Management of distal biceps tendon ruptures: a survey of fellowship-trained subspecialist elbow surgeons.

BACKGROUND: There are several approaches to the management of distal biceps tendon ruptures, with no consensus on what constitutes best practice. METHODS: An online survey queried the perceptions and management of distal biceps tendon ruptures amongst fellowship-trained subspecialty elbow surgeons, which primarily comprised of members of the Shoulder and Elbow Society of Australia, the national subspecialist interest group of the Australian Orthopaedic Association and the Mayo Clinic Elbow Club (Rochester, MN, USA). RESULTS: One hundred surgeons responded. The median (IQR) experience as orthopedic surgeons amongst respondents was 17 (10-23) years; 78% of respondents saw >10 cases of distal biceps tendon ruptures annually; 95% of respondents would recommend surgery for symptomatic radiologically-confirmed partial tears, the most common indications being pain (83%), weakness (60%), and tear size (48%). Forty-three percent of respondents would have grafts available for tears older than 6 weeks. The one-incision approach (70%) was preferred over two incisions (30%); 78% of one-incision users believed that their repair location was anatomic, compared to 100% of two-incision users. One-incision users were more likely to have encountered lateral antebrachial cutaneous nerve (78% vs. 46%) and superficial radial nerve palsies (28% vs. 11%). Two-incision users were more likely to have encountered posterior interosseus nerve palsy (21% vs. 15%), heterotopic ossification (54% vs. 42%), and synostosis (14% vs. 0%). Re-ruptures were the most common cause of reoperation. The more conservative a respondent's postoperative immobilization was, the less likely they were to have ever encountered re-rupture (14% amongst cast users, 29% amongst splint/brace users, 49% amongst sling users, 100% amongst non-immobilizers). Thirty percent of respondents who placed elbow strength restrictions for 6 months postoperatively encountered re-rupture, compared to 40% amongst those who restricted for 6-12 weeks postoperatively. CONCLUSIONS: The operation rate for repair of distal biceps tendon ruptures amongst subspecialist elbow surgeons is high, as seen in our cohort. However, there is a large variation in the approach toward its management. One incision (anterior) was preferred over two incisions (anterior and posterior). Complications from repair of distal biceps tendon ruptures can be expected even amongst subspecialists, and are associated with surgical approach. The responses imply that more conservative postoperative rehabilitation may be associated with a lower risk of re-rupture.

Traumatic irreducible anterior dislocation of the radio-capitellar joint due to entrapment of the brachialis tendon lateral to the radial head: A case report.

Elbow dislocation is the second most common type of joint dislocation in adults and the most common joint dislocation in children. These dislocations are commonly associated with significant soft tissue injury and/or fractures. Anterior dislocation of the radio-capitellar articulation is uncommon. Failure of relocation of the radial head due to soft tissue imposition requiring open reduction is rare, however, is extremely important to recognise clinically and radiologically. This case report describes a case of anterior dislocation of the radio-capitellar joint due to entrapment of the brachialis tendon lateral to the radial head and discusses the radiological assessment and the spectrum of causes of a clinically irreducible radio-capitellar joint. Misdiagnosis of a dislocation or failed reduction may result in long-term functional sequelae for the patient.

Isolated versus combined medial patellofemoral ligament reconstruction for lateral instability of the patella.

INTRODUCTION: Medial patellofemoral ligament reconstruction (MPFLR) is regularly combined with a tibial tuberosity transfer (TTT) in cases of recurrent patellar instability with underlying structural deformity. However, these indications for a TTT have recently come into question. This study aimed to assess the traditional indications by comparing the outcomes of isolated and combined MPFLR for the treatment of recurrent lateral patellar dislocation. METHODS: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies were those which reported the outcomes of either isolated or combined or both MPFLR. Studies were required to report at least one of the following: redislocation rate, revision due to instability, or the Kujala score. RESULTS: We found no difference between isolated and combined MPFLR in terms of redislocation ( p = 0.48), revisions due to instability ( p = 0.36), positive apprehension tests ( p = 0.25), or the Kujala score ( p = 0.58). Combined reconstruction presented more complications compared to isolated procedures ( p = 0.05). Subgroup analysis revealed no significant difference between studies investigating isolated medial patellofemoral ligament reconstruction MPFLR performed in patients with normal tibial tuberosity-trochlear groove (TT-TG) distances only or in patients with both normal and elevated TT-TG distances. CONCLUSIONS: According to the published data, there is no difference in outcomes between isolated and combined MPFLR. Underlying structural deformity did not demonstrate any significant effect on the success of the isolated MPFLR. Although there are definite indications for combined reconstruction, the current evidence suggests that our inclusion criteria may not be entirely correct. Further study is required to clarify and refine the true indications for combined MPFLR. LEVEL OF EVIDENCE: III, meta-analysis of nonrandomized studies.

Reverse Shoulder Arthroplasty for the treatment of Proximal humeral fractures in the Elderly (ReShAPE trial) : study protocol for a multicentre combined randomised controlled and observational trial.

BACKGROUND: Proximal humeral fractures are common in older patients. The majority are minimally displaced and are associated with good outcomes after nonoperative treatment. Poorer outcomes are associated with displaced, multipart fractures. There is no clear benefit from surgical fracture fixation compared to nonoperative treatment. Replacement of the fractured humeral head with a hemiarthroplasty is another treatment option, but has not been shown to be clearly superior to nonoperative treatment or internal fixation. Recently, reverse total shoulder arthroplasty has been used to treat these fractures, particularly in the older population with several case series demonstrating good outcomes. No comparative trial has been performed to test the effectiveness of reverse total shoulder arthroplasty against nonoperative treatment. METHODS/DESIGN: ReShAPE (Reverse Shoulder Arthroplasty for the treatment of Proximal humeral fractures in the Elderly) is a multicenter combined randomized and observational study. The primary objective is to compare pain and function 12 months post fracture using the American Shoulder and Elbow Society (ASES) score in patients aged 70 years or older with three- and four-part proximal humeral fractures treated by either reverse shoulder arthroplasty or nonoperative treatment. Secondary outcome measures will include the DASH (Disability of the Arm, Shoulder and Hand) score, the EQ-5D (EuroQol Health Survey), the EQ-VAS, pain, radiological parameters and complications. DISCUSSION: The study will assess the effectiveness of reverse shoulder arthroplasty for complex proximal humeral fractures and thereby guide treatment of a common injury in the older population.

Bilateral Primary Repair of Simultaneous Bilateral Distal Biceps Rupture.

A case of simultaneous bilateral distal biceps tendon rupture in a recreational gymnast is presented. Achieving bilateral acute primary repair can be challenging as any immobilization will lead to disability and difficulty with self-care and activities of daily living. We have reviewed the evidence of this rare condition and demonstrate that modern rehabilitation techniques, which allow early mobilization, can make simultaneous bilateral primary repair a viable option in such cases.

Subcapital fracture of the femoral neck in medically unwell patients: technique for fixation using direct infiltration local anaesthetic rather than regional blockade.

INTRODUCTION: Patients presenting with fracture of the femoral neck are usually elderly, and often have extensive co-morbidity. Patients who are considered able to survive an operation under general or regional anaesthesia usually undergo surgical stabilisation of the fracture or hemiarthroplasty of the hip for pain relief, to facilitate mobilisation and minimise the risk of developing the sequelae of bed rest. Patients who are considered too unwell for surgery are often treated non-operatively. These patients have a high morbidity and mortality and present significant nursing difficulties. STUDY: We describe a technique for fixation of subcapital fracture of the femoral neck under local anaesthesia direct infiltration only which is suitable for the medically unwell patient who may otherwise be treated non-operatively. A case series of patients on whom it was performed is presented. RESULTS: None of the patients required a supplementary anaesthetic technique, all survived to discharge from hospital. CONCLUSION: We recommend all patients with a subcapital fracture of the femoral neck are offered surgery to optimise their chance of survival and avoid the morbidity associated with bed rest.
