高频超声及声触诊组织量化技术对男性肩袖损伤患者冈上肌腱的评价

目的:应用高频超声及声触诊组织量化技术(VTIQ)评价男性肩袖损伤患者冈上肌腱的变化。方法:收集50例确诊的肩袖损伤男性患者,分为A组(35~59岁)28例和B组(≥60岁)22例。患者均行常规检查及VTIQ检查,测量冈上肌腱的厚度及其近端、远端的剪切波速度(SWV)。结果:常规检查示B组双侧冈上肌腱厚度均大于A组(均P<0.05)。VTIQ技术得出B组双侧冈上肌腱远端及近端的SWV值均小于A组(均P<0.05),且2组双侧冈上肌腱远端的SWV值均大于近端(均P<0.05)。结论:高频超声常规检查及VTIQ技术能有效评估男性肩袖损伤患者冈上肌腱的二维形态学改变及SWV值变化,冈上肌腱随年龄增大逐步变厚,而SWV下降表明肌腱发生软化,可为临床治疗及康复训练提供参考价值。

Evaluation of supraspinatus tendon in male patients with rotator cuff injury by high frequency ultrasound and virtual touch tissue imaging quantification

Objective:To evaluate the changes of supraspinatus tendon in male patients with rotator cuff injury by ultrasound conventional examination and virtual touch tissue imaging quantification(VTIQ).Methods:Among 50 men with rotator cuff injury,28 patients(age of 35~59 years old)were assigned to Group A and 22 patients(age above 60 years old)were assigned to Group B.All patients were examined by shoulder ultrasound conventional examination and VTIQ.The thickness of supraspinatus tendon,the SWV of proximal and distal supraspinatus tendon were measured.Results:The thickness of the supraspinatus tendon by conventional examination in Group B were significantly higher than those in Group A(both P<0.05).The SWV values of the proximal and distal supraspinatus tendon by VTIQ in Group B were lower than those in Group A(all P<0.05),and the SWV values of the distal part of the supraspinatus tendon in both groups were higher than those of the proximal part(all P<0.05).Conclusions:High frequency ultrasound and VTIQ can effectively evaluate the two-dimensional change and SWV value of supraspinatus tendon in male patients with rotator cuff injury.The increase of age makes the thickness of supraspinatus tendon gradually thicker,while the decrease of SWV value means that the tendon softens,which provides reference value for clinical treatment and rehabilitation training.
