Background

National Metal and Materials Technology Center (MTEC), National Science and Technology Development Agency (NSTDA) and Orthopaedic surgery, Musculoskeletal Oncology, the Royal College of Orthopaedic Surgeons of Thailand with Piya Kiatisevi, M.D, Lerdsin hospital, share the same opinion that the imported prosthesis for bone tumour patients is too expensive, cannot be reimbursed by National Health Security Office (NHSO) and has many usability issues.

Therefore, the initiative for research and development of the humeral prosthesis produced in Thailand with reasonable price and, at the same time, addresses usability issues was proposed. The proximal humeral prosthesis was chosen to be the first tumour prosthesis to be developed.

 

Objective

We aim to develop the proximal humeral prosthesis that complies with the international standard at reasonable price for bone tumour patients. A reasonable priced implant provides an alternative treatment to amputation for low income patients. Furthermore, the developed implant also provides business opportunity for medical device industry in Thailand.

Conclusion

The proximal humeral protheses are tested in 10 patients at the leading hospitals under supervision of the Ethics Committee1 of each hospital. The treatment outcomes show satisfactory functional results and low complication rates. Although the movement of affected arm is not as good as the unaffected arm, the patient feels more confident after the treatment.

Current status

Cosmo Meditec Ltd. has signed the licensing agreement for production and commercialization of “Modular proximal humeral prosthesis” On May 1, 2017.

Outlook

MTEC researchers and orthopaedic surgeons are interested in the development of other prosthetic body parts such as hip prosthesis.
