Abstract: An orthopedic plate has a first end including a locking screw hole that receives a locking screw and spaced from that hole is a closed compression housing that extends from the bone-facing side of the plate and which receives a compression screw that forms an angle of from about 10° to about 70° with a longitudinal axis of the plate. The compression housing is not located on the medial line of the plate, but is peripheral to the medial line, either in the longitudinal or the medial direction of the plate.

Abstract: An orthopedic plate is specifically configured for use in osteotomies, in which part of the plate extends into a portion of a first bone segment and part is external to the cortical surface of an adjacent bone segment to fix the segments to allow them to fuse. The plate has a first end and a second end where the end which is inserted into the bone has a chamfer and a through hole having a hole axis optionally at an oblique angle to the longitudinal axis of the plate, and which can receive a screw, peg or pin. The second end of the plate includes a locking screw hole and optionally including a compression slot extending in a direction toward a screw hole in the opposing end. Optionally, the non-locking hole has a shroud that forms an arc or portion of a cylinder over the hole. A plate driver having a recess that holds the plate is used to insert the plate into the bone.

Abstract: The invention comprises a lateral ankle fusion plate, a jig for use with the fusion plate and a method for ankle fusion of the joints between the tibia, the talus, and the calcaneus. In addition, a separate fusion screw from posterior to anterior through the calcaneal tuberosity into the distal tibia is useful and can be placed using the targeting jig of the invention. The plate includes a C-shaped stirrup portion that wraps the bottom of the calcaneus and is provided with a screw hole for a T-T-C-fusion screw. A C-shaped targeting jig is provided that interfaces with the plate to allow for placement of the calcaneal screw and has an additional attachment for placement of the independent fusion screw so as to avoid impingement with the plate, and plate screws. The invention also relates to a method of surgery that incorporates the use of the plate, the jig and the tibial/talar/calcaneal fusion screw for an arthrodesis of the ankle joint.

Abstract: A computer assisted surgery (CAS) system and method for preparing an anatomical structure to receive an orthopaedic implant. The method generally involves the steps of determining a contour of the anatomical structure by using the CAS system to acquire a plurality of points on the anatomical structure and provide a best fit approximation of the anatomical structure based on the plurality of points, selecting an implant to replicate the anatomical structure, and preparing the anatomical structure to receive the implant.

Abstract: The present invention relates to an orthopedic fastener driver which can be used with a variable angle fixation system, and in particular in which the driver has a variable angle drive tip that is capable of screwing a fastener in an orthopedic plate assembly at a variable angle relative to the drive axis of the driver, and further wherein the driver has a drive mechanism including an interference clutch mechanism that disengages so as to limit the relative depth of the fastener in the plate assembly as to avoid driving the fastener or fastener assembly through the plate.

Abstract: Instruments for use in resecting, reshaping, and preparing the end of a bone to receive an implant. The instruments may be equipped with indicator devices in the form of light-emitting devices to project an indicator onto the bone. Examples of such instruments may be a cut guide equipped with a built-in cut plane indicator device and a cut plane indicator device for use with existing cut guides. The cut plane indicator device may provide a visual indication or cue on a surface of the bone indicating where the cut plane of the cut guide will intersect the bone.

Abstract: A method and apparatus for remote alignment of a cut guide. The cut guide may be positioned on a base which is remote from a surgical site and positioned on a docking station. An alignment jig is removably positioned on a bone and is used to provide alignment information to the docking station. The docking station remotely aligns the cut guide relative to the base. Thereafter, the cut guide and base are removed from the docking station and positioned on the bone in place of the alignment jig. A surgical procedure using the cut guide may then be completed.

Abstract: A robot is characterized by an external measurement device. The robot generates a first point cloud of data. The external measurement device generates a second point cloud of data. These two points clouds are analyzed to determine an accuracy of the robot.
