摘　　要：目的研究3.0T磁共振成像(MRI)测量腕关节不稳患者近侧列腕骨间韧带损伤腕关节角的价值。方法选取2015年1月—2017年1月在哈励逊国际和平医院经关节镜检查并初步确诊为腕关节不稳患者120例作为观察组;同时招募同期健康成年志愿者30例作为对照组。对两组受检者行高场强3.0T MRI扫描,测量舟月及月三角韧带长度、韧带宽度、韧带厚度,舟月及月三角夹角(舟月角)、头骨与月三角夹角(头月角)、桡骨与月三角夹角(桡月角)。观察并对比两组腕关节MRI检查中舟月及月三角韧带产生的信号强度。结果观察组背侧部分、掌侧部分、近侧部分舟月及月三角韧带长度均长于对照组(P<0.05)。观察组背侧部分、掌侧部分、近侧部分舟月及月三角韧带宽度均大于对照组(P<0.05)。观察组背侧部分、掌侧部分、近侧部分舟月及月三角韧带厚度均大于对照组(P<0.05)。观察组舟月角、头月角及桡月角均大于对照组(P<0.05)。对照组舟月及月三角韧带MRI信号强度为低信号,观察组舟月及月三角韧带MRI信号强度为高信号。结论 3.0T MRI对测量腕关节不稳患者近侧列腕骨间韧带损伤腕关节角具有非常好的临床价值,可有效测量不稳腕关节的MRI信号强度(舟月与月三角韧带)、舟月与月三角韧带大小、腕骨间及腕骨和桡骨的夹角等,能为手外科医师提供客观的治疗依据。Objective We aimed to investigate the value of 3.0T magnetic resonance imaging(MRI)measurements in patients with carpal instability who suffered proximal row ligament injury of the wrist joint angle.Methods This study enrolled 120 patients(study group)who underwent arthroscopic examination and were initially diagnosed with carpal instability at Harrison International Heping Hospital from January 2015 to January 2017.Thirty healthy volunteers were recruited as the control group at the same time.High field intensity 3.0T MRI scans were performed in the two groups to measure the length,width,and thickness of the scapholunate and triangular ligaments,the angle between the scapholunate and triangular ligaments(scapholunate angle),the angle between the skull and the lunotriquetral(skull angle),and the angle between the radius and the lunotriquetral(radial angle).We compared the signal strengths for the scapholunate and the triangular ligaments in MRI scans of the wrist joints in the two groups.Results The dorsal,palmar,and proximal parts of the scapholunate and triangular ligaments were all longer in the study group compared with the control group(P<0.05).Furthermore,the dorsal,palmar,and proximal parts of the scapholunate and triangular ligaments were all wider in the study group compared with the control group(P<0.05),and the dorsal,palmar,and proximal parts of the scapholunate and triangular ligaments were thicker in the study group compared with the control group(P<0.05).The scapholunate,skull,and radial angles were all higher in the study group compared with the control group(P<0.05).The scapholunate and triangular ligaments had low signals in the control group compared with the study group.Conclusion 3.0T MRI measurements demonstrate good clinical value in terms of diagnosing carpal instability in patients with proximal row carpal ligament injury of the wrist joint angle.This technique can not only measure the signal intensity of MRI instability of the wrist(scapholunate and triangular ligament),but can also meas
