BACKGROUND In human, the bulk of the posterior compartment of the leg is formed by the gastrocnemius and the soleus muscle. The superficially-placed gastrocnemius is a bipennate muscle, but according to available literature, it exhibits numerous anatomical variations. The aim of the present study is to find out the anatomical variations of the gastrocnemius muscle in this part of Assam. included 30 lower limbs from 15 embalmed cadavers of known sexes. These cadavers were provided to the first

After carrying out the dissection as per Cunningham's Manual of Practical Anatomy, the gastrocnemius muscle was examined for its two heads of origin. Any accessory heads found were noted and recorded. RESULTS Out of the 30 lower limb specimens, 28 (93.33%) limbs presented with the normal two-headed gastrocnemius muscle, while 2 (6.66%) limbs (1 right and 1 left), presented with four-headed gastrocnemius muscle. Both these limbs belonged to male cadavers. CONCLUSION The precise knowledge of occurrence of multi-headed gastrocnemius muscle should be kept in mind, while performing myocutaneous flaps around the knee joint and also during limb salvage procedures or limb sparing surgery.
