Injuries of theDorsal Vertebrae.—The dorsal spine may beinvolved in injuries ofthe thorax. Ribs maybe fractured and the ver-tebral column crushed,or partial dislocationmay be present. Twopositions are useful : (1)a postero-anterior, thatis, the plate on the backand the tube in front ;(2) a lateral, to showthe bodies of the verte-brae. It is often ex-tremely difficult to show fractures of the posterior parts of the spinal and displacement of the bodies may be clearly indicated. Fractureof the transverse process sometimes occurs. When there is considerabledisplacement it is possible to demonstrate the position of the Fig. 132.—Fractures of vertebral border of scapula ami three ribs(gunshot wound). Fracture of the Ribs The demonstration of fracture of the ribs is often a matter of greatdifficulty. This is particularly so when the bone is broken through and nodisplacement takes place. When there is considerable displacement thefracture shows up readily. The best positions for showing fractures of these 158 RADIOGRAPHY bones are anteroposterior and lateral. The latter is often a difficult positionin which to show a fracture, especially in stout patients. Fracture of the Clavicle (1) At the acromial end external to the trapezoid ligament, usually pro-duced by direct violence. The inner fragment retains its position unaltered,but the outer fragment is dragged down by the weight of the arm, and for-wards by the action of the muscles, so that it lies at right angles to the restof the bones.
