PURPOSE: The three aims of this Spine Tango registry study of patients undergoing decompression for spinal stenosis were to: report the rate of dural tear (DT) stratified by treatment centre; find factors associated with an increased likelihood of incurring a DT; and compare treatment outcomes in relation to DT (none vs. repaired vs. unrepaired DT). METHODS: Multivariate logistic regression was used to assess the association between DT and patient and treatment characteristics...

Hypotensive anesthesia is utilized to reduce bleeding during orthopedic surgery. One of the various drugs that have been used to reduce blood pressure is remifentanil. This study was an attempt to compare the effect of remifentanil with that of electroacupuncture (EA) at DU20 on reducing blood pressure. In this randomized controlled clinical trial, 54 patients undergoing lumbar laminectomy were allocated to two groups. Hypotensive anesthesia was performed through infusion of remifentanil 100 μg/kg/min for the control group, and EA at DU20 acupoint with a frequency of 2-10 Hz and intensity of 1-5 mA for the intervention group...

The ventriculus terminalis (VT) is a small ependyma-lined cavity within the conus medullaris that is in direct continuity with the central canal of the spinal cord. Cystic dilatation of the ventriculus terminalis on its own is an extremely rare pathological event in adults whose pathogenesis is uncertain. VT has been described in children as a normal developmental phenomenon. These lesions are often diagnosed incidentally during imaging and are in most cases asymptomatic, especially in children. Symptomatic dilatation of VT in adults is a rare condition with 61cases being reported to date...

RATIONALE: Caudal epidural injection is one of the conventional treatments of chronic back pain. Even though spinal epidural hematoma after caudal epidural injection is rare but it can cause serious neurologic complication. PATIENT CONCERNS: An 83-year-old woman taking cilostazol received caudal epidural steroid injection because of her chronic back pain. Six hours later, she experienced an acute hip pain which worsened with time. DIAGNOSIS: Magnetic resonance image showed acute cord compression due to a spinal epidural hematoma at L2-S1 level with concomitant central canal compromise at L2/3, L3/4 level...

Surgery for adult spinal deformity (ASD) has emerged as an efficient treatment alternative, but it is fraught with potential perioperative morbidity, incompletely mitigated by emerging minimally invasive surgical techniques. In mild-to-moderate ASD balanced in the sagittal plane, there are situations in which the counterintuitive simple decompression through a foraminotomy or laminectomy, or even a short-segment fusion may be an attractive treatment. This article presents a case example and the authors' treatment rationale and reviews the limited available literature supporting it...

BACKGROUND: The "Analgesia Nociception Index" (ANI; MetroDoloris Medical Systems, Lille, France) is a proposed noninvasive guide to analgesia derived from an electrocardiogram trace. ANI is scaled from 0 to 100; with previous studies suggesting that values ≥50 can indicate adequate analgesia. This clinical trial was designed to investigate the effect of intraoperative ANI-guided fentanyl administration on postoperative pain, under anesthetic conditions optimized for ANI functioning...

Neurocysticercosis is a parasitic disease that results from the larvae of Taenia solium. While neurocysticercosis is considered as the most common parasitic infection of the nervous system, spinal neurocysticercosis is rare. The present case study investigated a 59-year-old woman, who was admitted to our hospital with pain in the bilateral lower limbs and urinary complaints in the form of straining of micturition with increasing frequency. Magnetic resonance imaging revealed an intradural extramedullary lesion extending from L1/2 to S1 of the spine...

INTRODUCTION: Pain is one of the most important reasons for the patients concern after surgery. The perfect sedative should have properties like rapid onset, least pain and adverse effects. AIM: To assess the effect of sevoflurane plus propofol on postoperative pain, haemodynamic stability and complication after lumbar disc surgery. MATERIALS AND METHODS: This was a randomized double- blind clinical trial. A total of 75 patients scheduled for elective lumbar disc surgery with simple random sampling design received sevoflurane (n=25, induced with Thiopentone and maintained with sevoflurane), propofol (n=25, induced and maintained with propofol) and sevoflurane plus propofol (n=25, induced with propofol and maintained with sevoflurane)...

Solitary plasmacytoma of the bone (SPB) is a rare plasma cell neoplasm representing only about 5% of plasma cell neoplasia. It usually presents as a lytic lesion mainly localized within the axial skeleton. SPB is exceedingly rare in young individuals, and only few cases have been reported so far in patients younger than 20 years of age. In view of rarity of disease, definitive treatment guidelines have not been established. We hereby report a case of SPB involving of lumbar vertebra (L5) in a 12-year-old boy...

Lumbar spinal stenosis is typically a degenerative condition that leads to compression of the spinal canal and lateral recess, resulting in leg pain and walking disability. Surgical management is indicated after failure of non-surgical management or rapidly worsening neurological impairment. The traditional approach is a laminectomy with foraminotomy and partial facetectomy but a newer minimally invasive option, unilateral laminectomy for bilateral decompression (ULBD), seems to demonstrate the better postoperative outcomes due to its unilateral exposure...

BACKGROUND: Our previous study demonstrated that selective nerve root block (SNRB) can influence decision-making in lumbar surgery by guiding the selection of nerve roots targeted for decompression in diagnostic doubt patients (DDPs). However, further studies were needed to determine whether this selective decompression (SD) procedure would result in similar clinical outcomes and reduce the perioperative parameters and postoperative complications as compared to the non-selective decompression (NSD) procedure...

Intradural spinal arachnoid cysts (ISACs) have been reported in the current literature as either an idiopathic disease or exceedingly rare sequelae after lumbar puncture, spinal trauma, or meningitis. Other studies have more appropriately termed the iatrogenic pathology as a spinal subdural extra-arachnoid hygroma (SSEH), as there is not often a clear cyst wall as in a true arachnoid cyst. However, to the best of our knowledge, none of the previous studies described an SSEH following uncomplicated posterior lumbar surgery, as they have previously involved clear durotomies during the initial operation...

Posterior decompression surgery which enlarges the spinal canal in cases with lumbar spinal stenosis is the most fundamental technique in spine surgery, but controversy still remains for the exact technique. Because nerve roots run under the ventral side on the superior articular process (SAP), achieving both facet joint preservation and nerve root decompression is problematic. In conventional laminotomies or laminectomies, medial facetectomies are performed to decompress the nerve root, but it is ideal to preserve the facet joints completely for preserving joint stability...
