What is the term for a surgical procedure performed to immobilize a joint?

The term for a surgical procedure performed to immobilize a joint is arthrodesis. This procedure involves the surgical fusion of the bones within a joint to eliminate movement and provide stability. The goal of arthrodesis is to relieve pain in cases where other treatments have been ineffective, such as in advanced arthritis, severe joint instability, or after an injury.

Arthrodesis can be beneficial for patients as it can lead to significant pain relief and improved function in the affected area, although it does sacrifice some range of motion in the joint that is fused. The procedure can be applied to various joints in the body, including the spine, ankle, and wrist.

Other procedures mentioned do not specifically aim to immobilize a joint. Arthroscopy is a minimally invasive procedure used for diagnosing and treating joint problems. Arthroplasty refers to the surgical replacement or reconstruction of a joint, designed to restore its function rather than immobilize it. Arthritis surgery is a general term that can refer to various surgeries aimed at treating arthritis but doesn't specifically denote a procedure intended for joint immobilization.
