ABSTRACT

A detailed knowledge of the internal structure of the tendon may turn out to be helpful in better diagnosis and possible successful reconstruction of the ruptured common calcaneal tendon.
The aim of the study was to relate individual tendons fibers contributing to the formation of the examined tendon (the common calcanel tendon) with its layers and parts. We examined six separated pelvic limbs of the horse previously fixed in 10% formaldehyde. The layer-by-layer method was used during dissection. We separated individual muscles and then analyzed the internal structure of the full-length common calcaneal tendon between the muscle bellies and the attachment to the tuber calcanei.
The flexor digitorum superficialis constitutes the most superficial layer of the tendon. The fascicle composed of fibers from the soleus and the lateral head of the gastrocnemius forms the deeper layer and it contributes to formation of the medial border of the common calcaneal tendon. Deeper to the latterly mentioned the fascicle of the medial head of the gastrocnemius can be identified. The tarsal tendons of the biceps femoris and the semitendinosus represent the deepest layer of the tendon.
The common calcaneal tendon it is built of the fascicles from individual muscles and that rotation around the long axis of the tendon can be observed.

Key words: tendon, horse, common calcaneal tendon, rotation, fascicles.
