Injury
Tearing of the labrum can occur from either acute trauma or repetitive shoulder motion such as in the sports of swimming and baseball. Acute trauma may be from dislocation of the shoulder, falling on an outstretched arm, direct blows to the shoulder, and other accidents of the sort. Tears are classified as either superior or inferior in regards to where the tear is in the glenoid cavity. A SLAP (superior labrum, anterior to posterior) lesion is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. Because a SLAP lesion involves the biceps, pain and weakness may also be felt when performing elbow flexion with resistance.

Famous quotes containing the word injury:
“A great proportion of architectural ornaments are literally hollow, and a September gale would strip them off, like borrowed plumes, without injury to the substantials.... What if an equal ado were made about the ornaments of style in literature, and the architects of our bibles spent as much time about their cornices as the architects of our churches do? So are made the belles-lettres and the beaux-arts and their professors.”
—Henry David Thoreau (1817–1862)
“Men have come to speak of the revelation as somewhat long ago given and done, as if God were dead. The injury to faith throttles the preacher; and the goodliest of institutions becomes an uncertain and inarticulate voice.”
—Ralph Waldo Emerson (1803–1882)
“This is ... a trait no other nation seems to possess in quite the same degree that we do—namely, a feeling of almost childish injury and resentment unless the world as a whole recognizes how innocent we are of anything but the most generous and harmless intentions.”
—Eleanor Roosevelt (1884–1962)
