Patent ID: 8827998

Claim:
A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements, said fixation clamp comprising at least one clamping assembly, and at least one locking element extending through the at least one clamping assembly for blocking the position of the at least one clamping assembly in a defined angular position; wherein said clamping assembly comprising a first jaw having a contact surface and at least one groove; a second jaw having a contact surface and at least one groove, the second jaw contact surface is in contact with the contact surface of the first jaw; at least one reception provided by means of said grooves to accommodate a fixation element along a longitudinal axis of the reception; at least two orientation devices that extend from and/or into said contact surfaces, the at least two orientation devices are adapted to orient the first jaw with respect to the second jaw, wherein the orientation device comprises an elongate recess extending from one of said contact surfaces into the respective jaw and a protrusion extending from the other of said contact surfaces away from the respective jaw wherein said protrusion engages in said elongate recess, wherein the elongate recess has the shape of a channel or a slot extending completely along a linear axis which is substantially parallel to a plane of the surface wherein the protrusion extends in the direction of a middle axis of the locking element and said axis of said channel or slot extends substantially perpendicular to said middle axis, wherein said protrusion engages into said channel perpendicular to said axis of the channel and wherein said channel or slot opens out into neighboring grooves and is bounded on the opposite side of one of the grooves as viewed along the channel or slot axis by an abutment element.
