Morphological Aspects Of Triceps Surae – A Cadaveric Study

Abstract

Introduction : Gastrocnemius and soleus belong to the superficial group of muscles of the posterior compartment of the leg. Equinus is the pathological condition affecting  the lower limbs which usually remains unrecognized and untreated. Technologically and surgically advanced technique being used for the treatment of equinus is Endoscopic gastrocnemius recession (EGR). However with any endoscopic technique proper placement of the surgical instrument is imperative to success. One of the areas of utmost confusion with this technique is at what level the gastrocnemius has to be transected. Unfortunately there is no particular measurement accepted universally that would work for each  patient to carry out the transection. 

Aim : To study the morphology and variations of Gastrocnemius and  its attachment with the Soleus which could  be valuable to  the surgeons for appropriate placement of instruments  for successful  transection.The study was carried out in 60 embalmed specimens(60 lower limbs). The dissection method followed was according to the Cunningham's Manual Of  Practical Anatomy.

Conclusion : A thorough understanding of the variations in the gastrocnemius aponeurosis will help the practicing surgeons in the appropriate placement of the endoscopic instruments and hence leading to an efficient procedure without any iatrogenic complications .
