Large calcification in the subscapularis tendon. These calcifications are hard to spot on X-ray, often best seen on a frontal image in external rotation. Very easy to detect on ultrasound. These are the images from a 53 year old man who works in the military. Pain at night and pain at rest. Sharp pain from about 80 degrees of abduction. Pain on sonopalpation of the calcification. He have had symptoms for nearly 2 years, tried all kinds of physiotherapy and treatments, including ESWT. We have tried SAB injection with corticosteroids and he was painfree for 4-5 months after that but then the symptoms gradually came back. So we decided to go for a ”Lavage-procedure” and flush out the calcification ?
