WALANT office based endoscopic cubital tunnel release

Abstract

Cubital tunnel syndrome is a common condition caused by compression of the ulnar nerve around the medial elbow. Surgical treatment usually involves open in situ ulnar nerve decompression unless ulnar nerve instability is noted. Endoscopic techniques for cubital tunnel release have been developed and implemented with excellent patient and surgeon satisfaction. Endoscopic cubital tunnel release can be performed in an office based procedure room under wide awake local anesthesia no tourniquet principles. We present our setup and technique for performing an endoscopic cubital tunnel release procedure in an office based setting under local anesthesia. Local anesthesia is injected along the course of the ulnar nerve on the medial arm and forearm extending 10 cm proximal and distal to the medial epicondyle. After allowing approximately 30 min for appropriate vasoconstriction, the patient is placed in a supine position with the arm abducted and externally rotated position. The endoscopic cubital tunnel release is then performed. Our described technique eliminates the need for placement of a prophylactic tourniquet and thereby the need for the procedure to be performed within an OR setting. It also utilizes a single-stage anesthetic administration, which facilitates ease of completion and performance in an office based setting. There is a significant cost savings when endoscopic cubital tunnel release is performed in an office-based procedure room compared to in the operating room. Office-based endoscopic cubital tunnel release can be safely performed utilizing WALANT techniques, leading to high patient satisfaction and decreased overall cost of care. Therapeutic IV
