im of this study to give idea about use of fresh homologous bone graft in filling cavities close to the lower

limb joints after curettage of benign and locally malignant osteolytic lesions. This study included 23 cases. The average age at operation was 14 years. The lesion was benign in 13 cases while locally malignant in ten cases. The fibular homologous graft was fixed by screws to the host bone when used to restore a deficient cortex or impacted in the middle of the cavity when applied to prevent collapse. Iliac homologous graft was used to fill the remaining parts of the cavity. The lower limb was supported either by cast or external fixator. The average duration of

follow up was 32 months

Satisfactory clinical results (excellent and good) were obtained in 19 cases (83%). Clinical failure occurred in 4 cases (17%).

The average radiological score was 74%. The average duration of radiological incorporation of the transferred fresh homologous graft to the host bone was 15 weeks. No rejection or deep infection occurred.
