THE INTERPRETATION OF RADIOGRAPHS. 073 The enchondromata, or chontlral osteoinata, ajipear in the neighborhoodof the joints as irreguhir masses of cartilage containing calcareous matter, oras true exostoses. They are supposedly formed from l^its of cartilage left liehindin irregular epiphyseal development. They are usually multii)le and are foundin various joint regions (Fig. 251). Bone Tumors. Sarcomata are by far the connnonest bone tumors, and the distinguishingcharacteristic of many of the types can be discovered by the Fig. 256.—Osteomalacia. Marked cj-stic formation in radius with great loss of lime salt?bend of both radivis antl ulna at the wrist. (CJriginal.) Acute The myelogenous or medullary giant-celled sarcoma is jjrone to developcysts in bone, and these cysts are often filled with blood and comprise the .so-called bone aneurisms (Fig. 252). The tumors of the osteoid or periosteal spindle-celled type present them-selves in the form of smooth, often dense swellings that spring from the super-ficial surface of the bone and are intimately connected with it, although notinfrequently the old cortical outline can still l)e made out. Their radiatingappearance is often recognizable (Fig. 253). VOL. I.—43 674 AMERICAN PRACTICE OF SURGERY.
