VARIATIONS IN DIVISION OF SCIATIC NERVE: A CADAVERIC STUDY
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2016, Vol 3, Issue 17
Abstract
INTRODUCTION Sciatic nerve is the largest and thickest nerve in the body. It arises from the lumbar plexus within the pelvis. The nerve emerges from the pelvis to enter into its component nerves –tibial and common peroneal nerve. The division normally occurs at the lower apex of the superior angle of popliteal fossa of the thigh. However the division shows variations which may be inside the pelvis or outside the pelvis When outside, the division may occur anywhere from exit to apex of the popliteal fossa where nerve normally divides. These abnormal divisions of the may be aetiological factors for the pathologies related to the nerve. MATERIALS AND METHODS The study was done on twenty cadavers used in routine dissection for the under graduate students from Kanyakumari Government Medical College, Asaripalam, Nagarcoil, Kanyakumari District, Tamilnadu. The cadavers were fixed in 10% in formalin, glycerine, isopropylol, and sodium chloride solution. Of these, two cadavers showed higher division of sciatic nerve. The division has occurred at the lower border of piriform is and divided nerve has emerged from the lower border of the pyriformis. Variations were seen on both the sides in these two bodies. CONCLUSION A thorough knowledge of division sciatic nerve helps in differential diagnosis of sciatica of various origins & its management by the different treatment methods.
