Cytocompatibility assays with primary human osteoblast-like cells. Cells were cultured for three days with the medium only (Medium), the titanium control (CTRL), the modified K-wire (Porous), the gentamicin-loaded K-wires (Genta), and the toxic control (Positive); n = 6 samples per group. The positive/toxic-group showed a significant reduction in metabolic activity (A) (*p ≤ 0.0280 compared to CTRL, Porous, Genta) and alkaline phosphatase activity (B) (#p ≤ 0.0335 compared to Medium, CTRL, Porous, Genta). Statistics: all groups compared to the positive control; n = 6.
