Anatomical variation of sciatic nerve bifurcation in popliteal fossa- Ultrasonographic assessment in Indian population

Sciatic nerve block has been used for various surgeries and maintenance of analgesia below the knee. Our aim of this study is to assess the level of bifurcation of sciatic nerve from popliteal crease and depth of bifurcation among Indian population using ultrasound guidance. This will help us to establish a reference point in our population which will be helpful while performing landmark guided sciatic nerve block.
