TELESCOPIC FENESTRATED CANNULATED COMPRESSING SCREW FOR OSTEOSYNTHESIS OF LIMB BONE FRACTURES Russian patent published in 2017 - IPC A61B17/74 A61B17/76 A61B17/78 

FIELD: medicine.

SUBSTANCE: invention can be used to treat various fractures that require approchement of fragments with accelerated adhesion, particularly in osteosynthesis of hip, tibialis and hip condylaris fractures, tibial syndesmosis, Pylon fractures, ulnar process, shoulder condyles, inner ankle fractures, etc. The device for osteosynthesis of femoral neck fractures is a fenestrated cannulated compression screw consisting of two rods, distal and proximal, made with through axial channels with a possibility of telescopic connection of the rods, and holes in the walls of the rods that provide the fracture zone with substances that stimulate osteogenesis. Each of the rods is provided with a threaded portion for screw engagement with the femoral neck bone material.

EFFECT: invention provides a more effective fixation of fracture fragments, accelerated bone fusion with a decrease in side effects and postoperative complications associated with distal screwmigration in limb bones during fracture healing.
