Abstract
The anatomy of the thumb flexor pulley system and surrounding structures differs from
the fingers. The hand's positioning during trigger thumb release is troublesome. Iatrogenic
radial digital nerve injuries of the thumb following opened or percutaneous A1 pulley
release have been reported. We present the radial approach using a transverse incision
for surgical release of the trigger thumb. This surgical approach aimed to restore
a familiar surgical hand position, prevent radial digital nerve injury and bowstringing
of the flexor pollicis longus, and decrease postoperative pain to facilitate recovery
of hand function.
