Abstract:
Ultrasound is a useful modality for guiding injections and other procedures in the extremities. Its portability and the ability to adjust the probe and needle in real time, as well as lack of radiation exposure make it preferable for many routine procedures. However, ultrasound is highly operator dependent and a firm understanding of regional anatomy is important, including neurovascular structures that are in close proximity during many of these procedures. Knowledge of the characteristic location and appearance of neurovascular structures in the extremities allows safe needle advancement and prevention of iatrogenic complications.
