Analysis of the Multiwalled Carbon Nanotubes Reinforced Polymethyl Methacrylate Bone Cement’s Characteristics and In Vitro Bioactivity to Prolong Its Functionality in Orthopedic Application

Polymethyl methacrylate (PMMA) bone cement is being used to fill voids that are created due vertebral compression fractures. It also a grouting medium in orthopedic joint replacement surgeries as they possess fast primary fixation the bone. Considering properties and vitro bioactivity of essential for cemented hip knee surgeries. In this study, commercial Simplex P (SPBC) modified with carboxyl- (-COOH-) functionalized multiwalled carbon nanotubes (MWCNTs) overcome high polymerization temperature, volumetric shrinkage, surface wettability, bioactivity. A geometric dilution method incorporate MWCNTs PMMA powder, which unequal proportions. The PMMA/MWCNT nanocomposite different concentrations reinforcements, such 0.1, 0.3, 0.5, 0.7 weight percentages, prepared investigation. was observed had beneficial impact on (PMMA-BC) by enhancing its setting time (2.94%↑) wettability (23.58%↑). Also, diminished temperature (29%↓) shrinkage (40.9%↓) an optimum concentration wt. %. validated simulated body fluid (SBF) through development secondary apatite. concluded synthesized nanocomposites found have enhanced compared PMMA-BC.
