The clamp has a central post, an upper vise plate and a lower vise plate urged together on the post, by a spring for provisional placement, a nut for positively locking the vise plates together on a frame, and a pin clamp that can be moved along the axis of the central post, and can receive and clamp either a bone pin or a bone wire. The pin or wire has unlimited angular movement in two planes. The clamp is a captive unit that requires no intraoperative assembly.
