Sciatic Nerve Morphometry in the Gluteal Region in a Nigerian Population: An Anatomical Study

Abstract

The sciatic nerve is frequently used in anesthesia, neurology, orthopedics, and rehabilitative medicine procedures. Due to its girth, the sciatic nerve is one of the human body's most often injured nerves. Unawareness of the structural differences of this nerve may be a contributing factor in damage. The purpose of the study is to evaluate the usual morphomety of the sciatic nerve and piriformis muscle. Lower limbs (N = 10) from Nigerian cadavers were chosen for this study's morphological examination and dissection. There were 8 males and 2 females in total. Using a computerized sliding calliper, the piriformis and sciatic nerve characteristics were examined and statistically analyzed.The right medial width (32.20±1.45mm) of the piriformis muscle was larger compared to the left (31.91±1.65mm). However, it was not so for lateral width of the piriformis muscle as the left was larger (17.35±0.25mm) compared to the right (17.09±0.17mm).The right length of superior piriformis border was larger (54.57±1.58mm) compared to the left (52.19±2.87mm). In comparison to the female specimens, the mean length of the sciatic nerve was substantially longer in the male specimens (p 0.05).
