arthrodesis
Pronunciation: ar-throh-DEE-sis
Surgical fusion of a joint to eliminate motion and provide stability, typically for pain relief.
Full Definition
A surgical procedure that permanently fuses two or more bones across a joint to eliminate joint motion and provide stability. Arthrodesis is indicated when joint preservation is not possible due to severe arthritis, infection, instability, or deformity. The procedure involves removing cartilage from the joint surfaces and using bone grafts and/or internal fixation to promote bone healing across the joint space. While joint motion is sacrificed, the procedure typically provides excellent pain relief and stability.
Usage
Usage note: Specify joint being fused. Distinguish from arthroplasty (joint replacement) and arthrolysis (joint mobilization).
