Retrospective review of L3 myelomeningocele in three age groups: should posterolateral iliopsoas transfer still be indicated to stabilize the hip?
The data from 58 hips in 29 myelodysplastic children with L3 paralysis has been reviewed retrospectively. Posterolateral transfer of the iliopsoas (Sharrard technique) was performed on all hips to correct muscle imbalance between 1975 and 1992. The average length of follow-up was 21 years. Preoperatively, 58.6% of the hips were either subluxated or dislocated (these were surgically reduced at the same stage). Radiological assessment revealed that 91.4% of the hips were stable at preschool age and 84.5% in adolescence. Of the patients 86% were functional walkers at preschool age and 75.8% in adolescence. Downward transitions in seven patients were related to the presence of scoliosis, spasticity and obesity. All patients who were community walkers in adolescence maintained their function in adult life at the time of the review. We conclude that the procedure has value in obtaining hip stability and walking ability in carefully selected patients with myelomeningocele.
