Planning

X-ray of the shoulder that should include:

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

Evaluation

Supraspinatus outlet view X-ray, showing subacromial space measurement, and an acromial spur.
  • 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
  • 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.
