Calcaneal lengthening osteotomy and extra-articular arthrodesis of the subtalar joint are two methods used for correction valgus deformity heel forefoot abduction. The purpose this study was to compare operative results these procedures in patients with cerebral palsy who were able walk. We focused primarily on changes radiographic parameters how altered mobility by would modify pressure distribution over plantar surface foot.A total eighty-one feet forty-seven included study. mean age at time surgery eight years one month, follow-up period thirty-nine months. subjects divided into groups; Group I consisted thirty-seven twenty-two underwent a calcaneal osteotomy, II comprised forty-four twenty-five an arthrodesis. Preoperative final radiographs dynamic pedobarographs evaluate results.The both groups found be similarly deformed before surgery, measurements foot-pressure analysis. Both led improved indices; however, pitch failed improve after After relative vertical impulse decreased hallux, first metatarsal head, medial aspect midfoot groups, while it increased lateral calcaneus. On other hand, postoperatively, higher through fourth heads lower group that had compared normal control subjects.Extra-articular appears effective means achieve predictable severe walk; supination remains equinus is not corrected. we believe treatment choice because postoperative more closely approximates distribution.
