钛涂层317L接骨板螺钉骨界面的光镜观察

Light Microscopic Observation of Bone Interface of Titanium-coated 317L Plate Screw

报告了钛涂层317L接骨板螺钉骨界面光镜观察结果．两种螺钉植入后均形成骨整合骨界面，但钛涂层317L接骨板螺钉骨界面新骨形成较早，炎性反应较轻，金属与骨结合更紧密，而未涂层317L接骨板螺钉骨界面金属与骨仅为贴合关系．表明钛涂层317L接骨板螺钉骨界面及组织生物相容性优于317L接骨板螺钉．

The observational results of bone interface of titanium-coated 317L plate screw and 317L plate screw under light microscope are reported in the present paper. Osseointegration was formed in botb kinds of screws after implanting. In the titanium-coated 317L plate screw group,the inflammatory reaction was slighter,the new bone formed earlier in the interface and the bone was combined with the metal tightly,whereas in the uncoated 317L plate screw group,the relationship between th, bone and metal was only a state of contact. These indicate that the bone interface and tissue compatibility of titanium-coate4 317L plate screw may be better than that of the 317L plate screw.
