Customised hip resurfacing arthroplasty implant

The purpose of CustomHip is to create an innovative metal hip arthroplasty implant (customized to the patient's needs) with a ceramic coating in order to avoid all the negative effects and disadvantages of friction between metal surfaces (metal on metal), while retaining all the advantages of the surface arthroplasty method, i.e., minimal bone removal of the femoral head.

Objectives of the project are:

A. The design and production of a resurfacing arthroplasty implant The project aims at the development of an innovative surface arthroplasty implant consisting of a metal skeleton bearing a ceramic coating.
B. The development of an implant personalization software The project aims at the development of an automated software for customized design and manufacturing of the resurfacing arthroplasty implant.
C. Dissemination The aim of the dissemination and publicity activities is the promotion of the project and its potential benefits to stakeholders from industry, as well as to academic and research communities outside the consortium.

Impact:

The orthopedic inventor Dr. I. Vlachos in collaboration with Akmelogi SMPC initiated the research project for the development of a new, World Patented, implant for Hip Arthroplasty, based on the connection of academic research (required condition) focusing on the great need of the medical world and the world market to solve with a simple, minimally invasive and viable way the hip osteoarthritis problem. The main expected results from the implementation of the project can be summarized as follows:
  • Development of a new implant for hip resurfacing arthroplasty that will tackle effectively the problem of lesions of the hip joint avoiding total hip arthroplasty (total replacement of the hip joint after removal of the diseased femur head).
  • Designing the new implant is proven to solve fracture problems of the femoral neck and aseptic detachment of the implant, while the successful coating of metal surfaces with a strong adhesive ceramic coating of low surface roughness will give an answer to the problem of metal on metal wear.
  • The new implant will therefore provide a solution to a large number of patients worldwide (1 million operations per year) through a simple operation, providing them with complete restoration of their motor abilities.
  • The competitiveness and outreach of Akmelogi and MIRTEC10 in the international markets will be enhanced from the exploitation of the results of the research project.
  • Entrepreneurship and innovation will be supported in new products in the the healthcare and materials sectors.
  • Creation and maintenance of specialized jobs (3 equivalents of annual employment).
  • Full exploitation of dissemination and publicity tools (publications, exhibitions, workshops, social networks, participation in innovation transmission networks) to increase the impact of the research project.
