A 56-year-old female patient was admitted with a history of pain during neck movements after cervical injury. Computerized tomography scan revealed type II odontoid fracture and fusion anomaly between C2 and C3 vertebrae. At surgery, the anteroinferior part of C2 vertebra corpus could not be reached; therefore, transodontoid screw was advanced from C3 vertebra toward odontoid process. At follow-up examination, the complaints of the patient had recovered, and fracture line was completely fused. Advancing screw from C3 to odontoid process via anterior cervical approach could be thought an alternative treatment option in the patient with short neck caused from vertebra fusion anomaly and/or obesity.

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.

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.

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.

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.

Objective: The endoscopic endonasal approach (EEA), has become the preferred alternative to traditional open and transoral approaches to the ventral craniovertebral junction (CVJ) region. However, preoperative prediction of the limitations of caudal reach remains challenging. This cadaveric study aimed to quantify the CVJ area of exposure and access afforded by the EEA, evaluate the accuracy of previously described radiographic anthropometric lines, and identify the lowest limit of the EEA corridor.
