-angulation of this joint forms the "carrying angle". The elbow joint consists of two types of articulations and thus allows two types of motion. The limited motion at hinge joints provides for more strength and reinforcement from the bones, muscles, and ligaments that make up the joint. The first is by joint function, also referred to as range of motion.The second way to categorize joints is by the material that holds the bones of the joints together; that is an organization of joints by structure.. Classification of the joints of the elbow complex: Humeroulnar joint - the joint is a hinge joint, and extension, flexion are the only motions occurring here.
