Background: Rotator cuff tears are one of the most common causes of shoulder pain. All-suture anchors are increasingly being used in the arthroscopic repair of rotator cuff tears. The purpose of this experimental study is to evaluate the biomechanical properties of all-suture anchors at different insertion sites in the proximal humerus relevant to rotator cuff repairs and the remplissage procedure. Methods: Sixteen cadaveric shoulders were used for the study. Four all-suture anchors were inserted in each proximal humerus at common anchor insertion sites on the rotator cuff footprint and a simulated Hill-Sachs defect...

Adam C Watson, Richard P Jamieson, Andrew C Mattin, Richard S Page
Background: We aimed to assess the validity of magnetic resonance imaging (MRI) in assessing the subcorocoid space and determine the validity of novel sagittal plane subcorocoid space measurements. Methods: We assessed 33 arthroscopically proven subscapularis tears with MRIs compared to 33 (instability) controls with normal subscapularis tendons. Three examiners analyzed MRIs for seven static indices of corocoid morphology, in axial and sagittal planes. We explored reviewer variation using intraclass correlation coefficients (ICC) and differences between the two groups was explored using t -tests...

Kuen Chin, Alex Chowdhury, Dimitra Leivadiotou, Helen Marmery, Philip Michael Ahrens
Background: A number of radiographic signs have been previously demonstrated to be associated with degenerative rotator cuff tears. An ability to predict the presence of a tear by radiography would permit the early commencement of appropriate treatment and the avoidance of unnecessary invasive investigations. The aim of the present study was to determine the accuracy of using radiographic signs to predict the presence of a cuff tear on arthroscopy. Methods: Fifty consecutive patients who had undergone shoulder arthroscopy and had pre-operative plain radiographs were included...

REVIEW
Alessandro Castagna, Raffaele Garofalo
Anatomic total shoulder arthroplasty (TSR) has been shown to generate good to excellent results for patients with osteoarthritis and a functioning rotator cuff. Many studies have reported that the glenoid component loosening and failure remain the most common long-term complication of total shoulder arthroplasty. The approach to glenoid component is critical because a surgeon should consider patient-specific anatomy, preserving bone stock and joint line restoration, for a good and durable shoulder function...

We report the case of a middle-age lady who presented following minor trauma, with dominant-sided anterior elbow pain and swelling of 6 months in duration. She was assessed clinically, and underwent investigations, which confirmed features consistent with giant cell tumour (GCT) of distal biceps tendon sheath. She underwent uneventful en-bloc excisional surgery. She did not have radiotherapy. She is now 5 years postoperatively asymptomatic, with full function, and with no signs of recurrence.

We report a case of 30-year-old lady presenting with a suprascapular nerve (SSN) injury in the postpartum period. Two days following normal delivery, the patient experienced progressive weakness in her left shoulder, of spontaneous onset. Initially thought to be a rotator cuff tear, further imaging indicated a lesion in the SSN. Isolated SSN palsy is a rare occurrence. Previously reported cases of brachial plexus nerve injuries are due to trauma, traction, iatrogenic and the positioning of the patient during surgery...

Rupture of the pectoralis major remains an infrequent injury, although, recently, it has been reported more commonly as a result of the expansion and increasing popularity of competitive sports, as well as developments in sports medicine. A number of surgical repair techniques have been described for direct repair in the acute setting. However, on occasion, the pectoralis major muscle is so retracted that a tension-free direct repair is not possible. We describe a technique for allograft reconstruction of the pectoralis major, with our preliminary outcomes, where it is found or anticipated that a direct repair is not possible...
