METHOD FOR REDUCTION OF FRAGMENTS IN CLOSED INTRAMEDULLARY OSTEOSYNTHESIS OF HUMERAL NECK FRACTURES Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: minimally invasive transdeltoid approach, opening into a subacromial space and dissection of a rotatory cuff with a long two-centimetre incision from an edge of a greater tubercle to the centre of a humeral head; an EOP-assisted awl is introduced into the humeral head from the greater tubercle to the centre of the head downright and rotated downright to eliminate an incomplete dislocation; the greater tubercle is reduced; and the head is directed in the position optimal for introducing a nail wherein the head is fixed to an articular process of a shoulder blade using two pins introduced through a lesser tubercle from the front and through the greater tubercle at the backside of the canal from a rod canal formed in the geometrical centre of the humeral head. The head is matched with a distal fragment, and the rod is introduced into the canal, and the head, tubercles and diaphysis are fixed using altitude clamps. The temporary pins are removed thereafter.

EFFECT: method enables matching the humeral fragments, providing the optimum conditions for the intramedullary osteosynthesis ensured by the reliable temporary head fixation.
