    • A method of preparing an implant for bone in-growth comprising: providing a metal implant body, the metal implant body having a metal load bearing layer on an outer surface, the metal load bearing layer having a plurality of pores therein, the pores configured to promote bone in-growth into the load bearing layer; providing calcium sulfate hemi-hydrate; providing a diluent; mixing the calcium sulfate hemi-hydrate and the diluent to form a calcium sulfate paste; applying the calcium sulfate paste to the load bearing layer such that the calcium paste substantially impregnates at least a portion of the pores and forms an excess layer of the calcium sulfate paste on an outer surface of the load bearing layer; and wiping the calcium sulfate paste to remove the excess layer and thereby expose the outer surface of the load bearing layer while leaving the calcium sulfate paste impregnated in the pores.
    • 一种制备用于骨内生长的植入物的方法,包括:提供金属植入体,所述金属植入体在外表面上具有金属承载层,所述金属承载层在其中具有多个孔,所述孔构造成 促进骨内生长进入承载层; 提供硫酸钙半水合物; 提供稀释剂; 混合硫酸钙半水合物和稀释剂形成硫酸钙糊剂; 将硫酸钙浆料施加到承载层上,使得钙糊剂基本上浸渍至少一部分孔隙,并在载荷层的外表面上形成过量的硫酸钙浆料层; 并擦拭硫酸钙糊以除去过量的层,从而暴露承载层的外表面,同时留下浸渍在孔中的硫酸钙浆料。
