Accuracy of Anterior Shoulder Injections Without Image Guidance: A Prospective Controlled Study

This study shows that an anterior-superior approach shoulder injection technique performed by a shoulder specialist without image guidance has a high precision rate. However, in physicians with no experience in shoulder surgery, as well as in some pathologies such as adhesive capsulitis, the accuracy of the procedure decreases significantly and thus, in these cases, the use of some type of image guidance during the procedure may be recommended to achieve greater precision.
