Calcifying tendinitis is a common condition of the shoulder. In many cases, arthroscopic reduction in the deposit is indicated. The localization of the deposit is sometimes challenging and time-consuming. Pre-operative ultrasound (US)-guided needle placement in the deposit and pre-operative US marking of the deposit at the skin with a ballpoint are described and recommended methods to alleviate the procedure without using ionizing radiation by fluoroscopy.
