| 【Abstract】 Objectives: To evaluate the role of peak angle velocity(PAV) in a group of idiopathic scoliosis(IS) girls, and to search the multiple dimensional indicators in predicting the high risk of PAV. Methods: 30 IS girls with premenarche status, Risser 0, open triradiate cartilage, curve progression of 5° or more during follow-up and with at least 5 visits into our center were included. The average age at the first visit was 10.8 years. At each visit, the following data were collected and recorded: chronologic age, status of triradiate cartilage, Risser sign, height, the Cobb angle of major curve and digital skeletal age(DSA) score. Furthermore, the height velocity(HV) and angle velocity(AV) of each follow-up period were calculated. The logistic regression analysis was used to identify the independent indicators of PAV. Results: The average age was 11.8 years at PAV. The average height, DSA score and Cobb angle at PAV was 150.7±4.8cm, 479.4±56.5 and 26.5±7.2°, respectively. The average HV and AV at PAV was 8.3±3.7cm/year and 7.8±5.2°/year. Additionally, the Risser sign was 0 and 1 in 80.0% patients and 20.0% patients at PAV, respectively. According to the logistic regression model, chronologic age between 11 and 13 years(OR=3.166, P=0.032), closed triradiate cartilage(OR=6.365, P<0.01), Risser 0(OR=12.963, P<0.01), DSA score between 400 and 500(OR=10.758, P=0.011), HV >6cm/year(OR=4.346, P=0.025), Cobb angle of major curve >30°(OR=9.535, P=0.013) were significantly correlated with the occurrence of PAV. Conclusions: Multiple dimensional indicators together predict the PAV in IS girls including age between 11 and 13 years, Risser 0 with closed triradiate cartilage, DSA score between 400 and 500, HV more than 6cm per year and Cobb angle of major curve more than 30°. |
