PROBLEM TO BE SOLVED: To provide a nonmagnetic and nonconductive fixation material usable in an MRI environment. SOLUTION: This external fixation element 1, 10 and 30 comprises antimagnetic core parts 2 and 23, and nonconductive sheath parts 3 and 33 covering essentially the core parts 2 and 32 when used in any frame configuration for the upper & lower extremities and pelvis. The rods 1, pins 30 and clamps 10 are especially MRI safe for a patient wherein the usual MRI field parameters of a static field of 2 Tesla, a time-varying field 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.
