Disease relevance of Lumbosacral Plexus


High impact information on Lumbosacral Plexus

  • Unilateral analgesia following injection of fentanyl into the lumbosacral plexus [4].
  • Accumulating evidence, however, suggests that the far-field potentials of P17 and P31 arise from the distal portion of the sacral plexus and brainstem respectively [5].
  • We have examined the safety, tolerability, and efficacy of two intravenous doses of magnesium sulfate in 12 patients with neuropathic pain due to malignant infiltration of the brachial or lumbosacral plexus [6].
  • However, lumbar plexus block (three-in-one) with continuous bupivacaine infusion was most effective, and, although it constitutes an added technique, its scant complications and easy performance make its use advisable [7].
  • In this case series, patients were sedated with propofol alone and had a lumbar plexus block performed at the end of surgery [8].

Gene context of Lumbosacral Plexus

  • Measurements were made between the branches of the lumbar plexus and various bone landmarks such as the midline vertebral bodies, supracristal plane--a horizontal line connecting the superior-most aspect of the left and right iliac crests approximating the LA-5 vertebrae--and anterior superior iliac spine (ASIS) [21].
