Postural and Gait Abnormalities Caused by Hip-Flexion Deformity in Spastic Cerebral Palsy

TREATMENT BY ILIOPSOAS RECESSION

¹ From El Portal del Sol School for Cerebral Palsied and Orthopaedically Handicapped Children, San Mateo

Analysis of the gait patterns of twenty-five children with spastic cerebral palsy revealed that there were three patterns: (1) hip flexion-internal rotation with flexed knees, (2) hip flexion-internal rotation with hyperextended knees, and (3) hip flexion-internal

rotation with normal knee function. Iliopsoas recession was performed on all twenty-five patients, with additional procedures done at the same time based on the preoperative analysis as follows: In the first pattern, iliopsoas recession and semitendinosus transfer or tenotomy and semimembranosus lengthening; in the second pattern, iliopsoas recession and rectus femoris release; in the third pattern, iliopsoas recession only.

After release the internal rotation of the hip gradually decreased in the majority of patients, most of the hip-flexion deformity was corrected, and the excessive lumbar

lordosis which had developed after hamstring tendon transfer or tenotomy was obviated. This combined surgical approach resulted in an improvement in walking without a compromise of function in the majority of the children.
