450-550Babylonian Talmud

  Sayings of the rabbis in the tractates of the Babylonian Talmud (Pesachim, Chullin, Horayot). Babylonian Talmud was written between about 450 - 550 in present-day Iraq (formerly Babylonia). The rabbis discuss the presence of ligamentum capitis femoris (LCF) in different animals, its location, role, distal attachment area, and the possibility of damage.  See our commentary at the link:   450-550BabylonianTalmud [Rus].
