Anatomic external fixation system for the ankle

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 feature, the first fixation component configured to support a first clamping device to secure a first bone pin inserted within a first bone extending between a foot and a knee of the lower extremity;
• and
• 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 feature configured to engage with the first engagement feature to restrict motion between the first fixation component and the second fixation component, the second fixation component configured to support a second clamping device to secure a second bone pin inserted within a second bone of the foot;
• and
• wherein the first fixation component or the second fixation component includes an extension configured to support a third clamping device to secure a third bone pin inserted within a medial or lateral surface of a heel of the foot.

• and
• 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, the second fixation component configured to support a second clamping device to secure a second bone pin inserted within a second bone of the foot;
• and
• a fastener configured to engage the first pivot structure and the second pivot structure to restrict motion between the first fixation component and the second fixation component;
• and
• a bone pin insertion opening defined through the fastener, the first pivot structure and the second pivot structure to allow a third bone pin to pass through the defined opening for insertion within a medial or lateral surface of a heel of the foot.

A surgical kit, comprising:

• a first fixation component configured to support a first clamping device to secure a first bone pin inserted within a first bone extending between a foot and a knee of a lower extremity of a subject, the first fixation component extending from a first proximal end to a first distal end;
• a second fixation component extending from a second proximal end to a second distal end and configured to be coupled to the first distal end of the first fixation component;
• a third fixation component extending from a third proximal end configured to be coupled to the second distal end of the second fixation component to a third distal end;
• an extension configured to be coupled to the third fixation component and to extend over a dorsal portion of the foot and to support a second clamping device to secure a second bone pin inserted within a dorsal surface of a second bone of the foot;
• and
• a first frame connector extending from a first proximal frame end configured to be coupled to the second fixation component to a first distal frame end, and configured to support a third clamping device to secure a third bone pin inserted within a third bone of the foot.
