Surgical treatment and reconstruction of pelvic tumors

OBJECTIVE: To investigate the efficacy of reconstructing the stability of the pelvic ring by selecting the appropriate surgical methods for pelvic tumors according to their sites of occurrence. METHODS: Postoperative clinical retrospective analysis was performed on 8 patients with pelvic tumors. The Enneking division of pelvic tumors was 5 cases of pure zone I tumors, 1 case of simultaneous invasion of zone I and zone II, 1 case of zone II tumor invading the sciatic branch at the same time, and 1 case of zone II tumor invading the sciatic branch and pubic bone branch at the same time. There were 2 cases of chondrosarcoma, 2 cases of malignant fibrous histiocytoma, 1 case of osteosarcoma, 1 case of aneurysmal bone cyst, 1 case of giant cell tumor of bone, and 1 case of metastatic adenocarcinoma of bone. Bridging reconstruction with autologous iliac bone or allograft bone was performed after resection of zone I tumor, and acetabular reconstruction, customized personalized artificial prosthesis and total hip replacement were performed after resection of zone II tumor. RESULTS: All eight patients were followed up after surgery for an average of 12 months, and all cases were able to retain partial function of the affected limb and pelvic stability. CONCLUSION: The choice of different pelvic stability reconstruction after tumor resection in different regions can maximize the preservation of limb function and improve the quality of survival.
