Abstract

A system includes a first fixation component, a second fixation component, and a first fastener. The first fixation component includes a first pivot structure including a first engagement surface and a first engagement feature, and can support one or more first clamping devices that secure bone pins inserted within a first bone. The second fixation component includes a second pivot structure including a second engagement surface configured to engage the first engagement surface, and is configured to support one or more second clamping devices that secure bone pins inserted within a second bone. The first fastener is configured to couple the first pivot structure to the second pivot structure and includes a first fastening element including a second engagement feature configured to engage the first engagement feature to maintain a first angle between a first axis of the first fixation element and a second axis of the second fixation element.

Dependent claims

An external fixator system comprising:

a first fixation component extending between a first proximal end portion and a first distal end portion of the first fixation component, the first fixation component including a first pivot structure including a first engagement surface and a first engagement feature, the first fixation component configured to support one or more first clamping devices that secure bone pins inserted within a first bone connected to a joint of a subject;
a second fixation component extending between a second proximal end portion and a second distal end portion of the second fixation component, the second fixation component including a second pivot structure including a second engagement surface configured to frictionally engage with the first engagement surface of the first fixation component, the second fixation component configured to support one or more second clamping devices that secure bone pins inserted within a second bone connected to the joint of the subject;
and
a first fastener configured to couple the first pivot structure to the second pivot structure and including a first fastening element that comprises a second engagement feature configured to engage the first engagement feature of the first pivot structure to maintain a first angle between a first longitudinal axis extending between the first proximal end portion and the first distal end portion of the first fixation component and a second longitudinal axis extending between the second proximal end portion and the second distal end portion of the second fixation component.

A surgical kit comprising:

a first proximal end portion configured to support one or more first clamping devices that secure bone pins inserted within a first bone connected to a joint of the subject;
a first distal end portion configured to be coupled to the first proximal end portion, the first distal end portion including a first pivot structure including a first engagement surface and a first engagement feature;
a second proximal end portion configured to support one or more second clamping devices that secure bone pins inserted within a second bone connected to the joint of the subject;
a second distal end portion configured to be coupled to the second proximal end portion and including a second pivot structure including a second engagement surface configured to frictionally engage with the first engagement surface of the first fixation component;
and
a first fastener configured to couple the first pivot structure to the second pivot structure, the first fastener including a first fastening element that includes a second engagement feature configured to engage the first engagement feature of the first pivot structure to maintain a first angle between a first longitudinal axis extending along the first proximal end portion and the first distal end portion when the first proximal end portion is coupled to the first distal end portion, and a second longitudinal axis extending along the second proximal end portion and the second distal end portion when the second proximal end portion is coupled to the second distal end portion.
