Lateral hamstring transfer and gait improvement in the cerebral palsy patient.

A retrospective analysis of twenty-three spastic patients who underwent forty-three transfers of the semitendinosus muscle to the lateral intramuscular septum and of the semimembranosus muscle to the biceps is presented. Decreased knee-flexion deformity as well as improved walking function were achieved in 91 per cent. An unsatisfactory result was associated with complications of the procedure. Only one knee of the forty-three that were operated on showed late genu recurvatum. This procedure appears to be both effective and relatively free of late comlications.
