Disclosed herein are reference feet for inserters and method of use thereof. The reference feet can include a body, a tine, a first arm, and a first base. The body can have a longitudinal axis and define an engagement fixture oriented parallel to the longitudinal axis and sized to receive a complementary fixture of an inserter. The tine can extend from the body along the longitudinal axis and including a protuberance sized to engage a stop of the inserter. The first arm can extend from the body. The first base can be attached to the first arm and have a planar surface arranged at an angle relative to the longitudinal axis.

A universal jig is compatible with bone plates of varying size, in which different plate sizes having different hole configurations. For example, a longer bone plate may have a first hole pattern along a given length thereof, while various shorter bone plates may have differing hole patterns along respective corresponding lengths. The universal jig includes a combination of hole groupings to provide a jig hole for each hole in the differing hole patterns of the longer and shorter plates, so that the universal jig is useable with a variety of bone plates having disparate hole patterns. For any given bone plate length and hole configuration, a masking cover may provided to attach to the jig. The masking cover masks off unused jig holes, so that only those jig holes intended for use with a particular bone plate are left exposed.

Bone plate fixation system

Bone plate fixation device

A tool for gripping an orthopedic implant having a recess. The tool includes a plurality of engagement members which extend freely from the tool body to their free ends. An elongate biasing member having a radially enlarged portion at its distal end is positioned along a central axis of the tool with its radially enlarged portion positioned between the engagement members. Axial translation of the biasing member biasingly engages the radially enlarged portion with the engagement members and resiliently deflects the engagement members from a contracted position to an expanded position. The engagement members are insertable into a recess in the implant when in the contracted position and outward biasing of the engagement members firmly secures the implant to the tool. The use engagement members which define a non-circular cross sectional shape and a correspondingly shaped recess in the implant inhibits relative rotational movement between the tool and implant.
