We radiographically examdned the results of bone grafting in 46 in hips lyear post-operahvely. We studied consolidation of grafted bone in the following situations: autografted femoral head and autografted ilium, tip-sized bone and block-sized bone, screw fixation and no screw fixation. Consolidation in autografted femoral head bone appeared as early as in the autografted ilium. Tip-sized bone consolidation may occur earlier than block-sized bone while consolidation seen in screw fixed bone appeared later than that seen in non-screw fixed bone.
