Calcific deposit needling in combination with extracorporeal shock wave therapy (ESWT): A proposed treatment for supraspinatus calcified tendinopathy.

BACKGROUND: Calcified tendinopathy of the rotator cuff is one of the most common conditions concerning the shoulder pathology. It is characterized by a reactive calcification that affects the tendons being part of the rotator cuff. The reported prevalence varies from 2.7% to 22%. Most of the patients can be treated effectively with non-operative measures such as anti-inflammatory drugs, subacromial injection of steroid, physiotherapy, extracorporeal shock wave therapy (ESWT) and needle aspiration irrigation. Results of a treatment combining some of these methods have not been reported.

OBJECTIVES: The purpose of this study is to present the radiological as well as the clinical results of our proposed protocol which combines drilling of the calcium deposits with xylocaine under ultrasound guidance, with a specific program of physiotherapy for 1 month without the use of NSAIDs.

METHODS: Sixty-six consecutive patients (68 shoulders) were treated for calcified tendinitis of supraspinatus, which was diagnosed clinically and radiologically, with needle drilling using xylocaine under ultrasound guidance. After the drilling the patient followed a physiotherapy protocol with ESWT which included five visits within a month. After the end of the physiotherapy, the patients were evaluated clinically and radiologically. The Visual Analogue Scale (VAS) for pain and the Disabilities of the Arm, Shoulder, and Hand (DASH) score were measured before and after the end of the therapy.

RESULTS: All the patients showed clinical improvement of the symptoms at the follow-up. The mean VAS score showed improvement from 8.1 to 3.3 whereas the mean DASH score was 27 and after the end of the therapy 5. Radiologically all but one calcific deposits were disappeared.

CONCLUSIONS: The ultrasound-guided drilling of the calcific deposit using xylocaine, in combination with physiotherapy using ESWT provides a reliable alternative treatment for the calcific tendinitis of the supraspinatus.
