What type of procedure does the term "surgical fixation or fusion of joints" describe?

The term "surgical fixation or fusion of joints" specifically refers to arthrodesis. This procedure is performed to stabilize or fuse two or more bones in a joint, often to relieve pain or improve function by eliminating the movement at that joint. Arthrodesis is commonly done in conditions such as arthritis or after severe injuries to the joint where normal function cannot be restored.

Urinometry measures the volume and concentration of urine, which is unrelated to joint surgery. Osteoclasis refers to the surgical breaking of a bone to correct deformities, not to the fixation or fusion of joints. Mastopexy is a surgical procedure to lift or reshape the breasts and does not pertain to joint fixation. Therefore, the accurate terminology for the described procedure is indeed arthrodesis.
