Trochanter/calcar preserving reconstruction in tumors involving the femoral head and neck

Figure 4 Radiographs of patient 1. A: Radiograph of a 36-year-old woman shows an osteolytic lesion confined to femoral head and neck; B: Preoperative magnetic resonance imaging shows a low signal intensity lesion with well-defined surrounding rim; C: Postoperative radiograph at 6 years after total hip arthroplasty with extensive excision at the intertrochanteric level shows no evidence of local recurrence and implant loosening or osteolysis.
