Tendon transfers in the paralytic hip.

We analyzed the results of transfers of the iliopsoas or external oblique muscles performed to augment the abductor power of the hips in 149 patients with flaccid paralysis of the hips. More than 800 supplemental procedures were performed on the lower extremities of these patients. Twenty-three of the thirty-eight hips that had been subluxated or dislocated became stable in the reduced position after the transfer operation. Every hip that had been stable before the transfer remained stable, and thirty-seven patients who had been brace-dependent became brace-free. We concluded that transfers of the iliopsoas or external oblique muscles are useful adjuncts in the treatment of paralytic disorders of the hips.
