Periprosthetic Fractures of the Femur Treated by Osteosynthesis

Study Overview
=================
Brief Summary
-----------------
Observational retrospective study on 36 consecutive patients having had surgery for a periprosthetic fracture of the femur between 2010 and 2015. The goal of the study is to test whether osteosynthesis was a secure choice at a certain age and with any type of Vancouver fracture.
