Component design and functionalization of absorbable bone wax: from bench to bedside

Area of Science:

• Biomaterials Science
• Orthopedic Surgery
• Regenerative Medicine

Background:

• Current bone wax lacks absorbability and multifunctional properties, limiting clinical application.
• Component design is critical for achieving desired absorbability and functionalization in bone wax.
• There is an urgent clinical need for safe and efficient absorbable bone wax in orthopedic procedures.

Purpose of the Study:

• To comprehensively review the development of component design and functionalization of absorbable bone wax.
• To analyze the relationship between component design and absorbability in different categories of bone wax.
• To elucidate the link between bone wax components and functional outcomes such as hemostasis, osteogenesis, and antibacterial activity.

Main Methods:

• Classification of absorbable bone wax into alkylene oxide copolymer-based, polyester-based, and bioceramic cement-based categories.
• Analysis of component-correlated absorbability within each category.
• Review of studies correlating component design with functional outcomes (hemostasis, osteogenesis, antibacterial activity).

Main Results:

• Absorbability is strongly correlated with the specific components used in alkylene oxide copolymer, polyester, and bioceramic cement-based bone waxes.
• Component selection influences key functional outcomes including hemostasis, osteogenesis, and antibacterial properties.
• Commercial absorbable bone waxes present specific clinical advantages and limitations that are summarized.

Conclusions:

• Future absorbable bone wax development should focus on controllable degradation and multifunctional integration.
• Standardized evaluation frameworks are needed to bridge translational gaps in absorbable bone wax research.
• The evolution of bone wax aims to transform it from a passive agent into an intelligent, tissue-regenerative platform for precision orthopedics.
