Lumbar decompression surgery is performed to relieve pressure on the lumbar spine nerves, often caused by conditions such as herniated discs, spinal stenosis, or degenerative disc disease. The procedure involves removing or trimming the parts of the spine that are compressing the nerves, thereby alleviating pain, numbness, and weakness in the lower back and legs. Lumbar decompression is carried out by experienced neurosurgeons or orthopedic surgeons, aiming to restore spinal function and improve the patient’s quality of life.
