What term describes the process of removing an abnormal restriction in a joint, such as calcium deposits?

The process of removing an abnormal restriction in a joint, such as calcium deposits, is appropriately described by the term "arthrolysis." Arthrolysis refers to the surgical procedure aimed at freeing a joint from restrictive adhesions or abnormal deposits that may be causing stiffness or limited range of motion. This can involve the removal of calcified tissue, scar tissue, or any other material that is impeding the normal function of the joint.

Understanding the context of this procedure is crucial. Unlike arthroplasty, which involves the replacement of a joint, or arthroclasia, which specifically refers to the breaking of a joint contracture to restore movement, arthrolysis specifically targets the removal of restrictive tissue without replacing the joint itself. Bursectomy, on the other hand, is the surgical removal of a bursa, which is a different structure altogether and does not relate to the removal of restrictions in the joint itself.

Thus, the correct term for the process described in the question is arthrolysis, focusing on restoring normal joint function by alleviating abnormal restrictions.
