Fig. 1From: A novel approach for joint line restoration in revision total ankle arthroplasty based on the three-dimensional registration of the contralateral tibia and fibulaDefinition of segments for ankle joint line approximation. Three anatomical segments (blue) were defined for registration and depicted from left to right. Distal (left model): defined at 98% of the tibia length and the corresponding fibula. Middle (center model): Defined from 75–90% of the tibia length and corresponding fibula. Proximal (right model): The segment was defined from 0 to 75% of the tibia length and the corresponding fibula. Coordinate system depicted: z-axis (green arrow), x-axis (blue arrow), y-axis: (red arrow facing the reader)Back to article page
