We read with interest the paper by Hall and Buchbinder,¹ which discussed the importance of accurate needle placement guided by imaging techniques in the therapeutic response to local corticosteroid injection (LCI) for musculoskeletal (MSK) conditions.

Certainly, as the authors state,¹ more studies providing evidence of short and long term benefit and cost effectiveness of imaging guided LCI versus blinded injection are needed. However, we would like to make some comments on a number of important points.

Firstly, Hall and Buchbinder¹ include in radiological guidance different imaging techniques such as radiography, computed tomography (CT), magnetic resonance imaging, and ultrasonography (US). We would like to point out that MSK US has considerable advantages over other imaging modalities …
