Abstract：
Scapholunate ligament lesion is the most common ligament lesion in the wrist. We assessed the reliability of sonography in detecting it during Watson test. Twenty patients with scapholunate ligament lesion confirmed on MRI and intraoperatively were assessed preoperatively between July 2020 and April 2023. Sonography was performed on the scaphoid dorsal subluxation in wrist neutral and during Watson test and compared with the healthy contralateral side. Dorsal subluxation was measured by two independent investigators and intra- and inter-observer reliability were assessed. We found a significant difference between dorsal subluxation of the scaphoid in the healthy (0.89 mm, SD 0.67 mm) compared to the pathological side (1.67 mm, SD 0.95 mm). Reliability was very good and the standard error of measurement was less than 0.4 mm for all measurements. Sonography during Watson test demonstrated high reliability in diagnosing scapholunate lesions. LEVEL OF EVIDENCE: III.
摘要：
肩胛骨韧带病变是腕部最常见的韧带病变。我们评估了在Watson测试过程中超声检查的可靠性。在2020年7月至2023年4月期间，对20例经MRI和术中证实为肩胛骨韧带病变的患者进行了术前评估。在手腕中性和Watson测试期间，对舟骨背侧半脱位进行了超声检查，并与健康的对侧进行了比较。由两名独立的研究者测量背部半脱位，并评估观察者内部和观察者之间的可靠性。我们发现健康的舟骨背侧半脱位之间存在显着差异（0.89毫米，SD0.67mm）与病理侧（1.67mm，SD0.95毫米）。可靠性非常好,并且对于所有测量,测量的标准误差小于0.4mm。Watson测试期间的超声检查在诊断肩胛骨病变方面具有很高的可靠性。证据级别：III.
