The finger bone of an elderly individual is going to take the longest to heal because the healing of a bone is dependent on the blood flow to that area. The elderly already have a weaker blood flow than healthy, young people, so the healing of their bones takes longer. On top of that, the finger gets less blood supply than the thigh bone, so it will take longer to heal than the thigh.
