摘要：A 90/90 traction device having a bed with an overhead traction frame, from which is suspended, by cables, a horizontal traction board for supporting the calves of the legs in a horizontal position above the bed. Leg bands connected to weighted cables passing over pulleys at the foot of the bed apply traction to the vertically disposed thighs of the legs. The board is provided with resilient material over the front and top, so as to prevent loss of circulation in the legs and is provided with arresting cables attached to the head of the bed to prevent movement of the board toward the foot of the bed. The various cables are adjustable in length.
