countertraction /-trak″shən/ [L, contra + trahere, to pull] , a force that counteracts the pull of traction, such as the force of body weight resulting from the pull of gravity. Orthopedic countertraction may be obtained by altering the angle of the body-weight force in relation to the pull of traction, such as by elevating the foot of the bed with blocks to attain the Trendelenburg position. The magnitude of countertraction is usually increased gradually by methodically changing the position of a patient and by adding or removing weights from weight hangers.
