Summary

Posterior glenoid osteophytes in throwing athletes often indicate internal impingement and rotator cuff tears. Surgical treatment yielded mixed results, with only 55% returning to their previous throwing level.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Shoulder Surgery

Background:

  • Posterior glenoid osteophytes are associated with posterior shoulder pain in throwing athletes.
  • These osteophytes may indicate internal impingement and lead to rotator cuff and labral tears.

Purpose of the Study:

  • To evaluate the long-term outcomes of surgical treatment for posterior glenoid osteophytes in throwing athletes.
  • To determine the relationship between osteophyte size and return to sport.

Main Methods:

  • A long-term follow-up study of 22 patients treated for posterior glenoid osteophytes.
  • Arthroscopic evaluation and surgical debridement of rotator cuff and labral tears.
  • Arthroscopic removal of posterior glenoid osteophytes in 11 patients.

Main Results:

  • 55% of patients (10 of 18) returned to their premorbid level of throwing, remaining asymptomatic.
  • A trend towards poorer outcomes was observed with osteophytes larger than 100 mm2.
  • One patient experienced recurrence of the exostosis 8 years post-surgery.

Conclusions:

  • Posterior glenoid osteophytes are a marker for internal impingement in throwing athletes.
  • Surgical management can lead to good outcomes, but return to high-level throwing is not guaranteed.
  • Osteophyte size may influence the success of surgical intervention.
