Patent number: 10905483Abstract: The invention relates to a bone screw and a method for locking a bone screw into a bore. The bore can be provided in e.g. an implant, a plate, a nail or the like. The bone screw comprises a head portion with a first axis, a proximal shaft portion with a second axis, and a distal shaft portion with a third axis. The first axis is a center axis extending in a longitudinal direction of the head portion, the second axis is a center axis extending in a longitudinal direction of the proximal shaft portion, and the third axis is a center axis extending in a longitudinal direction of the distal shaft portion. The first and third axes are aligned to each other. The second axis is displaced relative to the first and third axes.Type: GrantFiled: December 5, 2018Date of Patent: February 2, 2021Assignee: Stryker European Holdings I, LLCInventors: Nils Zander, Claudia Graca

Publication number: 20190133661Abstract: The invention relates to a bone screw system, an implant system and a method of locking a bone screw system into a bore. The bone screw system comprises a bone screw and a washer. The screw comprises a screw head and a screw shaft. The washer comprises a washer bore. A diameter of the washer bore is larger than an outer diameter of the screw shaft. This allows a displacement of the screw shaft within the washer bore. The diameter of the washer bore is smaller than an outer diameter of the screw head. This prevents the screw head from moving through the washer bore. The screw and the washer comprise each an engagement portion for an engagement with each other. At least one of these engagement portions comprises an inclined surface. The inclined surface is configured to force the screw shaft sideward upon screwing in of the screw so that a longitudinal axis of the screw is tilted relative to the axis of the washer bore.Type: ApplicationFiled: June 9, 2016Publication date: May 9, 2019Inventors: Nils Zander, Claudia Graca

Patent number: 9545273Abstract: An intramedullary nail according to the invention has a locking hole arrangement having one first opening on one side of the intramedullary nail and one second opening at an opposing side of the intramedullary nail. The locking hole arrangement has a first bore having a first bore axis and a second bore having a second bore axis. The first bore and the second bore each having a first orifice on one side of the intramedullary nail and each having a second orifice at an opposite side of the intramedullary nail. The first bore axis and the second bore axis are inclined with respect to each other and the first bore and the second bore intersect each other within the intramedullary nail.Type: GrantFiled: September 16, 2011Date of Patent: January 17, 2017Assignee: Stryker European Holdings I, LLCInventors: Ilan Howling, Claudia Graca, Annika Homeier

Patent number: 9427267Abstract: 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: GrantFiled: November 18, 2014Date of Patent: August 30, 2016Assignee: Stryker European Holdings I, LLCInventors: Annika Homeier, Ilan Howling, Nils Zander, Lothar Kühne, Claudia Graca
