Aresort to a mutilating operation maybecome necessary if a fracture occursat the place where the bone has becomepartially destroyed by the tumor. Joints.—Floating or loose cartilages are found most frequently inthe knee- and elbow-joints. They are in the majority of cases sub-synovial chondromata which are formed at the margin of the articularcartilage, project into the joint, become pedunculated, and finally aredetached, changing their position in the joint with the movements ofthe joint. A less frequent source of such loose fragments of cartilagein joints is the detachment of fragments of the articular cartilage bya trauma. The ecchondroses of the articular cartilage exhibit under the.

They vary in size from a pea to double the size of thepatella. In many instances the articular ecchondroses are removed 1532 loose cartilages from the shoulder-joint of a presence of the foreign movable body usually produces hydropsof the joint. Impaction of the cartilage between the articular surfacesis attended by sudden pain and fixation of the joint—symptoms whichcontinue until the cartilage becomes displaced to a part of the jointwhere its presence is less harmful. The most characteristic symptoms of a loose cartilage in a joint areattacks of sudden pain and arrest of function of the joint when thecartilage gets between the opposed surfaces of the joint, followed, as arule, by more or less
