The present invention relates to a non-invasive external fixator particularly suitable for fracture fixation. In particular, the fixator of the invention comprises proximal and distal portions for mounting on a limb either side of a fracture, each of the proximal and distal portions including a rigid member; and an articulation member connecting the proximal and distal portions, the articulation member comprising a universal joint for allowing relative movement between the proximal and distal portions, wherein the articulation member connects the rigid members.
