摘　　要：目的了解无症状青年人下尺桡关节积液与三角纤维软骨完整性的关系。方法对2014年9月至2019年10月北京积水潭医院放射科招募的无腕关节疼痛症状、外伤和手术史、畸形及肿物的32名青年志愿者的腕关节磁共振成像(MRI)检查影像资料,进行回顾性阅读并分析,以质子密度加权脂肪抑制序列显示下尺桡关节内液性高信号为判断有下尺桡关节积液的标准,观察是否存在下尺桡关节积液、积液的形态及三角纤维软骨(TFC)是否存在异常。结果32名青年无症状者平均年龄25(20~30)岁,其中男性22名、女性10名。共有25名(78.1%)腕关节有下尺桡关节积液,其中21名(84.0%)为线状/管状,4名(16.0%)为囊状;男性15名(62.8%)、女性10名(10/10)。25名有下尺桡关节积液者中,TFC完整者20名(62.5%),其中17名积液局限于下尺桡关节近端,3例积液达TFC下表面;TFC撕裂者5名(15.6%),其中4名下尺桡关节积液达TFC的下表面。有尺骨中性、正性和负性变异者分别为23(71.9%)、6和3名,有下尺桡关节积液者分别为17、5和3名,TFC撕裂者分别为1、4和0名,不同性别间和尺骨变异状态下尺桡关节积液发生情况差异均无统计学意义(P=0.069,P=0.702)。结论无症状青年人存在下尺桡关节积液情况,少部分下尺桡关节积液合并TFC撕裂。Objective To study the relationship between distal radioulnar joint(DRUJ)effusion and the integrity of triangular fibrcarotilage(TFC)in asymptomatic young adults.Methods Thirty two asymptomatic young adults,22 males and 10 females with a mean age of 25 year(20-30)were recruited in the study between September 2014 and October 2019.All subjects had no wrist pain,no wrist deformity or wrist mass,and had no history of wrist trauma or surgery.The DRUJ effusion was definedasfluid-like high signal intensityon fatsuppression proton density-weighted MRI.The presence of distal radioulnar joint effusion,the shape of the effusion,and the presence of triangular fibrocartilage abnormalities were documented.Results Among 32 subjects,25(78.1%,15 males and 10 females)presented with distal radioulnar joint effusion on wrist MR images,including linear/tubular in 21 cases(84.0%)and saccular in 4 cases(16.0%).Twenty cases(62.5%)had distal radioulnar joint effusion while the TFC was intact,among whom,the effusion was confined to the proximal side of distal radioulnar jointin 17 cases,and reached the lower surface of TFC in 3 cases.In 5 cases(15.6%)with TFC tear,the effusion reached the lower surface of TFC in 4 cases.There were neutral,positive and negative variations of the ulna in 23,6 and 3 cases,respectively,among whomthe distal radioulnar effusion was presented in 17,5,3 cases,and TFC tear in 1,4 and 0 cases,respectively.The presence of distal radioulnar effusion was not significantly correlated with genders(P=0.069)or types of ulna variance(P=0.702).Conclusion The distal radioulnar joint effusion maybe resent in asymptomatic young adults,and it maybe complicated with TFC tear.
