Ultrasound guided injections in rheumatology.

Ultrasonography has gained popularity among rheumatologists especially in Europe as a bedside imaging method for diagnosing soft tissue lesions such as synovitis in joints, bursae and tendons. In addition to diagnosing the lesion ultrasound can be used to monitor needle position during the injection procedure. The aim of this paper is to describe injection techniques guided by ultrasound into the joints, bursae or tendon sheaths. We point out that the value of ultrasound in rheumatology is not only diagnostic but also therapeutic.
