Background: Posterior laminectomy is a standard treatment for thoracic ossification of the ligamentum flavum (TOLF), but it often leads to neurological deterioration during surgery. This study aimed to reduce iatrogenic neurological deterioration by using an S8 navigation system combined with an ultrasonic osteotome for three-dimensional real-time dynamic visualization decompression.
Methods: A retrospective analysis was conducted on patients who underwent laminectomy and internal fixation for TOLF in our centre from January 2016 to January 2023.
Posterior Ligamentum Complex Preservation Alleviate ASD-Related Biomechanical Deterioration in Lumbar Interbody Fusion Models: A Finite Element Analysis.

Department of Orthopedics, Luzhou Key Laboratory of Orthopedic Disorders, The Affiliated Traditional Chinese Medicine Hospital Southwest Medical University Luzhou Sichuan Province People's Republic of China.
Background: There are differences in the extent of excision of articular processes, spinal processes and posterior ligamentum complexes (PLC) for posterior approach lumbar interbody fusion. Given that the biomechanical significance of these structures has been verified and that deterioration of the biomechanical environment is the main trigger for complications in both fused and adjacent motion segments, changes in decompression ranges may affect the potential risk of adjacent segmental disease (ASD) biomechanically; however, this topic has yet to be identified.
Methods: Posterior lumbar interbody fusion (PLIF) with different decompression strategies was simulated in a well-validated lumbosacral model.
Efficacy of Acetazolamide for Treatment of Iatrogenic, Traumatic, and Spontaneous Cerebrospinal Fluid Leaks of the Anterior Skull Base: A Systematic Review.

Neurological Surgery, University of Washington Medical Center, Seattle, USA.
A cerebral spinal fluid (CSF) leak from the anterior skull base is a challenging neurosurgical issue that requires prompt recognition and treatment. Options for treatment include medical and surgical repair. A systematic review was performed screening for both retrospective and prospective clinical studies evaluating the efficacy of acetazolamide in the event of CSF leaks of the anterior skull base.

Resident at Radiology Department, French Medical Institute for Mothers and Children (FMIC), Kabul, Afghanistan.
Iatrogenic intracranial hypotension is a known complication of spinal anesthesia that can lead to more severe conditions, such as dural or cerebral venous sinus thrombosis (CVST). This report presents a case of intracranial hypotension in a young woman after lumbar anesthesia for a cesarean section that was complicated by CVST and subsequently by lobar hemorrhage, clinically presenting with severe headache and seizures. The diagnosis was made via cerebral magnetic resonance (MR) imaging, and the patient was treated medically.
