A synovial joint, otherwise known as a diarthrosis, is the most flexible type of joint, seeing as it achieves its range of movement at the point of contact between the articulating bones. This mechanical area forms the meeting point between the radius and ulna of the forearm with the humerus of the brachial region.It is deemed a compound joint because the joint cavity is continuous with the radioulnar joint, as well as the contact points between these bones and the humerus respectively.oints. The humeroulnar joint is the contact point of the humerus and the ulna. It has a single axis and is therefore a synovial hinge joint that simply opens and closes. The articulating surfaces can be found between the trochlea of the humerus and the trochlear notch of the ulna.
