1. A system for preventing relative motion between bones or sections of bone, the system comprising:
an insertion tool comprising a handle, a driver coupled to the handle, a tool shaft extending from the handle and comprising a first engagement feature, and a drive shaft disposed within the tool shaft and operably coupled to the driver, wherein the drive shaft comprises a drive feature; and
an implant removably coupled to the insertion tool and comprising a trunk, a distal anchor, a proximal anchor, a skirt defining a cavity and comprising a second engagement feature configured to be engaged by the first engagement feature of the tool shaft to prevent relative rotation between the implant and the insertion tool, and a stem disposed within the cavity and coupled to a proximal end of the trunk that is at an axial position distal to the proximal anchor, wherein the stem comprises a driven feature configured to be engaged by the drive feature of the drive shaft,
wherein the driver is configured to receive an input for the drive shaft to draw the stem proximally such that the trunk is drawn towards the insertion tool, and wherein the drawing of the trunk and engagement of the first and second engagement features is configured to deploy the proximal anchor outwardly.
