METHOD FOR HIP FRACTURE OSTEOSYNTHESIS AND DEVICE FOR IMPLEMENTING IT Russian patent published in 2016 - IPC A61B17/74 

FIELD: medicine.

SUBSTANCE: fenestrated cannulated compression screw comprises a cylindrical rod of an external diameter of 4-8 mm from a proximal portion and 9-11 mm from a distal portion, 40-120 mm long, with an axial through hole to make it possible to insert the screw along a pin during the osteosynthesis process and supply osteogenesis stimulating substances into the fracture area; the cylindrical rod is provided with an external thread formed from the distal and proximal portions of the screw, as well as with the holes created in a rod wall. Some holes are arranged between the proximal and distal portions on its smooth surface and oval-shaped and configured on the cylindrical rod to ensure a uniform distribution of the substances supplied along an axial passage within the fraction; some holes are provided on the thread of the proximal portion and have dimensions smaller than the oval-shaped holes; total area of the holes on the cylindrical rod makes 40-100 mm². A method for hip fracture osteosynthesis involves inserting three cannulated compression screws, two of which are provided with a proximal thread, whereas the third one - according to patent claim 1.

EFFECT: reliable fixation and reduced length of treatment.
