Periprosthetic fractures are rare complications (0.3%–2.5%) of total knee and hip Arthroplasty. Purpose of this study is to present our experience and the mid-term clinical results of periprosthetic fracture care.

Between 2005 and 2009 nineteen femoral periprosthetic fractures were treated in our department. Seven patients with TKA had supracondylar fractures, type II according to Lewis and Rorabec classification. Twelve patients with THR had type B2 fractures according to Vacouver Classification. Seven patients were men and 12 women with average age 78.15 years. Femoral shaft fractures were treated with ORIF and DCP 4.5mm femoral plate in 8 cases, revision THR in 3 cases and 4.5mm plate with wires in one case. Supracondylar fractures were treated with ORIF abd LCP plate 4.5mm in 5 cases, Ilizarov fixator in one case and DCS plate in the last case. The average follow up was 22 months postoperatively.

Fracture healing observed in 16 patients at an average of 6 months postoperatively. No infection or non union complicated our treatment goal. Three patients died at an average of 2 months postoperatively. One should point out that mobilization and return to previous activity level is very difficult for these patients, despite fracture healing. Best clinical results observed with DCP and LCP 4.5mm plates.

Periprosthetic fractures are serious and complex complications of an arthroplasty that require stable osteosynthesis and primary patient mobilization.
