Proximal femoral fractures are a typical pathology in elderly patients after a low-energy trauma.
This study analyses preexisting risk factors for proximal femoral fractures as well as for failing to reach the previous functional level, difference in outcome between patients with femoral neck fracture compared to those with pertrochanteric fracture, surgical performance and its significance for the functional outcome, as well as the impact of proximal femoral fractures on patients' one-year independence.

| Change in patient clinical outcome (according Penrod score) | Penrod score reflects the patients' preoperative functional level and living. Patients are classified concerning their prefracture age (1: <75 years, 2: 75-84 years, 3 ≥85 years, their ability in performing activities of daily life (ADL) as well as their cognitive status (dementia in clusters 2B and 3D Situation) | preoperatively and at 1 year follow up date after surgery |
