Symmetry is pervasive across the tree of life, and organisms (including humans) build symmetrical structures for reproduction, locomotion, or aesthetics. Symmetry, however, does not necessarily span across levels of biological organization (e.g.

Objectives: Atypical hangman's fractures are associated with increased risk for neurologic injury due to involvement of the posterior cortex of the axis body. We present the largest single-center cohort of atypical hangman's fractures with the goal of guiding treatment decisions and outcomes based on fracture classification.
Background: Several assessment tools have been developed to estimate a patient's likelihood risk of falling. None of these measures estimate the contributions of the visual, vestibular, and somatosensory systems to fall risk, especially in patients with degenerative lumbar spine disease.
Methods: Degenerative lumbar spine patients with radiculopathy (LD) and healthy subjects who were 35-70 years old without spine complaints were recruited.
