Inflammation of a tendon triggered by calcium deposits, or calcific tendinitis, can effectively be treated with a simple and cost effective percutaneous method according to a recent study conducted by researchers from the Hospital de Basurto in Bilbao, Spain.
“We started treating calcific tendinitis as the result of the request of several members of our hospital staff that were suffering from this condition,” said Jose Luis del Cura, MD, lead author of the study. “The results we obtained in these few cases encouraged us to offer this treatment to our patients. Later, in collaboration with the rheumatology department of our hospital, we conducted a study to evaluate the efficacy of the procedure,” said Dr. del Cura.
The study consisted of 67 shoulders that were treated with sonographically guided percutaneous needle lavage i.e. injections of lydocaine or saline. According to the study, one year after treatment, 91% of shoulders had considerably or completely improved. Of the 67 shoulders treated, 64% had perfect motion and the calcifications had resolved completely or nearly completely in 89% of the patients.
“A significant amount of the patients (about half of them) experienced a transitory limited recurrence about two months after the treatment, which we found surprising,” said Dr. del Cura. “When the recurrence did occur, the symptoms were different; milder and predominately at night, lasted several weeks and finally disappeared, usually without sequels. We hypothesized that this may have been the result of reparative changes inside the tendon,” he said.
