Ultrasound Guided Injections
The use of ultrasound to evaluate musculoskeletal structures was first reported in 1958. Since then, its use has grown exponentially, particularly in the office setting.
Ultrasound enables physicians to reliably visualize soft-tissue structures including muscle bellies, tendons, ligaments, arteries, and nerves, as well as identify any pathologic changes within these structures. The use of ultrasound has several advantages, including the relatively lower cost compared to other imaging methods and the absence of ionizing radiation. It is a repeatable, noninvasive imaging modality that is capable of providing real-time dynamic tissue assessment. In addition, ultrasound can be used to quickly compare the affected and contralateral sides when necessary.
