  • Publication number: 20200297502
    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: 10736678
    Abstract: A compression plate kit that allows for manual compression of a bone discontinuity includes a bone plate, two or more reduction screws, and a compression clamp. The compression clamp can include engagement members configured to engage the reduction screws, thereby allowing a practitioner to compress a bone discontinuity by manually closing the compression clamp. One or more implementations of a kit of the present invention can provide a practitioner with physical or tactile feedback during the compression of a bone discontinuity, and thus, provide the practitioner with the ability to better control the compression and spacing of bone portions during a reduction.
