Elbow joint with dislocation

Object numberGC.3854
TitleElbow joint with dislocation
DescriptionElbow joint, Dissection of an adult left, showing a posterior congenital dislocation of the radius.
The condition was bilateral
The radial head is displaced posteriorly so that the neck is in contact with the capitulum. A portion of the articular capsule has been removed to expose part of the head of the radius which has not developed its cup-shaped character but appears to be rounded and convex. On the humerus the capitulum is modified in shape to fit an elongated cartilage covered surface on the radial neck. The shape of this surface seems to preclude pronation.
