Abstract: A bone fixation system having a plate with an axle and a blade or “beam” configured to engage with the axle and reside proximate to a subchondral fragment of bone in upon installation of the plate. The beam is operable to rotate about the axle on the plate and reposition the subchondral fragment of bone.

Abstract: According to one embodiment, a bone fixation system includes a plate having a first opening a beam configured to traverse through the first opening and reside proximate to a subchondral fragment of bone in an installed position. The beam may be operable to rotate about an axis of rotation proximate to the first opening and reposition the subchondral fragment of bone.

Abstract: An offset reference guide for use in determining an offset value for orthopedic fasteners to be used with surgical hardware. The reference guide may include a reference surface against which the surgical hardware may be disposed. In turn, an orthopedic fastener may be inserted through a fastener hole of the surgical hardware and accepted by a fastener relief of the guide. Upon fully seating the orthopedic fastener relative to the surgical hardware, the distal end of the orthopedic fastener may align with one of a set of offset indicia calibrated relative to a known length of the orthopedic fastener. In turn, an offset value for the surgical hardware may be determined that may, for example, be used to augment measurements of bore lengths taken for a bore into which an orthopedic fastener is to be disposed.

Abstract: Sensing technology methods related thereto for determining cut through of bone and a depth of penetration of a working portion of a surgical instrument (e.g., an oscillating saw blade in a cut). A first sensor outputs a first signal representative of a displacement of the cutting edge of the saw blade in the cut. A second sensor outputs a second signal representative of a force applied to the cutting edge of the saw blade. As such, monitoring the first and/or second sensor may allow for the saw to be stopped upon completion of a cut (e.g., when the saw passes completely through a medium to be cut or upon reaching a predetermined depth for the cut).

Abstract: A measurement system and method for determining a depth of penetration of a working portion of a surgical instrument (e.g., a rotating drill bit in a bore). A first sensor outputs a first signal representative of a displacement of the leading edge of the drill bit in the bore. A second sensor outputs a second signal representative of a force applied to the leading edge of the drill bit. A processor outputs a third signal representative of the depth of penetration of the leading edge of the drill bit when the leading edge of the drill bit passes from a first medium having a first density to a second medium having a second density. The third signal is based on the first and second signals.
