Abstract：BACKGROUND:Idiopathic scoliosis is most common among al the scoliosis. Accompanied by the nervous system, the endocrine system as wel as nutritional and metabolic abnormalities, patients usual y cannot be redressed and cured by conservative treatment, but often require surgical operation. Surgery for malformation is a very complicated project, and is real y of great significance for an in-depth research on treatment and turnover of idiopathic scoliosis. <br> OBJECTIVE:To observe the correction effect of posterior screw-rod fixation for idiopathic scoliosis, and explore the relevant factors influencing its effectiveness. <br> METHODS:We retrospectively analyzed 80 cases receiving pedicle screw fixation in the treatment of idiopathic scoliosis in the latest four years. Age, gender, disease duration, preoperative and postoperative X-ray measurement of coronal Cobb’s angle, and trunk deviation were recorded, and statistical y analyzed. <br> RESULTS AND CONCLUSION:Univariate analysis showed that gender and disease duration were not significantly correlated with postoperative correction results (P>0.05). However, the age distribution of patients, the location of scoliosis, and scoliosis flexibility were associated with curative effects of internal fixation (P<0.05). Posterior screw-rod fixation for idiopathic scoliosis can achieve significant effects. The patient’s age, location and flexibility of scoliosis have a significant effect on the effects of fixation. The patient’s gender and disease duration had no significant effect on fixation effects.
