Figures & Tables

Radiographic measurements: (A) Anterior Impingement angle (AIa) and Posterior Impingement angle (PIa) in normal group, (B) AIa and Pia in EBI group, (C) sigmoid notch coverage angle (SNC) in normal group.

Manual flexion-extension range of motion (fROM) and radiographic measurement correlations between (A) f lexion and Anterior Impingement angle AIa, (B) extension deficit and Posterior Impingement angle (Pia).
