Abstract
Abstract This invention is a traction splint including a tension applying mechanism with an outer knob to apply tension to a tension stirrup through belting wound about a shaft while such tension is released by turning of an inner knob in the opposite direction. Both of these knobs are uni-directional relative to rotative movement but in opposite directions. A folding support leg and relatively simple and yet extremely efficient bindings and appendage supports are also included features.
