A compression device may include, but is not limited to, a threaded body, a sliding element, and a compression element connecting the threaded body and the sliding element. According to one embodiment, upon implantation, the threaded body contacts a first bony fragment and the sliding element contacts to a second bony fragment. In at least one embodiment, upon being engaged, the compression element applies sustained tension to the sliding element and opposing tension to the threaded body, thereby compressing the first bony fragment and the second bony fragment along a plane of contact promoting healing.
