The adductor longus muscle, with its proximal origin at the pubic bone and distal at the linea aspera, is reported to be one of the most frequently injured groin muscles in contact sports, namely football or ice hockey. Notwithstanding, there is a scarcity of published works regarding the accessory heads of the adductor longus muscle in the existing literature, let alone the clinical significance of the said variant. The following study is a case report describing bilateral accessory heads of the adductor longus muscle in a 97-year-old female cadaver. A routine cadaveric dissection revealed two accessory heads on the right thigh and one on the left thigh of a donor with no known structural or pathological abnormalities of the proximal lower extremity. The anterior division of the obturator nerve provided nerve supply to the variants on both sides. The deep femoral, superficial external pudendal, femoral vessels were responsible for the vascular supply to the accessory heads of the adductor longus. Undoubtedly, extensive knowledge regarding the variant anatomy of the hip adductor muscles is of immense importance to physiotherapists and orthopaedists treating patients for their injury or complete tears. Nonetheless, there is little information regarding the accessory heads of the adductor longus in the existing literature (originating mostly from cadaveric studies) that requires further evaluation in vivo to assess whether this variant might have an impact on a patient's everyday life.
内收长肌，近端起于耻骨，远端止于粗线，据报道是足球或曲棍球等接触性运动中最常受伤的腹股沟肌肉之一。然而，关于内收长肌的副头在现有文献中发表的作品很少，更不用说这种变异的临床意义了。本研究是一例报告，描述了一名 97 岁女性尸体的双侧内收长肌副头。在一名捐赠者的右大腿和左大腿上进行了常规尸体解剖，发现有两个副头，没有发现近端下肢的结构或病理异常。闭孔神经前支为两侧变异提供神经支配。股深动脉、浅外阴部血管为内收长肌副头提供血液供应。毫无疑问，广泛了解髋关节内收肌的变异解剖对治疗患者损伤或完全撕裂的物理治疗师和矫形外科医生非常重要。然而，关于内收长肌副头的信息在现有文献中很少（主要来源于尸体研究），需要进一步在体内进行评估，以确定这种变异是否会影响患者的日常生活。
