Composite Ceramic Bone Graft Substitute in the Treatment of Locally Aggressive Benign Bone Tumours

Abstract

Composite bioceramic osteoconductive grafts, which combine porous HA with calcium sulphate, provide a framework for human osteogenesis and avoid donor-site morbidity (autologous bone graft harvesting). Tumour recurrence remains a major concern especially in young patients, as revision invariably requires removal of additional bone, potentially compromising joint integrity.
