  • Analysis of factors affecting mechanical properties (synthesis, processing, sterilization).
  • Evaluation of degradation mechanisms and influencing factors (chemical composition, mechanical properties).

Main Results:

  • Mechanical properties and degradation rates are critical for resorbable implant performance.
  • Implant degradation involves fragmentation, strength loss, and molecular weight decrease.
  • Resorbable polymers show promise for trauma surgery devices, with ongoing needs for optimization.

Conclusions:

  • Resorbable polymers are suitable for various medical implants, offering benefits over metal alternatives.
  • Material composition and mechanical properties significantly influence degradation and tissue response.
  • Three-dimensional porous scaffolds hold potential for future tissue-engineered implants.
