To elaborate upon the complex variety of successful reconstructive techniques for limb salvage surgery for the management of aggressive juxta-articular and peri-acetabular bone tumors.

Limb sparing surgery, while complex, continues to gain wider acceptance among an increasing number of highly specialised musculoskeletal oncology surgeons.

The collective experience of the Musculoskeletal Sarcoma Group at The University of Calgary has utilised a variety of limb and joint salvage techniques in its armamentarium for reconstruction of such cases.

Whether malignant or benign, aggressive lesions occur at or near the joint resulting in marked subchondral bone destruction or pathologic fractures. comprehensive stepwise plan can result in a stable, pain free and functional joint with limb sparing.

The author has utilised local tumor removal and cementation with polymethylmethacrylate with and without secondary internal fixation. ome cases have been amenable to massive osteoarticular allografts, and more recently, tumor endoprostheses.

The North American experience with massive oncology prostheses is growing, resulting in increased opportunities for limb and joint salvage surgery with decreased morbidity and complications. his presentation will review the experience of the principal author’s work in limb and joint-sparing bone tumor surgery over the past 18 years.
