1. An implant for use between two bone segments, the implant comprising:
a body extending in a plane defined by a length and a width, the body having
a first connection end and a second connection end, each configured to connect to a respective bone segment, wherein the first connection end defines at least one connection hole configured to receive a pivot fastener to form a rotational joint with the fastener, and
a deformable portion operable to respond to a rotation at the first connection end about an axis transverse to the length,
wherein the deformable portion, responsive to the rotation, is configured to deform to cause a displacement of the connection ends relative to one another along the length within the plane, and
wherein the displacement results in an increase in separation between the connection ends.
