METHOD FOR DETECTING SAFE AREAS FOR INTRODUCING FIXATORS INTO A VERTEBRA AND A MARKING PATTERN FOR ITS IMPLEMENTATION Russian patent published in 2006 - IPC A61B17/56 A61B6/03 A61B6/00 A61B17/64 A61B17/60 

FIELD: medicine, orthopedics, traumatology.

SUBSTANCE: the present innovation deals with applying surgical instruments and ways for treating motor system by introducing fixators into a vertebra. It is necessary to fulfill a roentgenogram of deformed vertebral column in frontal projection, then its contour should be identified with that of a marking pattern which should be matched with the centers of bows' roots. Then one should apply needles-marks upon a pattern in transverse plane by matching them with the centers of bows' roots followed by computer tomography at the pictures of which one should detect the angle for introducing fixators, free ends of needles-marks should be curved by matching with the angle of introducing fixators. In operation room, one should place a marking pattern at a patient's back by matching it with the contour of patient's vertebral column followed by roentgenological control, then it is necessary to introduce fixators into bows' roots taking into account the position of needles-marks. Marking pattern contains two supports made of plastic material. Every support has got through steadily located openings and not less than 2 needles-marks. They are designed to be introduced through the openings. Moreover, free ends of needles-marks are designed to have the chance for curvature. Application of the present method enables to shorten the duration of operative interference and, also, decrease the number of roentgenological trials during interference.

EFFECT: higher accuracy and efficiency of detection.
