Study Design: Retrospective chart audits.
Objective: To investigate the optimal timing at which permanent complete cervical spinal cord injury (CSCI) can be confirmed when evaluating paralysis caused by traumatic CSCI.
Setting: Department of Orthopedic Surgery, Spinal Injuries Center, Japan.
Article Synopsis
- The study was a prospective cohort design conducted at a Spinal Injuries Center in Japan, focusing on changes in swallowing difficulties (dysphagia) after acute cervical spinal cord injury (CSCI).
- Researchers evaluated the severity of dysphagia using standardized scales at various intervals post-injury, linking it to the extent of motor impairment experienced by patients.
- Results showed that dysphagia was most severe immediately after injury but improved over time, with greater swallowing difficulties observed in individuals with more significant paralysis.
Introduction: Compressive-flexion type cervical spine fracture is typically accompanied by apparent dislocation of the facet joints, undesirable cervical alignment, and devastating neurological dysfunction, which provides strong rationale for rendering prompt operative treatment. However, the validity of conservative treatment for compressive-flexion cervical spine injury in cases with preserved congruity of the facet joints has yet to be elucidated. The purpose of this study is to evaluate the long-term outcome of cervical alignment following conservative treatment for compressive-flexion cervical spine injury with preserved congruity of the facet joints.

Objective: To indicate the appropriate baclofen dosage to control severe spasticity of spinal origin and to develop the optimal administration protocol for long-term intrathecal baclofen (ITB) therapy.
Setting: Department of Orthopaedic Surgery, Spinal Injuries Center, Japan.
Article Synopsis
- The study investigates how cervical spinal canal stenosis (CSCS) affects neurological recovery after a traumatic cervical spinal cord injury (CSCI) in patients without major fractures or dislocations.
- Researchers analyzed 58 individuals using MRI imaging to assess the size of the cerebrospinal fluid (CSF) column and any potential links to motor function recovery.
- Findings indicated no significant connection between the size of the CSF column and neurological outcomes, suggesting that decompression surgery may not be necessary for these types of injuries, even with pre-existing CSCS.
Study Design: Retrospective review.
Objective: To evaluate the influence of static compression factors and dynamic factors based on the various degrees of traumatic force on the cervical spinal cord injury (SCI) in patients with ossification of the posterior longitudinal ligament.
Summary Of Background Data: Spinal cord disorder occurs as a result of various factors, including static factors and traumatic force.
Purpose: The purpose of the study was to evaluate the clinical relationship between cervical spinal canal stenosis (CSCS) and incidence of traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation, and to discuss the clinical management of traumatic CSCI.
Methods: Forty-seven patients with traumatic CSCI without major fracture or dislocation (30 out of 47 subjects; 63.83 %, had an injury at the C3-4 segment) and 607 healthy volunteers were measured the sagittal cerebrospinal fluid (CSF) column diameter at five pedicle and five intervertebral disc levels using T2-weighted midsagittal magnetic resonance imaging.
Analysis of the risk factors for tracheostomy in traumatic cervical spinal cord injury.
Spine (Phila Pa 1976)
December 2012
Study Design: A retrospective, consecutive case series.
Objective: To determine the risk factors that have a statistically significant association with the need of tracheostomy in patients with cervical spinal cord injury (CSCI) at the acute stage.
Summary Of Background Data: Respiratory complications remain a major cause of further morbidity and mortality in patients with CSCI.
Article Synopsis
- This study was a retrospective analysis focused on soft-tissue damage in patients with traumatic cervical spinal cord injury (SCI) that did not involve major bone injuries.
- It examined 88 adult patients using imaging techniques within days after trauma to assess the relationship between magnetic resonance imaging (MRI) findings and clinical outcomes.
- Results showed that damage to the anterior longitudinal ligament and intervertebral discs were common, and these MRI abnormalities were linked to initial spinal instability and neurological status, suggesting a clinical relevance to the observed injuries.
Study Design: The lumbar intervertebral discs of 135 subjects after autopsy were immunostained with antihuman heat shock protein 27 (HSP27) monoclonal antibody and antihuman heat shock protein 72 (HSP72) polyclonal antibody.
Objectives: To present the data on metabolic changes that occurred in the chondrocytes of intervertebral discs during development and aging.
Summary Of Background Data: Heat shock proteins have been implicated in the progressive degeneration of articular cartilage in joint disease, such as rheumatoid arthritis and osteoarthritis.
