Bone Graft Vs Bone Substitutes in Treatment of Cavitary Benign Bone Tumors

Abstract

Extended curettage is the commonest mode of the treatment of the cavitary benign bone tumors. If a tumor is very large and threatening to involve the joint, complete excision with joint reconstruction may be necessary. Cure rates of 90‑95% have been achieved using curettage as the sole mode of treatment in benign bony lesions. (51, 97) However this treatment is not devoid of controversy and many authors recommend that bone defect after curettage of benign bone tumors should be filled with bone grafts or substitutes such as cement, hydroxyapatite, or tricalcium phosphate. (85) Autografts are free of disease transmission or immunological reactions and have properties of osteogenesis, osteoinduction and osteoconduction, but are associated with the donor site morbidity (54)
