Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether the combination of removal of the calcification in calcific tendinitis of the shoulder (supraspinatus and/or infraspinatus tendon) by aspiration with a needle and syringe (barbotage) and a corticosteroid injection is more effective than corticosteroid or sham injection alone.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Barbotage is a sonographically guided percutaneous needle aspiration and lavage of the calcium deposit in calcific tendinitis of the shoulder. Persisting pain in cacific tendinitis is considered to be a consequence of increased tendon volume or changed tendon texture in the area of the calcification which leads to secondary impingement and inflammation. Consequently, removal of the deposit should be a causal treatment measure.

Scientific evidence for the efficacy of the barbotage procedure in patients with persistent symptoms from calcific tendinitis is still limited. The cyclic often self-limiting course of the disease, and an anticipated placebo effect, questions about the method's efficacy can only be answered by high-quality randomized studies. In this trial the investigators want to randomize a cohort of patients to (1) Ultrasound guided needling, lavage and subacromial steroid injection, (2) Ultrasound guided subacromial steroid injection or (3) Ultrasound guided lidocain injection (sham). The investigators want to follow the patients over two years with repeated testing with a set of validated outcome measures together with radiologic re-examinations. The investigators want to find out whether the active treatments (1, 2) are more effective than the sham treatment and whether there are differences in outcome between the two active treatments. To increase the generalizability of the investigators' results, the investigators want to perform the study as a multi-centre study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Barbotage

Ultrasound guided needling, lavage and steroid/lidocain injection (20 mg Triamcinolon/9 ml Lidocain 1%) Ultrasound guided lidocain injection (10 ml Lidocain 1%, sham group) and home exercises

Group Type EXPERIMENTAL

Barbotage

Intervention Type PROCEDURE

A 18-gauge needle connected to a 5 ml syringe with 4 ml of saline solution will be used to puncture the calcification with freehand technique and under constant sonographic monitoring. With the tip of the needle placed in the center of the deposit, the calcification will be flushed. Finally, a new 21-gauge needle will be introduced into the subacromial-subdeltoid bursa and 9 ml of 1% Lidocain hydrochlorid and 1 ml (20 mg) of Triamcinolon will be injected into the subacromial-subdeltoid bursa. All patients will be instructed by a physioteherapist in home exercises.

Corticosteroid injection

Ultrasound guided steroid/lidocain injection (20 mg Triamcinolon/9 ml Lidocain 1%) and home exercises

Group Type ACTIVE_COMPARATOR

Corticosteroid injection

Intervention Type PROCEDURE

The tip of the 18-gauge needle will be placed in the soft parts outside of the rotator cuff and movements mimicking the lavage procedure will be performed. A lavage procedure usually takes 5 minutes and the same period of time will have to be used for the mimicking maneuver. Finally, a new 21-gauge needle will be introduced into the subacromial-subdeltoid bursa and 9 ml of 1% Lidocain hydrochlorid and 1 ml (20 mg) of Triamcinolon will be injected into the subacromial-subdeltoid bursa. All patients will be instructed by a physioteherapist in home exercises.

Lidocain injection (sham)

Ultrasound guided lidocain injection (10 ml Lidocain 1%, sham group) and home exercises

Group Type SHAM_COMPARATOR

Lidocain injection (sham)

Intervention Type PROCEDURE

The tip of the 18-gauge needle will be placed in the soft parts outside of the rotator cuff and movements mimicking the lavage procedure will be performed. A lavage procedure usually takes 5 minutes and the same period of time will have to be used for the mimicking maneuver. Finally, a new 21-gauge needle will be introduced into the subacromial-subdeltoid bursa and 10 ml of 1% Lidocain hydrochlorid will be injected into the subacromial-subdeltoid bursa. All patients will be instructed by a physioteherapist in home exercises.
