One hundred and two consecutive open fractures of the tibial shaft were treated from 1970 to 1976. Four required primary amputation. The remainder received standardized wound care, consisting of surgical débridement and delayed primary wound closure. Soft-tissue injuries were classified according to severity, because the initial injury was the most important prognostic factor. All patients received a seventy-two-hour course of parenteral antibiotics. Fifty-six fractures were managed with cast immobilization, thirty-five with rigid internal fixation, and seven with rigid external pin fixation. The over-all rates of infection (15 per cent) and delayed union (13 per cent) are not directly comparable to other series because one must consider the severity of each injury when analyzing results. Management of the fracture itself should be individualized. The risk of primary wound closure does not appear to be warranted.
