The distal hitch on the STS-C is applied just proximal to the calf or patella. Coarse positioning is accomplished using a spring button to extend and lock the outer tube. Fine traction is accomplished by pulling on the cord, followed by locking with a downward pull into the V-notch. As all of the traction is controlled at the hip, it is easy to make adjustments as conditions change, or en route to the hospital.
