    In those cases in which anchylosis does not take place there may be motion in the direction of far- ther flexion, but extension beyond a certain point is impossible; and, although the thigh can be brought down so that the foot can be planted flat on the ground, it is not from further extension, but is ac- complished by bending inward of the lumber spine, due to the same shortening of the muscles inserted into the trochanter minor. In this class of cases walking is almost as difficult as in those where the joint is fixed. In cases where suppuration has been extensive the soft parts about the region of the hip joint are often infiltrated with cicatricial tissue which binds the skin to the bone. In anchylosis following rheumatic inflammation the condition of the parts is entirely different; the head and neck are intact, the bone is not infiltrated with inflammatory products of low vitality. It may be increased in hardness, but the parts retain their normal relations, the neck is not shortened, the an- chylosis is usually bony, the soft parts are normal, and the psoas and iliacus are not as much of an ele- ment in causing the deformity. It is clue more to position, while in hip-joint disease it is the active contraction of the muscles that causes the deformity. In this disease the limb may be fixed in a straight line with the body, a condition very seldom, if ever, met with after coxalgia. In rheumatoid arthritis the joint may be sur- rounded by irregular bony growth, while the bone itself is very compact and hard, like ivory. Deformities due to unreduced dislocations are not
