Polymers, Ceramics, Composite Scaffolds, and Metallic Biomaterials
Orthopedic biomaterials encompass a diverse range of natural and synthetic substances engineered to interact safely with human biological systems. Selecting the appropriate biomaterial depends heavily on the mechanical load, anatomical location, and desired rate of biological integration required for the clinical application.
The primary material classes utilized in modern orthopedic surgery include:
-
Ceramic Biomaterials: Hydroxyapatite (HA), tricalcium phosphate (TCP), and bioactive glass offer exceptional biocompatibility and osteoconductive properties, making them ideal for bone defect fillers and implant surface coatings.
-
Polymeric Materials: High-performance polymers such as Polyetheretherketone (PEEK) and bio-absorbable polymers like Polylactic Acid (PLA) provide tailored mechanical strength for spinal interbody cages and suture anchors.
-
Metallic Biomaterials: Titanium alloys, cobalt-chromium, and porous tantalum remain the gold standard for load-bearing joint replacements due to their high fatigue strength and mechanical durability.
