Summary

Shoulder impingement syndrome involves higher subacromial pressures compared to controls. These pressures increase with humeral abduction in impingement patients, particularly antero-laterally under the acromion.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Sports Medicine

Background:

  • Shoulder impingement syndrome is a common cause of shoulder pain.
  • Subacromial space pressure is a potential indicator of shoulder pathology.

Purpose of the Study:

  • To measure subacromial space pressures in patients with shoulder impingement syndrome and controls.
  • To investigate the effect of humeral abduction on subacromial pressures.

Main Methods:

  • Pressures were recorded during open surgery under general anesthesia.
  • A 2-mm-thick piezo-electric pressure transducer was used.
  • Measurements were taken in 14 patients with impingement syndrome (Neer's stage II) and 8 controls with acromioclavicular dislocation.

Main Results:

  • Subacromial pressures were significantly higher in the impingement group compared to the control group.
  • The highest pressures in both groups were recorded antero-laterally under the acromion.
  • In impingement patients, pressures increased significantly with increasing humeral abduction.

Conclusions:

  • Elevated subacromial pressures are associated with shoulder impingement syndrome.
  • Humeral abduction exacerbates subacromial pressure elevation in impingement.
  • Antero-lateral acromial region is critical for pressure monitoring in shoulder impingement.
