To determine the value of the sonographic subluxation test--dynamic scanning of a shoulder during maximal external rotation--in the evaluation of medial displacement of the biceps tendon.
The subluxation test was performed during shoulder sonography in 1,210 patients, 284 of whom subsequently underwent surgery (152 men and 132 women aged 24-77 years [mean, 52 years]). Subluxation or displacement of the biceps tendon was surgically confirmed in 21 of the 284 patients (16 men and five women aged 35-57 years [mean, 48 years]). The sonographic and surgical findings in these 21 patients were analyzed.
The subluxation test helped detect 12 of 14 (86%) cases of subluxation. Static scanning (without the subluxation test) depicted six of seven (86%) cases of dislocation. The test failed or could not be performed in 18 of the 284 (6%) patients; however, no false-positive findings occurred.
The subluxation test is reliable in the diagnosis of subluxation of the biceps tendon and should be performed during shoulder sonography.
确定超声下半脱位试验——在最大外旋时对肩部进行动态扫描——在评估肱二头肌腱内侧移位中的价值。
对1210例患者进行肩部超声检查时进行半脱位试验，其中284例随后接受了手术（152例男性和132例女性，年龄24 - 77岁[平均52岁]）。284例患者中有21例（16例男性和5例女性，年龄35 - 57岁[平均48岁]）经手术证实存在肱二头肌腱半脱位或移位。对这21例患者的超声和手术结果进行了分析。
半脱位试验有助于检测出14例半脱位病例中的12例（86%）。静态扫描（无半脱位试验）显示7例脱位病例中的6例（86%）。284例患者中有18例（6%）试验失败或无法进行；然而，未出现假阳性结果。
半脱位试验在诊断肱二头肌腱半脱位方面可靠，应在肩部超声检查时进行。
