摘要:

目的 探讨青少年CraigⅠ型锁骨骨折术后并发症的影响因素,分析逆行弹性钉内固定的保护效应,构建并验证术后并发症的预测模型。方法 选取180例青少年CraigⅠ型锁骨骨折患者。术后随访1年,根据其是否发生并发症分为并发症组(56例)和非并发症组(124例)。比较2组临床资料,采用多因素Logistic回归分析术后并发症的影响因素,并据此构建列线图预测模型;采用受试者工作特征(ROC)曲线评估各因素及联合模型的预测效能。结果 与非并发症组比较,并发症组术中出血量、血清N-端肽交联(NTX)水平较高,Constant-Murley肩关节评分、血清Ⅰ型原胶原N-端前肽(PⅠNP)、采用逆行弹性钉内固定的比例较低(P<0.05)。多因素Logistic回归分析显示,术中出血量高、高NTX水平是术后并发症发生的独立危险因素,而采用逆行弹性钉内固定、高Constant-Murley评分及高 PⅠNP水平则是保护因素(P<0.05)。基于此构建预测模型,该模型通过Omnibus检验(P<0.01)且拟合良好(Hosmer-Lemeshow检验,χ2=10.047,P=0.262)。ROC曲线分析显示,手术方式、术中出血量、Constant-Murley评分、PⅠNP及NTX联合预测模型的区分效能最佳,曲线下面积(AUC)为0.949(95%CI:0.914~0.984),显著高于任一单一预测因子(P<0.05),其预测敏感度和特异度分别为91.1%和87.9%。结论 构建的联合预测模型对青少年CraigⅠ型锁骨骨折术后并发症具有良好的区分度与预测效能,可为临床风险评估提供量化工具。

Abstract:

Objective To investigate the influencing factors of postoperative complications in adolescents with Craig type Ⅰ clavicle fractures, analyze the protective effect of retrograde elastic intramedullary nailing, and develop/validate a predictive model for postoperative complications. Methods A total of 180 adolescent patients with Craig type Ⅰ clavicle fractures were selected. The patients were followed up for 1 year after surgery, and they were divided into the complication group (56 cases) and the non-complication group (124 cases) based on whether complications occurred. The clinical data of the two groups were compared, and the influencing factors of postoperative complications were analyzed using multivariate Logistic regression, and a nomogram prediction model was constructed accordingly. The predictive efficacy of each factor and the combined model was evaluated using the receiver operating characteristic (ROC) curve. Results Compared with the non-complication group, the intraoperative blood loss and serum N-terminal peptide cross-linking (NTX) level were higher in the complication group, while the Constant-Murley shoulder joint score, serum type Ⅰ procollagen N-terminal propeptide (PⅠNP) and the proportion of retrograde elastic nail internal fixation were lower in the complication group (P<0.05). Multivariate Logistic regression analysis revealed that high intraoperative blood loss and high NTX level were independent risk factors for postoperative complications, while retrograde elastic nail internal fixation, high Constant-Murley score and high PⅠNP level were protective factors (P<0.05). Based on this, a predictive model was constructed. The model passed the Omnibus test (P<0.01) and fitted well (Hosmer-Lemeshow test, χ2 = 10.047, P = 0.262). ROC curve analysis showed that the combined predictive model of surgical method, intraoperative blood loss, Constant-Murley score, PⅠNP and NTX had the best discrimination efficacy, with an area under the curve (AUC) of 0.949 (95% CI: 0.914-0.984), which was significantly higher than any single predictive factor (P<0.05), and its prediction sensitivity and specificity were 91.1% and 87.9%, respectively. Conclusion The constructed combined predictive model has good discrimination and predictive efficacy for postoperative complications in adolescents with Craig type Ⅰ clavicle fractures, and can provide a quantitative tool for clinical risk assessment.
