Back pain and radiologic changes in the thoraco-lumbar spine of athletes.

Back pain and radiological changes of the thoraco-lumbar spine were investigated in 142 top athletes, representing wrestling, gymnastics, soccer and tennis (age range 14-25 years). All groups of athletes reported back pain at high frequencies (50-85%). Male gymnasts had significantly increased incidence and severity of back pain as compared to the rest of the athletes. Radiological abnormalities occurred in 36-55% of the athletes. Reduced disc height, Schmorl's nodes and change of configuration of vertebral bodies correlated with back pain (P less than 0.05, P less than 0.01 and P less than 0.05). Significant covariation between these types of abnormalities was found. Athletes with great demands on the back are thus subjected to an increased risk of symptomatic damage of the spine.
