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.

An orthopedic screw having a torque driving head with a rounded side a spherical wall for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a 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. In a further embodiment, the screw has an insertion tip which is forms a portion of a sphere.

The present invention relates to an orthopedic plate and screw system and instruments for surgical fixation of a small bone or bones. 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.

An orthopedic plate has a first end including a locking screw hole that receives a locking screw and spaced from that hole is a compression housing that extends from the bone-facing side of the plate and which receives a compression screw that forms an angle of from about 10° to about 70° with a longitudinal axis of the plate. In a further embodiment, the plate also includes a second end with a chamfer for insertion of the plate into bone, and in a still further embodiment, the plate is an MTP plate.

An orthopedic plate is designed for opening osteotomies and includes a contoured double tabbed or butterfly shaped plate portion which can accommodate selective fixation including locking, variable locking and non-locking. The plate also includes a centrally located osteotomy support that maintains the opening between bone segments at a spaced relationship. The support can be integral to the plate, or can be modular, i.e. a separate and adjustable segment which can be changed to accommodate the desired geometry of the osteotomy site.

The present invention relates to a cannulated orthopedic screw having a torque driving head with a spherical wall for multiaxial use, a rounded fluted insertion tip and a threaded portion including a cancellous thread contiguous with a non-threaded portion. The threaded portion has a major diameter defined by a spiraling cancellous type thread and a minor diameter. The screw includes a multilobe torque driving recess.

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.

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.
