FIELD: medicine, traumatology, orthopedics.
SUBSTANCE: the present innovation deals with fixing osseous fragments in case of a foreign body in medullary cavity (intramedullary rod, endoprosthesis' pedicle, etc.). Extracortical fixing device contains a shaft to be fixed to the support of compression-distraction apparatus designed as a hollow rod with internal thread, an immersion part for the contact with a bone as parallel hook-like grips at curvature radius being above the haft of osseous circumference and eccentrically connected with the shaft, a clamping sharp rod at external end to be screwed into the shaft. The innovation provides insignificant traumatism during interference, excludes the damage of the main vessels and nerves.
EFFECT: higher efficiency of fixation.
