[Periarthropathia humeroscapularis].

Degeneration of the rotator cuff causes the painful periarthritis humeroscapularis. Especially the supraspinatus tendon is afflicted. 90-95% of patients with acute affection of supraspinatus tendon get free from symptoms with conservative treatment. Impingement syndrome of the rotator cuff will also get free from symptoms with conservative treatment. When the symptoms persist in spite of treatment, the operative enlargement of the acromiocoracoidal passage is indicated. Periarticular soft tissue calcification often becomes painful during spontaneous absorption of calcium deposits. Conservative treatment is in the foreground.
