The association between surgical start time and spine surgery outcomes.

Objective: Neurosurgical operations, including spine surgeries, often occur outside "normal business hours" due to the urgent or emergent nature of cases. This study investigates the association of surgical start time (SST) with spine surgery outcomes.

Methods: A retrospective cross-sectional study was performed using electronic health record data from a multi-hospital academic health system from 2017 to 2024.

The effect of chronic kidney disease on short-term single-level lumbar fusion outcomes.

Introduction: Chronic kidney disease (CKD) has an increasing global prevalence and has previously been associated with increased complications and morbidity after spine surgery. Understanding the isolated effect of CKD on short-term patient outcomes is critical for optimizing perioperative risk management and healthcare utilization.

Objective: The aim of this study is to utilize coarsened exact matching (CEM) to analyze the isolated effect of CKD on short-term patient outcomes in single-level posterior lumbar fusion surgery.
