BACKGROUND: The purpose of this study was to review 15 years of experience with ankle fusions, specifically addressing the underlying etiology of ankle pathology, incidence of nonunion, and associated predisposing conditions that can lead to nonunion.
METHODS: Seventy-eight ankle fusions, performed between 1975 and 1990, were reviewed for this study. The average follow-up was 4 years. Patients with nonunion were evaluated separately to look at the predisposing factors that may have lead to nonunion.

RESULTS: Factors associated with nonunion included fracture type, evidence of avascular necrosis, infection, major medical problems, and open injuries. Factors that were not associated with nonunion included age, past history of subtalar or triple arthrodesis, and technique.
