Musculoskeletal ultrasound has evolved throughout the last decade. This procedure allows accurate corticosteroid injections guidance. Precision is much higher than the infiltration performed blindly or under fluoro- scopy. The purpose of our approach is to describe our tech- nique in ultrasound-guided infiltration of the shoulder with an overview of the results.

123 cases of ultrasound-guided infiltration of the shoulder were selected in our institution from July 2011 to June 2012. They are divided into sub-acromial sub-deltoid bursitis, biceps tenosynovitis, acromioclavicular osteoarthritis, adhesive capsulitis and cal- cific tendinosis lavage and aspiration.

The infiltra- tion technique and the sonographic appearance in each con- dition are described. The rate of improvement is estimated between 70 and 80%.

The ultrasound-guided infiltration provides an accurate and minimally invasive thera- peutic option before any surgery. Recovery and socio-profes- sional integration prove to be optimal and fast.
