The Effect of Doppler Ultrasound on Calcified Tendinitis

Condition(s) studied

Investigational drug(s) / intervention(s)

ultrasound Doppler function detection: Doppler function detection is an ultrasound technique that measures and visualizes blood flow within an object, such as vessels and soft tissue. It can be used to check for the inflammation status of calcifications by detecting blood flow around the calcified areas before performing an ultrasound-guided injection.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Need for a Second Ultrasound-Guided Injection — between three days to one week after the initial ultrasound-guided injection
  Whether a second ultrasound-guided injection is needed within a short period after the initial ultrasound-guided treatment, meaning whether significant improvement can be rapidly achieved after the first ultrasound-guided injection (defined as a reduction in pain index ≥50%).
