Although autoclaved autogenous bone reconstruction is one of the established procedures, it may have some problems in bone regeneration and mechanical property. The purpose of this study is to evaluate the efficacy of more biologic and anatomical reconstruction where allograft is not readily available. From Aug.1991 to Feb. 1996 the authors analyzed 32 cases of reconstruction with autogenous low heat treated bone. Autogenous graft sites were humerus 4, tibia 4, pelvis 9, and 15 femur. Average follow-up period was 23(range; 12-51) months. There were 49 graft-host junctional sites. Diaphysis was 22, metaphysis 10, and flat bone 17. Average duration of healing for the 38 united sites was 7 months. Average union time for each anatomical area 8 months in 19 diaphysis, 12 months in 7 metaphysis, and 12.7 months in 12 flat bone pelvis). Eleven nonunion sites consisted of 3 diaphysis(3/22), 3 metaphysis(3/10), and 5 flat bone(5/17). Complications other than nonunion were local recurrence(4), bone resorption(3), graft fracture(2), osteomyelitis(1), metal failure(2), and wound infection(1). Initial bone quality and stable fixation technique was important for union rate. Plate and screw is a good method for diaphyseal lesion. Metaphyseal and flat bone are weak area for rigid fixation and one stage augumentation with iliac bone graft can be a salvage procedure.
