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.
