      • Modular orthopedic implants based on intelligent materials
      • Applications of Shape Memory Alloys, especially Nitinol, to the biomedical field have been successful because of their advantages over conventional implantable alloys, enhancing both the possibility and the execution of less invasive surgeries.
      • Important properties of Nitinol: biocompatibility, super elasticity, force hysteresis, shape memory effect, excellent corrosion, torquability, less sensitivity to magnetic resonance imaging and biomechanical compatibility.
      • The shape memory alloys possess the ability to
      • undergo shape change at low temperature and retain
      • this deformation until they are heated, at which point
      • they return to their original shape.
    •  
      • The failure rate for surgeries using classical plates is 30-40% due to the following:
      • The absence of continuous compression
      • Extensive destruction of soft tissue
      • Extensive destruction of blood vessels. Due to this, the nutrient filled blood can not reach the fracture and healing is not achieved.
      • Frequent infections because of the large incisions.
      • The design idea of modular adaptive orthopedic implants results from the following observations:
      • - the doctors have a limited degree of freedom in selecting the proper dimensional devices for bones fractures;
      • - the current mechanical devices used in orthopedics don’t ensure a permanent contact and a continue compression to the fractured parts of the bone;
      • to develop bone calluses, to recovery the bone and to improve the healing process, it is essential that the fractured parts have to be in permanent contact, have to be anatomical reduced and it is necessary to be exerted a continue compression;
      • The first option for our team it is focused on creating a modular adaptive plate for fracture bone osteosynthesis, realized from modules completely interchangeable, made of titanium or stainless steel and from connecting elements as U-shaped staples made of Nitinol.
      • Modules for the diaphiseal region of the long bones:
      • Modules and modular plates for the diaphiseal and epiphiseal regions of the long bones:
    •

    •  
      • Conclusions for the modular orthopedic plates:
      •   1.The adaptive modular implants based on smart materials represent a superior solution in the osteosynthesis of the fractured bones over the conventional implants known so far. This conclusion is validated by in vitro and in vivo experiments.
      • 2.The superiority of this design
      • a) their structure is based on small modules which can be mounted easily on the bone and can be used for every region of the bone,
      • c) by combining a certain number of modules, we can obtain implants with various lengths depending of type, position or dimension of the fracture;
      • d)the possibility of mounting the Nitinol staple to the modules near the fracture enables the stabilization and the rigidity of the implants as well as the good compaction and the good union of the bone fractures, which are essential restrictions in the healing process.
      • -decrease in soft tissues destruction;
      • -decrease in the intra-operator infections;
      • -decrease in blood losses;
      • -decrease in infection risk;
      • -decrease in the healing time for the plagues;
    • Thank you and Good luck !
