Femoral anteversion and neck-shaft angle in children with cerebral palsy

A database of femoral anteversion and neck-shaft angle was compiled of meas urements made by the trigonometric fluoroscopic method of 147 patients (267 hips) with cerebral palsy. The angles of femoral anteversion were similar at early ages between healthy children and children with cerebral palsy, Ho wever, as the age of the children increased, those with cerebral palsy show ed Little change in anteversion angle, whereas the healthy children had pro gressively decreasing angles of femoral anteversion as they approached adul thood, The neck-shaft angle was increased significantly in children with ce rebral palsy compared with the angles of healthy children, Patients who wer e ambulatory were shown to have an increased angle of femoral anteversion a nd a decreased neck-shaft angle compared with nonambulatory patients, There was no significant difference in angles among the various distributions of involvement, including patients with diplegia, hemiplegia, and quadriplegi a.
