Acromion Morphology in Coronal and Sagittal Plane; Correlation with Rotator Cuff Syndrome

From June, 2004 to December, 2005, 71 cases were surgically proven to beimpingement syndrome, and the anterior acromial hooking angle, the lateral acromial hooking angle(AAHA and LAHA) and the acromial hooking index (AHI: the sum of the AAHA and LAHA) were com-pared to 16 control cases. At the same period, 55 cases were surgically proven to be partial or full thick-ness rotator cuff tear, and age, gender and twelve anatomic parameters, including the acromial type, theacromial angle, the anterior covering, the acromial slope, the AAHA, the lateral acromial angle, the acro-mial torsional angle, the lateral acromial angulation, the LAHA, the lateral covering, the acromiohumeraldistance and the AHI were assessed.
