Abstract:
Objective:To observe the clinical effects of resection and different reconstruction methods of malignant tumors around the ilium (Ⅰ region, Ⅰ+Ⅱ region and Ⅰ+Ⅳ region).Methods:The clinical data of 23 patients with resection and reconstruction of malignant tumors around the ilium in the Second Hospital of Shanxi Medical University from January 2012 to December 2017 was retrospectively analyzed. All patients received pelvic tumor resection and screw-rod system fixation, and some patients received bone graft or cement reinforcement at the same time. The clinical effect, survival rate, complications and limb function score were statistically analyzed.Results:All cases were followed up for 10-79 months (median 42 months). Eleven patients survived, the 1-year overall survival (OS) rate was 82.6% (19/23), the 3-year OS rate was 65.2% (15/23), and the 5-year OS rate was 52.2% (12/23). The 3-year OS rate was 70.6% for the patients without acetabulum involvement, and 57.1% for those with acetabulum involvement, and the difference between the two groups was statistically significant (χ 2 = 4.182, P = 0.041). Seven cases complicated with wound nonunion, dislocation and other complications. The postoperative functional score of patients with pedicle screw-rod fixation and reconstruction was (23.6±1.3) points, and the postoperative functional score of patients with ordinary semi-pelvis and nail-rod semi-pelvic reconstruction was (18.1±1.4) points, and the difference between the two groups was statistically significant (t = 9.42, P < 0.01). Conclusion:For the bone defect after resection of tumors around the ilium, the clinical effect of pedicle screw-rod fixation is better than that of nail-rod semi-pelvic reconstruction.
