Conversion of Symptomatic Ankle Arthrodesis Nonunion to Total Ankle Arthroplasty Using Patient-specific Instrumentation and Computer-assisted Surgery Guides: A Case Report
Abstract:A 69-year-old woman developed a painful ankle fusion nonunion and underwent conversion to a total ankle replacement. Preoperative navigation was performed using a computed tomography scan and computer modeling system to develop patient-specific instrumentation and surgery guides. We described the navigation process of a fixed-bearing, computer-guided total ankle implant when performing an ankle arthrodesis takedown due to symptomatic nonunion and converting to a total ankle arthroplasty. The use of this techno… Show more
