About

Calcific tendinitis of the shoulder, is a self-limiting disease characterized by the deposition of calcium phosphate crystals in the rotator cuff tendons. Patients will develop complications such as decreased range of motion of the shoulder joint, and thus reducing their quality of life. The most common site of occurrence is 1.5-2 cm away from the supraspinatus tendon insertion site on the greater tuberosity. The primary treatment for calcific tendinitis is conservative, such as non-steroidal anti-inflammatory analgesics for pain relieving, extracorporeal shock wave therapy, subacromial steroid injections, ultrasound-guided barbotage technique for aspirating and washing out calcific deposits. Ultrasound is being used in calcified tendinitis for evaluating its size, location, quality, and also using the color Doppler ultrasonography to evaluate its reactive inflammatory changes. However, the use of color Doppler ultrasonography in diagnosing and treating a shoulder pain with calcification is not being concluded yet. Therefore, the aim of this study is to evaluate the efficacy of color Doppler ultrasonography in calcified tendinitis.

Trial design

Primary purpose: Diagnostic

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

100 participants in 2 patient groups

With Doppler ultrasound

Experimental group

Description:

The physician will use Doppler function detection to check if calcifications are under active inflammation before ultrasound-guided injection.

Treatment:

Diagnostic Test: ultrasound Doppler function detection

Without Doppler ultrasound

Active Comparator group

Description:

The physician will only open the Doppler image in the non-calcified area for patient blinding before the ultrasound-guided injection.

Treatment:

Diagnostic Test: ultrasound Doppler function detection
