| Summary: | Aim: Zinc is essential for normal bone growth and can promote bone regeneration. Processed human bone allograft treated with zinc shows improved bone formation activity. Various factors were tested for effects on zinc binding to bone allograft with the long-term goal of developing methods to enhance the bone formation activity and safety of bone allograft in orthopaedic applications. Methods: The amount of zinc bound to allograft was measured using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Fluorescent visualization of zinc bound to allograft was accomplished using Zinpyr-1. The potential anti-microbial property of zinc-treated allograft was measured by exposing allograft to Staphylococcus aureus. After washing, the exposed allograft was cultured in bacterial media to measure residual Staphylococcus aureus. Data were analyzed using standard parametric methods. Results: Rapid binding of zinc to bone allograft (1–15 min) was relatively insensitive to zinc concentration, incubation time, pH, or divalent cation competition. In contrast, zinc salt counter ions had significant effects, with zinc acetate producing more rapid zinc binding than zinc chloride or zinc picolinate. The ability of Staphylococcus aureus to contaminate bone allograft was also significantly reduced by prior zinc treatment. Conclusions: The study results provide guidelines for modifying the processing of bone allograft to enhance bone formation activity while also improving the resistance of the allograft to bacterial contamination. |
