<p>A flexible, light-weight, simple, modular-design Polyaxial External Fixator (PEF) for fixating bones which is strong enough to hold the bones in their intended position. The fixator uses two or more preloaded pins or K-wires or non-preloaded screws. The PEF uses non-linear K-wires anchorage using external loading cages mounted in each arm of a polyaxial hinged external fixator. The hinges and the cages offer high degree of configuration flexibility and modularity. The PEF may be provided in a kit of interchangeable parts. Most of the PEF parts are typically made of non-metallic radiolucent materials or made of any kind of metallic materials. Insertion and removal of K-wires is safe, fast and simple compare to screws.</p> |
