BACKGROUND: Cauda equina syndrome (CES) is a consequence of a variety of etiologies. CES is most commonly due to compression of the thecal sac and nerve roots by a massive disc herniation. However, it rarely presents secondary to aortic occlusion. Aortoiliac occlusive disorder is usually associated with chronic claudication, erectile dysfunction, and diminished lower limb pulses. Acute aortic occlusion, however, is associated with serious complications such as spinal cord infarction and ischemia...

BACKGROUND: Here, we assessed a new trajectory and insertion torque for the placement of a long lateral mass screw (LLMS) that offers stronger posterior fixation versus a shorter lateral mass screw (LMS) in the posterior cervical spine. We report a short technical note of the insertion torque of LLMS. METHODS: The insertion trajectory/torque was evaluated in 30 patients (10 males and 20 females) undergoing posterior cervical LLMS fusions (2021-2023). Patients averaged 65 years of age...

DESIGN: Prospective diagnostic study. OBJECTIVES: Anatomical evaluation and graduation of the severity of spinal stenosis is essential in degenerative cervical spine disease. In clinical practice, this is subjectively categorized on cervical MRI lacking an objective and reliable classification. We implemented a fully-automated quantification of spinal canal compromise through 3D T2-weighted MRI segmentation. SETTING: Medical Center - University of Freiburg, Germany...

PURPOSE: This study compared the recovery of motor function and the safety of early and delayed surgical intervention in patients with central cord syndrome (CCS). METHODS: PubMed, Embase, Cochrane Library, and Web of Science were employed to retrieve the targeted studies published from inception to February 19, 2023. Comparative studies of early versus delayed surgical decompression in CCS based on American Spinal Injury Association motor score (AMS) recovery, complication rates, and mortality were selected...

BACKGROUND: Thoracic spinal cord injury after posterior cranial fossa surgery in younger patients is a rare complication. There have been reports of this complication in tumor and spine fields but not in vascular surgery. OBSERVATIONS: A 22-year-old-man experienced cerebellar arteriovenous malformation rupture, and the malformation was surgically removed with the man in the Concorde position. After surgery, the man had severe paraplegia, and a thoracic spinal cord injury was diagnosed...

OBJECTIVE: To explore the clinical efficacy and advantages of laparoscopic inguinal lymphadenectomy (IL) with preservation of the great saphenous vein through subcutaneous approach via umbilical cord for the treatment of penile carcinoma patients. METHODS: The data of 27 patients with penile cancer underwent the laparoscopic inguinal lymph adenectomy with preservation of the great saphenous vein through subcutaneous via umbilical cord approach in the General Hospital of Eastern Theater Command from 2014 May to 2022 May were analyzed retrospectively...

BACKGROUND: Anterior cervical discectomy and fusions (ACDF) are among the most common cervical spine operations, with over 137,000 surgeries performed annually. Understanding reasons underlying malpractice pertaining to ACDF may inform physicians of practices to improve delivery of patient care and mitigate malpractice. The aim of our study was to analyze the causes and outcomes for lawsuits pertaining to ACDF. METHODS: The Westlaw Edge and Verdict Search databases were queried for malpractice claims utilizing the keywords "anterior cervical discectomy and fusion" and "ACDF"...

BACKGROUND: Failed back surgery syndrome (FBSS) is a common and incapacitating condition affecting patients with previous spine surgery in whom treatment approach can be challenging. This study aimed to summarize existing secondary studies and up-to-date randomized clinical trials (RCTs) that assess the effectiveness of available treatment options for FBSS. METHODS: Systematic searches were carried out in five databases (PubMed, Cochrane, Scielo, Epistemonikos, and Google scholar) for all systematic reviews on the effectiveness of treatment options for FBSS published after 2012...

This study describes a patient with an intradural extramedullary (IDEM) tumor removed entirely using the unilateral biportal endoscopic technique (UBE), achieving satisfactory clinical outcomes. A 60-year-old woman had a diagnosis of meningioma with sensations and motor dysfunction in the lower extremities and perineum and gait disturbances for three years, which has worsened over the last month. Preoperative imaging data showed a sizeable IDEM tumor at the T10 level, significantly compressing the thoracic spinal cord to the right side, with 80% intraspinal encroachment...

This video article explores a case of tethered cord release through a minimally invasive biportal endoscopic approach. A 24-year-old female with chronic back pain and thigh numbness underwent surgery. The chosen approach involved biportal endoscopic technique, demonstrating precision with minimal bone excision. Preoperative imaging revealed a midline fusion defect at L5 and abnormal conus medullaris termination. The surgical procedure involved one-sided hemilaminectomy, durotomy, and careful filum terminale separation...

INTRODUCTION: Persistent Spinal Pain Syndrome (PSPS) refers to chronic axial pain and/or extremity pain. Two subtypes have been defined: PSPS-type 1 is chronic pain without previous spinal surgery and PSPS-type 2 is chronic pain, persisting after spine surgery, and is formerly known as Failed Back Surgery Syndrome (FBSS) or post-laminectomy syndrome. The etiology of PSPS-type 2 can be gleaned using elements from the patient history, physical examination, and additional medical imaging...

BACKGROUND CONTEXT: Intraoperative neurophysiological monitoring (IONM) is used to reduce the risk of spinal cord injury during pediatric spinal deformity surgery. Significant reduction and/or loss of IONM signals without immediate recovery may lead the surgeon to acutely abort the case. The timing of when monitorable signals return remains largely unknown. PURPOSE: The goal of this study was to investigate the correlation between IONM signal loss, clinical examination, and subsequent normalization of IONM signals after aborted pediatric spinal deformity surgery to help determine when it is safe to return to the operating room...

Blast is the most common injury mechanism in conflicts of this century due to the widespread use of explosives, confirmed by recent conflicts such as in Ukraine. Data from conflicts in the last century such as Northern Ireland, the Falklands and Vietnam up to present day, show between 16 and 21% of personnel suffered a traumatic brain injury. Typical features of fatal brain injury to those outside of a vehicle (hereafter referred to as dismounted) due to blast include the presence of haemorrhagic brain injury alongside skull fractures rather than isolated penetrating injuries more typical of traditional ballistic head injuries...

OBJECTIVES: Lumbar spine surgery is a common procedure for treating disabling spine-related pain. In recent decades, both the number and cost of spine surgeries have increased despite technological advances and modification in surgical technique. For those patients that have continued uncontrolled back and/or lower extremity pain following lumbar spine surgery, spinal cord stimulation (SCS) has emerged as a viable treatment option. However, the impact of lumbar spine surgical history remains largely unstudied...

Occult spinal dysraphisms (OSDs) are caused by various defects in the embryogenesis of the spinal cord and represent an obstacle to the ascent of the conus, which allows the conus to pass from the lower levels of the spinal canal to the final position between L1 and L2 during normal foetal life. When an OSD tethers the spinal cord at the lower levels, it can lead to neurological symptoms, better known as tethered cord syndrome. Surgical treatment of OSD is primarily aimed at untethering the spinal cord. In asymptomatic patients, this can protect against the long-term development of neurological deficits...

PURPOSE: To propose a novel surgical strategy-thoracic anterior controllable ante-displacement fusion (TACAF) to treat mT-OPLL, and investigated its safety and efficacy. METHODS: Between January 2019 and December 2021, a total of 49 patients with thoracic myelopathy due to mT-OPLL were surgically treated with TACAF were retrospectively reviewed. Patients' demographic data, radiological parameters, and surgery-related complications, m-JOA and VAS scores, thoracic kyphosis (TK), kyphosis angle in fusion area (FSK), thoracic curvature, spinal cord curvature and curvature of curved rod in surgical region, diameter and area of the spinal cord at the most compressed level were included...

OBJECTIVE: Chiari malformations (CMs) are a group of congenital or acquired disorders characterized by hindbrain overcrowding into an underdeveloped posterior cranial fossa. CM is considered largely sporadic-however, there exists growing evidence of transmissible genetic underpinnings. The purpose of this systematic review of all familial studies of CM was to investigate the existence of an inherited component and provide recommendations to manage and monitor at-risk family members. METHODS: This paper includes the following: 1) a unique case report of dizygotic twins who presented at the Toronto Western Hospital Spinal Cord Clinic with symptomatic CM type 1 (CM-1) and syringomyelia; and 2) a systematic review of familial CM...

INTRODUCTION: Cervical spine disease is a leading cause of pain and disability. Degenerative conditions of the spine can result in neurologic compression of the cervical spinal cord or nerve roots and may be surgically treated with an anterior cervical discectomy and fusion (ACDF) in up to 137,000 people per year in the United States. A common sequelae of ACDF is reduced cervical range of motion (CROM) with patient-based complaints of stiffness and neck pain. Currently, tools for assessment of CROM are manual, subjective, and only intermittently utilized during doctor or physical therapy visits...

Introduction : Preventing the development of postherpetic neuralgia (PHN), the most prevalent and severe complication of herpes zoster (HZ), is vital. Recently, it has been suggested that using temporary spinal cord stimulation (tSCS) for 10-14 days can improve HZ-associated pain (ZAP) and prevent PHN. However, myelitis complicates HZ. Permanent SCS has been successful in treating neuropathic pain induced by postoperative transverse myelitis of the spine that has not responded to traditional multidisciplinary treatment...

We report a case of acute spinal cord infarction treated with intravenous (IV) thrombolysis at seven hours from symptom onset. Nineteen previously thrombolysed cases are reviewed. The patient underwent a clinical assessment, followed by an MRI of the spine. He was thrombolysed with a recombinant tissue plasminogen activator. Neurological severity was assessed at presentation and 24 hours using the National Institute of Health Stroke Scale (NIHSS), and disability at three months was evaluated using a modified Rankin scale (mRS)...
