The 2020 July Issue of Neurosurgical Focus: Video Demonstrates Surgical Procedures for Craniocervical Deformity and Instability

Charlottesville, VA (July 1, 2020). The July issue of Neurosurgical Focus: Video (Vol. 3, Issue 1 []) features nine video articles and an editorial on surgeries for craniocervical deformity and instability. An introduction to the issue is provided by the July topic editors: P. Sarat Chandra, Douglas Brockmeyer, Ehud Mendel, and Sushil V. Patkar. 

According to the July topic editors, 

“The following video section on craniovertebral junction specifically deals with techniques that have evolved in the past decade demonstrated by the masters. The techniques presented here range from intra-articular distraction with cage placement (Duan et al.), joint disarticulation techniques for correcting cervical kyphosis (Katzir et al.), mobilization of the vertebral artery while performing C1–2 fixation (Goel), endoscopic endonasal odontoidectomy (Ruiz-Garcia et al.), and navigated transoral odontoidectomy (Duan et al.) to more complex procedures, such as C1 lateral mass hypertrophy (Iyer and Brockmeyer), the DCER technique using a specially designed universal reducer (Chandra), use of special [variable screw placement] plates to reduce atlantoaxial dislocation (Patkar), and an anterior retropharyngeal approach for cage placement and fixation (Patkar). Overall, the varied plethora of cases should not only be of interest for the beginner but also challenge the like of experts.” 

The July issue contains the following: 

  • “Introduction. Intraoperative manipulation, reduction, realignment, and deformity reduction in patients with atlantoaxial dislocation and basilar invagination” by P. Sarat Chandra et al. 
  • “Posterior intra-articular distraction with cage placement to treat congenital atlantoaxial dislocation associated with basilar invagination” by Wanru Duan et al. 
  • “Endoscopic endonasal odontoidectomy for the treatment of basilar invagination” by Henry Ruiz-Garcia et al. 
  • “Mobilization of the high-riding vertebral artery for C2 screw insertion” by Atul Goel 
  • C1–2 facet disarticulation for correction of iatrogenic cervical kyphosis following occipital-cervical fusion” by Miki Katzir et al. 
  • “C1 hypertrophic lateral mass resection and occiput–C2 fusion” by Rajiv R. Iyer and Douglas L. Brockmeyer 
  • “Editorial. Are there any indications of transoral odontoidectomy today?” by P. Sarat Chandra 
  • “Navigated transoral odontoidectomy to treat congenital basilar invagination after failed posterior reduction and fusion” by Wanru Duan et al. 
  • “A case of severe basilar invagination and AAD, corrected using the technique of DCER—distraction, compression, extension, reduction (with spacer + universal reducer)” by P. Sarat Chandra and Mohit Agarwal 
  • “Posterior atlantoaxial fixation with new subfacetal axis screw trajectory avoiding vertebral artery with customized variable screw placement plate and screws to enhance biomechanics of fixation” by Sushil Patkar
  • “Anterior retropharyngeal cage distraction with atlantoaxial plate-screw fixation for basilar invagination with atlantoaxial dislocation” by Sushil Patkar


The topic editors wish you “Happy viewing!”

Founded in 1931 as the Harvey Cushing Society, the American Association of Neurological Surgeons (AANS) is a scientific and educational association with more than 10,000 members worldwide. The AANS is dedicated to advancing the specialty of neurological surgery in order to provide the highest quality of neurosurgical care to the public. All active members of the AANS are certified by the American Board of Neurological Surgery, the Royal College of Physicians and Surgeons (Neurosurgery) of Canada, or the Mexican Council of Neurological Surgery, AC. Neurological surgery is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders that affect the entire nervous system including the brain, spinal column, spinal cord, and peripheral nerves.
