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. 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. 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.
本研究的目的是回顾15年踝关节融合术的经验，特别探讨踝关节病变的潜在病因、骨不连发生率以及可能导致骨不连的相关诱发因素。本研究回顾了1975年至1990年间进行的78例踝关节融合术。平均随访时间为4年。对骨不连患者进行单独评估，以查看可能导致骨不连的诱发因素。与骨不连相关的因素包括骨折类型、缺血性坏死证据、感染、重大医疗问题和开放性损伤。与骨不连无关的因素包括年龄、距下关节或三关节融合术既往史以及手术技术。
