Figure 3From: Proposal of a magnetic resonance technique for the evaluation of the calcaneofibular ligament minimizing false positive results Measure the angle of the CFL 3D sagittal plane. Trace the line in the sagittal plane, parallel to the horizontal flat surface, and another line was traced parallel to the plane of the ligament investigated. The angle between these lines was calculated using the tools of the MR device.Back to article page
