METHOD FOR OSTEOSYNTHESIS OF STERNAL FRACTURES Russian patent published in 2003 - IPC

FIELD: medicine, orthopedics, traumatology. SUBSTANCE: one should conduct reposition and fixation of osseous fractures with the help of special alloy-made device with the memory of shape in the form of opened ring with shoulders and fixing stems which should be cooled and deformed before installation. Device's stems are arc-wise curved in the plane perpendicular to that of the ring and directed towards opposite sides against the center. It is necessary to form the channels in sternal fractures to install device's stems through external cortical plate and porous substance up to internal cortical plate being directed towards opposite sides against the fracture. Device's stems are placed between cortical sternal plates. Plate made of porous nitinol is installed under device's osseous part. In peculiar case, plate of porous nitinol has thickness value of 0.05 cm and linear sizes corresponding to those of device's osseous part. In peculiar case, to create compression in fracture area during osteosynthesis one should deform the device after cooling it by increasing the distance between stems. In peculiar case, to create distraction in fracture area during osteosynthesis one should deform the device after cooling it by decreasing the distance between the stems. In peculiar case, during osteosynthesis in neutral position one should deform device after cooling it by not changing the distance between the stems. The present method enables to provide stability of osteosynthesis, decrease traumaticity level, optimize reparative processes in fracture area. EFFECT: higher efficiency of operation. 4 cl, 8 dwg, 1 ex
