Surgery is an effective method of treating thoracic spinal stenosis, so what exactly is the content of thoracic spinal surgery? 1, the core of thoracic spinal stenosis surgery is “decompression”, which literally means to reduce the pressure on the spinal cord, but in fact is the process of removing the compressor or moving the compressor away from the spinal cord, for example, for the compression of the dorsal side of the spinal cord caused by ossification of the ligamentum flavum, it is necessary to remove the corresponding segment of the thoracic spinal plate together with the ossified ligamentum flavum, so that the posterior side of the spinal cord is completely relaxed. If we can confirm that the stenotic phase is relatively straight, we can simply remove the posterior lamina if the spinal cord can be shifted backward to avoid the ventral compression. Another common component of surgery is the “fusion” of the intervertebral joint instability, usually based on decompression with nail fixation of the corresponding segment plus bone graft fusion, which eventually allows the vertebrae within the fixed fusion to grow into a continuous whole, and the segmental instability is permanently resolved. Doctor’s note: Thoracic spinal stenosis surgery does not directly treat any lesions within the bone marrow and avoids contact with the spinal cord as much as possible to reduce mechanical irritation to the spinal cord during decompression. The result of the surgery is that the spinal cord is “rescued” and no longer under pressure, but the injuries caused by the long-term pressure need to heal slowly.
