title: The Saddle prosthesis in periacetabular tumours.
abstract: The Saddle endoprosthesis provides a means of establishing a stable and mobile articulation between the femur and a partially resected pelvis. Six patients with malignant or aggressive benign bone tumours underwent resection and replacement with custom-made Saddle endoprosthesis. Wide margin was achieved in four cases and marginal margin in two. Follow-up ranged from 24 to 41 months. All the six patients were then alive, five being disease-free. One patient developed deep infection and local recurrence necessitating removal of the prosthesis. The functional results were either excellent or good in five patients.
