Epidemiology of podiatric injuries in US Marine recruits undergoing basic training.

The authors determined the incidence of podiatric injuries that occurred during 233,946 recruit days at risk among US Marine Corps recruits undergoing basic training at the Marine Corps Recruit Depot, San Diego, CA, between February 5 and April 25, 1990. Training-related initial injuries to the foot occurred at a rate of 3.0 new injuries per 1,000 recruit days. The highest specific rates of injury occurred with stress fractures to the foot (0.56 per 1,000 recruit days), ankle sprains (0.53 per 1,000 recruit days), and Achilles tendinitis (0.39 per 1,000 recruit days).
