No detailed reports exist describing the methodology of ultrasound image acquisition of the deep external rotator muscles of the hip. Because gluteal pain and sciatica are common, ultrasound may be a useful dynamic imaging adjunct in the evaluation of these patients.
To describe dynamic ultrasonography of the deep external rotator muscles of the hip for diagnostic purposes.
Descriptive.
University radiology department.
Participants (n = 25; 14 male) without gluteal pain or sciatica were enrolled (mean age 27.6 ± 4.7 years; mean body mass index 26.0 ± 4.1 kg/m(2)).
Ultrasonographic cine clips oriented to the long axis of each deep external rotator muscle were captured. In addition, cine clips of the piriformis tendon and obturator internus tendon were obtained. Cine clips were analyzed approximately 1 week after completion of image acquisition independently by 2 blinded raters.
A 5-point Likert scale to evaluate the diagnostic utility of the ultrasound image.
The modal Likert scores for rater 1 were as follows: piriformis muscle = 4; piriformis tendon = 4; superior gemellus muscle = 3; obturator internus muscle = 4; obturator internus tendon = 4; inferior gemellus muscle = 4; quadratus femoris muscle = 4. The modal scores for rater 2 were: piriformis muscle = 4; piriformis tendon = 3; superior gemellus muscle = 4; obturator internus muscle = 3; obturator internus tendon = 4; inferior gemellus muscle = 3; quadratus femoris muscle = 4.
Dynamic ultrasonography may be useful to image the hip deep external rotator musculature for diagnostic purposes and therefore aid in the evaluation of gluteal pain and sciatica. Future work should investigate the reliability and validity of ultrasonography in the evaluation of pathology of these muscles.
目前尚无详细报告描述髋部深层外旋肌超声图像采集的方法。由于臀肌疼痛和坐骨神经痛较为常见，超声可能是评估这些患者时一种有用的动态成像辅助手段。
描述用于诊断目的的髋部深层外旋肌动态超声检查。
描述性研究。
大学放射科。
招募了25名（14名男性）无臀肌疼痛或坐骨神经痛的参与者（平均年龄27.6±4.7岁；平均体重指数26.0±4.1kg/m²）。
采集沿每条髋部深层外旋肌长轴方向的超声电影剪辑。此外，还获取了梨状肌腱和闭孔内肌腱的电影剪辑。图像采集完成约1周后，由2名不知情的评估者独立分析电影剪辑。
采用5分制李克特量表评估超声图像的诊断效用。
评估者1的李克特量表评分模式如下：梨状肌=4分；梨状肌腱=4分；上孖肌=3分；闭孔内肌=4分；闭孔内肌腱=4分；下孖肌=4分；股方肌=4分。评估者2的评分模式为：梨状肌=4分；梨状肌腱=3分；上孖肌=4分；闭孔内肌=3分；闭孔内肌腱=4分；下孖肌=3分；股方肌=4分。
动态超声检查可能有助于对髋部深层外旋肌进行成像以用于诊断目的，从而有助于评估臀肌疼痛和坐骨神经痛。未来的研究应探讨超声检查在评估这些肌肉病变方面的可靠性和有效性。
