Background: White cord syndrome (WCS) refers to the observation of intramedullary hyperintensity due to edema/ischemia and swelling on postoperative T2-weighted MRI sequences in the setting of unexplained neurological deficits after cervical spinal cord decompression. Pathophysiologically, WCS/reperfusion injury (RPI) occurs due to oxygen derived free radicals as a result of acute reperfusion or direct trauma from blood flow itself. Intraoperative neurophysiologic monitoring (IONM) can give early warning and detect neurologic deficits.

Article Synopsis
  • Coronal malalignment (CM) in adult spinal deformity (ASD) can lead to pain and functional issues, but it has been less studied compared to sagittal malalignment; the study aimed to establish a reliable classification system for CM among spine surgeons.
  • Fifteen readers assessed 28 CM cases using various radiographs, and intra-rater reliability scores were high, indicating strong consistency among readers; inter-rater reliability varied, showing some readers disagreed more than others.
  • The Obeid-CM classification demonstrated good reliability for categorizing CM, suggesting that surgeons should evaluate both sagittal and coronal alignment to enhance surgical decisions, even though side bending radiographs only slightly helped in understanding specific

Background Context: Proximal junctional failure (PFJ) is a common and dreaded complication of adult spinal deformity. Previous research has identified parameters associated with the development of PJF and the search for radiographic and clinical variables continues in an effort to decrease the incidence of PFJ. The lordosis distribution index (LDI) is a parameter not based on pelvic incidence.

Study Design: This is a retrospective analysis.

Objective: The purpose of this study was to compare the clinical, radiographic, and perioperative complication profiles of performing an interbody and posterior arthrodesis (CAGE) versus posterolateral lumbar fusion (PLF) alone in patients undergoing surgery for degenerative spondylolisthesis (DS).

Summary Of Background Data: DS is a common disorder that, failing nonoperative treatment, may be managed with surgical decompression and concomitant posterior arthrodesis.

The discovery of unique autoantibodies has informed and altered our approach to the diagnosis and management of the inflammatory myopathies. This study reports the initial clinical experience of use of the Extended Myositis Antibody (EMA) panel in the largest university teaching hospital in Ireland. We conducted a retrospective review of all patients who had serum samples tested for myositis specific antibodies and myositis associated antibodies from April 2014 to March 2015.
