Biomechanics of Lumbar Spine Instability
Low back pain is the most common and costly disorder of the musculoskeletal system. The magnitude of the problem is well documented by the frequency of its occurrence. In western society, 50%–70% of the population will have low back pain once in their lifetime, and 18% of the population has low back pain at any one time. The cost of this disease for the United States has been estimated at $15–50 billion per year. Although the cause of most low back pain is not known, spinal instability is considered as one of the most important causes .
