Case contributed by Dr Maulik S Patel

Presentation

History of fall from bike two months back. Injury to the left upper chest. History of left upper posterior rib fracture. Complaining of pain in the left shoulder. Referred to check rotator cuff integrity.

Patient Data

Age: 65 years
Gender: Male
Ultrasound

Intact and normal echo pattern of the rotator cuff.

No bursal effusion.

No glenohumeral effusion.

Acromion shows cortical breach, fragmentation.

Ultrasound findings favored acromial fracture over less likely os acromiale. Shoulder axial view radiograph was ordered to differentiate them.

X-ray

Fracture line through the acromion process of the scapula.

If corticated margins are noted on both sided of lucency, it favors os acromiale.

Case Discussion

Findings of normal and intact cuff with acromial fracture.
