研究目的:

探究严重开放性胫腓骨骨折截肢的危险因素,构建预测模型,并评估该模型的预测价值。  

Objectives of Study:

To investigate the risk factors of limb loss for severe open tibiofibular fractures, construct a predictive nomogram model and validate its prediction efficiency.

药物成份或治疗方案详述:

采用回顾性研究方法,分析2014年至2024年在无锡市第九人民医院治疗的577例开放性胫腓骨骨折患者的临床资料,所有患者均接受急诊保肢手术。依据医院信息系统收集患者的电子病历和随访数据,包括人口学资料、受伤机制、MESS评分、受伤至手术时间间隔、开放性骨折Gustilo-Anderson分型、胫骨骨折AO分型、胫神经断裂情况、合并脑外伤或胸部外伤或其他肢体损伤情况、合并症、血清乳酸值及结局指标(是否最终截肢)。根据患肢结局,将患者分为截肢组和保肢成功组。按照7:3比例将数据分为训练集和验证集,进行内部验证。采用单因素分析筛选严重开放性胫腓骨骨折保肢失败的可能危险因素,对单因素分析筛选出的因素行多因素 Logistic 回归分析,筛选严重开放性胫腓骨骨折保肢失败的独立危险因素,建立截肢风险预测模型,并构建列线图。通过受试者工作特征(ROC)曲线、C-index、Hosmer-Lemeshow拟合优度检验及临床决策曲线(DCA 曲线)验证预测模型的预测效能。 

Description for medicine or protocol of treatment in detail:

A retrospective study was conducted to analyze the clinical data of 577 patients with severe open tibiofibular fractures treated at Wuxi Ninth People's Hospital from 2014 to 2024, all of whom underwent emergency limb-salvage surgery. Patient medical records and follow-up data were collected from the hospital information system, including demographic information, injury mechanism, MESS score, time interval from injury to surgery, Gustilo-Anderson classification, AO classification of tibial fractures, tibial nerve continuity, concomitant brain injury or chest injury or other limb injuries, comorbidities, serum lactate levels, and outcome indicators (whether or not the limb was eventually amputated). Patients were divided into an amputation group and a limb preservation group based on the outcome of the affected limb. The data were divided into a modeling set and a validation set with a ratio of 7:3 randomly. Univariate analysis was used to screen the potential risk factors for amputation, which were then included in a multivariate logistic regression to identify independent risk factors for limb loss in patients with severe open tibiofibular fractures and establish a nomogram clinical predictive model. The predictive efficacy of the nomogram model was analyzed utilizing the receiver operating characteristic (ROC) curve, C-index, Hosmer-Lemeshow test, and decision curve analysis (DCA).
