The coronoid process rests in that fossa ofthe humerus which naturally contains the olecranon. (2.) In dislocation of both hones backwards and outwards, the coronoidprocess is thrown behind the external condyle; and in addition to thepreceding symptoms, the head of the radius can be very plainly felt onthe outer side of the joint. (3.) The dislocation backwards and inwards is known by a greatprojection of the outer condyle, in addition to the symptoms of the firstvariety. (4.) In dislocation backwards of the ulna solely, the olecranon is muchprojected backwards;—the elbow is immovably bent at right angles, andthe forearm is much twisted and pronated. Fig, 72. Fig.
