Scapula elevation

The possibilities that cryptic prostatic carcinoma may coexist with other diseases or that a high serum alkaline phosphatase activity possesses some residual activity at pH 5.0 tend to be negated by an analysis of these five patients. One female with carcinoma of the breast and osteolytic metastases of the femur, pelvis, and spine had an elevated serum acid phosphatase activity of 4.2 K.A. units, and a second female with an unknown primary but with osteolytic lesions of the ribs and scapula had an activity of 4.1 K.A. units. The serum alkaline phosphatase activities were 17.8 Bodansky units in the first case and 5.2 Bodansky units in the second case, both above 4.2 Bodansky units, the upper limit of normal values by this method.

Elevation Frontal A gliding movement of the scapula in an upward direction as in shrugging the shoulders. 

Depression Frontal Movement of the scapula downward in a direction reverse of elevation. 

The scapulothoracic joint movements are related to scapular motions. The motions are medial and lateral movements of the scapula on the thorax (abduction-adduction), elevation of the scapula, and upward and downward rotation of the scapula (tilt), all relative to the glenoid fossa. 

The scapulohumeral rhythm is a free-flowing and synchronous movement of the scapula and humerus. During abduction, the scapula rotates as the humerus elevates. For every 15 degrees of abduction, humeral elevation accounts for 10 degrees and scapular rotation accounts for 5 degrees. Dysfunction of humeral elevation or of scapular rotation can disturb this rhythm and interfere with shoulder function. Dysfunction of clavicular motion can also interfere with this rhythm.
