Recurrent shoulder instability and resultant glenoid and humeral head bone loss are not infrequently encountered in the population today, specifically in young, athletic patients. This review on the management of bone loss in recurrent glenohumeral instability discusses the relevant shoulder anatomy that provides stability to the shoulder joint, relevant history and physical examination finding...

Recurrent anterior shoulder instability may result from a spectrum of overlapping, often coexistent factors, one of which is glenoid bone loss. Untreated, glenoid bone loss may lead to recurrent instability and poor patient satisfaction. Recent studies suggest that the glenoid rim is altered in up to 90% of shoulders with recurrent instability, thus underscoring the need for careful diagnosis, ...

BACKGROUND Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. METHODS With a numerical musculoskeletal shoulder model, we analysed and compared three values of thickness of a typical all-polyethylene glenoid compo...

We present a case of concurrent rotator cuff tear and axillary nerve palsy resulting from anterior dislocation of the shoulder and a large glenoid rim fracture-a "terrible tetrad." A 61-year-old woman fell on her right shoulder. Radiographs showed anterior dislocation of the shoulder with a glenoid rim fracture, and an MRI two months after injury revealed a rotator cuff tear. Upon referral to o...

Shoulder arthroplasty is a demanding procedure with a known complication rate. Most complications are associated with the glenoid component, a fact that has stimulated investigation into that specific component of the implant. Avoiding glenoid component malposition is very important and is a key reason for recent developments in pre-operative planning and instrumentation to minimise risk.Patien...

Surgery is usually recommended for displaced glenoid fractures, with open reduction and internal fixation as the standard operative treatment. Three approaches have been recommended in the reduction of glenoid fractures: Anterior, posterior and combined; however, a traditional approach may be difficult due to a high position or a comminuted Ideberg type III fracture. The combined approach resul...

BACKGROUND Progress in developing effective surgical techniques, such as scapular allograft reconstruction, enhance shoulder stability and extremity function, in patients following scapular tumor resection. METHODS Case details from seven patients who underwent scapular allograft reconstruction following scapular tumor resection were reviewed. A wide marginal resection (partial scapulectomy) ...

BACKGROUND Hemiarthroplasty continues to be a common surgical treatment for glenohumeral arthritis. Unfortunately, some patients will develop painful glenoid arthrosis necessitating revision to total shoulder arthroplasty. Previously reported results of revision have demonstrated variability in results and difficulty. The purpose of this study was to determine the difficulty and results of revi...

Clinicians have had much experience with uncemented humeral components. A press-fitted humeral component will usually remain stable in the absence of a glenoid component. From the information available, surgeons should not continue to use press-fitted humeral components for total shoulder arthroplasty. Tissue ingrowth humeral components offer promise; however, the reports to date have short or ...
