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.

A case of complete rupture of the axillary artery in a man aged eighty-seven is described. The injury occurred in connection with an antero-inferior dislocation of the shoulder. It is not known whether the rupture was caused by the dislocation itself or by the reduction. A successful suture of the artery was performed. A review of the literature is given, and earlier attempts to suture the artery in cases of this type are noted. The indications for this operation are discussed

Aims. The purpose of this study was to evaluate the relationships between the degree of injury to the medial and lateral collateral ligaments (MCL and LCL) and associated fractures in patients with a posterolateral dislocation of the elbow, using CT and MRI. Methods. We retrospectively reviewed 64 patients who presented between March 2009 and March 2018 with a posterolateral dislocation of the elbow and who underwent CT and MRI. CT revealed fractures of the radial head, coronoid process, and medial and lateral humeral epicondyles. MRI was used to identify contusion of the bone and collateral ligament injuries by tear, partial or complete tear. Results. A total of 54 patients had a fracture; some had more than one. Radial head fractures were found in 25 patients and coronoid fractures in 42. Lateral and medial humeral epicondylar fractures were found in eight and six patients, respectively. Contusion of the capitellum was found in 43 patients and rupture of the LCL was seen in all patients (partial in eight and complete in 56), there was complete rupture of the MCL in 37 patients, partial rupture in 19 and eight had no evidence of rupture. The LCL tear did not significantly correlate with the presence of fracture, but the MCL rupture was complete in patients with a radial head fracture (p = 0.047) and there was significantly increased association in those without a coronoid fracture (p = 0.015). Conclusion. In posterolateral dislocation of the elbow, LCL ruptures are mostly complete, while the MCL exhibits various degrees of injury, which are significantly associated with the associated fractures.

Abstract. Objectives. This study aims to evaluate the functional outcomes of early weight-bearing in a functional orthosis for conservatively managed, complete AT ruptures. Also we tried to evaluate the patient reported outcome with this form of treatment. Design. In this prospective study, we have analysed data from 41 patients with ultrasound diagnosed compete AT ruptures, with a gap of less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protocol, followed by rehabilitation with a trained physiotherapist. Methods. Patients were followed up with foot and ankle trained physiotherapist for at least 1 year post-injury. At final follow up, the followings were measured: calf girth, single-leg heel raise height and repetitions. Furthermore, ATRS score and a patient feedback were taken on this final visit. Result. The mean ATRS score was 82.1, with a re-rupture rate of only 2% as compared to 5% in normal orthosis. The average calf bulk difference was 1.6 cm, the average heel raise height difference was 1.8cm and a heel raise repetition difference of 6. There was a statistically significant correlation between ATRS score and calf muscle girth (p=0.02). However, there was no significant correlation between ATRS and heel raise height or heel raise repetitions. Conclusion. Early weight-bearing in a functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. A multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome

Purpose: The accurate preoperative evaluation of impingement syndrome and rotator cuff lesions, as well as the confirmation of the clinical and operative findings. Material-Method: 281 patients with clinical findings of impingement syndrome and/or lesions of the rotator cuff were evaluated with MRI. Results: The following MRI diagnoses were made: tendons’ lesions 306 (degeneration 138, complete rupture 116, partial rupture 52), impingement 196. The following RC lesions were in association with impingement syndrome: degenerative changes 106, complete rupture 101, incomplete rupture 48. The above mentioned tendon lesions were in many patients in all forms of degeneration (mixed). The dimention of all complete ruptures were measured on the MRI (116). In 93 patients of them operation followed. The MRI findings were confirmed in all patients except three (the operative findings showed 8,10,15 mms larger tears in comparison with the MRI measurements, 2, 4.5 and 5 months post-MRI examination respectively). Comparing the clinical and MRI findings we found agreement in 83.54%, unclear clinical diagnosis in 5.06%, partial agreement in 8.86% and disagreement in 2.53%. Conclusions: MRI is an excellent method in evaluating the rotator cuff lesions and those of the impingement syndrome as well as the extend and degree of muscle atrophy. More important though is the accurate evaluation of the extend and quality of RC lesions, which are closely related to the result of surgical intervention

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

Hamstring muscle strain is a common sports related injury. It has been reported in a variety of sports, following acceleration or deceleration while running or jumping. Injury may vary from simple muscle strains to partial or complete rupture of the hamstring origin. Avulsion fracture of the ischial tuberosity has also been described. Simple hamstring muscle strains are treated conservatively. Surgical exploration and repair is currently advocated for partial or complete rupture of the hamstring origin. A few case series exists in literature suggesting the benefits of early intervention. We report a series of 8 athletes who presented between 2002 and 2006 with complete tear of their hamstring origin. Avulsion of the ischial tuberosity was excluded in these cases. After confirming the diagnosis, early surgical exploration and repair or reattachment was performed. The patients were braced for 8 weeks. This was followed by specialist physiotherapy and a supervised rehabilitation programme over 6 months. All patients were followed up to monitor return to normal activities and sports. The sciatic nerve was scarred to the avulsed tendon in three cases. Neurolysis led to a rapid relief of symptoms. Cases where the hamstring origin had retracted more than 3 cm required a figure 7 incision. There were no major complications including nerve palsies. An excellent functional outcome was noted by 12 months in all 8 patients. 7 of them returned to their previous level within 6-9 months of injury. One person despite a very good recovery, opted out of sports. No other complications were seen as a result of the surgical procedure. In conclusion, a tear of the origin of hamstring muscles is a significant injury. Early surgical repair and physiotherapy is associated with a good outcome and enables an early return to high level sports

Introduction. Autologous chondrocyte implantation (ACI) is contra-indicated in a joint rendered unstable by a ruptured anterior cruciate ligament (ACL). We present our experience of ACI repair with ACL reconstruction. Methods. Patients underwent arthroscopic examination and cartilage harvesting of the knee. A second operation was undertaken approximately six weeks later to repair the ruptured ACL with hamstring graft or Bone patella-Bone (BPB) and to implant the chondrocytes via formal arthrotomy. Three groups were assessed: Group 1: Simultaneous ACL Reconstruction and ACI; Group 2: Previous ACL Reconstruction with subsequent ACI repair; Group 3: Previously proven partial or complete ACL rupture, deemed stable and not treated with reconstruction with ACI procedure subsequently. Patients then underwent a graduated rehabilitation program and were reviewed using three functional measurements: Bentley functional scale, the modified Cincinnati rating system, and pain measured on a visual analogue scale. All patients also underwent formal clinical examination at review. Results. Those who underwent simultaneous ACL Reconstruction and ACI had a 47% improvement in Bentley functional scale, 36% improvement in visual analogue score and 38% improvement in the modified Cincinnati rating system. This is in contrast to only a 15% improvement in the modified Cincinnati rating system, 30% improvement in Bentley functional scale, and 32% improvement in visual analogue score in patients who had ACI repair after previous ACL reconstruction. 68% of patients who had the procedures simultaneously rated their outcome as excellent/good and 27% felt it was a failure. In contrast 38% of patients rated their outcome as a failure if they had ACI repair without reconstruction of ACL rupture. Conclusion. Symptomatic cartilage defects and ACL deficiency may co-exist in many patients and represent a treatment challenge. Our results suggest that a combined ACL and ACI repair is a viable option in this group of patients and should reduce the anaesthetic and operative risks of a two-stage repair. Patients with complete rupture of ACL despite being deemed stable performed poorly at review and our study suggests all complete ruptures regardless of stability should be treated with a reconstruction when performing an autologous chondrocyte implantation

Introduction. There is a challenge to detect partial tear of the ACL, the number of bundle injured and the proportion of fibers torn. The MRI was shown efficient to individualize the two anteromedial (AM) and posterolateral (PL) bundles of the ACL. The purpose of this study was to assess the ability of the MRI to detect partial tears of the ACL on axial views to display the AM and PL bundles. Materials and methods. This retrospective study included 48 patients (19 partial tears of the ACL, 16 complete rupture of the ACL and 13 normal knee) who underwent both arthroscopy and MRI examinations of the knee. The conventional MRI protocol included one sagittal T1- weighted sequence and 3 proton-density fat sat. The images from MRI were analysis by a radiologist specialized in musculoskeletal imaging who was blinding to the arthroscopic findings. The criteria for the analysis of MRI were divided into primary (those involving the ACL himself) and secondary signs (associated abnormalities). The primary signs included the horizontalisation of the ACL (ACL axis), the global ACL signal intensity and the signal intensity of each AM and PL bundle. The secondary signs included bone bruise, osteochondral impaction, popliteus muscle injury, medial collateral ligament injury and joint effusion. The ACL was classified as normal, partially or totally torn. The rupture of the AM and PL bundle was specified. Results. In our study, MRI was found to have a 75% sensitivity and a 73% specificity for the diagnosis of partial tears of the ACL. The sensitivity to detect AM bundle lesion was 88% but the specificity was 50%. The lack of horizontalisation of the ACL was a very good sign, for partial tears of the ACL, with a sensitivity of 84% and a specificity of 81% (p<0.05). Regarding the secondary signs, there was no significant difference to distinguish partial and complete tear. However, we found that there was a greater probability to find a partial tear of the ACL with the lack of joint effusion, bone bruise and medial collateral ligament injury. Quantifying the proportion of injured fibers was unsuccessful and was found as a failure of the MRI. Conclusions. MRI exhibited lower sensitivity and specificity for partial tear than for complete rupture of the ACL. However 3 important arguments can guide us: the lack of horizontalisation of the ACL, a continuous ACL signal, the display of one of two bundles on the axial view

Objectives. The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. Methods. A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review. Results. The treatments of acute Achilles tendon rupture include operative and nonoperative treatments. Operative treatments mainly consist of open repair, percutaneous repair, mini-open repair, and augmentative repair. Traditional open repair has lower re-rupture rates with higher risks of complications. Percutaneous repair and mini-open repair show similar re-rupture rates but lower overall complication rates when compared with open repair. Percutaneous repair requires vigilance against nerve damage. Functional rehabilitation combining protected weight-bearing and early controlled motion can effectively reduce re-rupture rates with satisfactory outcomes. Biological adjuncts help accelerating tendon healing by adhering rupture ends or releasing highly complex pools of signalling factors. Conclusion. The optimum treatment for complete rupture remains controversial. Both mini-open repair and functional protocols are attractive alternatives, while biotherapy is a potential future development.

Assessment of the appropriateness of tendon transfer procedures and the necessity for excising the posterior tibial tendon (PTT) in stage II PTT dysfunction. 12 patients undergoing surgical treatment for unilateral PTT dysfunction underwent magnetic resonance imaging of the tibialis posterior (TP) and flexor digitorum longus (FDL) muscle bellies. All patients had atrophy of the TP muscle compared to the normal leg (mean 10.7%, p = 0.008). In those patients with a complete rupture of PTT there was replacement of the TP muscle by fatty infiltration. Conversely, the FDL muscle showed a compensatory hypertrophy (mean 17.2%, p< 0.002). Treatment of stage II posterior tibial tendon (PTT) dysfunction remains controversial. These findings support the use of FDL as the tendon of choice for augmentation of PTT in stage II disease. This study also demonstrates that in the presence of a complete rupture, excision of the PTT is a reasonable surgical procedure and pure tenodesis will fail because the TP muscle belly undergoes fatty infiltration. In patients with a diseased but intact PTT there was no fatty infiltration and the TP muscle volume was at least 83% of the normal side in all cases. We therefore suggest that in the presence of an intact PTT the TP muscle may provide some useful function if used to augment the FDL transfer when the diseased tendon is excised

Injury to the common peroneal nerve was present in 14 of 55 patients (25%) with dislocation of the knee. All underwent ligament reconstruction. The most common presenting direction of the dislocation was anterior or anteromedial with associated disruption of both cruciate ligaments and the posterolateral structures of the knee. Palsy of the common peroneal nerve was present in 14 of 34 (41%) of these patients. Complete rupture of the nerve was seen in four patients and a lesion in continuity in ten. Three patients with lesions in continuity, but with less than 7 cm of the nerve involved, had complete recovery within six to 18 months. In the remaining seven with more extensive lesions, two regained no motor function, and one had only MRC grade-2 function. Four patients regained some weak dorsiflexion or eversion (MRC grade 3 or 4). Some sensory recovery occurred in all seven of these patients, but was incomplete. In summary, complete recovery occurred in three (21%) and partial recovery of useful motor function in four (29%). In the other seven (50%) no useful motor or sensory function returned

Antegrade intramedullary nailing of fractures of the shaft of the humerus is reported to cause impairment of the shoulder joint. We have reviewed 33 patients with such fractures to assess how many had injuries to the ipsilateral shoulder. All had an MR scan of the shoulder within 11 days of injury. The unaffected shoulder was also scanned as a control. There was evidence of abnormality in 21 of the shoulders (63.6%) on the injured side; ten had bursitis of the subacromial space, five evidence of a partial tear of the rotator cuff, one a complete rupture of the supraspinatus tendon, four inflammatory changes in the acromioclavicular joint and one a fracture of the coracoid process. These injuries may contribute to pain and dysfunction of the shoulder following treatment, and their presence indicates that antegrade nailing is only partly, if at all, responsible for these symptoms

We have compared the results at a mean follow-up of 13 years (11 to 14) of two groups of supination-external rotation type-4 fractures of the ankle, in one of which there was a fracture of the medial malleolus and in the other the medial deltoid ligament had been partially or completely ruptured. Of 66 patients treated operatively between 1993 and 1997, 36 were available for follow-up. Arthroscopy had been performed in all patients pre-operatively to assess the extent of the intra-articular lesions. The American Orthopaedic Foot and Ankle Society hind-foot score was used for clinical evaluation and showed a significant difference in both the total and the functional scores (p < 0.05), but not in those for pain or alignment, in favour of the group with a damaged deltoid ligament (p < 0.05). The only significant difference between the groups on the short-form 36 quality-of-life score was for bodily pain, again in favour of the group with a damaged deltoid ligament. There was no significant difference between the groups in the subjective visual analogue scores or in the modified Kannus radiological score. Arthroscopically, there was a significant difference with an increased risk of loose bodies in the group with an intact deltoid ligament (p < 0.005), although there was no significant increased risk of deep cartilage lesions in the two groups. At a mean follow-up of 13 years after operative treatment of a supination-external rotation type-4 ankle fracture patients with partial or complete rupture of the medial deltoid ligament tended to have a better result than those with a medial malleolar fracture

The medial periosteal hinge plays a key role in fractures of the head of the humerus, offering mechanical support during and after reduction and maintaining perfusion of the head by the vessels in the posteromedial periosteum. We have investigated the biomechanical properties of the medial periosteum in fractures of the proximal humerus using a standard model in 20 fresh-frozen cadaver specimens comparable in age, gender and bone mineral density. After creating the fracture, we displaced the humeral head medial or lateral to the shaft with controlled force until complete disruption of the posteromedial periosteum was recorded. As the quality of periosteum might be affected by age and bone quality, the results were correlated with the age and the local bone mineral density of the specimens measured with quantitative CT. Periosteal rupture started at a mean displacement of 2.96 mm (. sd. 2.92) with a mean load of 100.9 N (. sd. 47.1). The mean maximum load of 111.4 N (. sd. 42.5) was reached at a mean displacement of 4.9 mm (. sd. 4.2). The periosteum was completely ruptured at a mean displacement of 34.4 mm (. sd. 11.1). There was no significant difference in the mean distance to complete rupture for medial (mean 35.8 mm (. sd. 13.8)) or lateral (mean 33.0 mm (. sd. 8.2)) displacement (p = 0.589). The mean bone mineral density was 0.111 g/cm. 3. (. sd. 0.035). A statistically significant but low correlation between bone mineral density and the maximum load uptake (r = 0.475, p = 0.034) was observed. This study showed that the posteromedial hinge is a mechanical structure capable of providing support for percutaneous reduction and stabilisation of a fracture by ligamentotaxis. Periosteal rupture started at a mean of about 3 mm and was completed by a mean displacement of just under 35 mm. The microvascular situation of the rupturing periosteum cannot be investigated with the current model

The February 2023 Shoulder & Elbow Roundup³⁶⁰ looks at: Arthroscopic capsular release or manipulation under anaesthesia for frozen shoulder?; Distal biceps repair through a single incision?; Distal biceps tendon ruptures: diagnostic strategy through physical examination; Postoperative multimodal opioid-sparing protocol vs standard opioid prescribing after knee or shoulder arthroscopy: a randomized clinical trial; Graft healing is more important than graft technique in massive rotator cuff tear; Subscapularis tenotomy versus peel after anatomic shoulder arthroplasty; Previous rotator cuff repair increases the risk of revision surgery for periprosthetic joint infection after reverse shoulder arthroplasty; Conservative versus operative treatment of acromial and scapular spine fractures following reverse total shoulder arthroplasty.

Aims

Avulsion of the proximal hamstring tendon origin can result in significant functional impairment, with surgical re-attachment of the tendons becoming an increasingly recognized treatment. The aim of this study was to assess the outcomes of surgical management of proximal hamstring tendon avulsions, and to compare the results between acute and chronic repairs, as well as between partial and complete injuries.

Injuries to the quadriceps muscle group are common in athletes performing high-speed running and kicking sports. The complex anatomy of the rectus femoris puts it at greatest risk of injury. There is variability in prognosis in the literature, with reinjury rates as high as 67% in the severe graded proximal tear. Studies have highlighted that athletes can reinjure after nonoperative management, and some benefit may be derived from surgical repair to restore function and return to sport (RTS). This injury is potentially career-threatening in the elite-level athlete, and we aim to highlight the key recent literature on interventions to restore strength and function to allow early RTS while reducing the risk of injury recurrence. This article reviews the optimal diagnostic strategies and classification of quadriceps injuries. We highlight the unique anatomy of each injury on MRI and the outcomes of both nonoperative and operative treatment, providing an evidence-based management framework for athletes.

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

Knee dislocation is a rare injury in high energy trauma, but it is even rarer in low energy injuries. We present, to our knowledge, the only case in the world literature of knee dislocation following a cricketing injury. The patient was a 46 year old recreational fast bowler who, whilst bowling, slipped on the pitch on the follow through. He sustained an anteromedial knee dislocation which was reduced under intravenous sedation. He also sustained a neuropraxia of the common peroneal nerve with grade 2 weakness of ankle and toe dorsiflexion. Magnetic Resonance Imaging (MRI) confirmed a complete rupture of anterior cruciate ligament (ACL), lateral collateral ligament (LCL) and postero-lateral corner (PLC). Patient underwent surgical reconstruction and repair of his PLC along with repair of LCL with combination of anchor sutures and metal staple within 72 hours of the injury. He was treated in a cast brace. The ACL insufficiency was treated conservatively. Patient made an uneventful recovery and follow up at 3 months revealed a full range of knee movements with asymptomatic ACL laxity

We report three complete ruptures and one partial rupture of the flexor pollicis longus tendon in association with the insertion of a volar plate for the treatment of fracture of the distal radius. Rupture was associated with the chronic use of steroids

1. Complete rupture of the axillary artery caused by dislocation of the shoulder in a man aged seventy-four is reported. There was severe arteriosclerosis and the simple operation of ligation of the artery was performed with success. There was excellent function of the shoulder and hand on review thirteen years later. 2. Previously recorded cases are reviewed

Ten cases of complete rupture of the collateral ligaments of the metacarpophalangeal finger joints are reported. The nature of this injury, the pre-operative morbidity and the intra-operative pathology are analysed. In all cases surgery was performed with satisfactory results. Operation is indicated for joint stability, grip and pinch strength, pain control and early functional recovery

1. Seventeen cases of knee injury are described in which the predominant lesion was rupture of the posterior cruciate ligament. Seven were treated conservatively and ten by surgical repair. 2. Most cases occurred in motor cyclists. 3. The extent of the rupture should be determined by examination under anaesthesia. 4. Early surgical repair is indicated for complete rupture. 5. An effective method of repair is described

Background. Acquired flatfoot deformity goes ahead with a partial or complete rupture and thus insufficiency of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medial displacement calcaneal osteotomy to reconstruct the acquired deformity. Material & Methods. Twenty two patients (24 feet) with an average age of 58 (36–75) years were operated on for acquired flexible flatfoot deformity. Two patients had a bilateral procedure. Patients were seen pre-and postoperatively in order to evaluate following parameters: AOFAS hindfoot score, visual analogue scale for pain (0–10), the tarsometatarsal angle on lateral and ap standing x-rays, the cuneiform heights and talocalcaneal angle on lateral standing x-rays and subjective postoperative satisfaction score (1-worst to 5-best). Average time of follow-up was 24.7 months (12–48). Results. The AOFAS hindfoot score could be increased from 46.4 to 89.5 points, the visual analogue scale for pain decreased from 6.6 to 1.1. The average satisfaction score was 4.5 points with one patient scoring 2 and another one scoring 3. All the other patients scored either 4 or 5. All radiological parameters could be improved. Following complications were seen: one recurrence, two patients with irritation of the sural nerve, one patient with hypesthesia of the big toe. The calcaneal screws had to be removed in 3 patients. Conclusion. Flexor digitorum longus transfer together with medial displacement calcaneal osteotomy gave satisfactory results for the treatment of acquired flatfoot deformity. All radiologic parameters were improved

Thirty-three consecutive patients with complete ruptures of the calcaneal tendon were treated by external fixation. The patients were assessed both objectively and subjectively, and the results classified as excellent, good, fair and poor. In 30 patients the result was excellent or good. There were no infections or re-ruptures. Two patients with fair results had sural nerve injury. The only patient with a poor result had Sudeck's atrophy. It is felt that this operation satisfies the need for a new technique which is simple and combines the advantages of both surgical and non-surgical treatment without their major complications

1. A case, believed to be the fifth on record, of supracondylar fracture with rupture of the brachial artery is described. 2. The relative immunity of the median nerve in these injuries is discussed, with brief reference to a recent case of complete rupture. Only a single previous report of this complication could be found. 3. It is suggested that these injuries are less uncommon than the number reported would indicate. 4. The anatomy of severe displacement is discussed, with special reference to the role of the brachialis. 5. The danger of closed reduction when the relationship of the upper fragment to the neurovascular bundle is in doubt is stressed. 6. The indications for open reduction are given

This is the largest detailed study of conservative management of Achilles tendon rupture in the literature to date. We assessed 140 subjects who had a complete rupture of their Achilles tendon treated with our combined conservative and orthotic regime between 1992 and 1998. Subjects were assessed subjectively and objectively, including isokinetic measurements of ankle plantarflexion and dorsiflexion. Overall 56% had excellent, 30% good, 12% fair and 2% poor results. The complication rate was 4%, with only 3 tendon reruptures. When compared with published results for operative repair, our combined conservative and orthotic treatment produces better results overall. Patients are subjectively happier, they have better strength results and have fewer complications

Closed rupture of the middle slip of the extensor hood of a finger is easily missed until the late appearance of a buttonhole deformity. Early diagnosis gives the best chance of satisfactory treatment, but Boyes' test becomes positive only at a late stage. A new test is described in which, from a 90 degree flexed position over the edge of a table, the patient tries to extend the proximal interphalangeal joint of the involved finger against resistance. The absence of extension force at the proximal joint and fixed extension at the distal joint are immediate signs of complete rupture of the central slip. The theoretical basis and the method of performing the test are discussed

Magnetic resonance imaging was performed on 28 patients with suspected calcaneal tendon injury prior to treatment. None of the patients were involved in competitive sports. All underwent clinical examination, some had had ultrasound or CT scans. We identified four types of lesions: type I, inflammatory reaction; type II, degenerative change; type III, incomplete rupture and type IV, complete rupture. Thirteen of the 28 patients underwent surgery and the diagnostic findings were verified. We recommend that type I, type II and type III lesions be managed conservatively, while type IV lesions should be operated in the young and active patient

In Essex-Lopresti injuries, the prevailing concept, according to which the stability of the forearm can be restored after fixation of the fracture or replacement of the radial head by a metallic implant, is disputable. The aim of this study is to evaluate the midterm results in 12 patients with an Essex-Lopresti injury who were treated operatively. We studied 12 patients, with comminuted fracture of the radial head, either isolated (4 patients) or with injury of the ipsilateral (4 patients) or the contralateral (4 patients) arm. Initially, 10 patients were treated with excision of the radial head whereas 2 underwent internal fixation of the radial head and pinning of the DRUJ. Eventually, everyone developed a subluxation of DRUJ and had to be treated for an established Essex-Lopresti injury, 1–7 months after the initial injury. Six patients were treated with equalization of the radioulnar length (ulnar shortening osteotomy with or without a distractor-external fixator) and restoration of the TFC, while six patients underwent replacement of the radial head with a titanium implant, equalization of the radioulnar length and restoration of the TFC. The results were evaluated after a mean follow-up of 4 years (1–12 years), based on radiological and clinical criteria. The six patients in whom the titanium radial head implant was used presented with good results, even though two of them reported forearm pain during activity. On the contrary, in the rest of the patients the radioulnar incongruity reappeared in varying degrees. However the poor radiological result was not consistent to the clinical one. We conclude that in cases of complete rupture of the interosseous membrane, internal fixation or replacement of the radial head with a metallic implant will not probably provide us with a good long-term functional result

In a prospective, randomised, multicentre study, 112 patients (99 men and 13 women, aged between 21 and 63 years) with acute, complete rupture of tendo Achillis were allocated either to surgical treatment followed by early functional rehabilitation, using a brace, or to non-surgical treatment, with plaster splintage for eight weeks. The period of follow-up was for two years. Evaluation was undertaken by independent observers and comprised interviews, clinical measurements, isokinetic muscle performance tests, heel-raise tests and an overall outcome score. The rate of rerupture was 20.8% after non-surgical and 1.7% after surgical treatment (p < 0.001). Surgical and non-surgical treatment produced equally good functional results if complications were avoided. However, the rate of rerupture after non-surgical treatment was unacceptably high

Aims: To determine the difference between macroscopic and microscopic appearances of the anterior cruciate ligament (ACL) in patients with osteoarthritis undergoing total knee replacement. Methods: Patients admitted for routine total knee replacement (TKR) for osteoarthritis were assessed. The integrity of the ACL was noted as normal, moderately damaged (fissured) or complete rupture on a macroscopic level at the time of surgery. The ACL was sacrificed as a normal step in the operation and sent for histological analysis. The macroscopic and microscopic findings of ACL histology were compared using a common grading system (Grade 1 = normal, Grade 2 = moderately diseased, Grade 3 = severely diseased). Results: The sample contained 48 patients, 17 male and 31 female, age range 55–87 years (mean 73). After exclusions, at surgery 7 ACL ruptures and 8 moderately diseased ligaments (defined by the presence of visible fissuring) were found despite negative pivot shift tests preoperatively. Of the 30 ACL’s that were found to be macroscopically normal, 22 of these (73%) were microscopically moderately or severely diseased. Conclusion: We have found that a macroscopically normal ACL does not necessarily equate to microscopic integrity in the presence of osteoarthritis. This is an important consideration given the current trend towards unicompartmental knee replacement and highlights the possible need for investigation with appropriate imaging (MRI) and arthroscopy prior to this specific surgery

Forty patients with acute complete rupture of the calcaneal tendon were managed conservatively and randomly allocated to treatment groups using either cast immobilisation for eight weeks, or cast immobilisation for three weeks, followed by controlled early mobilisation in a Sheffield splint. The splint is an ankle-foot orthosis which holds the ankle in 15 degrees of plantar flexion, but allows some movement at the metatarsophalangeal joints. It is removed to allow controlled movement during physiotherapy. Patients treated with the splint regained mobility significantly more quickly (p less than 0.001) and preferred the splint to the plaster cast. The range of dorsiflexion at the ankle improved more rapidly after treatment in the splint (p less than 0.001), and patients were able to return to normal activities sooner. Recovery of the power of plantar flexion was similar in the two treatment groups, and no patient had excessive lengthening of the tendon. One re-rupture occurred in each group

1. Radiographs of both shoulders were performed on 106 unselected necropsy subjects and those found to be abnormal were examined pathologically. 2. Radiological abnormalities were found in sixty-eight shoulders of thirty-eight subjects. Pathological examination showed rotator cuff tears and associated abnormalities in thirty-five of these, rheumatoid arthritis in one, a previous fracture in one, and one was not examined. 3. The criteria for radiological diagnosis of rotator cuff tears are examined and discussed. 4. The radiological changes give little indication of the severity of the tears or associated abnormalities except in the case of complete rupture of the cuff when acromio-humeral articulation occurs. 5. The lesions are all explicable on a traumatic basis. There is no correlation with the presence or absence of osteoarthritic disease of the joint. 6. The biceps tendon may become damaged or even ruptured in this condition. 7. Villous synovial proliferation was found in fourteen cases, in five of which it was pigmented with histological appearances resembling pigmented villonodular synovitis. The significance of this finding is briefly discussed

Introduction: Acute Achilles tendon rupture is very much associated with sports practice and it’s a common lesion between young people. Despite of much Discussion: in the literature, the correct treatment of the complete ruptures of this tendon in the acute phase remains controversial. The objective of this work is to accomplish a comparative analysis between the results obtained with both techniques: open versus percutaneous. Materials and Methods: This work included 81 patients (6 women e 75 men) with acute rupture of the Achilles tendon between January of 1999 and December of 2008 and that were submitted 51 to surgical treatment with open technique and 30 with the percutaneous with the technique of Ma and Griffith modified. This patients had medium age of 35,6 years with a greater incidence between 30 and 39 years and with medium time follow-up of 1,9 years. The diagnostic of the lesion was based in clinic criteria and when there was a doubt an ecography was realized. In both Methods: was used posteoperative cast immobilization with 20° of plantar flexion during 6 weeks. The patients were analysed according to clinical e functional evaluations and the American Orthopaedic Foot and Ankle Society scale and the Holtz score. Results: The patients included in the percutaneous group had better functional results with more precocious weight bearing, better ankle range of movement e more earlier return to sports practice (p< 0,001). In the open technique there were more complications in comparison with the percutaneous one (15,7% vs 6,7%). In the open technique there were no rerupture and in the percutaneous technique there were 6. The results in both scales were better in the percutaneous group but it wasn’t statistically significative. Discussion: Good functional results and a low percentage of complications recommend the use of surgical techniques in the treatment of this disease. Better functional and aesthetic results were obtained in the percutaneous group but at expense of a more percentage of reruptures. Open surgery is indicated in the reruptures after the utilisation of the percutaneous technique

Don O’Donoghue (1950) described a particular acute injury of the knee in athletes (“also of high school age”) that he described as “an unhappy triad”. It consisted of: 1) rupture of the Medial Collateral Ligament (MCL), 2) damage to the Medial Meniscus (MM) and 3) rupture of the Anterior Cruciate Ligament (ACL). We have reviewed the arthroscopic findings of 34 consecutive knees (ages 12 to 16 years) with complete rupture of the ACL. In 21 cases the injury was acute, and the remaining were chronic of had had more than one traumatic episode at the time of arthroscopy. Out of the 34 cases, 26 had associated meniscal injuries: 4 MM; 14 Lateral Meniscus (LM) and 8 MM plus LM. Acute ACL injuries were associated mainly with LM damage (MM/LM: 1/5) whereas, in the chronic injuries, there were no such differences (MM/LM: 1/1). Out of the 21 acute LCA injuries there were 17 cases of acute rupture of the MCL. Conclusions: 1- Contrary to what has been widely accepted, also in pre-adolescent and adolescent, Acute ACL ruptures are more frequently associated with LM damage that with MM tears. 2- Most injuries of the MM associated to ACL injuries (particularly “bucket handle” tears) are the result of a previously ACL unstable knee

Aims

The aim of this prospective study was to assess the long-term clinical, radiological, functional, and quality of life (QoL)-related outcome of patients treated with the synthetic Ligament Advanced Reinforcement System (LARS) device for anterior cruciate ligament (ACL) rupture.

To investigate the diagnostic properties of magnetic resonance imaging (MRI) scans in detecting surgically verified disruptions of the cervical intervertebral disc and anterior (ALL) and posterior longitudinal (PLL) ligaments. Data were extracted from the reports of cervical spine MRI scans of patients who subsequently underwent surgical stabilization for presumed instability following disco-ligamentous injuries of the cervical spine. The level and severity of disc, ALL and PLL disruption was compared with surgical findings. Unweighted kappa statistics were used to assess agreement. The sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated after findings where dichotomised into complete rupture, yes/no. Sensitivity analyses were performed to account for missing data. The MRI and surgical findings were compared on 31 consecutive patients. The kappa values for intervertebral disc disruption, ALL and PLL disruption were 0.22, 0.25 and 0.31 respectively, indicating fair agreement. Sensitivity, specificity, PPV and NPV are shown in Table 1. The false negative rates for diagnosing complete disruption of the disc, ALL and PLL were 0.18, 0.40 and 0.14 respectively. The ability of cervical MRI scans to detect surgically verified disruptions of the intervertebral disc, ALL and PLL varied depending on the structure examined. In this series, the cervical MRI scan reliably detected disruption of the intervertebral disc disruption and ALL. The false negative rates are of concern and indicate the need for additional investigations to exclude instability in the absence of negative MRI findings

Introduction In this institution a structured program of conservative management of Achilles tendon rupture has been developed combining a conservative and orthotic treatment regime with a view to adding the advantages of a removable orthosis to traditional non-operative therapy. This study compares the results of this protocol to published surgical results. This is the largest detailed study of conservative management of Achilles tendon rupture in the literature to date. Methods We assessed 140 subjects who had a complete rupture of their Achilles tendon treated with our combined conservative and orthotic regime between 1992 and 1998. Subjective assessments of symptoms and objective measurements of ankle range of motion, calf circumference and isokinetic measurements of ankle plantar flexion and dorsi flexion were recorded. Patients also completed a functional heel-rise test. Our results have been compared to published series. Results Our overall results showed 56% had excellent, 30% good, 12% fair and two percent poor results. The overall complication rate was four percent, with three tendon reruptures. When compared with published results for operative repair, our combined conservative and orthotic treatment produces better results overall. Patients are subjectively happier, they have better strength results and have fewer complications. In relation to the conduct of this study, one or more of the authors is in receipt of a research grant from a non-commercial source

Introduction. The Segond's fracture is described as a cortical avulsion of the lateral tibial plateau at the site of insertion of the middle third of the lateral capsular ligament. The Segond's fracture is usually associated with a tear of the Anterior Cruciate Ligament (ACL) and it is considered as an indirect radiological sign of complete rupture of the ACL. However there are no studies investigating the effect of a Segond's fracture on the kinematic of the knee especially on the rotatory instability and Pivot Shift (PS) phenomenon. The purpose of this study is to investigate the effect of a Segond's fracture on the kinematic of the knee with the use of navigation and the PS test. Methods. Ten whole fresh-frozen cadavers were used. A navigator (2.0 Orthopilot Navigation System, BBraun Aesculap, Tuttlingen, Germany) was used to measure maximum manual Anterior Tibial Translation (ATT) at 30°, 60° and 90° of flexion, maximum manual Internal Rotation (IR) and maximum manual External Rotation (ER) at 0°, 15°, 30°, 45° and 90° of flexion. All procedures were performed three times and the mean value taken as the final result in each case. Moreover a PS test was performed by the senior, most experienced, surgeon, and graded as mild (gliding), moderate (jerk) and severe (subluxation). Navigation measurements and PS tests were performed in each knee with ACL intact, after arthroscopic cutting of the entire ACL and after a Segond's fracure was produced by exposing the antero lateral compartment of the knee underneath the ileo-tibial tract. Statistical analysis was performed using ANOVA 1-way and MANOVA tests and value for statistical analysis was set at p<0.05. Results. Navigation procedure: Cutting the whole ACL resulted in a significant increase of ATT at 30° and 60° of flexion, with no significant effect on IR and ER. Producing the Segond's fracure resulted in a significant increase of ATT at 60° and 90° of flexion, in a significant increase of IR at 30°, 45° and 60° of flexion with no significant effect on ER. PS: The PS was clinically undetectable in all knees with ACL intact. After cutting the ACL it continued to be undetectable in two cases, mild positive in six cases and moderate in two. The addition of the Segond's fracture resulted in an increase of the PS in all cases with a moderate grade detected in three and severe in seven. Conclusions. Despite the limitations of this study, which include manual loads applied to the knee during navigation measurements and subjective evaluation of the PS, the results of this cadaver study indicate that the Segond's fracture has a significant effect on knee stability especially on rotational stability, which is functionally the most important in case of ACL tear. Therefore, in case of an acute ACL tear, when a Segond's fracture is radiologically detected and an ACL reconstruction is performed, an inspection of the lateral compartment with repair of capsule and fixation of the fracture could be advisable in order to better restore knee stability

Aims

The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes.

Complete rupture of the Achilles tendon is a well described injury. Assessment of outcome and rehabilitation post surgery is difficult to qualify objectively. We undertook a prospective evaluation of patients who had surgical repair of their ruptured Achilles tendon at our institution over a five year period. All patients underwent clinical and functional assessment. Objective function was evaluated using isokinetic testing on a Biodex dynamometer. Measurements included peak torque/body weight, average power, deficits, total work and range of movement. Studies were repeated at 60, 120 and 240 degrees/second. This was correlated with average time off work and time of return and level of sporting activities. Although 53 patients were entered into the study, only 24 returned for full isokinetic testing. Males (16) were more commonly affected than females (9). Peak incidence was in the fourth and fifth decades of life. Mean hospital stay was 1.8 days. There were no problems with wound healing, and there were no infections. 22 of 25 patients returned to their pre-injury level of activity after an average of 6 months. Time off work averaged 14 weeks. 16 of 25 patients were the same or better when comparing peak torque/body weight, average power, maximum average peak torque and total work/body weight when compared with the unaffected limb. Rehabilitation following Achilles tendon repair can be monitored clinically, however isokinetic testing can provide a more objective assessment of progress

Operative release for entrapment of the suprascapular nerve was carried out in 35 patients. They were assessed at an average of 30 months (12 to 98) after operation using the functional shoulder score devised by Constant and Murley. The average age at the time of surgery was 40 years (17 to 67). Entrapment was due to injury in ten patients and no cause was found in three; 34 had diffuse posterolateral shoulder pain. The strength of abduction was reduced in all the patients. The average Constant score, unadjusted for age or gender, before operative release was 47% (28 to 53). In 25 of the patients both the supraspinatus and infraspinatus muscles were atrophied and seven had isolated atrophy of the infraspinatus muscle. The average conduction time from Erb’s point to the supraspinatus muscle and to the infraspinatus muscle was 5.7 ms (2.8 to 12.8) and 7.4 ms (3.4 to 13.4), respectively. In two patients MRI revealed a ganglion in the infraspinatus fossa and, in another, a complete rupture of the rotator cuff. The average time from the onset of symptoms to operation was ten months (3 to 36). A posterior approach was advocated. The average Constant score, after operative release, unadjusted for age or gender was 77% (35 to 91). The overall result was excellent in ten of the patients, very good in seven, good in 14, fair in two, and poor in two. The symptomatic and functional outcome in our series confirmed the usefulness and safety of operative decompression for entrapment of the suprascapular nerve

Rotator cuff or long head of biceps tendon tears are common in patients with degenerative shoulder rotator cuff disease. Most often they are investigated with an MRI scan. Diagnosis prior to surgery is useful for the appropriate surgical planning. We present 63 consecutive patients who had arthroscopic shoulder surgery and prior to that had MRI investigation between 1994 and 2001. Their medical records were reviewed; arthroscopic operative findings as well as the report of the MRI scan were recorded and compared retrospectively. The aim of our study was to assess the accuracy of MRI findings comparing the arthroscopic ones regarding rotator cuff and biceps tendon pathology. There were 63 patients with mean age 58 years. All of these had MRI scan investigation and the waiting time prior to surgery was 10 months. It was found that there were 6 false (−)ve, 1 false (+)ve and two cases with full thickness cuff tears which were reported as probable tears. Further to that, there were 11 frayed biceps tendons, 8 partially ruptured, 3 subluxed, 4 complete ruptures and 1 SLAP lesion. All biceps lesions were not commented in the MRI scan reports. MRI scan is very sensitive detecting soft tissue pathology in shoulder investigation. However, even on that basis, rotator cuff and in particular biceps tendon pathology can be missed. The shoulder arthroscopy is the best method to accurately diagnose those lesions. However, it should be noted that often the surgeon has got to alter to working surgical plan in order to address the problem intraoperatively. In this study it is demonstrated the MRI scan often misses rotator cuff or long head of biceps tendon pathology. The most sensitive method for the diagnosis of it is the shoulder arthroscopy, which address its treatment in the same time

Introduction: Management of acute rupture of the Achilles tendon is controversial. Conservative treatment has a higher re-rupture rate while surgery has complications like infection and wound breakdown. We devised a protocol in our hospital to decide between the surgical or non-surgical options. At our institution, a well-documented and structured program of non-operative or opeartive management of Achilles tendon rupture with use of either casts or operation has been devised based on Ultrasound findings of the ‘Gap/distance between the two ends of the Tear’. PURPOSE: The purpose of this study was to compare the incidence of Re-rupture in those treated by cast immobilization where the ends were approximating at ultrasound examination at our institution. METHODS: This study Prospectively assessed the results in 50 consecutive patients with a complete rupture of the Achilles tendon who had been treated with our regimen depending on the findings of the ultrasound examination, between 2003 and 2006. All ruptured Tendoachilles had ultrasound done in Full Equinus position to assess whether the ends are approximating or not. If ends were approximating they were treated in an equinus cast. Patients were evaluated on the basis of the subjective results and functional outcome measure, along with validated visual analogue scores. Re-rupture rates were measured at 06 months after injury. There were 35 Male and 13 females. This was followed by a final questionnaire to assess their return to pre-injury activities. Two patients were lost to follow-up as they moved out of the area. RESULTS: All the 48 re-ruptures available for analysis had their ultrasound done on initial presentation. 25 were treated non-operatively and 23 underwent surgery. The overall complication rate for Non Operative was minimal, with NO re-rupture or documented deep vein thromboses. In operative group there were 2 re-ruptures, 5 postoperative infection and discharge. CONCLUSION: The results of our non-operative treatment were better overall than published results of non operative & operative repair of acute Achilles tendon rupture. In this study the ends are approximating, confirmed on ultrasound before being assigned to Cast Immobilization. SIGNIFICANCE: The previous studies have not assigned patients into operative or non-operative groups based on whether the ends are approximating in full equines position. By assigning only those in whom the ends are approximating, to cast immobilization, re-rupture rates are less, thus resulting in better and stronger healing of TAs’ and avoiding risks of surgery

Purpose: Anatomic repair of an acute distal biceps tear has been demonstrated to improve flexion and supination strength compared with conservative treatment. The most commonly used fixation methods for a distal biceps tendon repair include suture anchors, bioabsorbable screws, and endobutton. The goal of this study was to. perform a radiologic evaluation of bioabsorbable screw tunnel osteolysis and. retrospectively review bioabsorbable-screw related clinical complications. Method: We included twenty (20) consecutive patients who underwent primary anatomic repair of the distal biceps tendon since 2005. We used a 7x23mm biote-nodesis. ®. screw (Arthrex) in 18 cases, and 8x23mm and 8x12mm screws in the other two cases. First, from the x-ray view done in the immediate postoperative period showing the complete screw tunnel, we measured the ratio of the volume of the bone tunnel to the volume of the radius bone section. A mathematical formula for cylindrical volume was used (¶ x r2 x h). We used a relation between two volumes rather than the tunnel volume itself for scaling purposes. Secondly, we calculated the same relation on the x-ray from the last follow-up. We then obtained the percentage of tunnel enlargement by relating the volumetric ratio from the first x-ray to the ratio from the last x-ray. Afterwards, we performed a retrospective chart review noting any bioabsorbable screw-related and postoperative complications. Results: In the group, the average age was forty-six (46) years. All subjects were male. Eighteen (18) cases were acute complete ruptures operated in the first three weeks, one case was a partial rupture and one case was chronic (one year). The average follow up was eighteen (18) months. We found that the average initial relative volume occupied by the screw tunnel was 47 % of the bone section. At the last follow-up, this volume increased to 68%. After our chart review, we found that one patient presented with a broken screw and increased pain and that another patient developed a severe foreign-body reaction with re-rupture of the tendon requiring three reoperations. Conclusion: The use of a bioabsorbable screw for distal biceps tendon fixation results in significant osteolysis of the radial bone at short term follow-up. Consequences of osteolysis in the radius are worrisome since iatro-genic fractures are more likely to occur. Osteolysis can be secondary to an inflammatory reaction to the screw material, bone necrosis secondary to pressure or initial thermal necrosis. We also noted two cases of severe bio-tenodesis screw-related complications among our series of twenty (20) patients. These results call into question the use of the bioabsorbable screw in distal biceps tendon repair and are important to present. Exact volume of bone loss using 3D computed tomography scan analysis as well as quality of life questionnaires and strength testing will be available for presentation

The purpose of this study was to investigate the functional outcome of a group of patients following completely neglected tendo-achilles ruptures. Between July 2001 and July 2002 we identified 6 patients who presented to the Foot and Ankle Service in Oxford with 7 chronic untreated complete ruptures of the tendo-achilles. There were 4 males and 2 females and the average age was 65 years (range 52 to 79). The average time since injury was 12.2 months (range 7 to 24). None of them had undergone any modality of treatment for this condition. From the history, a definite acute injury was confirmed in each patient. All patients had a palpable defect in the tendo-achilles between 4 and 8 cm from the insertion and the defects measured from 10 to 32 mm. In all case the Thompson test confirmed ongoing discontinuity and single leg heel raise was not possible on the affected side. Each patient was assessed using the scoring system of Leppilahti and concentric and eccentric power were assessed using the Kin-Com Dynamometer. The results indicate an average Leppilahti score of 65/100 with 1 excellent, 0 good, 3 fair and 2 poor. The isokinetic strength measurements demonstrated that plantar flexor power was on average 36% weaker than the normal side. These differences were most marked at the higher test speeds, which were on average 16% weaker than at the lowest test speed in the affected leg. Five out of 6 patients were pain free, with only one reporting mild pain. Objective testing demonstrated no differences in the range of movement between the injured and the normal side. All patients were satisfied with the outcome; however, most had some reservations, which related to ongoing weakness that prevented recreational activity. Conclusion: At one year after injury the completely neglected tendo-achilles rupture in the older population is likely to be pain-free, to have full active ankle movement and to recover two-thirds of the power of plantar flexion compared to the unaffected limb. Ongoing weakness will prevent recreational activity but has minimal affect on activities of daily living including stair-climbing ability. We have established a benchmark of the natural history of this condition in the older patient against which the results of surgical treatment can be compared

Introduction and Aims: Knee dislocation is an uncommon but serious injury. This study assessed the initial mechanism of injury, pattern of ligament injury, osteochondral and peri-articular soft-tissue trauma, and associated neurovascular injuries in the multi-ligament knee injury. Outcomes following operative and non-operative management were reviewed. Method: Retrospective review of patients with multi-ligament knee injuries was performed. Inclusion criteria were either a confirmed knee dislocation, or complete rupture of two or more ligaments requiring reconstruction. Systematic review of hospital records and imaging was performed for all patients, and clinical assessment, including validated outcome scores, were performed in the majority of patients. All reconstructive surgery was performed by the two senior authors. Results: Forty-five patients with 47 knee injuries were identified over a 13-year period (1990–2003). The most common mechanisms of injury were motorcycle and motor vehicle accidents. Other mechanisms included pedestrians hit by cars, sporting injuries and falls. Approximately half had a documented knee dislocation, while the remainder were located at the time of presentation. Vascular injury occurred in around 25% of patients, all having positive clinical findings. Routine angiography was not performed in the absence of positive clinical findings. Neurological injury also occurred in approximately 20% of patients. Transient neuropraxia was more common than permanent nerve palsy, and there was an association between neurological and vascular injury. Associated injuries were varied, the most frequent being long-bone fracture. A significant number of patients had no associated injuries. Injury patterns were varied, though correlations were found between the reported mechanism and the pattern of ligament rupture and osteochondral injury. The majority of cases were managed with operative repair, and assessment of outcomes revealed that most returned to a good level of function, with some minor objective residual laxity and/or stiffness. Conclusion: Multi-ligament injuries of the knee are uncommon but serious injuries with potentially catastrophic consequences. This detailed analysis provides correlation between mechanism and resulting injury to the knee and periarticular structures. The analysis of this large series provides valuable information to better understand natural history, and improve future management

Aim: The accuracy of joint line tenderness (JLT) and magnetic resonance imaging (MRI) were determined in the diagnosis of meniscal tears in patients with complete rupture of the anterior cruciate ligament (ACL). Additionally, the effects of time from injury (to arthroscopy) and medial femoral condyle (MFC) lesions on diagnosis with JTL and MRI were established. Methods: A total of 133 male patients, whose first arthroscopy was performed by MU, were included. Preoperative MRI findings, the initial knee trauma causing ACL rupture, and the time from injury (TFI) were recorded. Physical examinations including JLT were performed within 1 week preceding the operation by the same observer. MRIs were performed within 6 weeks preoperatively by a 1.5 T imager. The first 6 week period after the initial trauma was defined as the acute (Grup I), 6 weeks to 12 months as the subchronic (Grup II) and 12 months or longer as the chronic period (Grup III). The sensitivity, specificity, and accuracy for JLT and MRI were calculated. Retrospective analyses were performed for TFI. Chi-square and kappa (k) tests were used for statistical analyses. Results: In all patients, mean TFI was calculated as 14.8±16.8 months (median; 8.0). Patient distribution were as follows; 29(21.8%) were Group I, 51(38.3%) Group II, and 53(39.8%) Group III. The sensitivity, specificity, and accuracy of MRI were 89.1%, 87.0%, and 87.9% for MML (p=0.0001,k=0.76), while 91.6%, 74.6%, and 82.7% for LML (p=0.0001,k=0.66), respectively. The sensitivity, specificity, and accuracy of JLT independent from TFI were 66.2%, 76.8%, and 70.7% for MML (p=0.0001,k=0.42), while 59.4%, 67.2%, and 63.2% for LML (p=0.002,k=0.27), respectively. For MML, the accuracy values of Groups I and III were; 86.2% (k=0.72) and 88.7% (k=0.76) for MRI (p=0.0001) and 55.2% (p=0.363, k=0.13) and 77.4% (p=0.0001,k=0.51) for JLT, respectively. For LML these were 75.9% (p=0.007,k=0.51,) and 90.6% (p=0.0001,k=0.81) for MRI and 48.3% (p=0.604,k=0.02) and 71.7% (p=0.002,k=0.43) for JLT, respectively. In Group III, diagnostic accuracy of JLT for MML was 80.0% (p=0.003,k=0.57) in the absence of MFC lesions and decreased to 73.9% (p=0.035,k=0.44) in their presence. In chronic MML, rate of false positive results of JLT in the presence and absence of MFC lesions was 21.7% and 10.0%, respectively (p=0.237). Conclusion: The accuracy of MRI and JLT in LML was lower than MML, especially in the acute period. In the diagnosis of acute and subchronic LML, and acute MML, use of JTL was not statistically significant. However, in determination of MML, the presence of MFC lesions particularly in the chronic period, lead to a 2-fold increase in the rate of false positive results in terms of diagnosis with JTL

Aim: The biceps brachii is an important elbow flexor and is the main supinator of the forearm. Avulsion of its distal tendon insertion is an uncommon injury and even more uncommon is the partial tear of this tendon. The rupture typically occurs at its attachment to the radial tuberosity. Nonoperative treatment of these injuries has been described, but significant weakness in flexion and supination or persistent pain may occur. Most authors recommend acute anatomic repair to improve function or relieve pain. Material and Method: Twenty-five ruptures of the distal biceps tendon were operated at our institution from 1992 to 1997. Twenty-three of the patients were male and 2 female. The dominant extremity was involved in 21 patients. Their average age was 48 years (range, 30–59). Eighteen ruptures were complete, 8 of them were acute, while 10 were chronic, as were the 7 partial ruptures. Three patients with complete rupture and all the patients with partial rupture had a MRI. In 2 chronic patients an anatomic repair was impossible and they were treated with a biceps-to-brachialis transfer. These patients were not included in the final follow-up. All other tendons were repaired anatomically through use of a single anterior incision and bone suture anchors. Follow-up averaged 36 months (range, 12–53 months). At final follow-up subjective and objective data were collected. Patients were questioned about their activity level, job status, and satisfaction at outcome. Elbow range of motion, strength and power were compared with those for the uninjured side while each value was adjusted for dominance and expressed as a percentage of the uninjured side. Results: All patients returned to their preinjury level of activity and employment by 6 months after surgery. All patients reported that they were satisfied with the result and would undergo the surgery again. The entire group of patients averaged 9.8% more flexion strength and 2.4% less supination strength for the repaired elbow that for the uninvolved elbow. Range of motion was normal in 20 patients. Three patients lacked 10° of extension and one of them lacked 10° of pronation. No patient experienced transient or permanent nerve deficit. None of the patients complained of pain or tenderness. There was no evidence of heterotopic ossification or change in the position of the suture anchors. Conclusion: The one incision technique with bone suture anchors is a safe and reliable technique for the treatment of complete or partial distal biceps tendon ruptures with very good results referring to restoration of flexion and supination strength and minimal complication rate

Aims

Functional rehabilitation has become an increasingly popular treatment for Achilles tendon rupture (ATR), providing comparably low re-rupture rates to surgery, while avoiding risks of surgical complications. Limited evidence exists on whether gap size should affect patient selection for this treatment option. The aim of this study was to assess if size of gap between ruptured tendon ends affects patient-reported outcome following ATR treated with functional rehabilitation.

Aims

The purpose of this study was to identify the changes in untreated long head of the biceps brachii tendon (LHBT) after a rotator cuff tear and to evaluate the factors related to the changes.

Complications of distal radius fractures range from 20 to 30% and are consequence of injury or of treatment. Management of these complications must be individualised and the multitude of proposal treatments prove that this problem is controversial. Complications may involve soft tissue (tendon, nerve, arterial or fascial complication, reflex symphatetic distrophy) or bone and joint (malunion, nonunion, osteoarthritis). Tendon complications following distal radius fractures, range from minor adhesions to complete rupture. Peritendinous adhesions will become apparent after cast removal. Diagnosis is based on the limitation of the range of movement for individual fingers.This complication can be avoided with a proper cast technique allowing full range of motion to the digits. Treatment consists of rehabilitation techniques and only rarely, in severe cases, operative tenolysis may be a treatment of choice. Tendons may be entrapped either in the fracture site or in the distal radioulnar joint. Most common tendon entrapment are for extensor carpi ulnaris and extensor digiti minimi. If early recognition is made, open reduction with freeing the tendon must be the choice. Late diagnosis will require more complex tenolysis procedures. Tendon rupture may occur at the time of injury due to sharp fracture fragments. Diagnosis is based on identification of functional loss and, whenever possible, primary tendon suture is recommended. If the diagnosis is late the treatment is free tendon graft or tendon transfer. The late rupture of extensor pollicis longus is the most common possibility. Since it is not related with comminution or displacement of fracture it is possible that an ischemic mechanism is involved. Solutions are free tendon graft or the transfer of extensor indicis proprius. Direct tendon repair is not recommended after few weeks. Nerve complications. Careful neurological investigations demonstrated that nerve injuries associated with distal radius fractures are more common than it is believed. Median nerve is most frequently involved. Primary mechanisms of injury are: direct lesions due to fracture fragments, lesions related to forced manipulation and nonanatomical position of immobilization. Late injuries, occurring a long time after the fracture are more frequent and are related to carpal tunnel syndrome or paraneural adhesions. Carpal tunnel pressure could be measured and ethiologic factors must be identificated in order to establish the proper treatment, usually based on relise of carpal tunnel. Ulnar and radial neuropathy are less common and treatment may vary from cast removal to relise of Guyon’s canal. Vascular complications are uncommon, arise usually in relation with high energy trauma and the treatment is complex, involving different speciality surgeons. Some authors presented rare cases of entrapment of vasculare structures or radial artery pseudoaneurism after the use a volar plate. Compartment syndrome after distal radius fracture is rare and is likely to occur in young adults suffering a high energy trauma. Clinical diagnosis is based on the classical 5 “P’s” (pain, pallor, paresthesias, paralysis, and pulselessness) but treatment must start before all symptoms are present. Anytime when compartment syndrome is suspected, intracompartimental pressure must be measured. The treatment must start immediately and consist in removal of constrictive devices (bandage, cast) and fasciotomy. Indications for fasciotomy are intracompartmental pressure of 15–25mmHg in presence of clinical signs or over 25mmHg in absence of clinical signs. If there is doubt, it is better to perform an unnecessary fasciotomy than to wait until lesions becomes irreversible. Reflex sympathetic distrophy is described with many terms such as algodistrophy, cauzalgia, Sûdeck’s atrophy, shoulder-hand syndrome. Recently, the term complex regional pain syndrome was proposed to replace all the exiting synonyms. Despite many theories, the pathogeny of this disease is uncertain. The diagnosis is mainly clinical, based on presence of pain, trophic changes (atrophy, stiffness, edema) and functional impairment but plain x-ray demonstrating osteopenia and bone scintigraphy showing abnormal bone turnover may be helpful. Since the patogeny is unclear, the treatment is targeting the symptoms rather then the disease. Treatment must be individualized and may consist of: physical therapy of the hand, pain control with general or local drugs, corticosteroids, and symphatectomy. Prevention of reflex symphatetic dystrophy in the first days of a distal radial fracture is very important and include: prevention of the edema (elevation of the hand, early mobilization of fingers), decrease of pain, cast removal to relive pression, non-traumatic surgery. Malunion is the most common complication of distal radius fracture and it usually occurs after close treatment. The malalignament may be extraarticular or it may involve the joint (radiocarpal or distal radioulnar joint). Axial shortening and dorsal or radial malalignament are the most common. Clinical signs are wrist pain, loss of grip strength, limitation of wrist mobility. Osteoarthritis is likely to develop in both types of malunions. For extraarticular nonunions osteotomy is usually the treatment of choice. Many types of osteotomies have been proposed but the most commonly used are opening wedge osteotomy and Watson osteotomy. Intraarticular malunion is more difficult to treat and many surgical solutions have been proposed: intraarticular osteotomy, bone resections (styloid, anterior or posterior rim, radiolunate or radioscapholunate limited arthrodesis, proximal row carpectomy, wrist denervation, wrist arthroplasty, total wrist arthrodesis). Salvage procedures on the distal radioulnar joint may be resection of distal cubitus (Darrach) or Sauve-Kapandji technique. Nonunion is an extremely rare complication and is likely to occur in patients with multiple comorbid conditions such as diabetes, peripheral vascular disease or alcoholism. In most cases the initial treatment was close reduction and cast immobilization or external fixation. Diagnosis is based on the absence of radiographic signs of union at 6 months. Treatment must be individualized but basic options are reconstructive procedures or wrist arthrodesis. Reconstructive procedures consist of debridement of nonunion site, realignment with distractor, plate and screw fixation and iliac crest bone grafting. Since the bone is of poor-quality, new implants providing fixation in orthogonal planes may be useful. Usually, malalignement is present, so some authors recommend to take in to consideration the possibility to associate reconstructive procedures with additional techniques such as: dividing brachioradialis tendon, incision of the dorsal or volar joint capsule or Darrach operation in presence of severe shortening of the radius. Wrist arthrodesis should be chosen when the distal fragment has less then 5 millimeters of subchondral bone supporting the articular surface

Aims

Despite the increase in the surgical repair of proximal hamstring tears, there exists a lack of consensus in the optimal timing for surgery. There is also disagreement on how partial tears managed surgically compare with complete tears repaired surgically. This study aims to compare the mid-term functional outcomes in, and operating time required for, complete and partial proximal hamstring avulsions, that are repaired both acutely and chronically.

Aims

The aim of the Scaphoid Magnetic Resonance Imaging in Trauma (SMaRT) trial was to evaluate the clinical and cost implications of using immediate MRI in the acute management of patients with a suspected fracture of the scaphoid with negative radiographs.

Aims: The purpose of this study was to verify a partial bursal-side rupture of the rotator cuff (RC) using different imaging techniques with special emphasis on the validity of a specific method of subacromial arthrography (SAA). Methods: Patients (n=92, age 53.8 years) with a subacromial impingement syndrome underwent sonography, magnetic resonance imaging (MRI), and SAA. All diagnostic results were controlled by subsequent arthroscopic surgery. Results: Out of 31 surgically verified ruptures, 17 cases showed a partial rupture located towards the bursa. These had been detected by MRI and ultrasound with a sensitivity of 64% and 41%, respectively, while SAA as a diagnostic tool yielded a sensitivity of 82%. In 14 cases of complete RC ruptures, all imaging techniques had a similar sensitivity of 86 to 93%. Conclusions: It appears that SAA is a sufficient and valid diagnostic tool for the detection of partial bursa-sided RC ruptures. Ultrasound and MRI showed a comparably lower sensitivity. It is therefore concluded that SAA has clear advantages in the diagnosis of this defect with the consequence that open surgical techniques to the patient can be avoided

Introduction: Achilles tendon (AT) rupture is a common sports injury. However, about 10% to 25% of the complete AT ruptures are not diagnosed. The management of neglected or chronic AT ruptures is usually different from that of acute rupture as the tendon ends were retracted and atrophied with short fibrous distal stumps. In the current series, we reported the mid- to long-term outcome of 10 patients with neglected or chronic AT rupture managed by a modified Flexor Hallucis Longus (FHL) transfer. Materials and Methods: Between April 2002 and December 2003, 10 patients (6 males, 4 females) were operated on for a neglected or chronic AT rupture with a FHL transfer. The age at surgery averaged 44.1 years (range, 27–70). Five patients presented with a neglected AT rupture, 3 with a chronic AT rupture associated with Achilles tendinosis and 2 with an AT re-rupture. The AT defect after fibrosis debridement averaged 7.4 cm (range, 2.5–10). Beside FHL transfer, we performed a transfer augmentation with the 2 remaining Achilles fibrosis flaps. If no residual fibrosis after debridement was found, a Bosworth augmentation was performed to strengthen the transfer. Functional assessment was performed using Kitaoka score. Postoperative complications were analyzed. Delay of work and sports recovery was noticed. Isokinetic evaluation was performed using Con-Trex. ®. dynamometer. Statistical analysis was performed using Student’s t-test and Wilcoxon test (level of significance, p < 0.05). Results: The mean follow-up was 61 months (range, 40–73). Functional outcome was excellent with a significant improvement of the average Kitaoka score at latest follow-up (98/100 (range, 90–100)). Average delay of work and sports recovery was 5 months (range, 2–12) and 10 months (range, 6–18) respectively. All patients returned to a sports activity within minor limitations. No re-rupture has been described. No major complication was observed particularly on wound healing. All patients presented with a loss of active range of motion of the hallux interphallangeal joint without subsequent hyperextension. However, no patient presented with functional weakness of the hallux during athletic or daily life activities. Isokinetic testing at 30 deg/sec and 120 deg/sec revealed a significant average decrease of 28±11% and 36±4.1% respectively, in the plantar flexion peak torque of the involved ankle compared with the non-involved ankle. Discussion: Although strength deficit persisted at latest follow-up, functional improvement was significant. Morbidity due to FHL harvesting was clinically in significant at latest follow-up. For patients with neglected or chronic Achilles tendon rupture with a rupture gap of at least 5 centimeters, surgical repair using FHL transfer with fibrous AT stumps reinforcement achieved excellent outcome at our latest follow-up

Recently, the field of tissue engineering has made numerous advances towards achieving artificial tendon substitutes with excellent mechanical and histological properties, and has had some promising experimental results. The purpose of this systematic review is to assess the efficacy of tissue engineering in the treatment of tendon injuries.

Abstract

Nerve transfer has become a common and often effective reconstructive strategy for proximal and complex peripheral nerve injuries of the upper limb. This case-based discussion explores the principles and potential benefits of nerve transfer surgery and offers in-depth discussion of several established and valuable techniques including: motor transfer for elbow flexion after musculocutaneous nerve injury, deltoid reanimation for axillary nerve palsy, intrinsic re-innervation following proximal ulnar nerve repair, and critical sensory recovery despite non-reconstructable median nerve lesions.

Stable fractures of the ankle can be safely treated non-operatively. It is also gradually being recognised that the integrity of the ‘medial column’ is essential for the stability of the fracture. It is generally thought that bi- and tri-malleolar fractures are unstable, as are pronation external rotation injuries resulting in an isolated high fibular fracture (Weber type-C), where the deltoid ligament is damaged or the medial malleolus fractured. However, how best to identify unstable, isolated, trans-syndesmotic Weber type-B supination external rotation (SER) fractures of the lateral malleolus remains controversial.

We provide a rationale as to how to classify SER distal fibular fractures using weight-bearing radiographs, and how this can help guide the management of these common injuries.

This study aimed to evaluate the histological and mechanical features of tendon healing in a rabbit model with second-harmonic-generation (SHG) imaging and tensile testing.

Lateral epicondylitis, or ’tennis elbow’, is a common condition that usually affects patients between 35 and 55 years of age. It is generally self-limiting, but in some patients it may continue to cause persistent symptoms, which can be refractory to treatment. This review discusses the mechanism of disease, symptoms and signs, investigations, current management protocols and potential new treatments.

A total of seven patients (six men and one woman) with a defect in the Achilles tendon and overlying soft tissue underwent reconstruction using either a composite radial forearm flap (n = 3) or an anterolateral thigh flap (n = 4). The Achilles tendons were reconstructed using chimeric palmaris longus (n = 2) or tensor fascia lata (n = 2) flaps or transfer of the flexor hallucis longus tendon (n = 3). Surgical parameters such as the rate of complications and the time between the initial repair and flap surgery were analysed. Function was measured objectively by recording the circumference of the calf, the isometric strength of the plantar flexors and the range of movement of the ankle. The Achilles tendon Total Rupture Score (ATRS) questionnaire was used as a patient-reported outcome measure. Most patients had undergone several previous operations to the Achilles tendon prior to flap surgery. The mean time to flap surgery was 14.3 months (2.1 to 40.7).

At a mean follow-up of 32.3 months (12.1 to 59.6) the circumference of the calf on the operated lower limb was reduced by a mean of 1.9 cm (sd 0.74) compared with the contralateral limb (p = 0.042). The mean strength of the plantar flexors on the operated lower limb was reduced to 88.9% of that of the contralateral limb (p = 0.043). There was no significant difference in the range of movement between the two sides (p = 0.317). The mean ATRS score was 72 points (sd 20.0). One patient who had an initial successful reconstruction developed a skin defect of the composite flap 12 months after free flap surgery and this resulted in recurrent infections, culminating in transtibial amputation 44 months after reconstruction.

These otherwise indicate that reconstruction of the Achilles tendon combined with flap cover results in a successful and functional reconstruction.

The Essex-Lopresti injury (ELI) of the forearm is a rare and serious condition which is often overlooked, leading to a poor outcome.

The purpose of this retrospective case study was to establish whether early surgery can give good medium-term results.

From a group of 295 patients with a fracture of the radial head, 12 patients were diagnosed with ELI on MRI which confirmed injury to the interosseous membrane (IOM) and ligament (IOL). They were treated by reduction and temporary Kirschner (K)-wire stabilisation of the distal radioulnar joint (DRUJ). In addition, eight patients had a radial head replacement, and two a radial head reconstruction.

All patients were examined clinically and radiologically 59 months (25 to 90) after surgery when the mean Mayo Modified Wrist Score (MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores (MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome.

In case of a high index of suspicion for ELI in patients with a radial head fracture, we recommend the following: confirmation of IOM and IOL injury with an early MRI scan; early surgery with reduction and temporary K-wire stabilisation of the DRUJ; preservation of the radial head if at all possible or replacement if not, and functional bracing in supination. This will increase the prospect of a good result, and avoid the complications of a missed diagnosis and the difficulties of late treatment.

We describe the routine imaging practices of Level 1 trauma centres for patients with severe pelvic ring fractures, and the interobserver reliability of the classification systems of these fractures using plain radiographs and three-dimensional (3D) CT reconstructions. Clinical and imaging data for 187 adult patients (139 men and 48 women, mean age 43 years (15 to 101)) with a severe pelvic ring fracture managed at two Level 1 trauma centres between July 2007 and June 2010 were extracted. Three experienced orthopaedic surgeons classified the plain radiographs and 3D CT reconstruction images of 100 patients using the Tile/AO and Young–Burgess systems. Reliability was compared using kappa statistics. A total of 115 patients (62%) had plain radiographs as well as two-dimensional (2D) CT and 3D CT reconstructions, 52 patients (28%) had plain films only, 12 (6.4%) had 2D and 3D CT reconstructions images only, and eight patients (4.3%) had no available images. The plain radiograph was limited to an anteroposterior pelvic view. Patients without imaging, or only plain films, were more severely injured. A total of 72 patients (39%) were imaged with a pelvic binder in situ.

Interobserver reliability for the Tile/AO (Kappa 0.10 to 0.17) and Young–Burgess (Kappa 0.09 to 0.21) was low, and insufficient for clinical and research purposes.

Severe pelvic ring fractures are difficult to classify due to their complexity, the increasing use of early treatment such as with pelvic binders, and the absence of imaging altogether in important patient sub-groups, such as those who die early of their injuries.

We report the clinical outcome and findings at second-look arthroscopy of 216 patients (mean age 25 years (11 to 58)) who underwent anterior cruciate ligament (ACL) reconstruction or augmentation. There were 73 single-bundle ACL augmentations (44 female, 29 male), 82 double-bundle ACL reconstructions (35 female, 47 male), and 61 single-bundle ACL reconstructions (34 female, 27 male).

In 94 of the 216 patients, proprioceptive function of the knee was evaluated before and 12 months after surgery using the threshold to detect passive motion test.

Second-look arthroscopy showed significantly better synovial coverage of the graft in the augmentation group (good: 60 (82%), fair: 10 (14%), poor: 3 (4%)) than in the other groups (p = 0.039). The mean side-to-side difference measured with a KT-2000 arthrometer was 0.4 mm (-3.3 to 2.9) in the augmentation group, 0.9 mm (-3.2 to 3.5) in the double-bundle group, and 1.3 mm (-2.7 to 3.9) in the single-bundle group: the result differed significantly between the augmentation and single-bundle groups (p = 0 .013). No significant difference in the Lysholm score or pivot-shift test was seen between the three groups (p = 0.09 and 0.65, respectively). In patients with good synovial coverage, three of the four measurements used revealed significant improvement in proprioceptive function (p = 0.177, 0.020, 0.034, and 0.026).

We conclude that ACL augmentation is a reasonable treatment option for patients with favourable ACL remnants.

Advances in hip arthroscopy have renewed interest in the ligamentum teres. Considered by many to be a developmental vestige, it is now recognised as a significant potential source of pain and mechanical symptoms arising from the hip joint. Despite improvements in imaging, arthroscopy remains the optimum method of diagnosing lesions of the ligamentum teres. Several biological or mechanical roles have been proposed for the ligament. Unless these are disproved, the use of surgical procedures that sacrifice the ligamentum teres, as in surgical dislocation of the hip, should be carefully considered. This paper provides an update on the development, structure and function of the ligamentum teres, and discusses associated clinical implications.

The June 2014 Wrist & Hand Roundup360 looks at: aart throwing not quite as we thought; two-gear, four-bar linkage in the wrist?; assessing outcomes in distal radial fractures; gold standard Swanson’s?; multistrand repairs of unclear benefit in flexor tendon release; for goodness’ sake, leave the thumb alone in scaphoid fractures; horizons in carpal tunnel surgery; treading the Essex-Lopresti tightrope; wrist replacement in trauma? and radial shortening reliable in the long term for Kienbock’s disease

A child with traumatic laceration of the tendo Achillis developed secondary infection after primary repair. This resulted in the loss of 5 cm of the distal part of the tendon and overlying soft tissue. The patient was treated with a free skin flap to cover the wound and to control the infection leaving reconstruction for a second-stage procedure.

However, when he was assessed two years after the skin-flap, delayed reconstruction proved to be unnecessary since he had regained normal ankle function spontaneously and could demonstrate equal function in both tendons.

We report an audit of 208 patients with a mean age of 39 years (16 to 65) attending the Orthopaedic Assessment Unit at the Wellington Hospital between January 2006 and December 2007 with an injury of the tendo Achillis requiring immobilisation in a cast. Information on assessment of venous thromboembolism (VTE) risk, prophylactic measures and VTE events for all patients was obtained from the medical records. A VTE risk factor was documented in the records of three (1%) patients. One of the 208 patients received aspirin prophylaxis; none received low molecular weight heparin. In all, 13 patients (6.3%, 95% confidence interval 3.4 to 10.5) developed symptomatic VTE during immobilisation in a cast, including six with a distal deep-vein thrombosis (DVT), four with a proximal DVT, and three with a confirmed pulmonary embolus. This incidence of symptomatic VTE is similar to that reported following elective hip replacement.

We propose that consideration is given to VTE prophylaxis during prolonged immobilisation of the lower limbs in a cast, to ensure that the same level of protection is provided as for patients undergoing elective hip replacement.

We investigated the predictive value of intra-operative neurophysiological investigations in obstetric brachial plexus injuries. Between January 2005 and June 2011 a total of 32 infants of 206 referred to our unit underwent exploration of the plexus, including neurolysis. The findings from intra-operative electromyography, sensory evoked potentials across the lesion and gross muscular response to stimulation were evaluated. A total of 22 infants underwent neurolysis alone and ten had microsurgical reconstruction. Of the former, one was lost to follow-up, one had glenoplasty and three had subsequent nerve reconstructions. Of the remaining 17 infants with neurolysis, 13 (76%) achieved a modified Mallet score > 13 at a mean age of 3.5 years (0.75 to 6.25). Subluxation or dislocation of the shoulder is a major confounding factor. The positive predictive value and sensitivity of the intra-operative EMG for C5 were 100% and 85.7%, respectively, in infants without concurrent shoulder pathology. The positive and negative predictive values, sensitivity and specificity of the three investigations combined were 77%, 100%, 100% and 57%, respectively.

In all, 20 infants underwent neurolysis alone for C6 and three had reconstruction. All of the former and one of the latter achieved biceps function of Raimondi grade 5. The positive and negative predictive values, sensitivity and specificity of electromyography for C6 were 65%, 71%, 87% and 42%, respectively.

Our method is effective in evaluating the prognosis of C5 lesion. Neurolysis is preferred for C6 lesions.

Injury to the perforating branch of the peroneal artery has not been reported previously as a cause of acute compartment syndrome following soft-tissue injury to the ankle. We describe the case of a 23-year-old male who sustained such an injury resulting in an acute compartment syndrome. In a review of the literature, we could find only five previous cases, all of which gave rise to a false aneurysm which was detected after the acute event.

The role of arthroscopy in the treatment of soft-tissue injuries associated with proximal tibial fractures remains debatable. Our hypothesis was that MRI over-diagnoses clinically relevant associated soft-tissue injuries. This prospective study involved 50 consecutive patients who underwent surgical treatment for a split-depression fracture of the lateral tibial condyle (AO/OTA type B3.1). The mean age of patients was 50 years (23 to 86) and 27 (54%) were female. All patients had MRI and arthroscopy. Arthroscopy identified 12 tears of the lateral meniscus, including eight bucket-handle tears that were sutured and four that were resected, as well as six tears of the medial meniscus, of which five were resected. Lateral meniscal injuries were diagnosed on MRI in four of 12 patients, yielding an overall sensitivity of 33% (95% confidence interval (CI) 11 to 65). Specificity was 76% (95% CI 59 to 88), with nine tears diagnosed among 38 menisci that did not contain a tear. MRI identified medial meniscal injuries in four of six patients, yielding an overall sensitivity of 67% (95% CI 24 to 94). Specificity was 66% (95% CI 50 to 79), with 15 tears diagnosed in 44 menisci that did not contain tears.

MRI appears to offer only a marginal benefit as the specificity and sensitivity for diagnosing meniscal injuries are poor in patients with a fracture. There were fewer arthroscopically-confirmed associated lesions than reported previously in MRI studies.

The purpose of this study was to assess the clinical and radiological outcomes of dorsal intercarpal ligament capsulodesis for the treatment of static scapholunate instability at a minimum follow-up of four years. A total of 59 patients who underwent capsulodesis for this condition were included in a retrospective analysis after a mean of 8.25 years (4.3 to 12). A total of eight patients underwent a salvage procedure at a mean of 2.33 years (0.67 to 7.6) and were excluded. The mean range of extension/flexion was 88° (15° to 135°) and of ulnar/radial deviation was 38° (0° to 75°) at final follow-up. The mean Disabilities of the Arm Shoulder and Hand (DASH) score and Mayo wrist scores were 28 (0 to 85) and 61 (0 to 90), respectively. After significant improvement immediately post-operatively (p < 0.001 and p = 0.001, respectively), the mean scapholunate and radiolunate angles deteriorated to 70° (40° to 90°) and 8° (-15° to 25°), respectively, at final follow-up, which were not significantly different from their pre-operative values (p = 0.6 and p = 0.4, respectively). The mean carpal height index decreased significantly from 1.53 (1.38 to 1.65) to 1.48 (1.29 to 1.65) indicating progressive carpal collapse (p < 0.001); 40 patients (78%) had radiological evidence of degenerative arthritis.

Capsulodesis did not maintain carpal reduction over time. Although the consequent ongoing scapholunate instability resulted in early arthritic degeneration, most patients had acceptable long-term function of the wrist.

Between May 1998 and May 2007 we carried out 50 Avon patellofemoral joint replacements in 32 patients with isolated patellofemoral osteoarthritis.

There were no revisions in the first five years, giving a cumulative survival of 100% for those with a minimum follow-up of five years. The mean follow-up was 5.3 years (2.1 to 10.2). The median Oxford knee score was 30.5 (interquartile range 22.25 to 42.25). In patients with bilateral replacements the median Euroqol General health score was 50 which was significantly lower than that of 75 in those with a unilateral replacement (p = 0.047). The main complication was progression of disease, which was identified radiologically in 11 knees (22%). This highlights the need for accurate selection of patients. Our findings suggest that the Avon prosthesis survives well and gives a satisfactory functional outcome in the medium term.

We retrospectively studied the possibility that direct trauma to the biceps muscle might be the cause of poor elbow flexion and supination in 18 consecutive children with birth lesions of the brachial plexus who had delayed or impaired biceps recovery despite neurophysiological evidence of reinnervation. All had good shoulder and hand function at three months of age. Eight recovered a strong biceps after six months, but nine required a pectoralis minor to biceps transfer to augment elbow flexion and supination. One had a delayed but good recovery of the biceps after microsurgical reconstruction of the plexus. All had a clinical ‘pseudotumour’ in the biceps muscle, which was biopsied during pectoralis minor transfer in two patients and showed rupture and degeneration of muscle fibres with a fibro-fatty infiltrate, suggesting previous muscle trauma.

Direct muscle trauma is an uncommon but important cause of delayed or impaired biceps recovery after brachial plexus birth injuries. Surgery to reinnervate the biceps muscle will not work if substantial muscle damage is present when a suitable muscle transfer should be considered.

Fractures of the proximal humerus can lead to malalignment of the humeral head, necrosis and post-traumatic osteoarthritis. In such cases surface replacement might be a promising option.

A total of 28 shoulders with glenohumeral arthritis subsequent to a fracture underwent surface replacement arthroplasty of the humeral head in patients with a mean age of 60 years (35 to 83). On the basis of the inclination of the impacted head, post-traumatic arthritis was divided into three types: type 1, an impacted fracture of the head in an anatomical position (seven cases); type 2, a valgus impacted fracture (13 cases); type 3, a varus impacted fracture (eight cases). The outcome was measured by means of the Constant score.

According to the Boileau classification of the sequelae of fractures of the proximal humerus, all 28 patients had a final result of intra-capsular category 1. The mean Constant score for the 28 shoulders increased from 23.2 points (2 to 45) pre-operatively to 55.1 points (20 to 89) at a mean of 31 months (24 to 66) post-operatively. Valgus impacted fractures had significantly better results (p < 0.039).

Surface replacement arthroplasty can provide good results for patients with post-traumatic osteoarthritis of the shoulder. Their use avoids post-operative complications of the humeral shaft, such as peri-prosthetic fractures. Further surgery can be undertaken more easily as the bone stock is preserved.

The aim of this study was to investigate the occurrence of tissue hypoxia and apoptosis at different stages of tendinopathy and tears of the rotator cuff.

We studied tissue from 24 patients with eight graded stages of either impingement (mild, moderate and severe) or tears of the rotator cuff (partial, small, medium, large and massive) and three controls. Biopsies were analysed using three immunohistochemical techniques, namely antibodies against HIF-1α (a transcription factor produced in a hypoxic environment), BNip3 (a HIF-1α regulated pro-apoptotic protein) and TUNEL (detecting DNA fragmentation in apoptosis).

The HIF-1α expression was greatest in mild impingement and in partial, small, medium and large tears. BNip3 expression increased significantly in partial, small, medium and large tears but was reduced in massive tears. Apoptosis was increased in small, medium, large and massive tears but not in partial tears.

These findings reveal evidence of hypoxic damage throughout the spectrum of pathology of the rotator cuff which may contribute to loss of cells by apoptosis. This provides a novel insight into the causes of degeneration of the rotator cuff and highlights possible options for treatment.

We reviewed 42 consecutive children with a supination deformity of the forearm complicating severe birth lesions of the brachial plexus.

The overall incidence over the study period was 6.9% (48 of 696). It was absent in those in Narakas group I (27.6) and occurred in 5.7% of group II (13 of 229), 9.6% of group III (11 of 114) and 23.4% of group IV (18 of 77).

Concurrent deformities at the shoulder, elbow, wrist and hand were always present because of muscular imbalance from poor recovery of C5 and C7, inconsistent recovery of C8 and T1 and good recovery of C6. Early surgical correction improved the function of the upper limb and hand, but there was a tendency to recurrence. Pronation osteotomy placed the hand in a functional position, and increased the arc of rotation of the forearm. The supination deformity recurred in 40% (17 of 42) of those treated by pronation osteotomy alone, probably because of remodelling of the growing bone.

Children should be followed up until skeletal maturity, and the parents counselled on the likelihood of multiple operations.

The use of volar locking compression plates for the treatment of fractures of the distal radius is becoming increasingly popular because of the stable biomechanical construct, less soft-tissue disturbance and early mobilisation of the wrist. A few studies have reported complications such as rupture of flexor tendons. We describe three cases of rupture of extensor tendons after the use of volar locking compression plates. We recommend extreme care when drilling and placing the distal radial screws to prevent damaging the extensor tendons.

In a prospective randomised study we compared the results of arthroscopic subacromial bursectomy alone with debridement of the subacromial bursa followed by acromioplasty. A total of 57 patients with a mean age of 47 years (31 to 60) suffering from primary subacromial impingement without a rupture of the rotator cuff who had failed previous conservative treatment were entered into the trial. The type of acromion was classified according to Bigliani. Patients were assessed at follow-up using the Constant score, the simple shoulder test and visual analogue scores for pain and functional impairment. One patient was lost to follow-up.

At a mean follow-up of 2.5 years (1 to 5) both bursectomy and acromioplasty gave good clinical results. No statistically significant differences were found between the two treatments. The type of acromion and severity of symptoms had a greater influence on the clinical outcome than the type of treatment. As a result, we believe that primary subacromial impingement syndrome is largely an intrinsic degenerative condition rather than an extrinsic mechanical disorder.

Whereas a general trend in the management of obstetric brachial plexus injuries has been nerve reconstruction in patients without spontaneous recovery of biceps function by three to six months of age, many recent studies suggest this may be unnecessary. In this study, the severity of glenohumeral dysplasia and shoulder function and strength in two groups of matched patients with a C5-6 lesion at a mean age of seven years (2.7 to 13.3) were investigated. One group (23 patients) underwent nerve reconstruction and secondary operations, and the other (52 patients) underwent only secondary operations for similar initial clinical presentations. In the patients with nerve reconstruction shoulder function did not improve and they developed more severe shoulder deformities (posterior subluxation, glenoid version and scapular elevation) and required a mean of 2.4 times as many operations as patients without nerve reconstruction.

This study suggests that less invasive management, addressing the muscle and bone complications, is a more effective approach. Nerve reconstruction should be reserved for those less common cases where the C5 and C6 nerve roots will not recover.
