Method and apparatus for preparing a seating surface of prescribed depth, contour configuration and area delineated by a prescribed peripheral boundary extending along the bone of a natural joint at which a prosthetic device is to be implanted includes positioning a guide on the bone, the guide having a guide slot following a path geometrically similar to the peripheral boundary of the seating surface, inserting a cutting device altitudinally through the guide slot at any selected location along the path of the guide slot, and translating the cutting device along the guide slot to cut an outline groove in the bone coincident with the peripheral boundary of the seating surface. The guide then is removed from the bone, and portions of the bone lying within the area delineated by the outline groove are removed to establish the seating surface.

Femoral resection tools of the present invention include a posterior condyle alignment guide, an IM rod with an adjustable valgus bushing assembly, left and right external rotation plates, an anterior sizing boom having a stylus and a pair of medial/lateral drill guide assemblies (in one embodiment of the invention the drill guide assemblies are the combination of medial/lateral extension arms and attached (detachable) proximal positioning fixtures; in another embodiment, the proximal positioning fixtures are not part of the drill guide assembly per se), a plurality of self-tapping screws, proximal positioning fixtures (apart from any positioning fixtures that may be integrated into a drill guide assembly), and different size cutting guide blocks, each adapted to fit over the proximal positioning fixtures. Methods for utilizing the aforementioned tools so that five resections can be performed are also described.

An apparatus and method for reaming a bone, facilitating pre-implantation alignment of a prosthesis using trial components, and preparing a bone site for anti-rotational implantation of the prosthesis is provided. The apparatus includes a boring end, a mating end disposed opposite the boring end, and a keying aid disposed between the boring end and mating end. The keying aid facilitates preparation of the bone canal for anti-rotational placement of a prosthesis having an anti-rotational component, or key. The method includes using the apparatus to ream a bone canal, conduct alignment trials, mark the bone canal with the desired orientation of the trial component, and insert the prosthesis into the marked bone canal for anti-rotational engagement with the reamed bone.

An apparatus and method for reaming a bone, facilitating pre-implantation alignment of a prosthesis using trial components, and preparing a bone site for anti-rotational implantation of the prosthesis is provided. The apparatus includes a boring end, a mating end disposed opposite the boring end, and a keying aid disposed between the boring end and mating end. The method includes attaching a power tool to the mating end, reaming a bone canal with the boring end, detaching the power tool, attaching a trial component, conducting alignment trials, maintaining the apparatus in the desired position, detaching the trial component, cutting at least one keyway in the bone canal using a cutting device and the keying aid, removing the cutting device, removing the apparatus from the reamed bone canal, and inserting the prosthesis into anti-rotational engagement with reamed bone by aligning the key on the prosthesis with the keyway in the bone canal.

An improvement in a trialing system and method for use in connection with the implant of a prosthetic joint component having a first part for engaging bone at an implant site to secure the component at the implant site, and a second part for enabling articulation of the prosthetic joint. A trial first member corresponds to the first part of the component, a trial second member corresponds to the second part of the component, and an offset adapter facilitates selective coupling and uncoupling of the trial first member and the trial second member with the trial second member offset from the trial first member and placed at a selected angular orientation relative to the offset adapter. Thus, during a trialing procedure the trial second member is selectively released readily for replacement of the trial second member with alternate trial second members, and replacement of the offset adapter with alternate offset adapters, as well as facilitating the selected angular orientation of a trial second member relative to an offset adapter, as required in order to expedite an accurate trialing procedure.

An instrument for holding a surgical tool or bone implant includes a handle with a bearing surface formed in one end for engaging the surgical tool. An elastically deformable plate is mounted on the handle body the plate having a catch element formed on a leading end thereof adapted to engage a coupling element formed on the surgical tool. The elastically deformable plate includes a cam follower formed in a recess thereon and includes a deformable spring section intermediate the can elements and the plate end with the catch element. An elongated pivotable loading member is rotatably mounted on the handle body. The loading member includes a cam surface for engaging the cam follower surface on the deformable plate. The cam surface on the loading member is shaped to elastically deform the elastically deformable plate section in a direction away from the plate catch element to thereby load and maintain a connecting force between the plate and the surgical tool or bone implant.

An orthopaedic instrumentation having an intermediate piece that has an opening for receiving an intramedullary reference. The intermediate piece such as a tibial template or a cutting guide is located on the resected tibia or femur in a manner that it optimally covers the resected surface of the tibia or the femur. A bushing guide is provided for mounting on the intermediate piece. The bushing guide has a circular opening. An offset bushing is rotatably mounted in the opening in the bushing guide. A trigger flange is slidably mounted on the offset bushing. The trigger flange can slide back and forth relative to the offset bushing. An indicia is formed on the upper surface of trigger flange. The indicia when aligned with one of the indicia on the offset bushing body measures the offset of center of a bore in the trigger flange from center of the offset bushing. The offset bushing can rotate around its longitudinal axis in the opening in the bushing guide.
