SCREW FOR BRACING OF FRAGMENTS OF DAMAGED ODONTOID PROCESS OF SECOND CERVICAL VERTEBRA

摘要

FIELD: medicine.;SUBSTANCE: invention concerns medicine, namely, traumatology and neurosurgery. Screw contains a working part with a carving and a head with a recess for a screw-driver. The screw is executed with the through longitudinal channel in a working carving part the longitudinal apertures in at least, two numbers on all length are executed. The edge of apertures, lateral along the screw movement, is executed cutting, and interfacing to a cutting edge screw thread end faces are executed with a cutting side. The working part is executed by diameter 6-7 mm at length of 30-45 mm with an external rough surface. The screw end face is executed with external sharpening and the sphenoidal grooves referred against a course of screw cutting.;EFFECT: rising of medical effect at the expense of improvement of stability of fracture maintenance fragments bracing, of optimal conditions of consolidation for acute and inveterate damages of odontoid process of the second cervical vertebra.;3 dwg
