Advanced Polymers, Bioceramics, and Bioactive Metallic Compounds
Orthopedic biomaterials used in Chinese clinical settings encompass a wide range of synthetic and natural substances designed to interface directly with human bone tissue. Material selection depends heavily on load-bearing requirements, wear resistance parameters, and biological integration timelines across specific anatomical sites.
Mainstream material classifications utilized in reconstructive procedures include:
-
Polymeric Biomaterials: Ultra-high-molecular-weight polyethylene (UHMWPE) and polyetheretherketone (PEEK) dominate load-bearing joint bearings and spinal interbody fusion cages due to their excellent radiolucency and fatigue resistance.
-
Ceramics and Bioactive Glasses: Alumina, zirconia, and hydroxyapatite coatings provide optimal bio-inertness, minimal wear debris, and enhanced osseointegration for total hip replacements.
-
Advanced Metallic Alloys: Surgical titanium (Ti-6Al-4V) and cobalt-chromium-molybdenum alloys remain the gold standard for trauma plates, pedicle screws, and joint stems due to superior tensile strength.
-
Resorbable Biopolymers: Polylactic acid (PLA) and polyglycolic acid (PGA) composites are increasingly utilized for temporary fracture fixation, eliminating second-stage removal surgeries.
