Dual Mobility Cup in Fractures of the Femoral Neck in Neuromuscular Disorders and Cognitive Dysfunction Patients above 60 years-old.

Objectives: Dislocation rate of total hip arthroplasty (THA) can be as high as 20% for patients with fracture neck of femur, which is a disastrous complication in these vulnerable patients. Numerous techniques, including bipolar arthroplasty and constrained liner, have been adopted to minimize the risk of dislocation. We aimed to evaluate the role of dual mobility Cups in treating patients with fractures of the femoral neck with high risk of postoperative dislocation due to neuromuscular instability disorders.
