Endoscopic Fascia Release for Forearm Chronic Exertional Compartment Syndrome: Case Report and Surgical Technique.

BACKGROUND Chronic exertional compartment syndrome (CECS) of the forearm is traditionally treated with open compartment release requiring large incisions that can result in less than optimal esthetic results. The purpose of this study is to describe a case report of 2 professional motocross patients with forearm CECS treated endoscopically using a minimally invasive technique. METHODS Two professional motocross racers presented with a history of chronic proximal volar forearm pain when motocross riding. Other symptoms included paresthesia and weakness, which, at times, led to an inability to continue riding. Both failed conservative management. Compartment pressure measurements were performed before and after provocative exercises to confirm diagnosis of CECS. Release of both the volar and dorsal compartments was performed endoscopically through a single incision. RESULTS Symptoms resolved after surgery. The first patient resumed riding at 1 week, competing at 3 weeks, and continues to ride competitively without symptoms at 3 years postoperative. The second patient began riding at 1 week and won second place in the National Supercross finals 5 weeks after simultaneous bilateral release. CONCLUSIONS This technique is simple and effective. The cannula used protects the superficial nerves while allowing release through a small, cosmetically pleasing incision.
