摘要： The present invention is a fully contoured calcaneal plate having substantially no planar surfaces except at the origin. The contoured plate includes radiused sections, one extending inferior to superior is curved inferior to superior in a shape which is close to cylindrical and which approximates the shape of the cuboid bone. The second radiused section is curved in the vicinity of the anterior strut, and in particular at the inferior portion of the plate, to accommodate the peroneal tubercle. The plate has a rectangular or modified ovoid body section and a dog boned shaped tail with triangular placed holes for fixation.

摘要： 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.

摘要： The present invention relates to an orthopedic screw having a torque driving head with spherical surface for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a modified cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4 to about 12° and the major diameter of the screw remaining substantially the same meaning that the major diameter is constant to about +/−0.05 mm along the length of the threaded portion. The screw includes a multilobe torque driving recess joined to a cylindrical recess that corresponds to a cylindrical post on the torque driver so as to form a press fit which acts to self-center the screw, to help avoid stripping of the screw/driver interface and to hold the screw in place on the torque driver prior to implantation. In a further embodiment, the screw includes a variable pitch portion for about half of the length starting from the distil end. The screw can be used be itself, or with a plate. Further a new method of using the screw with a plate is presented in which the screw extends through a cortical section of bone into a cancellous portion but not through the adjacent cortical.

摘要： An orthopedic plate system comprises a plurality of fasteners such as pegs or screws and a plate having two sets of holes for the fasteners. The first set of at least one hole includes internal threads that receive a fastener having a head which includes external threads that mate with the internal threads of the hole to lock the fastener at a fixed angle relative to the plate. The second set of at least one hole is devoid of internal threads and has a concavely rounded internal surface and which receives a convexly rounded external surface of a locking insert, which receives a variable axis fastener. The variable axis fastener causes the locking insert to expand to lock the variable axis fastener at a selected angle relative to the plate.

摘要： 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.

摘要： 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.
