Fig. 6 — Histological analyses of Al₂O₃@Ti pillars as well as Al₂O₃@HNR_es and Al₂O₃@ZNR_es patterned pillars implanted in S. aureus-infected marrow cavities of rat tibias for 3 days and 4 weeks: (a) Photographs and (b) the corresponding counts of S. aureus colonies formed by rolling the implanted pillars on blood agar plates and re-culturing for 24 h; (c) Micro-CT reconstructed images of the pillars implanted for 4 weeks and quantitation of (d) bone volume fraction (BV/TV %), (e) trabecular number (TB. N) and (f) trabecular thickness (TB. TH) of the peri-implant bone based on Micro-CT assay; (g) Van Gieson's staining images of the pillars implanted for 4 weeks and (h) corresponding bone-implant contacts. Data are presented as mean ± SD, n = 6, (*) p < 0.05 and (**) p < 0.01.
