No results posted yet for this study

Summary

Our aim is to develop a strategy that reduces the risk of dislocations after total hip arthroplasty surgery performed due to femoral neck fracture. We therefore perform a register-nested, pragmatic, randomized controlled trial to investigate the safety and efficacy of dual mobility cups that were designed to minimize the risk of dislocation in the large and fragile group of elderly patients with femoral neck fractures.

Conditions

  • Femoral Neck Fractures

Interventions

DEVICE

Dual mobility cup

Patients with a displaced femoral neck fracture eligible for THA receive a dual mobility cup, as opposed to a standard cup in the control group.

DEVICE

Standard cup
