Assessment of Hip Translation In Vivo in Patients With Femoracetabular Impingement Syndrome Using 3‐Dimensional Computed Tomography

Figures

• 

  Fig 1. Illustration demonstrating 3-dimensional computed tomographic right-sided hip models at neutral (left) and FABER (right) positions. (FABER, flexion, abduction, and the external rotation.)

• 

  Fig 2. A global view of the right-sided femoral head superimposed with the color code representing the amount of bony protrusion (red) or indentation (blue) and an atlas view of a planar projection of the globe for calculation of cam deformity height and volume.

• 

  Fig 3. Image demonstrating the 3D-3D registration technique for calculation of translation of a right-sided femoral head center from the neutral position (green dot) to the FABER position (red dot). (FABER, flexion, abduction, and the external rotation.)

  Fig 4. Diagram indicating the number of patients meeting inclusion criteria from the study, and the number of patients meeting the inclusion criteria that were included in the final analysis. (CT, computed tomography; FAIS, femoroacetabular impingement syndrome.)
