OBJECTIVE To assess whether a nonparticulate steroid (dexamethasone, 10 mg) is less clinically effective than the particulate steroids (triamcinolone, 80 mg; betamethasone, 12 mg) in lumbar transforaminal epidural steroid injections (TFESIs) in subjects with radicular pain with or without radiculopathy. DESIGN Retrospective observational study with(More)
SETTING Interventional procedures directed toward sources of pain in the axial and appendicular musculoskeletal system are performed with increasing frequency. Despite the presence of evidence-based guidelines for such procedures, there are wide variations in practice. Case reports of serious complications such as spinal cord infarction or infection from(More)
BACKGROUND Transforaminal epidural steroid injections (TFESI) have demonstrated efficacy and effectiveness in treatment of radicular pain. Despite little evidence of efficacy/effectiveness, interlaminar epidural steroid injections (ILESI) are advocated by some as primary therapy for radicular pain due to purported greater safety. OBJECTIVE To assess(More)
We present a case of delayed presentation of a subdural haematoma causing cauda equina syndrome which occurred 96 hours after a spinal anaesthetic had been administered for an elective total hip replacement in an 86-year-old man. The patient had received low-molecular-weight heparin anticoagulation which had been delayed until 12 hours postoperatively. No(More)
OBJECTIVE To assess whether the immediate anesthetic response of pain relief (sensory blockade) or weakness (motor blockade) after lumbar transforaminal epidural steroid injection (TFESI) is associated with longer term effectiveness in pain relief and functional recovery. DESIGN Retrospective observational study. SETTING Single academic radiology(More)
The objective of this study is to determine the relationship of the variations of the lumbar lordosis angle (LLA) to the aortic bifurcation level and inferior vena cava (IVC) confluence level using CT angiography. A retrospective study was conducted using the data available on abdominopelvic CT angiography scans. The LLA, the level and angle of bifurcation(More)
The level of termination of the conus medullaris (CM) and thecal sac (TS) is subject to variations. We try to correlate in this study these variations with the lumbar lordosis angle (LLA) using MRI scans. A retrospective study was conducted using available MRI scans of the lumbar spine. The CM level of termination (CMLT) and the TS level of termination(More)
OBJECTIVE To examine associations between imaging characteristics of compressive lesions and patient outcomes after lumbar transforaminal epidural steroid injections (TFESIs) stratified by steroid formulation (solution versus suspension). DESIGN/SUBJECTS Retrospective observational study, academic radiology practice. A 516-patient sample was selected from(More)
