Interindividual variability presents a rich field of study in medical sciences. During a cadaveric dissection at Louisiana State University Health Sciences Center, a rare anatomical variation was discovered in the pedal anatomy of a female cadaver. Medical students, while dissecting the sole of the foot, identified a variant tendinous structure. This aberrant tendinous slip from the flexor hallucis longus (FHL) extended to the lateral four tendons of flexor digitorum longus (FDL) along the plantar aspect of the foot. The discovery suggested that the FHL shares a functional relationship with the FDL. Application of tension to the FHL was found to result in simultaneous flexion motion in the lesser toes, from the second to the fifth digit. The presence of this anatomical variant holds considerable importance for surgical interventions, especially as a potential graft source in tendon reconstructions, warranting its documentation in this report.
个体间差异是医学科学中一个丰富的研究领域。在路易斯安那州立大学健康科学中心进行尸体解剖时，在一具女性尸体的足部解剖结构中发现了一种罕见的解剖变异。医学生在解剖足底时，发现了一个变异的腱性结构。这条来自拇长屈肌（FHL）的异常腱束沿着足底延伸至趾长屈肌（FDL）的外侧四条肌腱。这一发现表明FHL与FDL存在功能关系。研究发现，对FHL施加张力会导致第二至第五趾同时出现屈曲运动。这种解剖变异的存在对手术干预具有重要意义，尤其是作为肌腱重建中潜在的移植物来源，因此有必要在本报告中进行记录。
