What is foramenotomy?

Foramenotomy is a surgical procedure aimed at enlarging the intervertebral foramina, which are the openings through which spinal nerves exit the spinal canal. By removing the roof of these foramina, foramenotomy creates more space for the nerves and can relieve compression or irritation that may lead to pain, numbness, or weakness in the patient's limbs. This procedure is often performed to address conditions such as foraminal stenosis, where the space around the nerve roots is narrowed, potentially causing discomfort or neurological symptoms.

The focus here is on the removal of bone or other tissue to alleviate pressure around the nerve, which is crucial for ensuring proper nerve function and reducing symptoms associated with nerve compression. Understanding the purpose and specific action of foramenotomy helps clarify its role in spinal surgery and the treatment of related conditions.
