Endoscopic and Endoscopically Assisted Anterior Transposition of Ulnar Nerve

Abstract

Cubital tunnel syndrome is the second most common compression neuropathy of the upper limb. It refers to ulnar nerve compressive neuropathy and most commonly occurs at the level of the elbow. Surgical options include in-situ decompression, decompression with anterior transposition of the ulnar nerve, and medial epicondylec- tomy. For anterior transposition, a longer wound is needed in order to mobilize the nerve and visualize the bed to be transposed. With the advancement of endoscopic surgery, techniques of endoscopically assisted anterior transposition and endoscopic anterior transposition of the ulnar nerve have been reported with the advantage of minimally invasive surgery. The technical details of the endoscopic approaches will be discussed in this chapter.
