Wrist denervation of the posterior interosseous nerve through a volar approach: a new technique with anatomical considerations.

Purpose: Full or selective wrist denervation is an effective treatment for chronic wrist pain. In this cadaveric study, a volar approach for prophylactic denervation of the posterior interosseous nerve (PIN) and the anterior interosseous nerve (AIN) was assessed, which can simultaneously be performed during volar approaches for distal radius fracture fixation or in combination with metalwork removal.

Materials And Methods: In total 40 adult upper limbs, embalmed using Thiel's method, were investigated.
