Calcaneal Gait in spastic Diplegia After Heel Cord Lemgthening

Abstract

Calcaneal gait or deformity can be a significant complication after heel cord lengthening. After heel cord lengthening, 20 children with spastic diplegia were evaluated by gait analysis to define calcaneal gait objectively and describe associated morbidity. Mean age was 5 years 2 months (range 2 years 7 months to 8 years 2 months), and mean length of follow-up was 5 years 8 months (range 1 years 1 month 11 year 3 months). Calcaneal gait was defined as dorsiflexion 1 SD beyond the mean in the sagittal plane for all phases of stance. Increased ankle dorsiflexion during mid-stance most accurately predicts calcaneal gait. Through gait analysis, a 30% (6 of 20) prevalence of calcaneal gait suggests that an increased incidence of calcaneal gait may be present after heel cord lengthening.
