BACKGROUND AND PURPOSE Humeral resurfacing has shown promising results for osteoarthritis, but revisions for glenoid erosion have been reported frequently. We investigated the hypothesis that preoperative glenoid wear and postoperative progress of glenoid erosion would influence the clinical outcome. METHODS We reviewed 61 resurfacing hemiarthroplasties (55 patients) for primary osteoarthriti...

BACKGROUND AND PURPOSE In detection of glenoid labrum pathology, MR arthrography (MRA) has shown sensitivities of 88-100% and specificities of 89-93%. However, our practice suggested that there may be a higher frequency of falsely negative reports. We assessed the accuracy of this costly modality in practice. PATIENTS AND METHODS We retrospectively reviewed MRA reports of 90 consecutive patie...

A 52-year-old man with no significant medical history presented to the emergency department (ED) after a mechanical fall onto his nondominant left hand. Physical examination was suggestive of a glenohumeral dislocation, and radiographs confirmed a subcoracoid anterior glenohumeral dislocation (Figure 1). The patient was neurovascularly intact, but complained of severe pain and refused initial a...

PURPOSE The purpose of this study is to investigate and analyze accompanying lesions including injury types of anteroinferior labrum lesion in young and active patients who suffered traumatic anterior shoulder dislocation for the first time. MATERIALS AND METHODS The study used magnetic resonance angiography (MRA) to 40 patients with acute anterior shoulder dislocation from April 2004 to Apri...

Despite improvements in glenoid prosthesis design, materials and surgical techniques, complications related to the glenoid component continue to be a leading cause of failure after total shoulder arthroplasty. Although previously felt to be of little clinical significance, radiolucent lines around the glenoid prosthesis are now recognized as a sign of impending mid and long term fixation proble...

Fixation of the glenoid component is critical to the outcome of total shoulder arthroplasty. In an in vitro study, we analysed the effect of surface design and thickness of the cement mantle on the pull-out strength of the polyethylene pegs which are considered essential for fixation of cemented glenoid components. The macrostructure and surface of the pegs and the thickness of the cement mantl...

ont matter & 2006 006.10.004 thor. [email protected] Summary The treatment of combined glenohumeral arthritis and massive rotator cuff deficiency remains a unique challenge. Prosthetic reconstruction is aimed at restoring the normal kinematics of the glenohumeral joint. The reverse shoulder prosthesis medialises the centre of rotation of the glenohumeral joint, thereby lengthening the deltoid lev...

We report a rare case of disseminated coccidioidomycosis with multifocal musculoskeletal involvement. The patient presented to the emergency department with left shoulder pain and swelling. Magnetic resonance imaging of the left shoulder revealed enhancing soft tissue masses, bony lesions, and fluid collections in and around the glenohumeral joint with involvement of the proximal humerus, gleno...

History: This mare presented approximately seven years prior to euthanasia with lameness which progressed to swelling over the splint bones of the left forelimb. A bone scan showed intramedullary sclerosis of the left distal humerus occupying approximately one third of the bone and a suspected lesion of the glenoid cavity of the left scapula. The mare was treated with non-steroidal anti-inflamm...

Calcifying tendinitis is a common disorder related to deposition of hidroxyapatite crystals, which is most common around the shoulder joint, involving the supraespinosus tendon. It can however, affect almost any tendon at its insertion. Clinical features are variable and include pain and inflammation that often resolves spontaneously. We present a case of bilateral calcifying tendinitis of the ...
