Dynamic syndesmosis implant systems and methods

An implant system for dynamic stabilization of bones and/or tissue, comprising:

• a dynamic bone anchor;
• and
• at least one tether extending through and between the dynamic bone anchor and at least one secondary tether anchor,
• wherein the dynamic bone anchor comprises:
• a cannulated main body comprising:
• a proximal head portion, a distal end portion and a body portion extending between the proximal head portion and the distal end portion;
• a piston member positioned within the cannulation of the main body;
• and
• a resilient bumper positioned within cannulation of the body portion between at least a portion of the bumper and a retaining feature within the cannulation of the body portion,
• wherein the body portion comprises bone engagement projections extending about outer sides thereof,
• wherein the body portion comprises an outer groove extending through the bone engagement projections,
• wherein the piston member comprises a first lateral through hole, and the distal end portion comprises a second lateral through hole that is in communication with the first lateral through hole, and
• wherein the body portion comprises a lateral aperture that is in communication with the cannulation thereof and is substantially aligned with the outer groove.
