Advantages and Risks of Endoscopic Anterior Subcutaneous Transposition of the Ulnar Nerve

Advantages	Risks
Smaller wound	Medial antebrachial cutaneous nerve can be damaged at the skin incisions.
Requires little soft-tissue dissection	Injury to the branch that innervates the flexor carpi ulnaris
Better arthroscopic visualization	Injury to the ulnar nerve
Causes less vascular insult to the nerve	Injury to the brachial artery and median nerve
Faster recovery for the patient	Inadequate release of the ulnar nerve
	Inadequate mobilization of the ulnar nerve
