Morrison C, Brown B, Lin D, et al. Analgesia and anesthesia using the pericapsular nerve group block in hip surgery and hip fracture: a scoping review. Reg Anesth Pain Med 2021;46:169–175. doi:10.1136/rapm-2020-101826

The authors wish to direct the readers’ attention to the retraction of two case reports cited in this review that been retracted due to academic misconduct.1

The first retracted article ‘Clinical experiences of the pericapsular nerve group (PENG) block for hip surgery’ was consistent with other articles described in the scoping review and thus the conclusion remains unchanged.2

The second retracted article ‘Pericapsular nerve group (PENG) block is effective for dislocation of the hip joint’ was the only article describing the PENG block as a sole anesthetic technique.3 Thus on page three the paragraph subtitled ‘Anesthesia outcomes’ and on page four the tabled results subtitled ‘PENG block as a sole anesthetic technique for analgesia’ should be disregarded.
