What is a Laminectomy ?
A laminectomy is a surgical procedure that removes a portion of the vertebral bone called the lamina. The back muscles are pushed aside rather than cut and the parts of the vertebra adjacent to the lamina are left intact. Recovery occurs within a few days.
What is a Laminotomy?
A Laminotomy is a procedure that instead of removing part of the lamina, it seeks to just increase the size of the opening. This also will relieve the stress on the nerve or spinal cord caused by the narrowing of the canal.
For Spinal Stenosis
Most commonly, a laminectomy is performed to treat spinal stenosis. Spinal stenosis is the single most common diagnosis that leads to spinal surgery, of which a laminectomy represents one component. The lamina of the vertebra is removed or trimmed to widen the spinal canal and create more space for the spinal nerves and thecal sac. Surgical treatment that includes a laminectomy is the most effective remedy for severe spinal stenosis.
