目的为临床诊治背阔肌腱下滑囊炎提供应用解剖学基础。方法 20侧成人肩关节标本(右11侧、左9侧),对背阔肌腱下滑囊及与其邻近易误诊的解剖结构进行观测。结果背阔肌腱下滑囊位于肱骨结节嵴间沟底、肱骨小结节嵴、大圆肌附着部与背阔肌腱止点之间。肱骨结节间沟可分为肱骨大、小结节间沟和大、小结节嵴间沟,确定该滑囊的上下位置,即从肱骨小结节最高点至背阔肌腱下滑囊上端距离为(27.43±4.71)mm,可以确定该滑囊的上下位置,背阔肌腱下滑囊的内外位置关系,从肱二头肌长头腱内侧缘距背阔肌腱下滑囊中点为(8.12±1.23)mm,可以确定该滑囊的内外位置关系。背阔肌腱下滑囊的相关数据,在肱骨结节嵴间沟上、下高度为(36.5±4.79)mm,中点宽度为(8.62±1.83)mm。背阔肌腱下滑囊周围易发生炎症的有肱二头肌长头腱滑液鞘、大圆肌腱下滑囊、喙突下滑囊、胸大肌骨管等。结论本研究为背阔肌腱下滑囊的诊疗提供了形态学依据。
Objective To provide an anatomical basis for the clinical diagnosis and treatment of latosal bursitis. Methods 20 adult shoulder specimens (right 11, left 9) were used to observe the anatomical structures of the lateral bursa of tendon and its adjacent misdiagnosis. Results The dorsal forelimb tendon was located between the humeral tubercle crest base, the humerus small nodule ridges, the dorsalis muscle attachment and the latissimus dorsi only. Humeral nodules between the groove can be divided into large and small humeral nodules and large and small nodules between the crest of the ridge to determine the up and down the position of the bursa, that is, from the highest point of the humerus nodules to the distance between the upper end of the dorsal flexor tendon (27.43 ± 4.71) mm, the up-and-down position of the bursa of the bursa and the position of the inferior bursa of the dorsal flexor tendon can be determined from the medial border of the long tendon of the biceps to ) mm, to determine the internal and external position of the relationship between the bursa. The data of the lower latissimus dorsius ascending bursa was (36.5 ± 4.79) mm in the sulcus of the humerus nodules, and the median width was (8.62 ± 1.83) mm. Lateral Tendon tendon around the synovial bursitis prone to inflammation of the biceps long tendon synovial sheath, the greater circular tendon bursa, coracoid bursa, pectoralis major tube. Conclusion This study provides a morphological basis for the diagnosis and treatment of the LADD.
