On the posterior aspect of thelower fragment of the humerus a kind of cup-shaped expansion isseen which articulates with the extremity of the upper fragment ; thelatter has undergone but slight alteration. The cup-shaped expansionis formed entirely by periosteal deposit, the medullary cavity is almostcompletely occluded at the extremities of both fragments, includingthe free lower extremity of the lower fragment.
