Conclusion
The variation of sciatic nerve division at different level of the body is challenging for diagnostic and therapeutic procedure in many clinical and surgical cases.
Quick recognition of sciatic nerve variation (Fig.25) makes surgical approaches more precise and effective (Fig.
26).
Its distribution is associated with different structures and blood vessels which are important to conduct a safe operation and good outcome. The sciatic nerve,
the largest branch of lumbosacral plexus is composed of ventral and dorsal divisions of ventral rami of L4 to S3 spinal nerves [1].
The sciatic nerve is formed when the large dorsal component of the sacral plexus (common fibular nerve) and the ventral component (tibial nerve) move downward close together and hence the common peroneal and tibial components can separate from each other at various levels from their origin.
USE images tend to be good and currently only diagnostic procedure which,
based on nerve stiffness may give us information about nerve entrapment degree.
Knowing this,
it may not be so difficult to understand US elastography results and find places of nerve entrapment and bifurcation based on nerve thightning and SI values on elastography,
but more research is needed to confirm these findings.
