Objective To investigate the clinical and long-term effects of semi-pelvic replacement on pelvic malignancies. Methods Seventeen patients with malignant pelvic tumor who underwent semi pelvic replacement in our hospital from 2005 to 2009 were observed and followed up for a long time. Results All the 17 cases were operated without any death, with an average blood loss of 2700ml. Three patients died of tumor recurrence within 3 years after follow-up. There were 6 cases of complications, including 2 cases of deep infection, 1 case of prosthesis dislocation, Flap transfer in 3 cases; the last follow-up evaluation of functional outcome by Enneking method, excellent in 1 case, good in 5 cases, fair in 6 cases and poor in 3 cases. Conclusions Semi-pelvic replacement is an effective method for the treatment of pelvic malignant tumors. It is the key to the successful treatment to remove the tumor according to the size and degree of the lesion during the operation. Based on this, the reasonable selection of the prosthesis is the successful design and evaluation Necessary conditions.
