Open tibial fractures result in high rates of complications. This study aims to elucidate the risk factors causing these complications, and suggest antimicrobial regimens based on the organisms grown in post-operative infections. Over a period of five years, 173 patients had sustained open tibial fractures and undergone operative treatment at a single institution. All surgical data was gathered retrospectively through online medical records. Thirty-one patients (17.9%) had sustained post-operative bony complications, while infective complications were reported in 37 patients (21.4%). Patients with Gustilo type III fractures were found to be more than three times as likely to sustain post-operative infective (p=0.007) or bony (p=0.015) complications, compared to Gustilo type I or II fractures. The fracture location and time taken to fixation did not significantly affect the complication rate, but results were trending towards significance. The commonest cause of infective complications were hospital-acquired organisms, such as Methicillin-resistant staphylococcus aureus (40.5%). Closer monitoring of patients sustaining high grade Gustilo open fractures, as well as antimicrobial prophylaxis for both hospital-acquired organisms and environmental contaminants, will result in the best outcome for patients. Further studies with larger sample sizes are warranted, to determine the significance of fracture location and time taken to fixation on complication rates.
开放性胫骨骨折会导致较高的并发症发生率。本研究旨在阐明引发这些并发症的危险因素,并根据术后感染中培养出的微生物提出抗菌方案。在五年时间里,173例患者发生了开放性胫骨骨折并在单一机构接受了手术治疗。所有手术数据均通过在线病历进行回顾性收集。31例患者(17.9%)出现了术后骨并发症,37例患者(21.4%)报告有感染性并发症。与 Gustilo I 型或 II 型骨折相比,Gustilo III 型骨折患者术后发生感染性(p = 0.007)或骨(p = 0.015)并发症的可能性高出三倍多。骨折部位和固定所需时间对并发症发生率没有显著影响,但结果有趋于显著的趋势。感染性并发症最常见的原因是医院获得性微生物,如耐甲氧西林金黄色葡萄球菌(40.5%)。对发生高级别 Gustilo 开放性骨折的患者进行密切监测,以及对医院获得性微生物和环境污染物进行抗菌预防,将为患者带来最佳预后。有必要进行更大样本量的进一步研究,以确定骨折部位和固定所需时间对并发症发生率的影响。
