Comparison of Focused Shock Waves or Ultrasound-Guided Needling and Lavage in Patients With Calcifying Tendinopathy of the Shoulder
Study Details
Study Description
Brief Summary
Currently, the only study comparing the long-term results of these procedures (two years) is that of Kim.(24) This study is the first randomized, blinded clinical trial comparing ultrasound-guided percutaneous lavage ( UPL) for rotator cuff calcific tendinopathy with subacromial injection vs. Shock (1000 impulses/0.36mJ/mm2), obtaining clinical improvement and reabsorption of calcification in both groups. In this study, greater effectiveness was observed in terms of pain improvement and functional recovery in these patients in the short term than in those undergoing UPL: The results of this study were obtained through radiographic evaluation (AP X-ray of the shoulder) before and after intervention and clinical evaluation in both groups using the scales of the American Society of Shoulder and Elbow Surgeons (ASES), the Simple Shoulder Test (SST) and the Visual Analogue Scale (VAS).
Our future work may add many interesting data to the comparative study of these two techniques, since it would provide new results, overcoming the limitations of the only similar study in the literature today.
On the one hand, the radiological selection of patients will be carried out with shoulder X-rays and a shoulder ultrasound performed by two expert musculoskeletal radiologists from this center and validated by interobserver correlation. This will allow a detailed selection of patients according to the characteristics and phases of the calcification that they present. Sonographically, calcifications are classified into three types (according to Garner's 1993 classification): type I, II and III. As we have previously mentioned, calcific tendinopathy is a self-limited disease and we know that calcifications in phase III or in the resorption phase tend to resolve spontaneously. The control ultrasound that will be performed on the patients will also be performed by the same expert musculoskeletal radiologists who have performed the interobserver correlation study.
Secondly , we are going to define a maximum number as well as the exact protocol for carrying out the Eco - guided Puncture Lavage technique .
Another contribution of our work is that we will carry out an evaluation of the differences between both techniques up to two years post-treatment, which will allow us to know the long-term evolution of the results.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: shockwave therapy The calcification will be located by ultrasound and the energy will be applied in the precise place. 3 sessions will be carried out as follows: 1, 2, 3 weeks This procedure will be carried out by a single experienced Physical and Rehabilitation medical doctor |
Procedure: shockwave therapy, barbotage and infiltration
ultrasound guided interventions
|
| Experimental: Ultrasound-Guided Barbotage The calcification will be located by ultrasound. By injecting serum at high pressure, it is intended to wash away the calcification. A subacromial inyection will be associated with this procedure. A maximum of 3 Ultrasound-Guided Barbotage will be performed with an interval of 6 weeks between each puncture. This procedure will be performed by two experienced radiologists |
Procedure: shockwave therapy, barbotage and infiltration
ultrasound guided interventions
|
| Experimental: us guided subacromial injections An US guided subacromial injection (1 cc of corticostheroid ) and anesthetic (2 cc of mepivacaine) will be performed. The periodicity will be one infiltration every 8-10 weeks, being able to carry out a maximum of 3 per year. |
Procedure: shockwave therapy, barbotage and infiltration
