The body is home to a number of unique and intriguing anatomical structures, plenty of which concern the muscles and their tendons. Of these, the plantaris muscle is reported to present a particularly high range of morphological variations. The muscle, passing distally throughout the length of the lower leg, consists of a small muscle belly and a long, thin tendon. It originates, traditionally, on the popliteal surface of the femur and the knee joint capsule, and then inserts to the calcaneal tuberosity. It has been suggested that mid-portion Achilles tendinopathy may be caused by certain plantaris tendon morphologies. This case report describes a new anomalous plantaris tendon insertion, closely related to the Achilles tendon. It comprise four distinct insertions and one direct merge with the calcaneal tendon. The current classification should be extended to accommodate such 'rare cases' to facilitate more successful Achilles tendinopathy treatment.
人体拥有许多独特且引人入胜的解剖结构，其中很多与肌肉及其肌腱有关。在这些结构中，跖肌据报道呈现出特别高的形态变异范围。该肌肉沿小腿全长向远端走行，由一个小肌腹和一条长而细的肌腱组成。传统上，它起于股骨的腘面和膝关节囊，然后止于跟骨结节。有人认为，中部跟腱病可能由某些跖肌腱形态引起。本病例报告描述了一种与跟腱密切相关的新型异常跖肌腱附着情况。它包括四个不同的附着点和一个与跟腱的直接融合。当前的分类应加以扩展以纳入此类“罕见病例”，以便更成功地治疗跟腱病。
