Craniocervical instability is caused by trauma(s) to the head and neck areas such as concussion and whiplash. Ligaments in neck are unable to heal properly, so the neck structure does ...
Atlanto-occipital dislocation. Atlanto-occipital dislocation, orthopedic decapitation, or internal decapitation describes ligamentous separation of the spinal column from the skull base. It is possible for a human to survive such an injury; however, 70% of cases result in immediate death. It should not be confused with atlanto-axial dislocation ...
Clay-shoveler's fracture is a stable fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae, classically at C6 or C7. [1] In Australia in the 1930s, men digging deep ditches tossed clay 10 to 15 feet above their heads using long handled shovels. [2]

Essex-Lopresti fracture. The Essex-Lopresti fracture is a fracture of the radial head of the forearm with concomitant dislocation of the distal radio-ulnar joint along with disruption of the thin interosseous membrane which holds them together. [1] The injury is named after Peter Essex-Lopresti who described it in 1951.
