The Triceps Traction Test: A Decision Tool for the Choice of Stabilizing Flap After In Situ Decompression of the Ulnar Nerve
2019
PURPOSE: Recent evidence demonstrates that in situ decompression has comparable outcomes to other surgical techniques for cubital tunnel syndrome. However, this technique does not address the instability of the ulnar nerve, a common indication to transpose the ulnar nerve. Transposition of the ulnar nerve can potentially devascularize the ulnar nerve, stabilizing flaps block subluxation of the ulnar nerve and thereby negate the need for transposition. Flaps originating from the triceps and the flexor-pronator fascia could be used to stabilize the ulnar nerve. Herein, we present a novel intraoperative test, the "triceps traction test" and our algorithm for choosing a stabilizing flap when ulnar nerve instability is encountered after in situ decompression.
