Patent number: 9510876Abstract: An intramedullary fixation system is configured to be fixed to first and second bone segments that are separated by a defect. The system includes an intramedullary fixation member that includes first and second wire segments that are twisted about each other so as to define a plurality of intersections. A distal one of the intersections is separable, such that rotation of the fixation device in a medullary canal causes bone material in the medullary canal to apply a counterforce to the wire segments that causes the distal intersection to separate, thereby driving respective distal ends of the wire segments into the bone segment, such that subsequent movement of the intramedullary fixation member a toward the first bone segment causes the second bone segment to move toward the first bone segment. The intramedullary fixation system can further include a fixation clip that anchors the intramedullary fixation member to the first bone segment.Type: GrantFiled: August 23, 2013Date of Patent: December 6, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Andreas Appenzeller, Daniel Fluri

Patent number: 9463056Abstract: An adjustable length bone screw is provided that has a shaft that can be cut at any of several predetermined positions. The adjustable length bone screws can be provided in a kit containing many bone screws having the same or different initial lengths, and these screws can be cut to the desired length for use in the surgical procedure prior to, or during, the surgical procedure. The adjustable length bone screws have a plurality of threaded shaft sections that are separated by a plurality of unthreaded shaft sections along the length of the shaft. The threaded sections have preferably at least two cutting flutes extending longitudinally along the shaft. The invention provides the adjustable length bone screws, a tool for cutting the bone screws to a desired length, kits containing the bone screws and optionally the cutting tool, and methods for using the screws and/or the cutting tool in preparation for or during a surgical procedure.Type: GrantFiled: June 15, 2015Date of Patent: October 11, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Andreas Appenzeller, Daniel Fluri
