The influence of fatty infiltration and muscle atrophy of the rotator cuff muscles on midterm functional outcomes in total shoulder resurfacing at six years' follow-up.

Background: We report functional outcomes at six years in patients with varying degrees of fatty infiltration and atrophy of the rotator cuff muscles who have undergone anatomic total shoulder replacement.

Methods: A retrospective analysis of case notes and magnetic resonance imaging scans of patients undergoing total shoulder replacement for primary glenohumeral arthritis was performed. Patients were grouped based upon their pre-operative magnetic resonance imaging findings for fatty infiltration, muscle area and tendinopathy.

Recurrent Fusobacterium pyogenic myositis of the rotator cuff A case report of recurrent Fusobacterium pyogenic myositis of the rotator cuff.

Pyogenic myositis is uncommon. It normally affects the large muscle groups in the lower limb or trunk and the most common causative organism is Staphylococcus aureus. We present a case of an immunocompetent man who, unusually, had a recurring form of the disease in subscapularis and teres minor.

The effect of ultrasound guided steroid injection on progression to surgery in thumb CMC arthritis.

Thumb carpometacarpal joint (CMCJ) osteoarthritis is a common complaint that produces pain and disability within the hand. This study aims to ascertain whether joint injection with local anaesthetic and steroid is of predicative value in disease progression in thumb carpometacarpal osteoarthritis. Forty-three patients were assessed at an average follow up of 24 months following ultrasound-guided injection.

The correct rotation of the femoral component in patellofemoral replacement: a laboratory assessment of a surgical technique.

Ensuring correct rotation of the femoral component is a challenging aspect of patellofemoral replacement surgery. Rotation equal to the epicondylar axis or marginally more external rotation is acceptable. Internal rotation is associated with poor outcomes.

Shoulder arthroplasty. Part 2: normal and abnormal radiographic findings.

Frequently, the decision made by general practitioners or musculoskeletal triage assessment services to refer patients for specialist review is initiated by a radiological report. Following shoulder arthroplasty it is important to ensure that any patient with asymptomatic evidence of a failing prosthesis is referred for review so that revision surgery can be contemplated and planned before the situation becomes unsalvageable. The first paper in this series described the various types of shoulder arthroplasty and indications for each.
