Spam (food) Spam (stylized SPAM) is a brand of canned precooked meat made by Hormel Foods Corporation.

Subacromial (SA) impingement is defined as the mechanical compression of subacromial structures between the coraco-acromial arch and the humerus during active elevation of the arm above shoulder height.
The round head of the humerus fits into a socket on your shoulder blade just under a ledge of bone on your outer shoulder called the acromion. The sequence of the scapulohumeral rhythm varies depending upon whether you take your arms out to the side and overhead, an action called abduction, or forward and overhead, which is termed flexion.
