Benign bone tumors and simple bone cysts (171 lesions in 170 cases) in the past seven years were treated by the packing of high porosity hydroxyapatite cubes (HA, 66%) or autogenous bone gaft (27%). After these procedures, three fractures and one late infection were seen but these were cured by casting or curettage.
Paching of HA alone was indicated especially for simple bone systs and metaphyseal benign bone tumors, while autogenous bone graft was indicated only for lesions requiring initial and permanent strength to prevent fractures.
