Abstract
An external fixation system has clamps, rods and pins having anti-magnetic core parts and a non-conductive sheath part covering essentially the exterior surfaces of the core part. The rods, pins and clamps are especially MRI safe for a patient when used in any frame configuration for fractures of the upper and lower extremities and pelvis wherein the usual MRI field parameters of a static field of 2 Tesla, a time-varying filed of max. 20 Tesla/sec and a specific absorption rate (SAR) of max. 0.4 Watts/kg averaged over the whole body of the patient apply.
