Impact of Prior Ipsilateral Arthrodesis on Subsequent Ankle and Subtalar Fusion Outcomes: A Propensity-Matched Cohort Study
Our analysis of the TriNetX Research Network database suggests that when the primary ankle or subtalar arthrodesis is successful, performing a subsequent adjacent fusion does not significantly increase the risk of nonunion compared with an isolated fusion. However, failed prior arthrodesis substantially increases nonunion risk, highlighting the importance of distinguishing between successful and failed prior procedures in clinical decision-making.
