Radiological findings in the lumbar spine of 39 young cross-country skiers with low back pain.

The lumbar spines of 39 active young cross-country skiers suffering from long lasting or frequently remitting low back pain (LBP) were examined by a new radiological method. Plain radiographs in lateral and anteroposterior views were taken. The spinal curves, anomalies, and possible degenerative changes were investigated. The radiological method chosen proved to be suitable for imaging the lumbar spine. There were various radiologically detectable abnormalities in the spine. The most common findings were functional scoliosis (in 49%) and different spinal anomalies (in 23%). The mean lumbar lordosis was 69 degrees (70 degrees in males and 64 degrees in females). The effect of abnormal lumbar posture on LBP should be further studied. None of the numerous radiological findings had an effect on therapy in these skiers.
