Patent number: 8142485Abstract: An implantable orthopedic device having a load-bearing element, such as a bone plate, with at least one opening for a fixation element and one insert which can be inserted in an inclined opening in a receptacle in the bore. This insert has an external form that is at least partially complementary to the internal form of the receptacle and a central through-bore for receiving the body of the fixation element such as a bone screw. The insert also provides a locking system for holding the insert in the receptacle, in which the insert exhibits at least one locking mechanism with which conformal locking with the load-bearing element may be achieved.Type: GrantFiled: June 10, 2008Date of Patent: March 27, 2012Assignee: Stryker Trauma SAInventors: Volker Buhren, Christian Lutz

Publication number: 20050273103Abstract: An intramedullary nail, comprises a proximal portion, a middle portion and a distal portion. The proximal portion has a longitudinal slot and the distal portion has at least one transversal bore. The proximal portion has a longitudinal axis and a longitudinal bore extending over the longitudinal extension of the slot in the distal direction. The longitudinal bore has an internal thread. An insert which is intended to be inserted in the longitudinal bore. The insert comprises a guiding bore in the form of a slot which is intended to receive fixing elements. The alignment of the guiding bore of said insert is transverse with respect to the longitudinal axis of the proximal portion. The insert has a compression screw adapted to be screwed into said internal thread of the longitudinal bore of the proximal portion to move a fixing element in the direction of the longitudinal axis of the intramedullary nail.Type: ApplicationFiled: August 8, 2005Publication date: December 8, 2005Applicant: Stryker Trauma S.A.Inventors: Thomas Wahl, Volker Buhren

Patent number: 6547791Abstract: The tibia nail comprises a tube including a continuous longitudinal bore and includes a proximal anchoring portion with several cross-bores, an adjoining connecting portion which is flexurally resilient in an anterior and posterior direction, a shank adjoining it, and a distal anchoring portion. The anchoring portion is bent away with respect to the shank and has an elongated hole through which a locking screw may be placed. The tibia may be compressed by means of a compression screw inserted into a longitudinal threaded bore. The tibia nail enables retrograde implantation, which has been considered to be impossible for the tibia up to now.Type: GrantFiled: May 29, 2001Date of Patent: April 15, 2003Assignee: Stryker Trauma - Selzach AGInventors: Volker Bühren, Thomas Wahl, Lukas Sutter, Andreas Bernhard, Gunther O.
