We performed a histological study of the bone-implant interface on 2 human femurs implanted with a hydroxyapatite-coated self-locking stem for 2 years. Extensive bone formation with no intervening fibrous tissue was noted around the entire circumference of the 2 prostheses. The newly-formed bone had 2 morphotypes: an alveolar disposition with a continuous contact between bone and hydroxyapatite, and a digitiform one where distinct bony trabeculae were in contact with the ceramic coating or with the bone marrow. Partial or even total resorption of the hydroxyapatite coating was clearly identified, these areas showing bone in contact with the metal.
我们对2根植入羟基磷灰石涂层自锁柄2年的人股骨进行了骨-植入物界面的组织学研究。在2个假体的整个圆周周围均观察到广泛的骨形成，其间无纤维组织。新形成的骨有两种形态类型：一种是牙槽状排列，骨与羟基磷灰石之间连续接触；另一种是指状排列，明显的骨小梁与陶瓷涂层或骨髓接触。清楚地识别出羟基磷灰石涂层的部分甚至全部吸收，这些区域显示骨与金属接触。
