Objective: Histopathological examination of the effects of Tisseel, Cova, Glubran and Coseal, which are used for sealing purposes in spinal surgery practice, on epidural fibrosis is aimed.
Methods: Forty Sprague Dawley rats were randomly divided into five groups in our study as Group 1 (n=8) control group (Laminectomy); Group 2 (n=8) Cova group (Laminectomy + Cova); Group 3 (n=8) Tissel group (Laminectomy + Tisseel); Group 4 (n=8) Coseal group (Laminectomy + Coseal); and Group 5 Glubrane group (Laminectomy + Glubrane). Control group was only applied laminectomy. After laminectomy to other groups, Cova was applied to the 2nd group, Tissel to the 3rd group, Coseal to the 4th group and Glubran to the 5th group in surgical fields. After the rats were monitored in separate cages for 6 weeks after the operation, the relevant spinal level was extracted and the samples were examined histopathologically and the results were evaluated statistically.
Results: It was found that there was a statistically significant difference in Tisseel and Glubran groups in terms of fibrosis grading compared to the control group, and this had a positive effect on fibrosis. Compared to the control group, there was no statistically significant difference on fibrosis in Cova and Coseal groups.
Conclusion: As dura adhesive agents used in spinal surgery practice did not increase spinal epidural fibrosis statistically significantly, we concluded that these products can be used safely during spinal surgery if necessary.

: This study aims to retrospectively detect associations with postoperative complications in spinal surgeries during the hospitalization period using standardized, single-center data to validate a method for complication detection and discuss the potential future use of generated data. : Data were generated in 2006-2019 from a standardized, weekly complications conference reviewing all neurosurgical operations at the University Hospital Luebeck. Paper-based data were recorded in a standardized manner during the conference and transferred with a time delay of one week into a proprietary complication register.

Objective: The aim of this study was to assess the effectiveness of a postoperative multimodal pain control protocol on perioperative pain scores in children undergoing decompression for Chiari type I malformation (CM-I).
Methods: This retrospective matched cohort study included patients < 21 years of age who underwent elective suboccipital craniectomy and C1 laminectomy for CM-I with or without duraplasty at a single center from January 2020 to July 2023. A standardized, multimodal postoperative pain protocol was implemented in August 2021 that did not use narcotic patient-controlled analgesia.
The Importance of Preserving the Posterior Ligament Complex in Elective Lumbar Fusion Surgery: Early Results from a Single-Center Experience.

Department of Neurosurgery, Swedish Neuroscience Institute, Seattle, USA.
Background: Adjacent segment disease (ASD) is a degenerative condition at the segment adjacent to a previously fused segment. Potential risk factors for ASD, such as posterior ligamentous complex (PLC) integrity between the upper instrumented vertebra (UIV) and the first unfused segment (UIV+1), have not been addressed. The objective of this study is to assess the PLC integrity between the UIV and UIV+1 following posterior lumbar decompression and fusion (PLDF).

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.

Multilevel lumbar spinal stenosis (LSS) is a prevalent degenerative condition characterized by lower back pain, intermittent claudication, and radicular leg pain. It ranks as one of the primary indications of spinal surgery in patients aged 65 and older. In this study, we aim to compare single-level and multilevel approaches for decompression alone in LSS considering the incidence of complications, reduction in pain score, and rates of surgical revisions.
