Overview

Spinal decompression surgery is a type of neurosurgery that relieves pressure on the spinal cord or spinal nerves. Herniated discs, spinal stenosis, bone spurs, tumours, or thickened ligaments can all cause nerve compression. When nerves are compressed, patients may feel back or neck pain, numbness, weakness, or difficulty walking. Decompression can be done in a number of ways, such as laminectomy (removing part of the vertebral bone), discectomy (removing a herniated disc portion), and foraminotomy (widening nerve passageways). In some cases, spinal fusion is done along with decompression to keep the spine stable. The main goal is to ease pain and restore nerve function.

Why It’s Done
When medications, physical therapy, or injections don't work to relieve symptoms, spinal decompression surgery is done. It is recommended for nerve compression that doesn't go away and causes severe pain, weakness that gets worse over time, loss of coordination, or problems with the bladder and bowel. In emergencies like spinal cord compression, surgery needs to be done right away to avoid permanent damage to the nervous system. The goal is to relieve pressure on the affected nerves, making it easier to move and live a better life.

What to Expect?
Before surgery, imaging tests like MRI or CT scans are performed to determine where the nerve compression is and what caused it. A general health check and blood tests are part of the preoperative evaluation. General anaesthesia is given during the procedure. The surgeon cuts into the spine in the area that is hurting. Depending on the condition, a portion of the bone, a thickened ligament, or damaged disc material is carefully removed to make more room for the nerves. If there is instability, spinal fusion with screws, rods, or bone grafts may be done. The patient is monitored in a recovery unit after surgery and may remain in the hospital for a few days. Pain management, early movement, and physical therapy are all important parts of post-surgery care. Under a doctor's guidance, it is advised to gradually increase activity.

Recovery & Outlook
The time it takes to recover depends on how much surgery was performed and the person's overall health. A lot of people feel a lot better after getting treatment for leg pain and nerve problems. During healing, it is normal to feel sore or stiff for a short time. Physical therapy helps you regain your strength and flexibility. When nerve damage hasn't lasted for a long time, the long-term outlook is usually good. Early intervention increases the likelihood of complete neurological recovery and improved daily functioning.
