In this review we summarize recent guidelines of injection technique, as we presented at the practical workshops oft he «Medidays» congress at the University Hospital Zurich. Furthermore we discuss drugs, indications, complications, adverse reactions and contraindications. Lastly we discuss the role of ultrasound guided injections.
