The Neck of Femur Fracture in an Elderly Patient with Schizophrenia and Parkinsonism Managed with Dual Mobility Total Hip Replacement – A Rare Case Report

Neck of femur fractures is the most common fractures in elderly people as they present with osteoporosis. There is a higher chance of proximal femur fracture in a schizophrenic patient as there is a loss of bone mineral density due to a drug-induced increase in the level of prolactin and immobility. Patients with Parkinson’s disease were at higher risk for the development of hip fractures due to gait disturbances and instability.Case Report: A 63-year-old male patient presented with complaints of the right arm pain, swelling, deformity of the right arm, and difficulty in extending the wrist for 3 days. The patient had a history of falls and trauma to the left arm at home. X-ray right arm showed distal one-third spiral humerus fracture for which intramedullary nailing was done. X-ray of the pelvis with both hips showed right neck of femur fracture with associated greater trochanter (GT) fracture. We managed with total hip replacement using a dual mobility cup and tension band wiring for GT fracture. Postoperatively, the patient has a good range of motion at the hip. The functional outcome is good as per Harris’s hip score.Conclusion: Neck femur fractures in elderly patients with associated comorbidities such as schizophrenia and parkinsonism are best managed with total hip replacement using a dual mobility cup. It avoids the risk of dislocation in high-risk patients and prevents secondary procedures. Careful clinical and radiological examination of the pelvis is very essential even in asymptomatic patients with a history of trauma to prevent delayed diagnosis of these types of fractures in patients with schizophrenia and parkinsonism.Keywords: Neck of femur fracture, Parkinsonism, schizophrenia, dual mobility cup, total hip replacement.
