Arthroscopic management of calcific tendinitis of the subscapularis tendon

Calcific tendinitis is a common disorder of the rotator cuff. Conservative treatment is frequently successful. For the patients remaining symptomatic after conservative treatment, excision of the calcium deposits offers a generally reliable pain relief. While calcific tendinitis is seen commonly affecting the supraspinatus tendon, it has been rarely reported involving the subscapularis tendon. We report on the clinical features, radiographic findings, arthroscopic treatment and results of one patient who presented a calcific tendonitis involving the subscapularis tendon of the left shoulder unresponsive to conservative treatment and associated subcoracoid stenosis and coracoid impingement.
