- Abstract: STUDY DESIGN: The degenerative changes in plain X-ray and bone mineral density of the lumbar spine of postmenopausal women was evaluated retrospectively. OBJECTIVE : We analyzed the correlation between degenerative arthritis and osteoporosis of lumbar spine, which are common senile spinal disorders in old age. SUMMARY OF LITERATURE REVIEW: Inverse relationship has been reported between osteoporosis and osteoarthritis in the studies of hip fractures. MATERIALS AND METHODS: For 108 female patients older than 50 years of age, the degenerative change of lumbar spine was evaluated by scoring with Kellgren's classification of disc degeneration and with Nathan's classification of osteophyte from radiographs of lumbar spine. Bone mineral density of lumbar spine was measured with dual energy X-ray absorptiometry. Osteoporotic fracture of vertebral body was scored by Renier's index. The correlation between the data of degenerative changes and bone mineral density was analyzed. RESULTS: Kellgren's score of disc degeneration had positive correlation with lateral lumbar bone mineral density suggested that disc degeneration decreases osteoporosis. CONCLUSION: Osteoporosis and osteoarthritis of senile spine had an inverse relationship, and was not simply the end result of normal aging. Understanding of relationship of two disorders would be helpful in treatment decision.
