Synthetic biodegradable polymers offer promising alternatives for bone replacement, providing tailored properties and supporting tissue ingrowth. This review highlights four key polymer classes for orthopaedic applications.

Area of Science:

  • Biomaterials Science
  • Polymer Chemistry
  • Orthopaedic Engineering

Background:

  • Bone defects often require grafts or non-degradable implants, which have limitations.
  • Synthetic biodegradable polymers present tunable mechanical and degradation profiles.
  • These polymers can be fabricated into porous scaffolds to promote cell infiltration and tissue regeneration.

Purpose of the Study:

  • To review synthetic biodegradable polymers for bone replacement applications.
  • To discuss polymers with properties suitable for orthopaedic tissue engineering.
  • To identify promising polymer classes for future development.

Main Methods:

  • Literature review of synthetic biodegradable polymers for bone regeneration.
  • Analysis of polymer properties: mechanical, degradative, and cellular interactions.
Keywords:
Non-programmatic

  • Focus on four specific polymer classes: poly alpha-hydroxy esters, polyphosphazenes, polyanhydrides, and polypropylene fumarate.

    • Main Results:

    • Synthetic polymers can be designed with specific mechanical strength and degradation rates.
    • Processing into porous scaffolds enhances tissue ingrowth.
    • Functionalization of polymers can actively influence cellular behavior and tissue formation.

    Conclusions:

    • Synthetic biodegradable polymers are viable alternatives to traditional bone grafting materials.
    • Poly alpha-hydroxy esters, polyphosphazenes, polyanhydrides, and polypropylene fumarate show significant potential for orthopaedic applications.
    • Further research into functionalized polymers could lead to advanced bone regeneration strategies.
