The aim of this study is to report the long-term outcomes of a homogenous series of patients who underwent subtalar arthroereisis (STA) for the treatment of symptomatic flexible flatfoot (FFF).
Thirty-four pediatric patients who underwent STA with a bioabsorbable implant were enrolled and radiographic measurements, clinical outcomes, and patients' satisfaction were evaluated.
At a mean 180 months follow-up, radiographic measurements showed significant improvement. A physiological footprint and a proper hindfoot alignment were shown in more than 70% of patients. Mean AOFAS score was 90.4 ± 9.2 (72-100), mean SF-12 was 44.7 with 30 out of 34 patients (88.2%) satisfied with the procedure.
STA with a bioabsorbable implant showed satisfactory long-term results. Based on the data subgroup analysis, nine to 11.5 years for female and nine to 13.5 years for male appeared to be the most appropriate age for surgery.
本研究旨在报告一组接受距下关节融合术（STA）治疗症状性柔韧性平足症（FFF）的同质患者的长期结果。
纳入了 34 名接受生物可吸收植入物 STA 的儿科患者，并评估了影像学测量、临床结果和患者满意度。
在平均 180 个月的随访中，影像学测量显示出显著改善。超过 70%的患者显示出生理性足印和适当的后足对线。AOFAS 平均评分为 90.4±9.2（72-100），SF-12 平均得分为 44.7，34 名患者中有 30 名（88.2%）对手术满意。
STA 联合生物可吸收植入物显示出满意的长期结果。根据数据亚组分析，女性的最佳手术年龄为 9-11.5 岁，男性为 9-13.5 岁。
