Looked at theoretically thismethod would appear to be a most effective means fordestroying the joint, but as a matter of fact most of the 154 cases treated in this way do marvelously well. To be sure^w^hen treated by a traction-splint of the usual pattern(Sayre, Taylor, or Judson), that does not rise above thepelvis, and, as Lovett long since pointed out, allowsabout 30° of anteroposterior motion, most of the casesrecover with flexion and adduction deformity, and with both true and false shortening, and much rigidity. Fig. 116.—Method of changing the line of pressure on the skin from the-Thomas hip-splint. When the long traction-splint is supplemented by abody-piece, as in the Ridlon and the Phelps splints,with no motion between body-piece, hip band, and ex-tension-bar, the splint becomes the most useful meansfor the correction and prevention of lateral deformity,,and is second only to the Thomas hip-splint for correc-tion and prevention of anteroposterior deformity. Trac. 155 tion, during recumbency, when combined with leverageis a most effective means for reducing deformity, and incertain sensitive cases during the development ofabscess, is a very efficient aid in allaying muscularspasm, and reducing the paroxysms of pain. In otherequally sensitive cases it is not well borne, and positivelyincreases the suffering. In the majority of cases it isneither indicated nor contraindicated. In cases thatare no longer particularly sensitive it may be used as a
