High impact information on Acromion

• Our genetic studies show that Hoxa5 and Pax1 cooperate in the vertebral patterning of the cervicothoracic transition region and in acromion morphogenesis [1].
• The fourth and fifth sternebrae were also fused, and the acromion process of the scapula was missing in kkt mice [2].
• Here, we describe abnormalities of the ribs, neural arches, and acromion in Sp2H homozygous embryos, indicating a widespread dependence of lateral somite development on Pax3 function [3].
• We also found that cells situated close to the CAL attachment into the acromion exhibited elevated levels of G6PD and ALP activity, but intriguingly, also showed higher TRAP activity than neighboring cells distant from entheses [4].
• It became superficial by passing around the medial border of the muscle at an average of 8.7 cm (range, 6.3 to 10.9 cm) inferior to the posterolateral corner of the acromion [5].

Anatomical context of Acromion

• There was no contact between the supraspinatus tendon and the acromion when the shoulders were externally rotated in the coronal plane [6].
• The acromion and the coracoacromial ligaments removed during acromioplasty were fixed in 10% formalin, decalcified, embedded in paraffin, and cut into sections along the direction of the coracoacromial ligament [7].

Associations of Acromion with chemical compounds

• Twenty-eight of 33 acromions with coronal lateral downward sloping had impingement, and all 31 shoulders with medial encroachment had impingement [8].
• Three tantalum markers were inserted in the glenoid socket, two in the coracoid process and two in the acromion [9].

Gene context of Acromion

• The dynamics of expression of Hoxa5 and Pax1 in the pectoral girdle region suggest that both genes function in a complementary fashion during acromion formation [1].
• The shank of the cutter is rested against the posterior lip of the acromion, which acts as a fulcrum [10].
