Aims. Complete ruptures of the ulnar collateral ligament (UCL) of the thumb are a common injury, yet little is known about their current management in the UK. The objective of this study was to assess the way complete UCL ruptures are managed in the UK. Methods. We carried out a multicentre, survey-based cross-sectional study in 37 UK centres over a 16-month period from June 2022 to September 2023. The survey results were analyzed descriptively. Results. A total of 37 centres participated, of which nine were tertiary referral hand centres and 28 were district general hospitals. There was a total of 112 respondents (69 surgeons and 43 hand therapists). The strongest influence on the decision to offer surgery was the lack of a firm ‘endpoint’ to stressing the metacarpophalangeal joint (MCPJ) in either full extension or with the MCPJ in 30° of flexion. There was variability in whether additional imaging was used in managing acute UCL injuries, with 46% routinely using additional imaging while 54% did not. The use of a bone anchor was by far the most common surgical option for reconstructing an acute ligament avulsion (97%, n = 67) with a transosseous suture used by 3% (n = 2). The most common duration of immobilization for those managed conservatively was six weeks (58%, n = 65) and four weeks (30%, n = 34). Most surgeons (87%, n = 60) and hand therapists (95%, n = 41) would consider randomizing patients with complete UCL ruptures in a future clinical trial. Conclusion. The management of complete UCL ruptures in the UK is highly variable in certain areas, and there is a willingness for clinical trials on this subject.

Aims. The conventionally described mechanism of distal biceps tendon rupture (DBTR) is of a ‘considerable extension force suddenly applied to a resisting, actively flexed forearm’. This has been commonly paraphrased as an ‘eccentric contracture to a flexed elbow’. Both definitions have been frequently used in the literature with little objective analysis or citation. The aim of the present study was to use video footage of real time distal biceps ruptures to revisit and objectively define the mechanism of injury. Methods. An online search identified 61 videos reporting a DBTR. Videos were independently reviewed by three surgeons to assess forearm rotation, elbow flexion, shoulder position, and type of muscle contraction being exerted at the time of rupture. Prospective data on mechanism of injury and arm position was also collected concurrently for 22 consecutive patients diagnosed with an acute DBTR in order to corroborate the video analysis. Results. Four videos were excluded, leaving 57 for final analysis. Mechanisms of injury included deadlift, bicep curls, calisthenics, arm wrestling, heavy lifting, and boxing. In all, 98% of ruptures occurred with the arm in supination and 89% occurred at 0° to 10° of elbow flexion. Regarding muscle activity, 88% occurred during isometric contraction, 7% during eccentric contraction, and 5% during concentric contraction. Interobserver correlation scores were calculated as 0.66 to 0.89 using the free-marginal Fleiss Kappa tool. The prospectively collected patient data was consistent with the video analysis, with 82% of injuries occurring in supination and 95% in relative elbow extension. Conclusion. Contrary to the classically described injury mechanism, in this study the usual arm position during DBTR was forearm supination and elbow extension, and the muscle contraction was typically isometric. This was demonstrated for both video analysis and ‘real’ patients across a range of activities leading to rupture. Cite this article: Bone Jt Open 2022;3(10):826–831

Aims. The aim of this systematic review and meta-analysis was to gather epidemiological information on selected musculoskeletal injuries and to provide pooled injury-specific incidence rates. Methods. PubMed (National Library of Medicine) and Scopus (Elsevier) databases were searched. Articles were eligible for inclusion if they reported incidence rate (or count with population at risk), contained data on adult population, and were written in English language. The number of cases and population at risk were collected, and the pooled incidence rates (per 100,000 person-years) with 95% confidence intervals (CIs) were calculated by using either a fixed or random effects model. Results. The screening of titles yielded 206 articles eligible for inclusion in the study. Of these, 173 (84%) articles provided sufficient information to be included in the pooled incidence rates. Incidences of fractures were investigated in 154 studies, and the most common fractures in the whole adult population based on the pooled incidence rates were distal radius fractures (212.0, 95% CI 178.1 to 252.4 per 100,000 person-years), finger fractures (117.1, 95% CI 105.3 to 130.2 per 100,000 person-years), and hip fractures (112.9, 95% CI 82.2 to 154.9 per 100,000 person-years). The most common sprains and dislocations were ankle sprains (429.4, 95% CI 243.0 to 759.0 per 100,000 person-years) and first-time patellar dislocations (32.8, 95% CI 21.6 to 49.7 per 100,000 person-years). The most common injuries were anterior cruciate ligament (17.5, 95% CI 6.0 to 50.2 per 100,000 person-years) and Achilles (13.7, 95% CI 9.6 to 19.5 per 100,000 person-years) ruptures. Conclusion. The presented pooled incidence estimates serve as important references in assessing the global economic and social burden of musculoskeletal injuries.

Determine the infection risk of nonoperative versus operative repair of extraperitoneal bladder ruptures in patients with pelvic ring injuries. Pelvic ring injuries with extraperitoneal bladder ruptures were identified from a prospective trauma registry at two level 1 trauma centers from 2014 to 2020. Patients, injuries, treatments, and complications were reviewed. Using Fisher's exact test with significance at P value < 0.05, associations between injury treatment and outcomes were determined. Of the 1127 patients with pelvic ring injuries, 68 (6%) had a concomitant extraperitoneal bladder rupture. All patients received IV antibiotics for an average of 2.5 days. A suprapubic catheter was placed in 4 patients. Bladder repairs were performed in 55 (81%) patients, 28 of those simultaneous with ORIF anterior pelvic ring. The other 27 bladder repair patients underwent initial ex-lap with bladder repair and on average had pelvic fixation 2.2 days later. Nonoperative management of bladder rupture with prolonged Foley catheterization was used in 13 patients. Improved fracture reduction was noted in the ORIF cohort compared to the closed reduction external fixation cohort (P = 0.04). There were 5 (7%) deep infections. Deep infection was associated with nonoperative management of bladder rupture (P = 0.003) and use of a suprapubic catheter (P = 0.02). Not repairing the bladder increased odds of infection 17-fold compared to repair (OR 16.9, 95% CI 1.75 – 164, P = 0.01). Operative repair of extraperitoneal bladder ruptures substantially decreases risk of infection in patients with pelvic ring injuries. ORIF of anterior pelvic ring does not increase risk of infection and results in better reductions compared to closed reduction. Suprapubic catheters should be avoided if possible due to increased infection risk later. Treatment algorithms for pelvic ring injuries with extraperitoneal bladder ruptures should recommend early bladder repair and emphasize anterior pelvic ORIF

Abstract. Objectives. Achilles tendon ruptures are common in the UK, with data demonstrating a significant rise in incidence over the past years. Chronic Achilles ruptures have been less well defined in literature, and repair techniques vary significantly. A surge in publications reporting various management options for chronic Achilles ruptures has necessitated a review that systematically maps and summarises current evidence regarding treatments and identifies areas for future research. This scoping review aims to improve knowledge of various treatment strategies and their associated outcomes, thereby aiding clinicians in optimising treatment protocols. Methods. The Arksey and O'Malley, Levac and Peters frameworks were used. A computer-based search in PubMed, Embase, Emcare, Cinahl, ISI Web of Science and Scopus was performed for articles reporting the treatment of chronic Achilles ruptures. Two reviewers independently performed title/abstract and full text screening according to a pre-defined selection criteria. Results. A total of 747 articles were identified, of which 73 were finally included. Various management strategies were described with flexor hallucis longus tendon transfer being the most common. The American Orthopaedic Foot and Ankle Society (AOFAS) score was the most commonly reported outcome, but 16 other measures were described within the literatures. All studies comparing pre- and post-operative outcomes reported a significant improvement. 50 studies reported complications, with an overall pooled complication rate of 168/1065 (15.8%). Conclusions. Beneficial results were reported following various techniques, but comparison between these was challenging due to the low-level study designs used and confounding factors including treatment delay and tendon gap size. Further research exploring the efficacy of different techniques is required to facilitate the development of evidenced-based treatment protocols. Such a work would allow for clinicians to better understand the suitability of specific techniques, thereby selecting the optimal management strategy for each individual patient

There is currently no commercially available and clinically successful treatment for scapholunate interosseous ligament rupture, the latter leading to the development of hand-wrist osteoarthritis. We have created a novel biodegradable implant which fixed the dissociated scaphoid and lunate bones and encourages regeneration of the ruptured native ligament. To determine if scaphoid and lunate kinematics in cadaveric specimens were maintained during robotic manipulation, when comparing the native wrist with intact ligament and when the implant was installed. Ten cadaveric experiments were performed with identical conditions, except for implant geometry that was personalised to the anatomy of each cadaveric specimen. Each cadaveric arm was mounted upright in a six degrees of freedom robot using k-wires drilled through the radius, ulna, and metacarpals. Infrared markers were attached to scaphoid, lunate, radius, and 3rd metacarpal. Cadaveric specimens were robotically manipulated through flexion-extension and ulnar-radial deviation by ±40° and ±30°, respectively. The cadaveric scaphoid and lunate kinematics were examined with 1) intact native ligament, 2) severed ligament, 3) and installed implant. Digital wrist models were generated from computed tomography scans and included implant geometry, orientation, and location. Motion data were filtered and aligned relative to neutral wrist in the digital models of each specimen using anatomical landmarks. Implant insertion points in the scaphoid and lunate over time were then calculated using digital models, marker data, and inverse kinematics. Root mean squared distance was compared between severed and implant configurations, relative to intact. Preliminary data from five cadaveric specimens indicate that the implant reduced distance between scaphoid and lunate compared to severed configuration for all but three trials. Preliminary results indicate our novel implant reduced scapho-lunate gap caused by ligament transection. Future analysis will reveal if the implant can achieve wrist kinematics similar to the native intact wrist

Introduction. Chronic ruptures of the quadriceps tendon after total knee arthroplasty (TKA) are rare but are a devastating complication. The objective of this study was to validate the use of fresh frozen total fresh quadriceps tendon allografts for quadriceps tendon reconstruction. The hypothesis of this work was that the graft was functional in more than 67% of cases, a higher percentage than the results of conventional treatments. Material – methods. We designed a continuous monocentric retrospective study of all patients operated on between 2009 and 2017 for a chronic rupture of the quadriceps tendon after TKA by quadriceps allograft reconstruction. The usual demographic and perioperative data and the rehabilitation protocols followed were collected. Initial and final radiographs were analyzed to measure patellar height variation. The main criterion was the possibility of achieving an active extension of the knee with a quadriceps contraction force greater than or equal to 3/5 or the possibility of lifting the heel off the ground in a sitting position. Results. 29 patients with 33 allografts were included; 3 iterative allografts were performed on ruptures of the initial transplant and 1 patient was grafted on both sides in one step. There were 21 women and 8 men with a mean age of 73 years, and a mean body mass index of 33 kg/m. 2. Ruptures occurred in 22 cases after chronic periprosthetic infection. Walking was allowed immediately in 29 cases, but free mobilization was delayed in 29 cases. Complications affected 22 cases, but the majority of complications were not related to allograft use (including infectious failures and periprosthetic fractures). After a mean follow-up of 52 months, 28 allografts were still in place, and 22 allografts were considered functional. The active quadriceps extension force was rated on average at 3.5/5. The average pre/post-operative patellar height differential was +2 mm. Discussion. This continuous series of 33 allografts is in line with recent publications on the subject. It confirms their negative impact on the functional outcome of the TKA. The complication rate is high but the specific complication rate is not prohibitive. Two thirds of transplants are functional in the long term. Early rehabilitation procedures can be used in these difficult patients with encouraging results. The management of chronic ruptures of the quadriceps tendon after TKA by quadriceps allograft must be part of the current therapeutic options

Aims. This prospective cohort study aimed to determine if the size of the tendon gap following acute tendo Achillis rupture influences the functional outcome following non-operative treatment. Patients and methods. All patients presenting with acute unilateral tendo Achillis rupture were considered for the study. Dynamic ultrasound examination was performed to confirm the diagnosis and measure the gap between ruptured tendon ends. Outcome was assessed using dynamometric testing of plantarflexion and the Achilles tendon rupture score (ATRS) six months after the completion of a rehabilitation programme. Results. 38 patients (mean age 52 years, range 29–78 years) completed the study. Patients with a gap ≥10mm with the ankle in the neutral position had significantly greater peak torque deficit than those with gaps < 10mm (mean 23.3% vs 14.3%, P=0.023). However, there was no overall correlation between gap size and torque deficit (τ=0.103), suggesting a non-linear relationship. There was also weak correlation between ATRS and peak torque deficit (τ=−0.305), with no difference in ATRS between the two groups (mean score 87.2 vs 87.4, P=0.467). Conclusion. This is the first study to identify tendon gap size as a predictor of functional outcome in acute tendo Achillis rupture, although the precise relationship between gap size and plantarflexion strength remains unclear. Large, multi-centre studies will be needed to clarify this relationship and identify population subgroups in whom deficits in peak torque are reflected in patient-reported outcome measures

The recent introduction of intra-articular local anaesthetic techniques following total joint arthroplasty have demonstrated improvements in post-operative pain control, early joint mobilisation and may contribute to early discharge. Following intra-operative infiltration, the CALEDonian Technique requires ropivicaine to be administered postoperatively via an epidural catheter and filter, 20 to 40 ml over 60 seconds, on three occasions. Epidural filter catheters are used to prevent bacterial contamination during injection and have demonstrated 100% efficacy when intact. However, on internal departmental audit we have become aware of a filter membrane rupture rate approximating 10%. We therefore investigated the variables of syringe size and rate of administration in the occurrence of filter ruptures. Using a standard primed epidural catheter set (Perifix B Braun), pressure measurements were taken pre- and post-filter. Recordings using the filter with attached catheter tubing were undertaken using 5 ml, 10 ml and 20 ml syringes (n=10) during infusion of a standard 5 ml volume. Controlled (over 1 min and following departmental protocol) and forced (over less than 15 seconds) infusions were undertaken manually and the experiment also undertaken using an automated syringe driver with 40 ml infused at a rate of 400 ml/hr. Each experiment was repeated ten times. Infusion pressures were measured and filters examined for evidence of rupture. Using departmental protocol, controlled infusions independent of syringe size generated consistently low pressures, averaging 115 kPa, with no filter ruptures. Forced administration, independent of syringe size, generated pressures averaging 625.1 kPa. This is above the filter threshold and resulted in almost universal filter rupture. An automated device infusing at a rate of 400 ml/hr again generated low pressures and no filter ruptures. Our study demonstrates low infusion pressures and no filter ruptures, independent of syringe size, when departmental protocol is adhered to suggesting that a human element may be in-part responsible for filter rupture. Although the technique currently used is safe, our audit has raised awareness of a potential difficulty and has lead to re-education of staff involved in this process. Consideration is being given to the possibility of automating infusions in the future and a process of re-audit of filter rupture will be undertaken

The recent advance of drug therapy for RA tends to replace preventive surgery, for example synovectomy. A rupture of a dorsal extensor tendon of the hand is an absolute indication for surgery, however. Such tendon ruptures are usually treated by tendon reconstruction and synovectomy of wrist joint. At our department, reconstructive surgery was administered with synovectomy for extensor tendon ruptures of the hand in 97 hands for 86 patients until June 2005. Recently, however, we occasionally encounter ruptures of extensor tendons not associated with severe synovitis. To treat such tendon ruptures, we usually administer tendon transfers in combination with tenosynovectomy through a small skin incision. Because this surgical procedure has achieved excellent results, we report our experience. This study included 15 patients who received tenosynovectomy in combination with tendon transfers in 14 hands since February 2001. This surgical procedure is indicated for tendon ruptures associated with mild synovitis (swelling) without instability on the ulnar distal end. As a rule, a 2–3 cm transverse skin incision was made on the dorsum of the hand under maxillary nerve block. After exposure of the distal ruptured end of the tendon, tenosynovectomy was administered through the incision. Then, the distal end was transferred to the adjacent normal tendon and fixed to it with sutures. Postoperatively, the repair was immobilized with bandage. The patient was allowed actively to extend and bend the hand on the next day. As a rule, this operation is administered on an outpatient basis. The postoperative course was uneventful, without rupture of the repair. The preoperative ranges of motion of the MP and PIP joints were retained postoperatively without difficulty in ADL

Introduction. Growing evidence in the literature suggests better clinical and functional outcomes and lower re-rupture rates with repair compared to non-operative treatment of ruptured Achilles tendon. There are however, concerns of wound infection, nerve injury and scar tenderness with the standard open and percutaneous techniques of repair. We aim to evaluate clinical and functional outcomes and complications in patients treated with minimally invasive Achillon device. Materials and Methods. Prospectively collected clinical data was reviewed of all consecutive patients who underwent repair of the ruptured Achilles tendon using the Achillon device. Patients were contacted using a postal questionnaire for assessment of their functional status using the validated Achilles Tendon Total Rupture Score (ATRS) and compared with their uninjured side. The outcomes were compared to the published results. Results. We present patient demographics; and clinical and functional outcomes of 140 consecutive patients who underwent repair of ruptured Achilles tendon using the minimally invasive technique between June 2007 to August 2010. Our complication rate was of two-three percent each of proximal DVT, scar sensitivity, superficial wound infection and no re-rupture after a minimum of 6 months. There was no case of nerve injury leading to permanent neurological deficit. Discussion. This study demonstrates good clinical and functional outcomes from using the Achillon device in repair of ruptured Achilles tendon with a low complication rate comparable to other published series. We recommend Achillon device as a safe minimally invasive technique for repair of the ruptured Achilles tendon

Pectoralis major tendon rupture is a relatively rare injury, resulting from violent, eccentric contraction of the muscle. Over fifty percent of these injuries occur in athletes classically in weight-lifters during bench press. In this study, thirteen cases of distal rupture of the pectoralis major muscle in athletes are presented. All patients underwent surgical repair. Physical findings and surgical technique are described. Magnetic resonance imaging was used in the diagnosis of all patients and intra-operative findings correlated with the reported scans in eleven patients with minor differences in two patients. During follow up examination, six patients had excellent results, six had good results and one had a fair result. Eleven patients could return to sports activity at their preoperative level. Among our patients we emphasize that of an orthopaedic resident who suffered a rupture of his pectoralis major tendon as an unusual complication of closed manipulation of an anterior shoulder dislocation. According to the literature and our experience, we suggest that only surgical repair of the pectoralis major rupture will result in complete recovery and restoration of the full strength of the muscle which is essential for the active athlete

Introduction and Aims: Pectoralis major tendon rupture is a relatively rare injury, resulting from violent, eccentric contraction of the muscle. Over 50percent of these injuries occur in athletes, classically in weight-lifters during bench press. Method: In this study, 13 cases of rupture of the pectoralis major muscle in athletes are presented. All patients underwent surgical repair. Physical findings and surgical technique are described. Magnetic resonance imaging was used in the diagnosis of all patients. Intra-operative findings correlated with the reported scans in 11 patients with minor differences in two patients. Results: During follow-up examination, six patients had excellent results, six had good results and one had a fair result. Eleven patients could return to sports activity at their pre-operative level. Among our patients we emphasise that of an orthopaedic resident who suffered a rupture of his pectoralis major tendon as an unusual complication of closed manipulation of an anterior shoulder dislocation. Conclusion: According to the literature and our experience, we suggest that only surgical repair of the pectoralis major rupture will result in complete recovery and restoration of the full strength of the muscle, which is essential for the active athlete

Introduction: Ruptures of the glutaeus minimus tendon at the greater trochanter may be a reason for persisting pain after total hip replacement. The aim of this study was to investigate the frequency of the rupture of the glutaeus minimus tendon at the greater trochanter in patients with osteoarthritis of the hip. Patients and Methods: From May until August 2004, total hip joints were implanted in 67 conscutive patients with osteoarthritis of the hip joint. 54 of the operations were done with a standard Watson-Jones approach. 13 patients were operated with a minimal invasive approach without visualisation of the gluteaus minimus tendon. For the minimal invasive approach only patients with a normal appearance ot the X-ray of the greater trochanter were selected. The integrity of the insertion of the glutaeus minimus tendon was recorded during the operation with the Watson-Jones approach und compared to the X-ray findings. Results: There were 8 complete and 13 partial ruptures of the glutaeus minimus tendon in 54 patients with the Watson-Jones approach. The mean age of the patients with rupture was 75.0 years compared to 67.2 years of the patients without rupture.The Y-rays ot the hip in two planes showed osteophytes at the greater trochanter in 18 (86 %) with a ruptur and in no patient without a ruptur. The frequnece of a complete or partial rupture of the glutaeus minimus tendon was at least 31% in the 67 patients of this study. Conclusion: Ruptures of the glutaeus minimus tendon are common in patients with osteoarthritis o thi hip but it is unknown whether it is necessary to reinsert the tendon during the implantation of an artificial hip joint

Introduction. It is an example of tendon to bone healing of rotator cuff tears. Low Level Laser Therapy (LLLT) is used in pain literature, pain palliation, tendinopathies, osteoarthritis treatment, implant osteointegration in jaw surgery, wound healing, fracture healing, tendon healing, nerve healing. But; there is not a study on tendon-bone healing. It is aimed to investigate the effects of tendon to bone healing with the rotator cuff experimental tear model. Material and Methods. 60 Wistor Albino Rat right shoulders were used in our project in four groups. Effectiveness of the study in each study group to increase and use the minimum number of animals that would be significant it was planned to use 15 (6 histology + 9 biomechanical) subjects. In our study, there are 4 groups in total. 1. Group 4. Week sacrified control group 2. Group 4. Week sacrificed LLLT group 3. Group 8. Week sacrified control group 4. Group is postoperative LLLT group. The 4 round SSP tendons have been cut with a full course. A total of eight sessions of biostimulation were performed with 24 j energy per session. Biomechanical tensile test and histopathological examination were performed on rats sacrificed at 4 and 8 weeks. In histological examination, cellularity at the repair site with hemotoxylin-eosin staining, extracellular matrix localization with Masson trichrome staining and fibrosis, TRAP (Tartrate Resistance Acid Phosphatase) and osteoclast activity, collagen fibril organization with picrochucine were evaluated. In immunohistological examination, proliferation activity was evaluated by CD-31 (Abcam, Cambridge, MA, USA) through vascular endothelial cells, Ki-67 (Tucson, AZ) and tendon proliferation index. Failure load for comparison of biomechanical stability between groups drawing will be done. Biomechanical pulling applications Linear pulling force over tendon It will be realized by applying. Last failure load (Newton), elongation (mm) and hardness values was recorded. Results. Two rats died in the postoperative first group and one rat died in the other groups. Six animals from each group were examined histopathologically. While the mean of stifness was higher in the patient who underwent LLLT at the 4th week biomechanically compared to the control group, there was no difference in the 8th week between the control group LLLT biomechanically. Histologically, the group with LLLT at 4 weeks showed increased fibroblastic activity and osteoclastic activity, but at 8 weeks there was no significant difference. Discussion. There are studies on the benefits of biostimulation with LLLT in fracture healing, implant integration, wound healing, tendon healing. Biostimulation experiments with LLLT for tendon healing were evaluated in rotator cuff healing as they were not available in literature. Especially early contributions were thought to be beneficial for postoperative rupture

Summary. Nearly one-third of patients in this series with an ACL rupture requiring reconstruction had evidence of MPFL injury. This should be considered when patients are seen, and when MRI scans are reviewed/reported. Introduction. The Medial Patello-Femoral Ligament (MPFL) is the largest component of the medial parapatellar ligamentous complex. The senior surgeon felt that there was an anecdotally high rate of MPFL injury amongst his patients undergoing Anterior Cruciate Ligament (ACL) repair, but no discussion of this in the present literature. Method. A literature search was performed; although there were both scanty radiographic and anatomical studies of the MPFL, we found no literature looking at ACL and MPFL concurrent injury rates. The Magnetic Resonance Imaging (MRI) scans of fifty consecutive ACL reconstruction patients were retrospectively reviewed. Two independent radiologists were asked to review the scans looking specifically for evidence of MPFL rupture or Injury. The degree of injury was rated as rupture or by degree of sprain as applicable. One patient was excluded due to motion artefact limiting certainty. Results. Of the remaining forty-nine patients, 35 (71%) were intact, but fourteen (29%) showed evidence of injury. Five (10%) had a low-grade sprain, six (12%) had high-grade sprain, and three (6%) had complete rupture. The radiologists also noted that there was some variation in scanning protocols, and those with fat suppressed scans had better diagnostic value; this offered an opportunity to change the scanning practice. Conclusion. Nearly one-third of patients in this series with an ACL rupture requiring reconstruction had evidence of MPFL injury. This should be considered when patients are seen, and when MRI scans are reviewed/reported. Further, we would suggest that fat suppression sequences are included as standard to improve imaging quality

Isolated rupture of short head of biceps is a rare injury. There have been no published reports of rupture at the musculotendinous junction. We report two cases of complete rupture of the musculotendinous junction of the short head of biceps in young males both occurring during water skiing. Two males sustained water skiing injuries where the handle was forced against the flexor region of the arm. Whilst trying to adduct and flex the extended arm, they both sustained complete musculotendinous ruptured of their short head of biceps. Both underwent pre-operative magnetic resonance imaging and one underwent isokinetic strength testing of elbow flexion and supination. Surgical repair was performed using absorbable sutures. One patient had the short head muscle belly flipped distally to lie in a subcutaneous plane in front of the elbow. Post-operative management included cast immobilisation for three weeks then gentle range of motion exercises. Both patients recovered their full range of motion in the arm. There were no complications. Post-operative strength testing was performed and will be presented. This is a unique series of complete musculotendinous rupture of the short head of biceps. The mechanism of injury was resisted adduction and flexion against the towrope handle with the arm in extension. These ruptures occurred in high impact high velocity accidents. Surgical repair lead to an excellent outcome

Introduction: The anterior cruciate ligament (ACL) can be anatomically divided into two bundles: the anteromedial (AM) and the posterolateral (PL). These two bundles have unique contributions to load transfer across the knee joint. Material and Methods: We retrospectively reviewed the clinical results of a consecutive series of 25 patients who underwent partial ACL reconstruction. In 22 cases AM bundle reconstruction was performed, and in 3 patients isolated PL bundle reconstruction was performed. The 25 patients included 7 women and 18 men with an average age of 29.2 years at the time of surgery. Preoperative evaluation was conducted using manual Lachman test, pivot-shift tests, KT-1000, magnetic resonance imaging and passive stress radiographs of both knees. In all cases preoperative clinical evaluation was graded C as per the IKDC scoring system. The preoperative side-to-side anterior laxity measured by means of the KT-1000 was 5.8 mm in case of AM bundle rupture and 4.3 mm in case of PL bundle rupture. All the patients underwent single-bundle reconstruction of the ACL under arthroscopic assistance (one single incision technique). In case of AM bundle repair, the type of graft used was all autologous and included bone-patellar tendon-bone in 14 cases, 4-strand hamstring tendons in 5 cases and 2-strand hamstring tendons in 3 cases. In case of PL bundle repair, 2-strand hamstring tendons transplant was used in the 3 cases. Results: In all cases, postoperative clinical evaluation was graded A as per the IKDC knee examination scoring system. No abnormal sagittal laxity was found with the Lachman manual test. Postoperative IKDC knee subjective evaluation score averaged 81.3 % [58–95] at an average of 9 months follow-up. Postoperative side-to-side anterior laxity measured with KT-1000 averaged 0.46 mm in case of AM bundle rupture and 0.5 mm in case of PL bundle rupture. Postoperatively, all the patients had full extension of the knee. The flexion was the same as contra lateral knee in 92 % of the cases. We had no postoperative complication. Discussion: Diagnosis of partial ACL rupture is often difficult. If the AM bundle is torn, the Lachman manual test is soft and the pivot-shift test is more often equal or glide. If the Lachman manual test is intermediary between firm and soft and the pivot-shift test is clunk, PL rupture has probably occurred. The size of the graft was smaller than in one bundle procedures and was matched with the size of the bundle reconstucted. Peroperative technical difficulties were to preserve the healthy bundle and to drill the femoral tunnel in case of posterolateral bundle reconstruction. Conclusion: This study showed consistent postoperative results. If partial rupture of the ACL can be diagnosed, isolated AM or PL bundle reconstruction should be considered

Background. Conservative treatment of acute AT ruptures with functional rehabilitation has demonstrated superior results with equal reported re-rupture rates but without the added complications of surgical treatment. There is no consensus on the duration and method of treatment using functional rehabilitation regimes. The purpose of this paper is to define our treatment regime, the Leicester Achilles Management Protocol (LAMP), supported with patient reported outcomes and objective measures of assessment. Methods. All patients with an acute achilles tendon rupture were treated with the same non-operative LAMP functional rehabilitation regime in a VACOped boot for 8 weeks. 12 months post rupture ATRS scores and objective measures of calf muscle girth and heel raise height were obtained and analysed. Venous thromboembolic rates and rates of re-rupture were recorded. Results. 442 patients were treated with this regime between February 2011 and December 2015. The incidence of a thromboembolic event was 5.9% and a re-rupture rate of 2%. The ATRS score at 12 months was available in 200 patients. Objective measures were available in 50 patients. The average age was 50 years (range 21–82). The average ATRS score was 75.3 (SD 22, 95% CI 72.2 – 78.4) at an average follow up of 25 months post injury. Men had better ATRS than women (P< 0.05). The calf muscle girth and heel raise height were significantly different from the uninjured side. However, these did not correlate with the ATRS (P>0.05). Conclusions. The LAMP is a simple effective regime which is very easy to adopt and involves a VACOped boot for 8 weeks. Compared to other studies, the overall time in the boot is less with similar patient reported outcomes. Implications. Simple non-operative functional rehabilitation regime that can be applied to ALL patients with acute achilles tendon ruptures

A key factor delaying rehabilitation after a tendo Achillis (TA) rupture is gait abnormality. We quantified changes in planter pressures after a rupture of the TA in four groups of patients:. 15 controls subjects, mean 40 years, with no history of lower limb abnormality. 14 patients, mean 48 years, treated in a non-weight-bearing plaster cast. 12 patients, mean age 45 years, treated with immediate weight-bearing in a ‘rigid’ orthosis. 14 patients, mean age 51 years, treated with immediate weight-bearing in a ‘flexible’ orthosis. Mean and maximum peak planter pressures within the forefoot and heel were measured using in-shoe pressure pads two weeks after removal of the cast/orthosis; five gait cycles were recorded. The terminal stance and pre-swing phases were also measured as a proportion of the total stance phase of the gait cycle. One-way ANOVA was used to compare the difference in means between the groups. The normal control group had less than 2% difference between the limbs on all of the measured parameters. The patients in the plaster cast and ‘rigid’ orthotic groups had significant deficits (p = 0.04 and < 0.001 compared to control) in mean peak forefoot pressures, implying weakness in the triceps surae. However, the patients in the flexible orthosis group had only an 11% deficit (p = 0.25 compared to control). All of the patients treated for a TA rupture had increased heel pressures but only the ‘rigid’ orthotic group had cadence abnormalities (p = < 0.001). This may be the result of abnormal motor patterns secondary to mobilising in the rigid orthosis. This study highlights the gait abnormalities associated with triceps surae weakness following rupture of the TA. Accelerated rehabilitation using weight-bearing orthotics may alleviate some of these problems, but new designs for flexible orthotics may be required for maximum benefit
