Porous ceramics of hydroxyapatite was fabricated utilizing the crystal growth of thin icecolumns parallel to one another in gelatin gel containing hydroxyapatite nanoparticles. Theobtained ceramics possessed unidirectional pore channels with a porosity of around 75% andshowed compressive strength of up to 13.1 MPa. As control materials, porous hydroxyapatiteceramics with a directionless pore structure were also fabricated by isotropic freezing and comparedwith the unidirectional samples regarding compressive strength and tissue reaction in vivo.Although the porosity and pore size distribution were similar, the compressive strength and newbone formation ability of the unidirectional samples were significantly greater than those of therandom structured porous ceramics
