    Abstract: Apparatus and methods for measuring spacing between first and second bone screws engaged with first and second bone structures are provided. An apparatus comprises first and second arms operably engaged with a single pivot pin. The first arm includes a distal end adapted to engage the first bone screw, and a proximal end comprising a graduated scale. The second arm, operably engaged with the first arm via the single pivot pin, includes a distal end adapted to engage the second bone screw, and a proximal end comprising an indicator segment slidably engaged with the graduated scale. A position of the indicator segment relative to the graduated scale is therefore indicative of a spacing between the first and second bone screws.

    Abstract: A femoral sizing guide comprises a body (6), a superstructure (40) and a stylus (53). The body (6) is arranged to rest against a resected femoral surface and has first and second feet (12) arranged to extend underneath respective posterior condyles and rest against posterior condylar surfaces of the femur. The superstructure (40) is coupled to the body (6) and is arranged to slide parallel to the resected femoral surface towards and away from the feet (12). The stylus (53) is coupled to the superstructure (40) and arranged such that when the body (6) rests against the resected femoral surface a tip (60) of the stylus (53) extends over the femur such that sliding the superstructure (40) towards the feet (12) causes the stylus tip (60) to contact the anterior cortex of the femur. The superstructure (40) further comprises a first guide hole (52) defining a first alignment axis extending into the resected femoral surface at a predetermined distance from the level of the stylus tip (60) in the plane of the resected femoral surface. The body (6) defines a second guide hole (22) defining a second alignment axis extending into the resected femoral surface at a predetermined distance from the feet (12), the distance between the first and second guide holes (52, 22) varying as the superstructure (40) slides relative to the body (6).

    Abstract: A tool set for preparing a joint, inserting an implant or removing an implant from a joint in an open or less invasive procedure generally comprises a set of nested tools, pin guides, jigs, and/or immobilization elements. The nested tool set comprises at least one pin and at least one cannulated tool. In some embodiments, the cannula can comprise tangs that project from the distal end of the cannula. The tangs can be offset such that drilling would remove different amounts of bone relative to drilling through a centered drill guide. The cannulated tool kit generally can comprise at least one tool guide/cannula, drill bits/reamer, syringe, and/or inserter. With the pin positioned into the joint, at least one cannula is positioned over and around the pin. The channel of the cannula guides the other tools into the joint. A plurality of cannulae in a nested arrangement can be used to afford selectively sized channels for tools and/or implants based on selected cannulae configuration. Jigs can be used to facilitate the procedure. Multiple implants can be placed to immobilize the joint.
