Unusual presentation of recurrent subtrochanteric non-union in a patient with hip arthrodesis: A case report

Subtrocantheric nonunion following fracture of an arthrodesed hip: a case report

In recent years in the era of successful of total hip replacement, hip arthrodesis is rarely performed. The anatomy and biomechanics of an arthrodesed hip is altered, thus influencing the treatments strategies in case of fracture or nonunions. This case report describes the management and therapeutic solution for the treatment of subtrochanteric nonunion in a patient with hip arthrodesis. Satisfactory outcomes were finally obtained after a double surgical procedure.

Total Hip Arthroplasty for Femoral Neck Fracture after Postoperative Intertrochanteric Fracture in a Patient with Spontaneous Fused Hip

A 64-year-old woman with a spontaneous fused hip sustained a left femoral neck fracture. It was revealed that her left hip joint had a long-standing spontaneous hip fusion due to end-stage osteoarthritis. Additionally, she sustained an ipsilateral femoral intertrochanteric fracture and underwent osteosynthesis using a dynamic hip screw 8 years ago. The one-stage THA was successfully treated with no major complications and good functional recovery was obtained. The hip range of motion improved remarkably at one year after surgery. The Modified Harris Hip Score improved from an estimated 70 points before fracture to 95 points at final follow-up.
