Publication number: 20150073415Abstract: A method for implanting a longitudinal intramedullary nail into the tibia comprises inserting the tibia nail along a plane of symmetry through the tuberositas tibiae. Thereby, the tuberositas tibiae can be used during nail insertion to correctly align the nail and the target arm to the symmetry plane of the bone. This means, that the whole construct, the nail attached to the target arm, has to be inserted in external rotation.Type: ApplicationFiled: November 18, 2014Publication date: March 12, 2015Inventors: Annika Homeier, Ilan Howling, Nils Zander, Lothar Kühne, Claudia Graca

Publication number: 20140214094Abstract: A system and method of angularly stable fixation of an implant on a bone includes the steps of making at least one hole in the bone by means of a bone drill. An implant is placed on the bone in a desired position and joining the implant with the bone, such that the implant is prevented from rotation about its attachment point. A system is provided for use in the above described method. The system comprises a bone drill, an implant and a sonotrode for angularly stable fixation of the implant on the bone. The system can further comprise a joining element to join the implant with the bone.Type: ApplicationFiled: March 19, 2014Publication date: July 31, 2014Applicant: Stryker Trauma GmbHInventors: Robert Sonntag, Klaus Dorawa, Nils Zander, Jörg Mayer, Urs Weber, Andrea Müller

Patent number: 7981114Abstract: A device for installation of a guide wire for a drilling tool in a correct positional arrangement in a bone. The device includes a tissue protection sleeve, which has at one end a laterally projecting grip or handle. A trocar is provided, which trocar can be introduced into the tissue protection sleeve from the handle end and whose other end is closed. The trocar is rotatable in the tissue protection sleeve and has a central bore hole and a plurality of eccentric axially parallel bore holes, through which a guide wire can be passed. A second handle is provided which extends approximately in the same direction of the first handle and whose one end engages the end of the trocar situated the outside of the tissue protection sleeve, so that the normally freely rotatable trocar is fixed in the direction of rotation relative to the tissue protection sleeve, when both handles are manually clamped against each other.Type: GrantFiled: December 3, 2007Date of Patent: July 19, 2011Assignee: Stryker Trauma GmbHInventor: Nils Zander
