Chamberlain's Line Violation in Basilar Invagination Patients Compared with Normal Subjects: A Systematic Literature Review and Meta-Analysis.

Objective: To compare the measured odontoid tip violation above Chamberlain's line described in the literature to diagnose basilar invagination (BI) and to establish the normal placement of the dens tip defining individuals without BI (normal subjects).

Methods: A systematic literature review was performed to identify clinical or radiological studies that expressed the amount of odontoid violation above Chamberlain's line in patients with a BI diagnosis. In addition, a meta-analysis was performed to evaluate normal subjects' values of Chamberlain's line violation (CLV).

The impact of traumatic herniated discs in cervical facets dislocations treatments: systematic review and meta-analysis.

Background: Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. This study's aim is an analysis of safety and efficacy when treating acute cervical traumatic facet dislocations using cranial-cervical traction or posterior open reduction and fixation in the presence of disc herniations.

Role of Atlas Assimilation in the Context of Craniocervical Junction Anomalies.

Atlas assimilation (AA) may be associated with atlantoaxial dislocation, Chiari malformation (CM), and basilar invagination. The importance of AA in the context of craniocervical junction (CVJ) anomalies is unclear. Considering this context, this study's objective is to discuss the role of AA in the management of CVJ anomalies, especially in CM.

Retro-odontoid pseudotumor: a poorly recognized alteration of the craniocervical junction.

Introduction: Retro-odontoid pseudotumor (ROP) is a rare disease that affects the atlantoaxial joint and, in general, is associated with local biomechanical alterations that may or may not cause instability.

Methods: Descriptive study of the literature available in databases MEDLINE/PubMed, LILACS, and Scopus. The research was conducted in April 2019.

The effect of filum terminale sectioning for Chiari 1 malformation treatment: systematic review.

Purpose: Symptomatic Chiari type I malformation (CM) is treated with posterior fossa decompression with/ without duroplasty. Few authors suggested cerebellar tonsil caudal migration due to a supposed "caudal traction" of cranial nerve structures in a so-called occult tethered cord syndrome. For these authors, filum terminale (FT) sectioning may improve CM symptoms.

Neuroprotective Agents as an Adjuvant Treatment in Patients With Acute Spinal Cord Injuries: A Qualitative Systematic Review of Randomized Trials.

Study Design: This was a systematic literature review.

Objective: The objective of this study was to evaluate randomized clinical trials that address potential neuroprotective agents used to improve neurological outcome in patients with spinal cord injury (SCI).

Summary Of Background Data: Clinical treatment of acute SCI has evolved significantly, but neurological recovery of severely injured patients remains modest.

Intraoperative Neurophysiological Monitoring in Spine Surgery: A Systematic Review and Meta-Analysis.

Study Design: Systematic literature review and meta-analysis.

Objective: The objective of this systematic literature review was to evaluate if intraoperative neurophysiological monitoring (IONM) can prevent neurological injury during spinal operative surgical procedures.

Summary Of Background Data: IONM seems to have presumable positive effects in identifying neurological deficits.

Management of Type II Odontoid Fractures: Experience from Latin American Spine Centers.

Objective: To analyze characteristics of type II odontoid fracture (TII-OF), including clinical and radiographic factors, that influence surgical planning in 8 Latin American centers.

Methods: Retrospective chart review was performed of 88 patients with TII-OF between 2004 and 2015 from 8 Latin American centers. Parameters studied included 1) demographic data and causes of TII-OF, 2) clinical and neurologic presentation, 3) characteristics of fracture (degree of odontoid displacement, displacement of odontoid relative to C2 body, anatomy of fracture line, distance between fragments, presence of comminution, contact area between odontoid and C2 body), 4) type of treatment, and 5) clinical and radiographic outcome.

The pathophysiology, classification, treatment, and prognosis of a spontaneous thoracic spinal cord herniation: A case study with literature review.

Background: Spinal cord herniation was first described in 1974. It generally occurs in middle-aged adults in the thoracic spine. Symptoms typically include back pain and progressive paraparesis characterized by Brown-Séquard syndrome.

Prognostic parameters and spinal metastases: a research study.

Object: To identify pre-operative prognostic parameters for survival in patients with spinal epidural neoplastic metastasis when the primary tumour is unknown.

Methods: This study was a retrospective chart review of patients who underwent surgery for spinal epidural neoplastic metastases between February 1997 and January 2011. The inclusion criteria were as follows: known post-operative survival period, a Karnofsky Performance Score equal to or greater than 30 points and a post-operative neoplastic metastasis histological type.

Management of metastatic spinal column neoplasms--an update.

The increased survival of cancer patients due to the improvement and advancement of therapeutic modalities has promoted progressive increase in the prevalence of metastatic tumors of the spine, making it important for healthcare professionals to acquire knowledge in the field. Spinal column metastases are usually secondary to malignant neoplasm of the breast, lung and prostate, male gender being the most often affected and pain being the initial symptom in 90% of patients. It is estimated that 30-90% of terminally ill patients with cancer have metastases at some spinal column segment.

[Effectiveness of methylprednisolone in the acute phase of spinal cord injuries--a systematic review of randomized controlled trials].

Unlabelled: Steroid therapy has been tested as a protector in spinal cord injury. Multicenter studies evaluating the methylprednisolone (MP) in post traumatic neurological recovery have shown promising results according to NASCIS. A large number of critical studies related to the NASCIS results have been published.

Basilar invagination: craniocervical instability treated with cervical traction and occipitocervical fixation. Case report.

The upward odontoid displacement observed in basilar invagination (BI) is generally associated with a horizontal clivus and craniocervical kyphosis, conditions that exert ventral compression at the spinomedullary junction. Ventral brainstem decompression by reduction or elimination of the odontoid invagination is part of the desired treatment. The authors describe a case of BI in an adult, who was effectively treated with the easy and safe reduction of odontoid invagination via cervical traction.
