Ultrasound Guidance of Injections
Ultrasound guidance of injections allows a greater degree of accuracy and permits a greater variety of injections to be performed, compared to palpation guidance. The technique can also improve safety, in that neurovascular structures and articular cartilage can be visualized and avoided. Its successful implementation depends on a firm knowledge of the relevant anatomy and adherence to proper procedures. By no means should it be considered facile. This chapter reviews the current literature regarding injection accuracy, discusses issues of safety and technique, and describes a variety of injections of varying difficulty. It should be considered an adjunct to a more formal training program.
