Background: With the development of preoperative adjuvant treatment, imaging techniques, and improvement of surgical technique, limb salvage is now possible even in patients with pelvic tumors. However, reconstruction after periacetabular resection is complicated and challenging.
Methods: We retrospectively evaluated the usefulness of pasteurized autograft-total hip composite in pelvic reconstruction with regard to graft survival, union, graft-related complications, and functional outcome in 14 patients with periacetabular tumor.
Results: The 5-year and 10-year survival rates of the pasteurized bones were 64.3% and 32.1%, respectively. Major complications that necessitated graft removal included infection in three, fracture in two, and loosening in three patients. The average functional score of seven long-term successful patients was 25.6 (85.2%).
Conclusions: In spite of the high complication rate, pasteurized autograft can be considered as an option for periacetabular reconstruction in the selected patients who meet the following criteria. First, iliopectineal and ilioischial lines are radiologically intact; second, the tumor volume is small (preferably less than 100 ml).
