TRACTION DEVICE ABSTRACT OF THE DISCLOSURE An orthopedic traction device which consists of a frame having upstanding arms attached to a base member portion, upon which a patient may recline. The upstanding arm framework has a transverse bar portion connecting two upstanding arms, and a lever arm member pivotally mounted at an intermediate point of the transverse bar, the lever arm having calibrated graduations. A calibrated weight is slidably mounted on the graduated lever arm. There is a movable limit collar having a locking screw for posi- tion. A cable is connected to the end of the lever arm member. Tension force is transmitted to the patient from the lever arm through a cable and pulley system connected to a head harness. Tension force is transmitted to the spinal column and may be reacted by shoulder pads mounted on extensible arms pivotally mounted on the frame, if the traction is desired to be limited to the cervix. The head harness receives the load from the cable through a spring-like member which yields to allow the head harness to provide a gripping action over the whole cheeks of the face, thereby reducing high stress areas, such as on the chin. The device may be modified with reaction braces and harnesses to apply calibrated tensile load to other portions of the anatomy. In addition, a motor-driven device may be provided to alternately relieve and apply the load on the patient. A secondary vibratory force may be applied through the cable to give a high or low fre- quency of vibration to the portion of the anatomy under tensile traction load to further enhance the effect of the treatment.
