Aim: To study the variant soleus muscle. Materials and methods: 50 lower limbs of 25 donated embalmed cadavers (15 males & 10 females) of age group ranging from 70 to 80 years were studied in the department of Anatomy at K. J. Somaiya Medical College, Sion, Mumbai, INDIA. The left lower limb of one male cadaver showed the three separate heads of soleus muscle. All the lower limbs were thoroughly and meticulously dissected to note the variation of the soleus muscle. The arterial pattern in the leg was also observed. The photographs of the variation of the soleus muscle were taken for proper documentation. Observations: Out of 100 specimens the variations in the soleus muscle was found in one specimen. The left lower limb of a female cadaver showed three separate heads of soleus muscle. The tibial head from soleal line present on the posterior surface of the tibia, the fibular head from the back of the head of the fibula and the intermediate head from the tendinous arch placed between the tibial and the fibular origins of the muscle. The three heads of soleus muscle along with the medial and the lateral heads of gastrocnemius formed the tendo calcaneus which got inserted into the middle part of the posterior surface of the calcaneus bone. There was no associated arterial variations seen in the specimen. The variation was unilateral and the right lower limb of the same cadaver was normal. Conclusion: The existence of such variation of the soleus muscle should be kept in mind by the surgeons, the orthopaedicians, the radiologists and also by the physiotherapists. The three heads of soleus may prove significant and lead to confusion during surgical procedures. A lack of awareness such variations might complicate surgical repair.
