"laminectomy"的定义和意义

What is a "laminectomy"?

A laminectomy is a surgical procedure used to relieve pressure on the spinal cord or nerves by removing part of the spinal column's bone called the lamina. This surgery is typically performed to treat conditions such as spinal stenosis, slipped discs, or spinal tumors that cause the narrowing of the spinal cord or nerves. During a laminectomy, the surgeon makes a cut in the back over the affected bone of the spinal column, removes the lamina, and may also trim or remove other structures causing pressure on the spinal cord or nerves. This procedure aims to relieve pain, numbness, or weakness in the legs or arms caused by the spinal nerve narrowing. Physical therapy and rehabilitation are often recommended after the surgery to help patients regain strength and movement.
