Each bone forming our spine, which is the main carrier of our body, is called a vertebra. These bones are arranged on top of each other in a certain order. There are 5 vertebrae in our waist. When viewed from the front, these bones are arranged in a straight row, and they are arranged in a semi-circle from the side.
For various reasons, small cracks called stress fractures may occur in the vertebrae in our lower back. Since these cracks are constantly moving and exposed to loads, they do not undergo a healing process like the bones in other parts of our body. Over time, failure occurs in these vertebrae, which is called spondylolysis. In spondylolysis, our spine is more mobile than normal. That is, the stability of our spine is impaired. The disease, which occurs as a result of the displacement of this unstable vertebra on the other vertebra, is called “Luminary Slipping” or “Spondylolisthesis” in medical terminology. Waist slippage occurs mostly at the lower levels of our waist, close to the coccyx.
These stretch marks on our waist do not usually cause a complaint. In lumbar slippage, the normal structure of our spine, which is arranged like rosary beads, is disrupted and it causes pressure by narrowing the spinal canal that passes through it. In this way, our spinal cord and the nerves coming out of it are compressed. The person develops back pain, numbness, tingling and weakness in the legs. The pain in our legs increases with walking, and the pain is relieved with rest. Walking with a limp is actually an indication that the “lumbar narrow canal”, that is, the spinal canal in our waist, is narrow.
Lumbar slippage can occur as a result of a blow to the person or congenital, but more often as a result of wear and tear of the spine due to aging. The person’s osteoporosis, weight, weak back muscles are among the factors that facilitate waist slippage.
When a person consults a doctor with these symptoms, first of all, a detailed medical history and examination is performed. After reflex and nerve examination, radiological examinations are evaluated. Among these, the first examination to be requested is x-ray (X-Ray). Here, our waist is examined with films taken from the front and sides and it is determined whether there is any alignment defect. Again, computed tomography (CT) to be taken allows us to evaluate the bone structures in our waist in detail. Magnetic resonance (MR) examines the spinal canal in our spine and the nerves coming out of it in detail, and it is determined whether there is any canal stenosis or nerve compression.
