    摘要： A long bone axis finder has a shaft extending along an axis and a first and second end. A tip portion is provided for releasable coupling to the shaft first end. A wedge element having an open side is provided for lateral engagement with said shaft. The wedge element is slidable along said shaft in a direction from the second to the first end. The axis finder is inserted into a long bone medullary canal until the tip portion engages a narrower portion of the canal. The wedge portion which is larger than the tip is laterally placed on the shaft and engages a portion of the canal closer to the shaft second end.

    摘要： 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.

    摘要： A method for preparing a proximal femoral canal of a patient during total hip replacement surgery uses a shaping instrument or broach having a proximal portion with an anterior surface, and a posterior surface, each surface being spaced apart from a medial-lateral plane through the shaping instrument. A handle portion having a proximal portion having a first longitudinal axis is connected to a transition portion having a second longitudinal axis and a distal portion having a third longitudinal axis. Wherein the handle comprises a dual offset including a first compound bend between the transition portion and the proximal portion and wherein, when following a direction from the transition portion to the proximal portion, the first compound bend includes a bend in the posterior direction and a bend in the lateral direction, and wherein the first compound bend is less than 90 degrees. No plane extending through the proximal portion is coplanar with a plane extending through both the transition portion and the distal portion.
