Relation between the low back pain syndrome and x-ray findings. 3. Spina bifida occulta

The relation between LBP and SBO was studied in 1244 subjects, of which 800 had LBP and 444 served as controls. Sex, age, occupational characteristics, spine curvatures, spinal movements and work history were compared. It is concluded that SBO does not play a causative role, does not cause a proneness to LBP and does not influence the chronicity of LBP. Some data seem to indicate that the severity of LBP may be increased by SBO.
