Impact of Prior Ipsilateral Arthrodesis on Subsequent Ankle and Subtalar Fusion Outcomes: A Propensity-Matched Cohort Study.

ABSTRACT:

Background

Although prior ankle or subtalar arthrodesis is thought to affect outcomes at adjacent joints, previous studies have not distinguished between successful and failed prior fusions. This study examines whether prior successful vs failed ipsilateral arthrodesis influences nonunion risk in subsequent ankle or subtalar fusion. The primary objective of this study is to examine nonunion rates after subtalar and ankle arthrodesis in patients with and without prior ipsilateral arthrodesis, and vice versa.

Methods

A retrospective study using the TriNetX Research Network compared nonunion rates in patients who underwent subtalar (ST) arthrodesis with (ankle-ST) or without (ST-only) prior ankle arthrodesis. Patients were stratified by whether the prior arthrodesis was success
