Management of shoulder periprosthetic fractures: our institutional experience and review of the literature.
Fractures of the humerus in patients with total shoulder replacement are rare and difficult to treat. The treatment of periprosthetic humeral fractures depends on the location of the fracture in relation to the humeral stem and the stability of the stem/bone interface. We wished to determine the treatment outcomes in a series of patients managed in our institution with periprosthetic humeral fractures. We also carried out a review of the literature. Over a 5 year period, out of 10 patients, 7 were available at the final follow up with a mean age of 72 years (range 68-75). A fall from standing height was the most common mechanism of injury. All patients were found to have stable prosthesis in situ and were treated with angular stable plates and cerclage wiring. The mean time from the total shoulder replacement to injury (fracture) was 11.2 months (range 8-21). All fractures united without complications at a mean time of 5.1 months (range 4-6). The literature review revealed a limited number of publications reporting on the management of approximately 40 patients. The outcome noted in these patients is also presented.
