Iatrogenic spinal cord herniation is a rare complication following spinal stabilization surgery. The authors present a case of circumferential thoracic tumor decompression and fixation by anterior instrumentation complicated by delayed anterior spinal cord herniation. This complication resulted in progressive paraparesis 5 years after the original procedure. The patient underwent reexploration and repair of the dural defect, resulting in the reduction of the spinal cord to its normal position. The patient's paraparesis improved significantly after dural repair. Although progression of neurological deficit can be very slow, repair of the dural defect can restore normal spinal cord alignment and improve neurological deficit. To the best of the authors' knowledge, this is the first reported case of spinal cord herniation following an anterior thoracic vertebrectomy.

Postvoid Residual Volume Correlates With Bladder Outlet Obstruction and Not With Detrusor Contraction Strength Parameters in Women: A Matched Case-Control Study.
Int Neurourol J
December 2024
Department of Urology, Moinhos de Vento Hospital, Porto Alegre, Brazil.
Purpose: To compare voiding parameters in women with and without increased postvoid residual (PVR) volume, to correlate these parameters with PVR volume and PVR percentage, and to describe their ability to predict an increased PVR volume.
Methods: Retrospective cross-sectional study of urodynamics data prospectively acquired from consecutive symptomatic women over a 5-year period. Patients with spinal cord disorders and with abdominal straining during voiding (abdominal pressure ≥10 cm H2O over baseline at maximum flow rate [Qmax]) were excluded.
Purpose: Neurogenic lower urinary tract dysfunction (NLUTD) is highly prevalent among patients with neurologic disorders. Some studies have demonstrated that implantable neuromodulation can improve symptoms of NLUTD. We seek to describe our experience with sacral and pudendal neuromodulation in patients with NLUTD.

Spinal cord injuries (SCIs) can lead to severe neuropathic pain and increased risk of myocardial infarction and heart failure; therefore, the use of analgesics against SCI-induced pain should be minimized because of their adverse effects on the cardiovascular system. Ivabradine, a blocker of hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels, is used as a bradycardic agent, but recent studies focused on it as an analgesic agent for peripheral neuropathic pain. However, the analgesic effects of ivabradine on central neuropathic pain, such as SCI-induced pain, have not been examined.

Our extensive basic research on photodynamic therapy (PDT) application in models of intracranial malignant astrocytoma led to its clinical application for intracranial malignant astrocytoma in Japan. Having considered the safety and effectiveness of this pathology, we initiate a first-in-human clinical study of PDT for spinal cord malignant astrocytoma. This study has an open-label, single-arm design.

Department of Neurosurgery, Spine and Spinal Cord Institute, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea.
Objective: We aimed to investigate the incidence of delayed-onset neurological deficits (DONDs), DOND-related reoperation rates following adult spinal deformity (ASD) surgery, and efficacy of transverse process hooks (TPHs) at the uppermost instrumented vertebra (UIV) compared to pedicle screws (PSs).
Methods: We included 90 consecutive patients who underwent instrumented fusion from the sacrum to the distal thoracic spine for ASD, with a minimum follow-up of 24 months. Clinical and radiological outcomes were compared between 33 patients in the TPH group and 57 patients in the PS group, using the Scoliosis Research Society-22 Outcomes questionnaire (SRS-22), Medical Outcomes Study Questionnaire Short-Form 36 (SF-36), and various spinal sagittal parameters.
