TRAUMATIC SUBLUXATION OF THE LONG HEAD OF THE BICEPS BRACHII: A Case Report.

LIEBERMAN, HERMAN S.
The Journal of Bone & Joint Surgery: April 1940
Case Report

The tendon of the long head of the biceps brachii is anchored within the intertubercular sulcus by the strong capsular attachments bridging the proximal portion of the sulcus and by the retinaculum farther distally. These tissues, due to repeated use, may become weakened and, under proper mechanical forces, may tear or stretch, thereby allowing the tendon to slip out of its groove.

Attrition need not, of necessity, be present, since sufficient mechanical forces acting in proper directions may also produce an acute rupture of the anchoring tissues and allow subluxation to take place.
