A Rare Case of Metabolic Disorder of Bilateral Fracture Neck Femur Treated with Bilateral Total Hip Arthroplasty

Introduction: Bilateral intracapsular neck of femur fractures are rare and are usually associated with underlying metabolic bone diseases such as osteomalacia or osteoporosis. Direct anterior approach (DAA) total hip arthroplasty (THA) is considered the treatment of choice for displaced intracapsular fractures of the femoral neck in both elderly and selected young patients with poor bone quality. Performing THA on both sides in a single sitting can facilitate early mobilization and reduce hospital stay. Case Report: We report a case of a 40-year-old male who presented with bilateral displaced intracapsular neck of femur fractures following a fall from bed at home. The patient underwent bilateral THA through the DAA in a single sitting. The post-operative course was uneventful. Full weight-bearing mobilization with walker support was started on the 1st post-operative day. By 3-4 weeks post-surgery, the patient had resumed independent activities of daily living. Conclusion: Simultaneous bilateral DAA-THA can provide excellent clinical and functional outcomes in carefully selected patients with bilateral neck of femur fractures of metabolic origin. Performing arthroplasty on both sides in a single sitting enables early rehabilitation and better functional recovery.
