Cadavaric Study of Variations in Divisions of Sciatic Nerve
Introduction: Sciatica is the pain caused by a compression or irritation of the Sciatic Nerve (SN) and the symptoms include nerve pain, numbness, tingling, and weakness. The clinical values are unilateral or bilateral higher break of SN that result in compression of nerve that leads to piriformi...

| description | Introduction: Sciatica is the pain caused by a compression
or irritation of the Sciatic Nerve (SN) and the symptoms
include nerve pain, numbness, tingling, and weakness. The
clinical values are unilateral or bilateral higher break of SN
that result in compression of nerve that leads to piriformis
syndrome. This pressure on nerve results in paralysis of
the supplied muscles and sensory disturbances.
Aim: To observe the variations in the site of divisions of SN
and relation to the piriformis muscle.
Materials and Methods: This cross-sectional study was
carried out after taking ethical approval from Institutional
Ethical Committee (IEC) of present institute during year
2015 with duration of one and half year at Anatomy
Department of GMERS Medical College, Gandhinagar
in about 30 properly embalmed cadavers (total 60 lower
limb/extremities) during routine dissection.
Results: Total of 60 gluteal regions were examined for the
variation in the course and division of the SN. Among them
in 51 lower limbs (85%) the SN had a normal course after
its exit below the piriformis and divided into tibial nerve and
common peroneal nerve at the superior angle of popliteal
fossa, while in nine lower limbs (15%) there were higher
division site of SN observed.
Conclusion: During posterior hip operations, this high
division develops in sciatica, nerve injury during deep
intramuscular injections, piriformis syndrome, failed sciatic
nerve block in anesthesia and injury. Lower limb surgeries
and in the interpretation of sciatic neuropathy can be
complicated by variation in division of SN. |
