Background: Symptoms of fatigue and pain are often reported for the trapezius muscle in the shoulder. The present study evaluated endurance in the trapezius muscles of healthy participants using electric twitch mechanomyography (ETM). Methods: Surface electrodes and a tri-axial accelerometer were placed over the left trapezius muscle. Muscles were stimulated for 3 min each at 2 Hz, 4 Hz and 6 Hz. Maintenance of acceleration during muscle twitches was used to calculate an endurance index (EI)...

We describe an unusual case of ulnar nerve compression (cubital tunnel syndrome) caused by synovial protrusion in primary synovial chondromatosis of the elbow in a 59-year-old man. Magnetic resonance imaging is a useful tool for diagnosing this rare condition. Surgical excision of the intra-articular multiple loose bodies and ulnar nerve decompression were performed. The clinician should be aware of primary synovial chondromatosis as one of the causative factors of cubital tunnel syndrome.

Background: Radiographs are part of routine clinical care after radial head arthroplasty (RHA). Therefore, the aim of this diagnostic study was to assess the interobserver reliability of radiographic assessment following RHA. Methods: Anteroposterior (AP) and lateral radiographs of 24 consecutive patients who underwent press-fit bipolar RHA were evaluated with respect to 14 parameters by 14 orthopaedic surgeons specializing in the elbow: shaft loosening (AP, lateral), subcollar bone resorption, nonbridging heterotopic ossification, capitellar erosion, capitellar osteopenia, implant size, ulnohumeral joint gapping, ulnohumeral joint degeneration, proximal radio-ulnar joint congruency, stem size, stem positioning (AP, lateral) and component dissociation or polyethylene wear of the head with increased angulation...

Background: The rate of retear after rotator cuff surgery is 17%. Magnetic resonance imaging (MRI) scans are used for confirmative diagnosis of retear. However, because of the presence of titanium suture anchors, metal artefacts on the MRI are common. The present study evaluated the diagnostic value of MRI after rotator cuff tendon surgery with respect to assessing the integrity as well as the degeneration and atrophy of the rotator cuff tendons when titanium anchors are in place. Methods: Twenty patients who underwent revision surgery of the rotator cuff as a result of a clinically suspected retear between 2013 and 2015 were included...

Background: The effectiveness of the Latarjet largely depends on accurate graft placement, as well as on proper position and direction of the screws. We present our technique for an arthroscopically-assisted Latarjet comparing radiological results with the open technique. Methods: We retrospectively reviewed the postoperative computed tomography scans of 38 patients who underwent a Latarjet procedure. For 16 patients, the procedure was performed with the open technique and, for 22 patients, it was performed using an arthroscopically-assisted technique...

Background: Hydrodilatation (HD) has been shown to improve pain and function in patients with adhesive capsulitis (AC). There is no consensus concerning how HD should be performed or what volume should be injected. It has distinct advantages compared to surgery; however, it is a painful procedure and is often poorly tolerated. Methods: We retrospectively reviewed all patients referred for HD over a 2.5-year period aiming to assess whether volume injected influences outcome...

Background: Shoulder resurfacings represent approximately one-third of shoulder arthroplasties and have the highest revision rates of any shoulder arthroplasty. We present a survival analysis of the Global CAP hemi-resurfacing implanted by multiple surgeons with up to 10 years of follow-up. Methods: A life-table survival analysis of the Global CAP hemi-resurfacing was undertaken in a single site with multiple surgeons. Two survival analyses were performed; first, where failure was defined as component exchange and, second, where failure was defined as re-operation for any reason...

Michael Adrian Stewart
A central aim of modern day healthcare is to deliver a high quality, patient-centred service that addresses the expectations of its service users. However, mounting research evidence highlights a lack of patient satisfaction across a range of healthcare settings, with an overwhelming proportion of complaints relating to interprofessional communication. The link between interprofessional miscommunication and poor patient outcomes has been well documented. All too often, patients are left feeling stuck in the middle between opposing opinions, differing diagnoses and conflicting clinical outlooks...

Cezary Kocialkowski, Rebecca Carter, Chris Peach
Triceps tendon ruptures are rare injuries and are frequently missed on initial presentation to the emergency department. In cases of complete rupture, surgical repair is recommended but no guidelines exist on the optimum reconstructive technique or rehabilitation. We present a surgical technique and rehabilitation programme for the management of these injuries. A midline posterior incision is performed, the ruptured triceps tendon is identified and mobilized, and the tendon footprint is prepared. The tendon is then repaired using bone suture anchors, with a parachute technique, and held in 40° of flexion...

Julie Bury, Chris Littlewood
Background: Shoulder pain is a common musculoskeletal presentation, with disorders of the rotator cuff (RC) regarded as the most frequent cause. Conservative treatment is often the initial management; however, findings from a previous survey showed considerable variations in clinical practice, including the use of modalities that are not supported in the literature, suggesting that research is not impacting on practice. The present study aimed to survey current UK physiotherapy practice for the management of RC disorders and to determine whether this has changed over the 5-year period since the last survey was conducted...

Background: Optimal surgical treatment of lateral epicondylitis remains uncertain. Recently, radiofrequency microtenotomy (RFMT) has been proposed as a suitable treatment. We compared RFMT with standard open release (OR) in this prospective randomized controlled trial. Methods: In total, 41 patients with symptoms for at least 6 months were randomized into two groups: 23 patients had RFMT and 18 had OR. Two patients from RFMT withdrew. Each patient underwent Numerical Rating Scale (NRS) pain score, grip strength and Disabilities of the Arm, Shoulder and Hand (DASH) scores pre-operatively and at 6 weeks...

Background: The present study aimed to determine anatomic references for the placement of five proximal humerus locking plates. Methods: Five proximal humerus locking-plate systems were placed on six human shoulder cadavers. Plates were positioned by fluoroscopic confirmation so that the inferior oblique screw was within 5 mm of the inferomedial cortex. Plate position was measured using the superior border of the pectoralis major tendon (PMT) to the bottom of the first slotted or nonlocking hole and top of the plate to the top of the greater tuberosity...

Background: Bone-grafting procedures for recurrent shoulder instability produce low recurrence rates, although they are associated with complications such as graft non-union. Inadequate screw purchase is considered to play a causative role. However, excessive screw length can endanger neurovascular structures. The present study aimed to investigate how type and length of screws influences construct rigidity in a simplified glenoid model. Methods: Testing was performed on composite polyurethane foam models with material properties and abstract dimensions of a deficient glenoid and an bone graft...

REVIEW
Peter Domos, Enricomaria Lunini, Gilles Walch
The Latarjet procedure is a well-known, safe and reliable technique to treat primary or recurrent anterior dislocations or subluxations, with or without hyperlaxity, with or without glenoid bone loss. Both the open and the arthroscopic methods produce excellent clinical results, with a low rate of recurrent instability. There have been concerns of a higher surgical complication rate associated with this procedure, however, large reviews reported an overall complication rate in the open Latarjet procedure of 15%...

REVIEW
Salma Chaudhury, Luckshman Bavan, Neal Rupani, Kyriacos Mouyis, Ro Kulkarni, Amar Rangan, Jonathan Rees
Background: Shoulder pain secondary to acromioclavicular joint pain is a common presentation in primary and secondary care but is often poorly managed as a result of uncertainty about optimal treatment strategies. Osteoarthritis is the commonest cause. Although acromioclavicular pain can be treated non-operatively and operatively, there appears to be no consensus on the best practice pathway of care for these patients, with variations in treatment being common place. The present study comprises a scoping review of the current published evidence for the management of isolated acromioclavicular pain (excluding acromioclavicular joint dislocation)...
