Sangiampong et al quoted that difference in the morphology of acromion and the presence of anterior acromial
spur and inferior acromioclavicular osteophytes decrease the subacromial space leading to impingement.
In that aforementioned case report, the patient had an acromial
fracture associated with supraspinatus tendon rupture.
Caption: Figure 1 Preoperative AP and axillary radiographs of the right shoulder demonstrating mild glenohumeral degenerative changes, acromial
enthesopathy, and hypertrophic ossification of the acromioclavicular joint.
Submitted to the Hawkins test, that verifies the conflict between the supraspinous muscle tendon and the coracoid acromial
ligament, the patient A.A., according to table no.
Associated injuries are among others acromial
fractures, glenohumeral dislocations, clavicle fractures and AC joint dislocations.
The absence of lateral and medial end of both clavicles (red arrow) with a tiny bone fragment was seen in the acromial
end of both clavicles (yellow arrow).
These landmarks included the tragus of the left ear, the left acromial
process and the left lateral malleolar process and the spinous process of 7th cervical vertebra.

In 1949, the first clinical application of a flap from the shoulder (charretera" or acromial
flap) was performed by Kazanjian and Converse8.
The height of normal subacromial space, from the coraco- acromial
arch to the HH, is only 1-1.5cm as seen on radiograph36 and is occupied by the supraspinatus tendon, subacromial bursa, LH of the biceps tendon, and the capsule of the shoulder joint.
The lateral or acromial
end is flattened from above downward.
The angle formed by the two processes of the scapula, the dorsally projected scapular process and the ventromedially projected acromial
process, is around 115 degrees (Fig.
The PHCA can further anastomose with the deltoid branch of thoracoacromial artery (ramus deltoideus arteriae thoracoacromialis) and the acromial
branches of suprascapular artery (rami acromiales
