4 Clinical Trials for Various Conditions
The purpose of this study is to describe the contrast flow patterns in the epidural space using the inferior-anterior approach with continuous fluoroscopic guidance, and determine how well this approach correlates with appropriate contrast flow patterns and with analgesia at follow up. This knowledge may prove useful in guiding physician practice patterns in the non-surgical management of low back pain. Hypothesis: The investigators hypothesize that there will be suitable (ventral/anterior) epidural contrast spread based on inferior-anterior needle-tip position, particularly with appropriate needle tip position.
Assess clinical and radiographic outcomes in patients who undergo 1-3 level anterior cervical discectomy fusion (ACDF) or lumbar interbody fusion (TLIF, PLIF, ALIF, or LLIF) using ViBone.
Neural injury is a well-known complication following extreme lateral lumbar interbody fusion (XLIF). It has been found that up to 9.4% of patients will have either temporary or persistent neurologic deficit. This occurs with traversal of the psoas muscle or direct injury to lumbosacral plexus or sympathetic ganglion. While often temporary, it can cause hip flexor weakness, thigh numbness, or pain. Several studies have demonstrated reduced patient reported pain scores following steroid administration, particularly in the early postoperative period. However, few studies have investigated the efficacy of intraoperative local injection of corticosteroid in reducing the incidence and duration of postoperative pain or neurologic injury for XLIF patients.
This was a randomized, blinded study of transforaminal epidural injection of clonidine versus a similar injection of corticosteroid for acute lumbosacral radiculopathy. The hypothesis was that clonidine will be as effective as steroid for this condition.
