When the nerve canal is restricted and other measures such as physiotherapy did not provide relief, the doctor will consider a surgical treatment of spinal canal stenosis. The so called microsurgical decompression relieves the spinal canal and targets the constricted spot. In this procedure, the surgeon will remove constricting tissue and bony components of the facet joint.
For this microsurgical procedure, the incision only has to be as long as the length of the constricted nerve canal. Through this incision, the microsurgical instruments are then inserted under microscopic observation. Usually, patients’ range of movement already improves a few hours after the procedure. After about 6 to 8 days, patients are allowed to leave the hospital and can begin with the recommended rehabilitation.
