20090088807 | Locking Screw System With Relatively Hard Spiked Polyaxial Bushing - A polyaxial locking screw system includes a bone plate defining a plate hole with an inner spherical surface and a relatively harder split polyaxial bushing with a outer spherical surface provided within the plate hole for receiving a bone screw. In one embodiment, the plate is formed from titanium alloy, while the bushing is formed from a cobalt chrome alloy. The outer surface of the polyaxial bushing includes a plurality of spikes. When the screw is inserted into the bushing, since the bushing material is considerably harder than the plate material, the forceful expansion of the bushing during screw insertion causes the spikes to penetrate into the inner spherical surface of the hole, thereby increasing the frictional engagement of the bushing to the plate to lock the screw at a desired angle. | 04-02-2009 |
20090143825 | Distal Tibia Plating System - A distal tibia plating system includes anterolateral and medial plates. The anterolateral plate includes a shaft with both threaded first fastener holes and compression slots along its length. The head includes a first row of four threaded fastener holes arranged transversely to the longitudinal axis, a non-threaded compression screw hole, and a plurality of distal tabs. Each tab includes a ring with a single threaded fastener hole and a bridge that couples the ring to the distal end of the plate. The bridge is configured to bend preferentially in a desired direction and to allow tab removal. The medial plate is a low profile plate including a shaft and a relatively enlarged distal head. Several fasteners can be used with the plates. A plate holder is provided to maneuver the plates subcutaneously. | 06-04-2009 |
20100137868 | Method of implanting a modular fracture fixation system - A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one diaphyseal plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one diaphyseal plate. The system preferably includes several end plates and diaphyseal plates to accommodate anatomy of various sizes. | 06-03-2010 |
20120323281 | Method of Implanting a Modular Fracture Fixation System - A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one diaphyseal plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one diaphyseal plate. The system preferably includes several end plates and diaphyseal plates to accommodate anatomy of various sizes. A method for coupling the plates to the bone is also provided. | 12-20-2012 |
20130006312 | Plate Holder for Manipulating Bone Plate - A plate holder is provided to facilitate percutaneous introduction of a bone plate, positioning of the plate on a bone surface, and stabilizing the plate while a fastener is inserted through the plate into the bone. The plate holder includes a proximal handle, a distal mount, and an arm extending between the handle and the mount. The mount includes a first portion which seats within a slot on the shaft of a plate, and a second portion at which the shaft is coupled and which includes a tapered proximal side. A set screw hole is provided through the first and second portions, and a set screw is provided therein. When the first portion is seated in a compression slot of a plate and the set screw is driven to seat, the set screw locks the mount to the plate. | 01-03-2013 |
20140039560 | Bone Plate with Pre-assembled Drill Guide Tips - Removable drill guide tips are pre-assembled into threaded holes of a bone plate. The tips may be used with an extension to together function as a conventional drill guide. After drilling, the extension or another tool is used to remove the tips from the plate. According to another use, the tip is used as a guide for a drill bit without any additional extension and then removed with a tool. | 02-06-2014 |
20140172021 | Bone Plate with Pre-Assembled Drill Guide Tips - Removable drill guide tips are provided for simultaneous assembly relative to the holes of a bone plate. The drill guide tips are used as a guide for a drill bit without any additional extension and then removed with a tool to allow insertion of a screw within the same hole in the bone plate. Alternatively, the drill guide tips may be used with an extension to extend the effective length of the drill guide. | 06-19-2014 |
20140243905 | Periprosthetic Plating System Including Plate with Integrated Cable Retaining Feature - A system, devices and methods are provided for facilitating stabilization of periarticular fractures. The system includes a compression plate and one or more of a cerclage cable for encircling the bone and securing the compression plate to the bone, a crimp lug for securing the cable in tension relative to the bone and/or a plate, and a supplemental plate coupled to the compression plate and adapted to receive bicortical or unicortical bone screws to further secure the compression plate relative to the bone. In addition, the system includes a cable tensioner for temporarily retaining the cable in tension and then applying a tension to the cable until a desired compression is effected between a plate and bone and while a cable retaining structure is secured to the cable to retain the applied tension on the cable. Also provided is a jig for use with plates for minimally invasive fracture stabilization. | 08-28-2014 |
20140243906 | Periprosthetic Plating System Including Plate with System for Retaining Tension on a Cable - A system, devices and methods are provided for facilitating stabilization of periarticular fractures. The system includes a compression plate and one or more of a cerclage cable for encircling the bone and securing the compression plate to the bone, a crimp lug for securing the cable in tension relative to the bone and/or a plate, and a supplemental plate coupled to the compression plate and adapted to receive bicortical or unicortical bone screws to further secure the compression plate relative to the bone. In addition, the system includes a cable tensioner for temporarily retaining the cable in tension and then applying a tension to the cable until a desired compression is effected between a plate and bone and while a cable retaining structure is secured to the cable to retain the applied tension on the cable.
