La ligne verticale du plan du centre de cercle du trou de passage de tendon (31) du bloc de passage de tendon dorsal de doigt (30) et de la première partie dorsale de doigt (112) est une première ligne verticale (BE1). La ligne verticale du plan du centre de cercle du trou de passage de tendon (31) du bloc de passage de tendon dorsal de doigt (30) et de la seconde partie dorsale de doigt (113) est une seconde ligne verticale (AE2). Un point d'intersection (E) est présent entre la première ligne verticale (BE1) et la seconde ligne verticale (AE2). Un point tangent (F) est présent entre une ligne reliant le centre de cercle du trou de passage de tendon (31) du bloc de passage de tendon dorsal de doigt (30) sur la première partie dorsale de doigt (112) et le trou de passage de tendon (31) du bloc de passage de tendon dorsal de doigt (30) sur la seconde partie dorsale de doigt (113), et la surface d'arc. La longueur de la ligne reliant le point d'intersection (E) et le point tangent (F) est supérieure ou égale à la longueur de la ligne reliant le point d'intersection (E) et le point le plus élevé (C) de la surface d'arc.
