Response to Musculus dorsoepitrochlearis and Development and Clinical Significance of the Musculus Dorsoepitrochlearis
Abstract
We agree with their idea that the terms for singular variations of the axillary region often do not correspond with their form, origin and insertion. We believe that better delineation could admittedly give a better account of this type of variation.
Reports of muscular variations from the 19th century each had slightly different descriptions but where often lumped together regardless of their development. Because of the fact that all of the variable muscular strips of the axilla have all their developmental origin in the phylogenetically ancient muscular material representing the dorsoepitrochlearis all variable muscular strips in the axilla despite their origin and insertion arose from this material.
After destruction of the original structure the muscular rudiments thus insert to nearby structures, which results in the variability of these muscular strips.We would suggest a unifying termsuch as axillary arch muscular rudiments without clinical symptoms or axillary arch muscular rudiments with clinical symptoms of nerve compression. Using this terminology, we woud be acknowledge the fact that the rudiments have a variable form, course and insertions but one common developmental origin.
