METHOD FOR STABLE OSTEOSYNTHESIS ACCOMPANYING BONE TISSUE INJURIES Russian patent published in 2014 - IPC A61L27/04 A61N1/20 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for a stable osteosynthesis accompanying treating bone tissue injuries (endoprosthesis replacement, delayed union, false joints, chronic osteomyelitis). The stable osteosynthesis accompanying the bone tissue injuries involves using a bimetallic implant with various electrochemical potentials introduced into the bone tissue for inducing the bone tissue regeneration. The novel problem solution is using the bimetallic implant made of titanium and platinum with the total electrode potential difference 600 mV. The injuried bone tissue is exposed to an anode-polarised titanium component of the implant until observing a synthesis of the bone tissue continuity. The presented 'method for the stable osteosynthesis accompanying the bone tissue injuries' as compared to the known techniques enables combining all positive points of using metal structures complying with the current state of structures for the bone fracture osteosynthesis, and also provides polarisation of the components of the bimetallic implant, namely the anode polarisation of the titanium surface as a metal, directly contacting an internal environment of the bone that enables optimising the osteorepair process at the boundary of 'implant-bone' by the qualitative change of the regenerate and thereby providing more stable fixation of the metal structure.

EFFECT: method is widely used in medicine for optimising the osteorepair in the compromised osteogenesis (endoprosthesis replacement, delayed union, false joints, chronic osteomyelitis).
