Erratum: Figure of the published manuscript titled: “Comment on the safety of the ultrasound-guided hydrodissection technique for carpal tunnel syndrome”

Dear Editors-in-Chief:

We would like to revise the submitted figure to our published article in the Journal of Ultrasound titled, “Comment on the safety of the ultrasound-guided hydrodissection technique for carpal tunnel syndrome” https://doi.org/10.1007/s40477-022-00664-5 [1]. We have noticed that the letter “A” was mistakenly placed on the left side, B-mode, in the uncolored part of Fig. 1C. We would like to submit a rectified version of this said figure. We believe this change reflects that the Journal of Ultrasound and its authors are diligent in reviewing all works, including those that have been published.

Fig. 1.

A Shows the sonoanatomy of a bifurcated median nerve (MN) (in yellow) in the carpal tunnel entrapped by the thickened fibrotic or scarring tissues (in green). B Shows the partially hydrodissected MNs surrounded by injectate (in blue) but the thickened fibrotic or scarring tissues are still trapping the MNs, so that the nerve still looks elliptical. C Shows a completely hydrodissected MN with both bundles looked rounded or oval and surrounded by injectate. FCR flexor carpi radialis tendon, FDS flexor digitorum superficialis tendon, FDP flexor digitorum profundus tendon, FPL flexor pollicis longus tendon, MN median nerve, RA superficial palmar branch of radial artery

Thank you for your consideration. I look forward to hearing from you.
