The Odds of Complications After Total Hip Replacement for Patients With and Without Previous Hip Fusion

OutcomeOdds ratio (with:without fusion)95% confidence interval
Girdlestone resection14.93.1–70.6
Complications during index admission63.1–11.5
  • An odds ratio > 1 implies that the complication is more likely to occur after conversion of a previous hip fusion. In all cases the estimate is adjusted for age, gender, diagnosis, comorbidity, admission year, follow-up time, and surgeon and hospital volume. All odds ratios are statistically significant at p < 0.05.
