The strength characteristics of the interface between bone and a bone/porous metal composite were analyzed. The metal was 316L stainless steel. The average tensile strength of bone spicules ingrown to the porous metal was 46.5 MPa. This compares to a control bone sample strength of 89.7 MPa. The difference could be due to bone location and bone immaturity. The overall intefacial tensile strength (9.59 MPa) is necessarily lower since the spicules cover only a fraction of the interfacial cross-section. The overall interfacial strength had a wide range of scatter (s = +/- 4.11 MPa). This was probably due to inherent variations in bone strength with location. A population of samples using porous metal with average pore diameters under 100 micrometers exhibited measurably lower tensile strengths.
分析了骨与骨/多孔金属复合材料界面的强度特性。金属为316L不锈钢。长入多孔金属的骨小梁的平均拉伸强度为46.5MPa。相比之下，对照骨样本的强度为89.7MPa。这种差异可能是由于骨的位置和骨未成熟所致。由于骨小梁仅覆盖界面横截面的一部分，整体界面拉伸强度（9.59MPa）必然较低。整体界面强度有很大的离散范围（s = +/- 4.11MPa）。这可能是由于骨强度随位置的固有变化所致。使用平均孔径小于100微米的多孔金属的一组样本表现出明显较低的拉伸强度。
