Planning
X-ray of the shoulder that should include:
- Frontal with and without external rotation of the shoulder
- Scapular outlet view
Evaluation
- Measurement of the subacromial space. This is normally in shoulder radiographs is 9–10 mm; this space is significantly greater in men, with a slight reduction with age.[1] In middle age, a subacromial space less than 6 mm is pathological.[1]
- Presence of any acromial spur
Also look for common differential diagnoses or worsening factors of shoulder impingement:
- Osteoarthritis. See severity grading at X-ray of osteoarthritis of the shoulder
- Presence of any calcifications in the supraspinatus tendon, which indicates a differential diagnosis of calcific tendonitis.
Calcifications in the supraspinatus tendon.
Report
- Either normal subacromial space, or a decrease thereof, with measurement of the space.
- Presence or absence of an acromial spur.
