title: [Role of computerized tomography in the evaluation of the stability of the glenohumeral articulation].
abstract: CT scans of the shoulder were performed on 30 normal subjects. The bony architecture of the glenohumeral joint and of the shoulder as described by definite angles and index was determined. Attention was primarily drawn upon the parameters often implicated in the mechanism of glenohumeral stability, namely: the glenoid antero-posterior tilt and the anteversion angle of the scapula. While the former is a static determinant, the latter is a dynamic determinant of joint stability. An inversely proportional relationship was found to exist between these two components of glenohumeral stability. It may be speculated that an high glenoid tilt, which is unstable, may be counterbalanced by a functional reduction in anteversion of the scapula, thus improving the joint stability.
