Abstract:
OBJECTIVE:To explore the efficacy of the resection of periacetabular malignant tumors and the reconstruction with modular endoprosthesis.
METHODS:From August 2006 to December 2012, 22 patients with periacetabular malignant tumors, who received the resection and reconstruction with modular prosthesis, were retrospectively reviewed. There were 11 males and 11 females, and the average age was 44 (16-65) years old. Pathological results showed there were 13 cases of chondrosarcoma, 5 cases of osteosarcoma, 2 cases of Ewing's sarcoma, 1 case of maligant fibrous histiocytoma, and 1 case of giant cell tumor. According to the classification system by Enneking, there were 11 cases of Type II+III resection, 5 cases of Type I+II+III resection, 3 cases of Type I+II resection, and 3 cases of Type II resection.
RESULTS:All patients were followed up. The average time for follow-up was 49 (11-103) months. At the last time of follow-up, 13 patients (59%) were still alive, 9 patients (41%) died due to their primary disease. Metastasis occurred in 8 patients (36%), and local recurrence occurred in 5 patients (23%). The mean Musculoskeletal Tumor Society (MSTS) score for 13 cases of alive patients at the latest time of follow-up was (18.5±5.7) months. The mean score for 11 patients, whose limb salvage were successful, was 20.7±2.0.
CONCLUSION:Reconstruction with modular prosthesis after wide resection for periacetabular malignant tumor can achieve satisfied outcome.
