Key Points

  • The aim is to evaluate how body mass index affects surgical outcomes for grade 1 spondylolisthesis.
  • Analysis of surgery outcomes from the Quality Outcomes Database
  • Comparison of minimally invasive (MI) vs. open surgical approaches
  • Focus on patients with different BMI categories
  • Follow-up period of two years
  • Both surgical approaches led to patient improvement over time.
  • Patients with BMI ≥ 30 kg/m2 showed better outcomes with MI surgery.
  • No significant difference in outcomes noted for patients with BMI < 30 kg/m2.

Abstract

Regardless of approach, patients improved following surgery for grade 1 DLS. Patients with BMI ≥ 30 kg/m2 had better long-term outcomes when treated with an MI surgical approach versus open surgery. This difference in outcomes between MI and open surgery was not observed among patients with BMI < 30 kg/m2.
