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 surgical treatment of subaxial acute cervical spine facet dislocations in adults: a systematic review and meta-analysis.

Adult cervical spine traumatic facet joint dislocations occur when excessive traumatic forces displace the vertebrae's facets, leading to loss of joint congruence. Reduction requires either cranial traction or open surgical procedures. This study aims to appraise the effects of different surgical techniques in the treatment of subaxial cervical spine acute traumatic facet blocks in adults.

Review of best classification systems for diagnosing and treating thoracolumbar spine trauma.

Background: Improved thoracolumbar spine trauma classification (TLSTC) systems can better help diagnose and treat thoracolumbar spine trauma (TLT). Here, we identified the types of injury (rationale and description), instability criteria, and treatment guidelines of TLSTC.

Methods: We used the PubMed/MEDLINE database to assess TLSTC according to the following variables: injury morphology, injury mechanism, spinal instability criteria, neurological status, and treatment guidelines.

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.

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.

The effect of posterior fossa decompression in adult Chiari malformation and basilar invagination: a systematic review and meta-analysis.

Chiari malformation (CM) and basilar invagination (BI) are mesodermal malformations with disproportion between the content and volume of posterior fossa capacity and overcrowding of neural structures at the level of foramen magnum. Several alternatives for posterior approaches are available, including extradural (ED), extra-arachnoidal, and intradural (ID) approaches. The objectives are to evaluate the effect of several surgical techniques for posterior fossa decompression (PFD) in the outcomes of patients with CCJM and to evaluate complications in the techniques reported.

Reliability of the evaluation of posterior ligamentous complex injury in thoracolumbar spine trauma with the use of computed tomography scan.

Purpose: The AOSpine thoracolumbar (TL) spine injury classification system is based mainly on computed tomography (CT). The main purpose of this study was to evaluate the reliability of CT scan in the diagnosis of posterior ligamentous complex (PLC) injury in thoracolumbar spine trauma (TLST).

Methods: We performed a cross-sectional study of 43 patients with TLST.

Is there a benefit to operating on patients (bedridden or in wheelchairs) with advanced stage cervical spondylotic myelopathy?

Surgical treatment of cervical spondylotic myelopathy (CSM) aims to prevent or delay the progression of the disease. Many patients are diagnosed in advanced stages of the disease, presenting severe functional disability and extensive radiologic changes, which suggests clinical irreversibility. There are doubts about the real benefit of surgery in patients who are seriously ill, bedridden or in a wheelchair.

Paraparesis or incomplete paraplegia? How should we call it?

Introduction: The neurological examination terminologies and definitions of the status of spinal cord injured (SCI) patients are of great importance to establish scales and provide standard nomenclatures. There is a disagreement between the classical neurological terminology and the definitions of complete and incomplete paraplegia that have been proposed in traumatic spinal cord injured patients.

Objective: To discuss the adequacy and the impact of the terms incomplete paraplegia and paraparesis in current literature.
