Accessory soleus muscle

The accessory soleus muscle is an anatomical variant characterised by an additional distinct muscle encountered along a normal soleus muscle. It is uncommon with a prevalence of ~3% (range 0.7-5.5%).

The accessory soleus muscle arises from the deep surface of the soleus or from the fibula and descends anteriorly to the calcaneal tendon. Its insertion may occur into the calcaneal tendon, the upper surface of the calcaneus, or in the medial aspect of the calcaneus.
