Background: The transforaminal posterior approach (TLIF) procedure was first described in 1982. Current literature indicates its equality in outcomes for fusion constructs as other anterior-posterior procedures. As a procedure becomes more popular and is more frequently performed the types and number of complications that occur increase. We report on a two case series that underwent TLIF. Both patients had satisfactory postoperative imaging, but presented later with coronal plane vertebral body fractures in the caudal vertebral body of the TLIF construct. We believe the complication may be related to: (a) unrecognized fracture of the endplate during cage impaction; (b) overloading the endplates by maximizing the lordosis achieved by using the reverse jackknife position on a Jackson table; (c) underlying mineral bone disease in patients. As the TLIF procedure increases in popularity, caution should be exercised to avoid the same potential complications.
Purpose: To describe a potential complication with the TLIF procedure.
Study Design: Case report.
Patient Sample: 2.
Outcome Measure: Revision surgery.
Methods: Case series.
Results: Caudal vertebral body fracture is a potential complication after TLIF.
Conclusion: TLIF procedures can result in an unstable vertebral body fracture potentially necessitating revision decompression & stabilization. We recommend extra caution in patients with mineral bone disease, as technical errors can be magnified.

Introduction: The management of de novo non-specific spinal infections (spondylodiscitis - SD) remains inconsistent due to varying clinical practices and a lack of high-level evidence, particularly regarding the indications for surgery.
Research Question: This study aims to develop consensus recommendations for the diagnosis and management of SD, addressing diagnostic modalities, surgical indications, and treatment strategies.
Material And Methods: A Delphi process was conducted with 26 experts from the European Association of Neurosurgical Societies (EANS).

Purpose: Vertebral body tethering (VBT) is a non-fusion surgical option for adolescent idiopathic scoliosis (AIS) that requires a postoperative (PO) chest tube. This study evaluates whether 48 h of PO TXA reduces chest tube (CT) drainage and retention compared to 24 h of TXA following VBT for AIS.
Methods: Consecutively treated patients with a diagnosis of AIS who underwent VBT were assessed.
Preoperative myosteatosis and perioperative serum chloride levels predict 180 day major complications after radical cystectomy.

This study aimed to investigate the role of myosteatosis, sarcopenia, and perioperative serum biomarkers as independent predictors of major complications within 180 days following radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). We retrospectively analyzed of 127 MIBC patients who underwent RC between 2013 and 2023 at a single institution. Preoperative body composition was assessed using CT scans at the L3 vertebral level to measure psoas muscle density (PMD), skeletal muscle density (SMD), axial muscle density (AMD), and muscle indices.
