Prosthetics by personal measure
Samara scientists have learned how to "grow" joint prostheses on a 3D printer
Samara scientists have mastered the technology of 3D printing of joint prostheses selected individually for each patient, Sergey Chaplygin, head of the Department of project Management, Production and Engineering of the Institute of Innovative Development of Samara State Medical University, told reporters.
"This prosthetics technique has been patented by us. Now we have completed preclinical tests on laboratory animals and now we are starting clinical trials. Such titanium prostheses were created using 3D printing technology and can be used in patients with arthrosis (dystrophic joint disease caused by damage to cartilage tissue) or if the joint is lost as a result of injury," Chaplygin said.
Prostheses are a joint development of the Medical University and Samara University named after Korolev. The novelty of the development lies in the fact that the prostheses are created personified for each person, taking into account the individual characteristics of the patient. The clinical requirements for the prosthesis are supplied to the scientists of Samara University by doctors. Specialists use special 3D powders to create the desired shape of the joint. In order to "grow" a prosthesis in a 3D printer, it takes about a day, about the same time it takes to model it.
The technology allows you to get different properties on different parts of the joint. For example, on the part that will be in contact with the bone, it is possible to obtain porosity, so that later tissues germinate there and reliable fixation of the prosthesis is ensured. The articular surface, on the contrary, turns out to be very smooth to reduce friction. In the future, scientists plan to create large joints, for example, knee joints or pelvic elements.
After the completion of clinical trials, scientists intend to commercialize the project. To date , in There are no analogues of such prostheses in Russia. It is assumed that the cost of a personalized prosthesis will not exceed 50 thousand rubles.
Another implantation project developed at Samara Medical University is dental implants made of metal rubber. Such a development can be used in difficult cases when patients have, for example, osteoporosis. A dental implant based on metal rubber has biocompatibility, hypoallergenic and "shock-absorbing" properties, that is, it has little mobility, like a human tooth. Now specialists are looking for an investor who could engage in serial production of the development.
