Abstract
There was no evidence of osteonecrosis in the specimens analysed. The hydroxyapatite-coating was present to a variable degree on the specimens with good evidence of bony ongrowth under the CoChrome cap. Ongrowth was examined in five different zones with the greatest seen in the middle of the stem. Direct contact between newly formed bone and the hydroxyapatite layer was observed on light and back-scattered electron microscopy. Histomorphometric analysis quantified the mean bone-implant contact ranging from 11.1 to 33.6% between the specimens. DECLARATIONS
