The current case report describes an uncommon insertion of the levator scapulae (LS), which broadly attaches to multiple structures, including the serratus posterior superior, ligamentum nuchae, and the 6th and 7th spinous processes of the cervical vertebrae. The most superior portion of this aponeurosis merged with the ligamentum nuchae at the C7 level. The middle and inferior portions of the head were inserted (or fused) into the tendon of the rhomboid minor as well as the fibers of the serratus posterior superior muscle. Consequently, recognizing this anatomical variation, characterized by an additional slip of the LS attaching to the 7th vertebra and other muscular structures, is crucial not only for anatomists but also for surgeons performing procedures on the posterior neck related to cervical or shoulder pain and cervical dystonia.
本病例报告描述了肩胛提肌（LS）一种不常见的附着情况，该肌肉广泛附着于多个结构，包括后锯肌上部、项韧带以及颈椎第6和第7棘突。该腱膜的最上部在C7水平与项韧带融合。肌腹的中部和下部附着（或融合）于小菱形肌腱以及后锯肌上部的纤维。因此，认识到这种以肩胛提肌额外附着于第7颈椎和其他肌肉结构为特征的解剖变异，不仅对解剖学家至关重要，对于在后颈部进行与颈部或肩部疼痛以及颈部肌张力障碍相关手术的外科医生也至关重要。
