The procedure of breaking an abnormally stiff joint to increase its range of motion is known as?

The procedure of breaking an abnormally stiff joint to increase its range of motion is known as arthroclasia. This term specifically refers to the intentional fracturing of a joint to restore its mobility.

Arthroclasia is derived from Greek roots meaning "joint" and "to break," which accurately represents the procedure's purpose of improving flexibility where joint stiffness has become an issue. By breaking up calcifications or scar tissue that may be limiting movement, this technique can provide relief and enhance the overall functionality of the joint.

Contrastingly, arthrolysis involves the surgical loosening or removal of structures around a joint to alleviate pain or improve movement but does not specifically entail breaking a joint. Arthroplasty refers to the surgical reconstruction or replacement of a joint, often with prosthetic components, and bursectomy is the surgical removal of a bursa, which is a fluid-filled sac that reduces friction between tissues. Each of these terms highlights different surgical interventions without the specific focus on the breaking of stiff joints that characterizes arthroclasia.
