Resumen
We report on a unique instance of anatomical variation in the gastrocnemius muscle. A 91-year-old Caucasian male cadaver was found to have a missing medial head of his left gastrocnemius. A layer of fibrous, fatty infiltration occupied the ana-tomical location of the missing musculature. Dis-section revealed no evidence of atrophy as a result of damage to nervous tissue, blood supply or mus-cle tissue death. There was no evidence of sarco-penia. No hypertrophy of the left-side-lateral head was documented when compared to the contrala-teral lower leg. There were no reports of a known defect in the musculature in the patient’s medical history. Upon superficial inspection, the extensive amount of body fat on the cadaver hid any signs of an external deformity on the leg prior to dissection. We suspect that the missing medial head was compensated for via reliance on more motor unit recruitment from the underlying soleus, as well as potential behavioural adjustments of the patient.
