Abstract: The atlas (first cervical vertebra) has undergone many structural modifications. It is critically located and close to the 'life centres'. For this study, one hundred dried intact human atlas vertebrae from the Indian population were measured using a digital Vernier calliper that provides accurate resolution up to 0.01 mm. The distance between the tips of the transverse process, the outer and the inner distance between the foramen transversaria and various diameters of vertebral foramen were measured. The mean width of the measured atlases was 69.37 mm. The mean distance between the lateral margins of foramen transversaria was 55.66 mm and the inner distance was 45.93 mm. The mean thickness of vertebral artery grooves was 3.72 ± 1.06 mm. The observations made in the present study may help in improving understanding of various bony dimensions while operating close to important structures like nerve roots and the vertebral artery.

Key Words: Atlas, Atypical cervical vertebra, C1, morphology.

BACKGROUND The management of unstable atlas fractures remains a subject of ongoing debate and controversy. The conservative surgical treatment commonly involves fusion, resulting in severe loss of cervical spine mobility, and a large incisions and extensive tissue dissection are required. We aim to introduce a novel concept and surgical approach for treating atlas fracture, one that involves minimizing trauma while maintaining mobility of the upper cervical spine without resorting to fusion.

Objectives: To analyze the risk factors for developing dysphagia after occipitocervical fusion (OCF) and investigate possible mechanisms and prognosis.

Methods: The case data of 43 patients who underwent OCF were retrospectively reviewed. Patients were divided into group A (dysphagia group) and group B (non-dysphagia group) based on Bazaz scoring criteria.

Cervical fracture dislocation often leads to neurological deficits, manifesting with sensory and motor symptoms, which may persist even after surgical intervention. We presented two cases with mild neurological deficits following such injuries. In Case 1, the patient presented with left-hand numbness 1 month after a car accident.

Introduction: Pain from the cervical facet joints, either due to degenerative conditions or due to whiplash-related trauma, is very common in the general population. Here, we provide an overview of the literature on the diagnosis and treatment of cervical facet-related pain with special emphasis on interventional treatment techniques.

Methods: A literature search on the diagnosis and treatment of cervical facet joint pain and whiplash-associated disorders (WAD) was performed using PubMed, Cochrane, and Embase databases.
