DEVICE FOR OSTEOSYNTHESIS Russian patent published in 2007 - IPC A61B17/68 

FIELD: medicine; traumatic surgery; orthopedics.

SUBSTANCE: device is made of shape memory effect titanium nickelide and it has elongated frame made of two wires, twisted into bundle. Pairs of half-wave curves of any wire are distributed along length of frame. Curves together and opposite stay apart from bundle. Wires have ends for intraosteal fixation; ends are bend to meet each other in same plane. Planes of one-sided half-wave curves are oriented in plane of device to have the same direction as bend ends of wires for intraosteal fixation and they intend to be placed inside bone. Opposite half-wave curves of any pair are oriented in orthogonal to plane of device, alternatively to different sides along length of frame. Angle of bend of wire ends equals to 100-120°. Device provides prevention of risk of letting device for osteosynthesis go from bone in case when oblique and comminuted fractures of tubular bones have to be treated.

EFFECT: prevention of axial instability of bone fractures.
