Periprosthetic femoral fracture - an interdisciplinary challenge

The increasing implantation rates of total hip and knee prostheses have been accompanied by a corresponding rise in periprosthetic fractures (PPF), most often affecting the femur.

This review is based on a selective search of the PubMed database for articles in English and German. The search was carried out with a set of pertinent medical subject headings (MeSH) and as a free text search employing a logical combination of search terms (evidence grade III-IV).

Soft-tissue-sparing, stable-angle plate osteosynthesis with a firmly seated implant is a safe treatment of periprosthetic femoral fracture (PPFF). A correct assessment of the stability of the prosthesis is a prerequisite for the success of treatment. A loose prosthesis must be surgically revised, and a failed osteosynthesis can also necessitate revision of the prosthesis. The conservative management of PPFF is generally not indicated, as it has a high complication rate.

The treatment of periprosthetic fractures requires competence, not just in osteosynthetic techniques, but also in endoprosthesis implantation and revision. Careful preoperative planning to select the proper treatment is essential, and the necessary equipment must be on hand.
