ro-posterior position, from the lowerdorsal to the sacrum, by using a large extension tube with compression of theabdominal contents. It is an advantage in all positions of the spine, thorax,and abdomen, to diminish the movements of the parts as much as possible.The methods of compression employed are various. If working from below,it is an easy matter to have some simple form of compressor attached to theupper aspect of the couch. An air-cushion is placed between the patientand the couch to compress the abdominal contents. When using the tubeabove the couch, the compression may be obtained by fastening stout linenbands to the couch, carrying them round the patient, and fixing on the op-posite side. A long extension tube may be attached to the tube-holder, andfixed down on the patient by a mechanical device. These are all mattersof detail which can be arranged to suit the individual worker, but whichevermethod is employed there can be no question of the great advantages ofcompression.

PLATE V.—Normal Lumbar Spine and Pelvis. a, Normal lumbar spine. b, Normal male pelvis. <. Normal female pel\ is. THE UPPER EXTREMITY 133 The Pelvis This region often requires most careful examination, for injuries, disease,or calculi. The positions are again two, antero-posterior and postero-anterior, both being useful. To get fine detail of the sacrum an extensiontube is used, and it should be pressed well down into the pelvic cavity. Thewhole pelvis, with the heads of the femora and the acetabula, can be obtainedby using a large plate behind the patient, or by placing the patient onthe anterior surface with the plate underneath, the tube being placedabove the posterior aspect of the patient. For the examination of thecoccyx a small extension tube should be used, and the tube tilted forwardinto the cavity of the pelvis, the plate being placed on the posterior aspectbeneath the patient.
