We compared and analyzed the etiology, surgical events, outcomes, and complications among pediatric, adolescent, and adult patients who underwent PVCR in a single-center database retrospectively. Patients were categorized into pediatric (0-12 yr), adolescent (13-19 yr), and adult (>20 yr) cohorts.

Mid- and Long-Term Comparison Analysis of Two Approaches for the Treatment of Level III or Higher Lenke-Silva Adult Degenerative Scoliosis: Radical or Limited Surgery?

Objective: As the population in general is living longer, less invasive adult degenerative scoliosis (ADS) surgery that balances risks and benefits requires long-term clinical outcomes to determine its strengths and weaknesses.

Methods: In this retrospective study, 78 patients with ADS (Lenke-Silva levels III or higher), who accepted surgical treatment at our hospital between June 2012 and June 2019 were included.
