    Abstract: The present invention is a MTP plate that has a first embodiment with a profile having bilateral mirror symmetry of the about a transverse plane with an angle of about 5° for dorsiflexion and an angle of about 10° for valgus. Both ends of the plate include a central arm having a slot for compression and two offset arms having offset ears with locking screw holes that provide for multiplanar compressive fixation. The bone contacting surface of the plate is radiused to allow the plate to be in snug contact with the bone. In a second embodiment of the plate for revision surgery, the proximal end of the plate includes a metatarsal extension and the plate has a central locking hole for securing bone graft.

    Abstract: A driver assembly may include a fastener and a driver. The fastener may have a head with upper and lower surfaces. An engagement portion may be located in the upper surface proximate a perimeter portion thereof. A shank may extend from the lower surface of the head and a breakaway portion may extend from the upper surface of the head. The driver may include a shaft having a body with a first end having a fastener-engaging portion. The fastener-engaging portion may have an outer driving geometry engaged with the engagement portion of the fastener when in an engaged position. The first end may further include an opening therein. The opening may receive at least a portion of the breakaway portion when in the engaged position.

    Abstract: A cannulated compression screw is used as an orthopedic implant and has a threaded distal end with an insertion tip that includes at least one and preferably two, three or four flutes to allow the screw to be self-tapping. Optionally, the screw also includes one or more reverse cutting flutes proximal to the insertion tip. The distal threads are cancellous threads having a generally constant minor diameter and a generally constant major diameter and a generally constant thread pitch. An intermediate portion of the screw is non-threaded and the proximal end includes a compression wedge or taper that has at least one, and preferably two to five flutes that terminate before the top of the screw. The proximal end further includes a radiused bevel to the terminal surface that includes a hexagonal torque driving recess. The diameter of the non-threaded shaft section is constant distal from the compression wedge to the distal tip where it defines the minor diameter of the threaded portion. The screw optionally includes a tapered insertion tip.

    Abstract: A surgical drill guide for positioning, aligning, and of holes to be drilled in bone tissue has retaining means that holds the position and alignment of the drill guide body in a releasable manner with respect to a fastener hole in an orthopedic implant. The retaining means is a key guide that mates with a key way or key ways in or around a threaded locking hole of an orthopedic plate for alignment of a pilot hole and method of using the guide. The key guide has 2 to projections that extend in the direction of the axis of the hole, such as hemi cylindrical projections, and the plate has a corresponding female key way that receives the retaining means. The invention also relates to a method of aligning a locking fastener in a plate at a desired angle relative to a bone by using a surgical guide having a key interface with the plate to position and align a pilot hole.
