[Resection and reconstruction for tumor of pelvic ring].
OBJECTIVE
To discuss the resection of tumors of pelvic ring and its reconstruction of defects.


METHODS
From January 1999 to December 2006, 48 patients with tumors in pelvic ring were treated and defects were reconstructed. There were 32 males and 16 females, aged 14-72 years (mean 45.1 years), including 12 cases of benign tumor and 36 cases of malignant tumor. Fourteen cases had lesions in region I, 11 cases in region II, 12 cases in region III, 3 cases in region IV and 8 cases had two or more regions. The selection of surgical method: benign tumor in wing of ilium or in sacro-iliac articulation was curettaged, malignant tumors were resected radically or boardly. Benign or malignant tumor in pubis, ischium or pubic symphysis was resected radically, defects were reconstructed with plastic plate or not. For tumor affecting aceta bulum resection of tumor and replacement of the peri-pelvic prothetic or artificial hip joint replacement were performed to reconstruct the function of hip joint.


RESULTS
Twelve patients with benign tumors were followed up 12-72 months and could walk well, only 1 case relapsed locally. Thirty-six patients with malignant tumor were followed up 6-72 months, the survival time was 6-12 months in 2 cases (5.6%), 12-24 months in 2 cases (5.6%), 24-36 mongths in 6 cases (16.7%), 36-72 months in 14 cases (38.8%), and more than 72 months in 12 cases (33.3%); 28 patients (77.8%) could walk normally, 6 (16.7%) could walk with the help of walking stick, 2 (5.5%) needed wheel chair to move. Complications occurred in 6 cases (including 2 venous thrombus, 1 anoxic encephalopathy, 2 wound delayed healing, and 1 dislocation after total hip joint replacement); the patients' condition took a turn for the better.


CONCLUSIONS
Operation is a favorable way for the treatment of pelvic tumor. Selecting convenient operation methods to resect tumors or reconstruction defects according the position of the tumor will do good favor to good results, increase the survival time and improve quality of life.
