Anatomical Variation of the Sciatic Nerve in Relation to the Piriformis Muscle: An MRI Study

SUMMARY Background. The sciatic nerve is the largest and thickest branch of the lumbosacral plexus. It separates into numerous branches and exhibits multiple anatomical variations that may result in nerve compression, a factor that is attributed to its location in the pelvis. This study aims to detect sciatic nerve branch variation and its association with the piriformis muscle and … Continued
