title: Management of osteonecrosis of the hip complicated with fracture: a case report.
abstract: A 47-year-old gentleman, with underlying seborrhoeic dermatitis that was treated with steroid therapy, and hepatitis B, presented with pain in his right hip. He was diagnosed with stage 2 osteonecrosis of the right hip (Ficat and Arlet classification). Core decompression and bone grafting was performed but recovery was complicated by a surgical site infection. Wound debridement, removal of bone graft and clearance of the bone tunnel were carried out. The patient was allowed to bear weight after surgery. Twelve days later, he developed right hip pain and radiographs showed fractured femur neck; the patient then underwent a two-stage total hip replacement (THR).
