A treatise on orthopedic surgery . Weight extension acting as leverage in tiip disease. P, pulley; W, weight;F, fulcrum. (Howard Marsh.) may be raised to increase the friction of the body and thus tocounteract the traction force, but in the treatment of childrenthis is inefficient and countertraction must be provided. A simplemethod is to attach two perineal bands, as described in connec-tion with the traction brace, to strong tapes that pass above andbelow the patients body, to be fixed to the head of the bed at asuitable distance from one another; thus the pelvis is supportedby prolonged perineal bands. In order to assure eflicient and constant traction the patientmust be prevented from sitting up. For this purpose a swatheabout the body or shoulder straj)s may be applied and attachedto the bed. A convenient appliance is that of Marsh: This consists ofa piece of webbing, passing across the front of the chest and Fig. Posture of the limb in hip disease in which traction should be applied in orderto avoid leverage.

When this is in action the patients shoulders are 350 OBTHOPEDIC SUSGEEY. kept flat on the bed, so that he can neither sit up nor turn on hisside.
