Volume of contrast and selectivity for lumbar transforaminal epidural steroid injection.
BACKGROUND It has been shown that L4/L5 selective nerve root blocks become nonselective after injecting 1 mL and 0.5 mL of contrast. Volumes of less than 0.5 mL have not been used to determine a volume of definite specificity. OBJECTIVE This study attempts to identify the minimum volume of contrast at which selectivity is maintained without spread to the superior or inferior end plate. STUD...
متن کاملContrast flow selectivity during transforaminal lumbosacral epidural steroid injections.
BACKGROUND Lumbosacral transforaminal epidural steroid injections (LS-TFESIs) are an accepted procedure used in the comprehensive, conservative care for lumbar disc pathology and/or spinal stenosis induced low back pain with a radicular component. Historically, the terminology used to describe the transforaminal technique of instilling medications into the epidural space and/or exiting structur...
متن کاملAnalysis of Influencing Factors to Depth of Epidural Space for Lumbar Transforaminal Epidural Block in Korean
BACKGROUND Transforaminal epidural steroid injection is one of the effective treatments in managing radicular pain. There have been some prospective studies on the depth to the epidural space with the transforaminal approach. However, there have been no studies about the depth in Asians, especially Koreans. This study was carried out in order to evaluate the depth to the epidural space and the ...
متن کاملContrast Spreading Patterns in Retrodiscal Transforaminal Epidural Steroid Injection
OBJECTIVE To observe the contrast spreading patterns in the retrodiscal (RD) approach for transforaminal epidural steroid injections and their effect on pain reduction. METHOD Patients with L5 radiculopathy who were scheduled to receive lumbar TF-EPB were consecutively included. We randomly divided them into the L4-5 RD and L5-S1 RD groups and administered 1 cc of contrast dye into epidural s...
متن کاملClonidine as an Adjuvant in Fluoroscopic-guided Transforaminal Epidural Steroid Injection in a Patient of Chronic Lumbosacral Radiculopathy
Transforaminal epidural steroid injection (TFESI) is a minimally invasive modality used to treat patients with lumbosacral radiculopathy secondary to prolapsed intervertebral disc or spinal canal stenosis. In this case report, we describe the management of a patient with chronic lumbosacral radiculopathy secondary to intervertebral disc herniation which was seen as a right paracentral disc prot...
