067 REVERSE SHOULDER ARTHROPLASTY. INDICATIONS – CLINICAL RESULTS



Abstract

Although, reverse shoulder arthroplasty has initially been introduced for rotator cuff arthropathy, its application has been expanded on fracture sequelae, chronic dislocations and even comminuted fractures of the humeral head in elderly patients. The purpose of this study is to present our experience and the mid-term clinical results of this type prosthesis.

Between 2006 and 2008 16 reverse shoulder arthroplasties have been carried out in our department. Fourteen patients were female and 2 male with an average age of 72.4 years (55–81). Eleven patients had true rotator cuff arthropathy, 3 malunion of 4-part fractures, one chronic anterior shoulder dislocation and finally one patient had bilateral chronic posterior shoulder dislocation. In 2 cases we used the Delta prosthesis and in a further 14 cases the Aquealis Arthroplasty.

Routine postoperative follow up was at 3,6,12 and 24 months and included plain radiographic control and clinical evaluation with the Constant Shoulder Score. All patients report significant pain relief and an average improvement of the Constant Score from 40.5 to 72.3. Two patients had anterior dislocation of the prosthesis 4 days postoperatively and we proceeded to the application of a 9 mm metal spacer and bigger polyethylene size. In one patient neuroapraxia of the axillary nerve was observed; this resolved 3 months postoperatively. Continuous clinical improvement was observed in some patients up until 18 months postoperatively.

Our clinical results are very satisfactory and reveal that reverse shoulder arhroplasty is a very good option for a broad spectrum of pathologic shoulder conditions.
