One method of widening a narrowed spinal canal is through laminectomy. This procedure consists in cutting out the vertebral arch plates together with the spinous process limiting the canal space from the back side. In a hemilaminectomy, the surgeon cuts the arch lamina on one side of the spinous process (right or left). If necessary, bone growths are removed and the intervertebral holes are deepened. The treatment allows you to decompress the pressed nerve roots or the spinal cord and relieve pain.

After a laminectomy (excision of the vertebral arches), getting up and walking is possible within a few days of the operation. The doctor makes the decision about the possibility of standing upright. Sometimes it is necessary to use a corset that stabilizes the operated section of the spine. Getting up and walking is done under the supervision of a physiotherapist.
