Lumbar spinal stenosis surgery, how to do it? 【 Lumbar spinal stenosis 】

Surgical treatment of lumbar spinal stenosis should first identify the specific site of stenosis. Simple nerve root canal stenosis and spinal canal stenosis, as well as multi-stage and single-stage lumbar spinal canal stenosis, have different surgical treatment methods, including:

1, fenestration decompression surgery: one or both nerve root canals are narrow, and fenestration surgery is used to decompress the nerve canals;

2. Fusion surgery: If the patient's lumbar spine is unstable according to the preoperative dynamic radiograph, it is recommended to perform intervertebral fusion and pedicle screw internal fixation.

Surgical risk:

1. Common complications caused by operation, such as wound infection, wound nonunion or delayed union.

2. Surgery leads to nerve injury, such as cauda equina nerve injury, which leads to numbness and discomfort in the saddle area, or blood vessels are damaged during surgery, which leads to vascular bleeding and neurological symptoms. These injuries can also lead to neurological dysfunction.

3. Relaxation of internal fixation after operation leads to displacement and fracture of internal fixation, which leads to recurrence or even further aggravation of symptoms.

4. The symptoms of lumbar spinal stenosis were not completely decompressed during the operation, resulting in no obvious improvement after the operation, or the symptoms recurred due to the regrowth of surrounding tissues after the operation.

5. Possibility of organ damage by surgery. The operation of lumbar spinal stenosis is performed with or without posterior incision, but it is possible to enter the abdominal cavity and damage the abdominal organs due to excessive entry.
