Blood Supply to the Humerus



- Discussion:
    - main blood supply to humeral head arises from anterolateral branch of anterior humeral circumflex artery;
    - this vessel passes laterally to long head of biceps & forms arcuate artery;
    - arcuate artery:
         - arises from ascending branch of anterior humeral circumflex artery as it penetrates bone;
         - it enters into humeral head in area of intertubicular groove & gives branches to lesser and greater tuberosities;
         - perfuses the entire epiphysis of the humeral head;
    - posterior circumflex artery supplies only a small area in posteroinferior aspect of the humeral head
