摘　　要：目的:探讨影响8字板治疗儿童膝关节冠状面畸形矫正速度的相关因素。方法:回顾性分析2015年1月-2023年1月采用8字钢板治疗的114例下肢冠状面畸形(膝内翻或膝外翻)患儿的病例资料。根据术前和术后定期随访的X线片,测量股骨远端外侧角(aLDFA)、胫骨近端内侧角(aMPTA)。对患儿一般资料及可能影响8字板治疗效果的相关因素进行研究。结果:平均校正速度为每月0.57°,平均年龄9.78岁。单因素分析显示,年龄、放置时间、体质量与矫正速度呈负相关,股骨远端矫正速度较胫骨近端快(P=0.039)。多元线性回归显示,矫正速度受手术年龄、阻滞部位、放置时间影响显著(均P<0.05);股骨远端每月的矫正速度比胫骨近端高0.23°;年龄与放置时间的改变与矫正速度呈负相关。结论:8字板半骨骺阻滞矫正儿童膝关节冠状面畸形矫正速度与手术年龄、放置时间、阻滞部位相关。临床治疗需根据患儿自身情况综合考虑,术后应密切随访。Objective:To investigate the factors affecting the speed of correction of coronal deformity of knee joint in children treated with figure 8 plate.Methods:Data of coronal surface malformations of lower limbs(varus or valgus)treated with figure-8 plates from January 2015 to January 2023 were retrospectively analyzed.The lateral Angle of the distal anatomic axis of the femur and the medial Angle of the proximal tibia were measured in 114 cases of epiphysis.The general information of patients and the related factors that may affect the therapeutic effect of 8 plate were studied.Results:The average correction speed was 0.57°per month and the average age was 9.78 years.Univariate analysis showed that age,placement time and body weight were negatively correlated with the correction speed,and the correction speed of the distal femur was faster than that of the proximal tibia(P=0.039).Multiple linear regression showed that the speed of correction was significantly affected by surgical age,block site and placement time(all P<0.05).The monthly correction rate of the distal femur was 0.23°higher than that of the proximal tibia.Age and time of placement were negatively correlated with the speed of correction.Conclusion:The speed of correction of coronal deformity of knee joint in children with hemiepiphysial block correction was related to the age of operation,the time of placement and the block site.Clinical treatment should be considered according to the patient's own situation,and close follow-up should be conducted after surgery.
