MUSCULOSKELETAL ULTRASOUND-
a diagnostic AND therapeutic toolKelly Williams, DO

OBJECTIVES
WHY ultrasound is advantageous as a diagnostic tool
WHAT types of pathologies USD can and cannot be useful in diagnosing
WHAT types of injections USD is used to guide
WHAT types of injections USD is NOT useful for
2
INTRO
Linear Transducer (15‐6MHz)Higher ResolutionLower Depth
Dinnes et al‐USD (95%) and MRI (89%) highly sensitive for full‐thickness tears, but USD (67%) more sensitive than MRI (44%) for partial thickness tears
Lenza et al (Cochrane)‐MRI, MRA, USD all sensitive for full tears, USD possibly less for partial
Diagnostic: improved resolution, but limited by depth and limited to extra‐articular pathologies, and learning curve
Therapeutic: improved safety, particularly useful for guiding medications into otherwise non‐visualizablepathology (nerve, tendon), developing use in interventional spine care
