Abstract
A low cost and easy to assemble external fixator for the stabilization of a bone fracture is disclosed. The assembly of the external fixator makes use of a clamp to secure a pin to a stabilization bar. The body of the clamp will have an indentation that can be placed over the stabilization bar. Each arm of the indentation will have a hole with the two holes being aligned such that a single pin can be placed through both holes across the mouth of the indentation. Once the stabilization bar is within the indentation a pin can be inserted through the two holes in the arms of the body to restrain the stabilization bar within the clamp. The clamp will have a force applicator such as a screw that will lock both the stabilization bar and pin to prevent relative motion of the stabilization bar and the pin relative to the clamp. The preferred clamp will have a retaining clasp for gripping the stabilization bar to resist the separation of the stabilization bar from the clamp.
