ring fracture

An annular bone fracture at the base of the posterior fossa around the foramen magnum, which is accompanied by compression fractures of vertebrae and blunt trauma to soft tissue.

Mechanism
Fall or jump from heights, usually > 5 stories, onto the feet or buttocks. If the kinetic energy is not absorbed by skeletal compression, the cervical spine is forced into the skull, breaking off a rim of occipital bone or, less commonly, impacting the cranial vault.

Vertical deceleration injury Trauma medicine A type of blunt trauma due to jumping or falling from heights, usually > 5 stories Clinical Injury severity score is 41–predicted survival, 50%; actual survival is less; all had multiple fractures–eg, 'ring fracture' of the skull base, separating the rim of the foramen magnum from the rest of the base and compression fractures of vertebrae, both of which occur when the victim lands on his/her feet or buttocks. See Jumper syndrome.
