INTRODUCTION: In the reconstruction of extensive @entity79 after massive resection of @entity85 , the clinical results of moderately heat-treated autogenous bone graft have rarely been documented. We evaluated the remodelling and healing process of moderately heat-treated autogenous bone graft by means of imaging features. MATERIALS AND METHODS: The subjects of this study were 19 @entity1 with @entity2721 treated by heat-treated bone graft at our institution between 1992 and 2001, the mean follow-up period was 4.8+/-2.8 years (range 1-9 years). The remodelling and healing process of heat-treated bone graft was evaluated by means of radiography, bone scintigraphy, and MRI. RESULTS: The mean period to obtain bone union between host bone and grafted bone was 9.4 months. Infection was noted in 1 @entity1 , and @entity174 was present in 2 @entity1 . In 6 @entity1 , @entity1516 was found. Bone scintigraphy showed an increased uptake at the host-graft junction in the period between 3 and 36 months (median 10.7 months) postoperatively. A gradually increased diffuse uptake on the grafted side was evident at an average of 29.1 months (range 19-41 months) postoperatively. High signal intensity on T2-weighted images was observed in the early period after surgery, and iso-intense or low signal intensity became evident after an average of 28.3 months. A gradually increased diffuse uptake on scintigraphy and iso-intense or low signal intensity on T2-weighted images indicated remodelling of the grafted bone. CONCLUSION: Bone union of a moderately heat-treated autogenous bone graft was noted at about 9 months, and its remodelling was proceeding at about 30 months. This method will be useful for @entity79 after massive resection of soft-tissue and @entity3478 .
