Abstract
A modular bone fixation linkage includes a plurality of interconnected links that can angulate with respect to an adjacent one of the links about at least one axis, such as three axes. The links can further include fixation holes that are configured to receive bone anchors that secure the links to an underlying anatomical structure.
Claims20
A bone fixation linkage comprising:
- first and second links configured to interconnect with one another, each link defining a first surface configured to face a bone to which the bone fixation linkage is configured to be attached, a second surface opposite the first surface along a first direction, a first attachment member, and a second attachment member spaced from the first attachment member along a second direction, perpendicular to the first direction,
- wherein the first attachment member of each link defines a first geometry at the first surface of the link, the second attachment member of each link defines a second geometry at the second surface of the link, and the first geometry of the first link is configured to interlock with the second geometry of the second link to prevent relative angulation between the first and second links.
A bone fixation system comprising:
- first and second links configured to interconnect with one another, each link defining a first surface configured to face a bone to which the bone fixation linkage is configured to be attached, a second surface opposite the first surface along a first direction, a first attachment member, a second attachment member spaced from the first attachment member along a second direction that is perpendicular to the first direction, and first and second fixation holes that extends through the first and second attachment members, respectively, the first and second fixation holes configured to receive at least one bone anchor,
- wherein the first attachment member of each link defines a first geometry at the first surface of the link, the second attachment member of each link defines a second geometry at the second surface of the link, and the first geometry of the first link is configured to interlock with the second geometry of the second link to prevent relative angulation between the first and second links.
A method of constructing a bone fixation linkage, the method comprising:
- positioning a first link of the bone fixation linkage adjacent bone such that a first surface of the first link faces the bone, a second surface of the first link is opposite the first surface along a first direction, and a first attachment member of the first link is spaced from a second attachment member of the first link along a second direction that is perpendicular to the first direction;
- positioning a second link of the bone fixation linkage adjacent the bone such that a first surface of the second link faces the bone, a second surface of the second link is opposite the first surface along the first direction, and a first attachment member of the second link is spaced from a second attachment member of the second link along the second direction;
- and
- interlocking a first geometry of the first attachment member of the first link defined at the second surface of the first link with a second geometry of the second attachment member of the second link defined at the first surface of the second link so as to prevent relative angulation between the first and second links.
