At the first examination weshould always search for nerve the nerve is severed, it should atonce be found and the ends later, in the healing of the frac-ture the nerve becomes compressed bythe scar tissue or the callus, the indi-cations for operation are not so clear,because observations have demonstratedthat nerve function is restored laterwhen the scar tissue and callus areabsorbed. This, however, does notalways take place, and surgeons arefrequently called upon to much doubt a more carefulstudy of the cases would in many in-stances lead us to an earlier prognosis for the restoration of thefunction of the nerve after suture orafter its separation from its surroun
