A Novel Technique for Basilar Invagination Treatment in a Patient with Klippel–Feil Syndrome: A Clinical Example and Brief Literature Review

This paper describes a new surgical technique to treat a rare condition where the top of the spine pushes into the skull, compressing the brain. This is called basilar invagination. The patient also had Klippel-Feil Syndrome, where neck bones are fused together. The new technique uses a posterior approach, O-arm navigation, and doesn't require a C-arm fluoroscopy. The surgery successfully decompressed the spinal cord, and the patient's symptoms improved significantly. The technique aims to be safer and more precise than traditional methods.

• 1
  The novel C-arm-free posterior approach with O-arm navigation was effective in reducing basilar invagination and decompressing the spinal cord.
• 2
  The patient experienced significant clinical improvement, with almost full recovery of motor and sensory function in the upper limbs and improved gait.
• 3
  The technique allowed for precise placement of occipital screws in the thickest part of the skull under navigation guidance, minimizing the risk of complications and radiation exposure.
