| 目的 探讨超声定量评估肱骨结节间沟解剖结构的准确性及可重复性。方法 回顾性分析42例行肩部超声检查患者的临床及影像学资料，19例于超声检查后1个月内再次接受CT检查，23例再次接受超声复诊。测量结节间沟的宽度、深度、开放角及内侧角。比较超声与CT、超声首诊与复诊所测数值的差异，计算组内相关系数（ICC）及变异系数（CV），并评估2次超声检查的可重复性。结果 超声与CT测量结节间沟各参数差异均无统计学意义（P均>0.05）；2种方法测量结节间沟宽度、深度、内侧角的一致性中等（ICC=0.79、0.68、0.73），测量开放角的一致性良好（ICC=0.94），CV为5.78%~9.64%。超声首诊与复诊所测各参数差异均无统计学意义（P均>0.05）；测量结节间沟宽度、深度的一致性中等（ICC=0.65、0.74），测量开放角、内侧角的一致性良好（ICC=0.98、0.94），CV为3.61%~11.47%。Bland-Altman图显示95.65%（22/23）的数据点位于一致性界限内。结论 超声测量结节间沟解剖参数的准确性及可重复性较好，可用于定量评估结节间沟形态。 |

| Objective To investigate the accuracy and repeatability of ultrasound in quantitative evaluation of intertubercular groove of humerus. Methods Clinical and imaging data of intertubercular groove of humerus in 42 patients were retrospectively analyzed. Nineteen patients underwent CT examination, and 23 patients underwent ultrasound again within 1 month after the first ultrasound examination. The width, depth, opening angle and medial wall angle of intertubercular groove of humerus were measured and compared between two imaging methods and between two times of ultrasonography. Intraclass correlation coefficient (ICC) and coefficient of variation (CV) were also calculated. The repeatability of the first and second ultrasonography was evaluated. Results The measurements of intertubercular groove of humerus demonstrated no statistically significant difference between ultrasonography and CT (all P>0.05). The consistency of width, depth and medial wall angle between ultrasonography and CT was medium (ICC=0.79, 0.68, 0.73), while opening angle was good (ICC=0.94). CV ranged from 5.78% to 9.64%. The measurements of intertubercular groove of humerus showed no significant difference between the first and second ultrasonography (all P>0.05). The consistency of width and depth was medium (ICC=0.65, 0.74), while the opening angle and medial wall angle were good (ICC=0.98, 0.94). CV ranged from 3.61% to 11.47%. Bland-Altman plots showed that 95.65% (22/23) of the measurements were within the consistency limit. Conclusion Ultrasonography shows good accuracy and repeatability in measuring the intertubercular groove of humerus. |
