  • Publication number: 20190150994
    Abstract: 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.

  • Publication number: 20190125418
    Abstract: An implant comprises a unitary body including an intramedullary portion connected to an extramedullary portion. The unitary body is configured to attach a first bone section to a second bone section. The intramedullary portion has a first longitudinal axis, and is configured for insertion into the first bone section. The intramedullary portion includes at least one first fastener aperture having an aperture axis oriented obliquely relative to the first longitudinal axis. The extramedullary portion is configured to abut a surface of the second bone section and includes at least one second fastener aperture disposed to transversely receive a bone fastener inserted in the second bone section. The extramedullary portion has a second longitudinal axis offset from, the first longitudinal axis.

  • Publication number: 20190069890
    Abstract: 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.

  • Publication number: 20180318097
    Abstract: 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.

  • Patent number: 9597131
    Abstract: This invention provides a calcaneal plate implanted using a sinus tarsi approach and comprises an anterior section having two locking screw holes, an s-shaped posterior facet section having a four locking holes and which rounds toward the bone at both the inferior and superior edges and is reinforced at the superior edge, and a blade shaped posterior portion having three linearly aligned locking holes and terminating in a tapered portion. There is also, a drill guide assembly having a drill guide column inserted through a hole in a targeting guide and locking to one of the locking holes in the plate, and cannulated drill guide sleeves that lock into holes in the targeting guide in a spaced relation whereby when the targeting guide is locked into the plate, the targeting guide can be used as a handle and wherein locking screws can be implanted percutaneously.

  • Publication number: 20160354128
    Abstract: 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.

  • Patent number: 9144443
    Abstract: The present invention relates to a series of orthopedic plates for use in repair of a clavicle. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and wither one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.
