RESUMO
Wilson's disease (WD) is a rare inherited disorder of copper metabolism. It chiefly has hepatic, neurological and ophthalmic manifestations. Although osteoporosis, rickets and early arthritis are common features of WD, they are under-recognized. Musculoskeletal manifestations very rarely lead to diagnosis of the disease. Here we present a case of a 12-year-old girl who presented with a 3-month-old pathological fracture of neck of femur. WD was diagnosed on investigating the cause of the pathological fracture, which was managed by performing a conventional McMurray's intertrochanteric osteotomy. At 6 months follow up, fracture had united and patient was able to ambulate with support. WD can be a rare cause of pathological fracture. A high index of suspicion must be maintained in patients of pathological fracture presenting with associated neuropsychiatric or hepatic manifestations.
