Material properties and progress in modification of hydrogel-based self-expandable poly(methyl methacrylate) bone...

Area of Science:

• Biomaterials Science
• Orthopedic Surgery
• Polymer Chemistry

Background:

• Traditional poly(methyl methacrylate) (PMMA) bone cements have limitations including high polymerization heat, poor bioactivity, and volumetric shrinkage.
• These drawbacks restrict the clinical application of PMMA bone cements in bone tissue repair.

Purpose of the Study:

• To review the material properties and modifications of self-expandable bone cement (SBC).
• To discuss the influence of functional monomers and fillers on SBC's biomechanical properties.
• To propose future research directions for SBC development.

Main Methods:

• Review of existing literature on self-expandable bone cement (SBC).
• Analysis of the impact of hydrophilic monomers on SBC properties.
• Evaluation of filler and antibiotic incorporation in SBC formulations.

Main Results:

• Self-expandable bone cement (SBC) exhibits enhanced bioactivity and tunable mechanical properties.
• SBC demonstrates excellent volumetric swelling due to water absorption in body fluids.
• SBC can incorporate antibiotics and fillers to prevent infection and achieve desired biomechanical performance.

Conclusions:

• Self-expandable bone cement (SBC) is a promising alternative to conventional PMMA bone cements.
• SBC's adjustable properties and bioactivity make it suitable for various orthopedic applications.
• Further research into SBC modifications can optimize its clinical utility.
