Outcomes of Odontoid Process Fracture Surgery

Ortopedia Traumatologia Rehabilitacja, 2023
Background. Odontoid fractures are found in two age groups. In younger patients, they occur following traffic accidents, falls from a height and during sports. In older patients with poor bone quality, they are usually caused by falls from one’s own height. Most fractures are stable and do not require surgical treatment.

The Odontoid Process

2020
The odontoid process was once thought to be a displaced body of the atlas but is now believed to have separated from the anterior part of the atlas between the sixth and seventh week of gestation and to have migrated caudally to fuse with the body of the axis.

Pseudomalignant osteoblastoma of the odontoid process

European Spine Journal, 2018
The anterior elements of the spine, particularly the odontoid processes, are a rare location for osteoblastomas. Pseudomalignant osteoblastomas are themselves rare histologic types and are also extremely rare in this location. Most osteoblastomas are Enneking stage 2 lesions; less frequently, they can be more aggressive with extra-capsular extension ...

The Internal Trabecular Bone Structure of the Odontoid Process of the Axis: A Retrospective Single-Center Comparative Study in Patients Following Cervical Trauma

Central European Neurosurgery, 2022
Background Odontoid C2 fractures account for 9 to 15% of adult cervical spine fractures. The aim of this study is to report the incidence of a previously described Y -shaped trabecular bone structure (TBS) in the odontoid process in a larger sample of ...

Retroodontoid pseudotumor: Two cases of intradural ganglion cysts arising from the odontoid process with syringobulbia.

World Neurosurgery, 2020
BACKGROUND Ganglion cysts mostly occur in the knuckles and wrists, but they rarely present in the odontoid process and can cause neurological symptoms by compressing the spinal cord.

Predictors of mortality in the elderly patient with a fracture of the odontoid process: CAN WE USE NON‐SPINAL SCORING SYSTEMS?

The Bone & Joint Journal, 2019
Aims Fracture of the odontoid process (OP) in the elderly is associated with mortality rates similar to those of hip fracture. The aim of this study was to identify variables that predict mortality in patients with a fracture of the OP, and to assess ...

Agenesis of the Odontoid Process

Radiology, 1956
Failure of ossification of the odontoid process of the second cervical vertebra is a rare developmental anomaly which may be asymptomatic for many years. As a result of more thorough roentgenologic examinations, the condition has been noted with increasing frequency since its original description by Roberts in 1933 (1).

Surgical treatment of neglected C2 odontoid process fracture with anterior atlantoaxial dislocation

British Journal of Neurosurgery, 2020
We report a case of the atlantoaxial (C1–2) deformity secondary to a neglected C2 odontoid fracture that was successfully treated with 3-stage operation performed in one session.

Osteomyelitis of the Odontoid Process

Journal of Spinal Disorders, 1988
Pyogenic osteomyelitis of the odontoid process is a rare condition requiring a high index of suspicion for diagnosis. The three cases presented illustrate that patients with severe neck pain, aggravated by rotation, and persistent fever without apparent source should be studied carefully to exclude infection of the C1-C2 area.
