METHOD OF ANTERIOR TRANSORAL ATLANTO-OCCIPITAL STABILIZATION Russian patent published in 2019 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neurosurgery, and can be used for stabilization in the atlanto-occipital articulation in various pathological states of this localization.
