Table IV.

Prevalence of nine combinations of FV  and AV  are displayed. Visualization of the nine combinations are shown in  Fig. 3A  for all patients, in  Fig. 4  for patients with cam-type FAI, in  Fig. 5  for patients with mixed-type FAI and in Fig. 3B for patients treated surgically

Aggravated combination (red) was present in groups A and I. FV = femoral version; AV = acetabular version.

aggravated = red moderate = yellow compensated = green Normal = green.
