Medial facetectomy is a spinal procedure that partially removes one or both of the facet joints on a set of vertebrae. The procedure intends to decompress the spinal nerves being pinched by degenerated facet joints. Patients requiring medial facetectomy have facet joint syndrome, which means the cartilage around their facet joints have worn down. These joints normally help with the spine's range of motion and aid the patient's ability to bend, twist, and stand up. Patients with facet joint syndrome have worn down facet joints that rub against the spinal nerves, causing pain and other debilitating symptoms.
