Systems and associated methods for repairing first and second bone fragments include a bone compression device characterized by an elongated fastener and an anchor. The fastener includes an externally-threaded shank, an enlarged head, and a bore extending through both. The anchor includes an internally-threaded bore configured to receive the threaded shank of the fastener at a first end of the anchor, and an enlarged shoulder at a second end. The fastener inserts fittedly into a first bore formed in the first and second bone fragments, with the head engaging a rim of the first bore. The anchor inserts fittedly into a second bore formed in the second bone fragment, the anchor shoulder engaging a rim of the second bore. During compression of the bone segments, a small space is maintained between the second end of the anchor and an intersection of the first bore and the second bore.
