This concept, which is also called listhesis or spondylolisthesis, refers to the disruption of the arrangement of the spinal column, where one bone is shifted forward or backward relative to the others. In patients with lumbar slip, there is low back pain that increases with movement; due to the development of instability because of the prevalent movement deterioration. In other words, as a cause of this illness; the slippage may be present since childhood, or it may be due to a trauma. Of course, if these patients are overweight and working hard; the situation will be worse.
The evaluation of the patient with MR alone is not sufficient. Dynamic X-ray films, which are taken while standing, and bone scintigraphy and/or computed tomography (CT) are necessary. As a result of these examinations, the degree of slip is calculated as the percentage of slip on the other vertebrae and classified as grade 1, 2, 3 or 4. By means of these methods, the bony structural problem leading to the slip can be fully understood and a treatment plan can be made. Unfortunately, the most effective treatment method in these patients is “fusion surgery” or “instrumentation” as called among the doctors.
