摘要：
A method of manufacturing an implant for use in a surgical procedure, a corresponding implant and the use thereof during the incorporation of a substance is presented. Specifically anodized and blasted titanium implant substrates are provided with a hydroxyapatite (HA) coating for incorporating for example a therapeutic agent. In particular, an anodizing procedure by an electrolytic process in an alkaline liquid is carried out. Moreover, blasting of the anodized titanium implant substrate is carried out by the presented method. The HA coating can be in the range of 1 to 5 μm, particularly in the range of 1 to 3 μm. A local delivery of the active pharmaceutical ingredient is achieved by the implant of the present invention. Moreover, the implant allows for the removal of the implant without damaging surrounding tissue or a bone. Moreover, the HA coating is provided to the substrate such that enhanced fixation as measured by pull-out force is achieved whilst having a relatively low removal torque. The HA coating and drug incorporation may be carried out sequentially but also co-precipitation approach can be used.
