증상이 동반된 소아 유연성 편평족 치료에서의 Calcaneo-stop 술식

초록

Purpose: The aim of the current study is to report on the clinical and radiographic results after calcaneo-stop procedure in Korean children with symptomatic flexible flatfoot. Materials and Methods: Twenty-two children suffering pain along the medial aspect of midfoot with flexible flatfoot whose symptoms did not improve with conservative measures and therefore underwent calcaneo-stop procedure were identified retrospectively. Clinically, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and visual analogue scale (VAS) were evaluated. Radiographically, standing anteroposterior and lateral radiographs of the foot and Saltzman’s alignment views were taken and talonavicular coverage angle, lateral talo-first metatarsal angle, and hindfoot alignment angles were measured and analyzed. Results: Clinically, AOFAS ankle-hindfoot scale improved from 70.3±5.6 to 97.3±2.5 and VAS improved from 6.4±1.6 to 0.2±0.4. Radiographically, talonavicular coverage angle improved from 28.3o±12.3o to 10.9o±8.1o, lateral talo-first metatarsal angle improved from –19.3o±9.0o to –2.4o±8.1o, and hindfoot alignment angle improved from valgus 11.9o±10.0o to 3.5o±4.3o at minimum 2-year follow-up. No complications occurred postoperatively. Conclusion: Calcaneo-stop procedure is a simple and very effective procedure for management of pediatric symptomatic flexible flatfoot that does not respond to conservative treatment.
