Injuries to the adductor longus commonly occur in the proximal part of the muscle tendon unit, close to the insertion site on the pubic bone. Ultrasonography, magnetic resonance imaging (MRI) and surgery have been helpful in localising the lesions, but the exact anatomy of the musculotendinous junction (MTJ) and insertion of the muscle remain unclear. We studied the anatomical features of the MTJ and measured the dimensions of the tendinous insertion into the pubic bone on 37 cadavers: 18 men and 19 women. The medial boundaries were the longest part of the tendon bilaterally in women, while the lateral aspect of the left muscle was greater in men. Tendinous fibres were predominantly found on the anterior surface, while the posterior surface consisted mainly of muscle tissue. The MTJ was clearly demarcated. There were several types of anomalies present which partially explains the difficulty in localising the site of injury and highlights the importance of individualized treatment.
长收肌损伤通常发生在肌腱单元的近端，靠近耻骨上的附着点。超声、磁共振成像（MRI）和手术有助于定位病变，但肌腱结合部（MTJ）和肌肉附着的确切解剖结构仍不清楚。我们研究了37具尸体（18名男性和19名女性）的MTJ解剖特征，并测量了耻骨上肌腱附着的尺寸。双侧肌腱的内侧边界在女性中是最长的部分，而左侧肌肉的外侧在男性中更大。肌腱纤维主要位于前表面，而后表面主要由肌肉组织组成。MTJ界限清晰。存在几种类型的异常，这部分解释了定位损伤部位的困难，并突出了个体化治疗的重要性。
