摘要
目的探讨正常成人拇长屈肌毗邻解剖结构的高频超声声像图特征及检查方法,为拇长屈肌损伤的诊断及治疗提供影像学信息。资料与方法 55例正常志愿者上肢呈解剖位,应用高频超声检查110侧拇长屈肌毗邻解剖结构,观察拇长屈肌毗邻关系及超声声像图特征。结果以拇长屈肌作为解剖标志,高频超声清晰地显示了前臂腹侧拇长屈肌起始段、上段、旋前方肌段、大鱼际第一掌骨中点处拇长屈肌腱短轴毗邻的声像图特征,详细描述了鱼际间隙和拇收肌后间隙的超声解剖关系。55例受检者中,19例存在起始部拇长屈肌副头先天变异,其中2例起始于喙突,17例起始于肱骨内上髁。结论以拇长屈肌作为解剖标志,高频超声可以清晰地显示拇长屈肌及其周围肌肉、骨骼、神经、血管的毗邻关系与声像图特征,可以作为拇长屈肌及其毗邻结构的首选无创性检查方法,值得临床推广应用。
Purpose To explore the high-frequency ultrasonographic characteristics and examination method of structures adjacent to flexor pollicis longus in normal adults, and to provide imaging information in diagnosing and treating flexor pollicis longus injury. Materials and Methods The adjacent structures of flexor pollicis longus in 110 forearms of 55 normal volunteers were scanned in anatomic position using high-frequency ultrasound. The relationship and ultrasonographic features were observed. Results Using the flexor pollicis longus as anatomic land mark, high-frequency ultrasound clearly demonstrated the adjacent structures at the origin, the superior segment, the pronator puadratus segment, and the short axis at center of the first metacarpal. The anatomical relationships of the thenar space and posterior adductor pollicis space were described. In 55 volunteers, 19 were found to have accessory head of flexor poUicis longus, including two originating from the coronoid process and 17 originating from the medial epicondyle of the humerus. Conclusion Using the flexor pollicis longus as anatomic land mark, highfrequency ultrasound can depict the muscle and surrounding muscle, bones, nerves and vasculature. It is the first line imaging modalily in evaluating the forearm.
