Wood as Possible Renewable Material for Bone Implants-Literature Review

Area of Science:

• Biomaterials Science
• Orthopedic Surgery
• Materials Engineering

Background:

• Millions suffer from bone fractures and defects annually, necessitating effective treatments.
• Current treatments rely on metal implants and autologous bone grafts, with ongoing research for better alternatives.
• Wood has emerged as a potential sustainable and biocompatible biomaterial for bone repair applications.

Purpose of the Study:

• To explore the potential of wood as a biomaterial for bone implants.
• To review existing research on wood-based materials for bone defect reconstruction and fracture fixation.
• To assess the biocompatibility and osteoconductivity of wood implants.

Main Methods:

• Literature review of studies investigating wood and wood-derived materials for bone repair.
• Analysis of various wood preparation techniques, including pre-treatments, carbonization, and cellulose extraction.
• Examination of composite materials combining wood-derived scaffolds with other elements like hydroxyapatite.

Main Results:

• Wood implants demonstrate good biocompatibility and osteoconductivity.
• The porous structure of wood facilitates bone integration and regeneration.
• Modified wood materials, such as carbonized wood and cellulose scaffolds, show potential for enhanced properties.

Conclusions:

• Wood represents a promising, sustainable biomaterial for bone implants.
• Further research into wood processing and composite development can optimize its clinical application.
• Wood's inherent properties offer a viable alternative for bone defect reconstruction and fracture fixation.
