Mechanically Relevant Anatomy of the Axis Vertebra and Its Relation to Hangman’s Fracture: An Illustrated Essay [PDF]

Neurospine, 2019
To describe the biomechanically relevant anatomy of the Axis vertebra and the load transfer patterns within the bone, and on that basis, to postulate its mechanism of injury, a literature review was conducted of the anatomy and biomechanics of Axis ...

External Load of Flamenco Zap-3 Footwork Test: Use of PlayerLoad Concept with Triaxial Accelerometry

Sensors, 2022
The intense footwork required in flamenco dance may result in pain and injury. This study aimed to quantify the external load of the flamenco Zapateado-3 (Zap-3) footwork via triaxial accelerometry in the form of PlayerLoad (PL), comparing the difference

Conjoined first (atlas) and second (axis) cervical vertebrae in an eastern wapiti (Cervus canadensis canadensis) from the Angel Site (1000–1400 CE, Indiana, USA)

International Journal of Osteoarchaeology, 2023
AbstractAtlantoaxial abnormalities are rarely documented among wild animals. Many defects of segmentation in the spine are hereditary in domestic species and humans. Here, we present a block vertebra in an eastern wapiti (Cervus canadensis canadensis) from the Angel Site (12Vg1) in southern Indiana (USA) dating to 1000–1400 CE.

Cryptic complexity in felid vertebral evolution: shape differentiation and allometry of the axial skeleton [PDF]

, 2016
Members of the mammalian family Felidae (extant and extinct cats) are grossly phenotypically similar, but display a 300-fold range in body size, from less than 1 kg to more than 300 kg.

Osteolytic mass bridging two cervical vertebrae: Unusual presentation of a vertebral body hemangioma

Radiology Case Reports, 2014
Vertebral hemangioma is the most common spinal axis tumor. This rare presentation of a vertebral hemangioma extended contiguously from one cervical vertebra to another, encasing the vertebral artery, and thereby mimicking other tumors of the spine.

Fusion of axis with third cervical vertebra: a case report

Romanian Neurosurgery, 2016
Abstract Introduction: Fusion of one or more contiguous vertebral segments is usually the result of embryological failure of normal spinal segmentation. It may be associated with syndromes such as Klippel-Feil. Fused cervical vertebrae (FCV) may also be acquired or pathologic. FCV is generally associated with disease like tuberculosis, other infections,
