The management of the defect following curettage of benign bone tumour is a problem to the orthopaedic surgeon. The usual practice of using autologous bone graft has problems like insufficiency, donor site morbidity, longer operation time etc. The search for ideal bone graft substitute is on. The present series is of 23 cases of benign bone lesions who underwent curettage and filling with calcium hydroxyapatite. GCT and its variants predominated the type of lesions. The age group was three to 62 year. There were three pathological fractures. The involved sites varied from proximal humerus, phalanges of hand, femoral head and neck, femoral condyles, proximal tibia, distal tibia, calcaneum. Three cases were lost to follow-up. One case died due to other causes. These patients were followed up for a period ranging from 24 to 50 months. The main difficulty was in assessing the incorporation of the hydroxyapatite crystals. We had three excellent, two fair and 13 good results.
