title: Posterior C1-2 Fixation with cancellous screw and rod system for retro-odontoid pseudotumor associated with chronic atlantoaxial subluxation. Technical note.
abstract: Posterior C1-2 fixation with individual screw placement in C-1 and C-2 was performed in three patients presenting with progressive myelopathy caused by retro-odontoid pseudotumor associated with chronic atlantoaxial subluxation. Postoperatively, all patients demonstrated neurological recovery with gradually diminishing pseudotumor. Posterior C1-2 fixation with the cancellous screw and rod system is a safe and reliable method, and can be used to treat retro-odontoid pseudotumor associated with chronic atlantoaxial subluxation.
