The classic "blowout fracture" is the result of a blow to the anterior orbit, which increases retroglobar pressures thus breaking the weakest portion of the bony orbit, the medial floor.

All 16 patients with odontoid fracture underwent anterior screw internal fixation. Following-up ranged from 6-40 months, the fracture in all cases were bony healed and no complication.

INFUSE is highly effective in promoting cervical spine fusion via an anterior approach, but its potential role in promoting bony fusion in posterior cervical or OC fixation has not been studied.
