateral contracture and 4 cases (6.6%) were unilateral contracture in 61 cases of GMC; The main CT manifestations were as follows: (1) gluteal muscle volume shrunk. There were 118 (100.0%) sides of gluteus maximus contracture , 16 ( 13.6 %) sides of gluteus medius contracture , 12 ( 10.2 %) sides of piriformis contracture, 4 (3.4%) sides of gluteus minimus contracture, 4 (3.4%) sides of capsula articularis contracture; (2) calcification and necrosis in injection zones. There were 95 (80.5%) sides of gluteal calcification and 24 (20.3%) sides of gluteal necrosis; (3) stripe crispation fascia. There were 81 stripes crispation fascia located outboard laterals of gluteus maximus, 36 located inboard laterals of the latter; (4) gluteal muscle clearance widened. There were 38 (32.2%) sides of light degree gluteal muscle contracture, 53 (44.9%) sides of middle degree, and 27 (22.9%) sides of heavy degree. Conclusion: CT can accurately diagnose GMC and it plays an important role in the evaluation of pathological extent and degree of GMC

Full Text Available Background. The considerable incidence of kyphosis in patients with cerebral palsy (CP causes back pain and aggravates movement disorders. However, few studies have investigated the pathogenesis of this condition. Aim. To identify the relationship between patient motor abilities, the severity of flexion contractures of the knee and hip joints and spinal sagittal profile changes, and the impact on the latter by surgical correction of flexion contracture of the knee joint. Material and methods. The study cohort included 17 pediatric CP patients (11 boys and 6 girls with a mean age of 13.1 ± 1.3 (range, 10–16 years and level 2–4 spastic diplegia according to the Gross Motor Function Classification System. The relationship between radiological indicators of the spine sagittal profile and motor abilities of children, as well as the severity of flexion contractures at the hip and knee, and the degree of insufficiency of the active extension of the knee were investigated. Of these 17 patients, 12 underwent surgery to correct flexion contracture of the knee, which involved lengthening of leg flexors, to analyze the impact of contracture on the sagittal profile of the spine. The following radiological indicators were assessed: angle of thoracic kyphosis (CC, lordosis angle (UL of the lumbar spine, and sacral inclination angle (SS. The study included patients with a CC of at least 30°. Results. Results of an X-ray study showed that the severity of kyphosis was 50.7° ± 2.1°, lordosis was 30.3° ± 4.3°, and SS was 30.5° ± 3.3°. There was a significant association between kyphosis and flexion contracture of the knee joint, as well as between lordosis and insufficient active extension of the knee joint. After elimination of the flexion contracture of the knee, the degree of severity of the CC (thoracic kyphosis was unchanged, while UL (lordosis angle and SS (sacral inclination angle increased by approximately 10°. Conclusion. The severity of

Deformities of the hands are a fairly common sequel of burn especially in the developing world. This is because of high incidence of burns, limited access to standard treatment and rehabilitation. The best outcome of a burnt hand is when deformities are prevented from developing. A good functional result is possible when due consideration is paid to hands during resuscitation, excisional surgery, reconstructive surgery and physiotherapy. The post-burns deformities of hand develop due direct thermal damage or secondary to intrinsic minus position due to oedema or vascular insufficiency. During the acute phase the concerns are, maintenance circulation minimize oedema prevent unphysiological positioning and wound closure with autogenous tissue as soon as possible. The rehabilitation program during the acute phase starts from day one and goes on till the hand has healed and has regained full range of motion. Full blown hand contractures are challenging to correct and become more difficult as time passes. Long-standing cases often land up with attenuation of extensor apparatus leading to swan neck and boutonniere deformity, muscle shortening and bony ankylosis. The major and most common pitfall after contracture release is relapse. The treatment protocol of contracture is solely directed towards countering this tendency. This article aims to guide a surgeon in obtaining optimal hand function and avoid pit falls at different stages of management of hand burns. The reasons of an unfavourable outcome of a burnt hand are possible lack of optimal care in the acute phase, while planning and performing reconstructive procedure and during aftercare and rehabilitation.

We investigated the contribution of muscle fibrosis to elbow flexion contractures in a murine model of neonatal brachial plexus injury (NBPI). Four weeks after NBPI, biceps and brachialis fibrosis were assessed histologically and compared with the timing of contracture development and the relative contribution of each muscle to contractures. Modulus of elasticity and hydroxyproline (collagen) content were measured and correlated with contracture severity. The effect of halofuginone antifibrotic therapy on fibrosis and contractures was investigated. Elbow contractures preceded muscle fibrosis development. The brachialis was less fibrotic than the biceps, yet contributed more to contractures. Modulus and hydroxyproline content increased in both elbow flexors, but neither correlated with contracture severity. Halofuginone reduced biceps fibrosis but did not reduce contracture severity. Contractures after NBPI cannot be explained solely by muscle fibrosis, arguing for investigation of alternate pathophysiologic targets for contracture prevention and treatment.

To investigate clinical efficacy and significance of gluteal muscle contracture release for the treatment of gluteal muscle contracture induced knee osteoarthritis. From January 2008 to June 2010,52 patients with gluteal muscle contracture induced knee osteoarthritis were reviewed. Among the patients,15 patients were male and 37 patients were female, ranging in age from 15 to 45 years, with an average of 35 years. Eighteen patients had left knee osteoarthritis, 30 patients had right osteoarthritis, and 4 patients had double knee osteoarthritis. All the patients were treated with gluteal muscle contracture release. Lysholm knee score was used to evaluate therapeutic effects before and after operation. All the patients were followed up,and the duration ranged from 12 to 37 years,with a mean of 15 months. The Lysholm knee score improved from preoperative (68.12 +/- 0.78) points to postoperative (91.23 +/- 0.47) points at the last follow-up, the difference had statistical difference (t=31.269, Pmuscle contracture release is effective to relieve symptoms of gluteal muscles contracture and knee osteoarthritis. The patients with gluteal muscle contracture should be treated early so as to prevent effects of gluteal muscle contracture on knee joint, slow down degeneration of knee joint at early stage, and prevent occurrence of knee osteoarthritis.

Sonoelastography plays today a major role in musculoskeletal disease, showing minor muscle injuries not well appreciable in conventional B-mode ultrasonography and integrating it in major muscle injuries diagnosis. The aim of this study was to demonstrate the ability of elastosonography in the diagnosis of muscular contracture in football players presenting negative basic echography. We examined twenty-two football players using basic echography and elastosonography approximately 24-48 hours after the traumatic event and we subsequently re-evaluated them after two weeks. Conventional echography showed, in the early stage, no muscle injuries; in twenty-two out of twenty-two patients, sonoelastography had instead underlined a heterogeneous colorimetric map, related to decreased elasticity in the area of the muscle contracture. An evaluation effected 1-2 weeks later showed a clear improvement of the sonoelastographic appearance. This information will be useful for prognostication, post-traumatic monitoring and to detect subclinical changes in MIs even before there are changes on the routine B-mode ultrasound.

A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

The aim of the present study was to evaluate the association of contractures with an increase or reduction of non-spastic muscle overactivity due to severe cerebral damage. Forty-five patients with tetraparesis after severe cerebral damage were investigated. Three groups were defined based on the presence of spasticity (revealed as resistance to passive stretch (= hypertonia)), and the presence of contracture of the relevant knee joint: Group(s) (17 patients with hypertonia without contracture), Group(s+c) (20 patients with hypertonia and contracture), and Group(c) (eight patients without hypertonia and with contracture). In all groups spontaneous involuntary muscle activity was assessed continuously over a 12-hour period through isometric measurement of knee joint flexion torque. A mathematical algorithm differentiated an hourly muscle activity spectrum (PI(h)). The frequency of peaks (peaks(h)) from the activity spectrum was determined. We revealed that Group(s) had higher PI(h) and more frequent peaks(h) compared with Group(s+c) and Group(c) (p0.05). The presence of contractures was associated with lower involuntary muscle overactivity in terms of lower PI(h) and less frequent peaks(h), indicating that contractures may be associated with reduced non-spastic positive features of the upper motor neurone syndrome in patients with severe brain damage.

The chronically dislocated paralytic hip causes postural difficulties, nursing and hygiene problems, and pain. Therapeutic options are limited. This study reviews the results of resection arthroplasty on 18 hips of 15 such patients. This procedure has many complications, including hip ankylosis, heterotopic ossification, abduction contracture and bony overgrowth. Despite this, all of the nursing goals were achieved and most patients had relief of pain. The operation is most successful in the skeletally mature patients, and it relies on soft-tissue interposition between the bony fragments and postoperative positioning to ensure optimum posture.

Full Text Available Results of surgical treatment of 21 patients with posttraumatic ischemic contractures of the first finger of a hand were analyzed. The working classification in which there are three degrees of a contracture depending on size of deficiency of a dermal cord of the first interdigital interval was offered. Advanced tactics of surgical treatment of such pathology was developed. Thus, during the first stage we carried out abduction of the first finger by the elimination of cicatrical, muscle and arthrogenic contracture components. At the second stage of treatment, if it was necessary, active opposition of the first finger was restored.

To report diagnosis and treatment of bilateral iliopsoas muscle contracture in a dog with spinous process impingement. Case report. German Shepherd dog. A dog with chronic progressive lameness, flexion contracture of the coxofemoral joints, severe pain, and decreased femoral reflexes had severe spondylosis bridging the vertebral bodies from L1 to L4 and enlarged dorsal spinous processes from T8 to L6 with impingement and bony proliferation. Ultrasonographic and magnetic resonance imaging (MRI) findings were consistent with fibrosis, mineralization, and atrophy of the iliopsoas muscles bilaterally which was treated by staged tenectomy of the insertions of the iliopsoas muscles. Because of severe perivascular fibrosis, the femoral vessels required ligation. Bilateral iliopsoas muscle tenectomy improved gait and provided pain relief. Histologic findings were consistent with fibrotic myopathy. Slow progression of severe clinical signs observed bilaterally in this dog differs from previous reports of iliopsoas myopathy. Findings were similar to the fibrotic myopathy of the gracilis or semitendinosus muscles described in dogs. Iliopsoas muscle abnormalities should be considered in dogs with limited hip extension and pain. MRI is useful for diagnosing muscle fibrosis. Iliopsoas tenectomy may improve clinical function in dogs with fibrotic myopathy.

When deprived of calcium the slow striated muscle fibers of the frog develop reversible contractures in either hypertonic or isotonic solutions. While calcium deprivation continues because of a flowing calcium-free solution the muscles relax slowly and completely. Restoration of calcium during contracture relaxes the muscle promptly to initial tension. When relaxed during calcium lack the return of calcium does not change tension and the muscle stays relaxed. When contractures are induced by solutions containing small amounts of calcium relaxation does not occur or requires several hours. The rate of tension development depends upon the rate at which calcium moves outward since the contractures develop slower in low concentrations of calcium and are absent or greatly slowed in a stagnant calcium-free solution. Withdrawal of calcium prevents the contractile responses to ACh, KCl, or electrical stimulation through the nerve. Muscles return to their original excitability after calcium is restored. Origin of the contractures is unrelated to nerve activity since they are maximal during transmission failure from calcium lack, occur in denervated muscles, and are not blocked by high concentrations of d-tubocurarine, procaine, or atropine. The experiments also indicate that the contractures do not originate from repetitive activity of muscle membranes. The findings are most simply explained by relating the outward movement of calcium as a link for initiating contraction in slow type striated muscle. PMID:14065284

The authors report the case of a 65-year-old, right-hand-dominant man who had severe Dupuytren's disease with multiple cords and flexion contractures of the metacarpophalangeal and proximal interphalangeal joints of both hands and underwent repeated collagenase injections for treatment. Collagenase has been shown to be safe and effective in the treatment of Dupuytren's contractures when administered as a single dose, but the results of multiple injections over a prolonged period are unknown. Antibodies to collagenase develop in all patients after several treatments, raising concerns about safety and efficacy as a result of sensitization from repeated exposures. The antibodies generated as a result of repeated exposure to collagenase could theoretically render it less effective with time and could also lead to immune reactions as severe as anaphylaxis. The authors present the case of a single patient who experienced continued correction of his contractures with only minor and self-limited adverse reactions after administration of 12 collagenase doses through 15 injections during a 4-year period. Over time, the injections continued to be effective at correcting metacarpophalangeal joint contractures, but less effective at correcting proximal interphalangeal joint contractures. The patient did eventually require a fasciectomy, but the safety and modest success of the repeated collagenase injections shows promise for a less invasive treatment with a better risk profile than open fasciectomy. Although further studies are needed, repeated administration of collagenase appears to be safe and modestly effective for severe Dupuytren's contractures, although a fasciectomy may ultimately be required in the most severe cases.

To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the clinical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main clinical manifestations included lameness and abnormal gait. The medical examination showed pelvic oblique and relative inequality of lower limbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic oblique. The CT scans showed no abnormal finding except pelvic oblique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabilitation exercise. All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic oblique, and 2 patients had obvious pelvic oblique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Unilateral gluteal muscle contracture leads to pelvic oblique and inequality of lower limbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and

Dupuytren's disease is a benign fibroproliferative disorder that causes the fingers to be drawn into the palm via formation of new tissue under the glabrous skin of the hand. This disorder causes functional limitations, but it can be treated through a variety of surgical techniques. As a chronic condition, it tends to recur. To assess the benefits and harms of different surgical procedures for treatment of Dupuytren's contracture of the index, middle, ring and little fingers. We initially searched the following databases on 17 September 2012, then re-searched them on 10 March 2014 and on 20 May 2015: the Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane Library, the British Nursing Index and Archive (BNI), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, the Latin American Caribbean Health Sciences Literature (LILACS), Ovid MEDLINE, Ovid MEDLINE-In-Process and Other Non-Indexed Citations, ProQuest (ABI/INFORM Global and Dissertations & Theses), the Institute for Scientific Information (ISI) Web of Science and clinicaltrials.gov. We reviewed the reference lists of short-listed articles to identify additional suitable studies. We included randomised clinical trials and controlled clinical trials in which groups received surgical intervention for Dupuytren's disease of the index, middle, ring or little finger versus control, or versus another intervention (surgical or otherwise). We excluded the thumb, as cords form on the radial aspect of the thumb and thus are not readily accessible in terms of angular deformity. Furthermore, thumb disease is rare. A minimum of two review authors independently reviewed search results to select studies for inclusion by using pre-specified criteria, assessed risk of bias of included studies and extracted data from included studies.We grouped outcomes into the following categories: (1) hand function, (2) other patient-reported outcomes (e.g. satisfaction, pain), (3) early objective

Full Text Available Background. As one of the most common musculoskeletal complications following trauma, elbow contracture is a frequent source of disabled daily activities. Conventional interventions are inadequate to provide favorable outcome. The static progressive orthoses are getting popular in the treatment of this problem. Objective. The purpose of this review was to assess the effectiveness of static progressive orthoses for elbow contracture. Methods. Literatures when written in English published during 1 January 1997 and 31 January 2017 were searched in the following databases: Web of Science, Cochrane Library, PubMed, and EBSCOhost. Articles are quality-assessed by two assessors, each article was summarized in evidence tables, and a narrative synthesis was also performed. Results. Ten clinical trials were included. The study design and outcome measures used varied. Significant immediate improvement in the range of motion was reported by all studies, and those effects were still significant at follow-up. No significant difference was shown between static progressive and dynamic orthoses for elbow contracture in one randomized control trial. Conclusions. Current low-quality evidence suggested that static progressive orthoses provided assistance for elbow contracture through improving range of motion. Further research is recommended using high-quality randomized controlled trials.

A method by which bilateral hip arthrography was performed under general anaesthesia in 130 infants and children 1 month to 7 years of age is described. Significant contractures of the adductor muscles had been corrected before the examination. Most of the children were girls with unilateral congenital idiopathic hip instability detected before the age of one year. From films exposed in standardized projections valuable information was obtained about the configuration of the joint cavity and the size and shape of the femoral head. Criteria for normal appearance in infants of ages 2 to 12 months are presented. More reliable details on the relation between the articular surfaces, the radiographic anatomy of the acetabulum and the distribution of the contrast medium were yielded by stereoradiography. Closed reduction was usually accomplished successfully during the arthrography, which made beginning of definitive treatment under the same anaesthesia possible. (Auth.)
Full Text Available Background: Children with myelomeningocele (MMC develop a wide variety of hip deformities such as muscle imbalance, contracture, subluxation, and dislocation. Various methods and indications have been introduced for treatment of muscle imbalances and other hip problems in patients with MMC but there is no study or meta-analysis to compare the results and complications. This review aims to find the most acceptable approach to hip problems in patients with MMC. Methods: MEDLINE was searched up to April 2015. All study designs that reported on the outcomes of hip problems in MMC were included. From 270 screened citations, 55 were strictly focused on hip problem in MMC were selected and reviewed. Results: Complex osseous and soft tissue reconstructive procedures to correct hip dysplasia and muscle balancing around the hip are rarely indicated for MMC patients without good quadriceps power. Conclusion: Over the years a consensus on the best algorithm for treatment of hip dislocation in myelomeningocele has been missing, however, muscular balancing with/out osseous procedure seems a reasonable approach especially in unilateral mid-lumbar MMC.

In newborns, US has an established role in the detection and management of developmental dysplasia of the hip. Later in childhood, when the limping child is a major diagnostic dilemma, US is extremely helpful in the identification of the varied disease processes underlying this condition, as transient synovitis, septic arthritis, Perthes disease and slipped femoral capital epiphysis. In adolescent practicing sporting activities, US is an excellent means to identify apophyseal injures about the pelvic ring, especially when avulsions are undisplaced and difficult-to-see radiographically. Later on, in the adulthood, US is an effective modality to diagnose tendon and muscle injuries about the hip and pelvis, identify effusion or synovitis within the hip joint or its adjacent bursae and guide the treatment of these findings. The aim of this article is to provide a comprehensive review of the most common pathologic conditions about the hip, in which the contribution of US is relevant for the diagnostic work-up.

Full Text Available Hip arthroscopy is a safe method for treating a variety of pathological conditions that were unknown until a decade ago. Femoroacetabular impingement is the commonest of these pathological conditions and the one with the best results when treated early on. The instruments and surgical technique for hip arthroscopy continue to evolve. New indications for hip arthroscopy has been studied as the ligamentum teres injuries, capsular repair in instabilities, dissection of the sciatic nerve and repair of gluteal muscles tears (injuries to the hip rotator cuff, although still with debatable reproducibility. The complication rate is low, and ever-better results with fewer complications should be expected with the progression of the learning curve.
Full Text Available Hand burn scar contractures affect patients in aesthetic and functional aspects. After releasing these scars, the defects should be repaired. The reconstruction methods include primary suturation, Z plasty, skin grafting, local or free flaps, etc. All methods have their own advantages and disadvantages. One of the most useful flaps is the reverse ulnar perforator flap. We performed a two-staged procedure for repairing a post-burn contracture release defect in a 40-year-old male. In the first stage we applied reverse ulnar perforator flap for the hand defect, and ulnar artery and vein repair in the second stage. In conclusion, this two-staged procedure is a non-primary but useful option for hand and finger defects and prevents major vascular structure damage of the forearm.

Clinical summary: A 13-year-old, spayed Devon Rex with unilateral digital flexor musculotendinous contracture of the forelimb was treated by surgical tenotomy. The condition improved transiently, but recurred rapidly and became bilateral. Histopathologic analysis of necropsy tissues resulted in a morphologic diagnosis of fibromyositis of the antebrachial muscles causing contracture and flexural deformity of the carpi and phalanges of both thoracic limbs. A search for similar cases yielded the clinical notes of a second cat, a 10-year-old, spayed Devon Rex, also with bilateral disease. This second case responded well to surgical tenotomy but tissue biopsies were not obtained to permit microscopic assessment of the underlying pathologic process. Relevance and novel information: Acquired and permanent contracture of the digital flexor muscles and/or tendons of the forelimbs is a rare and poorly described condition of cats. The very limited number of documented cases describing disease affecting one or more digits (but not the carpus) infers a causal link with onychectomy, but reported histopathologic changes have been limited to the tendons. The two cases described in this report suffered contracture of the carpus and all digits bilaterally, one without previous onychectomy and the other 9 years after onychectomy. There were novel histopathologic findings in the muscles of the one case for which biopsy material was available. Information gained from these two cases provides a new perspective for the investigation and treatment of future cases. Specifically, consideration should be given to an underlying immune-mediated myopathic process and a possible genetic predisposition in the Devon Rex breed. Currently, the poorly understood etiopathogenesis hinders our ability to definitively recommend treatment options, which might include corticosteroids and other forms of immunosuppressive therapy.

Muscle contractures are common in patients with central motor lesions, but the mechanisms responsible for the development of contractures are still unclear. Increased or decreased neural activation, protracted placement of a joint with the muscle in a short position and muscle atrophy have been...... suggested to be involved, but none of these mechanisms are sufficient to explain the development of muscle contractures alone. Here we propose that changes in tissue homeostasis in the neuro-muscular-tendon-connective tissue complex is at the heart of the development of contractures, and that an integrated...... physiological understanding of the interaction between neural, mechanical and metabolic factors, as well as genetic and epigenetic factors, is necessary in order to unravel the mechanisms that result in muscle contractures. We hope thereby to contribute to a reconsideration of how and why muscle contractures...

To give information about intracellular Ca^ translocation during and after K-contractures in vertebrate skeletal muscle fibers, we examined recovery of action potentials and twitches after interruption and spontaneous relaxation of K-contractures at low temperature (3℃) that greatly reduced the rate of Ca^ reuptake by the sarcoplasmic reticulum. On membrane repolarization interrupting K-contractures, the amplitude of both action potentials and twitches recovered quickly, while the falling pha...
Full Text Available Perineal burn contracture is a rare burn sequel. We conducted a retrospective analysis of cases with perineal burn contractures managed in a tertiary care centre of a Himalayan state. We found that all cases sustained burn injury from burning firewood and the time of presentation was two to six years after the burn injury. We analyzed our treatment method and have classified these contractures into two types.

To examine the prevalence of joint contractures in the upper limb and association with voluntary strength, innervation status, functional status, and demographics in a convenience sample of individuals with cervical spinal cord injury to inform future prospective studies. Cross-sectional convenience sampled pilot study. Department of Veterans Affairs Research Laboratory. Thirty-eight participants with cervical level spinal cord injury. Not applicable. Contractures were measured with goniometric passive range of motion. Every joint in the upper extremity was evaluated bilaterally. Muscle strength was measured with manual muscle testing. Innervation status was determined clinically with surface electrical stimulation. Functional independence was measured with the Spinal Cord Independence Measure III (SCIM-III). Every participant tested had multiple joints with contractures and, on average, participants were unable to achieve the normative values of passive movement in 52% of the joints tested. Contractures were most common in the shoulder and hand. There was a weak negative relationship between percentage of contractures and time post-injury and a moderate positive relationship between percentage of contractures and age. There was a strong negative correlation between SCIM-III score and percentage of contractures. Joint contractures were noted in over half of the joints tested. These joint contractures were associated with decreased functional ability as measured by the SCIM-III. This highlights the need the need for detailed evaluation of the arm and hand early after injury as well as continued monitoring of joint characteristics throughout the life course of the individual with tetraplegia.

Contractures, a common complication following immobility, lead to restricted joint range of motion. Passive movements (PMs) are widely used for the treatment and prevention of contractures; however, it is not clear whether they are effective. The aim of this review was to determine the effects of PMs on persons with contractures or at risk of developing contractures. Specifically, the aim was to determine whether PMs increase joint mobility. We searched the Cochrane Injuries Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid SP), EMBASE (Ovid SP), ISI Web of Science (SCI-EXPANDED; SSCI; CPCI-S; CPCI-SSH), PEDro and PsycINFO (Ovid SP). The search was run on 21 November 2013. Randomised controlled trials of PMs administered for the treatment or prevention of contractures were included. Studies were included if they compared the effectiveness of PMs versus no intervention, sham intervention or placebo in people with or at risk of contracture. Studies that involved other co-interventions were included, provided the co-interventions were administered in the same way to all groups. Interventions administered through mechanical devices and interventions that involved sustained stretch were excluded. Three independent review authors screened studies for inclusion. Two review authors then extracted data and assessed risk of bias. Primary outcomes were joint mobility and occurrence of adverse events such as joint subluxations or dislocations, heterotopic ossification, autonomic dysreflexia and fractures or muscle tears. Secondary outcomes were quality of life, pain, spasticity, activity limitations and participation restrictions. We used standard methodological procedures as advocated by the Cochrane Handbook for Systematic Reviews of Interventions. Two identified studies randomly assigned a total of 122 participants with neurological conditions comparing PMs versus no PMs. Data from 121 participants were available for
Full Text Available Background. Fibromatosis represents a wide group of benign, locally proliferative disorders of fibroblasts. Dupuytren` s disease is a benign proliferative disease of palmar aponeurosis which usually affects adults between 40 and 60 years of age. Ledderhose`s disease or plantar fibromatosis is plantar equivalent of Dupuyten`s disease most often affecting middle- aged and older men, usually bilateral, represented with painless nodule in the medial division of plantar fascia. Case report. We presented a 19-year old adolescent that turned to a plastic surgeon complaining to his small finger contracture. He noticed palmar thickening with nodule over the metacarpophalangeal joint of small finger of his right hand when he was 16 years old. A year later a finger started to band. During physical checkup we noticed plantar nodule that also had his father and grandmother. Magnetic resonance and tumor biopsy confirmed a suspicion on plantar fibromatosis - Ledderhose`s disease. Clinical exam of the hand clearly led to a conclusion that the patient had Dupuytren`s contracture with pretendinous cord over the small finger flexor tendons and lack of extension of proximal interphalangeal (PIP joint. On the extensor side of the PIP joints there were Garrod`s nodes. The patient refused surgical treatment of plantar tumor, but agreed to surgical correction of finger contracture. Conclusion. Despite the fact that Dupuytren`s disease and plantar fibromatosis are diseases of adults, the possibility of conjoint appearance of these forms of fibromatosis in adolescent period of life should be kept in mind especially in patients with strong genetic predisposition.

Case report with review describes X-linked muscular dystrophy with contractures in 28 years old man and his cousin. The disease revealed itself in an early stage (age 5-10), the process was progressing with apparent tendons retraction and contraction, limited movement in the areas of the neck and back of spine, atrophy of shoulder and pelvic yard and back muscles. Intellect was intact. Cardyomyopathy was exhibited. CK was normal. EMG showed classic myopathic features. Muscle biopsy showed different caliber groups of muscle fibers, growth of endo-perimesial connective tissue. Clinical manifestations together with electrophysiological and histological data suggest consistency with Rotthauwe-Mortier-Bayer X-linked muscular dystrophy.

In frog ventricle, developed tension was markedly larger in response to depolarization caused by a voltage clamp step than to depolarization induced by high concentrations of potassium chloride. Measurement of extracellular potassium activity at the surface and at the depth of muscle during the development of contractures showed that the diffusion of potassium is much slower than the spread of depolarization through the cross section of muscle. These two observations suggest that competition between the depolarizing and the negative inotropic effects of an increase in the extracellular potassium ion concentration may determine the time course and magnitude of contractile tension in heart muscle.

Patients with arthrogryposis multiplex congenita have a characteristic upper extremity resting posture consisting of internal rotation of the shoulders, elbow extension, flexed wrists, thumb-in palm deformities, and variable degrees of finger contractures. Treatment of these patients is aimed at improving independence and performance of activities of daily living. Although each area needs to be assessed independently for the most appropriate surgical procedure, often multiple areas can be addressed at the same operative setting. This limits the number of anesthetic exposures and cast immobilization time. The following is a synopsis of treatment strategies presented at the second international symposium on Arthrogryposis which took place in St Petersburg in September 2014.

Canine and feline muscle contracture is reported to affect several different muscles, is associated with a number of predisposing factors, and a varying prognosis depending upon which muscle is affected. Most patients suffer some form of trauma weeks to months before the contracture is present. The clinical signs include: lameness, pain, weakness, decreased range of motion, a firmness noted throughout the entire muscle, and usually a characteristic gait. Pre-disposing factors for muscle contracture include: compartment syndrome, infection, trauma, repetitive strains, fractures, infectious diseases, immune-mediated diseases, neoplasia, and ischaemia. There does appear to be some breed and age predilection, however, the sex of the animal does not have an appreciable influence. In general, muscle contractures of the forelimb respond better to treatment and carry a better prognosis than muscle contractures of the hindlimb.

Full Text Available Abstract Background Splinting as part of the overall post-surgical management of patients after release of Dupuytren's contracture has been widely reported, though there is variation in practice and criteria for using it. The evidence on its effectiveness is sparse, of poor quality and contradictory with studies reporting negative and positive effects. Methods/Design A multi-centre, pragmatic, randomized, controlled trial is being conducted to evaluate the effect of static night splinting for six months on hand function, range of movement, patient satisfaction and recurrence at 1 year after fasciectomy or dermofasciectomy. Using a centrally administered computer randomization system consented patients will be allocated to one of two groups: i splint group who will be given a static splint at approximately 10 to 14 days after surgery to be worn for 6 months at night time only as well as hand therapy; ii non-splint group, who will receive hand therapy only. The primary outcome measure is the patient-reported Disabilities of the Arm, Hand and Shoulder Questionnaire (DASH. Secondary outcomes are total active flexion and extension of fingers, patient satisfaction and recurrence of contracture. Outcome measures will be collected prior to surgery, 3 months, 6 months and 1 year after surgery. Using the DASH as the primary outcome measure, where a difference of 15 points is considered to be a clinically important difference a total of 51 patients will be needed in each group for a power of 90%. An intention-to-treat analysis will be used. Discussion This pragmatic randomized controlled trial will provide much needed evidence on the clinical effectiveness of post-operative night splinting in patients who have undergone fasciectomy or dermofasciectomy for Dupuytren's contracture of the hand.

In human genetics and orthopedics quite different answers have been given to the question of hereditary transmission and frequency of hip dysplasia in families of children with congenital hip dislocation. We therefore have made roentgenometric measurements of 110 parents of children with congenital hip dislocation. In 25% we found abnormal flat acetabulae, whereas 12% had pathologic deep hips. This may propose a new concept of morphology of congenital hip dysplasia.

Full Text Available One of the major determinants of Dupyutren disease (DD treatment efficacy is recurrence of the contracture. Unfortunately, lack of agreement in the literature on what constitutes recurrence makes it nearly impossible to compare the multiple treatments alternatives available today. The aim of this study is to bring an unbiased pool of experts to agree upon what would be considered a recurrence of DD after treatment; and from that consensus establish a much-needed definition for DD recurrence.To reach an expert consensus on the definition of recurrence we used the Delphi method and invited 43 Dupuytren's research and treatment experts from 10 countries to participate by answering a series of questionnaire rounds. After each round the answers were analyzed and the experts received a feedback report with another questionnaire round to further hone in of the definition. We defined consensus when at least 70% of the experts agreed on a topic.Twenty-one experts agreed to participate in this study. After four consensus rounds, we agreed that DD recurrence should be defined as "more than 20 degrees of contracture recurrence in any treated joint at one year post-treatment compared to six weeks post-treatment". In addition, "recurrence should be reported individually for every treated joint" and afterwards measurements should be repeated and reported yearly.This study provides the most comprehensive to date definition of what should be considered recurrence of DD. These standardized criteria should allow us to better evaluate the many treatment alternatives.

This is a report of studies of time-dose relationships for post-irradiation leg contractures in mice. The isoeffect doses for various degrees of contracture, measured 250 days after irradiation, increased with the number of fractions, but not with the overall treatment times, throughout 30 days. The isoeffect curves relating the total doses for given levels of responses to the doses per fraction were steeper for leg contractures than for acute skin reactions. The alpha/beta ratios ranged from 1.4 to 5.0 Gy, depending on the degrees of contracture. They were less than the 7.5 to 50 Gy for acute skin reactions as determined in previous experiments using the same animals and irradiation systems. Thus, the data resembled those from other slowly-responding normal tissues such as the spinal cord, kidney and lung. The leg contracture consisted of dermatogenic, myogenic, and arthrogenic components; after the mice were sacrificed there was residual contracture following removal of the skin and muscle. Inhibition of bone growth accounted for only a small proportion of the contracture. The overall response reflected responses of several tissue types

Little is known about the relation between residual muscle strength and joint contracture formation in neuromuscular disorders. This study aimed to investigate the relation between residual muscle strength and shoulder joint contractures in children with sequelae of obstetric brachial plexus lesion (OBPL). In OBPL a shoulder joint contracture is a frequent finding. We hypothesize that residual internal and external rotator strength and their balance are related to the extent of shoulder joint contracture. Clinical assessment was performed in 34 children (mean 10.0 years) with unilateral OBPL and Narakas classes I-III. External and internal rotation strengths were measured with the shoulder in neutral position using a handheld dynamometer. Strength on the affected side was given as percentage of the normal side. Contracture was assessed by passive internal and external rotations in degrees (in 0° abduction). Mallet classification was used for active shoulder function. External and internal rotation strengths on the affected side were approximately 50% of the normal side and on average both equally affected: 56% (SD 18%) respectively 51% (SD 27%); r = 0.600, p = 0.000. Residual strengths were not related to passive internal or external rotation ( p > 0.200). Internal rotation strength ( r = - 0.425, p muscle strength influence contracture formation cannot be confirmed in this study. Our results are of interest for the understanding of contracture formation in OBPL.

Full Text Available Objective: Hand burns are common injuries. Children frequently sustain burn injuries, especially to their hands. Contractures are a common sequel of severe burns around joints. The prepuce, or foreskin, has been used as a skin graft for a number of indications. We conducted this study to evaluate the feasibility of utilising the preputial skin for the management of post-burn contractures of fingers in uncircumcised male children. Materials and Methods: Preputial skin was used for the coverage of released contractures of fingers in 12 patients aged 2-6 years. The aetiology of burns was "Kangri" burn in eight patients and scalding in four patients. Six patients had contracture in two fingers, four patients in one finger, and two patients had contractures in three fingers. Results: None of the patients had graft loss, and all the wounds healed within 2 weeks. All patients had complete release of contractures without any recurrence. Hyperpigmentation of the grafts was observed over a period of time, which was well accepted by the parents. Conclusions: Preputial skin can be used successfully for male children with mild-to-moderate contractures of 2-3 fingers for restoration of the hand function, minimal donor site morbidity.

The etiology of shoulder and elbow contractures following neonatal brachial plexus injury is incompletely understood. With use of a mouse model, the current study tests the novel hypothesis that reduced growth of denervated muscle contributes to contractures following neonatal brachial plexus injury. Unilateral brachial plexus injuries were created in neonatal mice by supraclavicular C5-C6 nerve root excision. Shoulder and elbow range of motion was measured four weeks after injury. Fibrosis, cross-sectional area, and functional length of the biceps, brachialis, and subscapularis muscles were measured over four weeks following injury. Muscle satellite cells were cultured from denervated and control biceps muscles to assess myogenic capability. In a comparison group, shoulder motion and subscapularis length were assessed following surgical excision of external rotator muscles. Shoulder internal rotation and elbow flexion contractures developed on the involved side within four weeks following brachial plexus injury. Excision of the biceps and brachialis muscles relieved the elbow flexion contractures. The biceps muscles were histologically fibrotic, whereas fatty infiltration predominated in the brachialis and rotator cuff muscles. The biceps and brachialis muscles displayed reduced cross-sectional and longitudinal growth compared with the contralateral muscles. The upper subscapularis muscle similarly displayed reduced longitudinal growth, with the subscapularis shortening correlating with internal rotation contracture. However, excision of the external rotators without brachial plexus injury caused no contractures or subscapularis shortening. Myogenically capable satellite cells were present in denervated biceps muscles despite impaired muscle growth in vivo. Injury of the upper trunk of the brachial plexus leads to impaired growth of the biceps and brachialis muscles, which are responsible for elbow flexion contractures, and impaired growth of the subscapularis

Following neonatal brachial plexus palsy, the Putti sign-obligatory tilt of the scapula with brachiothoracic adduction-suggests the presence of glenohumeral abduction contracture. In the present study, we utilized magnetic resonance imaging (MRI) to quantify this glenohumeral abduction contracture and evaluate its relationship to shoulder joint deformity, muscle atrophy, and function. We retrospectively reviewed MRIs of the thorax and shoulders obtained before and after shoulder rebalancing surgery (internal rotation contracture release and external rotation tendon transfer) for twenty-eight children with unresolved neonatal brachial plexus palsy. Two raters measured the coronal positions of the scapula, thoracic spine, and humeral shaft bilaterally on coronal images, correcting trigonometrically for scapular protraction on axial images. Supraspinatus, deltoid, and latissimus dorsi muscle atrophy was assessed, blinded to other measures. Correlations between glenohumeral abduction contracture and glenoid version, humeral head subluxation, passive external rotation, and Mallet shoulder function before and after surgery were performed. MRI measurements were highly reliable between raters. Glenohumeral abduction contractures were present in twenty-five of twenty-eight patients, averaging 33° (range, 10° to 65°). Among those patients, abductor atrophy was present in twenty-three of twenty-five, with adductor atrophy in twelve of twenty-five. Preoperatively, greater abduction contracture severity correlated with greater Mallet global abduction and hand-to-neck function. Abduction contracture severity did not correlate preoperatively with axial measurements of glenohumeral dysplasia, but greater glenoid retroversion was associated with worse abduction contractures postoperatively. Surgery improved passive external rotation, active abduction, and hand-to-neck function, but did not change the abduction contracture. A majority of patients with persistent shoulder weakness

Objective: To evaluate the MRI findings and its diagnostic value in gluteal muscle contracture (GMC). Methods: Eleven clinic or operation confirmed GMC patients were examined by plain X-ray and MRI. Conventional T 1 WI and T 2 WI MR imaging were performed and FFE-T 2 WI (fast field echo-T 2 WI) was also scanned. CT scan was conducted in 5 cases. Results: 11 GMC patients were all diagnosed by MRI. Conventional T 1 WI and T 2 WI could only show the atrophy of gluteal muscles, while FFE-T 2 WI could directly show the fibrous band of gluteal muscle and its fascia, and the fibrous band appeared as low signal intensity on FFE-T 2 WI sequence. Conclusions: MRI is the efficient modality in imaging the fibrous band for GMC patients, and FFE-T 2 WI is the most valuable sequence. MRI is very helpful in the diagnosis and treatment of GMC
Nils Silfverskiöld was an orthopaedic surgeon, Swedish aristocrat, bon vivant, Olympic gymnast, left wing intellectual and anti-Nazi who described that the force required to dorsiflex the ankle in spastic equinus contracture decreased with knee flexion in isolated gastrocnemius contracture. He advocated detaching the origins of the gastrocnemii from the femur and reattaching them to the tibia. The Silfverskiöld knee flexion test has now also been adapted to distinguish between isolated gastrocnemius contracture and combined shortening of the gastrocnemius-soleus complex in non-spastic contracture by measuring the range of ankle dorsiflexion with the knee flexed and the knee straight.

The purpose of this study is to report our experience with free functional muscle transfer procedures for the late sequelae of the rare condition of congenital Volkmann's ischaemic contracture of the forearm. Four children, with an average age of 9.5 years (range 1.5-17), were treated and were followed for a mean of 6 years (range 1-14). Two patients had dorsal forearm contractures, and two had both flexor and extensor forearm contractures. We carried out free functional muscle transfers to replace the flexor or extensor muscles. The functional result was assessed according to the classification system of Hovius and Ultee. All patients had wrist contractures and skeletal involvement with limb length discrepancy that influenced the outcome. All five transferred muscles survived and improved the function of the hand in three of the four patients. LEVEL OF EVIDENCE 4. © The Author(s) 2014.

Joint contractures alter the mechanical properties of articular and muscular structures. Reversibility of a contracture depends on the restoration of the elasticity of both structures. We determined the differential contribution of articular and muscular structures to knee flexion contractures during spontaneous recovery. Rats (250, divided into 24 groups) had one knee joint surgically fixed in flexion for six different durations, from 1 to 32 wk, creating joint contractures of various severities. After the fixation was removed, the animals were left to spontaneously recover for 1 to 48 wk. After the recovery periods, animals were killed and the knee extension was measured before and after division of the transarticular posterior muscles using a motorized arthrometer. No articular limitation had developed in contracture of recent onset (≤2 wk of fixation, P > 0.05); muscular limitations were responsible for the majority of the contracture (34 ± 8° and 38 ± 6°, respectively; both P contractures of recent onset (1 and 2 wk of fixation, respectively). Long-lasting contractures (≥4 wk of fixation) presented articular limitations, irreversible in all 12 durations of recovery compared with controls (all 12 P contractures of recent onset were primarily due to muscular structures, and they were reversible during spontaneous recovery. Long-lasting contractures were primarily due to articular structures and were irreversible. Comprehensive temporal and quantitative data on the differential reversibility of mechanically significant alterations in articular and muscular structures represent novel evidence on which to base clinical practice.

The objective of this study was to evaluate the effectiveness of serial casting of elbow flexion contractures in neonatal brachial plexus palsy. A prospective consecutive cohort study was performed with a median follow-up of 5 years. Forty-one patients with elbow flexion contractures ≥ 30° were treated with serial casting until the contracture was ≤ 10°, for a maximum of 8 weeks. Range of motion, number of recurrences and patient satisfaction were recorded and analyzed using Wilcoxon signed-rank and Cox regression tests. Passive extension increased from a median of -40° (IQR -50 to -30) to -15° (IQR -10 to -20, p casting had to be prematurely replaced by night splinting due to complaints. Serial casting improved elbow flexion contractures, although recurrences were frequent. The severity of elbow flexion contracture is a predictor of recurrence. We recommend more research on muscle degeneration and determinants involved in elbow flexion contractures to improve treatment strategies and prevent side-effects.

Full Text Available The frequency of recurrent contractures of the joints of the lower limb after their correction by means of tendon-muscle plasty remains significant. Therefore, the search for effective ways to correct contractures with the most resistant long-term result is relevant. The objective of the study is to improve treatment outcomes of equinus contracture in children with spastic paralysis. Materials and methods. We analyzed the results of correction of contractures in joints of lower limbs in 40 patients with cerebral palsy and the influence of spasticity of patognomonic muscles on them. The mean age was 6 years 7 months. In addition, for the correction of hypertonus of triceps muscle of tibia, the 330 lower limb segments were performed selective neurotomy of appropriate motor branches of the general tibial nerve. This operation in 304 cases was combined with achilloplastics or Strayer operation. Results. A mean degree of correlation between the degree of contracture in the ankle and increased tone of triceps tibia was determined (r value ranged from 0.451 to 0.487. Short-term results of the combined neuroorthopedic method for correction of contractures were good in estimating within 1 year post surgery, but a study of its short-run effect requires long-term follow-up.

Lower extremity contracture associated with stroke commonly results in a nonreducible, spastic equinovarus deformity of the foot and ankle. Rigid contracture deformity leads to gait instability, pain, bracing difficulties, and ulcerations. The classic surgical approach for stroke-related contracture of the foot and ankle has been combinations of tendon lengthening, tendon transfer, osteotomy, and joint fusion procedures. Recovery after traditional foot and ankle reconstructive surgery requires a period of non-weightbearing that is not typically practical for these patients. Little focus has been given in published studies on minimally invasive soft tissue release of contracture. We present the case of a 61-year-old female with an equinovarus foot contracture deformity secondary to stroke. The patient underwent Achilles tendon lengthening, posterior tibial tendon Z lengthening, and digital flexor tenotomy of each toe with immediate weightbearing in a walking boot, followed by transition to an ankle-foot orthosis. The surgical principles and technique tips are presented to demonstrate our minimally invasive approach to release of foot and ankle contracture secondary to stroke. The main goal of this approach is to improve foot and ankle alignment for ease of bracing, which, in turn, will improve gait, reduce the risk of falls, decrease pain, and avoid the development of pressure sores.

To investigate the prevalence of joint contracture (limited passive range of joint motion) and muscle weakness in a population with multiple sclerosis (MS). A secondary aim was to establish normative data of functional tests of mobility and balance of people with MS who are still ambulant. Cross-sectional study. People with MS living in metropolitan Sydney, Australia. 330 people with MS living in metropolitan Sydney, Australia were randomly sampled on 23 July 2009 from the MS Australia register and invited to participate. Passive range of motion of large joints of the limbs and muscle strength. Tests of walking and balance were also conducted. 156 people (109 females, 47 males; mean age 54.2 years; mean time since diagnosis 14.9 years) agreed to participate and were assessed. Fifty-six per cent (56%) of participants had contracture in at least one major joint of upper or lower limb. The most common site of contracture was the ankle (43.9%). Seventy per cent (70%) of participants had muscle weakness in one or more muscle groups. As muscle weakness, joint contractures were present at early stage of MS and the prevalence was associated with the progression of the disease. These data show that in addition to muscle weakness joint contractures are highly prevalent among people with MS, especially in the ankle joint. This implicates that prevention of contracture is crucial in providing rehabilitation to people with MS.

Muscle contractures are common in patients with central motor lesions, but the mechanisms responsible for the development of contractures are still unclear. Increased or decreased neural activation, protracted placement of a joint with the muscle in a short position and muscle atrophy have been suggested to be involved, but none of these mechanisms are sufficient to explain the development of muscle contractures alone. Here we propose that changes in tissue homeostasis in the neuromuscular-tendon-connective tissue complex is at the heart of the development of contractures, and that an integrated physiological understanding of the interaction between neural, mechanical and metabolic factors, as well as genetic and epigenetic factors, is necessary in order to unravel the mechanisms that result in muscle contractures. We hope thereby to contribute to a reconsideration of how and why muscle contractures develop in a way which will open a window towards new insight in this area in the future. © 2016 The Authors.

Gluteal muscle contracture (GMC), a debilitating disease, usually starts in early childhood after variable dose of injections around the buttock, if left untreated it worsens gradually and persists throughout the life. Because the disease mostly affects adolescents and adults, there is always an aesthetic concerns. Purposeof the study was to introduce the arthroscopic F and C method of GMC release, and to compare its clinical efficiency with conventional open surgery in terms of clinical outcome, rate of complications, patient's satisfactions, and recurrence. Between Jan 2013 and July 2015, 75 patients received an arthroscopic release with F and C release method and 71 patients received conventional open release of GMC. Primary surgeries in 16 years or older patients were included in the study. Two groups were compared clinically using Hip Outcome Scores - Activities of Daily Living Subscale (HOS-ADL), Hip Outcome Scores - Sports Subscale (HOS-Sports), Visual Analogue Scale (VAS), and Ye et al. evaluation criteria. No statistically significant differences were observed in Hip Outcome Scores - Activities of Daily Living Subscale (HOS-ADL) (P = 0.078), Hip Outcome Scores - Sports Subscale (HOS-Sports) (P = 0.340), and Visual Analogue Scale (VAS) (P = 0.524) between the two groups. 74 (98.7%) patients in the arthroscopic surgery group had good to excellent results, whereas 69 (97.1%) patients in the conventional open surgery group had good to excellent results (P = 0.727). No statistically significant difference was observed in recurrence rate (P = 0.612). Statistically significant differences were observed in incision length, use of post-operative analgesia, post-operative off-bed activity, and hospital stay. Complications were significantly higher in the conventional open surgery group (n = 21) than in the arthroscopic surgery group (n = 10) (P = 0.016). More importantly, cosmetic satisfaction was 100% in arthroscopic release group

The development of contracture related to changes of ionic environment (ionic contracture coupling) has been studied in the slowly responding fibers of frog skeletal muscle. When deprived of external ions for 30 minutes by use of solutions of sucrose, mannitol, or glucose, the slow skeletal muscle fibers, but not the fast, develop pronounced and easily reversible contractures. Partial replacement of the non-ionic substance with calcium or sodium reduces the development of the contractures but replacement by potassium does not. The concentration of calcium necessary to prevent contracture induced by a non-ionic solution is greater than that needed to maintain relaxation in ionic solutions. To suppress the non-ionic-induced contractures to the same extent as does calcium requires several fold higher concentrations of sodium. Two types of ionic contracture coupling occur in slow type striated muscle fibers: (a) a calcium deprivation type which develops maximally at full physiological concentration of external sodium, shows a flow rate dependency for the calcium-depriving fluid, and is lessened when the sodium concentration is decreased by replacement with sucrose; (b) a sodium deprivation type which occurs maximally without external sodium, is lessened by increasing the sodium concentration, and has no flow rate dependency for ion deprivation. Both types of contracture are largely prevented by the presence of sufficient calcium. There thus seem to be calcium- and sodium-linked processes at work in the ionic contracture coupling of slow striated muscle. PMID:14127603

Skeletal muscle tissue is mechanosensitive, as it is able to sense mechanical impacts and to translate these into biochemical signals making the tissue adapt. Among its mechanosensitive nature, skeletal muscle tissue is the largest metabolic organ of the human body. Disturbances in skeletal muscle mechanosensing and metabolism cause and contribute to many diseases, i.e. muscular dystrophies/myopathies, cardiovascular diseases, COPD or diabetes mellitus type 2. A less commonly focused muscle-related disorder is clinically known as muscle contractures that derive from cerebral palsy (CP) conditions in young and adults. Muscle contractures are characterized by gradually increasing passive muscle stiffness resulting in complete fixation of joints. Different mechanisms have been identified in CP-related contractures, i.e. altered calcium handling, altered metabolism or altered titin regulation. The muscle-related extracellular matrix (ECM), specifically collagens, plays a role in CP-related contractures. Herein, we focus on mechanically sensitive complexes, known as costameres (Cstms), and discuss their potential role in CP-related contractures. We extend our discussion to the ECM due to the limited knowledge of its role in CP-related contractures. The aims of this review are (1) to summarize CP-related contracture mechanisms, (2) to raise novel hypotheses on the genesis of contractures with a focus on Cstms, and (3) to stimulate novel approaches to study CP-related contractures.

The pathophysiology of elbow flexion contracture (EFC) in obstetrical brachial plexus injury (OBPI) is not established. In basic science models, neonatal denervation leads to impaired muscle growth. In clinical studies, diminished growth is correlated with extent of denervation, and improved with surgical repair. In EFC, the biceps are clinically short and round vs the contralateral size, termed the "Popeye muscle". The objective of this study was to determine if the biceps morphology (muscle belly and tendon length) in arms with EFC secondary to OBPI is different vs the contralateral. This is a retrospective matched-cohort study. Patients with unilateral EFC (>20°) secondary to OBPI were identified (median = 6.6 years, range = 4.7-16.8). A blinded radiologist used computed tomography to measure length of the biceps short head muscle belly, and tendon bilaterally using standardised anatomical landmarks. Twelve patients were analyzed. The biceps muscle belly in the injured arm was shorter in all patients vs contralateral, mean difference = 3.6 cm (80%), p muscle belly and overall length, but longer tendon vs normal. This is termed the "Popeye muscle" for its irregular morphology. Findings are consistent with impaired limb growth in denervation.

Joint contractures are a common problem for older, frail people, particularly in rehabilitation, nursing home and homecare settings. Joint contractures are underreported and sparsely empirically investigated despite their high prevalence. The objective of this study was to examine the prevalence of functional impairments, activity limitations and participation restrictions of patients with joint contractures using the International Classification of Functioning, Disability and Health (ICF) as a framework. We also examined contextual factors as potential mediators for functioning and disability. Cross-sectional study- Three acute-geriatric hospitals in and around Munich (Germany). Patients aged 65 and over with confirmed joint contractures requiring rehabilitation care. The patients were asked to answer a questionnaire that comprised 124 categories of the ICF. Patients' problems in functioning were registered separately for each category. Data were collected through face-to-face interviews with patients and health professionals and from patients' medical records. One hundred and fifty patients were eligible and agreed to participate. Mean age was 82.5 years (SD: 7.4), 64.8% of the patients were female. Problems in "muscle power functions" (95.9%) and "driving human-powered transportation" (89,6%) were those most frequently identified. 'Health services, systems and policies' (98,6%) was the most frequent environmental facilitator. Aged persons with joint contractures experience high levels of disability. Specifically, mobility, participation restrictions and interactions with the environment emerged as important issues of our study. Mobility and support by others were frequently mentioned as aspects relevant for persons with joint contractures. These aspects have to be considered when assessing the impact of joint contractures.

Contracture of the wrist and extrinsic finger flexor and pronator muscles is a common consequence of central nervous system disorders. The proximal release of the extrinsic flexor and pronator muscles was first described by Page and Scaglietti for a Volkmann contracture. The aim of the present study was to assess the amount of increase in extension and the improvements in global hand function that can be expected following this lengthening procedure in patients with central nervous system disorders. A single-center retrospective review of patients with central nervous system lesions and contractures of the wrist and extrinsic finger flexor and forearm pronator muscles, causing aesthetic, hygienic, or functional impairment, was carried out. The Page-Scaglietti technique was used for all interventions. Before the operation, motor nerve blocks were used to distinguish between spasticity and contractures with surgical intervention only for contractures. The Zancolli and House classifications were used to evaluate improvements. Data from fifty-four hands and fifty patients (thirty-five men and fifteen women) were evaluated. The mean duration of follow-up (and standard deviation) was 26 ± 21 months (range, three to 124 months). The mean gain (and standard deviation) in wrist extension with fingers extended was 67° ± 25° (range, -10° to 110°). Preoperatively, no hands were classified as Zancolli Group 1, whereas twenty-five hands were classified as Zancolli Group 1 at the latest follow-up review. Ten nonfunctional hands (rated as House Group 0 or Group 1) became functional as a supporting hand postoperatively. Zancolli and House classifications increased significantly (p contracture of the intrinsic muscles, which required further intervention. The Page-Scaglietti technique appears to improve range of motion and function in people with wrist and finger contractures due to central nervous system disorders.

Full Text Available The modified Thomas test was developed to assess the presence of hip flexion contracture and to measure hip extensibility. Despite its widespread use, to the authors’ knowledge, its criterion reference validity has not yet been investigated. The purpose of this study was to assess the criterion reference validity of the modified Thomas test for measuring peak hip extension angle and hip extension deficits, as defined by the hip not being able to extend to 0º, or neutral. Twenty-nine healthy college students (age = 22.00 ± 3.80 years; height = 1.71 ± 0.09 m; body mass = 70.00 ± 15.60 kg were recruited for this study. Bland–Altman plots revealed poor validity for the modified Thomas test’s ability to measure hip extension, which could not be explained by differences in hip flexion ability alone. The modified Thomas test displayed a sensitivity of 31.82% (95% CI [13.86–54.87] and a specificity of 57.14% (95% CI [18.41–90.10] for testing hip extension deficits. It appears, however, that by controlling pelvic tilt, much of this variance can be accounted for (r = 0.98. When pelvic tilt is not controlled, the modified Thomas test displays poor criterion reference validity and, as per previous studies, poor reliability. However, when pelvic tilt is controlled, the modified Thomas test appears to be a valid test for evaluating peak hip extension angle.

Contractures are a prevalent and potentially severe complication in patients with neurologic disorders. Although heat, cold, and stretching are commonly used for treatment of contractures and/or spasticity (the cause of many contractures), the sequential effects of these modalities remain unclear. Using an established rat model with spinal cord injury with knee flexion contracture, we sought to determine what combination of heat or cold before stretching is the most effective for treatment of contractures derived from spastic paralyses and investigated which treatment leads to the best (1) improvement in the loss of ROM; (2) restoration of deterioration in the muscular and articular factors responsible for contractures; and (3) amelioration of histopathologic features such as muscular fibrosis in biceps femoris and shortening of the joint capsule. Forty-two adolescent male Wistar rats were used. After spasticity developed at 2 weeks postinjury, each animal with spinal cord injury underwent the treatment protocol daily for 1 week. Knee extension ROM was measured with a goniometer by two examiners blinded to each other's scores. The muscular and articular factors contributing to contractures were calculated by measuring ROM before and after the myotomies. We quantitatively measured the muscular fibrosis and the synovial intima length, and observed the distribution of collagen of skeletal muscle. The results were confirmed by a blinded observer. The ROM of heat alone (34° ± 1°) and cold alone (34° ± 2°) rats were not different with the numbers available from that of rats with spinal cord injury (35° ± 2°) (p = 0.92 and 0.89, respectively). Stretching after heat (24° ± 1°) was more effective than stretching alone (27° ± 3°) at increasing ROM (p contractures. Although quantification of muscular fibrosis in the rats with spinal cord injury (11% ± 1%) was higher than that of controls (9% ± 0.4%) (p = 0.01), no difference was found between spinal cord

Context: Severe post burns contracture in children not only leads to functional impairment but also has profound psychological impact on the child. Untreated neck contractures have been shown to inhibit mandibular growth. Skin grafting in children has a higher rate of recurrence and in these cases a thin pliable flap seems to provide a durable solution. Aim: To study the feasibility of using primarily thinned free groin flap in the treatment of recurrent neck contractures in children. Materials and Methods: Five patients, in the age group of 5–10 years, with recurrent neck contractures and operated between 2005 and 2008 were included in this study. The sternomental distance, lateral flexion angle and cervicomental angle were measured preoperatively, postoperatively and during the subsequent follow-up visits. The patients were followed up for a period between 1 and 3 years with a mean of 29 months. Results: All the flaps survived. The cervicomental angle improved significantly to 90–105°, the lateral flexion angle improved to 35–45° and the sternomental distance increased considerably. Conclusions: Recurrent post burns contracture of the neck in children causes not only functional and aesthetic impairment but also psychological problems. A free microthinned groin flap provides a very attractive solution for this problem and should be seen as an effective alternative in recurrent cases. PMID:21321662

To explore causes of gluteal muscle contracture induced anterior knee pain and curative effect of arthroscopic release. From March 2002 to August 2013,36 patients with gluteal muscle contracture induced anterior knee pain were treated, including 15 males, 21 females, aged from 9 to 40 years old with an average (18.7±7.2) years old; the courses of diseases ranged from 4 to 30 years. The clinical manifestations involved limited to symmelia, positive Ober sign, buttocks touch contracture belts, knee and patella slide to lateral when doing squat activities. All patients were performed gluteal muscle contracture release under arthroscopic. Postoperative complications were observed, Kujala scoring before and after operation was used for compare curative effect. All patients were followed up with an average of 29 months. The incision were healed well, and no complications were occurred. Postoperative Kujala score were improved more than preoperative. Gluteal muscle contracture release could alleviate hypertension of lateral patella, and palys an important role in preventing patellofemoral arthritis.

Contracture after stroke could be due to abnormal mechanical interactions between muscles. This study examined if ankle plantarflexor muscle contracture after stroke is due to abnormal force transmission between the gastrocnemius and soleus muscles. Muscle fascicle lengths were measured from ultrasound images of soleus muscles in five subjects with stroke and ankle contracture and six able-bodied subjects. Changes in soleus fascicle length or pennation during passive knee extension at fixed ankle angle were assumed to indicate intermuscular force transmission. Changes in soleus fascicle length or pennation were adjusted for changes in ankle motion. Subjects with stroke had significant ankle contracture. After adjustment for ankle motion, 9 of 11 subjects demonstrated small changes in soleus fascicle length with knee extension, suggestive of intermuscular force transmission. However, the small changes in fascicle length may have been artifacts caused by movement of the ultrasound transducers. There were no systematic differences in change in fascicle length (median between-group difference adjusting for ankle motion = -0.01, 95% CI -0.26-0.08 mm/degree of knee extension) or pennation (-0.05, 95% CI -0.15-0.07 degree/ degree of knee extension). This suggests ankle contractures after stroke were not due to abnormal (systematically increased or decreased) intermuscular force transmission between the gastrocnemius and soleus.

Abstract Rationale: For localized type Volkmann's contracture, in which degeneration of the flexor digitorum profundus (FDP) muscle to one or two fingers and restriction of finger extension occur, dissection or excision of the affected muscle is usually recommended. However, these surgical procedures need relatively wide exposure of the muscle, because the FDP muscle is in the deep portion of the forearm. Patient concerns: In this report, the case of a 35-year-old woman with localized type Volkmann's contracture is presented. Her left forearm had been compressed with an industrial roller 4 months earlier, and severe flexion contracture of the long finger and mild flexion contracture of the ring finger developed gradually. Diagnoses: localized type Volkmann's contracture. Intervention: Five months after the injury, transection of the FDP tendon to the long finger and transfer of the transected tendon to the FDP tendon to the index finger was performed after adjusting the tonus of these two tendons using a small skin incision. This procedure was followed by a tension-reduced early mobilization technique in which a tension-reduced position of the tendon suture site was maintained by taping the long finger to the volar side of the index finger, and then immediate active range of motion (ROM) exercise was started. Outcomes: Within 9 weeks after surgery, full ROM had been regained. Lessons: Using the treatment procedure presented in this case report, a good clinical result was obtained in a minimally invasive manner. PMID:28072735

Superior oblique palsy is accompanied in most cases by overaction of the muscle's ipsilateral antagonist, the inferior oblique muscle. Overaction and contracture of the ipsilateral superior rectus muscle in patients with unilateral fourth (trochlear) nerve palsy is seldom discussed in the literature. The purpose of this study is to evaluate the frequency of superior rectus muscle overaction/contracture syndrome in patients with unilateral trochlear nerve palsy. The records of 198 patients with unilateral trochlear nerve palsy examined by the authors between July 1987 and July 2008 were reviewed retrospectively. All patients underwent complete eye examination with measurement of the deviation in the 9 positions of gaze and with the head tilted to both sides in all cooperative patients. Selection criteria for superior rectus muscle overaction/contracture syndrome in these patients were as follows: vertical deviation of 15(Delta) or larger in primary position, equal or larger hypertropia with the ipsilateral forced tilt test than with the eyes looking straight ahead, more than 5(Delta) hypertropia of the affected eye in horizontal gaze to the same side, hypertropia in all upgazes, and overaction of the contralateral superior oblique muscle. Of 198 patients, 33 (16.6%) met the selection criteria for superior rectus muscle overaction/contracture syndrome. Superior rectus muscle overaction/contracture syndrome frequently occurs in unilateral superior oblique palsy.

Scar contracture deformity, which can lead to dysfunction of hand and low quality of life, is one of the common complication after hand burns. The prevention measures of scar contracture after hand burns include large skin grafting, prevention of infection, insistence on wearing pressure gloves, use of silicone sheets, wearing orthosis, accepting proper physical therapy, and early functional exercise. The primary treatments of postburn contractures of the hand are surgery, drugs, laser treatment, and rehabilitation therapy. Excision of scars, release of muscle, joints or bones, and soft tissue transplantation are the core of surgery. Laser treatment has a bright future but still needs to be further studied. Additionally, some novel treatments such as molecular targeted therapy, cell therapy, fat injection, and botulinum toxin injection will play important roles in prevention and treatment of postburn contractures in the future. The purpose of this article is to review the literature concerning postburn contractures of the hand, and summarize the present situation of prevention and treatment of such disease comprehensively.

Full Text Available Abstract Background Development of hip adductor, tensor fascia lata, and rectus femoris muscle contractures following total hip arthroplasties are quite common, with some patients failing to improve despite treatment with a variety of non-operative modalities. The purpose of the present study was to describe the use of and patient outcomes of botulinum toxin injections as an adjunctive treatment for muscle tightness following total hip arthroplasty. Methods Ten patients (14 hips who had hip adductor, abductor, and/or flexor muscle contractures following total arthroplasty and had been refractory to physical therapeutic efforts were treated with injection of botulinum toxin A. Eight limbs received injections into the adductor muscle, 8 limbs received injections into the tensor fascia lata muscle, and 2 limbs received injection into the rectus femoris muscle, followed by intensive physical therapy for 6 weeks. Results At a mean final follow-up of 20 months, all 14 hips had increased range in the affected arc of motion, with a mean improvement of 23 degrees (range, 10 to 45 degrees. Additionally all hips had an improvement in hip scores, with a significant increase in mean score from 74 points (range, 57 to 91 points prior to injection to a mean of 96 points (range, 93 to 98 at final follow-up. There were no serious treatment-related adverse events. Conclusion Botulinum toxin A injections combined with intensive physical therapy may be considered as a potential treatment modality, especially in difficult cases of muscle tightness that are refractory to standard therapy.

In this thesis, our purpose is to show that using physiotherapy on patients with hip dysplasia from the very beginning, in the first months of life, helps treating them faster. Common literature proposes to use physiotherapy on patients with hip dysplasia either after their recovery or in the terminal phase of recovery, claiming that any earlier intervention will prolong the hip recovery. The effects of hip dysplasia reflect over the whole musculoskeletal system, while it hinders the knees (g...

The aim of this study was to examine changes in passive length and stiffness of the gastrocnemius muscle-tendon unit in people after spinal cord injury. In a prospective longitudinal study, eight wheelchair-dependent participants with severe paralysis were assessed 3 and 12 mos after spinal cord injury. Passive torque-angle data were obtained as the ankle was slowly rotated through range at six knee angles. Differences in passive ankle torque-angle data recorded at different knee angles were used to derive passive length-tension curves of the gastrocnemius muscle-tendon unit. Ultrasound imaging was used to determine fascicle and tendon contributions to the muscle-tendon unit length-tension curves. The participants had ankle contractures (mean [SD] maximum passive ankle dorsiflexion angle, 88  degrees) 3 mos after spinal cord injury. Ankle range did not worsen significantly during the subsequent 9 mos (mean change, -5 degrees; 95% confidence interval, -16 to 6 degrees). There were no changes in the mean slack length or the stiffness of the gastrocnemius muscle-tendon unit or in the slack lengths of the fascicles or the tendon between 3 and 12 mos after spinal cord injury. There were no consistent patterns of the change in slack length or stiffness with the changes in ankle range in the data from the individual participants. This study, the first longitudinal study of muscle length and stiffness after spinal cord injury, showed that the length and the stiffness of the gastrocnemius did not change substantially between 3 and 12 mos after injury.

To demonstrate the technique and the outcomes of robot assisted Y-V plasty bladder neck reconstruction (RYVBNR). We present our technique for treatment of recalcitrant bladder neck contracture (BNC) in 7 patients who underwent RYVBNR at our institution between March 2016 and September 2017. Indication for the procedure was incomplete emptying, recurrent urinary tract infections, and dysuria. On follow-up, patients were assessed for clinical success by absence of infections, symptoms, and cystoscopic evaluation. Robotic assisted dissection is performed to open the space of Retzius and mobilize the bladder. The cystoscope is passed to the level of the BNC, and Firefly technology is used to localize the BNC. The BNC is incised anteriorly, and a V-shaped bladder flap is advanced into the BNC in a Y-V plasty fashion. We place a perioperative closed suction drain, which is removed before discharge, and a 22 Fr catheter, which that will be removed in the office at approximately 2 weeks. Six men developed recalcitrant BNCs and 1 developed a recalcitrant vesicourethral anastomotic stenosis. All patients had previously undergone an endoscopic procedure. Median time for last attempt at endoscopic management to robot-assisted bladder neck repair was 4.7 months. The average number of prior attempts at endoscopic management was 2. All patients underwent RYVBNR without conversion to open surgery. The median operative time was 240 minutes, estimated blood loss was 67 mL, and length of stay was 1 day. There were no intraoperative complications. Catheters were removed in the office at a median time of 15 days. At a median follow-up of 8 months, all cases were successful with no evidence of recurrence. Only 2 patients had persistent urinary incontinence at 1 pad per day. RYVBNR with a Y-V plasty is a feasible and effective technique for managing a difficult reconstructive problem. Copyright © 2018 Elsevier Inc. All rights reserved.

Results. Executed tests shown that 47,5% from examined group of children have fault posture. Occurrence of hamstrings contracture, which was diagnosed in 40%, disrupts pelvis balance causing oblique position of pelvis. Conclusion. 1. Posture faults are major problem in our population. During examination near half of the group possessed at least one of the fault posture. 2. Hamstrings contracture disrupts pelvis balance causing oblique position of pelvis. Further it leads to increase frequency of fault posture. 3. Proper rehabilitation can prevent hamstring contracture, in advance prevents also occurrence of fault posture. 4. Rehabilitation study, in which analysis of specified anthropometric points and a few functional tests will be a component, can detect and correct diagnose fault posture among children.

The elbow joint is highly susceptible to joint contracture, and treating elbow contracture is a challenging clinical problem. Previously, we established an animal model to study elbow contracture that exhibited features similar to the human condition including persistent decreased range of motion (ROM) in flexion-extension and increased capsule thickness/adhesions. The objective of this study was to mechanically quantify pronation-supination in different injury models to determine if significant differences compared to control or contralateral persist long-term in our animal elbow contracture model. After surgically inducing soft tissue damage in the elbow, Injury I (anterior capsulotomy) and Injury II (anterior capsulotomy with lateral collateral ligament transection), limbs were immobilized for 6 weeks (immobilization (IM)). Animals were evaluated after the IM period or following an additional 6 weeks of free mobilization (FM). Total ROM for pronation-supination was significantly decreased compared to the uninjured contralateral limb for both IM and FM, although not different from control limbs. Specifically, for both IM and FM, total ROM for Injury I and Injury II was significantly decreased by ∼20% compared to contralateral. Correlations of measurements from flexion-extension and pronation-supination divulged that FM did not affect these motions in the same way, demonstrating that joint motions need to be studied/treated separately. Overall, injured limbs exhibited persistent motion loss in pronation-supination when comparing side-to-side differences, similar to human post-traumatic joint contracture. Future work will use this animal model to study how elbow periarticular soft tissues contribute to contracture.

The aim of this study is to clarify the following two points: First, whether a cyclooxygenase-2 mediated pathway is involved in the formation of immobilization-induced joint contracture and, second, the effectiveness of oral administration of non-steroidal anti-inflammatory drug celecoxib (CBX) for the prevention of myogenic and arthrogenic contracture following immobilization in a rat model. Thirty male rats were randomly divided into three groups: immobilization (Im), Im + CBX, and control (n = 10 each). External fixation immobilized the right knee joint of Im and Im + CBX groups in flexion for 3 weeks. 50 mg/kg of CBX was administrated daily to the Im + CBX group during this period. The passive range of motion (ROM) of knee joints was measured before and after transection of knee flexor muscles and myogenic and arthrogenic ROM restrictions were calculated. The semitendinosus muscles and knee joints were investigated histologically to elucidate factors responsible for contracture. Myogenic ROM restrictions were exhibited both in Im and Im + CBX groups (44 ± 5 and 36 ± 8 °, respectively), but restrictions significantly decreased in the Im + CBX group compared to the Im group. Significant reductions of the muscle length ratios (Rt/Lt) and sarcomere number ratios (Rt/Lt) in knee flexor semitendinosus muscle, which are responsible for myogenic contracture, were also seen both in Im group (92 ± 5 and 92 ± 4 %, respectively) and Im + CBX group (97 ± 3 and 97 ± 3 %, respectively), but were inhibited by CBX administration (P muscle shortening following immobilization. These results imply that inflammation and nociception are involved in myogenic contracture formation independently of joint immobilization, and that CBX is effective in preventing joint contracture following immobilization in rats.

To investigate the effectiveness of dorsal metacarpal island flap for treating scar contracture of the finger web. Between June 2009 and December 2010, 10 patients with scar contracture of the finger web were treated. There were 6 males and 4 females with an average age of 30 years (range, 14-57 years). Scar contracture was caused by injury in 8 cases, by burn in 1 case, and by operation in 1 case. The locations were the 1st web space in 1 case, the 2nd web space in 3 cases, the 3rd web space in 5 cases, and the 4th web space in 1 case. The disease duration was 3 to 9 months with an average of 5 months. The maximum abduction was 10-20 degrees. After web space scar release, the dorsal metacarpal island flap (3.5 cm x 1.2 cm-4.0 cm x 2.0 cm in size) was used to reconstruct web space (2.0 cm x 1.0 cm-3.0 cm x 1.8 cm in size). The donor site was directly sutured or repaired with local flaps. At 2 days after operation, necrosis occurred in 1 flap, which healed by extractive treatment. The other flaps survived and wound healed by first intention; all the flaps at donor sites survived and incision healed by first intention. Ten patients were followed up 6 to 15 months (mean, 9 months). The reconstructed web space had good appearance, the maximum abduction was 80 degrees in 1 case of the 1st web space scars contracture, and the maximum abduction was 35-45 degrees (mean, 40 degrees) in the other 9 cases. In 8 scar patients causing by injury, no scar contracture recurred during follow-up. It can achieve good results in appearance and function to use dorsal metacarpal island flap for treating scar contracture of the finger web.
Full Text Available Severe post burn neck contracture results in difficult intubation, which can be life threatening and can result in multiple serious complications and sequels. Thirty patients with age ranging from 12 to 50 years were operated under local tumescent anesthesia supplemented with intravenous ketamine for release of post burn neck contracture and split skin grafted. This technique obviates the need for endotracheal intubation. There were no complications attributed to this anesthesia technique. There was no graft loss and blood loss was minimal.

Spasticity is a frequent complication after severe brain injury, which may prevent the rehabilitation process and worsen the patients' quality of life. In this study, we investigated the correlation between spasticity, muscle contracture, and the frequency of physical therapy (PT) in subacute and chronic patients with disorders of consciousness (DOC). 109 patients with subacute and chronic disorders of consciousness (Vegetative state/Unresponsive wakefulness syndrome - VS/UWS; minimally conscious state - MCS and patients who emerged from MCS - EMCS) were included in the study (39 female; mean age: 40±13.5y; 60 with traumatic etiology; 35 VS/UWS, 68 MCS, 6 EMCS; time since insult: 38±42months). The number of PT sessions (i.e., 20 to 30 minutes of conventional stretching of the four limbs) was collected based on patients' medical record and varied between 0 to 6 times per week (low PT = 0-3 and high PT = 4-6 sessions per week). Spasticity was measured with the Modified Ashworth Scale (MAS) on every segment for both upper (UL) and lower limbs (LL). The presence of muscle contracture was assessed in every joint. We tested the relationship between spasticity and muscle contracture with the frequency of PT as well as other potential confounders such as time since injury or anti-spastic medication intake. We identified a negative correlation between the frequency of PT and MAS scores as well as the presence of muscle contracture. We also identified that patients who received less than four sessions per week were more likely to be spastic and suffer from muscle contracture than patients receiving 4 sessions or more. When separating subacute (3 to 12 months post-insult) and chronic (>12months post-insult) patients, these negative correlations were only observed in chronic patients. A logit regression model showed that frequency of PT influenced spasticity, whereas neither time since insult nor medication had a significant impact on the presence of spasticity. On

Mohs' micrographic surgery (MMS) is an effective means of margin control in the management of periocular basal cell carcinomas (BCC). We describe three cases of recurrent BCC that presented with progressive eyelid contracture after MMS. They illustrate high-risk factors for recurrence, namely large tumor size, medial canthal location, previous treatment, and aggressive histological features. Careful long-term surveillance with serial photography may identify early eyelid contracture and thus assist in the detection of recurrent BCC after MMS and improve patient outcome.

Full Text Available Lumbosacral spine and hip joints is a complex physiological functions of the co-operation of a large number of anatomical structures. Lesions of the links in the system can mutually afflict each other. Combined pathology of the hip and lumbosacral spine is called hip-spine syndrome, or coxa-vertebral syndrome. Symptoms of the joint and spine are very similar and only a careful examination and clinical examination may find the differences. As the disease progresses the hip increases the restriction of movement, there is a contracture of the limbs in a vicious position, which leads to an increase in tilt of the pelvis, increased lumbar lordosis and to functional shortening of limbs on the affected side. This gives rise to functional impairment, and then strain the joints of his spine and disease - osteochondrosis and scoliosis. After the successful operation of total hip replacement is often progressive clinical lesions of vertebral segment, which is manifested pain and is often offset by the results of arthroplasty as the restoration of movement in the hip joint, and the change in length limb after arthroplasty leads to rupture formed a functional stereotype change in the mobility of the lumbar spine, pelvis regression bias that causes the dynamic compression spinal nerve root. Depending on the duration of the existence, severity and nature of changes in the pelvic girdle is suitable correction of equipment replacement surgery, including, for example, in some cases, deliberate shortening or lengthening the preservation of the lower extremity, offset change, etc.

Currently, magnetic resonance imaging is considered the accepted standard to evaluate breast implant integrity. To evaluate its utility in diagnosing ruptured silicone implants in the setting of capsular contracture and to correlate the preoperative assessment of implant integrity with or without magnetic resonance imaging with operative findings, 319 capsulectomies (171 patients with capsular contractures) were retrospectively reviewed. Preoperative magnetic resonance imaging was done on 160 implants, whereas the remaining 159 were evaluated using only physical examination and/or mammography. Postoperative results were analyzed to determine the sensitivity, specificity, and accuracy of preoperative magnetic resonance imaging in comparison with clinical and/or mammography evaluation alone. Although occasionally valuable, overall, preoperative magnetic resonance imaging was no more accurate than clinical evaluation with or without mammography in predicting implant status: magnetic resonance imaging 124 of 160 (78 percent) and clinical 121 of 159 (76 percent; p = 0.77). In the setting of capsular contracture, physical examination with or without mammogram is as accurate as magnetic resonance imaging in determining implant integrity. Although magnetic resonance imaging is a sensitive diagnostic tool, in symptomatic patients with capsular contracture, it cannot be viewed as infallible.

Arthrogryposis multiplex congenita is a heterogeneous group of disorders characterized by multiple contractures with an estimated frequency of 1 in 3,000 births. With improving diagnostic methods, increasing numbers of fetuses with arthrogryposis are found. The pathogenetic mechanisms are relatively well known but the epidemiology and genetics of the prenatally lethal forms of arthrogryposis are less well known. In this study we collected all cases of a multiple contractures diagnosed in Finland during 1987-2002 including live born infants, stillbirths, and terminated pregnancies. Ninety-two cases of 214 suffered intrauterine demise (68 selective pregnancy terminations and 24 stillbirths) and 58 died in infancy. In 141 out of these cases the diagnosis could be included within lethal arthrogryposes, with a prevalence of 1 in 6,985 (1.43/10,000) births. Of these, 59 had spinal cord pathology at autopsy and thus were of neurogenic origin. Thirty-nine cases had lethal congenital contracture syndrome (LCCS) clinically characterized by total immobility of the fetus at all ultrasound examinations (12 weeks or later), multiple joint contractures in both upper and lower limbs, hydrops, and fetal death before the 32nd week of pregnancy. LCCS is noted as a unique Finnish disorder with a prevalence of 1 in 25,250 (0.40/10,000) births and is a major cause of lethal arthrogryposis in Finland.

Muscle diseases may have various clinical manifestations including muscle weakness, atrophy or hypertrophy and joint contractures. A spectrum of non-muscular manifestations (cardiac, respiratory, cutaneous, central and peripheral nervous system) may be associated. Few of these features are specific. Limb joint contractures or spine rigidity, when prevailing over muscle weakness in ambulant patients, are of high diagnostic value for diagnosis orientation. Within this context, among several disorders, four groups of diseases should systematically come to mind including the collagen VI-related myopathies, the Emery-Dreifuss muscular dystrophies, the SEPN1 and FHL1 related myopathies. More rarely other genetic or acquired myopathies may present with marked contractures. Diagnostic work-up should include a comprehensive assessment including family history, neurological, cardiologic and respiratory evaluations. Paraclinical investigations should minimally include muscle imaging and electromyography. Muscle and skin biopsies as well as protein and molecular analyses usually help to reach a precise diagnosis. We will first describe the main muscle and neuromuscular junction diseases where contractures are typically a prominent symptom of high diagnostic value for diagnosis orientation. In the following chapters, we will present clues for the diagnostic strategy and the main measures to be taken when, at the end of the diagnostic work-up, no definite muscular disease has been identified.

To investigate the mechanisms of contracture after stroke by comparing passive mechanical properties of gastrocnemius muscle-tendon units, muscle fascicles, and tendons in people with ankle contracture after stroke with control participants. Cross-sectional study. Laboratory in a research institution. A convenience sample of people with ankle contracture after stroke (n=20) and able-bodied control subjects (n=30). Not applicable. Stiffness and lengths of gastrocnemius muscle-tendon units, lengths of muscle fascicles, and tendons at specific tensions. At a tension of 100N, the gastrocnemius muscle-tendon unit was significantly shorter in participants with stroke (mean, 436mm) than in able-bodied control participants (mean, 444mm; difference, 8mm; 95% confidence interval [CI], 0.2-15mm; P=.04). Muscle fascicles were also shorter in the stroke group (mean, 44mm) than in the control group (mean, 50mm; difference, 6mm; 95% CI, 1-12mm; P=.03). There were no significant differences between groups in the mean stiffness or length of the muscle-tendon units and fascicles at low tension, or in the mean length of the tendons at any tension. People with ankle contracture after stroke have shorter gastrocnemius muscle-tendon units and muscle fascicles than control participants at high tension. This difference is not apparent at low tension. Copyright © 2012 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Full Text Available Case series summary Three cats, Siamese or Siamese cross, were presented with a chronic thoracic limb weightbearing lameness. Previous anti-inflammatory administrations were unable to improve lameness consistently in the three cats. Two of the three cats had undergone onychectomy several years before presentation. A permanent flexion of the proximal interphalangeal joint of one or more digits, associated with a difficult and painful extension of the proximal interphalangeal joint, was noticed during orthopedic examination. A digital flexor tendon contracture was suspected and confirmed with radiographic examination. Surgical exploration was then performed. For all cats, treatment consisted of a tenectomy or tenotomy of the superficial and deep digital flexor tendons in order to release the contracture. The three cats responded well to the surgical treatment and became sound around 2–4 weeks after surgery. Relevance and novel information Digital flexor tendon contracture is rarely reported as a cause of lameness in cats. It should be considered in a differential diagnosis of feline lameness whenever onychectomy has been performed in the past. The precise etiology that explains this tendon contracture is unknown, but trauma or breed predisposition could represent potential causes.

Burn contractures are common and difficult to treat. Measuring continuous joint motion would inform the assessment of contracture interventions; however, it is not standard clinical practice. This study examines use of an interactive gaming system to measure continuous joint motion data. To assess the usability of an exoskeleton-based interactive gaming system in the rehabilitation of upper extremity burn contractures. Feasibility study. Eight subjects with a history of burn injury and upper extremity contractures were recruited from the outpatient clinic of a regional inpatient rehabilitation facility. Subjects used an exoskeleton-based interactive gaming system to play 4 different video games. Continuous joint motion data were collected at the shoulder and elbow during game play. Visual analog scale for engagement, difficulty and comfort. Angular range of motion by subject, joint, and game. The study population had an age of 43 ± 16 (mean ± standard deviation) years and total body surface area burned range of 10%-90%. Subjects reported satisfactory levels of enjoyment, comfort, and difficulty. Continuous joint motion data demonstrated variable characteristics by subject, plane of motion, and game. This study demonstrates the feasibility of use of an exoskeleton-based interactive gaming system in the burn population. Future studies are needed that examine the efficacy of tailoring interactive video games to the specific joint impairments of burn survivors.

The etiology of elbow flexion contracture in children with brachial plexus birth palsy remains unclear. We hypothesized that the long head of the biceps brachii muscle assists with shoulder stabilization in children with brachial plexus birth palsy and that overactivity of the long head during elbow and shoulder activity is associated with an elbow flexion contracture. Twenty-one patients with brachial plexus birth palsy-associated elbow flexion contracture underwent testing with surface electromyography. Twelve patients underwent repeat testing with fine-wire electromyography. Surface electrodes were placed on the muscle belly, and fine-wire electrodes were inserted bilaterally into the long and short heads of the biceps brachii. Patients were asked to perform four upper extremity tasks: elbow flexion-extension, hand to head, high reach, and overhead ball throw. The mean duration of muscle activity in the affected limb was compared with that in the contralateral, unaffected limb, which was used as a control. Three-dimensional motion analysis, surface dynamometry, and validated function measures were used to evaluate upper extremity kinematics, elbow flexor-extensor muscle imbalance, and function. The mean activity duration of the long head of the biceps brachii muscle was significantly higher in the affected limb as compared with the contralateral, unaffected limb during hand-to-head tasks (p = 0.02) and high-reach tasks (p = 0.03). No significant differences in mean activity duration were observed for the short head of the biceps brachii muscle between the affected and unaffected limbs. Isometric strength of elbow flexion was not significantly higher than that of elbow extension in the affected limb (p = 0.11). Overactivity of the long head of the biceps brachii muscle is associated with and may contribute to the development of elbow flexion contracture in children with brachial plexus birth palsy. Elbow flexion contracture may not be associated with an elbow

Increased resistance in muscles and joints is an important phenomenon in patients with cerebral palsy (CP), and is caused by a combination of neural (e.g. spasticity) and non-neural (e.g. contracture) components. The aim of this study was to simulate instrumented, clinical assessment of the hamstring muscles in CP using a conceptual model of contracture and spasticity, and to determine to what extent contracture can be explained by altered passive muscle stiffness, and spasticity by (purely) velocity-dependent stretch reflex. Instrumented hamstrings spasticity assessment was performed on 11 children with CP and 9 typically developing children. In this test, the knee was passively stretched at slow and fast speed, and knee angle, applied forces and EMG were measured. A dedicated OpenSim model was created with motion and muscles around the knee only. Contracture was modeled by optimizing the passive muscle stiffness parameters of vasti and hamstrings, based on slow stretch data. Spasticity was modeled using a velocity-dependent feedback controller, with threshold values derived from experimental data and gain values optimized for individual subjects. Forward dynamic simulations were performed to predict muscle behavior during slow and fast passive stretches. Both slow and fast stretch data could be successfully simulated by including subject-specific levels of contracture and, for CP fast stretches, spasticity. The RMS errors of predicted knee motion in CP were 1.1 ± 0.9° for slow and 5.9 ± 2.1° for fast stretches. CP hamstrings were found to be stiffer compared with TD, and both hamstrings and vasti were more compliant than the original generic model, except for the CP hamstrings. The purely velocity-dependent spasticity model could predict response during fast passive stretch in terms of predicted knee angle, muscle activity, and fiber length and velocity. Only sustained muscle activity, independent of velocity, was not predicted by our model. The

We used an established mouse model of elbow flexion contracture after neonatal brachial plexus injury (NBPI) to test the hypothesis that preservation of afferent innervation protects against contractures and is associated with preservation of muscle spindles and ErbB signaling. A model of preganglionic C5 through C7 NBPI was first tested in mice with fluorescent axons using confocal imaging to confirm preserved afferent innervation of spindles despite motor end plate denervation. Preganglionic and postganglionic injuries were then created in wild-type mice. Four weeks later, we assessed total and afferent denervation of the elbow flexors by musculocutaneous nerve immunohistochemistry. Biceps muscle volume and cross-sectional area were measured by micro computed tomography. An observer who was blinded to the study protocol measured elbow flexion contractures. Biceps spindle and muscle fiber morphology and ErbB signaling pathway activity were assessed histologically and immunohistochemically. Preganglionic and postganglionic injuries caused similar total denervation and biceps muscle atrophy. However, after preganglionic injuries, afferent innervation was partially preserved and elbow flexion contractures were significantly less severe. Spindles degenerated after postganglionic injury but were preserved after preganglionic injury. ErbB signaling was inactivated in denervated spindles after postganglionic injury but ErbB signaling activity was preserved in spindles after preganglionic injury with retained afferent innervation. Preganglionic and postganglionic injuries were associated with upregulation of ErbB signaling in extrafusal muscle fibers. Contractures after NBPI are associated with muscle spindle degeneration and loss of spindle ErbB signaling activity. Preservation of afferent innervation maintained spindle development and ErbB signaling activity, and protected against contractures. Pharmacologic modulation of ErbB signaling, which is being investigated as a

A proper co - ordination between them is needed for providing a hassle - free patient care. This is a prospective study done on 30 consecutive patients of post burn contractures of the neck to compare the surgeon’s assessment of the type and pattern of post - burn contracture of the neck and the anaesthesiologist’s assessment of the airway. T he association of this with the peri - operative management of patients was also studied. The data analysed was type of contracture , mento - sternal distance , and preoperative grading of the airway. The method of securing intra - operative airway was documented . A direct co - relation was noted between the type of contracture with the Mallampatti grading of the airway and the sterno - mental distance. All type III contractures required release before intubation. In conclusion , it is advisable for the surgeon to be w ell - versed with the anaesthesiologist’s assessment of the airway and the anaesthesiologist to aware of the types of neck contracture in order to properly plan and execute the peri - operative management of these patients.

The imaging evaluation of the prosthetic hip begins with radiography, but arthrography, aspiration, scintigraphy, sonography, CT and MR imaging all have roles in the evaluation of the painful prosthesis. This article will review the appearance of normal hip arthroplasty including hemiarthroplasty, total arthroplasty, and hip resurfacing, as well as the appearances of potential complications such as aseptic loosening and osteolysis, dislocation, infection, periprosthetic fracture, hardware failure, and soft tissue abnormalities.

The purpose of this study was to analyze the association between functioning and disability and quality of life (QoL) in older individuals with joint contractures in the geriatric care setting. More specifically, this study aimed to identify determinants of QoL out of a defined set of contracture-related categories of the International Classification of Functioning, Disability and Health (ICF). Participants for this multicenter cross-sectional survey were recruited from acute geriatric rehabilitation hospitals, nursing homes, and community nursing facilities in Germany between February and October 2013. QoL was assessed using the validated German version of the EQ-5D index score and the EQ-5D visual analog scale (VAS). Manual and automatic variable selection methods were used to identify the most relevant variables out of 125 contracture-related ICF categories. A total of 241 eligible participants (34.9 % male, mean age 80.1 years) were included. The final models contained 14 ICF categories as predictors of the EQ-5D index score and 15 categories as predictors of the EQ-5D VAS. The statistically significant ICF categories from both models were 'muscle power functions (b730),' 'memory functions (b144),' 'taking care of plants (d6505),' 'recreation and leisure (d920),' 'religion and spirituality (d930),' 'drugs (e1101),' and 'products and technology for personal use in daily living (e115).' We identified the most relevant ICF categories for older individuals with joint contractures and their health-related quality of life. These items describe potential determinants of QoL which may provide the basis for future health interventions aiming to improve QoL for the patients with joint contractures.

Satellite cells are the stem cells residing in muscle responsible for skeletal muscle growth and repair. Skeletal muscle in cerebral palsy (CP) has impaired longitudinal growth that results in muscle contractures. We hypothesized that the satellite cell population would be reduced in contractured muscle. We compared the satellite cell populations in hamstring muscles from participants with CP contracture (n=8; six males, two females; age range 6-15y; Gross Motor Function Classification System [GMFCS] levels II-V; 4 with hemiplegia, 4 with diplegia) and from typically developing participants (n=8; six males, two females, age range 15-18y). Muscle biopsies were extracted from the gracilis and semitendinosus muscles and mononuclear cells were isolated. Cell surface markers were stained with fluorescently conjugated antibodies to label satellite cells (neural cell adhesion molecule) and inflammatory and endothelial cells (CD34 and CD4 respectively). Cells were analyzed using flow cytometry to determine cell populations. After gating for intact cells a mean of 12.8% (SD 2.8%) were determined to be satellite cells in typically developing children, but only 5.3% (SD 2.3%; p0.05) suggesting the isolation procedure was valid. A reduced satellite cell population may account for the decreased longitudinal growth of muscles in CP that develop into fixed contractures or the decreased ability to strengthen muscle in CP. This suggests a unique musculoskeletal disease mechanism and provides a potential therapeutic target for debilitating muscle contractures. © The Authors.

Altered neural control of movement and musculoskeletal deficiencies are common in children with spastic cerebral palsy (SCP), with muscle weakness and contracture commonly experienced. Both neural and musculoskeletal deficiencies are likely to contribute to abnormal gait, such as equinus gait (toe-walking), in children with SCP. However, it is not known whether the musculoskeletal deficiencies prevent normal gait or if neural control could be altered to achieve normal gait. This study examined the effect of simulated muscle weakness and contracture of the major plantarflexor/dorsiflexor muscles on the neuromuscular requirements for achieving normal walking gait in children. Initial muscle-driven simulations of walking with normal musculoskeletal properties by typically developing children were undertaken. Additional simulations with altered musculoskeletal properties were then undertaken; with muscle weakness and contracture simulated by reducing the maximum isometric force and tendon slack length, respectively, of selected muscles. Muscle activations and forces required across all simulations were then compared via waveform analysis. Maintenance of normal gait appeared robust to muscle weakness in isolation, with increased activation of weakened muscles the major compensatory strategy. With muscle contracture, reduced activation of the plantarflexors was required across the mid-portion of stance suggesting a greater contribution from passive forces. Increased activation and force during swing was also required from the tibialis anterior to counteract the increased passive forces from the simulated dorsiflexor muscle contracture. Improvements in plantarflexor and dorsiflexor motor function and muscle strength, concomitant with reductions in plantarflexor muscle stiffness may target the deficits associated with SCP that limit normal gait.

Full Text Available In this thesis, our purpose is to show that using physiotherapy on patients with hip dysplasia from the very beginning, in the first months of life, helps treating them faster. Common literature proposes to use physiotherapy on patients with hip dysplasia either after their recovery or in the terminal phase of recovery, claiming that any earlier intervention will prolong the hip recovery. The effects of hip dysplasia reflect over the whole musculoskeletal system, while it hinders the knees (genu valgum, the ankles (ankle valgus, calcaneal valgus and the spine (scoliosis especially at the lumbar level. The most spectacular are at the hip level, that is why we made an analytical evaluation only for this joint. To show the importance of physiotherapy for children with hip dysplasia we started from the hypothesis: untimely treatment for children with hip dysplasia has improved results in functional recovery and in obtaining a better stability, without the necessity of orthopedics or surgical interventions. The research methods used in this study are: the observation method, the bibliographic study method, the experimental method, the graphics method and the statistical mathematical method to process the data and to represent the results graphically. In the end, the results obtained are significantly different from the initial evaluations and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient improves stability and biomechanical parameters for the hip.

Alkaptonuria is a metabolic disorder in which homogentisic acid oxidase is absent. Therefore, homogentisic acid accumulates in cartilage and connective tissues. We can diagnose ochronotic arthropathy, a manifestation of long standing alkaptonuria, through careful radiological, physical, and laboratory examination. In this report, we describe 4 cases of ochronotic arthropathy to which we applied cementless total hip prosthesis due to severe hip involvement. (author)

Full Text Available Soft tissue defect will form after operative treatment of the dermato-desmogenic flexion contractures of fingers interphalangeal joints of the 2–3 grades after excision of the scar. Using the island flaps (Littler at the central vascular pedicle is one of the classical methods of plastic closure of such defects. Goal. To study the effectiveness of the surgical treatment of dermato-desmogenic flexion contractures of proximal interphalangeal joints of the fingers by using finger island flaps at the central vascular or neuro-vascular pedicle. Materials and methods. 14 operations were carried out on 13 patients for removing dermato-desmogenic flexion contractures of proximal interphalangeal (PIP joints of triphalangeal fingers over a 2-year period (2013–2015. The group included patients with a flexion contracture of the 2–3 grades PIP joints of triphalangeal fingers. Operations were performed on average 5 months after the injury (from 1.5 up to 16 months. Finger island flap in all cases was taken from adjacent finger by using the blood supply of their common finger artery. In all cases the island flap on the central pedicel was used, in 9 cases digital nerve was included in the pedicle (Littler. Closure of donor wound was made with free-skin grafts. Permanent splinting of the hand with extension of the interphalangeal joints and moderate flexion of the metacarpophalangeal joints were performed during 7–8 days after surgery, then exercise therapy was prescribed. Results. The results were estimated 6 and 12 months after surgery. All the results were regarded as excellent. In 5 cases of using the flap on a vascular pedicle flap hypoesthesia was detected, that has not led to dysfunction of the hand. Contracture recurrence during follow-up was not observed. Conclusions. Using the surgery for treatment of dermato-desmogenic flexion contractures of proximal interphalangeal joints of the fingers with the island flaps at the central vascular or neuro

Purpose: Serial casting for ankle contractures is traditionally performed in prone, a position that patients may not easily tolerate. Also, although serial casting is effective in correcting contracture, its effect dissipates quickly. This case report describes a procedure for performing casting for ankle contractures in a supine or sitting position. It also describes a process that enables the effect of serial casting to be maintained long term. Client Description: The client was an adult who had suffered traumatic brain injury and severe bilateral ankle contractures. Intervention: He received botulinum toxin and serial casting for his bilateral ankle contractures, one ankle at 8 months and the other at 13 months after the injury. He then underwent a programme of splinting and motor training. Measures and Outcome: The client gained more than 40° dorsiflexion for both ankles after receiving botulinum toxin injections and serial casting. The improvement in ankle range enabled him to progress to walking practice. Ankle splinting was gradually reduced. On discharge at 25 months post-injury, the ankle joint range was maintained. Implications: The use of botulinum toxin and serial casting, followed by an intensive programme of splinting and motor training, may be an option to consider for effective long-term resolution of severe contractures after acquired brain injury.

Assessment of surgical outcomes of biceps tendon lengthening (BTL) surgery in obstetric brachial plexus injury (OBPI) patients with elbow flexion contractures, who had unsuccessful serial casting. Serial casting and splinting have been shown to be effective in correcting elbow flexion contractures in OBPI. However, the possibilities of radial head dislocations and other complications have been reported in serial casting and splinting. Literature indicates surgical intervention when such nonoperative techniques and range-of-motion exercises fail. Here, we demonstrated a significant reduction of the contractures of the affected elbow and improvement in arm length to more normal after BTL in these patients, who had unsuccessful serial casting. Ten OBPI patients (6 girls and 4 boys) with an average age of 11.2 years (4-17.7 years) had BTL surgery after unsuccessful serial casting. Mean elbow flexion contracture was 40° before and 37° (average) after serial casting. Mean elbow flexion contracture was reduced to 8° (0°-20°) post-BTL surgical procedure with an average follow-up of 11 months. This was 75% improvement and statistically significant (P casting. These OBPI patients in our study had 75% significant reduction in elbow flexion contractures and achieved an improved and more normal length of the affected arm after the BTL surgery when compared to only 7% insignificant reduction and no improvement in arm length after serial casting.

To investigate the effect of delayed skin grafting combined traction in severe joint cicatricial contracture. At the first stage, the joint cicatricial contracture was released completely with protection of vessels, nerves and tendons. The wound was covered with allogenetic skin or biomaterials. After skin traction for 7-14 days, the joint could reach the extension position. Then the skin graft was performed on the wound. 25 cases were treated from Mar. 2000 to May. 2013. Primary healing was achieved at the second stage in all the cases. The skin graft had a satisfactory color and elasticity. Joint function was normal. All the patients were followed up for 3 months to 11 years with no hypertrophic scar and contraction relapse, except for one case who didn' t have enough active exercise on shoulder joint. Delayed skin grafting combined traction can effectively increase the skin graft survival rate and improve the joint function recovery.
Full Text Available An 8-year-old boy, diagnosed as cervical dystonia, was referred to our tertiary center. After a trivial trauma he had developed painful lumps in the axial region, which was followed by restricted movements of neck, shoulder, and abdominal muscles over 4 months. He had kyphoscoliosis, torticollis, rigid abdomen, and multiple muscle contractures. He also had short great toes. A detailed skeletal survey showed calcification in the soft tissues surrounding the shoulder anterior chest wall, thorax, and paraspinal muscles; there was also beaking of vertebrae, which was confirmed by CT thorax. This report showcases the diagnostic challenge posed by myositis ossificans progressiva, which can rarely cause rapidly progressing muscle contractures. A brief review of literature is also presented.

Bethlem myopathy and Ullrich congenital muscular dystrophy form a spectrum of collagenopathies caused by genetic mutations encoding for any of the three subunits of collagen VI. Bethlem phenotype is relatively benign and is characterized by proximal dominant myopathy, keloids, contractures, distal hyperextensibility, and follicular hyperkeratosis. Three patients from a single family were diagnosed to have Bethlem myopathy based on European Neuromuscular Centre Bethlem Consortium criteria. Affected father and his both sons had slowly progressive proximal dominant weakness and recurrent falls from the first decade. Both children aged 18 and 20 years were ambulant at presentation. All had flexion contractures, keloids, and follicular hyperkeratosis without muscle hypertrophy. Creatinine kinase was mildly elevated and electromyography revealed myopathic features. Muscle imaging revealed severe involvement of glutei and vasti with "central shadow" in rectus femoris. Muscle biopsy in the father showed dystrophic changes with normal immmunostaining for collagen VI, sarcoglycans, and dysferlin.

Full Text Available The acute compartment syndrome of the forearm is rare and may therefore be easily missed. Although many clinicians will not see such a patient during their entire career, profound knowledge of the symptoms is required to recognize the syndrome in time. Besides immediate identification of the compartment syndrome early surgical treatment is mandatory to avoid its devastating consequences. Then the functional results can be good, but it can't be correct in child because of more chance to survive necrotic muscle and regain motion with splinting and hand therapy. This study reported the nonsurgical treatment for ischemic contracture of hand and forearm due to displaced supra-condylar fracture of the humorous at 6 years old boy, after fixed contractures.

Dupuytren's disease (DD) is a fibroproliferative pathology that affects the palmar aponeurosis causing the development of nodules and collagen cords and the progressive flexion of the fingers. The standard procedure is surgical fasciectomy, followed by high recurrence rates. Collagenase Clostridium histolyticum (CCH) injection represents an innovative noninvasive approach to the treatment of DD. This prospective study was designed to examine the efficacy and safety of CCH injection performed in the outpatient, using local anesthesia. Forty patients [32 metacarpophalangeal (MP), 8 proximal interphalangeal (PIP)] with Dupuytren's contracture of at least 20° for MP joint and any degree for PIP joint were included. The mean age was 66. All joints were treated with a single vial of collagenase injection and manual breaking of the cord 24 h after. All adverse effects (AEs) were monitored. Patients were checked 7, 30, 90, and 180 days after the injection. Primary endpoint was a reduction in digit contracture within 0°-5° of normal extension. Secondary endpoints were the improvement of range of motion, the evaluation of AEs incidence, and cost-effectiveness of collagenase treatment. About 67.5 % of patients obtained a clinical success. At 6 months, a further 7.5% attained the same result. The mean contracture of treated joints was 5.3º for MP and 6.8° for PIP joints. Twenty-three patients had one or more mild-to-moderate side effects. The use of collagenase appears to be an effective and safe method for the treatment of Dupuytren's contracture. Therapeutic success was achieved in a significant percentage of patients. The incidence of side effects was higher, but they were local reactions of short duration. The use of a single collagenase vial in patients treated in day surgery appears more cost-effective than surgery.

Full Text Available Background: Joint contracture is a limitation in the passive or active range of motion (ROM of a joint, where in addition to the mobility limiting factor the pain is also present. Repetitive pulsed Magnetic Stimulation (rPMS appears to be an effective, non-invasive and safety solution for treating this condition. Therefore aim of this study was to evaluate the effect of rPMS in treating joint contracture. Methods: 30 subjects with joint contracture in the knee were enrolled in this study and divided respectively into Treatment and Control group. The treatment group were delivered with rPMS therapy. The control group was delivered with conventional physiotherapy method (ultrasound. The primary outcome measurements were: 1. Mobility evaluation by goniometry (ROM in degrees while performing flexion and Patient Functional Assessment Questionnaire (PFAQ for ability to perform Activities of Daily Living (ADL and 2. Pain evaluation by 10-point Visual Analog Scale (VAS for pain perception. Absence of adverse events was set as a secondary measure. Results: The results of the study show statistical difference (p<0.05 between the levels of improvement of all studied parameters while comparing between both groups. The results suggest greater immobility restoration and pain relieving effect of the rPMS in comparison to conventional physiotherapy method. Conclusion: rPMS an effective and safe non-invasive method for mobility restoration and pain relief in case of joint contractures. This study suggests the method as beneficial and quality of life ameliorating among patients suffering from immobilized joints accompanied by pain.

Reported is the case of a 68-year-old male presenting with severe wrist and hand stiffness following surgery for a Dupuytren's contracture. Complications of surgery or rehabilitation and complex regional pain syndrome were excluded as factors explaining this stiffness. Given the patient's diabetes mellitus and the striking similarity with the typical diabetic stiff hand, it is suggested that diabetes may have contributed to the development of the complication.

Full Text Available Objective. Improvement of surgical treatment outcomes in children with post-traumatic elbow contractures. Materials and methods. The study is based on the diagnostic findings of 48 children with post-traumatic elbow contractures who were treated at the Turner Scientific and Research Institute for Children’s Orthopedics. All children underwent complex rehabilitation after reconstructive intra-articular surgery to work out passive motions in the elbow using ARTROMOT-E2 device. The patients of the study group started rehabilitation in the first days after reconstructive intra-articular surgery in the background of prolonged blockade of the brachial plexus. In the control group, the rehabilitation was carried out traditionally on the 6th day after surgery without regional anesthesia. The patients of the study group were supplied with Contiplex SU perinural catheters for prolonged blockade of the brachial plexus using ultrasound (Edge SonoSite and neurostimulation (Stimuplex® HNS12 before surgery. For perioperative blockade of the brachial plexus we used intermittent injection of 0.5% ropivacaine (2 mg / kg. The severity of pain at the stages of rehabilitation was assessed using 10-point grading scale (FPS-R. The range of active and passive motions in the joints was evaluated by measuring the range of motions with a fleximeter. Results. Intermittent injection of ropivacaine before rehabilitation allowed to correct post-traumatic elbow contractures in children in the first days after surgery associated with the minimum subjective pain level and stable hemodynamic parameteres, accompanied with a significant increase of the elbow motion range in comparison with the group of the patients who were not performed regional anesthesia . Conclusion. Prolonged blockade of the brachial plexus in rehabilitation treatment of children with post-traumatic contractures provides appropriate analgesic and myoneural block components from the 1st day after intra

Gluteal muscle contracture (GMC) is a chronic fibrotic disease of gluteal muscles which is characterized by excessive deposition of collagen in the extracellular matrix. Transforming growth factor (TGF)-βs have been shown to play an important role in the progression of GMC. However, the underlying mechanisms are not entirely clear. We sought to explore the expression of TGF-β/Smad pathway proteins and their downstream targets in gluteal muscle contracture disease. The expression levels of collagens type I/III, TGF-β1, Smad2/3/4/7 and PAI-1 (plasminogen activator inhibitor type 1) in gluteal muscle contraction (GMC) patients were measured using immunohistochemistry, reverse transcription and polymerase chain reaction (RT-PCR) and western blot assays. The expressions of collagens type I/III and TGF-β1 were significantly increased in the contraction band compared with unaffected muscle. In addition, R-Smad phosphorylation and Smad4 protein expression in the contraction band were also elevated, while the expression of Smad7 was significantly decreased in the fibrotic muscle of the GMC patients compared to the unaffected adjacent muscle. The protein and mRNA levels of PAI-1 were also remarkably increased in the contraction band compared with adjacent muscle. Immunohistochemical analysis also demonstrated that the expression levels of TGF-β1 and PAI-1 were higher in contraction band than those in the adjacent muscle. Our data confirm the stimulating effects of the TGF-β/Smad pathway in gluteal muscle contracture disease and reveal the internal changes of TGF-β/Smad pathway proteins and their corresponding targets in gluteal muscle contracture patients.

Burn scar hand contractures of variable degree are frequently encountered. Although the forearm is apparently spared, it was clinically observed that there was disuse atrophy in the unburnt extrinsic forearm muscles. Usually the clinicians do not give much importance to this fact. The girth at the midforearm was significantly reduced as compared to normal side. The flexion of the hand joints are governed by two components (a) intrinsic and (b) extrinsic muscles. The intrinsic muscles are directly involved in the contracted tissue. Therefore it was thought essential to evaluate the extrinsic group of muscles for their contribution in the final functional recovery following corrective surgery. Thirty patients having unilateral post thermal burn contracture sparing forearm were studied. A detailed clinical evaluation was made including grade of contracture and reduction in the forearm girth. The forearm unburnt muscles were evaluated by preoperative electrophysiological studies. Intraoperative biopsies were taken from these muscles for histopathological examination. On histopathological examination, there were significant abnormal changes in the form of muscle fiber atrophy, fibrolipomatous tissue replacement of atrophic muscle fibers and sarcolemmal changes. These changes were directly proportional to the severity of contractures. The electrophysiological studies showed proportionate changes in the form of reduction in amplitude, duration and interference. This study suggests that if these changes are mild and in reversible stage, they will favourably affect the functional recovery following surgery. However if these changes are of severe grade and irreversible, in spite of adequate surgery, splinting and physiotherapy, the functional recovery may not be complete.

Capsular contracture is a common complication associated with implant-based breast reconstruction and augmentation leading to pain, displacement, and rupture. After capsulectomy and implant exchange, the problem often reappears. We performed 52 deepithelialized free transverse musculocutaneous gracilis (TMG) flaps in 33 patients for tertiary breast reconstruction or augmentation of small- and medium-sized breasts. The indications for implant removal were unnatural feel and emotion of their breasts with foreign body feel, asymmetry, pain, and sensation of cold. Anyway, most of the patients did not have a severe capsular contracture deformity. The TMG flap is formed into a cone shape by bringing the tips of the ellipse together. Depending on the contralateral breast, the muscle can also be shaped in an S-form to get more projection if needed. The operating time for unilateral TMG flap breast reconstruction or augmentation was on average 3 hours and for bilateral procedure 5 hours. One patient had a secondary revision of the donor site due to disruption of the normal gluteal fold. Eighty percent of the unilateral TMG flap reconstructions had a lipofilling procedure afterward to correct small irregularities or asymmetry. The advantages of the TMG flap such as short harvesting time, inconspicuous donor site, and the possibility of having a natural breast shape make it our first choice to treat capsular contracture after breast reconstruction and augmentation.

The use of breast implants for aesthetic and reconstructive purposes has become one of the most common procedures performed by plastic surgeons. Several breast implants models exist. They differ in their size, filling, shape and characteristic of the shell, which can be smooth or textured. Capsular contracture is one of the main complications of breast implants. It has been suggested that the use of textured implants could reduce the incidence of capsular contracture. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified 15 studies overall, of which 13 were randomized trials relevant for the question of interest. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded the use of textured breast implants probably decreases the risk of capsular contracture, however, they might be associated to an increased risk of anaplastic large cell lymphoma.

Full Text Available We report a case of transient osteoporosis of the hip (TOH in a 50-year-old man including the clinical presentation, diagnostic studies, management, and clinical progress. TOH is a rare self-limiting condition that typically affects middle-aged men or, less frequently, women in the third trimester of pregnancy. Affected individuals present clinically with acute hip pain, limping gait, and limited ranges of hip motion. TOH may begin spontaneously or after a minor trauma. Radiographs are typically unremarkable but magnetic resonance (MR imaging studies yield findings consistent with bone marrow edema. TOH is referred to as regional migratory osteoporosis (RMO if it travels to other joints or the contralateral hip. TOH often resembles osteonecrosis but the two conditions must be differentiated due to different prognoses and management approaches. The term TOH is often used interchangeably and synonymously with transient bone marrow edema (TBME.

Danish Hip Arthroscopy Registry (DHAR) was initiated in 2012 as a web-based prospective registry. The purpose of this study was to evaluate and report the epidemiologic and perioperative data of the first 2000 procedures in a Danish hip arthroscopy population and to describe the development of DHAR...... was 0.65 and HAGOS sub-scores were 51 (pain), 49 (symptoms), 53 (ADL), 35 (sport), 20 (physical activity) and 29, respectively. We conclude that patients undergoing hip arthroscopy report considerable pain, loss of function, reduced level of activity and reduced quality-of-life prior to surgery....... The problems with development and maintaining a large clinical registry are described and further studies are needed to validate data completeness. We consider the development of a national clinical registry for hip arthroscopy as a successful way of developing and maintaining a valuable clinical...

Magnetic resonance imaging (MRI) is the modality of choice for evaluation of joint disease. Forty-one hips in 33 patients with osteoarthritis of the hip joint were examined by MRI and the features were analyzed. MR examinations were performed on a 1.5 T superconducting unit using the spin echo (SE) technique with short TR (600 ms)/short TE (23, 28, 35 ms) and short TR (600 ms)/long TE (70, 75 ms) sequences. MRI revealed deformity of the femoral head in all hips. Some outgrowths, which were isointense with normal bone marrow, were shown on the periphery of the femoral head in 22 hips (54%). These outgrowths represented marginal osteophytes. Short TE images showed hypointense areas, which varied in size, in the superior or supero-anterior aspect of the femoral head in all hips, and in the opposite position of the acetabulum in 38 hips (93%). These lesions showed a heterogenous signal with predominant low signal on long TE images. These images may indicate the presence of several components including subchondral cysts, bony sclerosis and fibrous tissue. In the joint space, areas of low signal intensity were shown on short TE images, which were high to intermediate signal intensity on long TE images in 16 hips (39%). These areas were presumably consistent with synovial proliferation, cartilageous hypertrophy or joint effusion. Both MR images revealed a mass locating just anterior to the femoral head in 2 hips (5%). The mass showed a low signal on short TE images and a high signal on long TE images, representing the distended iliopsoas bursa. (author)

Elbow flexion posture, caused by spasticity of the muscles on the anterior surface of the elbow, is the most common elbow deformity seen in patients with cerebral palsy. This study retrospectively evaluated early results of 2 surgical interventions for elbow flexion deformities based on degree of contracture. We hypothesized that by guiding surgical treatment to degree of preoperative contracture, elbow extension and flexion posture angle at ambulation could be improved while preserving maximum flexion. Eighty-six patients (90 elbows) were treated for elbow spasticity due to cerebral palsy. Seventy-one patients (74 elbows) were available for follow-up. Fifty-seven patients with fixed elbow contractures less than 45° were surgically treated with a partial elbow muscle lengthening, which included partial lengthening of the biceps and brachialis and proximal release of the brachioradialis. Fourteen patients (17 elbows) with fixed elbow contractures ≥ 45° had a more extensive full elbow release, with biceps z-lengthening, partial brachialis myotomy, and brachioradialis proximal release. Age at surgery averaged 10 years (range, 3-20 y) for partial lengthening and 14 years (range, 5-20 y) for full elbow release. Follow-up averaged 22 months (range, 7-144 mo) for partial lengthening and 18 months (range, 6-51 mo) for full elbow release. Both groups achieved meaningful improvement in flexion posture angle at ambulation, active and passive extension, and total range of motion. Elbow flexion posture angle at ambulation improved by 57° and active extension increased 17° in the partial lengthening group, with a 4° loss of active flexion. In the full elbow release group, elbow flexion posture angle at ambulation improved 51° and active extension improved 38°, with a loss of 19° of active flexion. Surgical treatment of spastic elbow flexion in cerebral palsy can improve deformity. We obtained excellent results by guiding the surgical intervention by the amount of

Contractures of the knee joint cause disability and handicap. Recovering range of motion is recognized by arthritic patients as their preference for improved health outcome secondary only to pain management. Clinical and experimental studies provide evidence that the posterior knee capsule prevents the knee from achieving full extension. This study was undertaken to investigate the dynamic changes of the joint capsule transcriptome during the progression of knee joint contractures induced by immobilization. We performed a microarray analysis of genes expressed in the posterior knee joint capsule following induction of a flexion contracture by rigidly immobilizing the rat knee joint over a time-course of 16 weeks. Fold changes of expression values were measured and co-expressed genes were identified by clustering based on time-series analysis. Genes associated with immobilization were further analyzed to reveal pathways and biological significance and validated by immunohistochemistry on sagittal sections of knee joints. Changes in expression with a minimum of 1.5 fold changes were dominated by a decrease in expression for 7732 probe sets occurring at week 8 while the expression of 2251 probe sets increased. Clusters of genes with similar profiles of expression included a total of 162 genes displaying at least a 2 fold change compared to week 1. Functional analysis revealed ontology categories corresponding to triglyceride metabolism, extracellular matrix and muscle contraction. The altered expression of selected genes involved in the triglyceride biosynthesis pathway; AGPAT-9, and of the genes P4HB and HSP47, both involved in collagen synthesis, was confirmed by immunohistochemistry. Gene expression in the knee joint capsule was sensitive to joint immobility and provided insights into molecular mechanisms relevant to the pathophysiology of knee flexion contractures. Capsule responses to immobilization was dynamic and characterized by modulation of at least three

Historically, athletic hip injuries have garnered little attention; however, these injuries account for approximately 6% of all sports injuries and their prevalence is increasing. At times, the diagnosis and management of hip injuries can be challenging and elusive for the team physician. Hip injuries are seen in high-level athletes who participate in cutting and pivoting sports that require rapid acceleration and deceleration. Described previously as the "sports hip triad," these injuries consist of adductor strains, osteitis pubis, athletic pubalgia, or core muscle injury, often with underlying range-of-motion limitations secondary to femoroacetabular impingement. These disorders can happen in isolation but frequently occur in combination. To add to the diagnostic challenge, numerous intra-articular disorders and extra-articular soft-tissue restraints about the hip can serve as pain generators, in addition to referred pain from the lumbar spine, bowel, bladder, and reproductive organs. Athletic hip conditions can be debilitating and often require a timely diagnosis to provide appropriate intervention.

Internal urethrotomy (IU) in patients with urethral contracture following perineal repair of pelvic fracture urethral injuries (PRPFUI) is troublesome. We evaluated the clinical factors affecting the surgical outcome of IU for urethral contracture after PRPFUI. We retrospectively reviewed the records of 35 patients who underwent IU for urethral contracture after PRPFUI between March 2004 and June 2013. Ages of patients ranged from 18 to 50, and their follow-up duration was more than 1year after IU. The urethral contracture was confirmed by retrograde urethrogram or cysto-urethroscopy. Success was defined as greater than 15mL/s of peak urinary flow rate at 1year after IU without any clinical evidence of urethral contracture. Success rates were investigated according to the number of IU. Age, body mass index, urethral defect length before PRPFUI, time interval between the original urethral injury and the PRPFUI or between a previous operation and the PRPFUI, time interval between the PRPFUI and the urethral contracture, number of PRPFUI performed, and the type of urethral lengthening procedure were compared between patients with and without success according to the number of IU. Among the 35 patients, the overall success rate of IU was 37% (13/35) during the mean follow-up period of 53 months (range: 17-148 months). There were 8 and 5 patients with success in first and second IU, respectively. However, there was no success after third IU. Urethral defect length before PRPFUI was significantly shorter in patients with success who underwent first and second IU (p<0.05). There were significant differences of success between patients with and without previous repeated failures of PRPFUI in first and second IU (p<0.05). Short urethral defect length and no previous surgical failures before PRPFUI are good prognostic factors for IU following PRPFUI. Only one or two IUs will be helpful in patients with urethral contracture following PRPFUI. Copyright © 2017 Elsevier Ltd

Cervical scar contracture causes both physical and psychological distress for burn patients. Many pedicle flaps or skin grafting have been suggested for reconstruction of cervical scar contracture with variable results in the literature. The authors present the axial thoracic flap based on the thoracic branch of the supraclavicular artery (TBSA) for reconstruction of cervical scar contracture. Postburn scar contractures in anterior neck region of 66 patients had been reconstructed with the axial pattern thoracic flaps based on the TBSA, including 1 expanded and 10 nonexpanded pedicle flaps, and 9 expanded and 46 nonexpanded island pedicle flaps, during 1988 through 2012. After removing and releasing the cervical scar contracture, the flap was designed in the thoracic region. The axial artery of the flap is the TBSA bifurcating from the intersection point of sternocleidomastoid muscle and omohyoid muscle with several concomitant veins as the axial veins. The flap can be designed in a large area within the borders of the anterior border of the trapezius muscle superiorly, the middle part of the deltoid muscle laterally, the midsternal line medially, and the level 3 to 4 cm below nipples inferiorly. After incisions were made along the medial, inferior, and lateral border, dissection was performed toward the pedicle. Donor site was closed directly in expanded cases and with skin grafting in nonexpanded cases. Cervical scar contractures were repaired with good functional and cosmetic results in 64 cases among this cohort. Flap tip necrosis in other 2 cases, caused by postoperative hematoma, was repaired by skin grafting. The color and texture of all flaps were fitted with those of the surrounding skin. The donor sites all healed primarily.

The study aimed to examine the epidemiology of hypertonic contractures and its relationship with minimal trauma fracture (MTF), and to determine the incidence and predictors of (MTF) in long-term care residents. This was a longitudinal cohort study of prospectively collected data. Participants were followed from March 2007 to March 2016 or until death. A 300-bed long-term care hospital in Hong Kong. All long-term care residents who were in need of continuous medical and nursing care for their activities of daily living. Information on patients' demographic data, severe contracture defined as a decrease of 50% or more of the normal passive range of joint movement of the joint, and severe limb spasticity defined by the Modified Ashworth Scale higher than grade 3, medical comorbidities, functional status, cognitive status, nutritional status including body mass index and serum albumin, past history of fractures, were evaluated as potential risk factors for subsequent MTF. Three hundred ninety-six residents [148 males, mean ± standard deviation (SD), age = 79 ± 16 years] were included for analysis. The presence of severe contracture was highly prevalent among the study population: 91% of residents had at least 1 severe contracture, and 41% of residents had severe contractures involving all 4 limbs. Moreover, there were a significant proportion of residents who had severe limb spasticity with the elbow flexors (32.4%) and knee flexors (33.9%) being the most commonly involved muscles. Twelve residents (3%) suffered from subsequent MTF over a median follow-up of 33 (SD = 30) months. Seven out of these 12 residents died during the follow-up period, with a mean survival of 17.8 months (SD = 12.6) after the fracture event. The following 2 factors were found to independently predict subsequent MTF in a multivariate Cox regression: bilateral severe spastic knee contractures (hazard ratio = 16.5, P contractures are common morbidities in long-term care residents

Cerebral palsy (CP) results from an upper motoneuron (UMN)lesion in the developing brain. Secondary to the UMNl esion,which causes spasticity, is a pathological response by muscle - namely, contracture. However, the elements within muscle that increase passive mechanical stiffness, and therefore result in contracture, are unknown. Using hamstring muscle biopsies from pediatric patients with CP (n =33) and control (n =19) patients we investigated passive mechanical properties at the protein, cellular, tissue and architectural levels to identify the elements responsible for contracture. Titin isoform, the major load-bearing protein within muscle cells, was unaltered in CP. Correspondingly, the passive mechanics of individual muscle fibres were not altered. However, CP muscle bundles, which include fibres in their constituent ECM, were stiffer than control bundles. This corresponded to an increase in collagen content of CP muscles measured by hydroxyproline assay and observed using immunohistochemistry. In vivo sarcomere length of CP muscle measured during surgery was significantly longer than that predicted for control muscle. The combination of increased tissue stiffness and increased sarcomere length interact to increase stiffness greatly of the contracture tissue in vivo. These findings provide evidence that contracture formation is not the result of stiffening at the cellular level, but stiffening of the ECM with increased collagen and an increase of in vivo sarcomere length leading to higher passive stresses.

Context: Dance, gymnastics, figure skating, and competitive cheerleading require a high degree of hip range of motion. Athletes who participate in these sports use their hips in a mechanically complex manner. Evidence Acquisition: A search of the entire PubMed database (through December 2013) and additional searches of the reference lists of pertinent articles. Study Design: Systematic review. Level of Evidence: Level 3. Results: Whether innate or acquired, dancers and gymnasts have some hypermobility that allows their hips to be placed in potentially impinging or unstable positions required for their given activity. Such extremes of motion can result in both intra-articular and extra-articular impingement as well as compensatory osseous and muscular pathology. In addition, dancers and gymnasts are susceptible to impingement-induced instability. Dancers with innate generalized hyperlaxity are at increased risk of injury because of their activities and may require longer recovery times to return to play. Both nonoperative and operative treatments (arthroscopic and open) have an important role in returning flexibility athletes to their preoperative levels of sport and dance. Conclusion: Because of the extreme hip motion required and the compensatory soft tissue laxity in dancers and gymnasts, these athletes may develop instability, impingement, or combinations of both. This frequently occurs in the setting of subtle pathoanatomy or in patients with normal bony anatomy. With appropriate surgical indications and the correct operative technique, the treating surgeon can anticipate high levels of return to play for the gymnast and dancer with hip pain. PMID:26137181

Summary Background Recent developments in hip arthroscopic techniques and technology have made it possible in many cases to avoid open surgical dislocation for treating a variety of pathology in the hip. Although early reports suggest favourable results’ using hip arthroscopy and it has been shown to be a relatively safe procedure, complications do exist and can sometimes lead to significant morbidity. Methods This is a review article. The aim of this manuscript is to present the most frequent and/or serious complications that could occur at or following hip arthroscopy and some guidelines to avoid these complications. Conclusion Most complications of hip arthroscopy are minor or transient but serious complications can occur as well. A lot of complication e.g. acetabular labral puncture go unreported. Appropriate education and training, precise and meticulous surgical technique with correct instrumentation, the right indication in the right patient and adherence to advice from mentors and experienced colleagues are all essential factors for a successful outcome.

Full Text Available Background: A 19-year-old female field hockey player presents with bilateral upper trapezius and rhomboid tightness and spasm beginning in January of 2016. She has no previous history of upper back pain or injury. The student first reported the injury immediately after running sprints. She stated that she could not move or feel her fingers or hands. She presents with a visible hump on her left upper trapezius. She also has forward-rounded shoulders. She has regular and equal radial pulses. She has decreased sensation upon palpation of her fingers, hands and forearms. After extraneous exercise, the athlete’s hands, wrists and forearms go into contracture and flexion and she is unable to move from this position until manual extension is applied, or 10 or more minutes of rest occurs. She is TTP over her upper trapezius musculature. She had a positive Military Brace test. Differential Diagnosis: Based on evaluation, the athlete could simply just have upper trapezius musculature spasms. The diagnosis could also be shoulder impingement syndrome, due to the neurological signs and symptoms. Compartment syndrome could produce similar s/s that the athlete experiences, as well. Treatment: X-rays show no bony abnormalities and no extra ribs. The athlete’s injury has been treated with ice post-practice, heat pre-practice and upper body stretching exercises. Three days a week the athlete works on postural exercises that strengthen her back musculature. The athlete also receives combination therapy over her upper trapezius trigger points, along with massage and Hawkgrip technique over the same areas. Uniqueness: The uniqueness in this case is that the athlete has both TOS and Volkmann’s contracture. Volkmann’s contractures typically occur in pediatrics, which is another reason why this particular case is unique. Conclusion: This case allows other clinicians to understand the causes of TOS and the secondary s/s that TOS can potentially cause.

Full Text Available Instillation of intravesical bacillus Calmette-Guérin (BCG is an effective treatment for non-muscle invasive bladder cancer (NMIBC. The high incidence of side effects may limit its tolerability in patients. Local side effects including cystitis and hematuria are common but generally self-limiting. Bladder contractures are a rare but serious consequence of BCG treatment. In this case, an 82 year-old male developed BCG reactivation and subsequent bladder contractures following transurethral resection of the prostate (TURP three years post-BCG. To our knowledge, this is the first reported case of BCG reactivation post-TURP leading to the rare but serious effect of bladder contractures.

The pathophysiology of paradoxical elbow flexion contractures following neonatal brachial plexus injury (NBPI) is incompletely understood. The current study tests the hypothesis that this contracture occurs by denervation-induced impairment of elbow flexor muscle growth. Unilateral forelimb paralysis was created in mice in four neonatal (5-day-old) BPI groups (C5-6 excision, C5-6 neurotomy, C5-6 neurotomy/repair, and C5-T1 global excision), one non-neonatal BPI group (28-day-old C5-6 excision), and two neonatal muscle imbalance groups (triceps tenotomy ± C5-6 excision). Four weeks post-operatively, motor function, elbow range of motion, and biceps/brachialis functional lengths were assessed. Musculocutaneous nerve (MCN) denervation and reinnervation were assessed immunohistochemically. Elbow flexion motor recovery and elbow flexion contractures varied inversely among the neonatal BPI groups. Contracture severity correlated with biceps/brachialis shortening and MCN denervation (relative axon loss), with no contractures occurring in mice with MCN reinnervation (presence of growth cones). No contractures or biceps/brachialis shortening occurred following non-neonatal BPI, regardless of denervation or reinnervation. Neonatal triceps tenotomy did not cause contractures or biceps/brachialis shortening, nor did it worsen those following neonatal C5-6 excision. Denervation-induced functional shortening of elbow flexor muscles leads to variable elbow flexion contractures depending on the degree, permanence, and timing of denervation, independent of muscle imbalance.

To diagnose malignant hyperthermia susceptibility (MHS), caffeine and halothane contracture tests were performed on six patients. One of them, who presented a peroperative crisis, was recognized as MHS; the five others were negative (MHN). By means of 31P-NMR spectroscopy, the muscular energetic metabolism of these patients was studied during and after moderate exercise in normal and moderate ischaemic conditions. Metabolic abnormalities appeared in the MHS patient. It must be concluded therefore that malignant hyperthermia is a latent myopathy. 31P-NMR spectroscopy appeared to be a useful non-invasive tool for screening for this affliction.

Spastic paretic hemifacial contracture (SPHC) is characterized by sustained unilateral contraction of the facial muscles associated with mild ipsilateral facial paresis. Rarely described in the context of multiple sclerosis (MS), it has never been reported as presenting symptom of MS. Two patients developed SPHC within the context of a clinically isolated syndrome suggestive of MS. EMG revealed continuous resting activity of irregularly firing motor unit potentials, associated with impaired recruitment upon voluntary contraction. SPHC remitted fully in both patients. SPHC, a rare but distinct clinical and EMG entity, can occasionally be the presenting feature of MS. Copyright © 2017 Elsevier B.V. All rights reserved.

Severe knee contractures that develop soon after muscle imbalance may not improve with stretching exercises and splinting. An alternative treatment is serial casting, which has been used to promote increased range of motion. The purpose of this study was to compare the effectiveness of using serial casting and passive stretching approaches to treat knee flexion contracture in children with spina bifida. In a pre/post randomized controlled study, ten participants were included in the serial casting group, while eight participants were included in the passive stretching intervention group. The degree of knee extension was measured at baseline, immediately after intervention, and at a one-year follow-up using a standard goniometer. Both groups showed significant improvements in the degree of flexion contracture at the post-treatment evaluation and the follow-up evaluation. The serial casting group showed significant improvements in knee flexion contracture at the post-treatment evaluation, t (9)=13.4, p casting group compared with passive stretching group in relation to the degree of flexion contracture were found at the immediate post-treatment evaluation, F(1, 15)=246, p=0.0001, and the one-year follow-up evaluation, F (1, 15)=51.5, p=0.0001. The outcomes of this study provide the first evidence that serial casting may be a useful intervention in treating knee flexion contracture in children with spina bifida. However, further investigations into serial casting, as well as investigations into the use of serial casting with other interventions, are warranted.
Full Text Available Emery-Dreifuss muscular dystrophy (EDMD is a hereditary neuromuscular disorder characterized by slowly progressive muscle weakness, early contractures, and dilated cardiomyopathy. We reported an uneventful general anaesthesia using total intravenous anaesthesia (TIVA for cardiac transplantation in a 19-year-old woman suffering from EDMD. In vitro contracture test results of two pectoralis major muscle bundles of the patient suggest that exposition to triggering agents does not induce a pathological sarcoplasmic calcium release in the lamin A/C phenotype. However, due to the lack of evidence in the literature, we would recommend TIVA for patients with EDMD if general anaesthesia is required.

Objective: To elucidate the relationship between gluteal muscle contracture (GMC) and the iliac hyperdense line on pelvic plain film, and to explore how the iliac hyperdense line is formed. Methods: The pelvic plain films of 103 cases with GMC confirmed by operation and those of 200 individuals as control were analyzed. Pelvic CT scanning was performed in 8 cases GMC and 13 cases of normal controls. Results: The iliac hyperdense line at the side of sacroiliac joint was found on the pelvic plain film in 85 of 103 cases with GMC and 5 of 200 in control group. In 103 cases of GMC, the iliac hyperdense line was detected in 81 of 88 patients beyond 5 years, and 83 of 94 was mostly the gluteus maximus contracture. In control group, pelvic CT showed that the outer cortex of posterior ilium at the level of sacroiliac joint appeared as an oblique plane, oriented from posteromedial side to anterolateral side, while in GMC group, the oblique plane became steeper and almost oriented posteroanteriorly. In addition, the posterior part of the ilium which gave the attachment of contracted gluteus maximus muscle deformed and widened. Conclusion: The iliac hyperdense line on the pelvic plain film is resulted from the long and persistent pulling effect of contracted gluteus maximus muscle, which causes the change the oblique plane of posterior ilium into a posteroanterior course parallel to the X-ray beam

Muscle pathology of the arm and forearm in brachial plexus birth injury (BPBI) with elbow flexion contracture has not been evaluated with MRI. To determine whether limited range of motion of the elbow in BPBI is correlated with specific patterns of muscular pathology. For 15 BPBI patients, total active motion (TAM) of the elbow (extension-flexion) and the forearm (pronation-supination) were measured. MRI of the elbow joints and musculature allowed assessment of elbow congruency. Fatty infiltration and size reduction of the muscles were graded semiquantitatively. Mean TAM of the elbow was 113 (50 -140 ) and that of the forearm 91 (10 -165 ). The greater the size reduction of the brachioradialis muscle, the more diminished was elbow TAM. The more extensive the BPBI and muscle pathology of the pronator teres muscle, the more limited was the TAM of the forearm. Pathology of the supinator and brachialis muscles was evident in every patient. Extensive BPBI may result in marked limitation of TAM. Elbow flexion contracture seems to be caused mainly by brachialis muscle pathology. Prosupination of the forearm is better preserved when the pronator teres is not severely affected. MRI can reliably show the extent of muscle pathology in BPBI. (orig.)

Dupuytren's disease is a slowly progressive condition of the hand, characterised by the formation of nodules in the palm that gradually develop into fibrotic cords. Contracture of the cords produces deformities of the fingers. Surgery is recommended for moderate and severe contractures, but complications and/or recurrences are frequent. Collagenase clostridium histolyticum (CCH) has been developed as a minimally invasive alternative to surgery for some patients. To assess the clinical effectiveness and cost-effectiveness of collagenase as an alternative to surgery for adults with Dupuytren's contracture with a palpable cord. We searched all major electronic databases from 1990 to February 2014. Randomised controlled trials (RCTs), non-randomised comparative studies and observational studies involving collagenase and/or surgical interventions were considered. Two reviewers independently extracted data and assessed risk of bias of included studies. A de novo Markov model was developed to assess cost-effectiveness of collagenase, percutaneous needle fasciotomy (PNF) and limited fasciectomy (LF). Results were reported as incremental cost per quality-adjusted life-year (QALY) gained. Deterministic and probabilistic sensitivity analyses were undertaken to investigate model and parameter uncertainty. Five RCTs comparing collagenase with placebo (493 participants), three RCTs comparing surgical techniques (334 participants), two non-randomised studies comparing collagenase and surgery (105 participants), five non-randomised comparative studies assessing various surgical procedures (3571 participants) and 15 collagenase case series (3154 participants) were included. Meta-analyses of RCTs assessing CCH versus placebo were performed. Joints randomised to collagenase were more likely to achieve clinical success. Collagenase-treated participants experienced significant reduction in contracture and an increased range of motion compared with placebo-treated participants

Conclusions: When used to treat joint scar contractures, the square flap method can fully span the web space in a stereometric manner, thus yielding a close-to-original shape and function. Compared with the classical Z-plasties, it also provides sufficient anatomical blood supply while imposing the least physiological tension on the adjacent skin.

Full Text Available Introduction Dupuytren's contracture is a disease of connective tissue with the affection of palmar aponeurosis, frequently with chronic recurrent course, the flexion deformities of fingers and dysfunction of the hand. It composed 11,8 % among of all types of the hand pathology. The mostly it develops in men of middle-aged and elderly. At young age it occurs more rarely, but with fast progressing current, which in 67 % of cases leads to impaired ability to perform professional hand-work and in 3 % patients to physical inability. Predisposing factors for this fibromatosis are numerous, but one of the popular opinion among of authors is a hereditary character of disease. In clinical practice, the most frequently used fourth degree’s classification of Dupuytren's contracture includes severity of deformation and function disorders of the hand. It is correspond to the normative standards of medical and social expertise The aim of research: to specify the most optimal methods of surgical treatment, the criteria of medical and social examination and rehabilitation, clinical and labor prognosis, indications to establishment of disability after operations concerning of Dupuytren’s contracture. In our clinic was performed three methods of operation: aponeurotomia “open hand”, partial aponeuroectomia, total aponeuroectomia. Errors in the treatment of palmar fibromatosis we shared on: preoperated, intraoperated and associated with violations of the mode of rehabilitation. The next clinical observation of 68 patients (up to 3 years after surgery with Dupuytren’s contracture of hand showed the recurrence rate amounted to 31,7%, and physical inability level is 5,9% of cases. In our opinion the most optimal operative methodic is total aponeuroectomia with rational surgical approaches. Clinical and labour prognosis depends on the manifestations of disease which can develop regardless of the stage, methods of treatment and patient's age. Disadvantageous

Patients with hip osteoarthritis often have an abnormal spine-hip relation (SHR), meaning the presence of a clinically deleterious spine-hip and/or hip-spine syndrome. Definition of the individual SHR is ideally done using the EOS® imaging system or, if not available, with conventional lumbopelvic lateral radiographs. By pre-operatively screening patients with abnormal SHR, it is possible to refine total hip replacement (THR) surgical planning, which may improve outcomes. An important component of the concept of kinematically aligned total hip arthroplasty (KA THA) consists of defining the optimal acetabular cup design and orientation based on the assessment of an individual’s SHR, and use of the transverse acetabular ligament to adjust the cup positioning. The Bordeaux classification might advance the understanding of SHR and hopefully help improve THR outcomes. Cite this article: EFORT Open Rev 2018;3:39-44.

Post-mastectomy breast reconstruction with expanders and implants is recognized as an integral part of breast cancer treatment. Its main complication is represented by capsular contracture, which leads to poor expansion, breast deformation, and pain, often requiring additional surgery. In such a scenario, the debate continues as to whether the second stage of breast reconstruction should be performed before or after post-mastectomy radiation therapy, in light of potential alterations induced by irradiation to silicone biomaterial. This work provides a novel, multi-technique approach to unveil the role of radiotherapy in biomaterial alterations, with potential involvement in capsular contracture. Following irradiation, implant shells underwent mechanical, chemical, and microstructural evaluation by means of tensile testing, Attenuated Total Reflectance Fourier Transform InfraRed spectroscopy (ATR/FTIR), Scanning Electron Microscopy (SEM), high resolution stylus profilometry, and Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS). Our findings are consistent with radiation-induced modifications of silicone that, although not detectable at the microscale, can be evidenced by more sophisticated nanoscale surface analyses. In light of these results, biomaterial irradiation cannot be ruled out as one of the possible co-factors underlying capsular contracture. - Highlights: • The debate continues whether to perform breast reconstruction before or after PMRT. • Radiation therapy may alter implant material, concurring to capsular contracture. • In this work, irradiated implants were investigated by a multi-technique approach. • Radiation-induced alterations could be evidenced by ATR/FTIR and ToF-SIMS. • Reported alteration might represent a co-factor underlying capsular contracture.

To analyze and report the clinical outcomes of a cohort of patients who underwent revision hip preservation with arthroscopy and determine predictors of positive and negative outcomes. During the study period from April 2008 to December 2010, all patients who underwent revision hip preservation with arthroscopy were included. This included patients who had previous open surgery and underwent revision with arthroscopy. Patient-reported outcome (PRO) scores were obtained preoperatively and at 3-month, 1-year, 2-year, and 3-year follow-up time points. Any revision surgeries and conversions to total hip arthroplasty were noted. A multiple regression analysis was performed to look for positive and negative predictive factors for improvement in PROs after revision hip arthroscopy. Forty-seven hips in 43 patients had completed 2 years' follow-up or needed total hip arthroplasty. The mean length of follow-up was 29 months (range, 24 to 47 months). Of the hips, 31 (66%) had either unaddressed or incompletely treated femoroacetabular impingement. There was a significant improvement in all PRO scores at a mean of 29 months after revision (P arthroscopy can achieve moderately successful outcomes and remains a viable treatment strategy after failed primary hip preservation surgery. Preoperative predictors of success after revision hip arthroscopy include segmental labral defects, unaddressed or incompletely addressed femoroacetabular impingement, heterotopic ossification, and previous open surgery.

Injury of the medial head of the gastrocnemius, also called "tennis leg," is known to heal uneventfully in most cases with compression and immobilization therapy. Failure to heal or long-term complications, including ongoing pain and pes equinus, have been documented in only a limited number of case reports. To the best of our knowledge, a severe concomitant contracture of the knee and ankle joint as a consequence of a maltreated gastrocnemius muscle rupture has not been previously reported in English-language reports. The purpose of the present study was to report a serious complication of neglected tennis leg with a review of the published data. Copyright © 2016 American College of Foot and Ankle Surgeons.

Satellite cells (SC) are quiescent adult muscle stem cells critical for postnatal development. Children with cerebral palsy have impaired muscular growth and develop contractures. While flow cytometry previously demonstrated a reduced SC population, extracellular matrix abnormalities may influence the cell isolation methods used, systematically isolating fewer cells from CP muscle and creating a biased result. Consequently, the purpose of this study was to use immunohistochemistry on serial muscle sections to quantify SC in situ. Serial cross-sections from human gracilis muscle biopsies (n = 11) were labeled with fluorescent antibodies for Pax7 (SC transcriptional marker), laminin (basal lamina), and 4',6-diamidino-2-phenylindole (nuclei). Fluorescence microscopy under high magnification was used to identify SC based on labeling and location. Mean SC/100 myofibers was reduced by ∼70% (p muscle growth and apparent decreased responsiveness of CP muscle to exercise. © 2015 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Social inequality appears to be increasing in many countries. We explored whether risk of hip fracture was associated with markers of inequality and whether these relationships changed with time, using data from Danish Health Registries. Methods: All patients 60 years or older with a primary hip...... fracture (ICD10: S720, S721, S722 and S729) were identified from 1 January 1995 to 31 December 2011. Hip fracture patients were matched 1:1 on age, gender and year of fracture to a non-hip fracture control. An individual's education attainment was defined as basic, secondary or higher, and their income...

Dupuytren's disease is one of the fibro-proliferative conditions affecting the palmar and digital fascia. This disease has been known to surgeons and treated by them for at least 200 years. Dupuytren's disease is very common in Northern Europe and also in countries inhabited by immigrants from Northern Europe. Dupuytren's contracture is stated to be uncommon in Indian subcontinent and very little has been written about this disease in India. The authors have however come across 30 patients with Dupuytren's contracture and they are the subject of this paper, with special emphasis on its surgical correction and complications of surgical treatment. Patients were categorized into stages I, II and III as per the severity of disease. Regional fasciectomy was performed in 90% of the patients and extensive fasciectomy in 10% of patients. Most of wounds were closed by primary closure with z-plasty. In rest of the patients free skin grafts were used to close the wound, when primary closure was not possible. The patients were followed up regularly for 5 years and the results of surgical treatment were categorized into excellent, good, fair and poor. The results were excellent in 23 patients (76.66%), good in six patients (20%) and fair in one patient (3.33%). Post operative edema and some stiffness was seen in two patients. Wound infection was seen in one patient and haematoma in one patient. The correct surgical technique and meticulous post operative care is needed to achieve higher rates of correction and to limit the complications and recurrence.

Cerebral palsy (CP) is an upper motor neuron disease that results in a spectrum of movement disorders. Secondary to the neurological lesion, muscles from patients with CP are often spastic and form debilitating contractures that limit range of motion and joint function. With no genetic component, the pathology of skeletal muscle in CP is a response to aberrant complex neurological input in ways that are not fully understood. This study was designed to gain further understanding of the skeletal muscle response in CP using transcriptional profiling correlated with functional measures to broadly investigate muscle adaptations leading to mechanical deficits.Biopsies were obtained from both the gracilis and semitendinosus muscles from a cohort of patients with CP (n = 10) and typically developing patients (n = 10) undergoing surgery. Biopsies were obtained to define the unique expression profile of the contractures and passive mechanical testing was conducted to determine stiffness values in previously published work. Affymetrix HG-U133A 2.0 chips (n = 40) generated expression data, which was validated for selected transcripts using quantitative real-time PCR. Chips were clustered based on their expression and those from patients with CP clustered separately. Significant genes were determined conservatively based on the overlap of three summarization algorithms (n = 1,398). Significantly altered genes were analyzed for over-representation among gene ontologies and muscle specific networks.The majority of altered transcripts were related to increased extracellular matrix expression in CP and a decrease in metabolism and ubiquitin ligase activity. The increase in extracellular matrix products was correlated with mechanical measures demonstrating the importance in disability. These data lay a framework for further studies and development of novel therapies.

Full Text Available Malignant hyperthermia (MH is a pharmacogenetic disease triggered by volatile anesthetics and succinylcholine. Deaths due to MH have been reported in Brazil. The first Malignant Hyperthermia Diagnostic and Research Center in Latin America was inaugurated in 1993 at the Federal University of Rio de Janeiro, Brazil. The center followed the diagnostic protocols of the North America MH Group, in which the contractures of biopsies from the vastus lateralis muscle are analyzed after exposure to caffeine and halothane (CHCT. CHCT was performed in individuals who survived, their relatives and those with signs/symptoms somewhat related to MH susceptibility (MHS. Here, we report data from 194 patients collected over 16 years. The Southeast (N = 110 and South (N = 71 represented the majority of patients. Median age was 25 (4-70 years, with similar numbers of males (104 and females (90. MHS was found in 90 patients and 104 patients were normal. Abnormal responses to both caffeine and halothane were observed in 59 patients and to caffeine or halothane in 20 and 11 patients, respectively. The contracture of biopsies from MHS exposed to caffeine and halothane was 1.027 ± 0.075 g (N = 285 and 4.021 ± 0.255 g (N = 226, respectively. MHS was found in patients with either low or high blood creatine kinase and also, with a low score on the clinical grading scale. Thus, these parameters cannot be used with certainty to predict MHS. We conclude that the CHCT protocol described by the North America MH Group contributed to identification of MHS in suspected individuals at an MH center in Brazil with 100% sensitivity and 65.7% specificity.

Background and Purpose: In early-stage Dupuytren's contracture, radiotherapy is applied to prevent disease progression. Long-term outcome and late toxicity of the treatment were evaluated in a retrospective analysis. Patients and Methods: Between 12/1982 and 02/2006, 135 patients (208 hands) were irradiated with orthovoltage (120 kV; 20 mA; 4-mm Al filter), in two courses with five daily fractions of 3.0 Gy to a total dose of 30 Gy; separated by a 6- to 8-week interval. The extent of disease was described according to a modified classification of Tubiana et al. Long-term outcome was analyzed at last follow-up between 02/2008 and 05/2008 with a median follow-up of 13 years (range, 2-25 years). Late treatment toxicity and objective reduction of symptoms as change in stage and numbers of nodules and cords were evaluated and used as evidence to assess treatment response. Results: According to the individual stages, 123 cases (59%) remained stable, 20 (10%) improved, and 65 (31%) progressed. In stage N 87% and in stage N/I 70% remained stable or even regressed. In more advanced stages, the rate of disease progression increased to 62% (stage I) or 86% (stage II). 66% of the patients showed a long-term relief of symptoms (i.e., burning sensations, itching and scratching, pressure and tension). Radiotherapy did not increase the complication rate after surgery in case of disease progression and only minor late toxicity (skin atrophy, dry desquamation) could be observed in 32% of the patients. There was no evidence for a second malignancy induced by radiotherapy. Conclusion: After a mean follow-up of 13 years radiotherapy is effective in prevention of disease progression and improves patients' symptoms in early-stage Dupuytren's contracture (stage N, N/I). In case of disease progression after radiotherapy, a ''salvage'' operation is still feasible. (orig.)
Full Text Available Objectives: Head and neck cancer patients who have lost facial parts following surgical intervention frequently require craniofacial implant retained facial prostheses for restoration. Many craniofacial implant patients require computed tomography and magnetic resonance imaging scans as part of their long-term follow-up care. Consequently removal of implant superstructures and peri-abutment tissue management is required for those studies. The purpose of the present paper was to describe a method for eliminating cranial imaging artifacts in patients with craniofacial implants.Material and Methods: Three patients wearing extraoral implant retained facial prostheses needing either computed tomography or magnetic resonance imaging studies were discussed. Peri-implant soft tissues contracture after removal of percutaneous craniofacial implant abutments during computed tomography and magnetic resonance imaging studies was prevented using a method proposed by authors. The procedure involves temporary removal of the supra-implant components prior to imaging and filling of the tissue openings with polyvinyl siloxane dental impression material.Results: Immediately after filling of the tissue openings with polyvinyl siloxane dental impression material patients were sent for the imaging studies, and were asked to return for removal of the silicone plugs and reconnection of all superstructure hardware after imaging procedures were complete. The silicone plugs were easily removed with a dental explorer. The percutaneous abutments were immediately replaced and screwed into the implants which were at the bone level.Conclusions: Presented herein method eliminates the source of artifacts and prevents contracture of percutaneous tissues upon removal of the implant abutments during imaging.

Gluteal tendinopathy (GT) and hip osteoarthritis (OA) are the most common causes of hip pain and associated disability in older adults. Pain and altered walking biomechanics are common to both conditions. This study aimed to compare three-dimensional walking biomechanics between individuals with unilateral, symptomatic GT and HOA. Sixty individuals with symptomatic unilateral GT confirmed by magnetic-resonance-imaging and 73 individuals with symptomatic unilateral HOA (Kellgren-Lawrence Grade ≥ 2) underwent three-dimensional gait analysis. Maximum and minimum values of the external sagittal hip moment, the first peak, second peak and mid-stance minimum of the hip adduction moment (HAM), sagittal plane hip excursion and hip joint angles, pelvic obliquity and trunk lean, at the three HAM time points during stance phase of walking were compared between groups. Compared to individuals with HOA, those with GT exhibited a greater hip peak extension moment (P < 0.001) and greater HAM throughout the stance phase of walking (P = 0.01-P < 0.001), greater hip adduction (P < 0.001) and internal rotation (P < 0.01-P < 0.001) angles and lower hip flexion angles and excursion (P = 0.02 - P < 0.001). Individuals with HOA exhibited a greater forward trunk lean (P ≤ 0.001) throughout stance, and greater ipsilateral trunk lean in the frontal plane (P < 0.001) than those with GT. Despite presence of pain in both conditions, hip kinematics and kinetics differ between individuals with symptomatic unilateral GT and those with symptomatic unilateral HOA. These condition-specific impairments may be targets for optimization of management of HOA and GT. Copyright © 2018 Elsevier B.V. All rights reserved.
of them are non-ambulators and 38 (95,0% were classified as GFMCS V and 2 (5,0% were level IV. The patients were divided in two groups (with or without indications for hip surgical treatment. The hips were analysed by Thomas, abduction, and Nelaton-Galeazzi tests. The scoliosis was clinically analysed considering trunk symmetry and dorsal hump. Results: We observed positive correlation between the patients’ scoliosis and hip flexion contracture. There was no difference between the patients’ age and and hip flexion contracture. There was no difference between topographic types and hip contractures. Conclusions: We did not find positive correlation between patients’ age and hip contractures; patients with scoliosis present worse hip abduction compromise.

The authors report the data relative to 1507 cases studied with clinical and US examinations, in the neonatal period, in order to exclude hip dysplasia dislocation. US examination was carried out according to Graf's technique and the newborns were classified according to US hip type, to clinical examination and to possible risk factors. The patients were included in a protocol including orthopedic and US controls. Seventeen treated infants were considered as pathologic. Ten of them had IIc or D hips ar birth; the other 7, with IIa hips at birth, presented a X-ray pathologic hip after the 4th months of life. At about one year of age all infants could normally walk, excpet for one who was being treated with herness. No statistically significant differences were observed between the number of pathologic infants in the risk group (1.7%) and that in the no-risk group (0.8%). Clinical examination of the newborn has low sensitivity in detecting pathologic hips. On the basis of their results, thw authors belive US examination of the newborn to be a valuable screening method to diagnose hip dysplasia/dislocation. Moreover, Graf's morphologic method is the best one for US screening of the hip in the neonatal period

In Canada, Dupuytren's contracture is managed with partial fasciectomy or percutaneous needle aponeurotomy (PNA). Injectable collagenase will soon be available. The optimal management of Dupuytren's contracture is controversial and trade-offs exist between the different methods. Using a cost-utility analysis approach, our aim was to identify the most cost-effective form of treatment for managing Dupuytren's contracture it and the threshold at which collagenase is cost-effective. We developed an expected-value decision analysis model for Dupuytren's contracture affecting a single finger, comparing the cost-effectiveness of fasciectomy, aponeurotomy and collagenase from a societal perspective. Cost-effectiveness, one-way sensitivity and variability analyses were performed using standard thresholds for cost effective treatment ($50 000 to $100 000/QALY gained). Percutaneous needle aponeurotomy was the preferred strategy for managing contractures affecting a single finger. The cost-effectiveness of primary aponeurotomy improved when repeated to treat recurrence. Fasciectomy was not cost-effective. Collagenase was cost-effective relative to and preferred over aponeurotomy at $875 and $470 per course of treatment, respectively. In summary, our model supports the trend towards non-surgical interventions for managing Dupuytren's contracture affecting a single finger. Injectable collagenase will only be feasible in our publicly funded healthcare system if it costs significantly less than current United States pricing.

Using area under the contracture curve to quantitate contractures, the diffusion coefficient of calcium ions within the frog toe muscle during washout in a calcium-free solution and subsequent recovery after reintroduction of calcium to the bathing solution was calculated to be about 2 x 10-6 cm2/sec. The diffusion coefficient measured during washout was found to be independent of temperature or initial calcium ion concentration. During recovery it was found to decrease if the temperature was lowered. This was likely due to the repolarization occurring after the depolarizing effect of the calcium-free solution. The relation between contracture area and [Ca]o was found to be useful over a wider range than that between maximum tension and [Ca]o. The normalized contracture areas were larger at lower calcium concentrations if the contractures were produced with cold potassium solutions or if NO3 replaced Cl in the bathing solutions. Decreasing the potassium concentration of the contracture solution to 50 mM from 115 mM did not change the relation between [Ca]o and the normalized area. If the K concentration of the bathing solution was increased, the areas were decreased at lower concentrations of Ca. PMID:14324991

In unilateral congenital superior oblique palsy, a large hypertropia is sometimes associated with ipsilateral contracture of the superior rectus muscle and apparent overaction of the contralateral superior oblique. Ipsilateral double elevator weakening is one surgical approach; however, this procedure could compromise supraduction. We report a series of three consecutive patients who underwent ipsilateral superior rectus and inferior oblique recessions for unilateral superior oblique palsy. Intraoperatively, all three patients were found to have a lax ipsilateral superior oblique tendon. Postoperatively, all three patients had satisfactory correction of the hypertropia and abnormal head position with minimal supraduction defect. This procedure seems to be an acceptable initial surgical option for treating congenital superior oblique muscle palsy with ipsilateral contracture of the superior rectus muscle, even when the ipsilateral superior oblique tendon is lax.

To discuss the effectiveness of distal palm perforator mini-flap in the treatment of scar contracture of digital web-spaces. Between August 2008 and March 2010, 6 cases of scar contracture of digital web-spaces were treated, including 4 males and 2 females and aging 16-68 years (mean, 45 years). The causes were burn injury, twisting injury, and crush injury in 2 cases, respectively. The disease duration was from 3 months to 3 years. The affected digital web-spaces were from index finger to middle finger in 2 cases, from middle finger to ring finger in 3 cases, and from ring finger to small finger in 1 case. The maximum abduction degree of digital web-spaces was 5-10 degrees. The sizes and the depths of reshape of digital web-spaces disappeared. The defect size ranged from 20 mm x 8 mm to 30 mm x 13 mm after opening digital web-spaces. The size of the distal palm perforator mini-flap ranged from 25 mm x 10 mm to 35 mm x 15 mm. The donor sites were sutured directly. All 6 flaps survived and got primary healing. Incisions at donor sites healed by first intention. All patients were followed up 6-12 months. The reconstructed digital web-spaces had good appearance and soft texture. The range of motion of metacarpophalangeal joint was normal. The sizes and the depths of reshape of digital web-spaces were similar to normal ones. The maximum abduction degree of digital web-spaces was 40-60 degrees. There was no scar contracture of incision of palm. The shape of flaps and function of the fingers were satisfactory after 6-12 months of follow-up. It is an ideal method to treat scar contracture of digital web-spaces with distal palm perforator mini-flap.

Limb girdle muscular dystrophy 2A is a common variant secondary to mutations in the calpain 3 gene. A proportion of patients has early and severe contractures, which can cause diagnostic difficulties with other conditions. We report clinical and muscle magnetic resonance imaging findings in seven limb girdle muscular dystrophy 2A patients (four sporadic and three familial) who had prominent and early contractures. All patients showed a striking involvement of the posterior thigh muscles. The involvement of the other thigh muscles was variable and was related to clinical severity. Young patients with minimal functional motor impairment showed a predominant involvement of the adductors and semimembranosus muscles while patients with restricted ambulation had a more diffuse involvement of the posterolateral muscles of the thigh and of the vastus intermedius with relative sparing of the vastus lateralis, sartorius and gracilis. At calf level all patients showed involvement of the soleus muscle and of the medial head of the gastrocnemius with relative sparing of the lateral head. MRI findings were correlated to those found in two patients with the phenotype of limb girdle muscular dystrophy 2A without early contractures and the pattern observed was quite similar. However, the pattern observed in limb girdle muscular dystrophy 2A is different from that reported in other muscle diseases such as Emery-Dreifuss muscular dystrophy and Bethlem myopathy which have a significant clinical overlap with limb girdle muscular dystrophy 2A once early contractures are present. Our results suggest that muscle MRI may help in recognising patients with limb girdle muscular dystrophy 2A even when the clinical presentation overlaps with other conditions, and may therefore, be used as an additional investigation to target the appropriate biochemical and genetic tests.

Congenital contractural arachnodactyly (Beals syndrome) is a rare autosomal dominantly inherited connective tissue disorder characterized by flexion contractures, arachnodactyly, crumpled ears, and mild muscular hypoplasia. Here, a father and son with congenital contractural arachnodactyly features were identified. After sequencing 15 exons (22 to 36) of the FBN2 gene, a novel mutation (C1425Y) was found in exon 33. This de novo mutation presented first in the father and was transmitted to his son, but not in the other 14 unaffected family members and 365 normal people. The C1425Y mutation occurs at the 19th cbEGF domain. Cysteines in this cbEGF domain are rather conserved in species, from human down to ascidian. The cbEGF12-13 in human FBN1 was employed as the template to perform homology modeling of cbEGF18-19 of human FBN2 protein. The mutation has also been evaluated by further prediction tools, for example, SIFT, Blosum62, biochemical Yu's matrice, and UMD-Predictor tool. In all analysis, the mutation is predicted to be pathogenic. Thus, the structure destabilization by C1425Y might be the cause of the disorder.

A 68-year-old man, with a history of type 2 diabetes mellitus and chronic kidney impairment, had been suffering from progressive knee joint contracture and dysesthesia of the lower extremities for 4 years. When he walked, his knees remained bent owing to contracture of the knee joints. There was no evidence of muscle pseudohypertrophy, intramuscular nodules, or muscle weakness. Clinical examination revealed IgA λ M-protein, reticular high-signal intensity lesions demonstrated by magnetic resonance T2-short TI IR(STIR) imaging of the lower extremity muscles, and a mixture of neurogenic and myogenic changes demonstrated by needle electromyography. A biopsy specimen from the vastus lateralis muscle identified Aλ amyloid deposits around the vessels, establishing a diagnosis of amyloid myopathy based on systemic AL amyloidosis. This case demonstrated that joint contracture and reticular lesions shown by magnetic resonance STIR imaging of the muscles can alert the physician to consider muscle biopsy to investigate deposition of amyloid in the skeletal muscles even in the absence of muscle pseudohypertrophy or weakness, both of which are characteristic of amyloid myopathy.

The goal of this study was to determine whether intra-articular administration of the potentially anti-fibrotic agent decorin influences the expression of genes involved in the fibrotic cascade, and ultimately leads to less contracture, in an animal model. A total of 18 rabbits underwent an operation on their right knees to form contractures. Six limbs in group 1 received four intra-articular injections of decorin; six limbs in group 2 received four intra-articular injections of bovine serum albumin (BSA) over eight days; six limbs in group 3 received no injections. The contracted limbs of rabbits in group 1 were biomechanically and genetically compared with the contracted limbs of rabbits in groups 2 and 3, with the use of a calibrated joint measuring device and custom microarray, respectively. There was no statistical difference in the flexion contracture angles between those limbs that received intra-articular decorin versus those that received intra-articular BSA (66° vs 69°; p = 0.41). Likewise, there was no statistical difference between those limbs that received intra-articular decorin versus those who had no injection (66° vs 72°; p = 0.27). When compared with BSA, decorin led to a statistically significant increase in the mRNA expression of 12 genes (p Cite this article: Bone Joint Res 2014;3:82-8.

Radiographic evaluation of joint replacements requires close communication between the radiologist and referring physician. Routine films, radioisotope scans, and subtraction arthrography (including aspiration and injection of the pseudocapsule) may be indicated in different clinical situations. This paper summarizes the accuracy of these modalities. Most patients present with pain. One must exclude loosening, infection, and other problems. The arthrogram is most useful in defining anatomy and most causes of hip pain. Culture studies and diagnostic injections add to the versatility of subtraction arthrography and increase its accuracy. If plain films are negative, a Tc-99m scan can be obtained. If this is negative, loosening is unlikely. If pain persists or if the scan is positive, an arthrogram should be performed. Pain may be secondary to bursitis rather than loosening, and the arthrogram will assist in diagnosis and treatment. When films suggest loosening, arthrography is the procedure of choice to confirm the diagnosis and to exclude infection

Chemoradiotherapy protocols are a recent development in the management of tumours where preservation of organ function is important. It is now recognized that such combined treatment may produce adverse effects below the accepted dose thresholds for either modality. This enhancement of toxicity is generally thought to reflect depletion of stem cells within the tissue concerned. We report four patients who have developed avascular necrosis or fractures of the hip following chemoradiotherapy for carcinoma of the vulva or anus. These complications developed after a radiation dose of 4500 cGy in 20 fractions. The possible role of cytotoxic agents in sensitizing bone to radiation damage is discussed, and a novel mechanism is proposed to account for this phenomenon. (author).

Traumatic lesions of the hip in athletes may be clinically challenging because of the overlap in clinical presentation due to differing pathologies and the presence of multiple injuries. Imaging of the hip in the athlete has undergone a recent resurgence of interest and understanding related to the increasing accessibility and use of hip arthroscopy, which expands the treatment options available for intra-articular pathology. MR imaging and MR arthrography have a unique role in diagnosis of these pathologies, guiding the surgeon, arthroscopist, and referring clinician in their management of bony and soft tissue injury.

Multiple factors regarding surgical procedures and patient selection affect hospital staffing needs as well as hospital revenues. In order to better understand the potential impact on hospitals that hip arthroplasty device selection (standard total hip arthroplasty vs. resurfacing) creates, a review of all primary hip arthroplasties performed at one institution was designed to identify factors that impacted hospital staffing needs and revenue generation. All primary hip arthroplasties undertaken over three fiscal years (2008 to 2010) were reviewed, utilizing only hospital business office data and medical records data that had been previously extracted prior for billing purposes. Analysis confirmed differing demographics for two hip arthroplasty populations, with the resurfacing patients (compared to the conventional total hip arthroplasty population) consisting of younger patients (mean age, 50 vs. 61 years), who were more often male (75% vs. 45%), were more likely to have osteoarthritis as their primary diagnosis (83 vs. 67%) and were more often covered by managed care or commercial insurance (83 vs. 34%). They also had shorter hospital stays (mean length of stay, 2.3 vs. 4.1 days) and consequently provided a more favorable financial revenue stream to the hospital on a per patient basis. Several trends appeared during the study periods. There was a steady increase in all procedures in all groups except for the resurfacings, which decreased 26% in males and 53% in females between 2009 and 2010. Differences were observed in the demographics of patients presenting for resurfacing, compared to those presenting for conventional total hip arthroplasty. In addition to the revenue stream considerations, institutions undertaking a resurfacing program must commit the resources and planning in order to rehabilitate these patients more expeditiously than is usually required with conventional hip arthroplasty patients.
Full Text Available ntroduction: Reduced intrauterine space gives rise to ‘packaging disorder’ which may involve joint dislocations or contractures. We present an unique case where mutiple joints were dislocated involving left congenital knee dislocation (CDK, bilateral congenital hip dislocation (CDH and congenital talipes equino varus (CTEVdeformities. Case Report: A preterm baby boy born to mother with diagnosed oligohydramios presented with left CDK bilateral DDH and CTEV. The knee dislocation was treated first with gradual streaching and weekly above knee cast. At 7th week good flexion was achieved at both knees and abduction splint for DDH (using double diaper with ponseti cast for CTEV was done. At one year follow up all joints were reduced and maintained well with baby able to stand with support. Conclusion: Packaging disorders may present with multiple dislocations and deformities. Early intervention with serial casting and manipulation minimises disability and prevents ambulatory problems. In our case there was a good response to manipulation and serial casting. This differs from cases with inherent pathology like arthrogryposis where response to treatment is not so good.

A hyperdense line on the ilium that runs roughly parallel to the sacroiliac joint (we called it ''iliac hyperdense line sign'') was frequently observed on pelvic radiographs of patients with gluteal muscle contracture (GMC). A literature search revealed no description of this sign. To determine the relationship between the iliac hyperdense line sign and GMC and to explore how this sign is formed. Pelvic plain films of 103 cases of GMC and those of 200 control individuals were reviewed for the presence or absence of the iliac hyperdense line sign. Pelvic CT scans in 8 of 103 cases and 13 of 200 controls were analyzed with relation to the plain films. The iliac hyperdense line sign was visualized in 85 of 103 (82.5%) cases of GMC and none of the 200 controls. In the GMC group, pelvic CT scans showed a deformity of the posterior ilium. The lateral cortex of the posterior ilium took on a partly or completely anteroposterior course, while in the control group the course appeared as an oblique orientation from posteromedial to anterolateral. The iliac hyperdense line on pelvic plain film can be used as a radiographic sign to suggest a diagnosis of GMC. This sign might be a result of the long and persistent pulling effect of the contracted gluteus maximus muscle, which deforms the lateral cortex of the posterior ilium from an oblique course to an anteroposterior course tangential to the X-ray beam.

Full Text Available The paper deals with a rare monogenic connective tissue disease from a group of fibrillinopathies with autosomal dominant inheritance — Beals syndrome caused by a mutation in the FBN2 gene. Attention is drawn to the high phenotypic similarity of this disease and Marfan syndrome (FBN1 gene mutation, which is associated with the almost complete identity of two proteins: fibrillin 1 and fibrillin 2.The paper describes a clinical case of a child with Beals syndrome and the typical manifestations of the disease: asthenic constitution, arachnodactyly of the hands and feet, congenital contractures of the large and small joints, chest deformity, kyphoscoliosis, talpes, and crushed ears. The investigators made a differential diagnosis with other connective tissue diseases, such as Marfan syndrome, Stickler syndrome, Ehlers–Danlos syndrome, homocystenuria, and arthrogryposis. DNA diagnosis verified the Beals syndrome in the proband. Exon 28 in the FBN2 gene showed the previously undescribed missense mutation of c.3719G>A, resulting in the amino acid substitution of cysteine for tyrosine (p.Cys1240Tyr in the structure of the protein fibrillin 2. A de novo mutation occurred. There is evidence for its pathogenicity in the development of the clinical symptoms of the disease. The problems of effective medical genetic counseling in this family are discussed.

Knee flexion contracture (KFC) remains a common complication of haemoarthrosis in children and young adults with haemophilia. If the KFC is not treated properly it produces disability, postural and gait abnormalities. Evaluate the effectiveness of conservative treatment of KFC with Botulinum toxin type A (BTX-A) in PWH. Seventeen patients were treated, with 21 affected knees. Mean age was 26 years. The mean follow up was 12 months. We evaluated flexion and KFC pretreatment BTX-A and up to 12 months posttreatment. BTX-A application was in hamstring and calf muscles. To evaluate the function, a questionnaire about different activities was made, and it was checked 3, 6 and 12 months after BTX-A. According to the degree of KFC, knees were divided into 3 groups: Group 1: -10° to -30° (n = 10), Group 2: -31° to -45° (n = 6) Group 3: -46° or more (n = 5). The average KFC improved from -38° to -24°. The improvement was 14° (P KFC improvement was 9° in group 1, 17° in group 2, and 23° in group 3. There was a high correlation between the improvement in KFC and the total score of the questionnaire R = 0.77. Treatment of KFC with BTX-A improves knee-related functional activities, with the advantage of being a low-cost procedure and easy to apply. © 2015 John Wiley & Sons Ltd.

It is unknown how joint contracture is generated in inflamed joints. This study aimed to clarify the role of nociception on the formation of joint contracture secondary to arthritis. Monoarthritis was induced by intra-articular injections of complete Freund's adjuvant (CFA) into rat knees. On day 5 after CFA injection, the passive extension range of motion (ROM) of knee joints were measured, both before and after myotomy of knee flexors, to evaluate the extent of muscular contribution to CFA-induced joint contracture. The steroidal anti-inflammatory drug dexamethasone could prevent ROM restrictions completely, both before and after myotomy. On the other hand, the opioid analgesic drug morphine did not prevent the development of restricted ROM observed after myotomy, while it did before myotomy. This indicates that nociception contributes to joint contracture through alterations in muscular structure (myogenic factors). Next, we tested the hypothesis that nociception-induced reflexive flexor muscle contractions cause myogenic contracture in arthritic joints. To do this, chemical denervation was performed by Botulinum toxin type A (BTX-A) injections into knee flexor muscles, simultaneously with CFA injections into the knee. As expected, BTX-A could alleviate ROM restrictions observed before myotomy. These findings suggest that nociceptive-related muscle contractions play an essential role in the formation of joint contracture. Thus, our study indicates that analgesic management during an early stage of joint arthritis is an essential mean to prevent the formation of joint contracture. © 2016 Orthopaedic Research Society.

The Danish Hip Arthroscopy Registry (DHAR) was initiated in January 2012 as a web-based prospective registry. The purpose of this study was to evaluate and report the first registry based outcome data of a national population with radiological and clinical femoroacetabular impingement (FAI......) undergoing hip arthroscopic treatment. Our primary hypothesis was that patients undergoing hip arthroscopy would improve significantly in pain, quality of life and sports related outcome measurements in Patient Related Outcome Measures (PROM). Peri-operative data and Patient Reported Outcome Measures (PROM......-5 D demonstrated improvement after 1 and 2 years from 0.66 pre-op to 0.78 at 2 years. HSAS improved significantly from 2.5 to 3.3. Pain score data demonstrated improvement in NRS-rest 39 to 17 and NRS Walk 49 to 22 at follow-up. We conclude that patients with FAI undergoing hip arthroscopy...
Full text: Standard radiographs represent the basic tool of hip joint imaging. For detailed analysis of abnormalities related to bone marrow, articular cartilage, labrum and periarticular soft tissues, MRI has become the method of choice. MR arthrography is superior to standard MRI with regard to depicting the intra-articular abnormalities. CT is supporting plain radiographs for accurate depiction of subtle bone details. Ultrasound is commonly used in postoperative hematoma, bursitis, initial diagnosis of cysts and solid soft tissue tumors as well as for image guided injections and biopsies. Bone scintigraphy is suitable for the mapping of multifocal disease, such as osseous metastatic deposits. PET and PET/CT may be able to differentiate malignant neoplasm and infection from other abnormalities. A common disorder often requested for evaluation, is osteoarthritis. MRI is able to depict early degenerative changes which are occult on plain radiographs. CT- or MR arthrography provide a better evaluation of these changes but should only be performed in cases in which conservative surgery is considered to offer a significant clinical improvement for the patient. These cases include cam type femoroacetabular impingement and traumatic chondrolysis. MRI is an imaging technique that allows direct visualization of the bone marrow. Marrow disorders of the hip may induce a variety of imaging findings and frequently are not detected by conventional radiographic techniques until they have reached an advanced clinical stage. The excellent spatial and contrast resolution provided by MRI facilitates early detection and evaluation of various disorders allowing thus prompt treatment. Imaging findings may alter or guide the correct treatment. In addition, the association of marrow changes and pain such as in osteonecrosis and osteoarthritis is clinically relevant. For imaging the bone marrow, we use a combination of pulse sequences, including T1-w spin echo, PD/T2-w turbo spin echo

Posterior hip impingement is a recently-identified cause of hip pain. The purpose of this study is to characterise posterior femoroacetabular and ischiofemoral impingement and identify its predisposing morphologic traits. Two hundred and six cadaveric hips were randomly selected and taken through controlled motion in two pure axes associated with posterior hip impingement: external rotation (through the mechanical axis) and adduction (coronal plane). The range of motion and location of impingement was noted for each specimen. Morphologic traits including femoral/acetabular version, and true neck-shaft angle (TNSA) were also measured. External rotation impingement occurred between the femoral neck and acetabulum in 83.0% of hips, and between the lesser trochanter and ischial tuberosity in 17.0%. Adduction impingement occurred between the lesser trochanter and ischial tuberosity in 78.6% of hips, and between the femoral neck and acetabulum in 21.4%. Multiple regression revealed that increased femoral/acetabular version predicted earlier external rotation and adduction impingement. Unstandardised betas ranging from -0.39 to -0.64 reflect that each degree of increased femoral/acetabular version individually accounts for a loss of external rotation or adduction of approximately half a degree before impingement ( p < 0.001 for each). Increased TNSA was associated with earlier adduction impingement only (unstandardised beta -0.35, p = 0.005). Relative femoral/acetabular anteversion was associated with earlier posterior hip impingement. Coxa valga was associated with earlier adduction impingement, but protective against external rotation impingement. These findings highlight the importance of monitoring correction during femoral/acetabular osteotomies, as overcorrection of retroversion may predispose to earlier posterior impingement.

Collagenase Clostridium Histolyticum (CCH) is a recognised treatment option for adult patients presenting with Dupuytren's contracture (DC). Twenty male patients with established DC were treated using CCH. The average metacarpophalangeal (MCP) joint and proximal interphalangeal joint (PIP) contractures pre-treatment were 52 0 (range, 0 - 75 0 ) and 35 0 (range, 0 - 84 0 ) respectively. The average DASH score pre-treatment was 24.2 points (range, 0 - 68.2 points). Patients were reviewed at lmonth, 3months and at an average of 23 months (17 to 27 months). MCP joint contractures significantly improved compared to pre-treatment and the improvement was maintained at latest follow up. PIP joint contractures did significantly improve but to a lesser degree and there was no significant improvement compared to pre-treatment beyond 3months. A trend for MCP and PIP joint contracture recurrence was observed at latest follow up but did not reach statistical significance. DASH scores significantly improved from pre-treatment and the improvement was maintained at latest follow up. At 3months, the average patient satisfaction score was 9.5 (range, 6 - 10), which decreased to 8.6 (range, 6 - 10) at latest follow up. We estimated a potential cost saving of approximately £70,000 by treating 20 patients using CCH compared to inpatient operative fasciectomy. CCH is a useful option in the management of DC in appropriately selected patients. Cost-effectiveness in the treatment of DC should be carefully considered.

Purpose: To investigate the clinical and radiological characteristics of osteochondritis dissecans (OD) of the hip and the outcome of this condition after treatment. Material and Methods: Twelve male and 3 female patients with OD were retrospectively studied. Six patients had a history of Legg-Calve-Perthes disease (LCPD) and among them 2 also had had a trauma to the hip. A further 5 had had trauma and 1 a developmental dislocation of the hip (DDH). The remaining 3 patients had no history of previous hip disease or trauma. All patients were examined with plain radiography, 7 with MR, 3 with CT and 2 with hip arthrography. Results: All OD lesions were detected at plain radiography, and most of them were located near the fovea. At MR the lesions had low signal intensity at T1-weighted sequences, and 6/7 had edema or fluid collection in or adjacent to the lesion on T2-weighted sequences. The early treatment in 7 patients was surgery, 2 had had conservative treatment and 6 no treatment. At follow-up 12 years after radiological diagnosis, 5 patients had hip arthrosis, 4 of whom were treated with arthroplasty. All but 3 had reduced hip rotation and all but 2 (with arthroplasty) had load pain. Three of the patients with earlier surgery had not developed arthrosis. Conclusions: OD lesions are usually well seen with plain radiography. There is a great risk of developing early arthrosis and it seems that early surgery is connected with arthrosis development. Thus only symptomatic treatment is recommended

To describe changes in joint motion, sensibility, and scar pliability and to investigate the patients' expectations, self-reported recovery, and satisfaction with hand function, disability, and quality of life after surgery and hand therapy for Dupuytren disease. This prospective cohort study collected measurements before surgery and 3, 6, and 12 months after surgery and hand therapy. Ninety patients with total active extension deficits of 60° or more from Dupuytren contracture were included. Outcomes measures were range of motion; sensibility; scar pliability; self-reported outcomes on expectations, recovery, and satisfaction with hand function; Disabilities of the Arm, Shoulder, and Hand scores; safety and social issues of hand function; physical activity habits; and quality of life with the Euroqol. The extension deficit decreased, and there was a transient decrease in active finger flexion during the first year after surgery. Sensibility remained unaffected. Generally, patients with surgery on multiple fingers had worse scar pliability. The majority of the patients had their expectations met, and at 6 months, 32% considered hand function as fully recovered, and 73% were satisfied with their hand function. Fear of hurting the hand and worry about not trusting the hand function were of greatest concern among safety and social issues. The Disability of the Arm, Shoulder, and Hand score and the Euroqol improved over time. After surgery and hand therapy, disability decreased independent of single or multiple operated fingers. The total active finger extension improved enough for the patients to reach a functional range of motion despite an impairment of active finger flexion still present 12 months after treatment.

The purpose of this study was to examine the time-dependent changes in the development of joint capsule fibrosis and in the number of myofibroblasts in the joint capsule after immobilization, using a rat knee contracture model. Both knee joints were fixed in full flexion for 1, 2, and 4 weeks (immobilization group). Untreated rats were bred for each immobilization period (control group). Histological analysis was performed to evaluate changes in the amount and density of collagen in the joint capsule. The changes in type I and III collagen mRNA were examined by in situ hybridization. The number of myofibroblasts in the joint capsule was assessed by immunohistochemical methods. In the immobilization group, the amount of collagen increased within 1 week and the density of collagen increased within 2 weeks, as compared with that in the control group. Type I collagen mRNA-positive cell numbers in the immobilization group increased at all time points. However, type III collagen mRNA-positive cell numbers did not increase. Myofibroblasts in the immobilization group significantly increased compared with those in the control group at all time points, and they increased significantly with the period of immobilization. These results suggest that joint capsule fibrosis with overexpression of type I collagen occurs and progresses within 1 week after immobilization, and an increase in myofibroblasts is related to the mechanism of joint capsule fibrosis. The findings suggest the need for a treatment targeting accumulation of type I collagen associated with an increase in myofibroblasts. © 2017 Orthopaedic Research Society.

The purpose of this study was to document the prevalence, severity, and progression of knee flexion contractures (KFCs) in a population of institutionalized elderly and to identify relationships between knee extension and other variables. The subjects were 112 nursing home residents who exhibited a broad range of ambulation and cognitive function abilities. Data were collected initially (T1) and after a 10-month period (T2). Only 25% of the population had extension in the 0- to 5-degree (lacking full extension) range bilaterally at T1 and T2, leaving the majority of subjects with some degree of unilateral KFC. Most of the subjects with a KFC greater than 20 degrees were nonambulatory and had a significantly higher occurrence of resistance to motion than did nonambulators with a KFC of less than 20 degrees. Knee extension measurements did not change in most subjects between T1 and T2. The knees that did show a change in KFC (either an increase or a decrease) had a significantly higher occurrence of resistance to passive motion than did other knees. Compared with the subjects who gained extension, the subjects who lost extension over the study period more frequently had minimal KFC at T1, were ambulatory at T1, showed a regression in ambulation at T2, and developed resistance to motion at T2. The data confirmed significant positive correlations between degree of KFC and presence of resistance to passive knee motion, cognitive impairment, impaired ambulation, and presence of knee pain. Physical therapy assessment and intervention may be appropriate in nonambulatory nursing home residents with resistance to passive motion, residents with KFC approaching 20 degrees, and ambulatory residents with minimal KFC who develop resistance and begin to regress in ambulation. Several areas for future study are suggested.

Microinstability and ligament teres lesions are emergent topics on the hip pathology. These entities are an increasingly recognized cause of persistent hip pain and should be considered in the differential diagnosis of the patient with hip pain. Conventional (non-arthrographic) CT and MR have a very limited role in the evaluation of these entities. CTa and MRa have emerged as the modalities of choice for pre-operative imaging of ligamentum teres injuries and microinstability. To date, pre-operative imaging detection of these pathologies is not widespread but with appropriate imaging and a high index of suspicion, preoperative detection should improve. This article discusses current concepts regarding anatomy, biomechanics, clinical findings, diagnosis and treatment of ligament teres lesions and microinstability.

To investigate and compare the cytopathological and clinical effects of amniotic membrane transplantation (AMT) and oral mucosal membrane transplantation (OMMT) in socket contraction. Twelve patients who could not be fitted with ocular prosthesis due to socket contracture were included in this study. Seven patients underwent AMT and 5 patients underwent OMMT. Thirteen patients who had healthy sockets were included as control group. Depth of inferior fornix, degree of inflammation, extent of the socket contracture and socket volume were measured in the preoperative period and at sixth and twelfth weeks postoperatively. Impression cytology of conjunctival fornices and tear transforming growth factor beta-1 (TGFβ1) levels were determined. In the AMT group, socket volume and lower fornix depth values were significantly higher (P=0.030 and P=0.004 respectively) and inflammation levels and impression cytology stages (P=0.037 and P=0.022 respectively) were significantly lower in postoperative period compared to preoperative period. In the OMMT group, no statistical differences were found in terms of clinical parameters, inflammation levels and impression cytology stages of preoperative versus postoperative values. Preoperative tear TGFβ1 levels were higher in AMT and OMMT groups compared to the control group (25.5 ng/mL, 26.3 ng/mL and 21.7 ng/mL respectively). Decreased tear TGFβ1 levels were observed in both the AMT and OMMT groups postoperatively (median decrease value=2.1 ng/mL and 2.7 ng/mL respectively). AMT is associated with postoperative improvement in inferior fornix depth, socket volume, inflammation and impression cytology levels and may be a more proper alternative method than OMMT in the management of socket contracture.

To study the results and complications of percutaneous needle tenotomy for superficial retracted tendons in patients with brain damage. Prospective observational study. University hospital. Patients with severe brain damage (N=38; mean age, 60.7y; age range, 24-93y; 21 women) requiring surgical management of contractures and eligible for percutaneous needle tenotomy were enrolled between February 2015 and February 2016. The percutaneous needle tenotomy gesture was performed by a physical medicine and rehabilitation physician trained by an orthopedic surgeon, under local or locoregional anesthesia. Treated tendons varied among patients. All patients were evaluated at 1, 3, and 6 months to assess surgical outcomes (joint range of motion [ROM], pain, and functional improvement) while screening for complications. Improvements in ROM (37/38) and contractures-related pain (12/12) were satisfactory. Functional results were satisfactory (Goal Attainment Scale score ≥0) for most patients (37/38): nursing (n=12), putting shoes on (n=8), getting in bed or sitting on a chair (n=6), verticalization (n=7), transfers and gait (n=8), and grip (n=2). Five patients had complications related to the surgical gesture: cast-related complications (n=2), hand hematoma (n=2), and cutaneous necrosis of the Achilles tendon in a patient with previous obliterative arteriopathy of the lower limbs (n=1). Percutaneous needle tenotomy yields good results in the management of selected superficial muscle and tendon contractures. The complications rate is very low, and this treatment can be an alternative to conventional surgery in frail patients with neurologic diseases.

Full Text Available Restoration of the anatomy of the hip joint and biomechanics across it, carry the immense importance to prevent future osteoarthritis of the joint. The aim of this review is to provide the brief concept of the methods to preserve the hip, especially in young adults. Attempts to preserve the hips start with the intense preoperative planning of the corrective procedure. Different parameters regarding the femur and acetabulum in all 3 dimensions need to be assessed. Especially, measurement of the anteversion of the femur and acetabulum is a significant step to avoid osteoarthritis. In addition, the suprapelvic and infrapelvic (spine and lower limb lengths alignment needs to be considered in the planning. Correction of the femoral side of the hip needs the understanding of the blood supply of the proximal femur which carries the risk of avascular necrosis more so with intracapsular osteotomies. Acetabular reorientation, to re-distribute the forces over the weight bearing part, can be carried out with re-directional osteotomy such as periacetabular osteotomy. It needs the understanding of the acetabular anatomy and the force distribution in it. To conclude, correction of both femoral and acetabular side parameters need to be considered in decision making depending on the alterations due to various etiologies causing the hip disorders.
Objectives: To evaluate clinical features, treatment and relationship to the time period between dislocation, reduction and early complications of traumatic dislocation of hip in children. Methods: Case series conducted at Jinnah Post Graduate Medical Centre Karachi from July 2005 to August 2009. Children with traumatic hip dislocation up to fifteen years of age who presented in last four years were included in this study. Their clinical information, etiology, associated injuries, duration, method of reduction and early complications are evaluated through emergency room proforma and indoor record. Follow up of patient was updated in outpatient department. Results: We had eight patients, six boys and two girls. Youngest 2.4 years and eldest was 12 years with mean age of 6.2 +- 3.8 years. All presented with posterior hip dislocation. Etiology was road traffic accident in two and history of fall in remaining six patients. Average duration of time between dislocation and reduction was 19 hours range 3-72 hours. Dislocated hips were reduced under General Anaesthesia in two patients and under sedation analgesia in six patients. No complications were noted in eight cases with mean 18.75 +- 13.23 months follows up. Conclusion: Traumatic hip dislocation in children is not rare.

Full Text Available Introduction: In performing quadricepsplasty for contracture that develops after application of an external fixator for femoral fractures, surgeons must be aware of the potential risk for re-fracture and pin-related problems. The purpose of this report is to highlight these not well-detailed complications and to discuss specific findings and treatment suggestions.Case Report: 4 men (mean age, 40 years presenting with secondary to contracture that developed after application of an external fixator for femoral fractures were included in this study. The radiographs showed union across the fracture site however two of these patients couldn't stand on one leg raising suspicion about the union status. A computed tomographic image indeed demonstrated limited continuity of the cortex. Bone grafting was performed prior to quadricepsplasty. The mean extension and flexion before the quadricepsplasty were 0o and 570 , respectively. At the final follow-up examination, the mean active flexion of the knee had increased to 98o.Results: The incidence of re-fracture during and after quadricepsplasty has been reported to be between 10 and 25%. There are 2 preoperative features that may mislead surgeons into believing that complete union of the fractures has been attained: one is the patient's ability to stand on a single leg, and the other is the fact that plain radiographs may lend themselves to different interpretations. In such cases, computed tomography will provide evidence of the continuity of the cortical bone. Bone grafting in 2 of our patients is thought to have prevented the postoperative complications of re-fracture. Complications at pin sites induce contracture at surrounding structures. When extreme tightness of the skin is noted, a tension-releasing procedure such as a skin graft should be performed.Conclusion: In conclusion, re-fracture or pin-site contracture should be carefully managed before quadricepsplasty, because the patients who need a

More than twenty years ago, hydroxyapatite (HA), calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical experience includes the implantation of more than 4,000 cementless hydroxyapatite coated hip prostheses since 1990. The models implanted are coated with HA in the acetabulum and in the metaphyseal area of the stem. The results corresponding to survival and stability of implants were very satisfactory in the long-term. From our experience, HA-coated hip implants are a reliable alternative which can achieve long term survival, provided that certain requirements are met: good design selection, sound choice of bearing surfaces based on patient life expectancy, meticulous surgical technique, and indications based on adequate bone quality.

Full Text Available The authors define adolescence and developmental dysplasia of the hip (DDH. Special attention is paid to pathological findings characteristic of DDH in adolescence (unrecognized and untreated DDH; treated DDH, but non-terminated treatment; DDH diagnosed with delay, inadequately treated, with complications. The authors emphasise that DDH treatment has to be successfully terminated well before the adolescence; possibilities are explained on management modes at the time of adolescence, and possible persons guilty for the persistence of later hip problems are indicated. Based on the authors' experience and having in mind all surgical possibilities for the treatment (pelvic osteotomies, femoral osteotomies, trochanteroplasties, leg length equalization procedures the authors propose treatment protocols. The intention is to provide better treatment results and to prevent secondary hip arthrosis. Furthermore, how to improve the struggle against DDH is suggested.

Magnetic resonance imaging (MRI) is performed to diagnose many pathologic conditions affecting the hip joint. Either conventional MRI (without contrast enhancement of the joint cavity) or MR arthrography is used to detect and most accurately differentiate hip joint pathologies. Conventional MRI is performed in cases of bone marrow edema, necrosis, arthrosis and especially the so-called ''activated arthrosis'', as well as in inflammatory and tumorous entities. MR arthography, which has only recently become available for use, is excellently suited for diagnosing lesions of the acetabular labrum, cartilage lesions, and free articular bodies. This article provides an overview about MRI characteristics and their accuracy of hip joint diseases and the impact on the therapeutic procedure. (orig.)

The value of computed tomography in the assessment of abnormalities of the hip is demonstrated with the aid of an anatomical preparation and in patients with, respectively, congenital dislocation of a hip, dislocation of the hip in spina bifida, an acetabular fracture and a Ewing tumour. The anteversion of the acetabulum and femur and the instability index of the hip joint can be measured by means of computed tomography.

Certain athletic activities and lifestyles require a completely stable and very mobile hip. Total hip replacement with a natural femoral head size and two mobile-bearing surfaces (i.e., a "tripolar" prosthesis) is the most stable prosthesis. Elegant design and wear-resistant bearing surfaces are the keys to long-term implant survivorship. The hypothesis is that a ceramic-coated tripolar prosthesis using highly cross-linked polyethylene can provide full function and complete stability with low wear. This study sought to determine: (1) patient-reported outcomes, (2) functional outcomes, (3) implant survivorship and complications, and (4) postoperative sexual limitations. Between 1998 and 2011, the author performed 160 primary total hip replacements using tripolar prostheses in patients participating in adventure sports and other physically demanding activities. The institutional review board approved this study. The inclusion criteria were patients who needed unrestricted activity and who were not candidates for or did not choose hip resurfacing. Patients were followed every second year and assessed with radiographs, Harris Hip Score, WOMAC, SF-12, and UCLA functional outcome scores. Patients were asked about symptoms of instability and satisfaction with their hip replacement. Patients were asked both preoperatively and 2 years postoperatively four questions about their sexual activity. Mean follow-up was 11 years. At 2 years' postoperatively, 98% of patients reported their satisfaction as excellent or good and 99% were not limited for sexual activity following surgery. Seventy-four percent of patients reported they were recovered within 6 weeks of surgery. There were no dislocations. There were three revision procedures for implant loosening, infection, and periprosthetic fracture, but there were no failures of the tripolar articulation. The mean postoperative UCLA score was the highly athletic score of 8. There were no signs of osteolysis, wear, or metal
Intramuscular psoas lengthening during single-event multi-level surgery fails to improve hip dynamics in children with spastic diplegia. Clinical and kinematic outcomes in the short- and medium-terms.

In children with spastic diplegia, hip extension in terminal stance is limited by retraction of the psoas muscle, which decreases stride propulsion and step length on the contralateral side. Whether intramuscular psoas lengthening (IMPL) is effective remains controversial. The objective of this study was to assess the impact of IMPL as a component of single-event multi-level surgery (SEMLS) on spatial and temporal gait parameters, clinical hip flexion deformity, and hip flexion kinematics. IMPL as part of SEMLS does not significantly improve hip flexion kinematics. A retrospective review was conducted of the medical charts of consecutive ambulatory children with cerebral palsy who had clinical hip flexion deformity (>10°) with more than 10° of excess hip flexion in terminal stance and who underwent SEMLS. The groups with and without IMPL were compared. Preoperative values of the clinical hip flexion contracture, hip flexion kinematics in terminal stance, and spatial and temporal gait parameters were compared to the values recorded after a mean postoperative follow-up of 2.4±2.0 years (range, 1.0-8.7 years). Follow-up was longer than 3 years in 6 patients. Of 47 lower limbs (in 34 patients) included in the analysis, 15 were managed with IMPL. There were no significant between-group differences at baseline. Surgery was followed in all limbs by significant decreases in kinematic hip flexion and in the Gillette Gait Index. In the IMPL group, significant improvements occurred in clinical hip flexion deformity, walking speed, and step length. The improvement in kinematic hip extension was not significantly different between the two groups. Crouch gait recurred in 3 (8%) patients. The improvement in kinematic hip extension in terminal stance was not significantly influenced by IMPL but was, instead, chiefly dependent on improved knee extension and on the position of the ground reaction vector after SEMLS. IMPL remains indicated only when the clinical hip flexion

PDAC (also termed Matthew Wood) syndrome is a rare, autosomal recessive disorder characterized by pulmonary hypoplasia/aplasia, diaphragmatic defects, bilateral anophthalmia, and cardiac malformations. The disorder is caused by mutations in STRA6, an important regulator of vitamin A and retinoic acid metabolism. We describe six cases from four families of Hmong ancestry, seen over a 30 years period in California. These include: (i) consanguineous siblings with a combination of bilateral anophthalmia, diaphragmatic abnormalities, truncus arteriosus, and/or pulmonary agenesis/hypoplasia; (ii) a singleton fetus with bilateral anophthalmia, pulmonary agenesis, cardiac malformation, and renal hypoplasia; (iii) a sibling pair with a combination of antenatal contractures, camptodactyly, fused palpebral fissures, pulmonary agenesis, and/or truncus arteriosus; (iv) a fetus with bilateral anophthalmia, bushy eyebrows, pulmonary agenesis, heart malformation, and abnormal hand positioning. The phenotypic spectrum of PDAC syndrome has until now not included contractures or camptodactyly. Sequencing of STRA6 in unrelated members of families three and four identified a novel, shared homozygous splice site alteration (c.113 + 3_4delAA) that is predicted to be pathogenic. We hypothesize this may represent a unique disease allele in the Hmong. We also provide a focused review of all published PDAC syndrome cases with confirmed or inferred STRA6 mutations, illustrating the phenotypic and molecular variability that characterizes this disorder. © 2015 Wiley Periodicals, Inc.

Internal rotation contracture is the most common shoulder deformity in patients with brachial plexus birth injury. The purpose of this investigation is to describe the indications, technique, and results of the subscapularis slide procedure. The technique involves the release of the subscapularis muscle origin off the scapula, with preservation of anterior shoulder structures. A standard postoperative protocol is used in all patients and includes a modified shoulder spica with the shoulder held in 60 degrees of external rotation and 30 degrees of abduction, aggressive occupational and physical therapy, and subsequent shoulder manipulation under anesthesia with botulinum toxin injections as needed. Seventy-one patients at 2 institutions treated with subscapularis slide between 1997 and 2010, with minimum follow-up of 39.2 months, were identified. Patients were divided into 5 groups based on the index procedure performed: subscapularis slide alone (group 1); subscapularis slide with a simultaneous microsurgical reconstruction (group 2); primary microsurgical brachial plexus reconstruction followed later by a subscapularis slide (group 3); primary microsurgical brachial plexus reconstruction followed later by a subscapularis slide combined with tendon transfers for shoulder external rotation (group 4); and subscapularis slide with simultaneous tendon transfers, with no prior brachial plexus surgery (group 5). Full passive external rotation equivalent to the contralateral side was achieved in the operating room in all cases. No cases resulted in anterior instability or internal rotation deficit. Internal rotation contracture of the shoulder after brachial plexus birth injury can be effectively managed with the technique of subscapularis slide.

Collateral ligament shortening causes extension contractures of the metacarpophalangeal joint, and dynamic flexion splinting has been widely used to treat these contractures; however, there are various problems with these approaches. We developed a novel, pneumatic-type dynamic traction and flexion splint to solve these problems. A total of 25 fingers were treated with the dynamic traction and flexion splint for 8 weeks. Every 2 weeks, the average metacarpophalangeal joint flexion angle, total active motion, grasp strength, and pain scores were assessed. The finger flexion angle was significantly greater at the final evaluation, starting after 6 weeks of treatment (p < 0.05), than prior to treatment. Similarly, the total active motion results improved significantly over 8 weeks. Our results show that use of the dynamic traction and flexion splint improves patient finger functioning and flexural angle. The dynamic traction and flexion (DTF) splint appears to be effective for treating patients. © The International Society for Prosthetics and Orthotics 2015.

Twenty-two percent of institutionalised elderly persons have muscle contractures. Contractures have important functional consequences, rendering hygiene and positioning in bed or in a chair difficult. Medical treatment (such as botulinum toxin injections, physiotherapy or positioning) is not very effective and surgery may be required. Surgery is carried out in the operating theatre, under local or general anaesthesia but is often not possible in fragile patients. Mini-invasive tenotomy could be a useful alternative as it can be carried out in ambulatory care, under local anaesthesia. To evaluate the effectiveness of percutaneous needle tenotomy and the risks of damage to adjacent structures in cadavers. Thirty two doctors who had never practiced the technique (physical medicine and rehabilitation specialists, geriatricians and orthopaedic surgeons) carried out 401 tenotomies on the upper and lower limbs of 8 fresh cadavers. A 16G needle was used percutaneous following location of the tendons. After each tenotomy, a neuro-orthopaedic surgeon and an anatomist dissected the area in order to evaluate the success of the tenotomy and any adjacent lesions which had occurred. Of the 401 tenotomies, 72% were complete, 24.9% partial and 2.7% failed. Eight adjacent lesions occurred (2%): 4 (1%) in tendons or muscles, 3 (0.7%) in nerves and 1 (0.2%) in a vessel. This percutaneous needle technique effectively ruptured the desired tendons, with few injuries to adjacent structures. Although this study was carried out on cadavers, the results suggest it is safe to carry out on patients.

Distal limb contractures (DLC) represent a heterogeneous clinical and genetic condition. Overall, 20-25% of the DLC are caused by mutations in genes encoding the muscle contractile apparatus. Large interstitial deletions of the 3p have already been diagnosed by standard chromosomal analysis, but not associated with a specific phenotype. We report on four patients with syndromic DLC presenting with a de novo 3p14.1p13 microdeletion. The clinical features associated multiple contractures, feeding problems, developmental delay, and intellectual disability. Facial dysmorphism was constant with low-set posteriorly rotated ears and blepharophimosis. Review of previously reported cases with a precise mapping of the deletions, documented a 250 kb smallest region of overlap (SRO) necessary for DLC. This region contained one gene, EIF4E3, the first three exons of the FOXP1 gene, and an intronic enhancer of FOXP1 named hs1149. Sanger sequencing and locus quantification of hs1149, EIF4E3, and FOXP1 in a cohort of 11 French patients affected by DLC appeared normal. In conclusion, we delineate a new microdeletion syndrome involving the 3p14.1p13 locus and associated with DLC and severe developmental delay. © 2014 Wiley Periodicals, Inc.

Patients with spastic hemiplegia after upper motor neuron (UMN) injury can develop elbow contractures. This study evaluated outcomes of elbow releases in treating spastic elbow flexion contractures in hemiplegic patients. Adults with spastic hemiplegia due to UMN injury who underwent elbow releases (brachialis, brachioradialis, and biceps muscles) were included. Nonoperative treatment was unsuccessful in all patients. Patients complained of difficulty with passive functions. Passive range of motion (ROM), pain relief, Modified Ashworth spasticity score, and complications were evaluated preoperatively and postoperatively. There were 8 men and 21 women with an average age of 52.4 years (range, 24.1-81.4 years). Seventeen patients had pain preoperatively. Postoperative follow-up was a mean of 1.7 years (range, 1-4.5 years). Preoperatively, patients lacked a mean of 78° of passive elbow extension compared with 17° postoperatively (P .05). Releases of the brachialis, brachioradialis, and biceps muscles can be an effective means of pain relief, improved passive ROM, and decreased spasticity in patients with elbow flexion deformity after UMN injury.

Quengel casting was introduced in 1922 for nonsurgical treatment of knee flexion contractures (KFC) associated with hemophilic arthropathy. It consists of an extension-desubluxation hinge fixed to a cast allowing for gradual correction of a flexion deformity while preventing posterior tibial subluxation. The purpose of this study is to report 1 center's experience with this technique for the treatment of pediatric KFC. A retrospective review was conducted over a 26-year period. All patients with KFC treated with Quengel casting were included. Demographic data, associated medical conditions, adjunctive soft tissue releases, complications, and the need for late surgical intervention were recorded. Tibiofemoral angle measurements in maximal extension were recorded at initiation and termination of casting, 1-year follow-up, and final follow-up. Success was defined as no symptomatic recurrence of KFC or need for subsequent surgery. Eighteen patients (26 knees) were treated for KFC with Quengel casting. Average age at initiation of casting was 8.1 years with average follow-up of 59.9 months. Fifteen knees (58%) underwent soft tissue releases before casting. An average of 1.5 casts per knee were applied over an average of 23.9 days. Average KFC before casting was 50.6 degrees (range, 15 to 100 degrees) which improved to 5.96 degrees (0 to 40 degrees) at cast removal (Pcasting before 1 year. Of these, 11 knees (50%) had a successful outcome. Residual KFC of those treated successfully was 6.8 degrees (range, 0 to 30 degrees) at 1 year and 8.2 degrees (range, 0 to 30 degrees) at final follow-up, averaging 71.4 months (P=0.81). Of the 11 knees deemed failures, all had recurrence of deformity within an average of 1 year from cast removal. Surgical release before Quengel casting did not improve the chances for success (P=0.09). Quengel casting can improve pediatric KFC an average of 44.2 degrees with minimal complications. Although 50% of treated patients will demonstrate

Dupuytren's disease is a fibro-proliferative disorder affecting ~3-5% of the UK population. Current surgical treatments for Dupuytren's contracture (DC) include fasciectomy and fasciotomy. We assessed the clinical management of DC in England over a 5-year period; associated NHS costs were assessed for a 1-year period. Hospital Episode Statistics were extracted from April 2003 to March 2008 for patients with Palmar Fascial Fibromatosis (ICD10=M720) and DC-related procedures. Variables included demographics, OPCS, patient status and physician specialty. To estimate 2010-2011 costs, HRG4 codes and the National Schedule of Tariff 2010-11-NHS Trusts were applied to the 2007-2008 period. Over 5 years, 75,157 DC admissions were recorded; 64,506 were analyzed. Mean admissions per year were 12,901 and stable. Day cases increased from 42% (2003-2004) to 62% (2007-2008). The percent of patients having two or more admissions per year increased from 5.5% in 2003-2004 to 26.1% in 2007-2008. Between 2003 and 2007, 91% of procedures were Fasciectomy. Revision of Fasciectomy and Fasciotomy each accounted for ~4%; Amputation for 1%. In 2007, classification was extended to identify Digital Fasciectomy, its Revision and Dermofasciectomy. In 2007-2008, admissions were: 70% Palmar Fasciectomy, 16% Digital Fasciectomy, 1.3% Other Fasciectomy, 4.4% Revision of Palmar Fasciectomy, 1.3% Revision of Digital Fasciectomy, 3.8% Division of Palmar Fascia, 2.6% Dermofasciectomy and 1.1% Amputation. 79% of cases were overseen by trauma and orthopaedic surgeons, 19% by plastic surgeons. Mean (±SD) inpatient hospital length of stay was 1.5 (±1.4) days in 2003-2004 and 1.0 (±1.3) days in 2007-2008. Total estimated costs for 1 year (2010-2011) were £41,576,141. Per-patient costs were £2,885 (day case) and £3,534 (inpatient). Costs ranged from £2,736 (day-case Fasciectomy) to £9,210 (day-case Revision Digital). Between 2003 and 2008, fasciectomy was the most common surgical procedure for DC in

Partial myostatin loss may exaggerate selective muscle hypertrophy or atrophy/hypoplasia in GRMD dogs and worsen contractures. While muscle imbalance is not a feature of myostatin inhibition in mdx mice, findings in a larger animal model could translate to human experience with myostatin inhibitors.

The hip joint is the largest joint in the human body and consequently, its evaluation by diagnostic imaging is highly important. This includes imaging of hip joint arthroplasty, which is used to avoid joint immobility following a wide spectrum of diseases, such as end-stage degenerative disease, avascular necrosis of the femoral head or post-traumatic fractures. Conventional radiography is still the standard imaging modality for the evaluation of hip arthroplasty both directly following surgery and for periodical follow-up. In the majority of cases conventional radiography enables adequate assessment of early and late complications that can arise following hip arthroplasty, such as loosening, prosthetic or periprosthetic fracture, luxation, infection and soft tissue calcification. If the diagnosis cannot be established by means of radiography, advanced imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI), with or without injection of contrast media, may provide additional information. This is particularly true for the depiction of inflammatory processes. Regardless of the imaging modality used patients' clinical symptoms must also be taken into account in order to establish the correct diagnosis. (orig.) [de

Full Text Available 【Abstract】Femoral head fractures without dislocation or subluxation are extremely rare injuries. We report a neglected case of isolated comminuted fracture of femoral head without hip dislocation or subluxation of one year duration in a 36-year-old patient who sustained a high en- ergy trauma due to road traffic accident. He presented with painful right hip and inability to bear full weight on right lower limb with Harris hip score of 39. He received cementless total hip replacement. At latest follow-up of 2.3 years, functional outcome was excellent with Harris hip score of 95. Such isolated injuries have been described only once in the literature and have not been classified till now. The purpose of this report is to highlight the extreme rarity, possible mechanism involved and a novel classification system to classify such injuries.

Hip or groin pain in athletes is common and clinical presentation is often nonspecific. Imaging is a very important diagnostic step in the work-up of athletes with hip pain. This review article provides an overview on hip biomechanics and discusses strategies for hip imaging modalities such as radiography, ultrasonography, computed tomography, and magnetic resonance (MR) imaging (MR arthrography and traction MR arthrography). The authors explain current concepts of femoroacetabular impingement and the problem of high prevalence of cam- and pincer-type morphology in asymptomatic persons. With the main focus on MR imaging, the authors present abnormalities of the hip joint and the surrounding soft tissues that can occur in athletes: intraarticular and extraarticular hip impingement syndromes, labral and cartilage disease, microinstability of the hip, myotendinous injuries, and athletic pubalgia.

Man's evolution features two unique developments: growing a huge brain and upright gait. Their combination makes the pelvis the most defining skeletal element to read human evolution. Recent revival in joint preserving hip surgery have brought to attention morphological variations of the human hip that appear similar to hips of extant mammals. In man, such variations can produce hip osteoarthrosis through motion. We reviewed the evolution of the hip and pelvis with special interest in morphology that can lead to motion induced osteoarthrosis in man. The combination of giving birth to big brained babies and walking upright has produced marked differences between the sexes in pelvis and hip morphology, each having their characteristic mode of hip impingement and osteoarthrosis.

The aim of this study was to investigate the therapeutic effect of stretching combined with ultrashort wave on joint contracture and explore its possible mechanism. Thirty-two rabbits underwent unilateral immobilization of a knee joint at full extension to cause joint contracture. At 6 wks after immobilization, the rabbits were randomly divided into the following four groups: natural recovery group, stretching treatment group, ultrashort wave treatment group, and combined treatment group. For comparison, eight control group animals of corresponding age were also examined. The effect of stretching and ultrashort wave treatment on joint contracture was assessed by measuring the joint range of motion, evaluating the collagen deposition of joint capsule and assessing the mRNA and protein levels for transforming growth factor β1 in the joint capsule. The combined treatment group led to the best recovery of joint function. The combined treatment with stretching and ultrashort wave was more effective than stretching or ultrashort wave treatment alone against the synovial thickening of suprapatellar joint capsule, the collagen deposition of anterior joint capsule, and the elevated expression of transforming growth factor β1 in the joint capsule. Stretching combined with ultrashort wave treatment was effective in improving joint range of motion, reducing the biomechanical, histological, and molecular manifestations of joint capsule fibrosis in a rabbit model of extending joint contracture.

Tripolar implants were developed to treat unstable total hip arthroplasties. However, there is limited confirmation that they achieve this purpose despite their increasing use. Because they have a larger effective head size, these implants are expected to increase range of motion to impingement and improve stability in situations at risk for impingement compared with conventional implants. We assessed the range of motion to impingement using a tripolar implant mounted to an automated hip simulator using 22.2-mm and 28-mm femoral head sizes. The 22 and 28-mm tripolar implants provided increases of 30.5 degrees in flexion, 15.4 degrees in adduction, and 22.4 degrees in external rotation compared with the conventional 22.2-mm femoral head diameter implant. At the critical position of 90 degrees hip flexion, there was an increase of 45.2 degrees in internal rotation. At 0 degrees and 30 degrees external rotation, extension increases were 18.8 degrees and 7.8 degrees, respectively. Bony impingement was the limiting factor. Tripolar implants increased the arc of motion before impingement in positions at risk for dislocation and are expected to provide greater stability.

Brachial plexus birth palsy is frequently associated with internal rotation contractures of the shoulder as a result of muscle imbalance. The purpose of this study is to assess the effect of botulinum toxin A (BTX-A) injection in the subscapular (SC) muscle on external rotation and the need for tendon transfer for external rotation of the shoulder. A prospective comparative study was performed including 15 consecutive patients treated with BTX-A and a historic control group of 67 patients with mean age 30 months (SD 10). The BTX-A injection (2 IU/kg body weight) was performed immediately following MRI under general anesthesia in the SC muscle. Passive external rotation, the need for tendon transfer surgery, glenohumeral deformity, and muscle degeneration were evaluated. The hazard ratio for no relapse of internal rotation contracture after BTX-A injection compared with no BTX-A injection was calculated. In the BTX-A group, the passive external rotation in adduction increased from -1 degree (95% CI, -10 to 8) to 32 degrees (95% CI, 17-46) at 3 months and 6 patients were indicated for surgery compared with a decline from -2 degrees (95% CI, -7 to 3) to -11 degrees (95% CI, -17 to -6) in the control group with 66 indications for surgery. At 5 years of follow-up, 10 patients in the BTX-A group were indicated for surgery with a hazard ratio of 4.0 (95% CI, 1.9 to 8.4). BTX-A injection in the SC muscle of brachial plexus birth palsy patients can reduce internal rotation contractures and subsequently the need for tendon transfer surgery. At 5 years of follow-up a relapse was seen in 67% of the patients treated with BTX-A. Because at MRI less SC degeneration was found in the good responders on BTX-A treatment, this group seems to be the best target group. Further research is needed on patient selection for BTX-A injection including glenohumeral deformity, SC degeneration, as well as doses of BTX-A to be used. Level II-prospective comparative study.

Full Text Available Introduction. Pathological dislocation of the hip is one of the most severe complications of acute hematogenous osteomyelitis. The program of treatment for children with pathological hip dislocation is complex, but it has been sufficiently developed and implemented very successfully. At the same time, the available literature provides no cases of treating children with bilateral pathological hip dislocations after hematogenous osteomyelitis. There is no information on the incidence of such cases or in regards to remote functional results. Materials and methods. The results of the treatment of 18 children with bilateral pathological dislocation of the hip after hematogenous osteomyelitis are presented, which constituted 23.1% of the total number of patients (78 who underwent surgery in 2000–2016 for the diagnosis of pathological hip dislocation. Both hip joints were surgically operated on in 12 patients, while one hip joint was operated on in 6 patients. To assess the anatomical and functional state of hip joints, the clinical and roentgenological diagnostic techniques were used. Results and discussion. To stabilize and restore the function of the hip joints, 18 children underwent 30 surgical interventions: simple open hip reduction (19 and open hip reduction with hip arthroplasty with one (6 or two (5 demineralized osteochondral allogeneic grafts. The decision regarding the possibility of performing surgical intervention on the second hip joint was made only after a child's check-up examination was complete and after positive information about the anatomical and functional state of the operated hip joint was obtained. According to these criteria, 14 (77.8% children underwent surgical treatment of the second hip joint 1–1.5 years after the course of conservative measures to restore the range of motion in the previously operated hip joint. Over a period of 1–12 years, 17 patients were examined, 10 of which underwent an operation on both

Management of geriatric hip fractures in a protocol-driven center can improve outcomes and reduce costs. Nonetheless, this approach has not spread as broadly as the effectiveness data would imply. One possible explanation is that operating such a center is not perceived as financially worthwhile. To assess the economic viability of dedicated hip fracture centers, the authors built a financial model to estimate profit as a function of costs, reimbursement, and patient volume in 3 settings: an average US hip fracture program, a highly efficient center, and an academic hospital without a specific hip fracture program. Results were tested with sensitivity analysis. A local market analysis was conducted to assess the feasibility of supporting profitable hip fracture centers. The results demonstrate that hip fracture treatment only becomes profitable when the annual caseload exceeds approximately 72, assuming costs characteristic of a typical US hip fracture program. The threshold of profitability is 49 cases per year for high-efficiency hip fracture centers and 151 for the urban academic hospital under review. The largest determinant of profit is reimbursement, followed by costs and volume. In the authors’ home market, 168 hospitals offer hip fracture care, yet 85% fall below the 72-case threshold. Hip fracture centers can be highly profitable through low costs and, especially, high revenues. However, most hospitals likely lose money by offering hip fracture care due to inadequate volume. Thus, both large and small facilities would benefit financially from the consolidation of hip fracture care at dedicated hip fracture centers. Typical US cities have adequate volume to support several such centers.

Osteoporosis is characterized late in the course of the disease by an increased risk of fracture, particularly in the elderly. It occurs in both sexes, affecting approximately 8 million women and 2 million men aged > or = 50 years (1). While low bone density is a predictor of fractures, it is not the only determinant of fracture risk. Other factors include advanced age, altered bone quality, a personal or family history of falls, frailty, poor eyesight, debilitating diseases, and high bone turnover. A diet with sufficient calcium and vitamin D is important to minimize bone loss and, along with regular exercise, to maintain muscle strength. Bisphosphonates have been shown to reduce the risk of hip fracture. For elderly patients, the use of hip protectors may be used as a treatment of last resort. Regardless of the age of the patient, individual patient risk factors must be considered to target appropriate treatment and prevent fracture.

Hip and spine fractures represent just a portion of the burden of osteoporosis; however, these fractures require treatment and often represent a major change in lifestyle for the patient and their family. The orthopedic surgeon plays a crucial role, not only in the treatment of these injuries but also providing guidance in prevention of future osteoporotic fractures. This review provides a brief epidemiology of the fractures, details the surgical techniques, and outlines the current treatment...

The purpose of this case report is to describe a course of physical therapy for a client with a rare genetic condition, multiple pterygium syndrome (MPS). MPS is a rare genetic disorder characterized by connective tissue webbing across multiple joints, dysmorphic facies, and various visceral and skeletal deformities. Before the patient commenced physical therapy, surgical amputation was recommended for the client's knee flexion contracture. The client's treatment plan included stretching, manual therapy, and resisted exercise. Long-term outcomes were decreased back and knee pain and improved range of motion, strength, and ambulation. Therapists using techniques to improve joint range of motion in clients with MPS should be aware that pterygia may include contractile tissue, nerves, and blood vessels and there may be underlying skeletal deformity or weakness in these areas. Children with MPS are at high risk of developing scoliosis and should be appropriately assessed in early childhood.

A possible role for beta-adrenergic agonists in the management of bronchoconstriction resulting from exposure to anticholinesterase compounds was investigated in vitro in canine tracheal smooth muscle. Norepinephrine, salbutamol and isoproterenol produced partial relaxation of soman-induced contractures. However, the relaxation induced was not sustained; muscle tensions returned to pretreatment levels within minutes despite the continued presence of beta-agonists. Increasing cAMP levels with the non beta-agonist bronchodilators such as thoophylline, a phosphodiesterase inhibitor, or forskolin, a specific stimulator of adenylate cyclase, resulted in more complete and longer lasting relaxation, suggesting that beta-adrenoceptor desensitization may contribute to the failure by beta-agonists to produce sustained relaxation.

The purpose of this article is to give a general overview of femoroacetabular impingement (FAI) and how it could be treated arthroscopically, with some details about indications, the procedure itself and some of the complications associated with the surgery. FAI is a dynamic condition of the hip that can be a source of pain and disability and could potentially lead to arthritis. When symptomatic, and if conservative treatment fails, FAI can be addressed surgically. The goal of surgical treatment for FAI is to recreate the spherical contour of the femoral head, improve femoral offset, normalize coverage of the acetabulum, repair/reconstruct chondral damage and repair/reconstruct the labrum to restore normal mechanics and joint sealing. Advances in equipment and technique have contributed to an increase in the number of hip arthroscopy procedures performed worldwide and have made it one of the more common treatment options for symptomatic FAI. Hip arthroscopy is a procedure with an extremely steep and long learning curve. Cite this article: EFORT Open Rev 2018;3:121-129. DOI: 10.1302/2058-5241.3.170041 PMID:29780619

The success achieved with non-cemented hip arthroplasty depends mainly on the stability of the fixation, the quality of the stabilizing bone being just as important as favourable biomechanical conditions. The results of the intensive research and development with respect to the particular features of a non-cemented hip endoprosthesis can be divided into the following basic categories: Biomechanical aspects with special reference to bone related to the design of the prosthesis; material characteristics, such as fatigue strength, tribology, corrosion resistance, and biocompatibility; and development of new materials and coatings to permit direct bonding of implant and bone. With regard to the stem of hip prostheses, the different design parameters of various types are examined to determine their typical design characteristics, such as bearing surface of the collar, geometry of cross section, anatomically adapted shaping, and surface of the implant forming the contact with the bone. The latter can be divided into macroprofiles and macro- and micro-porous coated surfaces. On the other hand, the methods of cementless fixation of acetabular cups can be primarily divided into conical and spherical screw fixation and pegged fixation with additional macroprofiles of porous surfaces. In a separate study of the biomechanical aspects of screwed sockets, the special importance of socket shape and thread geometry are presented with reference to primary stability and long-term fixation of prostheses.

This paper presents a kinetic energy harvester designed to be embedded in a hip implant which aims to operate at a low frequency associated with body motion of patients. The prototype is designed based on the constrained volume available in a hip prosthesis and the challenge is to harvest energy from low frequency movements (< 1 Hz) which is an average frequency during free walking of a patient. The concept of magnetic-force-driven energy harvesting is applied to this prototype considering the hip movements during routine activities of patients. The magnetic field within the harvester was simulated using COMSOL. The simulated resonant frequency was around 30 Hz and the voltage induced in a coil was predicted to be 47.8 mV. A prototype of the energy harvester was fabricated and tested. A maximum open circuit voltage of 39.43 mV was obtained and the resonant frequency of 28 Hz was observed. Moreover, the power output of 0.96 μW was achieved with an optimum resistive load of 250Ω.

We explored regional variations in the surgical management of patients with Dupuytren's contracture (DC) in 12 European countries using a surgeon survey and patient chart review. Twelve countries participated: Denmark, Finland, Sweden (Nordic region); Czech Republic, Hungary, Poland (East); France, Germany, the Netherlands, UK (West); Italy, Spain (Mediterranean). For the survey, a random sample of orthopaedic/plastic surgeons (n = 687) with 3-30 years' experience was asked about DC procedures performed during the previous 12 months. For the chart review (n = 3357), information from up to five consecutive patients was extracted. Descriptive statistics are reported. Ninety-five per cent of all surgeons used fasciectomy for DC, followed by fasciotomy (70%), dermofasciectomy (38%) and percutaneous needle fasciotomy (35%). Most surgeons were satisfied with fasciectomy over other procedures. Recommended time away from work and duration of physical therapy increased with the invasiveness of the procedure. The intra-operative complication rate was 4.0%; the postoperative complication rate was 34%. Overall, ≥ 97% of the procedures were rated by surgeons as having a positive outcome. Across all regions, 54% of patients had no nodules or contracture after the procedures. Only 2% of patients required retreatment within the first year of surgery. Important inter- and intraregional differences in these aspects of patient management are described. Understanding current regional treatment patterns and their relationships to country-specific health systems may facilitate earlier identification of, and intervention for, DD and help to optimise the overall treatment for patients with this chronic condition. © 2013 Blackwell Publishing Ltd.
Full Text Available Twenty-two percent of institutionalised elderly persons have muscle contractures. Contractures have important functional consequences, rendering hygiene and positioning in bed or in a chair difficult. Medical treatment (such as botulinum toxin injections, physiotherapy or positioning is not very effective and surgery may be required. Surgery is carried out in the operating theatre, under local or general anaesthesia but is often not possible in fragile patients. Mini-invasive tenotomy could be a useful alternative as it can be carried out in ambulatory care, under local anaesthesia.To evaluate the effectiveness of percutaneous needle tenotomy and the risks of damage to adjacent structures in cadavers.Thirty two doctors who had never practiced the technique (physical medicine and rehabilitation specialists, geriatricians and orthopaedic surgeons carried out 401 tenotomies on the upper and lower limbs of 8 fresh cadavers. A 16G needle was used percutaneous following location of the tendons. After each tenotomy, a neuro-orthopaedic surgeon and an anatomist dissected the area in order to evaluate the success of the tenotomy and any adjacent lesions which had occurred.Of the 401 tenotomies, 72% were complete, 24.9% partial and 2.7% failed. Eight adjacent lesions occurred (2%: 4 (1% in tendons or muscles, 3 (0.7% in nerves and 1 (0.2% in a vessel.This percutaneous needle technique effectively ruptured the desired tendons, with few injuries to adjacent structures. Although this study was carried out on cadavers, the results suggest it is safe to carry out on patients.

Human skeletal muscles express three major myosin heavy chain (MyHC) isoforms: MyHCIIx (MYH1) in fast type 2B muscle fibers, MyHCIIa (MYH2) in fast type 2A fibers and MyHCI/β-cardiac MyHC (MYH7) in slow type I skeletal fibers and cardiac ventricles. In line with its expression pattern, MYH7 mutations have been reported in association with hypertrophic or dilated cardiomyopathy, skeletal myopathies or a combination of both. We analyzed the clinical and molecular phenotype of two unrelated families of Jewish Moroccan ancestry that presented with apparently autosomal dominant inheritance of progressive Laing-like distal myopathy with non-specific myopathic changes, but uncommon marked contractures and wasting of the neck extensors. Clinical phenotyping, whole exome sequencing and restriction analysis, generation of mutants followed by cell culture transfection and imaging. Using whole exome sequencing we identified in both families two novel heterozygous proline substitutions located in exon 31 of MYH7 within its rod domain: c.4309G>C (p.Ala1437Pro) and c.4301G>C (p.Arg1434Pro). Here we show that the phenotype caused by these mutations includes marked cervical muscle contracture, and report that the severity of the phenotype varies significantly, to the extent of non-penetrance in one of the families. Finally, we provide evidence that both proline substitutions impair myosin self-assembly in non-muscle cells transfected with β-myosin constructs carrying the mutations, but do not prevent incorporation of the mutant molecules into the sarcomere. This study expands our clinical and molecular knowledge of MYH7 rod mutations causing skeletal myopathies, and underscores the importance of discussing disease penetrance during genetic counseling.

The effect of simulated bilateral knee-flexion contractures (KFC) on the electromyographic (EMG) activity of the vastus lateralis was studied by testing 10 normal subjects using surface EMG to test the hypothesis that the activity of the knee extensors would increase as a function of the severity of the contracture. The root mean square of the EMG activity was determined from four 4-s samples taken at 30-s intervals, during 2 min of standing in each of five positions of simulated KFC (0 degree, 10 degrees, 20 degrees, 30 degrees and 40 degrees). A randomly balanced order of conditions was used. KFC were simulated in each subject by means of an adjustable line from the subject's waist to the sole of each foot. An analysis of variance was used to contrast EMG activity, and a significant difference was found between each of the positions (P less than 0.05). The mean (+/- 1 SD) EMG activity, expressed as a percentage of the maximum voluntary contraction, was 0.3% (+/- 0.2) at 0 degree, 7.6% (+/- 5.6) at 10 degrees, 10.9% (+/- 7.6) at 20 degrees, 16.6% (+/- 12.4) at 30 degrees and 24.0% (+/- 14.0) at 40 degrees. A linear relationship was found (r2 = 0.986), expressed by the equation y = 0.62 + 0.56 x, where y represents EMG activity and x represents the extent of simulated KFC (P = 0.0007). The results provide insight into the increased knee extensor activity necessary to stand with KFC and underline the importance of treating this common disorder.

Hip osteoarthritis (OA) is often associated with pain and impaired function. Understanding biomechanical alterations in patients with hip OA during challenging activities such as stair use is important to inform treatments. The aim of this study was to determine whether kinematics and kinetics during stair ambulation differed between people with hip OA and healthy controls. Fifteen participants with symptomatic and radiographic hip OA and 15 asymptomatic healthy controls underwent 3-D motion analysis during stair ascent and descent. Trunk, pelvis, and hip kinematics as well as hip kinetics were evaluated. Analyses were performed unadjusted and adjusted for speed and leg length. In both the unadjusted and adjusted analyses, participants with hip OA ascended stairs with less hip range of motion in all three planes and a lower peak external rotation moment compared to controls. In the unadjusted analysis, hip OA participants descended stairs with greater ipsilateral trunk lean, less sagittal plane range of motion, lower peak extension moment, lower peak external rotation moment, and greater hip adduction moment impulse compared to controls. In the adjusted results, peak internal rotation moment and hip adduction moment impulse were greater in hip OA participants compared to controls. Findings show that individuals with hip OA display limited range of hip joint movement, particularly during stair ascent, and overall indicate the use of strategies (e.g., trunk lean; lower peak external rotation moment; higher adduction moment impulse) that implicate altered hip abductor function. Future research is required to further understand the implications of these findings on hip OA. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Full Text Available Introduction: In relation to the study reporting the effects of applying phased complex rehabilitation in patients with total hip arthroplasty, it has been concluded that the everyday clinical practice in Bulgaria does not apply complex examination, giving an objective picture about the extent of functional status of patients with trauma and diseases of the hip. Aim: The main goal of this report is to present a test which incorporates all known and routine research and in which the total number of points determines the functional status of patients with trauma and diseases of the hip. Material and Methods: Based on the Hip dysfunction and Osteoarthritis Outcome Score, the Harris Hip Score modified test, scale D’Aubigne and Postel and Iowa’s test for complex functional evaluation of the hip joint, we have developed a test including information about the degree of pain; goniometry and manual muscle testing of the hip; locomotor test – type of gait and adjuvants; test for Daily Activities of Life. The test has been developed on the basis of expert assessment by doctors and physiotherapists of the proposed indicators for evaluation and determination of the weighting factors’ contribution to the general condition of the patient. Conclusion: The developed and tested method of complex functional assessment of the hip joint enables our colleagues, dealing with trauma and diseases of the hip, to use it in various research and scientific projects, as well as in general medical practice.

Hip joint is one of the largest weight-bearing structures in the human body. In the event of a failure of the natural hip joint, it is replaced with an artificial hip joint, known as hip joint prosthesis. The design of hip joint prosthesis must be such so as to resist fatigue failure of hip joint stem as well as bone cement, and minimize wear caused by sliding present between its head and socket. In the present paper an attempt is made to consider both fatigue and wear effects simultaneously in estimating functional-life of the hip joint prosthesis. The finite element modeling of hip joint prosthesis using HyperMesh™ (version 9) has been reported. The static analysis (load due to the dead weight of the body) and dynamic analysis (load due to walking cycle) have been described. Fatigue life is estimated by using the S-N curve of individual materials. To account for progressive wear of hip joint prosthesis, Archard's wear law, modifications in socket geometry and dynamic analysis have been used in a sequential manner. Using such sequential programming reduction in peak stress has been observed with increase in wear. Finally life is estimated on the basis of socket wear.

Although physiologic transition from rhythmic contractions to uterine retraction postpartum remains a poorly understood process, it has been shown that the latter is essential in the prevention of hemorrhage and its negative consequences. To investigate the transition from oscillatory contractions to tonic contracture in human myometrium after delivery, a mechanism purported to facilitate postpartum hemostasis. Protein kinase C (PKC) plays a key regulatory role in human uterine contractions because it can prevent dephosphorylation of regulatory proteins and sensitize the contractile machinery to low Ca 2+ . Thus, activation of PKC by phorbol 12,13-dibutyrate (PDBu) may act as a strong uterotonic agent. Uterine biopsies were obtained from consenting women undergoing elective caesarian delivery at term without labor (N = 19). Isometric tension measurements were performed on uterine strips (n = 114). The amplitudes and area under the curve of phasic contractions and tonic responses were measured and compared. A total of 1 μM PDBu was added to the isolated organ baths, and maximal tension of the uterine contracture was determined in the absence and presence of either 1 μM of staurosporine, 100 nM nifedipine, or 10 μM cyclopiazonic acid to assess the role of PKC and calcium sensitivity on uterine contractility. On the addition of PDBu on either basal or oxytocin-induced activity, consistent contractures were obtained concomitant with complete inhibition of phasic contractions. After a 30-minute incubation period, the mean amplitude of the PDBu-induced tone represented 65.3% of the amplitude of spontaneous contraction. Staurosporine, a protein kinase inhibitor, induced a 91.9% inhibition of PDBu contractures, a process not affected by nifedipine or cyclopiazonic acid, thus indicating that this mechanism is largely Ca 2+ independent. Pharmacologic activation of PKC leads to a significant contracture of the myometrium. Together, these data suggest that the up

The objective of this study was to define, in unilateral hip osteoarthritis (OA), factors predicting the outcome of the other hip. We examined the anteroposterior radiographs of the pelvis of 95 white patients with unilateral idiopathic (56 patients) or secondary to congenital hip diseases (39 patients) OA. The other hip was free from symptoms (pain or limping) at the initial examination and without radiographic evidence of OA; it was what we call a ''normal'' hip. Two parameters were evaluated: (1) the type of osteoarthritis of the involved hip and (2) the range of four radiographic indices of the contralateral hip: the sourcil inclination (weight-bearing surface), the acetabular angle, the Wiberg's center-edge angle, and the neck-shaft angle. Follow-up radiographs for the hips that remained OA-free were available for 10 to 35 years and for those that developed OA, at the time of initial symptoms, range 2 to 31 years. Logistic regression analysis showed that the presence of idiopathic OA in one hip had a statistically significant effect on the development of OA on the other hip (p<0.001). Minor deviations of radiographic indices of the contralateral hip is not a predictive factor for its outcome. When the radiographic indices are examined together with the pathology of the involved hip, only WBS was shown to have a significant effect to the development of OA and its type (p < 0.001). The following conclusions can be drawn from this study: 1. Patient with idiopathic OA of one hip is at increased risk of developing OA in the other hip. 2. The outcome of the other hip cannot be predicted only on the basis of the evaluation of its radiographic indices. 3. Among the different indices, WBS seems to have a strong influence toward the development of OA. (orig.)

Total hip arthroplasty (THA) is an increasingly common procedure among elderly individuals. Although conversion THA is currently bundled in a diagnosis related group (DRG) with primary THA, there is a lack of literature supporting this classification and it has yet to be identified whether conversion THA better resembles primary or revision THA. This editorial analyzed the intraoperative and postoperative factors and functional outcomes following conversion THA, primary THA, and revision THA to understand whether the characteristics of conversion THA resemble one procedure or the other, or are possibly somewhere in between. The analysis revealed that conversion THA requires more resources both intraoperatively and postoperatively than primary THA. Furthermore, patients undergoing conversion THA present with poorer functional outcomes in the long run. Patients undergoing conversion THA better resemble revision THA patients than primary THA patients. As such, patients undergoing conversion THA should not be likened to patients undergoing primary THA when determining risk stratification and reimbursement rates. Conversion THA procedures should be planned accordingly with proper anticipation of the greater needs both in the operating room, and for in-patient and follow-up care. We suggest that conversion THA be reclassified in the same DRG with revision THA as opposed to primary THA as a step towards better allocation of healthcare resources for conversion hip arthroplasties.

To provide a comprehensive review of outcomes associated with local anesthetic (LA) or LA and corticosteroid (CS) diagnostic hip injections, and how well response predicts subsequent operative success. A systematic review from database (PubMed, Medline, Scopus, Embase) inception to January 2015 for English-language articles reporting primary patient outcomes data was performed, excluding studies with >50% underlying osteoarthritis. Studies were assessed by 2 reviewers who collected pertinent data. Seven studies were included, reporting on a total 337 patients undergoing diagnostic hip injection. The mean age was 34.4 years, with 5 studies reporting 94 (35.2%) males and 173 (64.8%) females. One study examined the rate of pain relief with LA (92.5%); 2 CS studies reported relief on a scale from 0% to 100% (no to complete relief), ranging from 61% to 82.3%; and 3 studies used 10-point pain scales, with a CS study noting a pain score of 1.0, an LA study with a score of 3.03, and 1 study using either CS or LA scores of 3 to 5.6. Duration of pain relief was 9.8 (CS) and 2.35 days (LA). By pathology, greatest relief was achieved in acetabular chondral injury (93.3%) and least in cam impingement (81.6%), with clinical and imaging findings being unreliable predictors of relief. One study showed nonresponse to be a strong predictor of negative surgical outcome for femoroacetabular impingement. Diagnostic hip injections provide substantial pain relief for patients with various hip pathologies, with limited data to suggest greatest relief for those with chondral injury. Clinical and imaging findings are unreliable predictors of injection response, and nonresponse to injection is a strong negative predictor of surgical outcome. Future research should focus on elucidating differences by underlying pathology and predicting future operative success. Level IV, systematic review.

Full Text Available Congenital hip luxation is a disorder which evolves in time. Teratological hip dislocation is a distinct form of hip luxation, which usually appears with other disorders. These hips are dislocated before birth. In this thesis we will try to elaborate a recovery program, through physical exercises, which will help us realize our treatment objectives: diminishing articular stiffness, increasing articular mobility, increasing muscle strength, recalibration of agonist and antagonist balances and reeducating gait. The specific objectives of the study consist of the particularization of the recovery programs based on age, illness stage (dysplasia or luxation and either surgical or non-surgical intervention. To show the importance of physiotherapy in gait rehabilitation of a child with hip dislocation we started from the hypothesis: using an adequate rehabilitation program after an individualized methodology, optimizes the functional recovery and ensures the gains of hip stability and the formation of an engram of gait as close as it could be to the normal one. We present a case of neurological congenital hip dislocation where the treatment initiated early is showing good results. Results obtained are significantly different and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient has better biomechanical results for the hip.

Pertunjukan Teater Karo Hip Hop Kontemporer KAI. The performance of Karo Theater collaborated with Hip Hop stems from a simple idea to collaborate Karo cultural traditions with popular culture. The performances can be enjoyed without having limitation on the language and culture. The process of combining two different cultures is a form of hybrid culture, and it may occur due to the globalization process. Through the process of deposition of the observations and strong impression, this performance is then brought into the form of Hip Hop as a preferred form which is energetic, personal and global. This performance is part of a modern tragedy with its destructive character which has explored the emotion and has presented it to the audiences. The exploration of Karo cultural tradition and Hip Hop dance as a language of symbols is able to reinforce words. The movement is not revealed by the verbal phrase but is presented through the movement of Hip Hop dance. The interpretation of the legend and texts into movement is carried out through the training process at the laboratory as a searching process and experiment, and afterward can be realized by considering the basic elements of Hip Hop, Karo cultural elements and performance. Karo Hip Hop Theatre is expected to become a preferred aesthetic form of a modern theater without losing its tradition form. Keyword: a contemporary Karo theater, Hip Hop, hybrid culture.

Hereditary Fibrosing Poikiloderma (HFP) with tendon contractures, myopathy and pulmonary fibrosis (POIKTMP [MIM 615704]) is a very recently described entity of syndromic inherited poikiloderma. Previously by using whole exome sequencing in five families, we identified the causative gene, FAM111B (NM_198947.3), the function of which is still unknown. Our objective in this study was to better define the specific features of POIKTMP through a larger series of patients. Clinical and molecular data of two families and eight independent sporadic cases, including six new cases, were collected. Key features consist of: (i) early-onset poikiloderma, hypotrichosis and hypohidrosis; (ii) multiple contractures, in particular triceps surae muscle contractures; (iii) diffuse progressive muscular weakness; (iv) pulmonary fibrosis in adulthood and (v) other features including exocrine pancreatic insufficiency, liver impairment and growth retardation. Muscle magnetic resonance imaging was informative and showed muscle atrophy and fatty infiltration. Histological examination of skeletal muscle revealed extensive fibroadipose tissue infiltration. Microscopy of the skin showed a scleroderma-like aspect with fibrosis and alterations of the elastic network. FAM111B gene analysis identified five different missense variants (two recurrent mutations were found respectively in three and four independent families). All the mutations were predicted to localize in the trypsin-like cysteine/serine peptidase domain of the protein. We suggest gain-of-function or dominant-negative mutations resulting in FAM111B enzymatic activity changes. HFP with tendon contractures, myopathy and pulmonary fibrosis, is a multisystemic disorder due to autosomal dominant FAM111B mutations. Future functional studies will help in understanding the specific pathological process of this fibrosing disorder.
Full Text Available Abstract Background Malignant hyperthermia (MH is triggered by halogenated anaesthetics and depolarising muscle relaxants, leading to an uncontrolled hypermetabolic state of skeletal muscle. An uncontrolled sarcoplasmic Ca2+ release is mediated via the ryanodine receptor. A compensatory mechanism of increased sarcoplasmic Ca2+-ATPase activity was described in pigs and in transfected cell lines. We hypothesized that inhibition of Ca2+ reuptake via the sarcoplasmic Ca2+-ATPase (SERCA enhances halothane- and caffeine-induced muscle contractures in MH susceptible more than in non-susceptible skeletal muscle. Methods With informed consent, surplus muscle bundles of 7 MHS (susceptible, 7 MHE (equivocal and 16 MHN (non-susceptible classified patients were mounted to an isometric force transducer, electrically stimulated, preloaded and equilibrated. Following 15 min incubation with cyclopiazonic acid (CPA 25 μM, the European MH standard in-vitro-contracture test protocol with caffeine (0.5; 1; 1.5; 2; 3; 4 mM and halothane (0.11; 0.22; 0.44; 0.66 mM was performed. Data as median and quartiles; Friedman- and Wilcoxon-test for differences with and without CPA; p Results Initial length, weight, maximum twitch height, predrug resting tension and predrug twitch height of muscle bundles did not differ between groups. CPA increased halothane- and caffeine-induced contractures significantly. This increase was more pronounced in MHS and MHE than in MHN muscle bundles. Conclusion Inhibition of the SERCA activity by CPA enhances halothane- and caffeine-induced contractures especially in MHS and MHE skeletal muscle and may help for the diagnostic assignment of MH susceptibility. The status of SERCA activity may play a significant but so far unknown role in the genesis of malignant hyperthermia.

T1-weighted (repetition time [TR] = 450 msec, echo time [TE] = 20 msec), T2-weighted (TR = 1,800 msec, TE = 20 and 80 msec), and T2*-weighted gradient-echo gradient recalled acquisition in a steady state, TR = 70 msec, TE = 30 msec, theta = 15 0 ) MR images (General Electric Signa, 1.5 T) were generated in 11 patients with avascular necrosis of the hip. Three-dimensional MR image reconstruction was performed on an independent imaging system (IIS, Dimensional Medicine Inc). Pelvic and femoral bone contours were computed based on either the T1-weighted or the T2*-weighted images. Three-dimensional displays of necrotic zones and areas of granulation tissue were computed on the basis of the T2-weighted images. The tissues were simultaneously displayed in the three-dimensional images using different colors and transparencies. The three-dimensional MR images generated demonstrated the extent of the necrotic zone and adjacent granulation tissue and their position relative to the weight-bearing surface. They may soon prove to be useful in preoperative planning and intraoperative localization of complex surgical interventions in avascular necrosis of the hip
Full Text Available Abstract Background The aim of the present study is to analyze the incidence of hip fracture as a complication of admissions to internal medicine units in Spain. Methods We analyzed the clinical data of 2,134,363 adults who had been admitted to internal medicine wards. The main outcome was a diagnosis of hip fracture during hospitalization. Outcome measures included rates of in-hospital fractures, length of stay and cost. Results A total of 1127 (0.057% admittances were coded with an in-hospital hip fracture. In hospital mortality rate was 27.9% vs 9.4%; p Conclusions In-hospital hip fracture notably increased mortality during hospitalization, doubling the mean length of stay and mean cost of admission. These are reasons enough to stress the importance of designing and applying multidisciplinary plans focused on reducing the incidence of hip fractures in hospitalized patients.

Physiologic motor and biomechanical parameters are prerequisites for normal hip development and hip function. Disorders of muscle activity and lack of weight bearing due to neuromuscular diseases may cause clinical symptoms such as an unstable hip or reduced range of motion. Disability and handicap because of pain, hip dislocation, osteoarthritis, gait disorders, or problems in seating and positioning are dependent on the severity of the disease, the time of occurrence, and the means of prevention and treatment. Preservation of pain-free and stable hip joints should be gained by balancing muscular forces and by preventing progressive dislocation. Most important is the exact indication of therapeutic options such as movement and standing therapy as well as drugs and surgery.
Full Text Available It is standard practice in many institutions to routinely perform preoperative and postoperative haemoglobin level testing in association with hip joint arthroplasty procedures. It is our observation, however, that blood transfusion after uncomplicated primary hip arthroplasty in healthy patients is uncommon and that the decision to proceed with blood transfusion is typically made on clinical grounds. We therefore question the necessity and clinical value of routine perioperative blood testing about the time of hip resurfacing arthroplasty. We present analysis of perioperative blood tests and transfusion rates in 107 patients undertaking unilateral hybrid hip resurfacing arthroplasty by the senior author at a single institution over a three-year period. We conclude that routine perioperative testing of haemoglobin levels for hip resurfacing arthroplasty procedures does not assist in clinical management. We recommend that postoperative blood testing only be considered should the patient demonstrate clinical signs of symptomatic anaemia or if particular clinical circumstances necessitate.

To evaluate the minimum 2-year postoperative clinical outcomes and the rate of return to sports in athletes who underwent capsular plication for the treatment of ligamentous laxity and/or borderline dysplasia during hip arthroscopy for the treatment of femoroacetabular impingement and labral pathology. Since 2008, data were prospectively collected on patients who underwent hip arthroscopy for the treatment of femoroacetabular impingement and/or labral tears. Inclusion criteria were as follows: athlete at the high school, collegiate, or professional levels preoperatively, underwent capsular plication, and preoperatively recorded patient-reported outcome scores including modified Harris hip score (mHHS), nonarthritic athletic hip score (NAHS), hip outcome score-sports-specific subscale (HOS-SSS), and visual analog scale (VAS). Exclusion criteria were as follows: 1, and previous hip conditions. Sports activity and competitive levels were collected at a minimum of 2 years postoperatively. Fifty-one hips (49 patients) met the inclusion criteria, and 41 hips (39 patients) had minimum 2-year follow-up (80.4% follow-up). Mean mHHS increased from 67.1 preoperatively to 83.5 (P arthroscopies allowed the patients to return to sports at follow-up. Thirty-four (82.9%) hip arthroscopies allowed the patients to maintain their competitive physical abilities at follow-up. Patient-reported outcomes and VAS in athletes significantly improved at a minimum of 2 years after capsular plication as a part of hip arthroscopy addressing varying pathologies. In addition, most patients returned to sports at similar or higher competitive levels. These results suggest that capsular plication is a favorable treatment option in athletes with ligamentous laxity and/or borderline dysplasia. Level IV, therapeutic case series.

Since Dupuytren's contracture is a common disorder, the costs for its surgical treatment impose a considerable burden on the healthcare system. For the first time in the German-speaking area, this study aimed to provide a comparative cost-effectiveness analysis for partial fasciectomy vs. treatment with Clostridium histolyticum collagenase (CCH). A retrospective monocentric study of the period from 2012 to 2014 comprised 40 patients with previously untreated Dupuytren's contracture of one finger. 20 outpatients received one CCH treatment (Group 1), while 20 inpatients underwent partial fasciectomy (Group 2). The direct pre-interventional treatment and post-interventional costs were compared. The direct post-interventional and postoperative results were comparable. Group 1 (CCH) showed a mean reduction in contracture of 96.4%; in Group 2 (partial fasciectomy), this was 97.7%. There were fewer complications in Group 1 than in Group 2. Mean treatment costs in Group 1 were € 1 458.60 and in Group 2, € 5 315.20. Treatment with CCH is more cost effective than with partial fasciectomy. This is due to greater costs for personnel, time and surgical material, as well as the treatment of the more frequent complications in Group 2. Despite the limited comparability, our findings are consistent with the present international literature. © Georg Thieme Verlag KG Stuttgart · New York.

No study has ever evaluated the causes and effect of neglect on the outcome of post burns contractures of hand in children. 66 hands in 61 children (mean age 12.22 years) with a mean neglect of 11.6 years (range 5-17 years) were assessed for the causes of neglect and the outcome of surgery. Average follow up was 6.6 years. The results were assessed in two groups of 5-10 years neglect as group I and >10 years neglect as group II. In a total number of 134 contracted rays in 66 hands, the surgical procedures included local Z/V-Y flap (51 rays), cross finger flap (48 rays), full thickness graft (35 rays). Additional external fixator with a distracter was used in 3 patients treated at a delay of 14, 16 and 17 years. 50 (81.96%) patients belonged to rural and slum areas. The reasons for delayed treatment included poverty - 33 patients, lack of awareness of surgical treatment - 16 patients; and indifference of parents - 12 patients. 44 (72.13%) children were illiterates. With treatment the average DASH score improved from 65.10 to 36.90 (p neglect in treatment of post burns contracture include poverty, lack of awareness and illiteracy. All the patients showed significant improvement in function after the surgery. Contractures with higher neglect had significantly inferior outcome.

The involvement of the musculoskeletal system with other mild pleiotropic manifestations represents a clinical criterion, called "systemic features," to d iagnose Marfan's syndrome. We aimed to investigate the features of the hands and feet redressable contractures present in a group of Marfan patients. In 13 patients with previously diagnosed Marfan's syndrome, an accurate clinical examination was performed. In particular the characterization of the musculoskeletal system by visual analogic scale to measure muscle pain (VAS) and muscle strength (MRC system) was carried out; the Beighton scale score was used to evaluate the articular hypermobility. Ultrasound examination (US) was performed to detect deep-superficial flexor tendons and extensor tendons of both hands, and the short and long flexor and extensor tendons of the fingers and toes in static and dynamic positions. The ImageJ program was adopted to measure a profile of tendon echo-intensity. A reduction of the thickness of all tendons was detected by US in our patients; the VAS and Beighton scale scores were in normal ranges. The profile of tendon echo-intensity showed different textural details in all Marfan patients. This study provides evidence for other contractures' localization, and for altered findings of the tendons in patients with Marfan syndrome and finger/toe contractures. These changes may be associated with structural modifications in connective tissue.

To investigate effects of surface neuromuscular electrical stimulation applied early after stroke to the wrist and finger extensor muscles on upper limb pain, spasticity and contractures in patients with no functional arm movement. Secondary analysis from a Phase II, randomized, controlled, single-blind study. An acute hospital stroke unit. Patients with no useful arm function within six weeks of a first stroke. Patients were randomized to treatment (30-minute sessions of surface neuromuscular stimulation to wrist and finger extensors and 45 minutes of physiotherapy) or control (45 minutes of physiotherapy) groups. All patients had access to routine care. Treatment was given for six weeks from recruitment. Ninety patients (49% male, median age 74 years (range 32-98), median time since stroke onset three weeks (range one to six weeks)) were included. Treatment compliance was variable (mean 28%). The treatment prevented the development of pain (mean difference in rate of change 0.4 units/week, 95% confidence interval (CI) 0.09 to 0.6). Treatment may have prevented a deterioration in contractures (quantified by measuring passive range of movement) in severely disabled patients (mean rate of deterioration -0.5 deg/week; 95% CI -0.9 to -0.06). There were no significant changes in stiffness and spasticity. Surface neuromuscular electrical stimulation reduces pain in stroke patients with a non-functional arm. There was some evidence that treatment with electrical stimulation was beneficial in reducing contractures. Treatment had no effect on spasticity.

Children with cerebral palsy (CP) and acquired brain injury (ABI) commonly develop muscle contractures with advancing age. An underlying growth defect contributing to skeletal muscle contracture formation in CP/ABI has been suggested. The biceps muscles of children and adolescents with CP/ABI (n=20) and typically developing controls (n=10) were investigated. We used immunohistochemistry, qRT-PCR and western blotting to assess gene expression relevant to growth and size homeostasis. Classical pro-inflammatory cytokines and genes involved in extracellular matrix production were elevated in skeletal muscle of children with CP/ABI. Intramuscular collagen content was increased and satellite cell number decreased and this was associated with reduced levels of RNA polymerase (POL) I transcription factors, 45s pre-rRNA and 28S rRNA. The present study provides novel data suggesting a role for pro-inflammatory cytokines and reduced ribosomal production in the development/maintenance of muscle contractures; possibly underlying stunted growth and perimysial extracellular matrix expansion.

In this study we investigated the molecular mechanism underlying muscle contracture in rats. The rats were divided into immobilization and control groups, and soleus muscles of the right and left sides were selected for analyses. The levels of CD11b and α-SMA protein, IL-1β, and TGF-β1 mRNA, and type I and III collagen protein and mRNA were significantly greater in the immobilization group than in the control group at all time-points. HIF-1α mRNA levels were significantly higher in the immobilization group at 4 weeks. Moreover, HIF-1α, α-SMA, and type I collagen levels were significantly higher at 4 weeks than at 1 and 2 weeks in the immobilization group. In the early stages of immobilization, upregulation of IL-1β/TGF-β1 via macrophages may promote fibroblast differentiation that could affect muscle contracture. The soleus muscle became hypoxic in the later stages of immobilization, suggesting that hypoxia influences the progression of muscle contracture. © 2014 Wiley Periodicals, Inc.

Management of a knee contracture is important for regaining gait ability in transtibial amputees. However, there has been little study of prosthesis training for enhancing mobility and improving range of motion in cases of restricted knee extension. This study aimed to evaluate the effects of adaptive training for an assist device (ATAD) for a transtibial amputee with a knee flexion contracture (KFC). A male transtibial amputee with KFC performed 4 months of ATAD with a multidisciplinary team. During the ATAD, the passive range of motion (PROM) in the knee, amputee mobility predictor (AMP) assessment, center of pressure (COP) on a force plate-equipped treadmill, gait features determined by three-dimensional motion analysis, and Short-Form 36 Item Health Survey (SF-36) scores were evaluated. Following ATAD, PROM showed immediate improvement (135.6 ± 2.4° at baseline, 142.5 ± 1.7° at Step 1, 152.1 ± 1.8° at Step 2, 165.8 ± 1.9° at Step 3, and 166.0 ± 1.4° at Step 4); this was followed by an enhanced COP. Gradually, gait features also improved. Additionally, the AMP score (5 at baseline to 29 at Step 4) and K-level (K0 at baseline to K3 at Step 4) increased after ATAD. Along with these improvements, the SF-36 score also improved. ATAD could be beneficial for transtibial amputees by relieving knee contractures and improving gait.

To determine the safety and efficacy of hip arthroscopy performed in the peripheral compartment as a diagnostic and therapeutic treatment option for patients with hip pain after hip resurfacing surgery. Indications for hip arthroscopy after hip resurfacing included patients with a symptomatic hip-resurfaced arthroplasties who did not respond to nonoperative treatment. Patients who underwent a hip arthroscopy after a painful hip resurfacing were included with a minimum of 1 year follow-up. Subgroup analysis was performed according to whether an established diagnosis was made before arthroscopic intervention or not. Subjective measures were based on Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, and results were calculated and analyzed. We included 68 patients (26 male [38%] and 42 female [62%]) who underwent subsequent hip arthroscopy from a population of 978 consecutive hip-resurfaced arthroplasties performed between 1999 and 2010. The average age was 58 (range, 37 to 78 years). The mean follow-up after hip arthroscopy was 3.4 years (range, 12 months to 5.8 years). Patients who had an established diagnosis (n = 41) before hip arthroscopy showed statistical improvement in their WOMAC scores (7 to 2, P arthroscopy showed statistical worsening of the WOMAC (15 to 21, P = .002). Ten (37%) of these 27 patients without a diagnosis failed and needed to be converted to a THR. A significant correlation was found between the collections found on ultrasound (psoas bursa and/or in the hip joint) and the need for synovectomy (P = .01). The overall revision rate to THR after hip resurfacing in our group of patients was 1.3% (n = 13). Female patients were more likely to require postresurfacing hip arthroscopy with 42 (60%) female to only 26 (40%) male patients undergoing this procedure. In our study population, 70% (14/21, P arthroscopy. Hip arthroscopy is a safe surgical treatment option for those patients with a painful hip resurfacing
Full Text Available Developmental dysplasia of the hip (DDH or congenital hip dysplasia (CDH is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DDH, 32.5 years for low dislocation, 31.2 years for high dislocation with a false acetabulum, and 46.4 years for high dislocation without a false acetabulum. Thorough understanding of the bony and soft tissue deformities induced by dysplasia is crucial for the success of total hip arthroplasty. It is important to evaluate the existing acetabular deformity three-dimensionally, and customize the correction in accordance with the quantity and location of ace tabular deficiencies. Acetabular reconstruction in patients with DDH is hallenging. Interpretation of published data is difficult and should be done with caution because most series include patients with different types of hip disease. In general, the complication rate associated with THA is higher in patients with hip dysplasia than it is in patients with osteoarthritis. Overall, clinical and functional outcomes following THA in patients hip dysplasia (DDH differ from those treated for primary hip osteoarthritis, possibly due to the lower age and level of activity. Although function scores decline with age, the scores for pain and range of motion presented with a statistically significant improvement in the long-term.

Summary Background Hip instability has classically been associated with developmental dysplasia of the hip (DDH) in newborns and children. However, numerous factors may contribute to hip instability in children, adolescents, and adults. Purpose This review aims to concisely present the literature on hip instability in patients of all ages in order to guide health care professionals in the appropriate diagnosis and treatment of the various disorders which may contribute to an unstable hip. Methods We reviewed the literature on the diagnosis and surgical management of hip dysplasia and other causes of hip instability. Conclusions Multiple intra- and extra-articular variables may contribute to hip instability, including acetabular bony coverage, femoral torsion, femoroacetabular impingement, and soft tissue laxity. Physical examination and advanced imaging studies are essential to accurately diagnose the pathology contributing to a patient’s unstable hip. Conservative management, including activity modification and physical therapy, may be used as a first-line treatment in patients with intra-articular hip pathology. Patients who continue to experience symptoms of pain or instability should proceed with arthroscopic or open surgical treatment aimed at correcting the underlying pathology. Level of evidence V.

Aim: A proper early diagnosis of aseptic hip necrosis is very important for further therapy.Since there has always been a question of the amount of perfusion in hips at different stages of aseptic hip necrosis we tried to impartially examine the perfusion in hips at early and reversible stages of aseptic hip necrosis. Material and Methods:Study included 143 patients with aseptic hip necrosis.The 550-740 MBq of Tc-99m-DPD were on bolus injected.All patients were subjected to 3-phase scintigraphy of hips and quantitative calculation of relative perfusion in the artery phase (3T) at early and repeated at reversible stages of aseptic hip necrosis. Results: At the early stage of aseptic hip necrosis the obtained 3T was decreased from 0.94-0.69 (3T=0.80).Scintigrams showed a moderate increase or diffuse accumulation. At the reversible stages we obtained 3T decreased from 0.92-0.71 (3T=0.79) thus evidencing hypoperfusion.Scintigrams showed an diffuse increased accumulation. Conclusion: With the aseptic hip necrosis quantitative analysis of perfusion in the artery phase-3T indicates that the perfusion is decreased at all stages of the process which however shows a significantly falling trend with the progress of the disease

Hip palpation has been used to provide semiquantitative information regarding passive joint laxity and susceptibility to hip dysplasia. The purpose of this study was to: (1) evaluate the intra- and inter-examiner repeatability of the hip reduction angle measured at 4 months of age by three examiners using manual goniometry and an electromagnetic tracking system; (2) compare the hip reduction angle measured with manual goniometry to the hip reduction angle measured with the electromagnetic tracking system; and (3) evaluate the hip reduction angle, distraction index and Ortolani manoeuvre at 4 months of age as predictors of the development of hip osteoarthritis at 12 months of age in 11 Labrador Retriever dogs. Intra- and inter-examiner repeatability was demonstrated for both the manual and electromagnetic goniometric measurement of the hip reduction angle (coefficient of variation goniometry was moderately correlated to the hip reduction angle measured by the electromagnetic tracking system (r = 0.603, P goniometry was a poor predictor of osteoarthritis at 12 months of age (r = 0.231, P < 0.062, and r = 0.321, P < 0.01). The distraction index was moderately correlated with the development of osteoarthritis by 12 months of age (r = 0.493, P < 0.0000). The Ortolani sign was sensitive (100%) but not specific (41%) for the development of osteoarthritis at 12 months of age. The hip reduction angle did not further quantify the Ortolani manoeuvre as a predictor of osteoarthritis in Labrador Retrievers.

Core stabilization has been utilized for rehabilitation and prevention of lower limb musculoskeletal injuries. Previous studies showed that activation of the abdominal core muscles enhanced the hip muscle activity in hip extension and abduction exercises. However, the lack of the direct measurement and quantification of the activation level of the abdominal core muscles during the execution of the hip exercises affect the level of evidence to substantiate the proposed application of core exercises to promote training and rehabilitation outcome of the hip region. The aim of the present study was to examine the effects of abdominal core activation, which is monitored directly by surface electromyography (EMG), on hip muscle activation while performing different hip exercises, and to explore whether participant characteristics such as gender, physical activity level and contractile properties of muscles, which is assessed by tensiomyography (TMG), have confounding effect to the activation of hip muscles in enhanced core condition. Surface EMG of bilateral internal obliques (IO), upper gluteus maximus (UGMax), lower gluteus maximus (LGMax), gluteus medius (GMed) and biceps femoris (BF) of dominant leg was recorded in 20 young healthy subjects while performing 3 hip exercises: Clam, side-lying hip abduction (HABD), and prone hip extension (PHE) in 2 conditions: natural core activation (NC) and enhanced core activation (CO). EMG signals normalized to percentage of maximal voluntary isometric contraction (%MVIC) were compared between two core conditions with the threshold of the enhanced abdominal core condition defined as >20%MVIC of IO. Enhanced abdominal core activation has significantly promoted the activation level of GMed in all phases of clam exercise (P recruitment in Clam, HABD and PHE exercises, and this enhancement is correlated with higher physical activity and stiffer hip muscle. Our results suggest the potential application of abdominal core activation for

The aim of this study was to evaluate the impact of dancing on hip joint mobility and to assess the relationship between active movements of the hips and injuries among dancers, which may be important in planning rehabilitation in this group. The sample comprised 49 dancers (37 women and 12 men) aged 15 to 32 years. The participants were the professional dancers of the Kielce Dance Theatre and members of two youth jazz dance teams from the Kielce Dance Theatre. The active range of motion of the hips was measured in three planes using a goniometer in order to assess the influence of dance training on hip joint mobility. A questionnaire-based survey was also conducted. The range of flexion, extension and external rotation was significantly greater in the group of long-time dancers (p <0.05). There was a significantly greater range of flexion, abduction and external rotation in previously injured hip joints (p<0.05). 1. Injuries to hip joints in dancers may result in increased ranges of motion, which may lead to disturbances of joint stability. 2. Being a long-time dancer and the female gender were associated with an increased range of hip joint motion.

Full Text Available Hip fractures often result in serious health implications, particularly in the geriatric population, and have been related to long-term morbidity and death. In most cases, these fractures are caused by impact loads in the area of the greater trochanter, which are produced in a fall. This work is aimed at developing hip protectors using composite materials and evaluating their effectiveness in preventing hip fractures under high impact energy (120 J. The hip protectors were developed with an inner layer of energy absorbing soft material and an outer rigid shell of fiberglass-reinforced polymer composite. According to the experimental results, all tested configurations proved to be effective at reducing the impact load to below the average fracture threshold of proximal femur. Furthermore, an addition of Ethylene Vinyl Acetate (EVA to the impacted area of the composite shell proved to be beneficial to increase impact strength of the hip protectors. Thus, composite hip protectors proved to be a viable alternative for a mechanically efficient and cost-effective solution to prevent hip fractures.

Instability following total hip arthroplasty (THA) is an unfortunately frequent and serious problem that requires thorough evaluation and preoperative planning before surgical intervention. Prevention through optimal index surgery is of great importance, as the management of an unstable THA is challenging even for an experienced joints surgeon. However, even after well-planned surgery, a significant incidence of recurrent instability still exists. Non-operative management is often successful if the components are well-fixed and correctly positioned in the absence of neurocognitive disorders. If conservative management fails, surgical options include revision of malpositioned components; exchange of modular components such as the femoral head and acetabular liner; bipolar arthroplasty; tripolar arthroplasty; use of a larger femoral head; use of a constrained liner; soft tissue reinforcement and advancement of the greater trochanter.

Full Text Available Pathological changes that develop in the hip joints (HJ have different origins and mechanisms of development, but their main manifestation is pain. The nature of this pain cannot be well established on frequent occasions. The English-language medical literature currently classifies such disorders as greater trochanter pain syndrome (GTPS. Its major signs are chronic pain and local palpatory tenderness in the outer part of HJ. The development of GTPS may be associated with inflammation of the synovial bursae situated in the greater tronchanter, as well as with tendinitis, myorrhexis, iliotibial band syndrome, and other local changes in the adjacent tissues or with systemic diseases. So GTPS may be characterized as regional pain syndrome that frequently mimics pain induced by different diseases, including myofascial pain syndrome, osteoarthrosis, spinal diseases, etc.

The use of microsurgery in the management of burn sequelae is not a new idea. According to the properties of various types of free flaps different goals can be achieved or various additional procedures have to be combined. We report the comparison of two different free flaps on a single patient for reconstruction of both upper extremities for burn sequelae. A 1-year-old child sustained severe burns on both hands, arms and thorax and was initially only treated conservatively. This resulted in severe contractures. At the age of 4-years a free gracilis flap was selected for reconstruction of his left hand and a free anterolateral thigh flap for the right hand. We noticed a better functional and esthetic result for the gracilis flap associated with a shorter operative time and a minor donor site morbidity. The intraoperative technique and time, postoperative complications, functional and esthetic results and donor site morbidities were studied in the two types of flaps chosen. A review of literature was also performed. Our experience reported a better success of the gracilis muscle flap covered with a split skin graft compared to the anterolateral thigh flap in the reconstruction of hand function after severe burn sequelae.

Knee flexion contracture (KFC) is a common complication of recurrent hemarthrosis in children and young adults with hemophilia. If the KFC is not prevented (by means of primary prophylaxis) and treated properly and early (be means of physical medicine and rehabilitation), it will become fixed. Areas covered: The aim of this article is to review the potential role of botulinum toxin type A (BTX-A) intramuscular injections for the treatment of KFC in people with hemophilia (PWH). Expert commentary: Although two recent reports have mentioned the benefits of intramuscular injections of BTX-A in PWH with KFC, the data are still scant and too preliminary. The use of intramuscular injections of BTX-A in PWH today should not be recommended until more case studies/small series (ideally well-designed clinical trials) fully demonstrate that this is safe and effective. The risks of intramuscular injections to a hemophilia patient cannot be underestimated (iatrogenic muscle hematomas and pseudotumors). This paper calls the attention of hemophilia treaters on the potential risks of this apparently interesting technique. The current use of BTX-A intramuscular injections in KFC of PWH could make no sense. Raising false expectations in these patients should be avoided.

AIM: determine the influence of the load of the hip joint during professional activity and BMI as risk factors for the hip osteoarthritis. MATERIAL AND METHOD: We analysed 148 patients. Patients were divided into two groups ( I group with osteoarthritis of the hip, II group without osteoarthritis of the hip. In all, performed diagnostic procedure: anamnesis, physical examination (estimate of walking and hip joint movement, laboratory blood test and urine test radiological examination and taking data on the height and weight to calculated BMI. We assessed the data that is related to the load of the hip joint during professional activities (mostly sitting work and mostly standing job with carrying load. Statistical analysis was done using the software package SPSS 14.0, Microsoft Office Word 2003. RESULTS: In the first group, average age was 67.76 years, with females prevailing (67.6%. In this group the larger body mass was noted (81.82 ± 12.18, with statistically significant difference (T-test 2.923, p<0.01; the average BMI was higher the average BMI was higher (30.18 ± 4.6, with statistically significant difference (T-test 3.832, p<0.01. This group had more overweight patients (87.7%,with statistically significant difference (Fisher test, p<0.01. In I group 62,2% of patients were doing hard physical work (standing job with repeated carrying load and we found statistically significant difference between groups (Fisher test p<0,01. CONCLUSION: Patients with osteoarthritis of the hip had a higher body weight, higher BMI. Also we found the influence of hard physical labor at work, and they were performed mostly standing job with carrying load.

Imaging of the hip abductors plays an increasing role for the evaluation of greater trochanteric pain in patients with and without total hip arthroplasty. This review article addresses the anatomy of the hip abductors and their intervening bursae. It highlights different possible imaging appearances such as tendinopathy or partial and full thickness tears of the gluteal tendons. Muscle atrophy or fatty degeneration of the gluteal muscles is an important reason for limping. Inflammatory diseases such as hydroxyapatite crystal deposition disease or spondylarthritis have to be considered. Knowledge of these different entities is important to achieve optimal treatment and outcomes.

PURPOSE: To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). METHODS: 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent uncemented THA using the trident acetabular cup. Obese elderly women at risk of femoral neck fracture and patients with large subchondral pseudocysts or a history of avascular necrosis of the femoral head were assigned to uncemented THA. Acetabular reamings were collected; marginal osteophytes were not included. The reamings were dehydrated, defatted, and weighed. RESULTS: The mean weight of acetabular reamings was not significantly different between patients undergoing hip resurfacing and uncemented THA (p=0.57). CONCLUSION: In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and removal of excessive bone stock.

Background The results of primary total hip arthroplasties (THAs) after pediatric hip diseases such as developmental dysplasia of the hip (DDH), slipped capital femoral epiphysis (SCFE), or Perthes' disease have been reported to be inferior to the results after primary osteoarthritis of the hip (OA.......9%) were operated due to pediatric hip diseases (3.1% for Denmark, 8.8% for Norway, and 1.9% for Sweden) and 288,435 THAs (77.8%) were operated due to OA. Unadjusted 10-year Kaplan-Meier survival of THAs after pediatric hip diseases (94.7% survival) was inferior to that after OA (96.6% survival......). Consequently, an increased risk of revision for hips with a previous pediatric hip disease was seen (risk ratio (RR) 1.4, 95% CI: 1.3-1.5). However, after adjustment for differences in sex and age of the patients, and in fixation of the prostheses, no difference in survival was found (93.6% after pediatric hip...

The number of patients undergoing hip arthroplasty revision is constantly growing. Especially, complex problem is extensive loss of bone stock and pelvic discontinuity that requires reconstruction. The paper presented a 50-year old patient, who ten years ago underwent a total cement artrhroplasty of the left hip. A year after the primary operation the patient had difficulties in walking without crutches. Problems intensified in the last five years, the patient had severe pain, totally limited movement in the left hip and could not walk at all. Radiographically, we found loose femoral component, massive loss of bone stock of proximal femur, acetabular protrusion and a consequent pelvic discontinuity. Clinically, a completely disfunctional left hip joint was registered (Harris hip score--7.1). We performed total rearthroplasty by a custom-made Waldemar Link total hip prosthesis with acetabular antiprotrusio cage and compensation of bone defects with a graft from the bone bank. A year after the operation, we found clinically an extreme improvement in Harris hip score--87.8. Radiographically, we found stability of implanted components, a complete graft integration and bone bridging across the site of pelvic discontinuity. Pelvic discontinuity and massive loss of proximal femoral bone stock is a challenging and complex entity. Conventional prostheses cannot provide an adequate fixation and stability of the hip. Application of custom-made prosthesis (measured specificaly for a patient) and additional alografting bone defects is a good method in revision surgery after unsuccessful hip arthroplasty with extensive bone defects.

Full text: MRI has been shown to gain increasing importance in recent years in the evaluation of disorders of the hip and pelvis. Nowadays, conventional or fast spin echo (T1, Turbo (Fast) T2 (or PD)) MR imaging sequences are used most commonly to examine the hip and pelvis. Three dimensional (3D) gradient echo (GE) imaging allows acquisition of very thin (1 mm) sections. MR imaging with fat suppression technique (STIR, TIRM, FAT SAT T2) represent an effective screening technique for the assessment of fluid, hemorrhage, pus, or tumor in the marrow, joint or soft tissues. These techniques increase the sensitivity for the detection of a variety of pathologic processes. Fat suppression MR imaging, when combined with intravenous (or intraarticular) administration of a gadolinium compound, also is effective and often is employed when evaluating neoplastic or infectious diseases (intravenous injection), abnormalities of articular cartilage or labrum, or possible intraarticular osteocartilaginous bodies (intraarticular injection). A lesion of the acetabular labrum based is one cause of chronic hip pain in patients with developmental dysplasia of the hips, as well as in patients with a history of hip trauma or femoroacetabular impingement. MR imaging and, in particular, MR arthrography, however, have been shown to be highly accurate in the detection of subtle intraarticular abnormalities such as labral lesion. Conventional MR imaging has shown poor accuracy in detecting labral lesions, due to its inability to depict small tears and the difficulty in determining if intralabral signal abnormalities extend to the surface of the labrum. MR arthrography, however has been shown to overcome these difficulties and to have excellent accuracy in detecting labral pathology. As labral abnormalities are believed to be a precursor of osteoarthritis, orthopedic surgeons believe that surgical intervention will be influenced substantially by the type, extension and location of labral
Full Text Available Dislocation of the hip joint in adults is usually caused by high-energy trauma such as road traffic accidents or falls from heights. Posterior dislocation is observed in most cases. However, atraumatic anterior dislocation of the hip joint is extremely rare. We present a case of atraumatic anterior dislocation of the hip joint that was induced by an activity of daily living. The possible causes of this dislocation were anterior capsule insufficiency due to developmental dysplasia of the hip, posterior pelvic tilt following thoracolumbar kyphosis due to vertebral fracture, and acetabular anterior coverage changes by postural factor. Acetabular anterior coverage changes in the sagittal plane were measured using a tomosynthesis imaging system. This system was useful for elucidation of the dislocation mechanism in the present case.

. The questionnaire included questions on patients' perceptions of traction-related problems in the groin area, at the knee and ankle and how patients had coped with these problems. A total of 100 consecutive patients undergoing hip arthroscopy filled out the questionnaire. Primary findings of this study were that 74......% of patients reported some sort of traction-related problems after hip arthroscopy. About 32% of the patients had problems in the groin area and 49% of the patients complained of symptoms in the knee joint. A total of 37% of the patients had experienced problems from the traction boot in the ankle area....... The complications were found to be temporary and disappeared after 2-4 weeks. Five patients still had complaints after 3 months. All five patients had a pre-existing knee injury prior to undergoing hip arthroscopy. Traction-related problems after hip arthroscopy are a challenge and our study showed that 74...

Robotic technology offers technical advantages that might offer new solutions for hip arthroscopy. Two hip arthroscopies were performed in human cadavers using the da Vinci surgical system. During both surgeries, a robotic camera and 5 or 8 mm da Vinci trocars with instruments were inserted into the hip joint for manipulation. Introduction of cameras and working instruments, docking of the robotic system and instrument manipulation was successful in both cases. The long articulating area of 5 mm instruments limited movements inside the joint; an 8 mm instrument with a shorter area of articulation offered an improved range of motion. Hip arthroscopy using the da Vinci standard system appears a feasible alternative to standard arthroscopy. Instruments and method of application must be modified and improved before routine clinical application but further research in this area seems justified, considering the clinical value of such an approach.

A case of hip joint synovial chondromatosis with an unusual scintigraphic pattern is described. This pattern was suggestive of a hip joint destructive reactive articular process or late manifestations of avascular necrosis of the femoral head. Concurrent radiographs were normal, as were laboratory investigations. Follow-up radiographs six months later showed radiolucencies and erosive bone changes in the diseased joint. Surgical and histopathological findings revealed well developed hip synovial chondromatosis (HSC) with thickened synovium and large, loose, cartilaginous bodies occupying and widening the tightened joint space, with destructive secondary juxta articular pressure and bone erosions. This and other scintigraphic patterns in HSC, and the differential diagnosis of the findings in patients with painful hip presentations are discussed.

Full Text Available Osteoporosis is a major health problem, especially in elderly populations, and is associated with fragility fractures at the hip, spine, and wrist. Hip fracture contributes to both morbidity and mortality in the elderly. The demographics of world populations are set to change, with more elderly living in developing countries, and it has been estimated that by 2050 half of hip fractures will occur in Asia. This review conducted using the PubMed database describes the incidence of hip fracture in different regions of the world and discusses the possible causes of this wide geographic variation. The analysis of data from different studies show a wide geographic variation across the world, with higher hip fracture incidence reported from industrialized countries as compared to developing countries. The highest hip fracture rates are seen in North Europe and the US and lowest in Latin America and Africa. Asian countries such as Kuwait, Iran, China, and Hong Kong show intermediate hip fracture rates. There is also a north-south gradient seen in European studies, and more fractures are seen in the north of the US than in the south. The factors responsible of this variation are population demographics (with more elderly living in countries with higher incidence rates and the influence of ethnicity, latitude, and environmental factors. The understanding of this changing geographic variation will help policy makers to develop strategies to reduce the burden of hip fractures in developing countries such as India, which will face the brunt of this problem over the coming decades.

To analyze the effects of metacarpus and phalanx traction on correction of scar contracture of hand after burn on the palm side retrospectively. A total of 32 patients with 39 affected hands with scar contracture on the palm side after burn were hospitalized from May 2010 to December 2014. Method of treatment: scar contracture was conservatively released followed by skin grafting, which was referred to as method A; Kirschner wire was inserted into the middle or distal phalanx of finger with contracture and the corresponding metacarpus in the shape of U for 2 to 7 weeks' traction, which was referred to as method B; traction frame was built based on the traction pile and anchor formed by Kirschner wire inserted through the second to the fifth metacarpus and distal phalanx of finger with contracture, and then the affected fingers were pulled into a straight position with rubber bands for 2 to 6 months, which was referred to as method C. Method A was used in patients who would be treated with thorough release of scar followed by skin grafting routinely. Method B was used in patients who would be treated with intramedullary Kirschner wire fixation after release of scar contracture and skin transplantation routinely. Method C was further used in patients when methods A and B failed to accomplish the expected result. Method C was used in the first place followed by method A in whom there might be vascular decompensation or exposure of tendon and bone after scar release, and those who failed to meet the expectation were treated with method C in addition. Patients who were unwilling to undergo surgery were treated with method C exclusively. During the course of treatment, the presence or absence of infection and slipping of Kirschner wire or its slitting through soft tissue were observed. The presence or absence of tendency of recurrence of scar contracture within 1 to 2 weeks after treatment was observed. The length of palmar skin measuring from the root of finger with

To evaluate the association of preoperative intra-articular hip injection with surgical site infection after hip arthroscopy. A large administrative database was used to identify all patients undergoing hip arthroscopy from 2007 to 2015 within a single private insurer and from 2005 to 2012 within Medicare in the United States. Those that received an ipsilateral preoperative intra-articular hip injection were identified. The patients were then divided into the following groups based on the interval between preoperative injection and ipsilateral hip arthroscopy: (1) 12 months) of preoperative hip injection. Patients developing a surgical site infection within 6 months following hip arthroscopy were identified using International Classification of Diseases, Ninth Revision, and Current Procedural Terminology codes associated with infection. Groups were compared using a multivariate logistic regression analysis to control for age, gender, body mass index, smoking status, alcohol usage, and multiple medical comorbidities including diabetes mellitus, hemodialysis use, inflammatory arthritis, and peripheral vascular disease. In total, 19% of privately insured and 6% of Medicare patients received a hip injection within 12 months of hip arthroscopy. The overall infection rate in privately insured and Medicare patients was 1.19% and 1.10%, respectively. Preoperative hip injection within 3 months of surgery was associated with a significantly higher risk of postoperative infection versus controls (2.16%, odds ratio [OR] 6.1, P arthroscopy increased when preoperative intra-articular hip injections were given within 3 months of surgery.

Scar contracture (SC) is one of the most common complications resulting from major burn injuries. Numerous treatments are currently available but they do not always yield excellent therapeutic results. Recent reports suggest that botulinum toxin type A (BTXA) is effective at reducing SC clinically, but the molecular mechanism for this action is unknown. α-Smooth muscle actin (α-SMA) and myosin II are the main components of stress fibers, which are the contractile structures of fibroblasts. The effects of BTXA on α-SMA and myosin II in SC are still unknown. This study aimed to explore the effect of BTXA on α-SMA and myosin II expression in fibroblasts derived from SC and to elucidate its actual mechanism further. Fibroblasts were isolated from tissue specimens of SC. Fibroblasts were cultured in Dulbecco modified Eagle medium with different concentrations of BTXA and their proliferation was analyzed through the tetrazolium-based colorimetric method at 1, 4, and 7 days. Proteins of α-SMA and myosin II were checked using Western blot in fibroblasts treated with different concentrations of BTXA at 1, 4, and 7 days. Fibroblasts without BTXA treatment had a higher proliferation than that in other groups, which indicated that the proliferation of fibroblasts was significantly inhibited by BTXA (P < 0.05). Proteins of α-SMA and myosin II between fibroblasts with BTXA and fibroblasts without BTXA are statistically significant (P < 0.05). These results suggest that BTXA effectively inhibited the growth of fibroblasts derived from SC and reduced the expression of α-SMA and myosin II, which provided theoretical support for the application of BTXA to control SC.

Knee flexion contractures (KFC) are limitations in the ability to fully extend the knee joint. In people with knee osteoarthritis (OA), KFC are common, impair function, and worsen outcomes after arthroplasty. In KFC, the posterior knee capsule is believed to play a key role, but the pathophysiology remains poorly understood. We sought to identify gene expression differences in the posterior knee capsule of patients with OA with and without KFC. Capsule tissue was obtained from the knees of 12 subjects diagnosed with advanced-stage OA at the time of knee arthroplasty surgery. The presence or absence of KFC allocated patients into 2 groups using a case-control design. Genomewide capsular gene expression was compared between the 2 patient groups. Confirmation of differential expression of the corresponding proteins was performed by immunohistochemistry on tissue sections. There were no significant demographic differences between the patients with OA with KFC and without KFC save for reduced extension in their surgical knee (pKFC patients showed a 6.4-fold decrease in CSN1S1 (p=0.017) gene expression and a 3.7-, 2.0-, and 2.6-fold increase in CHAD, Sox9, and Cyr61 gene expression, respectively (p=0.001, 0.004, 0.001, respectively). There were corresponding increases in protein levels for chondroadherin, sex determining region Y-box 9, and casein alphaS1 (all pKFC exhibited differential expression of 4 genes all previously documented to be associated with tissue fibrosis.

Development of pressure sores during hospital admission causes morbidity and distress to the patient, increases strain on nursing resources, delaying discharge and possibly increasing mortality. A hip fracture in elderly patients is a known high-risk factor for development of pressure sores. We aimed to determine the current incidence of pressure sores and identify those factors which were associated with an increased risk of pressure sores. We retrospectively analysed prospectively collected data of 4654 consecutive patients admitted to a single unit. One hundred and seventy-eight (3.8%) of our patients developed pressure sores. Patient factors that increased the risk of pressure sores were increased age, diabetes mellitus, a lower mental test score, a lower mobility score, a higher ASA score, lower admission haemoglobin and an intra-operative drop in blood pressure. The risk was higher in patients with an extracapsular neck of femur fracture and patients with an increased time interval between admission to hospital and surgery. Our studies indicate that while co-morbidities constitute a substantial risk in an elderly population, the increase in incidence of pressure sores can be reduced by minimising delays to surgery.

Acrylic-fixed total hip and surface replacement arthroplasty have been very effective in affording immediate relief of pain and providing improved function. Complications have been reduced by improvements in design, materials, and especially technique. They are now very low in the elderly, and the stem type acrylic-fixed design remains the procedure of choice. The failure rates in youthful patients and those with bone-stock deficiencies have been high in both THR and surface types, although the latter had the advantage of preserving femoral stock. On the femoral side, the new "macro" femoral designs from Europe and "micro" femoral porous designs have shown promise, but thigh pain, incomplete and difficult to predict bone ingrowth patterns, coupled with removal problems have influenced design and technique changes. Both press-fit stem types and porous surface replacements have produced promising initial results with less potential downside risks. On the acetabular side, both the cementless hemispherical with screw-type adjuvant fixation, or the chamfered cylinder designs, used primarily with the UCLA porous surface replacements, but also with stem-type devices, appear to achieve best short-term results, while the entire variety of screw rings are disappointing. The future will bring further refinements in technique and specific indications for certain types of replacement stem in specific types of bone stock deficiencies. The all ceramic-ceramic and ceramic-polyethylene bearings show promise of reducing wear and, hence, should improve longevity of implant fixation.

The conversion of previous hip surgery to total hip arthroplasty creates a durable construct that is anatomically accurate. Most femoral components with either cemented or cementless design have a fixed tapered proximal shape. The proximal femoral anatomy is changed due to previous hip surgery for fixation of an intertrochanteric hip fracture, proximal femoral osteotomy, or a fibular allograft for avascular necrosis. The modular S-ROM (DePuy Orthopaedics Inc., Warsaw, Ind) hip stem accommodates these issues and independently prepares the proximal and distal portion of the femur. In preparation and implantation, the S-ROM hip stem creates less hoop stresses on potentially fragile stress risers from screws and thin bone. The S-ROM hip stem also prepares a previously distorted anatomy by milling through cortical bone that can occlude the femoral medullar canals and recreate proper femoral anteversion and reduces the risk of intraoperative or postoperative periprosthetic fracture due to the flexible titanium-slotted stem. The S-ROM femoral stem is recommended for challenging total hip reconstructions.

Full Text Available Background: Hip osteoarthritis typically manifests with groin or thigh pain. Other atypical pain patterns, including knee pain, have been described. Except for 2 case reports, there is no literature on this subject. Methods: From our institutional database, between 2011 and 2016, we identified 21 patients who were referred for treatment of knee pain but ultimately diagnosed with hip pathology as the cause of their pain. This group was evaluated for duration of symptoms prior to diagnosis, previous interventions, presence of walking aids, and symptom resolution after treatment of the hip pathology. Results: Fifteen of the 21 patients were referred from musculoskeletal providers (12 from orthopaedic surgeons. Prior to diagnosis of the hip etiology, 16 patients were reduced to major assistive devices including wheelchairs. Twelve of 21 patients had undergone surgical knee interventions, including total knee arthroplasty, with minimal to no relief of their pain. Seventeen of 21 referred patients underwent total hip arthroplasty at our institution. Fourteen patients had complete resolution of knee pain after total hip arthroplasty. Conclusions: Although knee pain referred from hip disease may be considered a basic and common knowledge, it continues to be an overlooked phenomenon. Most of the cases were misdiagnosed by musculoskeletal providers including orthopaedic surgeons and this highlights the need for continued education and awareness of this clinical scenario.

OBJECTIVES: To compare the hip and ankle range of motion and hip muscle strength in 8-11 year old novice female ballet dancers and controls. METHODS: Subjects were 77 dancers and 49 controls (mean (SD) age 9.6 (0.8) and 9.6 (0.7) years respectively). Supine right active hip external rotation (ER) and internal rotation (IR) were measured using an inclinometer. A turnout protractor was used to assess standing active turnout range. The measure of ER achieved from below the hip during turnout (non-hip ER) was calculated by subtracting hip ER range from turnout range, and hip ER:IR was derived by dividing ER range by IR range. Range of right weight bearing ankle dorsiflexion was measured in a standing lunge using two methods: the distance from the foot to the wall (in centimetres) and the angle of the shank to the vertical via an inclinometer (in degrees). Right calf muscle range was measured in weight bearing using an inclinometer. A manual muscle tester was used to assess right isometric hip flexor, internal rotator, external rotator, abductor, and adductor strength. RESULTS: Dancers had less ER (pballetic training.

Study Design Cross-sectional study. Background The Hip Stability Isometric Test (HipSIT) evaluates the strength of the hip posterolateral stabilizers in a position that favors greater activation of the gluteus maximus and gluteus medius and lower activation of the tensor fascia lata. Objectives To check the validity and reliability of the HipSIT and to evaluate the HipSIT in women with patellofemoral pain (PFP). Methods The HipSIT was evaluated with a handheld dynamometer. During testing, the participants were sidelying, with their legs positioned at 45° of hip flexion and 90° of knee flexion. Participants were instructed to raise the knee of the upper leg while keeping the upper and lower heels in contact. To establish reliability and validity, 49 women were tested with the HipSIT by 2 different evaluators on day 1, and then again 7 days later. The strength of the hip extensors, abductors, and external rotators was also evaluated. Twenty women with unilateral PFP were also evaluated. Results The HipSIT has excellent intrarater and interrater reliability. The standard error of measurement was 0.01 kgf/kg, and the minimal detectable change was 0.036 kgf/kg. The HipSIT showed good validity in isolated hip abduction, external rotation, and extension (Pstrength deficits in women with PFP. J Orthop Sports Phys Ther 2017;47(12):906-913.

To explore the solution of choosing the minimally invasive incision site for gluteal muscle contracture patient based on standard injection point of gluteal muscle. from September 2008 to August 2010, 25 patients (14 males and 11 females with an average of 16.5 years, ranging from 12 to 26 years) with injected gluteal muscle contracture were prospectively studied. The course of disease was from 6 to 12 years. Firstly, the connective skin Surface line from anterior superior iliac spine to coccyx (line AD) was delineated and the point (point O) was marked out as the standard gluteal muscle injection site which was on the one-third of the distance from the anterior superior iliac spine(point A) to the coccyx (point D). Secondly, the anterior and posterior edge lines of surface projection of the gluteal muscle contracture banding (line a, line p) were delineated. Thirdly, the distance from B to O and C to O (B is the point of intersection of line a and line AD,C is the point of intersection of line P and line AD)were measured which was the intersection of line a,p and line AD to point O. Lastly, the minimally invasive surgery was operformed via the skin entry of point C. OB = (0 +/- 0.76) cm, OC = (2.86 +/- 0.78) cm, BC = (2.86 +/- 1.01) cm,the mean postoperative drainage was less than 10 ml,there was no nerve damage,hematoma and other complications. All patients achieved the function of squatting in 4 to 6 days. The solution of choosing the minimally invasive incision site based on standard injection point of gluteal muscle has advantages of positioning precisely,handling easily, recoverying quickly, less trauma and safety, etc.

Muscle stiffness and joint contractures are currently regarded as the most common complications of limb lengthening. To better understand the mechanisms of joint contractures, architectural changes of all involved muscles were analyzed in 9 goats after 20% tibial lengthening with standard distraction protocol.All 13 muscles of the goat's tibia were found to be organized into an anterior compartment with 2 longitudinal and 4 pennate muscles and a posterior compartment with 1 longitudinal and 6 pennate muscles. Longitudinal muscles showed better compliance to distraction than pinnate muscles. Although muscle-to-bone lengthening ratio ranged widely (0-1.2), most of the muscles and especially those located in the posterior compartment showed much less lengthening than the bone. Muscular portions of the muscles lengthened more substantially (average, 17%) than their associated tendons (average, 7%). Muscle fiber length changes varied greatly between muscles (range, 0%-88%). Normalization of muscle fiber length revealed considerable elongation of anterior muscles fibers (25%) that was associated with an addition of new sarcomeres in series. Fiber length increase of all posterior muscles but one occurred by stretching of existing sarcomeres, with little addition or even dissolution of sarcomeres in series. This correlated with muscle mass changes showing significant muscle atrophy in the posterior compartment and better mass preservation in the anterior compartment.The study revealed striking difference in response to limb lengthening between individual muscles and muscles from antagonistic compartments in particular. Poor sarcomerogenesis in the posterior muscles leading to their insufficient length increase seems to play major role in the development of joint contractures.

An internal rotation contracture of the shoulder is common after neonatal brachial plexus injuries due to subscapularis shortening and atrophy. It has been explained by 2 theories: muscle denervation and muscle imbalance between the internal and external rotators of the shoulder. The goal of this study was to test the hypothesis that muscle imbalance alone could cause subscapularis changes and shoulder contracture. We performed selective neurectomy of the suprascapular nerve in 15 newborn rats to denervate only the supraspinatus and the infraspinatus muscles, leaving the subscapularis muscle intact. After 4 weeks, passive shoulder external rotation was measured and a 7.2-T magnetic resonance imaging scan of the shoulders was used to determine changes in the infraspinatus and subscapularis muscles. The subscapularis muscle was weighed to determine the degree of mass loss. An additional group of 10 newborn rats was evaluated to determine the sectional muscle fiber size and muscle area of fibrosis by use of images from type I collagen immunostaining. There was a significant decrease in passive shoulder external rotation, with a mean loss of 66°; in the thickness of the denervated infraspinatus, with a mean loss of 40%; and in the thickness and weight of the non-denervated subscapularis, with mean losses of 28% and 25%, respectively. No differences were found in subscapularis muscle fiber size and area of fibrosis between shoulders after suprascapular nerve injury. Our study supports the theory that shoulder muscle imbalance is a cause of shoulder contracture in patients with neonatal brachial plexus palsy.

Full Text Available Purpose: The objective of the study was to compare the performance of i-gel supraglottic airway with cLMA in difficult airway management in post burn neck contracture patients and assess the feasibility of i-gel use for emergency airway management in difficult airway situation with reduced neck movement and limited mouth opening. Methods: Prospective, crossover, randomized controlled trial was performed amongst forty eight post burn neck contracture patients with limited mouth opening and neck movement. i-gel and cLMA were placed in random order in each patient. Primary outcome was overall success rate. Other measurements were time to successful ventilation, airway leak pressure, fiberoptic glottic view, visualization of square wave pattern. Results: Success rate for the i-gel was 91.7% versus 79.2% for the cLMA. i-gel required shorter insertion time (19.3 seconds vs. 23.5 seconds, P=0.000. Airway leak pressure difference was statistically significant (i-gel 21.2 cm H20; cLMA 16.9 cm H 2 0; P=0.00. Fiberoptic view through the i-gel showed there were less epiglottic downfolding and better fiberoptic view of the glottis than cLMA. Overall agreement in insertion outcome for i-gel was 22/24 (91.7% successes and 2/24(8.3% failure and for cLMA, 19/24 (79.16% successes and 5/24 (16.7% failure in the first attempt. Conclusion: The i-gel is cheap, effective airway device which is easier to insert and has better clinical performance in the difficult airway management of the airway in the post burn contracture of the neck. Our study shows that i-gel is feasible for emergency airway management in difficult airway situation with reduced neck movement and limited mouth opening in post burn neck.

Metal-on-metal (MoM) hip arthroplasties have been utilised over the last 15 years to restore hip function for 1.5 million patients worldwide. Althoug widely used, this hip arthroplasty releases metal wear debris which lead to muscle atrophy. The degree of muscle wastage differs across patients ranging from mild to severe. The longterm outcomes for patients with MoM hip arthroplasty are reduced for increasing degrees of muscle atrophy, highlighting the need to automatically segment pathological muscles. The automated segmentation of pathological soft tissues is challenging as these lack distinct boundaries and morphologically differ across subjects. As a result, there is no method reported in the literature which has been successfully applied to automatically segment pathological muscles. We propose the first automated framework to delineate severely atrophied muscles by applying a novel automated segmentation propagation framework to patients with MoM hip arthroplasty. The proposed algorithm was used to automatically quantify muscle wastage in these patients.

The aim of the present study is to analyze the incidence of hip fracture as a complication of admissions to internal medicine units in Spain. We analyzed the clinical data of 2,134,363 adults who had been admitted to internal medicine wards. The main outcome was a diagnosis of hip fracture during hospitalization.Outcome measures included rates of in-hospital fractures, length of stay and cost. A total of 1127 (0.057%) admittances were coded with an in-hospital hip fracture. In hospital mortality rate was 27.9% vs 9.4%; p patients with a hip fracture (20.7 days vs 9.8 days; p hip-fracture patients (6927€ per hospitalization vs 3730€ in non fracture patients). Risk factors related to fracture were: increasing age by 10 years increments (OR 2.32 95% CI 2.11-2.56), female gender (OR 1.22 95% CI 1.08-1.37), admission from nursing home (OR 1.65 95% CI 1.27-2.12), dementia (1.55 OR 95% CI1.30-1.84), malnutrition (OR 2.50 95% CI 1.88-3.32), delirium (OR 1.57 95% CI 1.16-2.14), and anemia (OR 1.30 95%CI 1.12-1.49). In-hospital hip fracture notably increased mortality during hospitalization, doubling the mean length of stay and mean cost of admission. These are reasons enough to stress the importance of designing and applying multidisciplinary plans focused on reducing the incidence of hip fractures in hospitalized patients.

To explore clinical efficacy of hip replacement for hip-joint diseases with Parkinson disease. From December 2011 to December 2016, 18 patients with hip-joint diseases with Parkinson disease treated by hip replacement, including 8 males and 10 females aged from 59 to 87 years old with an average of 71 years old. Among them, 3 cases were developmental dysplasia of hip, 3 cases were femoral head necrosis and 12 cases were femoral neck fracture. All patients manifested with obvious pain and limitation of stepping ability. Postoperative complications were observed and Harris score were used to compare hip joint function after operation. The incision were healed well, and pain were alleviated or disappeared, and hip joint function were improved. Eighteen patients were followed up from 1 to 3 years with an average of 2.3 years. At the latest follow up, 14 cases recovered freedom-walk, 2 cases could walk with walking stick, 1 case could walk with walking aid and 1 case was died. Among 18 patients, 2 cases were occurred dislocation, and 1 case were died for cardiac disease at 3 months after operation. Four patients were occurred slight pain. There were significant differences in Harris scores among preoperative (41.7±1.4), 6 months after operation(80.1±5.4) and the final follow-up (83.4±2.1), and 10 cases got excellent result, 4 good, 1 fair and 2 poor. Application of hip replacement for hip-joint diseases with Parkinson disease is a safe and effective clinical therapy, and has advantages of less complications and rapid recovery of hip joint function.
Full Text Available Hip joint instability and impingement are the most common biomechanical risk factors that put the hip joint at risk to develop premature osteoarthritis. Several surgical procedures like periacetabular osteotomy for hip dysplasia or hip arthroscopy or safe surgical hip dislocation for femoroacetabular impingement aim at restoring the hip anatomy. However, the success of joint preserving surgical procedures is limited by the amount of pre-existing cartilage damage. Biochemically sensitive MRI techniques like delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC might help to monitor the effect of surgical or non-surgical procedures in the effort to halt or even reverse joint damage.

The study of acetabular morphology has shown that there are geographic differences in the morphology and prevalence of acetabular dysplasia among different ethnic groups. However, few data exist on the shape of the acetabulum in various populations around the world. In this study, we examined samples of pelvic radiographs from Egyptian adults. Acetabular dysplasia in adults is characterized by a shallow and relatively vertical acetabulum.The aim of this study was to examine acetabular morphology to determine the prevalence of hip dysplasia in adult Egyptians. This included 244 adults, 134 men and 110 women between 18 and 60 years, who were used to measure center edge angle, acetabular Sharp angle, acetabular head index on anteroposterior radiographic views of the hip joints, and vertical center anterior margin angle on false profile views. The radiographs were taken of patients with no hip complaints at Tanta University Hospital.The results were statistically studied according to the age, height, and weight of patients. The prevalence of acetabular dysplasia was 2.25% for Egyptian men and 3.6% for women with respect to center edge angles, vertical center anterior margin angle, and acetabular head index.We concluded that gender variations in the morphology of the acetabulum and sex influences geometrical measurements of the acetabulum. Egyptian women were more dysplastic than men using the 4 parameters of hip measurements. There are also racial variations in hip morphology. Copyright 2011, SLACK Incorporated.

This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments. PMID:26495246

Hip fracture in the elderly often occurs in patients with high co-morbidity. Effective management requires a comprehensive and multidisciplinary approach. To evaluate the effect of a quality improvement intervention in the detection and treatment of complications in elderly patients admitted for hip fracture. A comparative study was conducted between two groups of patients admitted for hip fracture prior to 2010, and after a quality improvement intervention in 2013. The intervention consisted of implementing improved multidisciplinary measures in accordance with recent scientific evidence. The degree of compliance of the implemented measures was quantified. Patients admitted due to hip fracture in 2010 (216 patients) and 2013 (196 patients) were similar in age, sex, Barthel Index, and a reduced Charlson Index, although there were more comorbidities in 2013. After implementation of the protocols, the detection of delirium, malnutrition, anemia, and electrolyte disturbances increased. A larger number of patients in 2013 were precribed intravenous iron (24% more) and osteoporosis treatment (61.3% more). The average stay was reduced by 45.3% and surgical delay by 29.4%, achieving better functional efficiency. The implementation of a clinical pathway in geriatric patients with hip fracture is useful to detect and treat complications at an early stage, and to reduce pre-operative and overall stay, all without a negative clinical or functional impact.

To detail our early experience using concomitant hip arthroscopy and periacetabular osteotomy (PAO) for the treatment of acetabular dysplasia. We prospectively collected and retrospectively reviewed the surgical and outcome data of 17 patients who underwent concomitant hip arthroscopy and PAO between October 2010 and July 2013. Preoperative and postoperative range of motion, outcome and pain scores, and radiographic data were collected. Intraoperative arthroscopic findings and postoperative complications were recorded. The group consisted of 3 male and 14 female patients with a mean follow-up period of 2.4 years. Three patients had undergone previous surgery on the affected hip. Chondrolabral pathology was identified in all 17 patients. Twelve patients underwent labral repair, and five patients underwent partial labral debridement. No patient was converted to total hip arthroplasty or required revision surgery at short-term follow-up. All 4 patient-reported outcome scores showed statistically significant changes from baseline to latest follow-up (P arthroscopy and PAO has been favorable. We noted that all our patients have evidence of chondrolabral damage at the time of PAO when the joint is distracted and evaluated. All patients in this series had intra-articular pathology treated arthroscopically and showed satisfactory mean clinical improvement. Hip arthroscopy with PAO did not appear to introduce complications beyond the PAO alone. Level IV, therapeutic case series. Copyright © 2015 Arthroscopy Association of North America.

To discuss the clinical significance of the most common hip and groin injuries in baseball players, as well as an algorithmic approach to diagnosis and treatment of these injuries. (a) Limitations in throwing velocity, pitch control, and bat swing speed may be secondary to decreased mobility and strength within the proximal kinetic chain, which must harness power from the lower extremities and core. (b) Approximately 5.5% of all baseball injuries per year involve the hip/groin and may lead to a significant amount of time spent on the disabled list. Injuries involving the hip and groin are relatively common in baseball players. Our knowledge of the mechanics of overhead throwing continues to evolve, as does our understanding of the contribution of power from the lower extremities and core. It is paramount that the team physician be able to accurately diagnose and treat injuries involving the hip/groin, as they may lead to significant disability and inability to return to elite levels of play. This review focuses on hip- and groin-related injuries in the baseball player, including femoroacetabular impingement, core muscle injury, and osteitis pubis.
Although the prevalence of (idiopathic) congenital dislocation of the hip (CDH) within the Member States of the European Community is not exactly known, it must be considered as a major problem of public health care and protection. By assessment of available data one can assume that between 1 and 2% of all newborns have dislocation or instability of one or both hips. There is a female predominance of 4:1 and some risk factors are known. The reasons of a higher prevalence in some areas are not yet well understood. Most of instable hips will spontaneously become stable within the first days or weeks of life. However, a considerable number of infants (less than 1%) will remain with instable hips which may dislocate. Dislocation either present at birth or as a result of persistent instability leads to subsequent hip deformation. This is a serious event for each affected individual, and is a heavy load on health care and social costs for the public. Treatment of CDH is easy and usually effective when started early, i.e. before the fourth month of life. The earlier treatment is started the easier, shorter, safer and less expensive it is and its impairment on child development and mother-child interaction can be held to a minimum. Screening for CDH is therefore the most important part of health protection in early infancy. However, this paper concludes that neither sonography nor X-ray examinations are appropriate for CDH screening

The purpose of this study was to document and compare the incidence of intra-articular hip pathologic findings identified using arthroscopy versus conventional imaging in patients with acute trauma to the hip. This was a blinded prospective case series study designed to review the incidence of intra-articular pathologic disorders in patients with post-traumatic injury between the ages of 18 and 65 years who were referred to a single surgeon. Injuries included hip dislocation, proximal femur fracture, pelvic ring fracture, acetabular fracture, penetrating injury (gunshot wound), and soft tissue injury. Preoperative radiographs, computed tomographic (CT) scans, or magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) scans (or a combination of these) were obtained. Findings were documented and compared with intraoperative findings. A total of 29 post-traumatic hips were enrolled in this study. Hip arthroscopy identified 17 of 29 hips (59%) as having loose bodies, 11 of 29 (38%) hips as having an intra-articular step deformity, 14 of 29 (49%) hips as having an osteochondral lesion, and 27 of 29 (93%) hips as having a labral tear. Plain radiographs and CT scans yielded low sensitivity when compared with arthroscopy for the identification of loose bodies and step deformities. MRI/MRA comparison with arthroscopic findings suggest that MRI/MRA is an accurate tool for identification of labral tears, because 91% of tears seen on arthroscopy were also identified by MRI/MRA. In 4 hips, however, MRI/MRA failed to identify osteochondral lesions that were subsequently identified by arthroscopy. Traumatic injuries of the hip result in substantial intra-articular pathologic findings, including loose bodies, labral tears, step deformities, and osteochondral lesions. The arthroscope is a powerful tool in identifying these injuries. Plain radiographs and CT scans appear to underestimate the true incidence of loose bodies and step deformities within the joint when

Purpose Examination of the hip provides information regarding risk for pre-arthritic hip disorders, knee injuries, and low back pain. The purpose of this study was to report a hip screening examination of asymptomatic female soccer athletes and to test the hypothesis that these findings vary by competition experience. Methods Asymptomatic females from a youth soccer club, a college, and a professional team were evaluated. Passive hip range of motion, hip abduction strength, and hip provocative tests were assessed. Data were compared for the grade/middle school, high school, college, and professional athletes. Results One hundred and seventy-two athletes with a mean age of 16.7 ± 5 years (range 10–30) participated. Professional athletes had less flexion (HF) for both hips (p hips as compared to all other groups (p hip abduction strength as compared to other groups (p hip tests were found in 22 % of all players and 36 % of the professionals. In professionals, a positive provocative test was associated with ipsilateral decreased HF (p = 0.04). Conclusion Asymptomatic elite female soccer athletes with the most competition experience had less bilateral hip flexion and preferred kicking leg IR than less-experienced athletes. Positive provocative hip tests were found in 22 % of athletes. Future studies are needed to show whether these findings link to risk for intra-articular hip or lumbar spine and knee disorders.

Full Text Available Abstract Objective To assess the incidence of total hip arthroplasty (THA in osteoarthritic patients who were treated by arthroscopic debridement and to evaluate factors that might influence the time interval from the first hip arthroscopy to THA. Design Retrospective clinical series Methods Follow-up data and surgical reports were retrieved from 564 records of osteoarthritic patients that have had hip arthroscopy between the years 2002 to 2009 with a mean follow-up time of 3.2 years (range, 1-6.4 years. The time interval between the first hip arthroscopy to THA was modelled as a function of patient age; level of cartilage damage; procedures performed and repeated arthroscopies with the use of multivariate regression analysis. Results Ninety (16% of all participants eventually required THA. The awaiting time from the first arthroscopy to a hip replacement was found to be longer in patients younger than 55 years and in a milder osteoarthritic stage. Patients that experienced repeated hip scopes had a longer time to THA than those with only a single procedure. Procedures performed concomitant with debridement and lavage did not affect the time interval to THA. Conclusions In our series of arthroscopic treatment of hip osteoarthritis, 16% required THA over a period of 7 years. Factors that influence the time to arthroplasty were age, degree of osteoarthritis and recurrent procedures.

Full Text Available The purpose of the study was to analyze the medium- and long-term results of hip arthroplasty using Paavilainen technique in patients with the congenitally dislocated hip. Methods: From 2001 to 2012 180 operations were carried out were using the Paavilainen technique in 140 patients with high dislocation of the hip (Crowe IV. All patients were clinically evaluated using the Harris Hip Score (HHS, VAS and radiography. Statistical analysis was performed using the Pearson correlation coefficients, multiple regression analysis and classification trees analysis. Results: The average Harris score improved from preoperative 41.6 (40,3-43,5 to 79.3 (77,9-82,7 at final follow-up, and the difference was significant. Early complications were 9% (the most frequent were fractures of the proximal femur, later - 16.7% (pseudoarthrosis of the greater trochanter, 13.9%; disclocations-1,1%, aseptic loosening of the components - 1.7%, reoperation performed in 8.3% of cases. Such factors as age and limb length has statistically significant effect on functional outcomes. Established predictive model allows to get the best possible functional outcome in such patients with severe dysplasia. Conclusions: Total Hip arthroplasty using the Paavilainen technique is an effective method of surgical treatment in patients with the congenitally dislocated hip, but it is technically difficult operation with a high incidence of complications in comparison with standard primary total hip replacement.

The wear in hip implants is one of the main causes for premature hip replacements. The wear affects the potential life of the prosthesis and subsequent removals of in vivo implants. Therefore, the objective of this article is to review various joints that show lower wear rates and consequently higher life. Ceramics are used in hip implants and have been found to produce lower wear rates. This article discusses the advantages and disadvantages of ceramics compared to other implant materials. Different types of ceramics that are being used are reviewed in terms of the wear characteristics, debris released, and their size together with other biological factors. In general, the wear rates in ceramics were lower than that of metal-on-metal and metal-on-polyethylene combinations.

Objective of this study was to present the spectrum of early magnetic resonance imaging (MRI) findings following traumatic dislocation of the femoral head, and to identify any associated injuries. Prospective MRI of both hips was performed on 18 patients within 5 weeks of a traumatic femoral head dislocation. The interval between the time of injury and the imaging studies ranged from 2 to 35 days. Posterior dislocation was present in 14 patients and anterior dislocation in 4 patients. In the majority of cases, we performed axial T1, coronal T1, and coronal T2 * (MPGR) sequences. MRI can effectively identify and quantify the muscle injury and joint effusion that invariably accompany traumatic hip dislocations. It is also useful for demonstrating trabecular bone contusion (trabecular injury) and iliofemoral ligament injury, which occur commonly with acute hip dislocation. (orig./VHE)

The benefit of HIP techniques applied to the fabrication of fusion internal components for higher performances, reliability and cost savings are emphasized. To demonstrate the potential of the techniques, design of new blankets concepts and mock-ups fabrication are currently performed by CEA. A coiled tube concept that allows cooling arrangement flexibility, strong reduction of the machining and number of welds is proposed for ITER IAM. Medium size mock-ups according to the WCLL breeding blanket concept have been manufactured. The fabrication of a large size mock-up is under progress. These activities are supported by numerical calculations to predict the deformations of the parts during HIP'ing. Finally, several HIP techniques issues have been identified and are discussed

Full Text Available Osteoblastoma occurring in the region of the hip is very rare, and vague symptoms with uncharacteristic radiographic features often lead to misdiagnosis. Because of radiographic and histological similarities, it must be carefully distinguished from osteoid osteoma, aneurysmal bone cyst, giant cell tumor, and osteosarcoma. Computed tomography is the preferred imaging modality as it is able to detect the nidus and images will not exhibit the flare phenomenon caused by surrounding inflammation seen with magnetic resonance imaging. For hip joint lesions in weight-bearing areas, intralesional curettage may achieve satisfactory outcomes as compared with wide resection. We herein report two cases of osteoblastoma in the hip region in which diagnosis was delayed that were successfully treated with curettage and followed by high-speed burring.

Hip arthroscopy has gained popularity among the orthopedic community and a precise assessment of indications, techniques and results is constantly brought on. In this chapter the principal standard entry portals for central and peripheral compartment are discussed. The description starts from the superficial landmarks for portals placement and continues with the deep layers. For each entry point an illustration of the main structures encountered is provided and the principal structures at risk for different portals are accurately examined. Articular anatomical description is carried out from the arthroscope point of view and sub-divided into central and peripheral compartment. The two compartments are systematically analyzed and the accessible articular areas for each portal explained. Moreover, some anatomical variations that can be found in the normal hip are reported. The anatomical knowledge of the hip joint along with a precise notion of the structures encountered with the arthroscope is an essential requirement for a secure and successful surgery.

Snapping hip syndrome has been described as a hip pain accompanied by an audible snapping during motion of the hip or while walking. The variable causes of its external, internal, and intra-articular origins have been described. The most common extemal snapping hip has been associated with a thickened posterior border of the iliotibial band or of the anterior border of the gluteus maximus muscle slipping over the greater trochanter. The aim of this study was to evaluate the dynamic ultrasound findings of external snapping hip syndrome with review of the literature. We studied 5 patients (7 cases) with external snapping hip and pain over the greater trochanter during walking or hip motion (3 males and 2 females, age range, 14-32 years; mean, 19 years). Two patients reported bilateral snapping hips.

We assessed the role of subscapularis muscle denervation in the development of shoulder internal rotation contracture in neonatal brachial plexus injury. Seventeen newborn rats underwent selective denervation of the subscapular muscle. The rats were evaluated at weekly intervals to measure passive shoulder external rotation. After 4 weeks, the animals were euthanized. The subscapularis thickness was measured using 7.2T MRI axial images. The subscapularis muscle was then studied grossly, and its mass was registered. The fiber area and the area of fibrosis were measured using collagen-I inmunostained muscle sections. Significant progressive decrease in passive shoulder external rotation was noted with a mean loss of 58° at four weeks. A significant decrease in thickness and mass of the subscapularis muscles in the involved shoulders was also found with a mean loss of 69%. Subscapularis muscle fiber size decreased significantly, while the area of fibrosis remained unchanged. Our study shows that subscapularis denervation, per se, could explain shoulder contracture after neonatal brachial plexus injury, though its relevance compared to other pathogenic factors needs further investigation. © 2014 Orthopaedic Research Society.

Full Text Available CONTEXT: Rehabilitation following hip arthroscopy is an integral component of the clinical outcome of the procedure. Given the increase in quantity, complexity, and diversity of procedures performed, a need exists to define the role of rehabilitation following hip arthroscopy.OBJECTIVES: 1 To determine the current rehabilitation protocols utilized following hip arthroscopy in the current literature, 2 to determine if clinical outcomes are significantly different based on different post-operative rehabilitation protocols; and 3 to propose the best-available evidence-based rehabilitation program following hip arthroscopy.DATA SOURCES: Per PRISMA guidelines and checklist, Medline, SciVerse Scopus, SportDiscus, and Cochrane Central Register of Controlled Trials were searched.STUDY SELECTION: Level I-IV evidence clinical studies with minimum two-year follow-up reporting outcomes of hip arthroscopy with post-operative rehabilitation protocols described were included. DATA EXTRACTION: All study, subject, and surgery parameters were collected. All elements of rehabilitation were extracted and analyzed. Descriptive statistics were calculated. Study methodological quality was analyzed using the Modified Coleman Methodology Score (MCMS.RESULTS: 18 studies were included (2,092 subjects; 52% male, mean age 35.1 +/- 10.6 years, mean follow-up 3.2 +/- 1.0 years. Labral tear and femoroacetabular impingement were the most common diagnoses treated and labral debridement and femoral/acetabular osteochondroplasty the most common surgical techniques performed. Rehabilitation protocol parameters (weight-bearing, motion, strengthening, and return-to-sport were poorly reported. Differences in clinical outcomes were unable to be assessed given heterogeneity in study reporting.

The retrospective study of 50 operated cases of cemented total hip replacement and a review of the literature enabled the authors to define the radiological features of the above-mentioned condition. These features include one or more of the following signs: calcar reabsorption, lacunar erosions, modified relatioships between the prosthesis components, sepsis and loosening, periarticular calcifications dislocation and fracture of prosthesis components. Careful evaluation of these radiological features is extremely important for both an early diagnosis of failed total hip replacement and the choice of an adequate surgical treatment

The use of hip arthroscopy continues to expand. Understanding potential pitfalls and complications associated with hip arthroscopy is paramount to optimizing clinical outcomes and minimizing unfavorable results. Potential pitfalls and complications are associated with preoperative factors such as patient selection, intraoperative factors such as iatrogenic damage, traction-related complications, inadequate correction of deformity, and nerve injury, or postoperative factors such as poor rehabilitation. This article outlines common factors that contribute to less-than-favorable outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

Hip fractures include fractures of the head, neck, intertrochanteric, and subtrochanteric regions. Head fractures commonly accompany dislocations. Neck fractures and intertrochanteric fractures occur with greatest frequency in elderly patients with a low bone mineral density and are produced by low-energy mechanisms. Subtrochanteric fractures occur in a predominantly strong cortical osseous region that is exposed to large compressive stresses. Implants used to address these fractures must accommodate significant loads while the fractures consolidate. Complications secondary to hip fractures produce significant morbidity and include infection, nonunion, malunion, decubitus ulcers, fat emboli, deep venous thrombosis, pulmonary embolus, pneumonia, myocardial infarction, stroke, and death.

Whereas hip arthroscopy plays a role in the investigation and treatment of the painful hip resurfacing arthroplasty, a diagnosis before arthroscopy is critical to improved outcome. The rate of conversion to total hip arthroplasty jumps from 7% to 37% when a pre-arthroscopy diagnosis is not known. Copyright © 2016 Arthroscopy Association of North America.

Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections (alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum -a major contributor to fracture healing- in the femoral neck. In extracapsular fractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

Hip hop dance has rapidly become a popular international art form. There is limited information on injury patterns in this population. The purpose of this study was to determine injury incidence and patterns among three groups of hip hop dancers. Three hundred and twelve intermediate, advanced, and expert hip hop dancers were recruited at battles, dance conferences, clubs, and on dance related web sites within the United States and internationally. A Web-based survey was conducted over a 6-month period. Inclusion criteria included intermediate and advanced level dancers over the age of 13. Dancers were divided into three main categories: Breakers, Popper/Lockers, and New Schoolers. Separate analysis of variances were used to compare injury pattern differences between groups. Two hundred and thirty-two dancers reported a total of 738 injuries. Five hundred and six of these (sustained by 205 dancers) were time-loss (TL) injuries. Annual injury incidence was 237% (162% involving TL). Lower extremity injuries were 52% and upper extremity injuries 32% of total injuries. Breakers had a higher injury incidence compared with Popper/Lockers, and New Schoolers. Hip hop dancers report injury rates that are higher than other dance forms but similar to gymnastics. These dancers should be educated concerning injury prevention, biomechanics, and use of protective equipment. © 2010 John Wiley & Sons A/S.

Adductor strain injuries are prevalent in ice hockey. It has long been speculated that adductor muscular strains may be caused by repeated eccentric contractions which decelerate the leg during a stride. The purpose of this study was to investigate the relationship of skating speed with muscle activity and lower limb kinematics, with a particular focus on the role of the hip adductors. Seven collegiate ice hockey players consented to participate. Surface electromyography (EMG) and kinematics of the lower extremities were measured at three skating velocities 3.33 m/s (slow), 5.00 m/s (medium) and 6.66 m/s (fast). The adductor magnus muscle exhibited disproportionately larger increases in peak muscle activation and significantly prolonged activation with increased speed. Stride rate and stride length also increased significantly with skating velocity, in contrast, hip, knee and ankle total ranges of motion did not. To accommodate for the increased stride rate with higher skating speeds, the rate of hip abduction increased significantly in concert with activations of adductor magnus indicating a substantial eccentric contraction. In conclusion, these findings highlight the functional importance of the adductor muscle group and hip abduction-adduction in skating performance as well as indirectly support the notion that groin strain injury potential increases with skating speed.

Full Text Available We compared kinetic characteristic of unipolar, bipolar and total hip endoprostheses, implanted after dislocated femoral neck fracture. Ninety patients were divided into three groups (30 patients in each group; a group with unipolar partial hip endoprosthesis (UPEP, a group with bipolar partial hip endoprosthesis (BPEP and a group with total hip endoprosthesis (TEP. The patients from different groups were paired by parameters which could influence the long term functional result: follow up period, comorbidities, functional capabilities before injury, etc. After the average follow up 3.8 +/- 1.9 years, a measuring of range of hip motions (ROM was conducted. The largest mean amplitudes in flexion (104 degrees, extension (13 degrees, abduction (35 degrees and external rotation (38 degrees was achieved BPEP, the largest adduction (14 degrees was achieved UPEP, and internal rotation (34 degrees TEP. Differences in ROMs are partially related to the clinical parameters such as: level of the hip pain, gait pattern, age and rehabilitation period (P < 0.05. Measuring of ROMs is the most reliable part of the clinical exam and it does not depend on subjectivity of patient, as opposed to other clinical parameters (level of pain, walking distance, aids usage, etc. The results obtained are favorable for the bipolar hip endoprosthesis, and they can be related to the biomechanical differences between the three types of hip endoprostheses. Kinetic advantages of the BPEP as compared to the UPEP, can be explained by the BPEP's structure: two-level mobility and a thinner neck which delays impingement in the late motion phase. In comparison to the TEP, clinical advantages of the BPEP can be attributed to less extensive surgery and scarring.

Magnetic resonance imaging (MRI) of the hips is being increasingly used to confirm hip reduction after surgery and spica cast placement for developmental dysplasia of the hip (DDH). To review a single institutional experience with post-spica MRI in children undergoing closed or open hip reduction and describe the utility of MRI in directing the need for re-intervention. Seventy-four patients (52 female, 22 male) who underwent post-spica hip MRI over a 6-year period were retrospectively reviewed. One hundred and seven hips were included. Data reviewed included age at intervention, gender, type of intervention performed, MRI findings, the need for re-intervention and the interval between interventions. Gender was compared between the closed and open reduction groups via the Fisher exact test. Age at the first procedure was compared via the Wilcoxon rank test. Rates of re-intervention after closed and open reduction were calculated and the reasons for re-intervention were reviewed. The mean age at the time of the first intervention was 16.4 months (range: 4 to 63 months). Mean age for the closed reduction group was 10.5 months (range: 4-24 months) and for the open reduction group was 23.7 months (range: 5-63 months), which was significant (P-value open reduction, MRI was useful in deciding re-intervention in only 1 (2%). This patient had prior multiple failed closed and open reductions at an outside institute. Post intervention hip spica MRI is useful in determining the need for re-intervention after closed hip reduction, but its role after open reduction is questionable.

Many risk factors have been identified for hip fracture, including female, advanced age, osteoporosis, previous fractures, low body weight or low body mass index, alcohol drinking, smoking, family history of fractures, use of glucocorticoid, factors related to falls, and bone strength. The factors related to falls are number of fall, frail, post stroke, paralysis, muscle weakness, anti-anxiety drugs, anti-depression drugs, and sedatives. Dementia and respiratory disease and others have been reported to be risk factors for secondary hip fracture.

Robotic lower limb exoskeletons hold significant potential for gait assistance and rehabilitation; however, we have a limited understanding of how people adapt to walking with robotic devices. The purpose of this study was to test the hypothesis that people reduce net muscle moments about their joints when robotic assistance is provided. This reduction in muscle moment results in a total joint moment (muscle plus exoskeleton) that is the same as the moment without the robotic assistance despite potential differences in joint angles. To test this hypothesis, eight healthy subjects trained with the robotic hip exoskeleton while walking on a force-measuring treadmill. The exoskeleton provided hip flexion assistance from approximately 33% to 53% of the gait cycle. We calculated the root mean squared difference (RMSD) between the average of data from the last 15 min of the powered condition and the unpowered condition. After completing three 30-min training sessions, the hip exoskeleton provided 27% of the total peak hip flexion moment during gait. Despite this substantial contribution from the exoskeleton, subjects walked with a total hip moment pattern (muscle plus exoskeleton) that was almost identical and more similar to the unpowered condition than the hip angle pattern (hip moment RMSD 0.027, angle RMSD 0.134, p<0.001). The angle and moment RMSD were not different for the knee and ankle joints. These findings support the concept that people adopt walking patterns with similar joint moment patterns despite differences in hip joint angles for a given walking speed.

Purpose With ethical requirements to the enrollment of lower risk subjects, osteoporosis trials are underpowered to detect reduction in hip fractures. Different skeletal sites have different levels of fracture risk and response to treatment. We sought to identify fracture sites which cluster with hip fracture at higher than expected frequency; if these sites respond to treatment similarly, then a composite fracture endpoint could provide a better estimate of hip fracture reduction. Methods Cohort study using Veterans Affairs and Medicare administrative data. Male Veterans (n=5,036,536) aged 50-99 years receiving VA primary care between1999-2009 were included. Fractures were ascertained using ICD9 and CPT codes and classified by skeletal site. Pearson correlation coefficients, logistic regression and kappa statistics, were used to describe the correlation between each fracture type and hip fracture within individuals, without regards to the timing of the events. Results 595,579 (11.8%) men suffered 1 or more fractures and 179,597 (3.6%) suffered 2 or more fractures during the time under study. Of those with one or more fractures, rib was the most common site (29%), followed by spine (22%), hip (21%) and femur (20%). The fracture types most highly correlated with hip fracture were pelvic/acetabular (Pearson correlation coefficient 0.25, p<0.0001), femur (0.15, p<0.0001), and shoulder (0.11, p<0.0001). Conclusions Pelvic, acetabular, femur, and shoulder fractures cluster with hip fractures within individuals at greater than expected frequency. If we observe similar treatment risk reductions within that cluster, subsequent trials could consider use of a composite endpoint to better estimate hip fracture risk. PMID:26151123

The calcium (Ca 2+ )-paradox injury of the heart, induced by restoration of extracellular Ca 2+ after its short-term depletion, is known to provoke cardiomyocyte contracture. However, undetermined is how the Ca 2+ -paradox provokes such a distinctive presentation of myocytes in the heart. To address this, we imaged sequential intracellular Ca 2+ dynamics and concomitant structures of the subepicardial ventricular myocytes in fluo3-loaded, Langendorff-perfused rat hearts produced by the Ca 2+ paradox. Under rapid-scanning confocal microscopy, repletion of Ca 2+ following its depletion produced high-frequency Ca 2+ waves in individual myocytes with asynchronous localized contractions, resulting in contracture within 10 min. Such alterations of myocytes were attenuated by 5-mM NiCl 2 , but not by verapamil, SEA0400, or combination of ryanodine and thapsigargin, indicating a contribution of non-specific transmembrane Ca 2+ influx in the injury. However, saponin-induced membrane permeabilization of Ca 2+ showed no apparent contracture despite the emergence of high-frequency Ca 2+ waves, indicating an essential role of myocyte-myocyte and myocyte-extracellular matrix (ECM) mechanical connections in the Ca 2+ paradox. In immunohistochemistry Ca 2+ depletion produced separation of the intercalated disc that expresses cadherin and dissipation of β-dystroglycan located along the sarcolemma. Taken together, along with the trans-sarcolemmal Ca 2+ influx, disruption of cell-cell and cell-ECM connections is essential for contracture in the Ca 2+ -paradox injury

BACKGROUND Pain associated with coxarthrosis, typically occurring in middle-aged and elderly patients, very commonly causes considerable limitation of motor fitness and dependence on pharmacotherapy. This article provides an assessment of a rehabilitation program with tailored water exercises in patients with osteoarthritis before and after total hip replacement. MATERIAL AND METHODS A total of 192 patients (the mean age 61.03±10.89) suffering from hip osteoarthritis (OA) were evaluated before and after total hip replacement (THR). The clinical study covered measurements of hip active ranges of motion (HAROM) and the forces generated by pelvis stabilizer muscles. Pain intensity was assessed according to analogue-visual scale of pain (VAS) and according to the Modified Laitinen Questionnaire. The patients were divided into 6 groups (4 treatment and 2 control). We compared 2 rehabilitation programs using kinesitherapy and low-frequency magnetic field. One of them also had specially designed exercises in the water. Statistical analysis was carried out at the significance level α=0.05. This was a cross-sectional study. RESULTS A positive effect of water exercises on a number of parameters was found in patients with OA both before and after total hip replacement surgery. We noted a significant reduction of pain (pwater exercises most significantly reduced pain in patients with OA before and after total hip replacement surgery. 2. Inclusion of water exercises in a rehabilitation program can reduce the use of medicines in patient with OA and after THR.

The purpose of this study was to report the clinical results of surgical dislocation of the hip in the treatment of pre-arthritic hip disease. Between 2005 and 2010, eighty-two patients (89 hips) underwent a surgical dislocation of the hip at a mean age of 30.5 years (range 14.8-51.7); 10 females and 72 males. At a mean follow-up of 7.1 years (range 5-9.6) clinical function improved significantly. 6 patients were converted to total hip arthroplasty and 3 patients underwent an arthroscopy and an additional three patients had >1mm of joint space narrowing at latest follow-up giving us a 9-year cumulative Kaplan-Meier survivorship of 86.4% (CI, 79% to 94%). Thirty-four patients underwent internal fixation removal at a mean of 12.0 months (range 0.3-40.8 months). Although effective in the treatment of early hip disease, the surgical dislocation approach carries a high re-operation rate for removal of internal fixation; consequently, less invasive approaches should be considered for less complex deformities.

Full Text Available The prevalence of class III obesity (BMI≥40 kg/m2 in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was successful as her BMI declined from 52.0 kg/m2 to 33.7 kg/m2. However, her hip circumference after weight loss remained persistently high. Therefore, at surgery the soft tissue tunnel geometry presented major challenges. Tunnel depth and immobility of the soft tissue interfered with retractor placement, tissue reflection, and surgical access to the acetabulum. Therefore a traditional cup placement could not be achieved. Instead, a hemiarthroplasty was performed. After surgery her pain and reliance on external support decreased. But her functional independence never improved. This case demonstrates that a lower BMI after bariatric surgery may improve the metabolic profile and decrease anesthesia risk, but the success of total hip arthroplasties remains problematic if fat mass in the operative field (i.e., high hip circumference remains high.

Vascular endothelial growth factor (VEGF) is a glycoprotein that plays an important role in neovascularization and increases vascular permeability. We reported that VEGF is involved in motion pain of patients with rotator cuff disease by causing synovial proliferation in the subacromial bursa (SAB). The present study investigates whether VEGF is also involved in the development of shoulder contracture in diabetics with rotator cuff disease. We examined 67 patients with rotator cuff disease, including 36 with complete cuff tears, 20 with incomplete tears, and 11 without apparent tears (subacromial bursitis). The patients were into groups according to the presence or absence of diabetes (14 type II diabetics and 53 non-diabetics). Specimens of the synovium of the SAB were obtained from all patients during surgery. Expression of the VEGF gene in the synovium of the subacromial bursa was evaluated by using the reverse transcriptase polymerase chain reaction. The VEGF protein was localized by immunohistochemistry, and the number of vessels was evaluated based on CD34 immunoreactivity. The results showed that VEGF mRNA was expressed in significantly more diabetics (100%, 14/14) than in non-diabetics (70%, 37/53) (P=0.0159, Fisher's test). Investigation of VEGF isoform expression revealed VEGF121 in all 14 diabetics and in 37 of the 53 non-diabetics, VEGF165 in 12 of the 14 diabetics and in 21 of the 53 non-diabetics, and VEGF189 in 1 of the 14 diabetics and in 2 of the 53 non-diabetics. No VEGF206 was expressed in either group. VEGF protein was localized in both vascular endothelial cells and synovial lining cells. The mean number of VEGF-positive vessels and the vessel area were also significantly greater in the diabetics (pshoulder joint contracture were more common in the diabetics (P=0.0329 and P=0.073, respectively; Fisher's test). The mean preoperative range of shoulder motion significantly differed in terms of elevation between two groups: 103.8 degrees in

Purpose: In early stage Dupuytren's contracture radiotherapy was applied to prevent disease progression. Long-term results and late toxicity of this treatment were evaluated in a retrospective analysis. Patients and Methods: Between 1982 and 1994, 99 patients (176 hands) received orthovoltage radiotherapy, which consisted of two courses with 5 x 3 Gy (total dose: 30 Gy, daily fractionated; 120 kV, 4 mm Al), separated by a 6 to 8-week pause. The Dupuytren's contracture was staged according to the classification of Tubiana et al. The long-term outcome was analyzed at last follow-up between July and November 1999. The median follow-up was 10 years (range 7-18 years). Late toxicity was assessed using the LENT-SOMA criteria. Results: In Stage N 84% and Stage N/I 67% of cases remained stable. 65% of the cases in Stage I and 83% in Stage II showed progressive nodules and cords. In case of progression we saw no complications after a second radiotherapy or salvage operation. Conclusion: Radiotherapy effectively prevents disease progression for early stage Dupuytren's contracture (Stage N, N/I). Moreover, in case of disease progression despite radiotherapy salvage surgery is still feasible. (orig.)

ABSTRACT With increased knowledge and understanding of hip pathology, hip arthroscopy is rapidly becoming a popular treatment option for young patients with hip pain. Despite improved clinical and radiographic outcomes with arthroscopic treatment, some patients may have ongoing pain and less than satisfactory outcomes. While the reasons leading to failed hip arthroscopy are multifactorial, patient selection, surgical technique and rehabilitation all play a role. Patients with failed hip arthroscopy should undergo a thorough history and physical examination, as well as indicated imaging. A treatment plan should then be developed based on pertinent findings from the workup and in conjunction with the patient. Depending on the etiology of failed hip arthroscopy, management may be nonsurgical or surgical, which may include revision arthroscopic or open surgery, periacetabular osteotomy or joint arthroplasty. Revision surgery may be appropriate in settings including, but not limited to, incompletely treated femoroacetabular impingement, postoperative adhesions, heterotopic ossification, instability, hip dysplasia or advanced degeneration.

Painful hip following hip dislocation or acetabular fracture can be an important signal for early degeneration and progression to osteoarthritis due to intraarticular pathology. However, there is limited literature discussing the use of arthroscopy for the treatment of painful hip. The purpose of this retrospective study was to analyze the effectiveness and benefit of arthroscopic treatment for patients with a painful hip after major trauma. From July 2003 to February 2013, we reviewed 13 patients who underwent arthroscopic treatment after acetabular fracture or hip dislocation and were followed up for a minimum of 2 postoperative years. The degree of osteoarthritis based on the Tonnis classification pre- and postoperatively at final follow-up was determined. Clinical outcomes were evaluated using visual analogue scale for pain (VAS) and modified Harris hip score (MHHS), and range of motion (ROM) of the hip pre- and postoperatively at final follow-up. There were nine male and four female patients with a mean age at surgery of 28 years (range, 20 to 50 years). The mean follow-up period of the patients was 59.8 months (range, 24 to 115 months), and the mean interval between initial trauma and arthroscopic treatment was 40.8 months (range, 1 to 144 months). At the final follow-up, VAS and MHHS improved significantly from 6.3 and 53.4 to 3.0 and 88.3, respectively (p = 0.002 and p hip flexion, abduction, adduction, external rotation, and internal rotation as minor improvements from 113.1°, 38.5°, 28.5°, 36.5°, and 22.7° to 118.5°, 39.0°, 29.2°, 38.9°, and 26.5° were observed, respectively (p = 0.070, p = 0.414, p = 0.317, p = 0.084, and p = 0.136, respectively). None of the patients exhibited progression of osteoarthritis of the hip at the final follow-up. Arthroscopic treatment after acetabular fracture or hip dislocation is effective and delays the progression of traumatic osteoarthritis.
