Mini-invasive surgery for chronic exertional compartment syndrome of the forearm: a new technique

Chronic exertional compartment syndrome is now easily identified among the athletic population. It remains common in motorcyclists. The only treatment is the fasciotomy of the compartments and the gold standard procedure is still the open-invasive surgery. The authors describe a new mini-invasive surgical procedure to perform a 4-compartment fasciotomy of the forearm, and expose their results. Over a 3-year period, we reviewed 16 cases of forearm compartment fasciotomy for 8 patients with bilateral chronic exertional compartment syndrome of the forearm who had been operated on. All 8 were males, with an average age of 23 years. All were competition motorcyclists, either in cross-country or speed competitions. They were all treated with the same bilateral procedure: a mini-open fasciotomy of the 4 forearm compartments using the Knifelight, which is a sharp blade between 2 plastic blunt skids originally designed for carpal tunnel release. All patients had resumed their sport in the 6 weeks after the surgery. They were back to their previous level in 3 cases, and improved their level in 5 cases. No complications and no recurrences were reported during an average 2-year follow-up. The mini-invasive technique for fasciotomy seems to be as efficient as the open technique procedure, which is still the gold standard. But the length of surgery, recovery time, and scar sequelae are much better. Mini-invasive surgery is simple, efficient, and the results are reproducible.
