Bone grafting is frequently performed in orthopedic surgeries. Artificial bone is a common grafting material. We have developed an absorbable material for bone regeneration with a unique structure: unidirectional porous β-tricalcium phosphate (Affinos;Kuraray Co., Ltd., Tokyo, Japan). The most distinctive feature of this material is the ease with which blood can rapidly reach its depths by capillary action due to the unidirectional porous structure. It is also characterized by the presence of micropores, which are known to be beneficial for osteoconductivity both on the surface and inside the material. Favorable artificial bone absorption and regeneration with natural bone were observed in cases of clinical bone graft applications in the spine, extremities, benign bone tumor, trauma, and donor sites. Affinos is useful as a novel absorbable material for bone regeneration in various orthopedic surgeries.
骨移植在骨科手术中经常进行。人工骨是一种常见的移植材料。我们开发了一种具有独特结构的可吸收骨再生材料：单向多孔β-磷酸三钙（Affinos；日本东京可乐丽株式会社）。这种材料最显著的特点是，由于其单向多孔结构，血液可通过毛细作用迅速到达其深处。它的另一个特点是存在微孔，已知微孔对材料表面和内部的骨传导性都有益。在脊柱、四肢、良性骨肿瘤、创伤和供体部位的临床骨移植应用案例中，观察到了人工骨与天然骨良好的吸收和再生情况。Affinos作为一种新型可吸收材料，在各种骨科手术中对骨再生很有用。
