Through the everted lip D, there passes a screw S, which operates through a button (which revolves on a horizontal axis), and which is fastened into another button (also revolving on a horizontal pivot) in the part A. By turning this screw we can either approximate the lip D toward the part A (producing abduction), or by reversing the screw we can separate D Fig. 3 from A, and adduct. E, E, represent the screw bolts, by which the apparatus is attached to the hip band and shaft of the splint. Before the splint is applied the screw should be turned as the circumstances indicate until the direction of the shaft of the splint corresponds with the position of the limb. After adjustment, extension is applied, in the “line of the deformity,” and no attempt should be made to overcome the contraction by the use of the screw, for several days. It should then be used very gently. It is better to imitate
