A Cadaveric Study of Sciatic Nerve and It's Level of Bifurcation ABSTRACT Sciatic nerve, the thickest nerve in the body, formed in the pelvis, emerges through greater sciatic foramen to enter the gluteal region, then the nerve passes on the back of thigh to reach the superior angle of popliteal fossa and bifurcates into tibial and common peroneal nerves. But the level of bifurcation varies. The...

Direct percutaneous stimulation of the proximal sciatic nerve with a high voltage electrical stimulator was given to a patient with acute sciatic compression neuropathy. Results clearly showed a focal conduction block at the sciatic notch, which could not be precisely localised and quantified by conventional electrodiagnostic methods.

Sciatic nerve injury and dysfunction is not an uncommon cause of lower extremity symptoms in a musculoskeletal practice. The sciatic nerve derives its nerve fibers from the L4, L5, S1, S2, and S3 nerve roots. The sciatic nerve arises from the lumbosacral plexus and is composed of two distinct trunks: the lateral (peroneal division) and the medial (tibial division). The peroneal and the tibial d...

Following traumatic peripheral nerve injury reinnervation of denervated targets may be achieved by regeneration of injured axons and by collateral sprouting of neighbor undamaged axons. Experimental models commonly use sciatic nerve injuries to assess nerve regeneration and neuropathic pain, but behavioral tests for evaluating sensory recovery often disregard the pattern of hindpaw innervation....

Sciatic nerve palsy is a recognised complication of primary total hip replacement. In our unit this complication was rare with an incidence of < 0.2% in the past ten years. We describe six cases of sciatic nerve palsy occurring in 355 consecutive primary total hip replacements (incidence 1.69%). Each of these palsies was caused by post-operative haematoma in the region of the sciatic nerve. Cas...

Sciatica is characterized by pain and discomfort occurring frequently with impingement at the level of spinal nerve along the regions innervated by the sciatic nerve. Compression and irritation of the nerve often occurs with a spinal cause such as lumbar disc hernia or spinal stenosis. Compression of the nerve by an arteriovenous malformation is very rare among the causes leading to non-discoge...

The incidence of iatrogenic peripheral nerve injury during hip arthroplasty procedures has been reported to be between 0.6 and 1.3 percent. The relative risk of nerve palsy is higher in certain groups of patients such as women, patients with developmental dysplasia of the hip, and those who have undergone revision arthroplasty. In this study, the dynamic relationship between the acetabulum and ...

GM1-gangliosidosis is a glycosphingolipid lysosomal storage disease involving accumulation of GM1 and its asialo form (GA1) primarily in the brain. Thin-layer chromatography and X-ray diffraction were used to analyze the lipid content/composition and the myelin structure of the optic and sciatic nerves from 7- and 10-month old β-galactosidase (β-gal) +/? and β-gal -/- mice, a model of GM1gangli...
