Planning

X-ray of the shoulder that should include:

  • Frontal with and without external rotation of the shoulder
  • Scapular outlet view

Evaluation

File:Subacromial space on outlet view X-ray.jpg
Supraspinatus outlet view X-ray, showing subacromial space measurement, and an acromial spur (above the arrow).
  • 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. For severity grading, see X-ray of osteoarthritis of the shoulder
  • Presence of any calcifications in the supraspinatus tendon, which indicates a differential diagnosis of calcific tendonitis.

Report

  • Either normal subacromial space, or a decrease thereof, with measurement of the space.
  • Presence or absence of an acromial spur.
