摘　　要：目的探讨斜冠状位喙肱韧带(CHL)磁共振影像对冻结肩的诊断价值。方法正常健康志愿者60例作为对照组,男、女各30例,共120侧肩,平均年龄50.5岁。72例冻结肩患者作为FS组,72例72侧肩,其中男22例,女50例、平均年龄53.5岁。肩关节磁共振扫描并测量CHL厚度,进行统计学处理。结果 CHL显示率:FS组斜冠状位CHL显示率87.5%(63/72)和对照组86.7%(104/120)比较,差异无统计学意义(P>0.05)。FS组轴位CHL显示率19.4%(14/72)和对照组24.2%(29/120)比较,差异无统计学意义(P>0.05)。CHL厚度测量:FS斜冠状位(n=63)CHL厚度(4.37±1.71)mm与对照组斜冠状位(n=104)CHL厚度(2.84±0.79)mm比较,差异有统计学意义(P<0.001)。FS组轴位(n=14)CHL厚度(3.93±1.49)mm,与对照组轴位(n=29)CHL厚度(2.29±0.65)mm比较,差异有统计学意义(P<0.001)。结论冻结肩CHL增厚,斜冠状位CHL厚度均值4.37 mm,提示冻结肩。Objective To evaluate the diagnosis of frozen shoulder with the coracohumeral ligament on the coronal oblique plane with MRI. Methods There were 60 patients（ 120 shoulder joints） in control group,with 30 males and 30 females,the mean age was 50. 5 years old. There were 72 shoulder joints in 72 patients of frozen shoulder group（ 50 femles and 22 males with a mean age of 53. 5 years） with clinical evidence and MR imaging evidence of frozen shoulder. These were prospectively analyzed to identify the CHL visualization rate and measure the maximum thickness of the CHL. Results The CHL visualization rate on the coronal oblique plane in the control group was 86. 7%（ 104 /120）,and the frozen shoulder group was 87. 5%（ 63 /72）,the difference was not significant（ P〈0. 05）. The CHL visualization rate on the axial view in the frozen shoulder group was 19. 4%（ 14 /72） and the control group was 24. 2%（ 29 /120）,the difference was not significant（ P〈0. 05）. The CHL thickness on the coronal oblique plane（ n = 63） in the patients with frozen shoulder was（ 4. 37 ± 1. 71） mm,which was significantly greater than（ 2. 84 ± 0. 79） mm ofpatients in the control group（ n = 104）,the difference was significant（ P〈0. 001）.The CHL thickness on the axial plane（ n = 14） in the patients with frozen shoulder was（ 3. 93 ± 1. 49） mm,which was significantly greater than（ 2. 29 ± 0. 65） mm of patients in the control group（ n = 29）,the difference was significant（ P〈0. 001）. Conclusion A thickened CHL is highly suggestive of frozen shoulder,which is 4. 37 mm on the coronal oblique plane.
