Abstract

A fixation clamp is used in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements. The clamp has at least one clamping assembly having at least one reception to accommodate a fixation element along the longitudinal axis of the reception and at least one locking element extending through the clamping assemblies for blocking the position of the clamping assemblies in a defined angular position. Between the locking element and the at least one clamping assembly there is arranged a washer. The clamping assembly comprises a first contact surface and the washer comprises a second contact surface wherein the first contact surface is in contact with the second contact surface. The washer has a through bore and an opening extending radially from the bore to an outer surface of the washer.
