Global perspectives on risk factors for major joint burn contractures: A literature review.

Contractures are a frequent consequence of burn injuries, yet our knowledge of associated risk factors is limited. This paper provides an extensive review of relevant literature from both High-Income Countries (HICs) and Low-Middle Income Countries (LMICs). Ninety-four papers (up to June 2019) and eight subsequent publications (up to March 2022) were included, 76% of which were from HICs. The majority of publications were either descriptive studies (4 from HICs, 9 from LMICs) or papers citing putative risk factors (37 from HICs, 10 from LMICs). Seventeen publications (all from HICs) reported on the effects of individual non-surgical therapeutic interventions, often with conflicting results. Two published systematic reviews emphasised the poor quality of evidence available. Only fifteen studies (3 from LMICs) examined potential contracture risk factors with statistical comparisons of outcomes; significant findings from these included demographic, burn, comorbidities, and treatment risk factors. LMIC papers included socioeconomic and healthcare system factors as potential risks for contracture; these were rarely considered in HIC publications. Methodological issues identified from this review of literature included differences in contracture definitions, populations studied, standards of care, joints included and the timing and nature of contracture assessments.This review is the first to collate existing knowledge on risk factors for burn contractures from both HIC and LMIC settings, revealing a surprising lack of robust evidence for many accepted risk factors. In LMICs, where burns are particularly common, universal health provision is lacking and specialist burn care is both scarce and difficult to access; consequently, socioeconomic factors may have more immediate impact on contracture outcomes than specific burn treatments or therapies. Much more work is indicated to fully understand the relative impacts of risk factors in different settings so that context-appropriate contracture prevention strategies can be developed.

Prospective Study of Clinical Outcomes From a Breast Implant Assessment Service.

BACKGROUND: Breast augmentation remains the commonest cosmetic surgical procedure worldwide, in spite of recent regulatory action. OBJECTIVES: The aim of this study was to evaluate women with breast implants attending a breast implant assessment clinic and to capture clinical and implant data in women presenting to the service. METHODS: Patients were enrolled prospectively between January 2018 and December 2021. Clinical, implant, and practitioner data were recorded. Patients reported satisfaction on size, shape, and overall outcome as well as the presence or pain. Radiological evaluation, where indicated, was performed and data were included on these findings. RESULTS: A total of 603 patients were assessed. Their mean age was 42.7 years and mean age at implantation was 29.1 years. The most common complications were capsular contracture followed by pain, waterfall deformity, and double bubble, with rupture/contracture rates increasing after the 10-year mark. The risk of double bubble was significantly lower if patients were operated on by certified practitioners (odds ratio = 0.49, P = 0.011). There was almost universally poor awareness of the risks of breast implants in patients presenting for evaluation. CONCLUSIONS: This study has shown benefit in a breast implant assessment clinic to gather information on adverse events and patient-reported outcomes following breast implant surgery. Having appropriately trained and certified practitioners perform cosmetic augmentation significantly lowers the risk of implant malposition and deformity. Any adverse event occurring within 5 years of initial surgery should be flagged as a mandatory reportable clinical indicator and trigger further investigation.

A randomized controlled trial: Comparison of one-per-mil tumescent technique and tourniquet in surgery for burn hand contracture in creating clear operative field and assessment of functional outcome.

BACKGROUND: This study aims to compare the use of one-per-mil tumescent solution (a mixture of epinephrine and 0.2% lidocaine in a ratio of 1:1,000,000 in normal saline solution) and tourniquet to create clear operative fields and to evaluate the functional outcomes after post burn hand contracture surgery. METHODS: The subjects of this randomized controlled trial were divided into one-permil tumescent technique and tourniquet group for a similar surgical procedure. Three independent assessors evaluated the clarity of the operative fields through recorded videos for the first 15 min and the first 10-minute of each hour of the surgery. Functional outcome was evaluated at least three months postoperatively using total active and passive motion (TAM and TPM) of each digit. Malondialdehyde (MDA) and tumor necrosis factor alpha (TNF-α) were tested during baseline (5 min before the procedures), ischemia phase, and reperfusion phase (a phase when the blood flow returned to the tissue). RESULTS: 35 subjects were included in this study: 17 in the tumescent group and 18 in the tourniquet group. We found a significant difference in the clarity of operative field between tumescent and tourniquet groups, 5 vs 35 bloodless operative fields, respectively (p < 0.05). TAM and TPM of each digit before surgery and 3 months postoperatively showed no significant difference between both groups (p > 0.05). Furthermore, we found no difference in MDA and TNF-α levels between both groups at their respective phases. CONCLUSIONS: The use of one-per-mil tumescent technique does not replace tourniquet use to create bloodless operative fields in burned hand contracture surgery. However, the postoperative functional results were similar in both groups showing that tumescent technique can be used as an alternative to tourniquet without compromising outcomes. The MDA and TNF-α examinations do not provide conclusive outcomes regarding ischemia and reperfusion injury.

Access to Burn Care in Low- and Middle-Income Countries: An Assessment of Timeliness, Surgical Capacity, and Affordability in a Regional Referral Hospital in Tanzania.

This study investigates patients' access to surgical care for burns in a low- and middle-income setting by studying timeliness, surgical capacity, and affordability. A survey was conducted in a regional referral hospital in Manyara, Tanzania. In total, 67 patients were included. To obtain information on burn victims in need of surgical care, irrespective of time lapsed from the burn injury, both patients with burn wounds and patients with contractures were included. Information provided by patients and/or caregivers was supplemented with data from patient files and interviews with hospital administration and physicians. In the burn wound group, 50% reached a facility within 24 hours after the injury. Referrals from other health facilities to the regional referral hospital were made within 3 weeks for 74% in this group. Of contracture patients, 74% had sought healthcare after the acute burn injury. Of the same group, only 4% had been treated with skin grafts beforehand, and 70% never received surgical care or a referral. Together, both groups indicated that lack of trust, surgical capacity, and referral timeliness were important factors negatively affecting patient access to surgical care. Accounting for hospital fees indicated patients routinely exceeded the catastrophic expenditure threshold. It was determined that healthcare for burn victims is without financial risk protection. We recommend strengthening burn care and reconstructive surgical programs in similar settings, using a more comprehensive health systems approach to identify and address both medical and socioeconomic factors that determine patient mortality and disability.

Cutaneous laser surgery for secondary burn reconstruction: Cost benefit analysis.

Thermal disease presents a major burden to individual patient morbidity, healthcare cost as well as to over all economy. Burns also also represent a significant per-patient utlilisation of finite healthcare resources. Secondary complications in these patients, such as multiple drug resistant organisms, may have a devastating effect. Laser surgery has recently come of age as an optimal tool in the secondary reconstruction of burn injury, that is able to simultaneously address significant sheet scar tightness, hypertrophic, atrophic, and keloid complications, pruritus, microstomia, ectropion, skin graft honeycombing, and improve range of movement whilst reducing the risk of infection to <1%. Yet, cutaneous laser surgery is often underutilised due to the perceived concerns about the sustainability of a new service with relatively high startup cost. We present a dual methodology to explore this concern: an evidence-based background review of the last 5 years of current best evidence, and a 22-year cost-analysis comparison at an established, high volume UK Centre of reconstructive surgery. We report that fiscal viability for laser surgery services for secondary burn reconstruction is supported by: level 2 (one systematic review) level 4 evidence (2 studies) and level 5 evidence (expert reports). Evidence over 22 years from an established super-regional NHS laser centre shows that introduction of this service led to sustained and substantial cost saving, producing excellent surgical results at a fraction of the cost of traditional surgery. Analysis of the potential dollar-effect of these advantages to the general population supports state investment in expertise and capital equipment as a medium to long-term cost saving strategy, which may also aid re-integrating patients into the workforce making a meaningful contribution to the economy.

Upper Extremity Burns in the Developing World: A Neglected Epidemic.

Burns are devastating injuries that cause significant morbidity, emotional distress, and decreased quality of life. Advances in care have improved survival and functional outcomes; however, burns remain a major public health problem in developing countries. More than 95% of burns occur in low- and middle-income countries, where access to basic health care is limited. The upper extremity is involved in the majority of severe burn injuries. The purpose of this article is to review upper extremity burn epidemiology, risk factors, prevention strategies, and treatment options in resource-limited settings.

Quantitative Assessment of Muscle Strength Following "Slow" Surgical Lengthening of the Medial Hamstring Muscles in Children With Cerebral Palsy.

BACKGROUND: Classic teaching for surgical lengthening of muscle contractures in children with cerebral palsy (CP) has emphasized complete correction of the deformity acutely, with immobilization of the targeted muscles in the fully corrected position. Clinical experience has led to the impression that the muscles are invariably weakened by this approach. We have developed an alternative technique for correction of contractures called slow surgical lengthening (SSL). The goal of the study was to determine the physical examination, kinematic, and muscle strength outcomes following SSL of the medial hamstring muscles in children with CP. METHODS: The study group included 41 children with CP who underwent SSL of the medial hamstring muscles as part of a comprehensive single-event multilevel surgery, who had preoperative and 1-year postoperative evaluations in our Motion Analysis Center, which included quantitative assessment of isometric and isokinetic muscle strength. RESULTS: All subjects were Gross Motor Function Classification System I and II. Mean age at the time of surgery was 10.8 years. The mean popliteal angle improved by 16.2 degrees (P<0.001) following SSL of the medial hamstrings. Sagittal plane kinematics following SSL of the medial hamstrings showed improvement of knee extension at initial contact of 10.2 degrees (P<0.001), decrease of peak knee flexion in mid-swing of 3.6 degrees (P=0.014), improved minimum knee flexion in stance of 4.9 degrees (P=0.002), and no significant change in mean anterior pelvic tilt (P=0.123). Mean peak isometric knee flexion torque remained unchanged from preoperative to postoperative studies (P=0.154), whereas mean peak isokinetic knee flexion torque significantly increased by 0.076 Nm/kg (P=0.014) following medial hamstring SSL. DISCUSSION: SSL was developed based upon clinical experience and improved understanding of the pathophysiology of skeletal muscle in children with CP. The SSL technique allows the tendinous tissue to separate spontaneously at the time of recession, but does not force further acute lengthening by intraoperative manipulation, thereby minimizing the damage to the underlying muscle. It is broadly believed that muscle weakness is inevitable following surgical lengthening. The current study shows that the SSL technique does not cause weakness. LEVEL OF EVIDENCE: Level IV-therapeutic.

Prospective outcome assessment of arthroscopic arthrolysis for traumatic and degenerative elbow contracture.

BACKGROUND: The purpose of this study was to evaluate the efficacy of arthroscopic elbow release for both traumatic and degenerative contractures from intraoperative recording through the recovery time until final follow-up. METHODS: The study is based on 54 consecutive patients with extrinsic elbow contracture (traumatic in 31 and degenerative in 23) treated with arthroscopic arthrolysis by a single surgeon in 2011-2015. Range of motion (ROM) and the Mayo Elbow Performance Score (MEPS) were recorded preoperatively; intraoperatively; following release; and in the 1st, 3rd, 8th, 12th, and 26th weeks and at 2 years postoperatively. RESULTS: Significant improvements were noted in extension, flexion, and range of motion, measured both intraoperatively and at all follow-up visits. The greatest improvement in the range of motion was achieved at the time of surgery (from 89° ± 28° to 131° ± 14°, P < .001); it then decreased at 1 week to 103° ± 22° (P < .001) and slowly recovered to reach 124° ± 22° after 2 years. This was better than the preoperative value (P < .001) but worse than the intraoperative value (P = .002). A similar pattern was observed in both traumatic and degenerative contractures. The MEPS improved from 73 ± 12 preoperatively to 93 ± 14 at the final evaluation (P < .001). The ROM and MEPS results at every follow-up were comparable for both traumatic and degenerative contractures. ROM improved regardless of the severity of contracture. CONCLUSIONS: Arthroscopic elbow arthrolysis was similarly efficient in ROM restoration in both traumatic and degenerative contractures and regardless of the severity of contracture. After early deterioration, the achieved gain slowly recovers over a period of 6 months but may not recover to the ranges achieved during arthroscopy.

DupuytrEn Treatment EffeCtiveness Trial (DETECT): a protocol for prospective, randomised, controlled, outcome assessor-blinded, three-armed parallel 1:1:1, multicentre trial comparing the effectiveness and cost of collagenase clostridium histolyticum, percutaneous needle fasciotomy and limited fasciectomy as short-term and long-term treatment strategies in Dupuytren's contracture.

INTRODUCTION: Dupuytren's contracture (DC) is a chronic fibroproliferative disorder of the palmar fascia which leads to flexion contracture in one or more fingers. There is no definitive cure for DC, and treatment aims at relieving symptoms by releasing the contracture using percutaneous or operative techniques. METHODS AND ANALYSIS: We planned a prospective, randomised, controlled, outcome assessor-blinded, three-armed parallel 1:1:1, multicentre trial comparing the effectiveness and cost of (1) collagenase clostridium histolyticum injection followed by limited fasciectomy in non-responsive cases, (2) percutaneous needle fasciotomy followed by limited fasciectomy in non-responsive cases and (3) primary limited fasciectomy during short-term and long-term follow-up for Tubiana I-III stages DC. We will recruit participants from seven national centres in Finland. Primary outcome is the rate of success in the treatment arm at 5 years after recruitment. Success is a composite outcome comprising (1) at least 50% contracture release from the date of recruitment and (2) participants in a patient-accepted symptom state (PASS). Secondary outcomes are (1) angle of contracture, (2) quick disabilities of the arm, a shoulder and hand outcome measure (QuickDASH), (3) perceived hand function, (4) EQ-5D-3L, (5) rate of major adverse events, (6) patient's trust of the treatment, (7) global rating, (8) rate of PASS, (9) rate of minimal clinically important improvement, (10) expenses, (11) progression of disease, (12) progression-free survival, (13) favoured treatment modality, (14) patients achieving full contracture release and >50% improvement and (15) patient satisfaction with the treatment effect. Predictive factors for achieving the PASS will also be analysed. ETHICS AND DISSEMINATION: The protocol was approved by the Tampere University Hospital Institutional Review Board and Finnish Medicine Agency. The study will be performed according to the principles of good clinical practice. The results of the trial will be disseminated as published articles in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03192020; Pre-results.

The Stanford-ReSurge Burn Scar Contracture Scale for Neck: Development and Initial Validation for Burn Scar Contracture.

BACKGROUND: Burn contractures can cause significant disability, particularly in patients in resource-limited settings. However, a gap exists in our ability to measure outcomes in patients with burn contractures of the neck. The objective of this study was to develop and validate the Stanford-ReSurge Burn Scar Contracture Scale-Neck to longitudinally assess functional status and measure functional improvement following contracture release of the neck. METHODS: A literature review was performed to identify scales used in neck assessment and burn assessment. Items were then removed from the pool based on redundancy, feasibility, cultural appropriateness, and applicability to patients in international resource-limited environments. Remaining items were administered to patients with burn contracture of the neck. RESULTS: The initial literature review found 33 scales that were combined to create an initial pool of 714 items, which was first reduced to 40 items. Feedback from field testing then yielded a 20-item outcome tool to assess appearance, activities of daily living, somatosensation, satisfaction, and range of motion, with a floor of 20 and a ceiling score of 100 points. Preliminary testing with 10 patients showed an average preoperative score of 58 points and an average 1-month postoperative score of 42 points. CONCLUSIONS: The authors have created an outcome tool for measuring functional status following burn contracture release of the neck, which can easily be implemented in resource-limited settings where the burden of burn injuries and morbidities is disproportionately high. Ongoing work includes a multicountry study to evaluate validity and reliability.

Functional and subjective assessment of burn contracture release in a mission setting.

OBJECTIVE: Burns and subsequent contractures are common in developing nations. Contracture release is performed to treat such patients with functional limitations. The aim of this study is to evaluate post-operative functional and psychosocial outcomes following contracture release in a mission setting. METHODS: During a surgical mission in Mumbai, India, 39 patients burn contractures underwent surgical release. A total of 31 patients (64% female, mean age 27 years) chose to participate in the study. Patients were scored preoperatively and postoperatively using a SF-36 validated survey and AMA impairment guideline assessment. RESULTS: Thirty-one patients completed questionnaires pre-operative and 6-weeks post operatively. Twenty-four patients completed a survey 3-months post operatively (77.4%). Among those enrolled, 67% were women with the majority sustaining <20% total body surface area burns (70.7%) but had multiple contractures (80.6%). SF-36 physical component score increased from a mean score of 49.8 preoperatively to 55.6 by 3 months following contracture release (P<0.001). The SF-36 mental component score similarly increased from 38.8 to 51.1 by 3 months (P<0.001). AMA Whole Person Impairment (WPI) scores improved from 40.3% impairment pre-operative to 26.6% at 6-weeks post-operative (P<0.001). CONCLUSIONS: Patients SF-36 and WPI scores improved following burn contracture release, confirming both functional and psychologic improvement following surgery. During the acute post-operative period, this study suggests that contracture release in a mission setting is of benefit to patients.

Early experience with fat grafting as an adjunct for secondary burn reconstruction in the hand: Technique, hand function assessment and aesthetic outcomes.

INTRODUCTION: Fat transfer is increasingly used as part of our reconstructive armamentarium to address the challenges encountered in secondary burn reconstruction. The aim of this study was to review our experience with autologous fat transfer in relation to hand function, scarring and cosmesis, in patients undergoing secondary reconstruction after burns. METHOD: Retrospective analysis of burn patients (2010-2013) who underwent autologous fat transfer to improve scarring, contour deformity and/or scar contracture was performed. Hand function was assessed using grip strength measurement, Total Active Movement (TAM), the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire and Michigan Hand Outcome Questionnaire (MHQ). Patients' satisfaction was assessed using the Patient Observer Scar Assessment Scale (POSAS). RESULTS: Thirteen patients were included in this analysis. The average time from burns and from fat transfer were 2.3 years (10 months-3.9 years) and 9.1 months (3 months-1.3 years), respectively. There was a statistically significant improvement in TAM measurement. The total score, activity of daily living score and satisfaction score of the MHQ also statistically increased following fat transfer. The changes in function score, work score and pain score of the MHQ were not significant. Grip strength measurement and DASH score did not show improvement. For scar assessment, total score and overall score of POSAS improved significantly. Similarly, scores for scar colour, scar thickness, scar stiffness and scar regularity increased significantly. DISCUSSION: Autologous fat transfer directly replaces volume loss in the subcutaneous layer, physically releases tethered skin from underlying tissues and exerts downstream regenerative effects. Skin quality improvements combined with replacement of the subcutaneous adipose volume in the hand reduces overall scar tightness and tissue tethering and has the potential to enhance hand therapy. In our series, modest improvement in range of movement, scar quality and hand outcome scores were demonstrated following a single session of fat transfer.

Assessment of quality of life (QoL) of burn patients in India using BSHS-RBA scale.

INTRODUCTION: The Burn Specific Health Scale-Brief (BSHS-B) is a popular instrument to measure quality of life (QoL) in burn patients. The current study aims at identifying the prognostic variables for our burn population using the BSHS-RBA (revised, brief and adapted) scale. MATERIALS AND METHODS: The study was conducted on 60 post-burn patients using the BSHS-RBA scale. The questionnaire was administered by an interview as majority of patients were illiterate. The socio-demographic and clinical variables were analyzed against domain scores and total scores of the scale, using Mann-Whitney test and Kruskal Wallis test. RESULTS: The median age of the sample was 28 years, of which 60% were females. Their median TBSA burn was 30%. The median time since burn at the time of interview was 10 months. Higher scores were noted in the domains of simple abilities and mobility, hand function and interpersonal relationship, while poorer scores were recorded in domains of skin sensitivity and body image. DISCUSSION: The mean score in our study was 2.36, which is quite less as compared to reports from high income countries (range: 2.58-3.36). This study provides an insight on an aspect of burn care outcome, which can be reasonably expected in low income countries with the available standard of care. Being a female, presence of hand and face burn, requirement of corrective surgeries and inability to resume work were factors associated with poor QoL. CONCLUSION: Strategies to improve QoL of burn patients should target psychological aspects, work rehabilitation (early release of contractures) and skin hypersensitivity (including itching) to derive maximum benefit.

Assessment of Acute Burn Management in 32 Low- and Middle-Income Countries.

BACKGROUND: The purpose of this study is to ascertain whether acute burn management (ABM) is available at health facilities in low- and middle-income countries (LMICs). METHOD: The study used the World Health Organization situational analysis tool (SAT) which is designed to assess emergency and essential surgical care and includes data points relevant to the acute management of burns. The SAT was available for 1413 health facilities in 59 countries. RESULTS: A majority (1036, 77.5 %) of the health facilities are able to perform ABM. The main reasons for the referral of ABM are lack of skills (53.4 %) and non-functioning equipment (52.2 %). Considering health centres and district/rural/community hospitals that referred due to lack of supplies/drugs and/or non-functioning equipment, almost half of the facilities were not able to provide continuous and consistent access to the equipment required either for resuscitation or to perform burn wound debridement. Out of the facilities that performed ABM, 379 (36.6 %) are capable of carrying out skin grafts and contracture release, which is indicative of their ability to manage full thickness burns. However the magnitude of full thickness burns managed was limited in half of these facilities, as they did not have access to a blood bank. CONCLUSION: The initial management of acute burns is generally available in LMICs, however it is constrained by the inability to perform resuscitation (19 %) and/or burn wound debridement (10 %). For more severe burns, an inability to perform skin grafting or contracture release limits definitive management of full thickness burns, whilst lack of availability to blood further compromises the treatment of major burns.

Assessment of clinical outcome of percutaneous needle quadriceps tenotomy in the treatment of congenital knee dislocation.

PURPOSE: Treatment of congenital knee dislocation (CDK) depends on the severity and flexibility of the deformity. Various modalities of treatment ranging from serial cast, open quadricepsplasty and minimally invasive quadricepsplasty have been described. We describe percutaneous needle quadriceps tenotomy for treatment of flexible CDK and present our result of retrospective case series. METHODS: This was a retrospective study of 12 patients (20 knees) with flexible CDK. Eight patients with bilateral and four with unilateral deformities. The mean age of intervention was 14.5 days (range, 4-55 days). None of the patients were syndromic. All procedures were done within eight weeks of age. The outcome was measured using knee evaluation score and complications in view of extensor lag, instability and knee flexion deformity. Ultrasound was performed to check for integrity of quadriceps mechanism. RESULTS: The mean pre-operative hyperextension was 50° (range, 30-70°). All patients were able to achieve >90° flexion intra-operatively. The mean knee flexion at walking age was 135° (range, 130-140°). Knee evaluation score showed good results in nine patients and fair result in three patients. There was no extensor lag, knee flexion deformity or infection. One patient of anterior instability had ACL aplasia which was documented on MRI. Ultrasound performed at walking age showed normal functioning of quadriceps mechanism. CONCLUSIONS: Percutaneous needle tenotomy of quadriceps is a effective, simple and safe procedure for flexible, non syndromic CDK presenting early. It avoids complications associated with the open surgical procedure and causes less extensor scarring. However its effectiveness in stiff/hyperlax variants associated with syndromes is yet to be determined.

Reconstructive surgery after burns: a 10-year follow-up study.

BACKGROUND: There is minimal insight into the prevalence of reconstructive surgery after burns. The objective of this study was to analyse the prevalence, predictors, indications, techniques and medical costs of reconstructive surgery after burns. METHODS: A retrospective cohort study was conducted in the three Dutch burn centres. Patients with acute burns, admitted from January 1998 until December 2001, were included. Data on patient and injury characteristics and reconstructive surgery details were collected in a 10-year follow-up period. RESULTS: In 13.0% (n=229/1768) of the patients with burns, reconstructive surgery was performed during the 10-year follow-up period. Mean number of reconstructive procedure per patient were 3.6 (range 1-25). Frequently reconstructed locations were hands and head/neck. The most important indication was scar contracture and the most applied technique was release plus random flaps/skin grafting. Mean medical costs of reconstructive surgery per patient over 10-years were €8342. CONCLUSIONS: With this study we elucidated the reconstructive needs of patients after burns. The data presented can be used as reference in future studies that aim to improve scar quality of burns and decrease the need for reconstructive surgery.

Improvement in quality of life after arthroscopic capsular release for contracture of the shoulder.

There is little published information on the health impact of frozen shoulder. The purpose of this study was to assess the functional and health-related quality of life outcomes following arthroscopic capsular release (ACR) for contracture of the shoulder. Between January 2010 and January 2012 all patients who had failed non-operative treatment including anti-inflammatory medication, physiotherapy and glenohumeral joint injections for contracture of the shoulder and who subsequently underwent an ACR were enrolled in the study. A total of 100 patients were eligible; 68 underwent ACR alone and 32 had ACR with a subacromial decompression (ASD). ACR resulted in a highly significant improvement in the range of movement and functional outcome, as measured by the Oxford shoulder score and EuroQol EQ-5D index. The mean cost of a quality-adjusted life year (QALY) for an ACR and ACR with an ASD was £2563 and £3189, respectively. ACR is thus a cost-effective procedure that can restore relatively normal function and health-related quality of life in most patients with a contracture of the shoulder within six months after surgery; and the beneficial effects are not related to the duration of the presenting symptoms.

In muscle lengthening surgery multiple aponeurotomy does not improve intended acute effects and may counter-indicate: an assessment by finite element modelling.

The goal was to assess the effects of multiple aponeurotomy on mechanics of muscle with extramuscular myofascial connections. Using finite element modelling, effects of combinations of the intervention carried out at a proximal (P), an intermediate (I) and a distal (D) location were studied: (1) Case P, (2) Case P-I, (3) Case P-D and (4) Case P-I-D. Compared to Case P, the effects of multiple interventions on muscle geometry and sarcomere lengths were sizable for the distal population of muscle fibres: e.g. at high muscle length (1) summed gap lengths between the cut ends of aponeurosis increased by 16, 25 and 27% for Cases P-I, P-D and P-I-D, respectively, (2) characteristic substantial sarcomere shortening became more pronounced (mean shortening was 26, 29, 30 and 31% for Cases P, P-I, P-D and P-I-D, respectively) and (3) fibre stresses decreased (mean stress equalled 0.49, 0.39, 0.38 and 0.33 for Cases P, P-I, P-D and P-I-D, respectively). In contrast, no appreciable effects were shown for the proximal population. The overall change in sarcomere length heterogeneity was limited. Consequently, the effects of multiple aponeurotomy on muscle length-force characteristics were marginal: (1) a limited reduction in active muscle force (maximal 'muscle weakening effect' remained between 5 and 11%) and (2) an even less pronounced change in slack to optimum length range of force exertion (maximal 'muscle lengthening effect' distally was 0.2% for Case P-I-D) were shown. The intended effects of the intervention were dominated by the one intervention carried out closer to the tendon suggesting that aponeurotomies done additionally to that may counter-indicated.

Biomechanical assessment of brachioradialis pronatorplasty.

OBJECTIVES: Transfer of the brachioradialis muscle, proposed by Özkan et al. can be applied to cases, in which, the biceps rerouting technique is not appropriate for the correction of forearm supination contracture and restoration of active pronation. We have aimed to assess the biomechanical effects of the brachioradialis transfer. METHODS: Pronation strength was acquired in nine fresh-frozen cadaver forearms by applying rerouting of the brachioradialis muscle through interosseous membrane (Group 1) or transferring the same muscle to the distal insertion of extensor carpi ulnaris (ECU) (Group 2). Then, a force of 5 to 35 N was applied to the muscle and the range of forearm rotation and rotation strength were measured. The normalities of the data were analyzed by Shapiro-Wilk test. Comparisons between the groups were made with independent-sample t-test and comparison of the data, obtained from the same group, was carried out with paired-sample t-test and Bonferroni correction. RESULTS: A maximum of 74° (with a mean of 61°) gain of pronation with rerouting and a maximum of 72° (with a mean of 65°) gain with ECU transfer of brachioradialis muscle were observed. A significant regression was also found in the first group. Regression constant was - 9.59 (p = 0.001, 95%: -13.20; -6.00) for the applied force of 2.06 N (p = 0.001, 95%: 1.90; 2.22). Furthermore, a significant regression was found in the second group. Regression constant was - 9.73 (p = 0.001, 95%: -13.13; -6.34) for the applied force of 1.91 N (p = 0.001, 95%: 1.76; 2.06). CONCLUSION: The brachioradialis muscle works as a pronator in full forearm supination. However, when the forearm comes close to the neutral rotation, due to the lateral location of the proximal insertion, the brachioradialis muscle loses this pronator effect. The additional release or lengthening of contracted soft tissues increases the range of pronation.

The clenched fist syndrome: a presentation of eight cases and an analysis of the medicolegal aspects in Denmark.

Clenched fist is a rare disorder of the hand associated with fixed contractures of fingers. The condition is often preceded by minor trauma or surgery, but these do not explain the severity of the contractures. Extension of the fingers is painful and hygienic problems can be considerable. Psychiatric disease is frequent in clenched fist patients. The patients may express a strong wish for amputations. In a review of eight patients with clenched fist who had claimed economic compensation from the Danish Patient Insurance Association, four patients had amputations. Three of them subsequently developed new contractures.
