摘要： 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.

摘要： 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 8 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.

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： 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： A locking mechanism assembly to allow locking of a fastener in an orthopedic implant having its axis at a variable angle relative to the axis of a concavely rounded through opening in the implant. The assembly includes a convexly rounded ring shaped locking cam insert which mates with the through opening and further which includes an expansion slot. The cam insert includes two cam raceways on the inside that are engaged by cam members on the head of the fastener. The cam members increase radially and expand the insert in the through opening to hold it in position by friction. The cam insert further includes a stop member that inhibits the cam insert from rotating as the fastener is rotated in the cam insert and locks it into the desired position.

摘要： The present invention relates to a method of designing an orthopedic implant in which a plurality of samples of the bone are selected and a CT scan of each of the samples of the bone is taken so that the data from the CT scan can be used to generate a 3D graphical solid body model of each of the sample of the bone. The 3D graphical models are placed into a category of one or more of average, small, and large, and the center of mass and an X, Y and Z plane for each model is determined. The 3D graphical models for one category is assembled and aligned at the center of mass to create a categorized composite 3D graphical solid body model of the bone. The categorized composite 3D graphical model is sectioned at a specified interval to create a lofted contoured surface of a selected thickness which is cut to create a categorized implant profile. The categorized implant profile is graphically fit on the categorized composite 3D graphical model and on the 3D graphical model of each of the sample of the bone in a category to check for conformity to the surface of the bone. The categorized implant profile is used to create a design of the implant.
