A bone fixation system includes at least one bone fixation member (24) and a bone fixation instrument (22). The bone fixation member includes a strap (32) and a locking mechanism (38). The strap can be pulled through the locking mechanism so as to form a loop (55) about a target bone so as to secure first and second bone segments in an approximated, compressed configuration. The bone fixation instrument is configured to apply tension to the loop about the target bone. The fixation instrument includes a tension assembly (70) that is configured to secure a free end of the bone fixation member to the fixation instrument. The tension assembly is further configured to pull the free end so as to increase tension in the loop while the tension in the loop is less than a select tension.
