[Ultrasound-targeted joint puncture in rheumatology]

Joint punctures not only have a long tradition but are also an essential component in the diagnostic differentiation of various joint diseases. In addition, therapeutic injections are an essential component of an individual targeted treatment strategy in a disease-modifying antirheumatic drug (DMARD)-based treat-to-target concept. This article aims to convey to the reader the ultrasound-targeted joint puncture techniques in text and with many video clips that can be downloaded. This article therefore steps away from the conventional two-dimensional demonstration of anatomy-oriented puncture techniques and elucidates the diagnostic and therapeutic potency of ultrasound-targeted techniques in the daily routine. Furthermore, special importance is given to a sterile working technique, puncture material and synovial analysis.
