Reconstruction in orthopaedic oncology: frontier and horizon

Abstract

Reconstruction is the essential part of limb-salvage surgeries for bone and soft-tissue sarcomas. With the progress in the past decades, abundant experiences have been accumulated in reconstruction for the proximal femur, the proximal humerus, the elbow, the knee and the pelvis. However, improvements of functional status and prevention of complications are still in need, which demands a theoretical system to instruct and evaluate new conception for reconstruction. To this aim, we propose the ‘MAFOS’ model, which are the initials of Materials, Articulation, Fixation, Osseointegration and Soft-tissue reconstruction. The ‘MAFOS’ model can guide us to inspect the rationality of new methods or designs, and thus can reduce the risk of reconstruction failure.
