Abstract

Introduction: Gastrocnemius has a medial and lateral belly. It joins with soleus to get inserted as the Achilles tendon. Accessory heads of gastrocnemius can give rise to popliteal artery entrapment syndromes.
Materials and Method: 60 formalin embalmed lower limbs mere meticulously dissected to see for any variation in number of heads and nerve supply of Gastrocnemius.
Observations: 15% limbs showed accessory heads of gastrocnemius. 8.34% showed 4 heads and 6.66% showed 3 heads. Length of Achilles tendon in limbs with variation ranged from 6.1 cm to 12.8 cm.
Conclusion: Knowledge of accessory heads of gastrocnemius will help the radiologist during imaging studies in cases of polpliteal entrapment syndromes and neurovascular compression.
