Anatomical study of sciatic nerve and its variations – a cadaveric study in north karnataka region

Abstract

ABSRACT Aims In many conditions like trauma, inflammation, intramuscular injections and entrapment sciatic nerve is involved. Considering these it is essential to know the course and variations of sciatic nerve. Methods Dissection was done on 21 formalin embalmed cadavers. According to Cunningham’s manual dissection was done and piriformis and sciatic nerve were exposed. Results Sciatic nerve existed the pelvis through the greater sciatic foramen below piriformis as a single nerve without division in 33 specimens out of 42 gluteal regions. Most common site of division of sciatic nerve is at popliteal fossa in both sexes. Conclusion The main essence of this study is to get information on variations of the sciatic nerve anatomy. It emphasizes proper clinical implications,for the surgeons to practice efficient surgical recombination and avoid errors. Treatment aimed at maximizing the mobility of the lower limbs.
