    摘要： A set of surgical products which includes an attachment mechanism for modular surgical products. The set includes a plurality of first components and a plurality of second components. One of the first components and one of the second components are to be selected for engagement with each other. The components each include an indexing means including a key on the first components and a corresponding slot on the second components for mating with the key. The orientations of the keys and slots vary, so that only first components having a key orientation that is similar to and aligns with the slot orientation of a second component will properly mate together and so that first components will not properly align and mate with second components having slot orientations that are different from the respective key orientation.

    摘要： An orthopaedic prosthesis for implanation in a bone, the prosthesis including a collar extending outwardly therefrom. The collar includes an access recess aligned above the bone cement when the stem is implanted with cement in bone, or aligned above the bone/implant interface when the stem is biologically affixed to the bone. The access recess may be a dimple partially extending into the collar or it may be a through hole. The dimple provides a preset drill start for a drill to be aligned therewith for drilling through the collar to form a hole therethrough. In either case, whether starting with a dimple and then forming a hole or starting directly with a through hole, the hole may be progressively enlarged by use of sequentially larger drill sizes. Tools, such as chisels or the like, are inserted through the hole in the collar to break up the bone cement beneath the collar if a cemented stem, or to help break the bond between the stem and the bone if a biologically affixed stem, to help loosen the prosthesis from the bone to facilitate removal of the stem. A method of removing such a prosthesis is also disclosed.

    摘要： An osteotomy guide assembly for femoral neck osteotomy includes a saddle locator assembly and a saw guide attachment. The saddle locator assembly includes a barrel-shaped locating device that locates the saddle region of the proximal femur. The barrel further includes a transverse support bar extending from the barrel. The barrel is positioned over an intramedullary shaft which is temporarily positioned in and extends from the medullary canal of the femur. A saw guide is used in conjunction with the saddle locator assembly. The saw guide is attached to the support bar by a single locking means which provides for positional adjustment of the saw guide relative to the support bar in two directions, including adjustment in the anterior-posterior direction along the transverse support bar and axially along the femur via a post which extends from the saw guide.

    摘要： An orthopaedic holding forceps 1 for simultaneously holding a screw 60 and a screwdriver 70. The forceps 1 includes a distal tip 42 having an upper chamber 43 adapted for receiving an enlarged gripping head 72 of the screwdriver 70 and a lower chamber 44 adapted for receiving the enlarged head 61 of screw 60. The distal tip 42 also includes an interconnecting chamber 45 between the upper and lower chambers 43 and 44 adapted for receiving the distal driving tip 73 of the screwdriver 70.
