A hydroxyapatite-coated hip hemi-prosthesis was retrieved from a 98-year-old osteoporotic woman 12 weeks after implantation. Histologic analysis revealed bone and fibrous tissue almost evenly distributed around the surface of the implant circumference. Quantitative histologic analysis showed that 48% of the hydroxyapatite surface was covered by bone. Fibrous tissue covered 30% of the prosthetic surface, and 20% of the surface had no tissue coverage. Scanning electron microscopy showed direct contact without any clear boundary between the newly formed bone and the hydroxyapatite ceramic.
从一名98岁骨质疏松女性体内取出一枚植入12周后的羟基磷灰石涂层半髋关节假体。组织学分析显示，骨组织和纤维组织在植入物圆周表面几乎均匀分布。定量组织学分析表明，48%的羟基磷灰石表面被骨组织覆盖。纤维组织覆盖了30%的假体表面，20%的表面没有组织覆盖。扫描电子显微镜显示新形成的骨组织与羟基磷灰石陶瓷之间直接接触，没有任何明显界限。
