Medial column stabilization improves the early result of calcaneal lengthening in children with cerebral palsy

Calcaneal lengthening is a popular surgical treatment for pronated foot deformity. The aim of this study is to assess the effectiveness of medial column stabilization in improving the results of calcaneal lengthening for pronated foot deformity in ambulatory children with cerebral palsy. Twenty-one consecutive (37 feet) children with cerebral palsy with pronated foot deformity who received calcaneal lengthening from 2004 to 2009 were reviewed. Talonavicular stabilizations were performed by either stapling alone or fusion depending on the children’s age and correctability of midfoot deformity. Satisfaction rates were assessed using Mosca’s radiographic, Mosca’s clinical, and Yoo’s clinical criteria. Talonavicular coverage angle was also measured. Results between groups with and without stabilization of the talonavicular joint were compared. Group 1 included 11 children (19 feet) who had no talonavicular stabilization. Group 2 included 10 children (18 feet) who had talonavicular fixation. Groups were further divided into subgroups A [Gross Motor Function Classification System (GMFCS)≤II] and B (GMFCS≥III). Factors including demography, geographical classification, functional status, and preoperative degree of deformity were similar between the two groups. After the operation, all four radiographic parameters improved significantly. The talonavicular coverage angle was better in group 2 than in group 1. Mosca’s radiographic results were satisfactory in 73.68% of ca...
