Publication number: 20220142685Abstract: The invention concerns a distal radius fracture fixation device for securing at least two fractured bone segments together. The device comprises: a body portion comprising at least two insertion channels each extending through the body portion and each being configured for receiving a bone fixation element therethrough; and an insertion device connection portion connected to the body portion, and for coupling a separate insertion device to the fracture fixation device. The insertion device connection portion is arranged to be decoupled from the body portion.Type: ApplicationFiled: February 8, 2019Publication date: May 12, 2022Applicant: DISRAD AGInventors: Daniel FLURI, Silas ZURSCHMIEDE, Andreas SCHWEIZER, Ladislav NAGY

Patent number: 11051864Abstract: Intramedullary fixation assemblies (4, 8) and intramedullary fixation devices (1, 24) can be used in orthopaedic surgery for the fixation of bone fractures. Also disclosed is an insertion device (30) for inserting an intramedullary fixation device, and a method of fixing a bone fracture. The fixation devices are preferably for addressing fractures of the distal radius, and are preferably styloid nails. The styloid nails preferably have a head portion that can accept up to three bone screws; one of the bone screws is designed to extend across a fracture line between a proximal and a distal bone fragment while the other bone screws are designed to be retained in the distal bone fragment.Type: GrantFiled: March 11, 2013Date of Patent: July 6, 2021Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Andreas Appenzeller, Ladislav Nagy, Daniel Fluri, Christof Dutoit, Andre Galm

Patent number: 9351742Abstract: A drill guide includes a first bone plate that extends along a first middle plane, and a second bone plate that extends along a second middle plane. The drill guide further includes a first articulation and a second articulation that is connected to the first articulation. The first and second articulations are arranged between the first and the second bone plate. Each of the first and second articulations is releasably lockable.Type: GrantFiled: November 17, 2014Date of Patent: May 31, 2016Assignee: The University of ZurichInventors: Andreas Appenzeller, Ladislav Nagy, Andreas Schweizer, Daniel Fluri

Patent number: 9198700Abstract: A system for fixing a fracture near a joint of a bone comprises (a) an intramedullary device including a longitudinal body and a head, the longitudinal body extending from a proximal end to a distal end, the head being attached to the proximal end of the longitudinal body; and (b) a plate implantable into a head portion of the bone to provide support to a joint zone, the plate engageable with the intramedullary device. The plate is substantially U-shaped and includes a midsection and a pair of arms extending from the midsection, the pair of arms forming a space therebetween, the space sized and shaped to accommodate the head of the intramedullary device.Type: GrantFiled: March 15, 2013Date of Patent: December 1, 2015Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Andreas Appenzeller, Robert Frigg, Nicolas Bouduban, Ladislav Nagy
