Ultrasound Guided Injections Evidence

The two most important aspects to consider when comparing ultrasound vs landmark guided injections are accuracy and efficacy.

For accuracy, the research literature shows ultrasound to be superior to landmark guided injections. This has important implications for precision diagnosis with injection of local anaesthetic.[1]

The research on efficacy is less conclusive and more higher quality studies are needed. The current evidence shows that ultrasound guided injections are superior to landmark guided injections for the glenohumeral joint, subacromial space, biceps tendon sheath, joints of the hand and wrist, knee, ankle, and foot.
