A patient with previous L3-4 posterior lumbar interbody fusion, pedicle screws instrumentation and L3-4 decompression, was scheduled for left total hip arthroplasty. Two years ago, due to poor landmarks palpation, the patient experienced a failed lumbar puncture after multiple attempts before herniorrhaphy. His plain radiography showed bilateral partial laminectomy at L3-4 level, and between L3 and L4, two posterior pedicle screws connected by metal rods on both sides. This time, we used ultrasound to locate L4-5 interlaminar space in paramedian sagittal oblique view and identified the spine midline by transverse interlaminar view before puncture...

BACKGROUND: The real-time ultrasound-guided paramedian sagittal oblique approach for neuraxial blockade is technically demanding. Innovative technologies have been developed to improve nerve identification and the accuracy of needle placement. The aim of this study was to evaluate three types of ultrasound scans during ultrasound-guided epidural lumbar punctures in a spine phantom. METHODS: Eleven sets of 20 ultrasound-guided epidural punctures were performed with 2D, GPS, and multiplanar ultrasound machines (660 punctures) on a spine phantom using an in-plane approach...

Parturients with super-morbid obesity, defined as body mass index greater than 50kg/m(2), represent a growing segment of patients who require anesthetic care for labor and delivery. Severe obesity and its comorbid conditions place the parturient and fetus at greater risk for pregnancy complications and cesarean delivery, as well as surgical and anesthetic complications. The surgical approach for cesarean delivery in these patients may require a supra-umbilical vertical midline incision due to a large pannus...

BACKGROUND: Intraspinal drug delivery therapy has been increasingly used in patients with intractable, nonmalignant pain who have failed to respond to conventional treatment or cannot tolerate systemic opioid(s) due to adverse events. By infusing a small dose of an opioid analgesic directly into the cerebrospinal fluid, near opioid receptors, profound spinal analgesia can be obtained. Before the implantation of permanent intraspinal pump, a neuraxial opioid infusion trial is usually conducted to demonstrate the effectiveness of neuraxial opioid for analgesia...

BACKGROUND: We describe three patients who received lumbar epidural steroid injections (LESI) for lumbosacral radicular pain that resulted in worsening of their symptoms. The procedures were performed following a review of remote diagnostic imaging studies. These cases demonstrate the lack of consensus in pain management domains for how to approach the workup and treatment of persistent/chronic low back pain, with a noted fragmentation in pain management strategies and applied therapies...

Pre-procedural ultrasound imaging of the spine to identify the interspinous and interlaminar space has been shown to facilitate subsequent performance of lumbar neuraxial blockade. However, adequate visualization of the vertebral canal can be challenging for less-experienced operators, and particularly in subjects with difficult anatomy. In this case report, we describe a simplified technique of ultrasound-assisted neuraxial blockade that addresses these limitations and may thus be a useful fallback option...

Neurological complications after labor and delivery are most often caused by compressive trauma related to childbirth and rarely related to neuraxial anesthesia/analgesia. However, it is important for anesthesiologists to be able to recognize the common manifestations of these neuropathies in order to distinguish them from more ominous causes of neurologic disease. In this article, we review the anatomy and etiology of postpartum thoracolumbar spinal cord, lumbar nerve roots, plexus, and lower extremity peripheral nerve injuries...

Treatment for rib fracture pain can be broadly divided into pharmacologic approaches with oral and/or parenteral medication and interventional approaches utilizing neuraxial analgesia or peripheral nerve blocks to provide pain relief. Both approaches attempt to control nociceptive and neuropathic pain secondary to osseous injury and nerve insult, respectively. Success of treatment is ultimately measured by the ability of the selected modality to decrease pain, chest splinting, and to prevent sequelae of injury, such as pneumonia...

Leptomeningeal cancer dissemination is a metastatic complication with growing impact in clinical oncology. Advances in treatment have been hampered by difficulties in diagnosis and response assessment, and nihilistic attitudes of physicians due to the poor prognosis, even when treating patients. However, relevant advances in therapeutic management have been achieved. In selected patients, survival and time to neurological progression can be improved with therapy, although an early diagnosis is critical (hence the importance of a high suspicion index)...

BACKGROUND: Lumbar discectomy surgery is a common neurosurgical procedure. Neuraxial labor analgesia may be less effective in parturients with a history of discectomy surgery because of postsurgical scarring and anatomical distortion. In this prospective observational case-controlled study, we compared bupivacaine consumption per hour of labor analgesia as an indirect measure of labor analgesic effectiveness between women with prior discectomy surgery and those who did not have back surgery...

OBJECTIVES: The use of ultrasound to guide peripheral nerve blocks is now a well-established technique in regional anaesthesia. However, despite reports of ultrasound guided epidural access via the paramedian approach, there are limited data on the use of ultrasound for central neuraxial blocks, which may be due to a poor understanding of spinal sonoanatomy. The aim of this study was to define the sonoanatomy of the lumbar spine relevant for central neuraxial blocks via the paramedian approach...

Globoid cell leukodystrophy (GLD) is a devastating lysosomal storage disease caused by deficiency of the enzyme galactocerebrosidase (GALC). Currently, there is no definite cure for GLD. Several attempts with CNS-directed gene therapy in twitcher mice (a murine model of GLD) demonstrated restricted expression of GALC activity in CNS and failure of therapeutic efficacy in cerebellum and spinal cord, resulting in various degrees of correction of biochemical, pathological and clinical phenotype. More recently, twitcher mice receiving a combination of hematopoietic and viral vector gene transfer therapies were not protected from neurodegeneration and axonopathy in both cerebellum and spinal cord...

REVIEW
Ki Jinn Chin, Manoj Kumar Karmakar, Philip Peng
The role of ultrasound in central neuraxial blockade has been underappreciated, partly because of the relative efficacy of the landmark-guided technique and partly because of the perceived difficulty in imaging through the narrow acoustic windows produced by the bony framework of the spine. However, this also is the basis for the utility of ultrasound: an interlaminar window that permits passage of sound waves into the vertebral canal also will permit passage of a needle. In addition, ultrasound aids in identification of intervertebral levels, estimation of the depth to epidural and intrathecal spaces, and location of important landmarks, including the midline and interlaminar spaces...

PURPOSE: The objective of this continuing professional development module is to describe the role of ultrasound for spine demarcation before placement of neuraxial blocks and to provide a comprehensive systematic approach towards ultrasound scanning in obstetric patients. PRINCIPAL FINDINGS: Ultrasound imaging of the lumbar spine has been shown to be effective in improving the success rate of neuraxial blocks in obstetric patients. The success rate of ultrasound-guided epidural insertions at first attempt was found to be 30-60% greater when compared with the traditional epidural method...

PURPOSE: Postauricular, transpetrous, presigmoid approach combines a supra/infratentorial exposure with partial petrosectomy to access third to the twelfth cranial nerves and extraaxial lesions situated anterolateral to brainstem. It provides a shorter working distance to large petrosal, petroclival, cerebellopontine, and cerebellomedullary cisternal lesions and their extensions to the subtemporal-infratemporal areas. This study reviews the surgical technique, corridors of extension, and complications encountered utilizing this approach for excising extensive lesions in these locations...

BACKGROUND AND OBJECTIVES: Spinal ultrasound offers valuable information to facilitate the placement of lumbar neuraxial anesthesia. Lumbar spine sonograms are unique, and aspects may appear atypical at times, particularly the ligamentum flavum (LF). The objective of this study was to describe the sonoanatomy of the lumbar spine and to determine the frequency of atypical images of the LF in pregnant women at term. METHODS: Using a 2-5 MHz curvilinear transducer, we imaged all the lumbar interspaces in the left and right paramedian longitudinal and transverse planes...

Amyotrophic lateral sclerosis (ALS) is characterized by progressive loss of spinal lower motoneurons. Gene delivery is a promising strategy to deliver therapeutic molecules to these vulnerable cells. However, definition of an optimal route of delivery capable of accessing neurons over a considerable extent of the neuraxis represents a significant logistical problem. Intramuscular vector injections are not ideal as this approach would involve hundreds of injections to completely treat an ALS patient and also would be dependent on retrograde transport of the viral platform of choice...
