Abstract

Abstract:

BACKGROUND: Posterior orthopedic surgery is the more effective treatment of adolescent idiopathic scoliosis. However, there is rare study on the correction extent of spinal height and influential factors after posterior orthopedic surgery in patients with adolescent idiopathic scoliosis.
OBJECTIVE: To explore the effect and influencing factors of posterior orthopedic surgery on adolescent idiopathic scoliosis.
METHODS: Data of 346 adolescent idiopathic scoliosis patients were retrospectively analyzed. There were 203 cases in the single bend group and 143 cases in the double bend group. Cobb angle and vertebral column height were measured before and after orthopedic surgery. Stepwise regression analysis was used to explore the relationship of gender, age, weight, preoperative and postoperative spinal height, preoperative Cobb angle, Cobb angle correction value, Cobb angle correction rate, the number of fused joint, spine curved single or double bend, Lenke classification with the increased value of spinal height after surgery.
RESULTS AND CONCLUSION: Cobb angles of single and double bend groups were significantly smaller after surgery than the preoperative angles (P < 0.05), but spinal height was significantly higher after surgery than that before surgery in both groups (P < 0.05). With the increase in the preoperative Cobb angle, the reduced value of
Cobb angle (ΔCobb) and the increase in spinal height (ΔSH) were significantly increased (P < 0.05). Multiple linear regression analysis results showed Cobb angle correction value, preoperative Cobb angle, postoperative spine height, Lenke type, single curved or double curved spine, and age had significant effects on increased value of spine height (ΔSH) after treatment (P < 0.01). The corrected value of Cobb angle was the greatest influential factor. These findings indicate that posterior correction has significant effects on adolescent idiopathic scoliosis. Factors affecting the increased value of spine height include Cobb angle, preoperative Cobb angle, postoperative spine height, Lenke type, single curved or double curved spine and age.
