Skeleton of a man with numerous osseous growths

Three quarter length, black and white photograph of a skeleton of a man, aged 39 years, which had numerous osseous growths, of various dimensions and extent. Some of these project from the bones like osseous tumours; others, passing from one part of the skeleton to another, have produced ankylosis of many of the joints. The growths, like tumours, are present on the os frontis, mastoid process, and occiput, as well as on other parts of the skeleton where muscles are inserted, as near the angle of the lower jaw, where the masseter is inserted; at the extremities of the spines of the vetrebrae; at the coronoid processes of the ulnae, in the femur at the part where the glutaeus maximus is inserted, &c. The second and more extended kinds of ossification have in general followed the course of the larger muscles, and may be seen on the right side in the course of the deltoid, joining the clavicle and the acromion of the scapula to the humerus; in the situation of the supra-spinatus, and passing from the inferior angle of the scapula to the humerus, in the situation of the teres major and latissimus dorsi. On the back, more extensive ossifications of the muscles appear which affix the scapulae on both sides to the sacrum and ilium, and to the spines of the lumbar and dorsal vertebrae. On the left scapula the ossification of the teres major has not extended quite to the humerus, but the dorsum presents a singular process or ossification, with smooth sides and a flattened overhanging margin like an auxiliary or second spine. From the pelvis, ossifications extend from the sacrum and ilium in the direction of the glutaeus maximus, and from the tumber ischii and os pubis, in the course of the biceps and triceps abductor muscles. These extend to the right femur. Ossifications of the tendinous and ligamentous parts appear to be still more common, producing ankylosis of the vertebrae, of the left elbow-joint, of the tibia and fibula to each other on both sides, of the ankle-joints, and general consolidation of the bones of the tarsi.
