Titanium Hydroxilapatite Coated Metacarpo-Phalangeal and Interphalangeal Implant

Abstract

At present, the artificial replacement of the metacarpo-phalangeal or interphalangeal joints is still an unsolved problem. Clinical experiences have releaved the limits of cemented prostheses (Flatt’s prosthesis, Schultz’s prosthesis and Biomeric) and also of articular spacers (Swanson’s implant, Niebauer’s prosthesis, Swanson’s-gromets implant). So we have planned an uncemented implant, a titanium Dac Blu hydroxilapatite coated prosthesis.

In this paper, we explain the features of the prosthesis, giving an example of its clinical use. The Dac Blu hydroxilapatite coating improves the biostability and the biocompatibility of the implant to the host bone. To confirm this fact, we report histological data on the interface between Dac Blu hydroxilapatite screws and human bone. Besides, our aim is to extend the casuistry and the follow-up.
