Abstract: An orthopaedic fixation clamp for use in an external fixation system and its method of use are presented.

Abstract: A method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure. A femoral implant achieves intramedullary fixation as well as fixation into the femoral head. To optimally position the femoral implant, a minimally invasive incision is aligned with the greater trochanter and the wound is developed to expose the greater trochanter. Various reamers are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur.

Abstract: The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing minimally invasive knee surgery.

Abstract: A mobile bearing unicondylar tibial knee prosthesis includes a tibial base plate and a tibial articular surface component. The inferior surface of the articular surface component engages the superior surface of the base plate in sliding relationship. The tibial articular surface and a stop on the tibial base plate define a tab and groove engagement between them such that the tibial articular surface component is permitted to slide anteriorly-posteriorly on the tibial base plate while movement of the tibial articular surface component superiorly away from the base plate is restricted.

Abstract: A surgical instrument having a grip, a reference structure and an alignment head and method of using. The reference structure has at least one reference element that is registrable in a computer assisted navigation system. The reference element may be a reflective structure for use in an optical tracking system, wire loop for sensing a magnetic field, or other suitable device. The alignment head has a substantially planar alignment surface and may also have a plurality of outwardly extending projections or an electrocautery electrode disposed along an edge of the alignment surface and extending parallel to the alignment surface. The projections may be engaged with an anatomical structure to hold the alignment head in a desired position as the alignment surface is used as a guide to mark the anatomical structure. The disclosed instrument may be used when resecting a femur to prepare the femur to receive the femoral component of a prosthetic hip joint.

Abstract: An instrument configured to receive and retain a prosthetic component to facilitate the implantation of the same. In one exemplary embodiment, the instrument includes an actuator and holder secured to the actuator. The holder may include an elongate body and a head portion having a plurality of resiliently deformable arms sized and shaped to receive the prosthetic component therebetween. Additionally, the holder may be placed within a guide in the actuator along which the holder may be translated. By moving the actuator, the holder may be correspondingly translated and the resiliently deformable arms compressed to restrict translation and rotation of the prosthetic component relative to the holder.

Abstract: A system for preparing a surface of an anatomical structure, such as a bone or cartilage, for example, to receive an orthopaedic implant. The system includes a surgical instrument for preparing the surface and a guide engageable with a follower of the surgical instrument. The guide includes a track or path configured to guide the follower and prepare a desired surface on the anatomical structure. The guide facilitates guidance of the surgical instrument in two dimensions.
