Spam (food) Spam (stylized SPAM) is a brand of canned precooked meat made by Hormel Foods Corporation. It was first introduced in 1937 and gained popularity worldwide after its use during World War II. By 2003, Spam was sold in 41 countries on six continents and trademarked in over 100 countries (except in Middle East and North Africa).
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 shoulder joint has a very loose joint capsule known as the articular capsule of the humerus and this can sometimes allow the shoulder to dislocate. The long head of the biceps brachii muscle travels inside the capsule from its attachment to the supraglenoid tubercle of the scapula.
