Case 3: An 80-year-old woman. (A) Substantial sinking of an Austin-Moore stem was observed and the fracture was judged to be Vancouver type B2. (B) This patient was treated by an osteosynthesis using a locking plate instead of revision arthroplasty because of technical difficulty of performing revision arthroplasty owing to severe central migration of an Austin-Moore implant and subsequent severe hip contracture. (C) Sixteen months after the osteosynthesis. Bony union was obtained and her previous walking ability was recovered.
