Final answer:
Arthrodesis is a surgical procedure that involves the fixation of joints.
Step-by-step explanation:
The word that means a surgical procedure involving the fixation of joints is arthrodesis.
Arthrodesis is a surgical procedure that aims to fuse two or more bones together in order to stabilize a joint. This is typically done when there is severe damage or instability in the joint and other treatments have failed.
For example, in cases of severe arthritis in the ankle joint, arthrodesis may be performed to fuse the bones of the ankle together, eliminating the painful joint movement and providing stability.
