Laminotomy

Laminotomy is a neurosurgical procedure that involves the removal or trimming of a portion of the vertebral bone called the lamina. The procedure is performed to alleviate pressure on the spinal cord or spinal nerves, which can be caused by conditions such as spinal stenosis, herniated disc, or spinal tumors.

Procedure

A laminotomy is performed under general anesthesia. The surgeon makes an incision in the back over the affected area. Using specialized tools, the surgeon removes or trims a portion of the lamina to create more space for the spinal cord or nerves. The incision is then closed with sutures.

Indications

Laminotomy is indicated for conditions that cause pressure on the spinal cord or nerves. These conditions include spinal stenosis, herniated disc, and spinal tumors. Symptoms of these conditions can include back pain, sciatica, numbness or weakness in the limbs, and difficulty walking.

Risks and Complications

As with any surgical procedure, laminotomy carries risks. These can include infection, bleeding, nerve damage, and complications from anesthesia. There is also a risk that the procedure may not alleviate the symptoms.

Recovery

Recovery from a laminotomy can take several weeks. Physical therapy may be recommended to help regain strength and mobility. Pain medication may also be prescribed to manage post-operative pain.
