ABSTRACT:
Traction across a joint of the body is provided by the hinged external fixator which holds bony parts by means of screws or pins embedded in the bony parts. The hinged external fixator permits portable traction allowing early mobilization, wound care, and flexing and exercise of the articular cartilage to promote healing and to prevent post traumatic arthritis. An adjustable distension apparatus, having an integral spring biased force garage, provides conveniently alterable and measurable traction forces.
