To conclude:
this chapter was a walk in the dark, exploring how fractures were,
are and possibly will be healed, hereby taking also a couple of sideroads. We tried
to make clear once again that materials properties and design constraints are inti-
mately linked to achieve a successful end product. A next big leap in hard tissue
implantology seems to be imminent but breakthroughs of the size brought about by
Charnley or Ilizarov are not seen yet.

G.A. Ilizarov
In total hip arthroplasty, the bell name is Prof. Charnley (see Chap.
2
). Another
monument of orthopedic surgery is Gavril Abramovich Ilizarov.
Fiddler on the roof, a village in tsarist Russia in 1905 (musical from 1964 based
on a topic of Joseph Stein). It could well have been a scenery of the village Dagestan
near Vitebsk (Russian Caucasus), where on June 15, 1921 Ilizarov was born as the
oldest of eight children of a poor family. He could only start his school curriculum
