Both pisiforms below the two transverses (caudad). After palpation which discloses the posterior transverse the hands are placed as follows: Palpating hand rests always on the side of the spine next the operator; opposite hand crosses the spine. Both are slanted upward so that the fingers point toward the head with the axes of the hand slightly diverging above. The wrists are thus crossed in such a way as to force the forearms to be somewhat flexed on the arms and to slant away from the wrists at an obtuse angle. This with the contact _below_ the transverses, renders it impossible not to force the vertebra in an upward (superior) direction when movement is given. [Illustration: Fig. 25. Two-finger double transverse.] Movement A comparatively slow thrusting movement, which tends to spring the spine. The merit of this method lies in its comparative painlessness. Its technic is not attractive. TWO FINGER DOUBLE TRANSVERSE A movement for posterior or postero-rotary displacements from fourth to ninth Dorsal inclusive. It serves the same purpose as the Pisiform Double Transverse but is less painful and often easier of delivery. The palmar surface of the fingers, with the flesh of the patient’s back, make a compound cushion which acts as a shock-absorber. Palpation--Contact The usual downward gliding movement of left hand if standing on right or of right hand if standing on left will serve for the discovery of the vertebra listed for adjustment. The gliding hand stops with the second finger indicating the spinous process. The first finger reaches upward and outward to the assumed location of the transverse on the side nearest the adjuster; then the second finger reaches to a similar point on the other side, both fingers pointing toward patient’s head. Now the fingers are rolled a little to make sure that they are in contact with the ends of the transverse, the palmar surface of the tip of each finger being the proper contact point. The heel of the contact hand rests near, but not on, the surface of the body over the midspinal line. Supporting Hand The ulnar edge of the free hand is now placed across the tips of the two contact fingers so that it rests directly above the ends of the transverses but separated from them by the finger tips. The upper arm is then straightened and the elbow outrotated until it locks firmly so that the arm makes a straight line directly above the transverses. The body is drawn away from the shoulder girdle, pulling the head of the humerus out of its socket as far as possible to allow free play, for all force is to be given by this straight arm. Movement If the subluxation is a straight posterior the force is driven directly downward so as to be distributed equally to the two contact points. If it be a postero-rotary, most force is directed to the more prominent (posterior) transverse. Force should be delivered quickly, keeping in mind the principle of transmitted shock.
