Publication number: 20190150994Abstract: An orthopedic plate has a first end including a locking screw hole that receives a locking screw and spaced from that hole is a closed compression housing that extends from the bone-facing side of the plate and which receives a compression screw that forms an angle of from about 10° to about 70° with a longitudinal axis of the plate. The compression housing is not located on the medial line of the plate, but is peripheral to the medial line, either in the longitudinal or the medial direction of the plate.Type: ApplicationFiled: January 18, 2019Publication date: May 23, 2019Inventors: Derek S.

Publication number: 20190069890Abstract: A method includes forming a bone tunnel through a first bone and a second bone and inserting a flexible construct through the bone tunnel. The flexible construct includes a first anchoring element and a second anchoring element coupled by at least one flexible strand defining an adjustable loop. The at least one flexible strand includes a first end extending from the first anchoring element in an opposite direction from the adjustable loop. A length of the adjustable loop is adjusted to position the first bone and the second bone in a selected spacing. The first end of the at least one flexible strand is coupled to a tissue section using a third anchoring element.Type: ApplicationFiled: July 25, 2018Publication date: March 7, 2019Applicant: Wright Medical Technology, Inc.Inventors: Jesse G.

Publication number: 20180318097Abstract: An implant includes a curved first plate section having a curvature about a longitudinal axis extending in a longitudinal direction. The first plate section has a first hole and a second hole. The first hole and the second hole are positioned to receive respective bone screws for attaching the implant to a first curved surface of a bone having a syndesmosis. A second plate section extends continuously from the first plate section. The second plate section has at least a third hole that is positioned to be offset from the first hole and the second hole in a direction that is anterior or posterior from the first hole and the second hole in a case where the longitudinal axis is aligned along a superior-inferior direction. The third hole is configured to receive at least one screw or at least one button for holding a suture at a position offset from the first line segment hole and the second hole in the anterior or posterior direction, for reducing the syndesmosis.Type: ApplicationFiled: May 4, 2017Publication date: November 8, 2018Applicant: Wright Medical Technology, Inc.Inventors: Scott A.

Publication number: 20160354128Abstract: The invention comprises a lateral ankle fusion plate, a jig for use with the fusion plate and a method for ankle fusion of the joints between the tibia, the talus, and the calcaneus. In addition, a separate fusion screw from posterior to anterior through the calcaneal tuberosity into the distal tibia is useful and can be placed using the targeting jig of the invention. The plate includes a C-shaped stirrup portion that wraps the bottom of the calcaneus and is provided with a screw hole for a T-T-C-fusion screw. A C-shaped targeting jig is provided that interfaces with the plate to allow for placement of the calcaneal screw and has an additional attachment for placement of the independent fusion screw so as to avoid impingement with the plate, and plate screws. The invention also relates to a method of surgery that incorporates the use of the plate, the jig and the tibial/talar/calcaneal fusion screw for an arthrodesis of the ankle joint.Type: ApplicationFiled: August 15, 2016Publication date: December 8, 2016Applicant: Orthohelix Surgical Designs, Inc.Inventors: Clifford L. Jeng, Jackson R. Heavener, Mark Myerson, Bryan D. Den Hartog, Thomas San Giovanni
