In the present study, two different pore sized scaffolds of the Mg alloy LAE442, coated with magnesium fluoride, were compared. The scaffolds had interconnecting pores of either 400 (p400) or 500\u2009\u00b5m (p500). \u00df-TCP served as control. Ten scaffolds per time group (6, 12, 24, 36\u2009weeks) were implanted in the trochanter major of rabbits. Histological analyses, \u00b5CT scans, and SEM\/EDX were performed. The scaffolds showed slow volume decreases (week 36 p400: 9.9%; p500: 7.5%), which were accompanied by uncritical gas releases. In contrast, \u00df-TCP showed accelerated resorption (78.5%) and significantly more new bone inside (18.19\u2009\u00b1\u20091.47\u2009mm\n                    <jats:sup>3<\/jats:sup>\n                    ). Bone fragments grew into p400 (0.17\u2009\u00b1\u20090.19\u2009mm\n                    <jats:sup>3<\/jats:sup>\n                    ) and p500 (0.36\u2009\u00b1\u20090.26\u2009mm\n                    <jats:sup>3<\/jats:sup>\n                    ), reaching the centrally located pores within p500 more frequently. In particular, p400 displayed a more uneven and progressively larger surface area (week 36 p400: 253.22\u2009\u00b1\u200919.44; p500: 219.19\u2009\u00b1\u20094.76\u2009mm\n                    <jats:sup>2<\/jats:sup>\n                    ). A better osseointegration of p500 was indicated by significantly more trabecular contacts and a 200\u2009\u00b5m wide bone matrix being in the process of mineralization and in permanent contact with the scaffold. The number of macrophages and foreign body giant cells were at an acceptable level concerning resorbable biomaterials. In terms of ingrown bone and integrative properties, LAE442 scaffolds could not achieve the results of \u00df-TCP. In this long-term study, p500 appears to be a biocompatible and more osteoconductive pore size for the Mg alloy LAE442.\n
