How the US Army Forged Hand Surgery.

As the United States plunged into World War II, the surgeon general, Norman T. Kirk, scrambled to care for the complex hand injuries sustained in combat. To remedy this problem, Major General Kirk appointed Sterling Bunnell, a general surgeon and a World War I veteran with a keen interest in hand injuries, to serve as the consultant to the Secretary of War. Kirk and Bunnell formed 9 US military hand centers that treated 22,000 hand injuries in World War II. Bunnell and his pupils would later form the nucleus of the American Society for Surgery of the Hand. Through Dr. Bunnell's expertise, skillful care, dedication to teaching, and love of country, US hand surgery was born.

Anatomy of the anterior interosseous innervation of the pronator quadratus: evaluation of structures at risk in the single dorsal incision wrist denervation technique.

PURPOSE: Patients with chronic wrist pain often are treated with wrist denervation, which typically involves transecting both the anterior interosseous nerve (AIN) and the posterior interosseous nerve. A single dorsal incision approach is an improvement over the more traditional multiple-incision technique. The purpose of our study was to describe the branches of the AIN to the pronator quadratus and evaluate the risk of denervation with the single dorsal incision technique. METHODS: Twelve fresh-frozen cadaver forearms were dissected. The branches of the AIN to the pronator quadratus were identified and the individual branch points were measured from the articular edge of the distal radius. Wrist denervation was then performed on each specimen through the single dorsal incision (as suggested by Berger). RESULTS: There were an average of 3 branches from the AIN to the pronator quadratus. All forearms had at least 1 branch to the pronator quadratus more proximal to the distal end of the dorsal skin incision; however, in only 2 of the forearms was the most proximal branch more than 2 cm proximal to the distal end of the dorsal skin incision. CONCLUSIONS: Wrist denervation through the recommended single dorsal incision poses a serious risk for completely denervating the pronator quadratus. Therefore the resection of the AIN must be performed close to the distal margin of the pronator quadratus.
