The present invention relates to a non-invasive external fixator (10) particularly suitable for fracture fixation. In particular, the fixator of the invention comprises proximal (16) and distal (18) portions for mounting on a limb (12) either side of a fracture (14), each of the proximal and distal portions including a rigid member (32, 34) and an articulation member (40, 42) 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.
