Origin of The Long Head of Triceps

Anatomical anomalies of triceps are not common. During the course of a cadaveric dissection in CAHID a rare bilateral variation of the attachment of the long head of triceps was found in a 62 year old female cadaver. The long head of triceps was attached to the infraglenoid tubercle and the posteroinferior aspect of the glenohumeral joint capsule, as well as by a fibrous extension between 3 to 4 cm long to the superior part of the lateral border of the scapula.
