Bone (n.) Old English ban "bone, tusk," from Proto-Germanic *bainam (source also of Old Frisian ben, Old Norse bein, Danish ben, German Bein). No cognates outside Germanic (the common PIE root is *os-; see osseous); the Norse, Dutch, and German cognates also mean "shank of the leg," and this is the main meaning in Modern German, but English never seems to have had this sense.
