Study Notes

Water hammer is not mentioned in the text.
Concussion is an injury to the brain caused by impact resulting in neurological deficits.
Sports-related concussion is hard to diagnose as symptoms are not always consistent.
Lateral and oblique forces are bad for the brain, while sagittal plane impact is better due to shear modulus.
The fencing response hints at damage to the brainstem.
Autonomic dysfunction is a dysfunction in the regulation of the parasympathetic and sympathetic nervous system.
Red flags for concussion include headache, dizziness, nausea, vomiting, increased symptoms or severity, and seizures.
Facet joints in spinal joints help with compressive forces up to 50%.
The normal shape of the C spine is lordosis, and a breakdown in that shape can occur with axial loading and compression forces with neck flexion.
Children are more likely to sustain neck injuries in C1-4 as their head is much larger in proportion to their neck.
