Article Abstract
This study aimed to validate previously published computed tomography (CT) derived mathematical equations with the true skin to lumbosacral epidural distance (SLED) in dog cadavers. Phase 1: The lumbar region of 11 dog cadavers were scanned in sternal recumbency to determine the effect of cranial, neutral, and caudal pelvic limb positioning on the CT derived lumbosacral epidural distance (CLED). Phase 2: The epidural space was determined using contrast epidurography, and the SLED was analysed against the mathematical equations using a body condition score (BCS) and either the cadaveric occipital-coccygeal length (OCL) (Equation (1): = 7.3 + 0.05*OCL + 16.45*BCS) or the ilium wing distance (IWD) (Equation (2): = 3.5 + 0.56*IWD + 16.6*BCS). There were no differences detected between the pelvic limb positions and the CLED. Both equations demonstrated strong correlations (Equation (1): = 0.7196; Equation (2): = 0.7590) with the SLED. The level of agreement was greater for Equation (1) than with Equation (2) (concordance coefficient 0.6061 and 0.3752, respectively). Equation (1) also demonstrated a closer fit to the concordance line compared with Equation (2) (bias correction factor 0.8422 and 0.4960, respectively). Further studies in live anaesthetised dogs will help to determine the usefulness of the pre-procedural knowledge when performing lumbosacral epidurals.
Objectives: This study aimed to compare the treatment outcomes between dorsal root ganglion (DRG) pulsed radiofrequency (PRF) and DRG PRF plus transforaminal epidural steroid injection (TFESI) in patients with chronic lumbosacral radicular pain.
Patients And Methods: Eighty-one patients (39 males, 42 females; mean age: 57.5±11.
Chronic low back pain is a prevalent and debilitating condition that often resists traditional management strategies such as physical therapy, pharmacotherapy, and interventional procedures. The erector spinae plane (ESP) block, a relatively new regional anesthesia technique, has shown promise in managing various types of pain, including chronic conditions. This case report details the use of the ESP block in a male patient in his late 60's with chronic low back pain unresponsive to conventional treatments, including acetaminophen, muscle relaxants, gabapentin, epidural steroid injections, diagnostic medial branch blocks, and sacroiliac joint injections.
Background: Arteriovenous shunts below conus medullaris (AVS-BC) are understudied, particularly those associated with spinal dysraphism. This study aimed to refine the classification and management of AVS-BC.
Methods: A retrospective analysis of patients with AVS-BC from two centers over two decades was performed, focusing on clinical presentations, angioarchitecture, and treatment outcomes.
Background And Aims: Low back pain is a common problem and a major burden to society. Transforaminal epidural steroid injection is one of the most effective treatment modalities for back pain. We aim to objectively quantify pain relief of lumbosacral radicular pain post transforaminal steroid injection by correlating perfusion index (PI), reflecting real-time peripheral blood flow change at the site of monitoring, controlled by sympathetic system with Numerical rate score (NRS) and SLRT improvement.
: Spinal cord epidural stimulation (SCES) has the potential to restore motor functions following spinal cord injury (SCI). Spinal cord mapping is a cornerstone step towards successfully configuring SCES to improve motor function, aiming to restore standing and stepping abilities in individuals with SCI. While some centers have advocated for the use of intraoperative mapping to anatomically target the spinal cord locomotor centers, this is a resource-intensive endeavor and may not be a feasible approach in all centers.
