The results of using rigid fixation for 75 mandibular fractures in 52 patients and allowing immediate function were retrospectively analyzed. Sixteen percent of fractures developed postoperative infection. All infections were in fractures associated with teeth; none occurred in fractures fixed within 24 hours of injury. Angle and posterior body fractures were most likely to become infected. Fractures with improperly applied rigid fixation also were subject to a high infection rate. It was unusual for infection involving this type of treatment to prolong the course of therapy or affect the final outcome.
对52例患者的75处下颌骨骨折采用坚固内固定并允许即刻功能恢复的结果进行了回顾性分析。16%的骨折发生了术后感染。所有感染均发生在与牙齿相关的骨折中；受伤后24小时内固定的骨折未发生感染。角部和下颌骨后部骨折最易发生感染。坚固内固定应用不当的骨折感染率也较高。这种治疗方式引起的感染延长治疗过程或影响最终结果的情况并不常见。
