急性创伤致肩袖撕裂的超声诊断

目的探讨肩袖撕裂的超声特征，评价超声检查肩袖撕裂的应用价值。方法对33例急性创伤后疑诊肩袖损伤者行超声检查，并与磁共振、肩关节造影或手术结果进行比较。结果肩袖撕裂的超声主要表现为：肩袖不显示，肩袖部分缺失，肩袖内局灶性异常回声，肩袖局部变薄。超声诊断的敏感性92％(22／24)，特异性82％(9／11)，准确性94％(31／33)。结论超声诊断肩袖撕裂有较高的应用价值，可作为急性肩部创伤而X线检查正常患者的首选检查方法。

Ultrasonography of rotator cuff tear after shoulder trauma

Objective To study the ultrasonographic characteristics of rotator cuff tear after shoulder trauma,and to evaluate the value of ultrasonography in the diagnosis of rotator cuff tear.Methods Thirty-three patients suspected as rotator cuff tear in acute injuries were detected by ultrasound.Sonographic examinations were compared with surgery,arthrography or MRI.Results Sonographic characteristics include: invisibility of the cuff,focal defect of the rotator cuff,focal abnormal echogenicity within the cuff,focal thinned cuff.The sensitivity of sonography in detecting rotator cuff tear was 92% (22/24),the specificity was 82% (9/11),and the accuracy was 94% (31/33).Conclusions Sonography is the preferred examination method in the diagnosis of rotator cuff tear.
