For each trial, the posterolateral tip of the acromion, the inferior angle, and the edge of the spine of the scapula were digitized.
In clinic, assessment tools designed to measure the posterior displacement of the inferior angle of the scapula with reference to the posterior thoracic cage are needed.
For scapula position, triangulated location by Scapula Locator System of acromion, inferior angle, and root of the scapular spine; then measurement of scapula motion to determine symmetry, lag, or lead.
The Lateral Scapular Slide Test is a static test used in clinical settings to assess medio-lateral inferior angle displacement and scapular asymmetry at three different degrees of shoulder abduction.
The scapula is ossified from seven or more nuclei: one each for the body, the vertebral border and the inferior angle, and two each for the coracoid process and the acromion.
The apex created by two lines extending from the superior glenoid pole to the mid-point of the inferior angle and inferior glenoid pole determine the glenopolar angle Open image in new window Fig. 2 Medialization/lateralization displacement as measured on 3D CT reconstruction.
biceps brachii, m. triceps brachii (both halfway the upper arm), subscapular (just below the inferior angle of the scapula) and supra-iliacal (just above the iliac crest, in the midaxillary line), all on the non-dominant side of the body.
The subscapular was measured 1 cm below the inferior angle of the scapula.
The respective values are referred to as superior angle and inferior angle.
Chamber angle synechia was observed in the inferior angle [ 10– 10].
