  Purpose

Patients younger than 70 years with a displaced femoral neck are in serious conditions. The femoral neck fracture is associated with low activity levels, hip pain and substantially reduced quality of life. Relatively young individuals with low-energy fractures tend to have additional morbidity or lower bone quality. The literature indicates that 5 % of all displaced femoral neck fractures are in patients aged 55 - 70 years. Little research and lack of consensus and guidance about appropriate treatment of these patients renders choice of treatment, and the health economic aspect a great challenge. In this study the investigators aim to answer if patients aged 55 - 70 years with displaced and low-energy femoral neck fractures treated with a total hip arthroplasty leads to a better functional outcome than osteosynthesis, and can patient-related factors be identified that predispose for femoral fracture? It is a randomized multi center study of patients operated with either total hip arthroplasty or osteosynthesis in which functional outcome, complications and reoperations are compared for the 2 groups. Additional controls are done after 4 and 12 months; 2 and possibly after 3, 5, 10, 15 and 20 years. Map patient - related factors that predispose for displaced femoral neck fractures for patients aged 55 - 70 years. Map bone density measured with Dexa for two types of surgical procedures. Map complications and functional outcome after osteosynthesis or total hip replacement in patients aged 55 - 70 years with displaced femoral neck fractures.
