After thorough review and careful consideration, it has come to our notice that certain inaccuracies need to be rectified for the sake of clarity and mutual understanding.

The errors identified are as follows:

(1) In the Introduction, a previous cadaveric study is cited as reporting a percentage of phrenic nerve staining; however, the specific percentage value is not explicitly stated.

(2) In the Discussion, the cadaveric study by Laumonerie et al. appears to be referenced with an incorrect citation number.

(3) In the INTRODUCTION section, the reference citations in the sentence “~after shoulder surgery, which can delay discharge after outpatient shoulder surgery [5,9,11].” were incorrect.

To rectify the errors, we propose the following amendments:

(1) In the Introduction, the sentence, ‘According to a subsequent cadaveric percent of ultrasound-guided anterior suprascapular nerve blocks exhibit methylene blue dye diffusion to the phrenic nerve [13]’ did not mention the specific percentage of phrenic nerve staining. The sentence should be corrected to “According to a subsequent cadaveric study, 20 percent of ultrasound-guided anterior suprascapular nerve blocks exhibit methylene blue dye diffusion to the phrenic nerve [13].”

(2) In the Discussion, the cadaveric study by Laumonerie et al. was cited with ‘This is anatomically plausible because the distance between the plexus and the suprascapular nerve in the supraclavicular fossa was 8 mm in cadavers and 9 mm in volunteers [11].’ should be corrected to “This is anatomically plausible because the distance between the plexus and the suprascapular nerve in the supraclavicular fossa was 8 mm in cadavers and 9 mm in volunteers [13]”.

(3) In the INTRODUCTION section, the sentence should have reference '10' cited instead of '11'. So it should be“~after shoulder surgery, which can delay discharge after outpatient shoulder surgery [5,9,10].”

We apologize for any inconvenience these errors may have caused and assure you that they were unintentional.
