Patent ID: 7527626

Claim:
An external fracture fixation system forming a closed loop between bone on first and second sides of the fracture comprising two electrically conductive bone pins having a metallic tip engaging bone at a first end and extending between two external clamps and the respective first and second sides of the bone, a rod element having a unitary anti-magnetic rigid metallic electrically conductive core part and a non-electrically conductive polymeric sheath part covering an exterior surface of the core part extending between the two clamps wherein the anti-magnetic core part is made of titanium or aluminum and the non-electrically conductive sheath part is made of resin material wherein said clamps are electrically conductive and each have at least two jaws having a non-electrically conductive polymeric coated surface formed thereon wherein the jaws have teeth, a length of the teeth of the jaws is smaller in length than a thickness of the insulating sheath of said rod element.
