Outcome | Odds ratio (with:without fusion) | 95% confidence interval |
---|---|---|
Girdlestone resection | 14.9 | 3.1–70.6 |
Infection | 6.9 | 2.3–20.3 |
Complications during index admission | 6 | 3.1–11.5 |
Revision | 4.9 | 1.7–14.3 |
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.
