Abstract:
1. A jig for identifying a point on a femoral head in alignment with a central axis of an associated femoral neck, the jig comprising: a first member defining a plane and having a locating member disposed in the plane to at least partially receive the femoral neck, the locating member comprising confronting surfaces adapted to substantially encircle the femoral neck, said confronting surfaces comprising a first part having a first end and an opposite end remote from the first end, and a second part; a hinge, the first end being mounted by said hinge at the second part, the first part being moveable between an open position in which the opposite end is separated from the second part by a distance sufficient to receive the femoral neck and a closed position in which the first and second parts define a wall adapted to substantially surround the femoral neck; a guide member mounted in spaced relation with respect to the first member and defining an axis at right-angles to the plane defined by the first member, the axis defined by the guide member intersecting the plane at a point a predetermined distance from said locating member, said axis defined by the guide member being substantially coincident with the central axis of the received femoral neck; and an elongate alignment member mounted with respect to the first member, the alignment member being spaced from and extending parallel to the axis defined by the guide member.
