Ultrasound-guided injections in rheumatology: actual knowledge on efficacy and procedures.

Ultrasound allows one to detect easily joint involvement. In addition to its primary use as a diagnostic tool, ultrasound is increasingly used by rheumatologists to guide musculoskeletal interventions. The correct position of the needle in the target area offers the chance to improve efficacy of the local procedure. Knowledge of anatomy and probe positioning as well as the ability to coordinate probe and needle are necessary when injecting patients with ultrasound guidance. Lack of training and of clear guidelines on their practice is demonstrated by recent surveys and by the high variability of the literature results evaluating practice and outcome of ultrasound-guided injections. This chapter deals with actual knowledge and practical suggestions for the indications and procedures of ultrasound guidance in rheumatology daily practice.
