[Mantel transplant for defect reconstruction after resection of malignant bone tumors of the lower extremity].

We treated 11 patients with primary sarcoma and 1 patient with enchondroma of the femur or tibia. Bridging the osseus defect we used an intercalary allograft shell and contralateral fibula as described by Capanna et al. [7]. The median bone defect after resection of the tumor was 15.7 (9.0-28.5) cm, average follow up was 29.2 (13-56) month. Anastomosis of the autologous fibula was successful in 8 cases. There were 3 cases necessitating later amputation. The other cases showed good clinical (Enneking-score) and radiological (ISOLS-score) results. These results indicate the described technique as a suitable method for defect reconstruction with good functional outcome.
