Arthrodesis is a medical term that refers to a surgical procedure that involves fusing two or more bones together permanently. Common synonyms for this term include joint fusion, spinal fusion, bone welding, and bone grafting. These procedures are commonly used to provide stability and relief to patients experiencing chronic pain or deformity in their joints. In some cases, arthrodesis may be required due to injury or degenerative conditions that have led to significant joint damage. While arthrodesis may be considered a last resort, it can be a highly effective and life-changing treatment option for patients who have exhausted other non-surgical treatments.
