Scientists from the Kurchatov Institute and the Petrovsky Russian Research Center for Surgery have developed biodegradable implants (cages) used for fusion of the vertebrae – today, non-degradable implants are used in medicine, forever in the outcome and theoretically repeated cases of different origin.
A dorsal implant for a biodegradable material (polylactide) construct, which is placed during surgery and replaces a destroyed intervertebral disc, prevents fusion of adjacent vertebrae damaged due to disease or injury. In the end, the vertebrae are connected by this cage, which over time is replaced by bone tissue.
Polylactide cages, consisting of a host of bone density and a porous zone, completely decompose It was at the postoperative stage, the first tests were successful, with the latest biodegradable implants. In the near future, tests of the first samples of polylactide implantation on animals will begin.
This is unknown, this laboratory of polymaterials of the “Kurchatov Institute” is currently actively and actively engaged in polylactide and various copolymers with various compositions, and they themselves have extensive experience in the synthesis of this material and the “tuning” of its properties.
Evidence from laboratory studies that polylactidades fully replaces its non-degradable alogs in the manufacture of various and not very different only.
