Elbow Joint Sonoanatomy and Ultrasound-Guided Elbow Joint Injection

The elbow is a common site for sports related injuries of the upper extremity. Ultrasonography (US) is a noninvasive imaging modality that offers several distinct advantages over its cross sectional counterparts. These include real time dynamic evaluation, direct patient feedback, ability to guide therapeutic interventions, and among many others. This chapter will review the normal anatomy of the elbow and its sonographic appearance, the approach to US imaging, the commonly encountered disease pathologies, and several fundamental therapeutic interventions for the elbow.
