OPLL of the lumbar spine have been reported less than that of the cervical spine. OPLL leads to one of the causative factors of canal stenosis, but it is low incidence that the patients develop symptoms due to OPLL. We studied clinically 8 patients who had OPLL of the lumbar spine with low back pain, lower limb pain, sensory disturbance, and/or intermittent claudication. Five cases were male and three were female with the age range from 35 to 65 years old (average, 52 years). We diagnosed clinically and radiologically 5 of them as OPLL and the other as lumbar disc herniation. To assess the symptoms due to OPLL, we attempted to compare with the former group and the latter group. In spite of their existence of OPLL, it may or may not have clinical symptoms and signs, so careful attention must be taken to observe the condition.
