Complications And Reconstruction Of Surgery For Pelvic Malignant Tumor

一, ObjectiveTo evaluate the complication and reconstructive technique of surgery for pelvic malignant tumor.二, MethodsFrom 1997 to 2005, 56 patients with pelvic malignant tumor underwent surgery. A concise typing refer to Enneking and Dunham's classification scheme was performed. After type I resection, 2 patients underwent implantation of an allograft, 1 patient had implantation of an autograft, 5 patients had implantation of autograft with TSRH and/or cement, and 3 patients had reconstruction of TSRH and cement. 36 patients underwent type II resection. There were 3 implantations of autograft or allograft and total hip endoprosthesis, 5 implantations of hip endoprosthesis alone, 3 implantations of saddle prosthesis and 25 resection arthroplastys. There was no reconstruction after type III resection. To analysis the results of complications and functional score for every type.三, Results3/11 patients with type I resection had complications. There was no significantdifference (p>0.05) in complications between with and without TSRH. Of the 36 patients with type II resection, 14 patients had complications. In total, 6/25 patients with resection arthroplasty, and 8/11 patients with prosthesis had complications, between which there was significant p<0.05. 1/6 patients with type III resection had complication. Postoperative function were similar between with and without TSRH after type I resection, and between with resection arthroplasty and prosthesis after type II resection. M ■? ConclusionBecause of the small number of complications and good function, reconstruction of TSRH and cement for metastatic tumor and implantation of an autograft with TSRH and/or cement for primary malignant tumor are advisable after type I resection;and resection arthroplasty is advisable after type II resection.
