DescriptionA right elbow joint, showing a congenital dislocation of the radius.
The proximal head of the radius is small and has been posteriorly displaced. The shafts of both the ulna and radius are altered, with curvature of the proximal shaft of the ulna, and flattening of the shaft of the radius. Such changes may indicate underlying rickets in this individual.

TranscriptThe lower end of a right humerus, with the radius and ulna, showing a congenital dislocation backwards of the head of the radius. The head of the radius is small; it lies below the external condylar process in the flexed position of the joint and its anterior part and the adjacent part of the neck articulates with the lesser sigmoid cavity of the ulna. The upper surface of the olecranon and the head of the radius are almost at the same level and the styloid process of the radius is on a level with that of the ulna. The ulna articulates in the normal way with the humerus, except that the articular surface is expanded laterally and rests partly against the capitellum. The shafts of both radius and ulna are altered in shape; the upper part of the ulna is unduly curved and anteriorly presents a sharp crest; the shaft of the radius is flattened.

TranscriptThe bones composing the elbow-joint, showing a luxation of the radius. The form of both the ulna and radius is altered, to adapt them to each other in their new relative situations.
