Uncemented metal-back glenoid component in revision of aseptic glenoid loosening: a prospective study of 10 cases with a minimum follow-up of 2 years.

Introduction: Glenoid component loosening comprises 25 % of all complications related to total shoulder arthroplasties (TSA). This prospective study was undertaken to assess the accuracy of an uncemented metal-back glenoid component in cases of revision of aseptic glenoid loosening.

Materials And Methods: Between September 2007 and January 2010, a total of ten patients with symptomatic glenoid loosening after TSA (7 cemented and 3 non-cemented) underwent revision surgery with an uncemented metal-back glenoid component (MB).

Results of 30 reverse shoulder prostheses for revision of failed hemi- or total shoulder arthroplasty.

Purpose: Revision surgery for shoulder prosthesis remains a difficult task in shoulder surgery. The purpose of this retrospective study was to evaluate the clinical and radiological outcomes of a series of 30 reverse shoulder prostheses performed as revision of failed hemi- or total shoulder arthroplasty. The most relevant technical points in surgery are described, as are other surgical options; a rational strategy for the treatment of these patients is proposed.

New design of a cementless glenoid component in unconstrained shoulder arthroplasty: a prospective medium-term analysis of 143 cases.

The uncemented glenoid implants in total anatomical shoulder arthroplasty are likely to be accused of problems like dissociations, secondary rotator cuff tear, and wear of polyethylene (PE). This work is a clinical and radiological prospective review of 143 cases of anatomical total shoulder arthroplasty using a new metal back uncemented glenoid implant (MB) in order to see if this new implant induces those complications. A total of 143 cases were operated between 2003 and 2011.

Do less medialized reverse shoulder prostheses increase motion and reduce notching?

Background: Cuff tear arthropathy is the primary indication for total reverse shoulder arthroplasty. In patients with pseudoparalytic shoulders secondary to irreparable rotator cuff tear, reverse shoulder arthroplasty allows restoration of active anterior elevation and painless shoulder. High rates of glenoid notching have also been reported.

Reverse shoulder arthroplasty: does reduced medialisation improve radiological and clinical results?

The purpose of this retrospective study was to assess the effect of the reduced medialisation of the Arrow reverse shoulder prosthesis on short-term clinical and radiological results. The clinical and radiological results of 47 Delta III reverse prostheses and 49 Arrow reverse prostheses were retrospectively compared at a minimum of twelve months follow-up. There was a significant increase (p < 1.
