It is important to know a truer incidence of the need for subtalar and midfoot fusions, following an isolated ankle fusion, in order to better inform our patients of the likelihood of needing further surgery in the future. It is also important to understand whether pre-existing radiological arthrosis is likely to lead to the need for a fusion in the future and also how important the alignment of the ankle joint, after a fusion, may influence that.
The aim of the study is to review the patients' notes and radiology who have had a previous isolated ankle fusion and then to see whether they subsequently required further surgery.
