高频超声诊断外伤后肢体软组织急性损伤

High frequency ultrasound in diagnosis of acute extremity soft tissue injuries after trauma

目的应用高频超声观察外伤后肢体软组织急性损伤的特征,并评价其诊断价值。方法对103例外伤后3周内肢体肿胀、疼痛的患者行高频超声检查。结果103例患者中肌肉撕裂34例,肌腱断裂6例,关节腔积血19例,韧带损伤10例,肌间血肿17例,骨化性肌炎6例,异物11例。97例116处出现皮下组织增厚、肌肉水肿,回声紊乱。结论高频超声可作为外伤后肢体软组织急性损伤后便捷的、可动态应用的首选影像学检查方法。

Objective To observe the frequency ultrasound features of acute extremity soft tissue injuries after trauma, and to evaluate its diagnostic value. Methods Totally 103 patients with limb swelling and pain within 3 weeks after trauma underwent high frequency ultrasound. Results Muscle tearing was detected in 34 patients, whiletendon rupture in 6, articular cavity hematocele in 19, ligament injuries in 10, muscle tissues hematoma in 17, myositis ossificans in 6 and foreign bodies in 11 patients. Subcutaneous tissue thickening, muscular edema and echo disorder were found at 116 sitesin 97 patients. Conclusion High frequency ultrasound can be used as a convenient and dynamic imaging examination method for acute extremity soft tissue injuries after trauma.
