Results of Surgical Fixation of Occipitocervical Instability Using Polyaxial Plate/Rod System. Report of 14 Cases.

Abstract

Background Data: Occipitocervical junction instability has always been a challenging surgical problem owing to the unique anatomical and biomechanical characteristics of this region. Purpose: To detect the safety, efficacy and related complications using polyaxial screw-based constructs with rod / plate system for occipitocervical instability. Study design: This is a retrospective study for 14 patients underwent occipitocervical fusion for instability using polyaxial screw-based constructs with rod / plate system during the period from
