摘要: 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.

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 threaded through opening in the implant. The assembly includes a convexly rounded ring shaped locking insert which mates with the through opening. The head of the fastener includes a concentric flange that engages the locking ring into a locking relationship with the threads of the opening as the fastener is tightened into position. Preferably the locking ring is integral with the head of the fastener. The locking ring is made from a material that is more deformable than the material of the plate.

摘要: 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.

摘要: 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.

摘要: The invention comprises an implant having a first end section and a second end section, where the first end has a cancellous thread for implantation in a first section of bone and the second end includes expansion slots and barbs or wings, that that resist movement out of a second section of bone. These anchors expand outwardly when a rigid wire, such as a k-wire is fed through a central cannulation in the implant and either the wire expands in diameter or the cannulation decreases in diameter. The implant also includes a collar intermediate to the first and second section which includes one or more surfaces to allow the first section to be screwed into a first bone section.

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.
