Abstract: A distal radius plate having a head with a complex palm shaped profile which flares from the sides of the plate to a leading edge that includes a central oblique linking area that helps to mark the placement of the plate relative to the radius. Further, the plate includes an oblique depression that extends from the rounded pinky side of the head and gradually morphs into the elevated styloid prominence in one diagonal direction, and rises less gradually upward into the lunate prominence on the other side of the head. A proximal plate portion mimics the spiral of the radial bone as it spirals along the longitudinal axis, and includes a tighter radial bend. The head includes holes or bores for pegs which extend into the distal portion of the radius to lock fragments into position. In the first embodiment, the angles of the pegs are fixed. In a second embodiment, one or more of the peg holes are provided with a variable axis locking mechanism assembly and the remaining holes are fixed.

Abstract: An orthopedic plate has a portion with a curved bottom surface that is designed to extend longitudinally along the bone and change the inferior curve as it advances proximally along the bone from a shallower to a sharper radius and further spirals downward as the plate advances. The plate includes a set of tabs, offset from the longitudinal axis of the plate to provide for better pullout values. The ears may be located at the terminal portion of the plate or somewhat more intermediate to the terminus of the plate, depending on the intended application. A point in the center of the central screw hole can be used to define the origin of the plate, and the angles of the screw and/or pegs holes can be referenced with Z, Y, and Z coordinates relative to this central hole.

Abstract: The present invention relates to an orthopedic plate and screw system and instruments for surgical fixation of a small bone or bones including specifically the small bones of the spine. The plate facilitates three dimensional contouring to provide for a variety of applications and to accommodate individual variation in bone shape. The plate has a modified x shape including a central trunk portion including one or more screw holes along a longitudinal axis and a set of divergent upper and an oppositely extending set of divergent lower arms, each arm including screw holes which are placed at a radially equal distance but which diverging asymmetrically from the longitudinal axis relative to its paired upper or lower mate. The screws of the system are self-starting, self-tapping screws including the option of partial or full cannulation. In a further embodiment, the plate is intended for use through the length of the spine.
