The purpose of this study was to evaluate clinical and radiological outcomes at skeletal maturity after a calcaneo-cuboid-cuneiform osteotomy (triple C osteotomy) for symptomatic flatfoot deformity compared with healthy young adult controls.
Nineteen patients (30 feet) who undergone a triple C osteotomy for idiopathic symptomatic flatfeet from July 2006 to April 2013 were compared with 19 controls (38 feet). Radiographic measurements at preoperative examination, 1-year postoperative follow-up, and follow-up at skeletal maturity were evaluated. Functional outcomes were assessed by using the validated visual analog scale foot and ankle (VAS-FA) and the modified American Orthopaedic Foot and Ankle Surgery (AOFAS) score.
In the triple C osteotomy group, 11 of 12 radiographic measurements were significantly improved at 1 year postoperatively and the last follow-up ( < 0.001). There was no recurrence at skeletal maturity ( > 0.05). There were no significant differences in nine of 12 radiographic measurements between the triple C osteotomy group at maturity and the control group ( > 0.05). Average VAS-FA and AOFAS scores were significantly improved at the time of skeletal maturity ( < 0.001).
Surgical correction of symptomatic flatfoot deformity in childhood resulted in favorable outcomes after the triple C osteotomy. Deformity correction was also maintained during follow-up at skeletal maturity.
本研究旨在评估跟骰骨-楔骨-骰骨（三关节）切开术（Triple C osteotomy）治疗症状性平足畸形患者在骨骼成熟后的临床和影像学结果，并与健康的年轻成年人对照组进行比较。
2006 年 7 月至 2013 年 4 月期间，19 例（30 足）特发性症状性平足畸形患者接受 Triple C osteotomy 治疗，与 19 例（38 足）健康的年轻成年人对照组进行比较。评估术前检查、术后 1 年随访和骨骼成熟时的影像学测量值。采用经验证的视觉模拟量表足部和踝关节（VAS-FA）和改良美国矫形足踝外科学会（AOFAS）评分评估功能结果。
在 Triple C osteotomy 组中，12 项影像学测量值中的 11 项在术后 1 年和最后随访时均显著改善（<0.001）。骨骼成熟时无复发（>0.05）。在骨骼成熟时，Triple C osteotomy 组与对照组的 12 项影像学测量值中有 9 项无显著差异（>0.05）。VAS-FA 和 AOFAS 评分在骨骼成熟时均显著改善（<0.001）。
儿童症状性平足畸形的手术矫正通过 Triple C osteotomy 可获得良好的结果。在骨骼成熟后的随访期间，畸形矫正也得到维持。
