Tendon transfers and reconstructive procedures for chronic ulnar palsy
Regarding tendon transfers and reconstructive procedures for chronic ulnar palsy, which of the following statements are true?
1.With time in chronic ulnar palsy the central slip stretches and the lateral bands translate volarly, fixing and worsening the claw deformity.
2.The Zancolli lasso procedure is a static tenodesis used to correct claw deformity.
3.Transfer of the extensor indicis proprius to the adductor pollicis is the standard operation for restoring thumb adduction in low ulnar nerve palsy.
4.Flexor digitorum superficialis can be used as the motor donor to restore intrinsic function — for example, the Stiles–Bunnell transfer (FDS slips routed through the lumbrical canals to the radial lateral bands) or the Zancolli lasso (FDS looped through the A1 pulley).
5.Side-to-side tenodesis between the ulnar and median FDP tendons is principally used to correct claw deformity in low ulnar palsy.
