Shepherd’s Crook Deformity with Pathological Femur Neck Fracture in a Patient with Fibrous Dysplasia Managed with Proximal Femoral Nailing and Valgus Osteotomy

Abstract

Fibrous dysplasia is a rare condition in which bone is replaced by fibroosseous tissue. It is a benign condition, divided into monostotic and polyostotic fibrous dysplasia, which accounts for about 5-7% of all benign bone tumours. Here, authors reported a case of a 38-year-old male that presented with left hip pain since 15 days and had a history of trauma. X-ray pelvis and Magnetic Resonance Imaging (MRI) showed shepherd’s crook deformity in the left proximal femur with pathological femur neck fracture. It was managed with valgus osteotomy for deformity correction and fracture fixation using long proximal femur nail and cannulated cancellous screws. At one and half year follow-up, the patient showed good hip and knee range of motion with no complications
