[Periprosthetic fractures of the proximal femur]

Abstract

The incidence of periprosthetic fractures of the proximal femur is increasing due to the growing numbers of hip replacements in old age. The treatment of these fractures is a challenge for the treating physician and standardized procedures are necessary. The unified classification system (UCS) is a suitable tool to establish treatment strategies: On the basis of the fracture localization and extent, bone quality, stability of the prosthesis and the presence of further implants, the fractures can be classified according to the UCS and a treatment algorithm can be derived. This article gives an overview of the diagnostics, classification and characteristics of the various periprosthetic fracture types as well as the treatment.
