title: Stress fracture of the ulna occurring in military recruits after rifle drill training.
abstract: Stress fractures are a common injury in military recruits in the lower extremities, but are rare in the upper limbs. The locations of reported stress fractures occurring in the upper extremities are mainly in the ulna and olecranon. We report on two cases of mid-ulnar stress fractures in a team of honor guards following rifle drill training from excessive weight lifting, repetitive pronation of the forearm, and a sudden increase in the training load. According to the report, some readjustment must be made in the training protocol for military recruits. Stress fractures are also being recognized as a prevalent problem in the upper body.
