flexure of the knee lift up and slightly out, thus guiding the head toward the socket, 

 rotating a little if necessary (Fig. 519). 



The Indirect or Lever Method for Dorsal Luxations. Flex the leg on the 

 thigh and the thigh on the abdomen in a position of adduction. Then sweep the

knee in a small circle with external rotation, when the knee reaches the point of 

 starting bring the limb down straight. Allis cautions against describing too large 

 a circle with the knee on account of the liability of catching up the sciatic nerve. 



FIG. 520. Reduction of a posterior (high) dorsal luxation by the indirect (lever) method of circumduction. 

 The thigh is flexed and adducted ; the knee describes the circle shown by the dotted line while the head pursues 

 the course shown in the smaller cut to the right. 



While rotating the thigh a lifting force may be added, as in the direct method. This 

 method is practically circumduction (Fig. 520). 



The Indirect or Lever Method for Thyroid Luxations. -Slightly flex the thigh, 

 about to half a right angle, and rotate outward. Slightly abduct or adduct if nec- 

 essary to relax the capsule before rotating outward.
