Abstract: A self-contained traction device for pelvic or cervical spine traction which can be placed on an ordinary bed is disclosed. A platform with an upwardly inclined surface is used for elevating a portion of a patient's body. A strap is attached to the portion of the patient's body to which traction is to be applied, and the other end of the strap is attached to a cable which passes over a pulley attached to the far end of the platform. The far end of the cable on the other side of the pulley is attached to a weight which provides the traction force. Because the weight is directly attached through the pulley to the platform against which the patient rests, the horizontal forces exerted by the patient's body upon being pulled by the strap are cancelled by the horizontal forces applied by the weight through the pulley to the platform so that movement of the traction device across the bed is prevented without the need for restraining it to a bed frame or the like.
