Scope-assisted release of the cubital tunnel.

We report on a technique of endoscopic release of the cubital tunnel, which is a modification of Bruno and Tsai's technique. This article covers the history, complications, indications, and postoperative management of ulnar nerve entrapments treated endoscopically, with a special focus on our technique. This minimally invasive alternative to transposition requires no mobilization of the ulnar nerve, which could potentially reduce iatrogenic trauma to the nerve and its vascularity.
