Arthrodesis

An operation that removes the worn joint surfaces and holds the two bones still until they grow together into one, so the joint no longer moves. Its aim is to reduce pain and give a stable joint when other treatment has not helped. Movement at that joint is lost permanently, and the bones do not always join.
