Abstract
Due to the increased interest in physical fitness and to the fact that athletes start their training at younger ages the risk for injuries to the growing individual has increased. The spine, as with the rest of the skeleton, is at greater risk of injury during growth, especially during the adolescent growth spurt. Back pain is more common among athletes participating in sports with high demands on the back than other athletes and nonathletes. Disc degeneration, defined as disc height reduction on conventional radiographs and reduced disc signal intensity on MRI, has been found in a higher frequency among wrestlers and gymnasts than nonathletes. Abnormalities of the vertebral bodies including abnormal configuration, Schmorl's nodes and apophyseal changes are common among athletes. These abnormalities are similar to those found in Scheuermann's disease. Athletes with these types of abnormalities have more back pain than those without. Spondylolysis has been found in higher frequencies than expected among athletes representing many different sports. Spondylolysis has been reported in up to 50% of athletes with back pain. Scoliosis has been found in up to 80% of athletes with an asymmetric load on the trunk and shoulders, such as javelin throwers and tennis players. The scoliosis, however, is a small curvature and does not cause back pain.
