Introduction: The aim of this article is to present the diagnostic and therapeutic approach to unilateral posterior vertical insufficiency.
Material And Methods: The authors describe the management protocol.
Results: Posterior vertical insufficiency (PVI) manifests clinically as obliquity of the maxillo-mandibular occlusal plane and bicommissural line, and deviation of the chin.

Introduction: Global coronal alignment is mainly assessed by C7 plumbline and central sacral vertical line (CSVL), pelvic obliquity and shoulder alignment. A detailed analysis is mandatory when treating spinal deformity. It remains unclear to what extent mild scoliosis influences global coronal alignment.

Objective: This retrospective study aims to investigate the effect of the type of atlantoaxial dislocation due to os odontoideum on the sagittal alignment and balance of the cervical spine after posterior atlantoaxial fusion.
Methods: Data of 48 consecutive patients who underwent posterior C1-C2 fusion to treat atlantoaxial dislocation/instability due to os odontoideum were retrospectively reviewed. Radiographic variables, namely the T1 slope (T1S), C1-C2 angle, C2-C7 angle, C1-C2 sagittal vertical axis (SVA), C2-C7 SVA, and modified atlas-dens interval (MADI), were measured preoperatively, immediate postoperatively, and at final follow-up.
