A new bone graft substitute made by conversion of the calcium carbonate exoskeleton of reef-building sea coral into hydroxyapatite has recently become clinically available. The normal radiographic appearance of two forms of this material is described. In the immediate postoperative period, the exoskeletal architecture of these implants is readily appreciated. With graft incorporation over the ensuing months, their intrinsic structure is gradually lost in association with poor marginal definition. Evolving radiographic findings reflect the biocompatible nature of these implants, which provides the potential for ingrowth of native bone with preservation of the coralline scaffold, resulting in enhanced biomechanical properties.
一种通过将造礁海珊瑚的碳酸钙外骨骼转化为羟基磷灰石制成的新型骨移植替代物最近已投入临床使用。本文描述了这种材料两种形式的正常放射学表现。在术后即刻，这些植入物的外骨骼结构很容易辨认。在随后的几个月中，随着移植物的融合，它们的固有结构逐渐消失，边缘清晰度变差。不断演变的放射学表现反映了这些植入物的生物相容性，这种生物相容性为天然骨向内生长并保留珊瑚支架提供了可能，从而增强了生物力学性能。
