Results Of the 5 cases of internal fixation failure,2 were caused by operative mistakes, 1 by wrong selection of internal fixators, 1 by too early weight-bearing,and 2 by postoperative infection;of the 11 cases of nonunion or delayed union, 5were caused by severe primary injury, and 4 by unsuccessful reduction.1 cases of pain were caused by evection of proximal LISS plate,and 1 postoperative infection due to improper emplacement of the plate during the operation resulted in long exposure of plate end.

结果：5例内固定物失效的病例中，2例由于手术操作失误，1例由于内固定物选择失误，1例由于术后负重过早，1例由于术后感染导致内固定物失效；11例骨折不愈合或延迟愈合的患者中，5例由于原始损伤严重，4例由于术中复位不佳引起不愈合或延迟愈合；1例LISS钢板近端突起于皮下引起疼痛，术后伤口感染，1例钢板近端长期外露，是由于术中钢板的放置位置不良；膝外翻畸形1例。

Moreover, this article offers various improvement programs for smoke evacuation system in subways system. Initially, we offer an idea to minimize the anti-smoke divisions and to rearrange vent positions to resolve the failure of station smoke evacuation mode. In the study of smoke evacuation process at tunnel track area, we find an upward slope will block smoke evacuation. This study also finds that start of fans operation will speed up the accumulation of smoke and endanger people's life during escape. The way to resolve is that we need to add fans at upward slope. This result is different from the report of one dimensional SES simulate analysis. To timely correct the safety evaluation result in SES report and to efficiently improve the failure of smoke evacuation system design are recommended by this article. Therefore, an increase of time for people to escape in fire hazard with less casualty.

本文另於对捷运排烟系统提出各项改善方案中，初步提出车站排烟系统防烟区划缩小构想，并配合风口位置调整策略来解决失效的车站排烟模式；而隧道轨道区排烟系统在研究过程发现爬坡段有阻碍排烟效果，本研究发现风机开启后反而加速烟气滞留并危害人员逃生，解决之道则必需於爬坡段增加风机来排除，此与一维式SES模拟分析报告结果不同，故能藉以及时更正SES报告之安全评估结果，经由所提改善方案，有效改善所发现排烟系统设计之失效，提高人员火灾时逃生的安全时间，降低人员伤亡。
