ABSTRACT

Low back pain is one of the top 10 problems that lead to visiting a family doctor. It affects 85% of people at some time in their lives. Instability is defined as loss of stability of the mobile vertebral segment, so that the application of forces to this segment produces an abnormal movement with greater displacement compared to the normal column that leads to low back pain and deformity. Acute back pain occurs between 5-25%, 90% of them remit in 6 weeks and 10% become chronic. Is the most common and costly reason for work-related disability in the population under 45; in Mexico it is the seventh cause of work absenteeism. Direct medical costs in the United States have been estimated between 12.2 to 90.6 billion per year. Lumbar instability is an important cause of low back pain and is often a major factor in determining the surgical indication for vertebral fusion with decompression. Although segmental instability is often used as a synonym for degenerative spondylolisthesis, it is clear that there are many other conditions that are potentially unstable (acute trauma, surgery, spondylolysis, tumors or infections). In the present study we review the indirect findings by Magnetic Resonance degenerative lumbar instability, since it is the most accurate method for degenerative anomalies.
