Preliminary results of 3D printed corrective insoles for the treatment of flat feet in children

摘要:

［目的］评价手法整复结合 3D 打印定制鞋垫治疗儿童扁平足的效果。［方法］2020 年 12 月—2022 年 6 月，对 56 例扁平足儿童给予手法整复。依据医患沟通结果，31 例（62 足）配制 3D 打印定制鞋垫，25 例（50 足）未配制定制鞋垫。比较两组舒适性、稳定性和满意度视觉模拟评分（visual analogue scale, VAS），美国足踝骨科协会( AOFAS) 评分，以及足印的 Clarke 角（CA）、Staheli 指数（AI）、Chippaux-Smirak 指数（CSI）和足弓面积指数。［结果］治疗 12 和 18 周时，定制垫组舒适性、稳定性和满意度 VAS 评分均显著优于无鞋垫组（P<0.05）；18 周时，定制垫组 AOFAS 评分显著优于无鞋垫组（P<0.05）。与手法治疗前相比，手法治疗后两组 CA、AI、CSI 和足弓面积指数均显著改善（P<0.05）。18 周后两组 CA、AI、CSI 和足弓面积指数的矫正均有显著丢失（P<0.05）。18 周后定制垫组的足弓面积指数显著优于无鞋垫组（P<0.05），但两组间 CA、AI 和 CSI 的差异无统计学意义（P>0.05）。［结论］手法整复结合 3D 打印定制鞋垫可提升儿童扁平足生活质量。

Abstract:

[Objective] To evaluate the preliminary outcome of manipulative correction combined with 3D printing customized insoles for flat feet in children. [Methods] From December 2020 to June 2022, 56 children with flat feet were treated with manipulative correction. After that, 31 children (62 feet) received 3D printing customized insole, while the remaining 25 children (50 feet) not used the insole accord- ing to the consequence of doctor-patient communication. The visual analogue scales (VAS) for comfort, stability and satisfaction, and AO- FAS score, as well as the Clarke angle (CA) , Staheli arch index (AI) , Chippaux-Smirak index (CSI) , arch area index were compared be- tween the two groups. [Results] The insole group proved significantly superior to the non-insole group in terms of VAS scores for comfort, sta- bility and satisfaction 12 and 18 weeks after treatment, and the AOFAS score 18 weeks after treatment (P＜0.05) . Compared with those be- fore manual therapy, the CA, AI, CSI and arch area index significantly improved in both groups after therapy (P＜0.05) , whereas which signif- icantly lost 18 weeks after treatment (P＜0.05) . At 18 weeks after treatment, the insole group was significantly better than the non-insole group in term of arch area index (P＜0.05) , but there were no significant differences in CA, AI and CSI between the two groups (P＞0.05) . [Conclusion] The manipulative correction combined with 3D printing customized insoles might improve quality of lives in children who suf- fer from severe flat feet
