Wilson DJ, Scully WF, Rawlings JM. Evolving Role Of Ultrasound In Therapeutic Injections Of The Upper Extremity. Orthopedics. 2015 Nov;38(11): e1017-24.

Ultrasound provides the benefit of real-time, dynamic imaging without the radiation exposure of fluoroscopy, and ultrasound-guided injections can be performed in the office, as opposed to the operating room, which is frequently required when using fluoroscopy. Many locations for diagnostic and/or therapeutic injections in the upper extremities have improved accuracy and benefit with the use of ultrasound vs blind techniques, although a few have not been shown to have a significant difference in the literature. The educational and professional implications can be significant, but these potential benefits need to be carefully weighed against costs by each orthopedic practice.
