目的探讨老年全膝关节置换术(TKA)后股骨假体周围骨折(PFF)的危险因素并构建预测模型,为临床术后PFF的预防提供参考。方法回顾性分析2016年10月至2021年10月空军军医大学第一附属医院骨科收治的537例行TKA治疗的老年患者的临床资料。统计随访期间PFF的发生情况,收集临床资料。二元Logistic回归分析老年TKA后PFF的危险因素,基于危险因素构建老年TKA后PFF的预测模型。受试者工作特征(ROC)曲线和Hosmer-Lemeshow(H-L)检验预测模型的区分度和校准度。结果患者出院后随访12~72个月,中位时间47个月。随访期间31例(5.77%)患者发生PFF。年龄、骨质疏松、帕金森病、股骨前切迹(AFN)是老年TKA后PFF的危险因素(P0.05);ROC曲线分析显示,老年TKA后PFF的风险预测模型具有较高的区分度(曲线下面积为0.858,95%CI:0.826~0.887),敏感度为83.87%,特异度为88.34%。结论老年TKA后PFF的发生风险较大,应针对高危因素进行防范,根据高危因素建立的预测模型具有较好的预测效能。

6号染色体长臂近端缺失是一种罕见的染色体疾病,常表现为智力低下、发育迟缓和特殊面容等异常。回顾性分析1例多发畸形胎儿的遗传学病因。该病例于2022年12月13日(孕21+1周)因超声提示胎儿多发畸形、无创产前筛查(noninvasive prenatal testing,NIPT)提示胎儿6号染色体异常高风险而行羊膜腔穿刺术,进行常规G显带染色体核型分析和拷贝数变异测序(copy number variation sequencing,CNV-seq),同时对其父母的染色体核型进行检测。羊水常规G显带染色体核型分析示:46,XX,del(6)(q14q16);羊水CNV-seq结果示:6q14.1q16.3(80960000-104640000)区存在23.68 Mb的缺失。综合上述结果考虑该缺失是造成胎儿多发畸形的原因。CNV-seq有利于确定胎儿染色体异常的断裂点,为预测胎儿发生畸形的风险及后续的遗传咨询提供依据,同时丰富了6号染色体长臂近端缺失的产前临床表型谱。
