While talking about herniated disc, we should also mention the “narrow canal” in order to eliminate some misconceptions in people. Because, contrary to what is known, “narrow canal” is a disease that can be treated, and the results obtained from surgical treatment are at least as satisfactory as those of lumbar hernia, if performed in accordance with the surgical procedure.

The spinal canal, through which the spinal cord and nerves pass, is a thin, long, curved tube composed of bones stacked on top of each other. This channel has a certain width. If this width decreases, the spinal cord and nerves passing through the canal begin to compress. As a result, symptoms such as pain, numbness, forced sitting after walking, deterioration of urine and stool control, weakness in the legs, and gait disturbance may occur. Patients with such complaints should be thoroughly investigated. Because the signs and symptoms of some diseases such as spinal tumors may mimic the narrow spinal canal. The narrow canal in the neck region also affects the arms.

If a person has a “narrow canal”, it should be kept in mind that even a small hernia to be added to it can cause great pain and the clinic can be very noisy.

Physical therapy and other non-surgical treatment methods are often unsuccessful in patients whose walking distance and standing time are markedly shortened.

If the specialist doctor deems surgery necessary, it would be beneficial not to delay it. With the surgery applied to this type of patients, the canal is widened and the pressure on the nerve elements is removed. As a result, patients feel very relieved. If there is a herniated disc, the hernia is also evacuated in the same session. If the stabilization is impaired, an intervention that strengthens and stabilizes the spine can also be performed within the same surgery. If the patient is very old or if general anesthesia is inconvenient for any reason, surgeries can be performed with spinal anesthesia.

In recent years, we routinely apply internal decompression with microtechnique, which is a new and much more promising technique in narrow canal operations
