Calcaneo-stop Procedure for Management of Pediatric Symptomatic Flexible Flatfoot / 대한족부족관절학회지

ABSTRACT

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 28.3degrees+/-12.3degrees to 10.9degrees+/-8.1degrees, lateral talo-first metatarsal angle improved from -19.3degrees+/-9.0degrees to -2.4degrees+/-8.1degrees, and hindfoot alignment angle improved from valgus 11.9degrees+/-10.0degrees to 3.5degrees+/-4.3degrees 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.
