Early History
Vittorio Putti is considered as one of the
founders of orthopedic science and bone grafting
with his earliest papers dating back to 1912
Donati et al. (2007) Acta Orthopaedica 78(1)
19-25 .

Biomaterials
-Biocompatible materials -Biodegradable -Non-to
xic to the body
Amini A et al. 2012 Crit Rev Biomed Eng. 40 (5)
363-408.

Cellular Reconstruction
  • Bone grafting is a very effective repair
    mechanism but there are high rates of the cells
    rejecting the graft
  • Scaffolding combined with osteogenically active
    cells are very effective materials because it
    provides a great framework for the bone and
    promotes normal cellular growth

Nanoparticles
-No major surgery required in most
cases -Programmable -Can be used as the
scaffolding or in drug delivery to affected
site -Cost effective

Degradable and Non-degradable

-Dramatic changes in the past couple years -The
research into new materials such as nanoparticles
has increased significantly
