Abstract:
Objective To investigate the correlation between surgical outcomes and body mass index (BMI) in patients with lumbar disc herniation. Methods 448 patients who underwent operative treatment for lumbar disc herniation were followed-up consecutively. The height and body weight of each patient was measured and recorded preoperatively. The BMI was calculated by the following formula, BMI=weight/height2 (kg/m2). The patients were asigned into three groups (normal group, BMI 28) based on the BMI. A questionnaire evaluation form was designed according to the 60 indexes put forward by North American Spine Association and the authors' clinical experiences. The post-operative signs and symptoms, living and working ability of the patients were evaluated by the questionnaire. Results Among the total 448 patients, none was lost for follow-up and all the patients were followed-up for average 2.48 (2.08-5.16) years. The improvement rate of the normal group was significantly higher than that of the obese group(P 0.05). The post-operative working ability of the patients in the normal group recovered more quickly than that of the patients in obese group (P 0.05). The remission rate, the post-operative pain and numbness between the male and the female were significantly different(P
