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.

Article Synopsis
  • The study investigates the feasibility, safety, and effectiveness of mobilizing the vertebral artery for inserting C2 pedicle screws in patients with a high-riding vertebral artery (HRVA).
  • A total of 15 patients underwent successful posterior occipitocervical fixation from January 2020 to September 2022, with the procedure allowing safe placement of screws and no reported complications.
  • Post-surgery results showed effective screw placement and successful bone fusion within six months, with no significant issues related to the surgery or neurological function.

Influence of the type of atlantoaxial dislocation secondary to os odontoideum on sagittal alignment and balance of the subaxial cervical spine after posterior atlantoaxial fusion.

Department of Orthopedics, Shanghai Changzheng Hospital, Naval Medical University, 415 Fengyang Road, Huangpu District, Shanghai, 200003, People's Republic of China.

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.

Article Synopsis
  • Management of type II odontoid fractures remains debated, with this study focusing on the biomechanical roles of specific ligaments in the craniovertebral junction.
  • A finite element model was used to simulate different injury conditions and examine how these fractures affect spinal stability during various movements.
  • Results indicated that while the type II odontoid fracture is the main source of instability, the vertical cruciate and transverse ligaments contribute modestly to stabilization, whereas the alar ligament has little to no stabilizing effect.
