A bone retractor that may be used as a femoral elevator. The bone retractor includes a clamp for attaching the bone retractor to an operating room bed rail, a post attached to the clamp via a hinged joint, a mount slidably attached to the post and a hook coupled to the mount which in turn is attached to the post. A shaft passes through the interior of the post and attaches to clamp. The clamp has a lower jaw and an upper jaw. An opening is formed in the lower jaw and an end of the shaft is engaged in the opening. The shaft has two sections with a universal joint connecting these two sections. The born retractor is attached to the operating room bed rail by applying clamp to the bed rail. With bone retractor attached to the bed rail, the post is lowered towards the wound. The hook is placed under the bone, and the bone exposed by holding the hook or the post and lifting the bone out of the wound. A knob is tightened to lock the post and consequently the hook in the raised position while the surgeon performs the surgery. When the surgeon is ready, the bone is lowered in the wound by loosening the knob and slowly placing the bone in the desired position in the wound.
