AB  - AIMS: The aim of this study was to examine the real time in vivo kinematics of
      the hip in patients with cam-type femoroacetabular impingement (FAI). PATIENTS
      AND METHODS: A total of 50 patients (83 hips) underwent 4D dynamic CT scanning of
      the hip, producing real time osseous models of the pelvis and femur being moved
      through flexion, adduction, and internal rotation. The location and size of the
      cam deformity and its relationship to the angle of flexion of the hip and pelvic 
      tilt, and the position of impingement were recorded. RESULTS: In these patients
      with cam-type FAI, there was significant correlation between the alpha angle and 
      flexion to the point of impingement (mean 41.36 degrees ; 14.32 degrees to 57.95 
      degrees ) (R = -0.5815 and p = < 0.001). Patients with a large cam deformity
      (alpha angle > 78 degrees ) had significantly less flexion to the point of
      impingement (mean 36.30 degrees ; 14.32 degrees to 55.18 degrees ) than patients 
      with a small cam deformity (alpha angle 60 degrees to 78 degrees ) (mean 45.34
      degrees ; 27.25 degrees to 57.95 degrees ) (p = < 0.001). CONCLUSION: This study 
      has shown that cam-type impingement can occur early in flexion (40 degrees ),
      particularly in patients with large anterior deformities. These patients risk
      chondrolabral damage during routine activities such as walking, and going up
      stairs. These findings offer important insights into the cause of the symptoms,
      the mechanisms of screening and the forms of treatment available for these
      patients. Cite this article: Bone Joint J 2017;99-B(4 Supple B):41-8.
