new implant for
bone reconstruction has recently debuted in the medical world.
Instead of rigid titanium plugging the holes in ones cranium, the new
implant is degradable, as well as made
of a synthetic bone-like material. The implant stimulates the
body to heal itself, at its custom fit allows it to disappear at the
same rate as the regrowing bone.Normally, the body will heal
itself – save for large injuries. So when a person happens to
puncture their skull (quite a large injury), medical help is
required. Instead of long-term doctor care, messy surgeries, and
other setbacks, the new transplant offers custom care. It replaces
the missing bone, until the body's own fissure closes up the hole.
implant is made to last as long as the body will need it – from a
few weeks to a year. In addition, instead of the solid implants to
date, this new implant is porous. At intervals of just hundred
micrometers, the openings allow for a lattice-type structure that the
patient's bone can grow into.
new implant was produced by the “Resobone” project of the Federal
Ministry for Education and Research. "Its precision fit
and perfect porous structure, combined with the new biomaterial,
promise a total bone reconstruction that was hitherto impossible to
achieve," says Dr. Ralf Smeets of the University Medical Center
of Aachean.Synthetic polylactide (PLA) and tricalium
phosphate (TCP) are the key ingredients to the custom implant. PLA is
employed in the implant's basic structure, and TCP ensures rigidity
and stimulates the patient's natural bone growth.
is a downside to the implant, however. It only be used in places in
the body where stress is not prevalent. So patients with
maxillary, and cranial bones, as well as holes less than 25
square centimeters, are eligible for “Resobone”
implants. The new implant surgery gives hope that
patients with severe bone injury can recover quicker, better, and
more comfortably. This new technology also steers away from the
controversial stem cell
subject. "No custom-fit, degradable implants
ever existed before now. We have achieved our project goal,"
said Simon Hoges, Project Manager at the Fraunhofer Institute for
