1. A bone plug compression instrument for reshaping a bone plug, the bone plug compression instrument comprising:
a first compression element comprising a first cavity comprising a first compression surface;
a second compression element comprising a second cavity comprising a second compression surface; and
a base portion for supporting the first compression element and the second compression element,
wherein:
the second compression element is configured to move relative to the first compression element between a first position and a second, different position,
in the first position, the bone plug compression instrument forms an open configuration, in which the first and second cavities are spaced apart from each other allowing the bone plug in a substantially uncompressed state to be inserted in a space between the first and second compression surfaces, and
in the second position, the bone plug compression instrument forms a closed configuration, in which the first and second cavities form a combined cavity for compressing the bone plug received in the combined cavity, and wherein the combined cavity has at least a partially converging shape,
wherein the base portion comprises a first guide element, and the second compression element comprises a second guide element configured to engage with the first guide element such that the second compression element is configured to slidingly engage the first guide element such that a sliding movement of the second compression element with respect to the first guide element enables the second compression element to move at least from the first position to the second position, and wherein the bone plug compression instrument comprises a first lever arm pivotably connected to the second compression element by a first connection mechanism such that when the first lever arm is in an elevated position with respect to the base portion, the bone plug compression instrument is in the open configuration, and when the first lever arm is in an opposite, non-elevated position with respect to the base portion, the bone plug compression instrument is in the closed configuration.
