The purpose of this study was to evaluate the stop screw method inserted with a minimal invasive technique in the treatment of flexible flatfoot in children.
We evaluated the results in a series of 21 flat feet in the age group ranging from 8 to 14 years between 1999 and 2007. The correction was evaluated clinically by assessment of heel valgus angle, range of motion of the ankle joint, and the photopodographic grading. The radiological assessment was performed by measuring the talonavicular angulation (Meary's line).
At time of follow-up there was significant improvement in the heel valgus angle during rest and during tiptoe standing, significant improvement in the dorsiflexion from neutral position, and in podographic grading. Radiologically talonavicular angulation improved significantly from 162+/-8.9 degrees preoperatively to 174+/-5.8 degrees postoperatively.
We can conclude that subtalar arthroereisis is relatively simple, effective, and minimally invasive procedure in treating flexible flatfoot in pediatric age.
本研究旨在评估微创技术中使用止动螺钉治疗儿童柔韧性平足的效果。
我们评估了 1999 年至 2007 年间 21 例 8 至 14 岁儿童柔韧性平足患者的治疗效果。通过评估足跟外翻角度、踝关节活动范围和足底照相分级来进行临床评估。影像学评估通过测量距跟角（Meary 线）来进行。
随访时，足跟在休息和踮脚尖站立时的外翻角度、从中立位的背屈度以及足底照相分级均有显著改善。影像学上距跟角从术前的 162+/-8.9 度显著改善至术后的 174+/-5.8 度。
我们可以得出结论，距下关节骨融合术是一种相对简单、有效且微创的治疗儿童柔韧性平足的方法。
