Evaluation of rotational gait abnormality in the patients cerebral palsy.
Internal rotation of hip is commonly seen in children with cerebral palsy. Existing muscle imbalance causes persistence of femoral deformity, which may contribute to rotational asymmetry. In cerebral palsy, gait deviations are the result of dynamic and static components, both caused by muscle imbalance. In this study we investigated the predictability of hip rotation in gait from the measurement of anatomic deformity. Computed tomography (CT) measurements of femoral anteversion and physical examination data failed to predict the hip rotation in gait. However, tibial (CT) measurements and physical examination data highly correlated with tibial rotation in gait. We conclude the dynamic component of hip rotation during gait is significant, as anatomic deformity did not predict gait deviations.
