Final answer:
Closed reduction is the procedure of manually breaking adhesions in an ankylosed joint to restore mobility, and it is conducted without surgery. For irreparable joints, replacement with artificial joints made of materials like stainless steel or titanium may be necessary.
Step-by-step explanation:
The artificial breaking of adhesions of an ankylosed joint is known as a closed reduction. This procedure involves the manual manipulation of a joint to restore its natural movement without the need for surgery. In the context of joint care, when a joint becomes ankylosed, its normal movement is restricted due to the formation of fibrous or bony adhesions. Closed reduction aims to remove these obstructions and allow the joint to move freely again.
In the case of damaged or arthritic joints where closed reduction is not viable, a joint replacement may be considered. Artificial joints are made from materials with low coefficients of friction, such as stainless steel, titanium, or polyethylene, allowing for smooth movement similar to a joint's natural, glassy surface that produces synovial fluid.
