Before assessing a novel muscle in the hand, please be very careful

“…5) In the discussion the authors state that the existence of an accessory AADM muscle has been previously described [4]. According to this consideration and to the description in the case report section, Antonopoulos et al [1] accept the described unique muscle as a hypothenar variation; this is in contrast to their previous assessment for an extra wrist muscle in the abstract. However, if they accepted an insertion to the fifth metacarpal, as they present in the start of discussion and conclusion, thus an extra wrist muscle which might involve the wrist function should be accepted.…”

“…Before assessing a novel muscle in the hand, please be very careful I read with interest the article of Antonopoulos et al [1] on the study of a variant hypothenar muscle: "Aberrant accessory abductor digiti minimi manus muscle: a rare anatomical variation", which the authors accept as unique.…”

“…Moreover, all of the reported examples are different variants of the ADMM, not a cases of extra wrist muscles. 2) Antonopoulos et al [1] reported that the presented accessory ADMM originated from the tendons of the flexor digitorum superficialis (FDS). Firstly, I would like to point out not so representative dissection and fixation of the upper extremity.…”
