title: Gantzer's muscle-like variation inserted into the forearm flexor retinaculum.
abstract: A rare muscle variation belonging to the forearm flexor muscle group has been observed in three forearms out of nearly 200 Japanese cadavers. It arose from the well developed fascia of the superficial forearm flexor group, crossed the median nerve obliquely and posteriorly lying radial to that nerve, and was inserted into the flexor retinaculum. The muscle variations in the three cases were discussed according to the concept of "corrected" nerve-muscle specificity and conservative morphology. They were conclusively ascribable to the original antebrachial flexor group of Yamada. This seemed to indicate that the variations were related or identical to Gantzer's muscle, and that they showed a possible original or archaic pattern of the original antebrachial flexors.
