The physical examination, pain scoring, functional scale, disability scale, special tests, direct radiography findings and ultrasonographic imaging findings of the patients in this group before the treatment and 1 month after the treatment will be evaluated and will be recorded. Size of calcific deposits and Gartner classification will be evaluated on direct radiography. Size, shape, acoustic shadowing, power doppler activity of calcific deposits and other bursitis, tendinitis, ruptures, effusion in the shoulder will be evaluated on ultrasonographic imaging.

Patients in this group will be treated with ultrasound-guided lavage.

Patients in this group will be treated with ultrasound-guided subacromial bursa injection with corticosteroid and lidocaine.

After local anesthesia of subcutaneous tissue, lavage will be performed under the guidance of ultrasound using an 18-gauge needle with injectors filled with 4 ml of saline. The needle will be advanced to the center of the calcific deposit. The injector will be kept as parallel to the ground as possible. The plunger of the injector will be pushed with a gently pressure and then released. Calcific deposits are expected to be filled into the syringe along with saline. It is predicted that the clear saline will gradually turn white and become cloudy due to the incoming calcific deposits. When the color of the liquid becomes cloudy, the syringe will be removed without moving the needle, and a new syringe containing 4 ml saline will be placed in its place. Thus, the aspirated calcific deposits will not be reinjected. The same process will be repeated with a new saline filled syringe. After the procedure, 2 ml dexamethasone and 3 ml lidocaine will be injected in subacromial bursa.

The change in a participant's range of motion degree as measured by a goniometer (Passive Range of Motion and Active Range of Motion) from baseline to 1 month.

A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. A patient selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing "no pain" to '10' representing "worst possible pain"

The constant shoulder score is a validated scale, measuring the shoulder function. It is an objective measurement independent of the shoulder pain. It is a 100-points scale composed of a number of individual parameters. The minimum score is 0, the maximum score is 100 points. The higher the score, the higher the quality of the function.

Individual's ability to complete tasks, absorb forces, and severity of symptoms are measured by a 11 item Quick Dash questionnaire. At least 10 of the 11 items must be completed for a score to be calculated and the scores range from 0 (no disability) to 100 (most severe disability).

This score measures the disability of the shoulder in daily life, work, social life.0 points indicate maximum well-being, 100 points indicate maximum disability
