According to the invention, there is provided a trial implant and method of using same. The implant includes a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur. The bracket has an opening appointed to expose a portion of the resected bone of the femur, including guide structure for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. Removal of any portion of the bracket or guide structure is unnecessary following the shaping steps prior to performing a trial reduction.

Modular surgical instrumentation and a method of using same is provided, according to the invention. The instrumentation comprises a first bracket defining a generally U-shaped structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an elongated central opening appointed to expose a selected area of the resected femur, including a curved track for guiding a first shaping tool along a predetermined path for controlled shaping of a curved patellar groove in a portion of the selected area exposed through the opening. A second bracket defines a linear slotted bore extending generally parallel to the long axis of the femur for guiding a second shaping tool to form a relatively deep recess accommodating an intercondylar stabilizing housing of a knee implant. The second bracket has an internal surface defining a shape adapted for releasable engagement with the curved track, including mechanism for accurately aligning the slotted bore relative to the opening while forming the recess. The method of the invention comprises the steps of seating the first bracket described above on the distal aspect of the resected femur and moving the first shaping tool along the curved track to form a patellar groove in a selected area thereof.

A hip positioner for hip surgery (e.g., total hip arthroplasty surgery) is disclosed in which the patient is in a lateral position with the hip upon which surgery is to be performed facing upwardly. The patient lies on a support board having a plurality of holes therein with pins inserted in selected ones of these holes so as to prevent the patient from rolling on to the patient's back. A stanchion is inserted in at least one of the holes on the front of the patient at or above the level of the patient's hips and a support arm extends horizontally from the stanchion toward the upper hip. A pad is carried on the distal portion of the support arm for positive engagement with a desired anatomical feature of the patient (preferably the crest of ilium of the patient's upper hip) thereby to hold the patient in such desired lateral position during surgery.

According to the invention, there is provided a trial implant comprising a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur. The bracket has an elongated central opening appointed to expose the resected bone of the femur, including a pair of tracks for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. An end mill guide cooperates with the bracket to receive another tool to form a deep recess for accommodating a posterior-stabilizing housing. After the recess is formed, the guide is replaced with an insert having a posterior-stabilizing housing which covers the opening of the bracket and articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint. Removal of the bracket from the resected bone is unnecessary following the shaping steps prior to performing the trial reduction.

A bone cable strap and surgical instruments pass the cable strap around a bone, tension it, fasten it and trim the excess cable. The surgical instruments include: a cable passer which has an arcuate guiding member having a groove facing the bone to guide the cable around the bone; a cable tensioner having concentric tubular members with a cable clamp at one end, a nipple at the other end, and a handle in between such that turning the handle spreads the cable clamp away from the nipple; and a combination cable crimper-cutter having jaws with both crimping and cutting edges. The cable strap is comprised of a flexible cable having a ferrule pre-affixed to one end. The cable is passed under the bone using the cable passer. The free end of the cable is passed through the ferrule and the cable tensioner is used to draw the cable tight around the bone. The crimper-cutter is then used to fasten the ferrule in place about the cable and trim the excess cable.

The present invention provides a method and apparatus for preparing the proximal surface of a tibia to receive a proximal tibial prosthesis employing a reamer/alignment guide which is used to internally locate the central long axis of the tibia and a plateau planar which cooperatively engages with a guide handle attached to the reamer/alignment guide to accomplish the shaping of the proximal tibial surface. The reamer/alignment guide has a rod portion extending into the interior of the tibial shaft whose central long axis corresponds with the central long axis of the tibia. The guide handle is concentric with that rod portion such that the plateau planar assumes the proper alignment with respect to the central long axis of the tibia such that the proximal tibial surface is shaped relative to that axis in a simple and accurate manner.

An acetabular component for a hip replacement system comprises an acetabular shell, and a liner having a seal for insertion into the acetabular shell. In the preferred embodiment, the shell has a smooth tapered surface in its peripheral inner surface, and the liner has several annular ridges protruding from its outer surface. Upon insertion of the liner into the shell, the annular ridges of the liner come into sealing engagement with the smooth tapered surface of the shell. This sealing engagement substantially prevents a migration of debris along an interface of the liner with the shell. The liner is provided with several peripheral tabs for interference fit with several peripheral notches in the shell. An interlock comprising another liner ridge and a shell groove, provide a positive engagement to hold the liner in the shell as it bottoms therein. In an alternative embodiment, each notch is provided with protruding lips which project into the notch and firmly grasp one of the tabs of the liner upon insertion of the liner into the shell.

An orthopedic component for total joint replacement that comprises a metal tray () and polymer liner (), the metal tray having screw holes () for fixation with screws () to bone and a circumferential rim or wall () with a smooth inner surface (). The liner () is provided with a flexible sealing ridge () around its entire periphery, the sealing ridge being positioned so that it sealingly engages the tray rim so as to form a fluid-tight seal between the liner and the tray. The liner is provided with a locking mechanism comprised of tabs at the longitudinal ends of the liner which engage grooves in the front and rear of the tray. In this manner, the surgeon can readily install the liner within the tray after the tray has been surgically affixed to the resected skeletal structure by angling the liner and inserting a first tab into its respective groove and then by pressing the liner downwardly into the tray so that another tab at the opposite end of the liner engages its respective groove thus positively locking the liner with respect to the tray. Simultaneously with snap locking the liner within the tray, the flexible sealing ridge on the tray seals the liner with respect to the tray.
