The terminology of “bioresorbable polymers” covers several polymer families. The polylactides and polyglycolides are the most used in surgery. Under normal physiological conditions, they are hydrolysed in nontoxic degraded products (lactic and/or glycolic acids) easily metabolized and eliminated by the body under CO2 and H2O.
All these polymers are well tolerated and do not present any toxicity for the organism. Numerous tests on animals but also clinical studies show this with polyesters on lactic and glycolic acids based.
Beta Tricalcium Phosphates (βTCP) are osteoconductive materials that help to restore the bone tissue when in contact with the bone.
Bioglasses are silica based materials, containing calcium and phosphates, which favour the osteointegration.
NATURAL PEEK / CARBON FIBER REINFORCED (CFR) PEEK
PEEK is a semi crystalline aromatic polymer, biocompatible and used in permanent implants. It can be charged with carbon fibres in order to improve its mechanical characteristics.
The main advantages are:
- Excellent mechanical performance
- High wear resistance
- Possibility of repeated sterilizations with all current techniques without affecting the performance
- Total or partial x-ray transparency
- Elastic modulus closed to human bone
Polymethylmethacrylate mainly used for the manufacturing of centralizers or spacers for cemented hip joints
VBM / NEWS
