Endoscopic Ulnar Nerve Release and Transposition: Single Portal Technique

Ulnar neuropathy at the elbow (cubital tunnel syndrome) is a common compressive neuropathy in the upper limb. When non-operative management has failed to sufficiently improve the condition, surgery can be undertaken to decompress the nerve with or without anterior transposition, and this can be performed via an open or endoscopic approach. This chapter describes an endoscopic technique for ulnar nerve decompression and an endoscopic-assisted minimally invasive procedure for anterior transposition of the ulnar nerve.
