METHOD FOR DISTANCE BLOCKING OF CANNULATED RODS Russian patent published in 2017 - IPC A61B17/72 

FIELD: medicine.

SUBSTANCE: distal target guide is prepared, aligning the holes in the distal target guide block with the holes on the cannulated stem, which has an upper distal opening and a lower distal opening. The cannulated rod is directed along the guide spoke into the medullary canal. Through the upper distal aperture in the distal target guide block, a drill is used to form a bone channel for the locking screw, drill passage through the rod upper distal opening is controlled by a guide pin located in the rod channel. When the direction in the channel formed in the bone corresponds to the rod upper distal hole, the locking screw is inserted through the sleeve, locking screw passage through the rod upper distal opening is controlled by a guide pin located in the rod channel. A channel is formed in the bone through the lower distal opening in the distal target guide block and the rod lower distal opening. A locking screw is introduced into the formed channel.

EFFECT: method allows to reduce the number of intraoperative X-ray studies, provide the possibility of blocking without EOC.
