Abstract
The subjects were 7 cases (3 males, 4 females). The mean age was 62 years (range; 45 to 75 years) and the mean follow-up period was 13.1 months (range; 7 to 25 months) postoperatively. Bone defects of the femur were type II (1 case); and type III (6 cases) according to AAOS classification. Cortical bone defects were covered with autogenous iliac cortical bone, and cancellous bone or allograft were inlay grafted to the intramedullary cavity. Long extensively porous coated stems and proximally porous coated stems were employed in 4 cases and 3 cases respectively. Allograft was used in 3 cases. These cases were evaluated clinically using the JOA score and evaluated radiographically based on Engh's criteria.
All the cases improved clinically, and 6 cases were stable on the radiographic evaluation. In one case with marked bone defect in which femoral reconstruction was performed with the proximally porous coated stem, stem subsidence occurred in on early period after the operation. Only this case was evaluated as unstable.
For the revision of the femur with severe bone defect, femoral reconstruction with cementless stem is considered desirable.
