Anterior Transoral Odontoid Reduction With Clivocervical Fusion in Revision Surgery for Craniovertebral Junction Anomalies: A Case Report and Technical Note

Orthopaedic Surgery, Volume 18, Issue 1, Page 194-201, January 2026.
For revision CVJAs with persistent ventral compression after failed posterior fixation, anterior transoral odontoid reduction combined with clivocervical fusion achieved direct decompression, restored clivo‐axial angle, resolved spinal cord compression, and provided stable fusion with significant neurological recovery, offering an effective salvage ...

The management of os odontoideum. Analysis of 37 cases

, 1982
Thirty-seven patients treated for os odontoideum are reviewed. In 20 patients the treatment was conservative and in 17 consisted of occipitocervical or atlanto-axial fusion.

Feasibility and Safety of the C1 “Zero Angle” Screw: A Novel “In–Out–In” Technique for Atlantoaxial Dislocation

Orthopaedic Surgery, Volume 17, Issue 2, Page 437-445, February 2025.
The C1ZAS with “in–out–in” technique is presented as an alternative to C1 PS in cases of AAD with a trajectory parallel to the sagittal plane. This method involves penetrating the recess of the atlas to achieve tricortical or quadricortical purchase for rigid fixation while minimizing the risk of injury to the V3 segment of the VA.

Analysis of Failed Atlantoaxial Reduction: Causes of Failure and Strategies for Revision

Orthopaedic Surgery, Volume 16, Issue 11, Page 2741-2750, November 2024.
Severe atlantoaxial joint locking or ligament contracting are the fundamental cause of reduction and fixation failure. Anterior odontoidectomy is indicated for patients with robust bony fusion of the atlantoaxial joint in an unreduced position, the PFDF technique indicated for patients with incomplete bony fusion. Objective The craniovertebral junction

Os Odontoideum Mimicking Acute Odontoid Peg Fracture

, 2015
The atlantoaxial complex is a common site for cervical spine injuries, of which fractures of the axis (C2), occur most frequently. Over half of these fractures involve the odontoid process.

Aqueductal stenosis and mental retardation associated with O S odontoideum, "hypermobile" atlantoaxial dislocation and congenital stenosis of atlas leading to spastic quadriparesis

Journal of Pediatric Neurosciences, 2007
Background: The authors report a unique concomitant occurrence of mental retardation, hydrocephalus due to aqueductal stenosis, a freely floating atlas (having anterior, posterior and transverse atlantoaxial dislocation [AAD]) consequent to an orthotopic

Anatomy and mobility in the adult cadaveric craniocervical junction 

Journal of Morphology, Volume 285, Issue 7, July 2024.
The motivation of the present study was to understand the morphological and functional basis of motion in the adult craniocervical junction, in the hope to find morphological features accessible from medical imaging able to predict mobility. We compared a wide range of mobility variables extracted from an experimental setup, with the shape of the ...

Three neglected cases of minor trauma to the craniovertebral junction with potentially disastrous consequences

CHRISMED Journal of Health and Research, 2015
Os odontoideum is a rare congenital anomaly predisposing to atlantoaxial instability. It may rarely present with a history of trivial trauma followed by slow progressive features of compressive myelopathy.
