Management of periprosthetic fractures: the shoulder.

The incidence of periprosthetic fracture during or after shoulder arthroplasty is 1% to 3% of all shoulder arthroplasties. The frequency with which this injury occurs may be increasing, however. Contemporary implants have been designed specifically for uncemented use and often have larger proximal bodies. During insertion, attempts are made to achieve a tight, line-line fit. Consequently the risk for periprosthetic fracture may be higher than estimated. Copyright 2002, Elsevier Science (USA).
