This elimination half-life after lumbar epidural administration is much longer than the elimination half-life of intravenous administration and is likely explained by the suspension and redistribution of the depot preparation within the epidural fat and the epidural anatomy [ 7 - 9 ].

The sciatic nerve is formed by the merging of 5 spinal nerves. (spine-health.com)
The tibial branch of the sciatic nerve is derived from the L5, S1, S2, and S3 spinal nerves. (spine-health.com)
The common peroneal branch of the sciatic nerve is derived from the L4, L5, S1, and S2 spinal nerves. (spine-health.com)
The sciatic nerve helps facilitate several movements of the foot. (spine-health.com)
If the sciatic nerve is impaired in any way, the affected portion of the nerve root or sciatic nerve determines which motor functions are affected. (spine-health.com)
An example of a sciatic nerve root-related motor dysfunction is foot drop (difficulty in lifting the front part of the foot) and steppage gait , which occurs when the L5 nerve root in the lumbosacral joint is affected. (spine-health.com)
When the main body of the sciatic nerve is affected, sciatic neuropathy occurs. (spine-health.com)
General motor impairment signs of a sciatic nerve problem include difficulty or inability to walk, bend the leg, and/or stand on tiptoe or heel. (spine-health.com)
It's a branch of the sciatic nerve that travels from the back of your thigh along the outside of your knee to the front of your lower leg. (clevelandclinic.org)
The main nerve traveling down the leg is the sciatic nerve. (mountsinai.org)
The sciatic nerve is located in the back of the leg. (mountsinai.org)
The sciatic nerve also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot. (mountsinai.org)
Several different tests can be performed to find the cause of sciatic nerve dysfunction. (mountsinai.org)
Sciatica occurs when there is pressure on or damage to the sciatic nerve. (mountsinai.org)

Nerves carry messages back and forth from your low back and legs. (uofmhealth.org)
Near the back of the knee, the nerve divides into the tibial and common peroneal (fibular) branches. (spine-health.com)
Nerves that start in this area of your back extend down to your legs and feet. (clevelandclinic.org)
The low back, or lumbar area, serves several important functions for the human body . (medicinenet.com)
Dying back patterns of nerve damage from acrylamide were studied in Sprague-Dawley-rats. (cdc.gov)

A nerve block is a local anesthetic injected near a nerve or the spinal cord or nerve root. (uofmhealth.org)
Your doctor often can also tell which nerve root is involved. (uofmhealth.org)
Essentially, this occurs when one side of the spinal disc bulges, potentially irritating the nerve root. (concordia.ca)
Anterior Cervical Discectomy and Fusion (ACDF): An intervertebral disc in the cervical spine bulges or herniates, exerting pressure on an adjacent nerve root. (pr.com)

The pharmacokinetics of cervical epidural-administered triamcinolone is consistent with our previous study of lumbar ESI, demonstrating that the elimination half-life is longer than that which has been reported following intravenous triamcinolone. (hindawi.com)
Recently, our group reported on the pharmacokinetics of lumbar epidural-administered triamcinolone [ 7 ]. (hindawi.com)
The terminal elimination half-life of lumbar epidural-administered triamcinolone in a noncompartmental analysis was 523 hours, and the peak triamcinolone concentration of 4.1 ng/mL was detected within 24 hours after administration. (hindawi.com)
Knowledge of pharmacokinetic parameters of this corticosteroid following epidural administration into other areas of the spine beyond the lumbar region is necessary to help us better understand the duration of clinical effect and to compare the results to the results of lumbar epidural injection.
