Overview

Retrospective cohort study shows better alignment in open reduction, suggesting reduction quality is crucial for reducing nonunion rates.

Key Points

  • This study aims to compare open and closed reduction techniques in treating subtrochanteric femur fractures.
  • Retrospective cohort study including 114 patients with subtrochanteric fractures treated surgically.
  • Open reduction defined as requiring an incision ≥3cm, assessed via modified Baumgaertner criteria.
  • Outcomes analyzed included delayed union and nonunion using statistical methods like Kaplan-Meier survival analysis.
  • Acceptable reduction achieved more often in the open group (94.9% vs. 68.0%; p=0.001).
  • Mean time to union was shorter in open reduction (18.2 weeks) but not significant (p=0.055).
  • Reduction quality was a strong predictor of outcomes; acceptable reductions led to faster union (p<0.001) and lower rates of nonunion.
