 | Laminotomy |
What is laminotomy?
Laminotomy is a surgical procedure which involves the neurosurgeon removing a portion of the lamina and ligaments. The lamina is the thin protective layer on the back of the vertebrae. The removal of a portion of the lamina helps create more space and relieve pressure on the nerves or spinal cord. This may cause pain, weakness or numbness in the arms or legs, and balance difficulties.
When is laminotomy needed?
A laminotomy may be recommended to treat back pain and pain, which may radiate down to the legs or arms. This may be caused by several conditions, such as:
- Degenerative disc disease
- Spinal stenosis
- Ankylosing spondylitis
- Herniated disc
- Arthritis
What does laminotomy entail?
A laminotomy procedure is done under general anaesthesia. During the procedure, the neurosurgeon will make an incision on your lower back. This will then give him access to the lamina, and the affected lamina will then be removed. The discs above and below the affected discs may also be removed. The neurosurgeon may use one of the following methods:
- Microlaminotomy: This is a minimally invasive procedure that involves the neurosurgeon using a thin tube that consists of a light and a camera attached to it, called an arthroscope. He will pass the arthroscope and surgical instruments through an incision on your back, where he will then perform the procedure. The recovery for a microlaminotmy is faster and has less pain.
- Open surgery: During this procedure, the neurosurgeon will make a large incision on your back over the damaged or injured vertebrae. The length of the incision depends on how many vertebrae need to be treated. Open surgery is more effective and safer, and recovery is longer.
After the nerve is free, the incision will be stitched or stapled closed. A spinal fusion procedure may also be performed alongside a laminotomy.
