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

Figure 1 Preoperatively a wide resection margin was planned ≥ 1 cm from the tumor margin.

Figure 2 To obtain adequate resection margin from tumor, the curved osteotomy is performed from middle to lower portion of the lesser trochanter to the tip of greater trochanter.

Figure 3 Radiographs of patient 3. A: Preoperative magnetic resonance imaging of a 64-year-old woman shows a high signal lesion confined to femoral head and neck; B: Postoperative radiograph at 6 wk after total hip arthroplasty with extensive excision at the intertrochanteric level shows an avulsion fracture of greater trochanter; C: Postoperative radiograph at 5 years after total hip arthroplasty with extensive excision at the intertrochanteric level shows no evidence of local recurrence and implant loosening or osteolysis.

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.
