arthrodesis
Pronunciation: ar-throh-DEE-sis
Surgical fusion of a joint, commonly performed in spinal surgery to eliminate motion between vertebrae.
Full Definition
Arthrodesis is a surgical procedure that permanently fuses a joint by eliminating the joint space and promoting bone healing across the joint surfaces. In spinal surgery, arthrodesis (spinal fusion) is performed to treat various conditions including instability, deformity, degenerative disease, and trauma. The procedure involves placing bone graft material between vertebrae and often using internal fixation devices such as rods, screws, and plates to maintain proper alignment during the healing process. Successful arthrodesis results in a solid bony bridge between the fused segments, eliminating motion at that level.
