Atlantodentoplasty using the anterior retropharyngeal approach for treating irreducible atlantoaxial dislocation with atlantodental bony obstruction: a retrospective study.
Asian Spine J
January 2025
Department of Spinal Surgery, Henan Provincial People's Hospital, Zhengzhou, China.
Study Design: This was a retrospective study.
Purpose: The current study aimed to investigate the clinical efficacy of atlantodentoplasty using the anterior retropharyngeal approach against irreducible atlantoaxial dislocation with atlantodental bony obstruction.
Overview Of Literature: In cases of atlantoaxial dislocation with atlantodental bony obstruction, owing to the presence of an osteogenic mass between the atlas and odontoid process, reduction is challenging to complete using the posterior approach.
The effect of cervical spine flexion-extension motion on odontoid parameters.

Department of Spine Surgery, The First Affiliated Hospital of Guangxi Medical University, 6 Shuangyong Road, Guangxi Zhuang Autonomous Region, Nanning, 530021, China.
Objective: To assess the stability of odontoid parameters on flexion-extension motion and to validate the accuracy of the physiological cervical lordosis (CL) predictive formula across different cervical positions.
Methods: Standard cervical spine lateral radiographs in neutral, flexion, and extension positions were collected to measure odontoid incidence (OI), odontoid tilt (OT), C2 slope (C2S), CL, T1 slope (T1S), and T1S minus CL (T1S-CL). Friedman's test was used to assess the differences in parameters among the three cervical spine positions.
[Treatment of geriatric odontoid fractures].

The treatment of odontoid fractures in geriatric patients, particularly type II fractures, remains controversial. In biologically young patients, studies suggest advantages of surgical treatment in terms of mortality; however, this advantage is not observed in geriatric patients. While the mortality appears to be higher after conservative treatment in patients aged 65-80 years, there are studies that have shown no differences in mortality for patients aged 80 years or older and even showed advantages of conservative treatment in this age group.

J Neurosurg Case Lessons
January 2025
Departments of Neurosurgery, NYU Langone Health, New York, New York.
Background: Aneurysmal bone cysts (ABCs) are slow-growing, expansile bone tumors most often observed in the long bones and lumbar and thoracic spine. Anterior column ABCs of the spine are rare, and few cases have described their surgical management, particularly for lesions with extension into the odontoid process and the bilateral C2 pedicles. In the present case, the authors describe a two-stage strategy for resection of a symptomatic 2.

The First Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, 510405, China.
Objective: This study presents a novel odontoid parameter, the odontoid incidence (OI), to examine the correlation between OI on preoperative cervical sagittal radiographs and 2-year clinical outcomes following short-segment anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylotic myelopathy (CSM).
Methods: A retrospective analysis of the clinical data of 87 patients with CSM who underwent ACDF surgery from January 2018 to December 2023 was conducted. The patients were categorized into a larger OI group (44 patients, OI > 12.
