Osteoarthritis burden and inequality from 1990 to 2021: a systematic analysis for the global burden of disease Study 2021.

Osteoarthritis (OA) is a major global health burden, affecting millions and causing significant disability. Understanding its trends and determinants is crucial for effective management and prevention. We analyzed data from the Global Burden of Diseases (GBD) study 2021 to assess OA incidence, Years Lived with Disability (YLDs), and age-standardized rates (ASIR/ASYR) from 1990 to 2021.

The correlation between intraoperative saline irrigation volume and postoperative drainage volume and short-term efficacy in single-level posterior lumbar interbody fusion.

Background: This study aimed to explore: (I) the effect of different intraoperative saline irrigation volumes on postoperative drainage volume, drainage tube removal time, and short-term efficacy in single-level posterior lumbar interbody fusion (PLIF); and (II) the recommended intraoperative saline irrigation volume.

Methods: A total of 120 patients with lumbar degenerative diseases who underwent single-level PLIF between January 2013 and December 2019 were enrolled. Based on the average total postoperative drainage volume, the patients were divided into 2 groups: group A (total postoperative drainage ≤103.
