    This last movement brings the normal hip-joint and the new joint into the same vertical transverse plane, and as the latter allows of no vertical play of the bones on one another the superjacent weight is safely and securely transmitted to the femur of the shorter limb. Compensation for shortening produces a rotation of the pelvis around an antero-posterior axis so as to render it symmetrical, or, more commonly, there is also a slight amount of rotation of the pelvis around a transverse axis in a direction the reverse of that which takes place after compensation, for shortening is made with a joint on the dorsum ilii, and the lumbar, 1 umbo-sacral, and sacro-iliac joints are slightly flexed. The only discomfort from which such a patient suffers is the inability to move the thigh upon the pelvis with any great freedom; but this is a small trouble as compared to the mechanical disability of the patient who has a loose and insecure joint behind and above the acetabulum, such as exists in one variety of congenital dorsal dislocation of the hip-joint, in many cases of Acquired dorsal dislocation, and in some forms of dorsal dislocation resulting from disease of the hip-joint. Any attempt to compensate for the shortening in the latter deformity increases the amount of what is called “ lordosis/5 which I have shown you is an over-extension of the lumbar, lumbo-sacral, and sacro-iliac joints, a position of gTeat insecurity and mechanical disability. This occurs because the dorsal joint is situated behind the transverse axis of pelvic rotation, and in consequence the pelvis cannot be made to rotate satisfactorily around an antero¬ posterior axis.
