CHICAGO, Nov. 28—Minimally invasive, ultrasound-guided percutaneous therapy effectively treats tendonitis caused by calcium deposits in the shoulder, according to a study presented at the 93rd annual meeting of the Radiological Society of North America (RSNA).
"This is a quick, successful and inexpensive therapy for tendon calcifications," said Luca M. Sconfienza, MD, from the Department of Radiology at A.O. Ospedale Santa Corona in Pietra Ligure and the Department of Experimental Medicine at the University of Genova in Italy. "It provides significant and long-lasting reduction of symptoms."
Calcific tendonitis is a condition that causes the formation of small calcium deposits within the tendons of the rotator cuff in the shoulder. Ultrasound-guided percutaneous (through the skin) therapy represents an effective and inexpensive alternative to surgery that is less stressful for the patient, according to Sconfienza.
For the 10-minute procedure, the shoulder is anesthetized and, with ultrasound guidance, a radiologist injects a saline solution into the rotator cuff to wash the area and break up the calcium. A second needle is used to aspirate, or withdraw, the calcium residue. Recovery time is about an hour and calcifications that are completely treated do not ever return.
Sconfienza and colleagues used ultrasound-guided percutaneous therapy to treat 2,543 shoulders in 1,607 women and 938 men (mean age 42) with calcific tendonitis. All of the patients had shoulder pain that was unresponsive to previous medical treatment. One-year follow-up was reported for 2,018 of the patients in the study.
The results showed that in 71.7 percent of the patients, the calcification was fully aspirated in one treatment with a considerable reduction in pain and significant improvement to mobility of the affected limb. In 23.6 percent of patients, a second procedure was performed because of the presence of more than one calcification. In 3.8 percent of patients, the calcification had dissolved or moved before treatment could take place. In 0.9 percent of patients, no resolution of symptoms occurred because of the presence of a tendon tear.
Sconfienza said that theoretically, the procedure could be performed in any hospital or clinic that has ultrasound equipment with a superficial probe.
"As people age, many complain of pain in the shoulders. This pain is commonly caused by calcium build-up," Sconfienza said. "This procedure can allow them to feel better immediately with little cost."
