一种新的骨移植替代品，通过将造礁海洋珊瑚的碳酸钙外骨骼转化为羟基磷灰石制成，最近已在临床上可用。描述了这种材料的两种形式的正常射线照相外观。在术后即刻，这些植入物的外骨骼结构很容易理解。在随后的几个月里，随着移植物的掺入，它们的内在结构逐渐丧失，边缘清晰度差。不断发展的影像学结果反映了这些植入物的生物相容性，这为天然骨的长入提供了可能性，同时保留了珊瑚支架，从而增强了生物力学性能。
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.
