Biomechanical comparison of cemented vs. non-cemented anterior screw fixation in type II odontoid fractures in the elderly: A cadaveric study

Background ContextOdontoid process fractures are the most common injuries of the cervical spine in the elderly. Anterior screw stabilisation of type 2 odontoid process fractures improves survival and function in these patients but may be complicated by failure of fixation.PurposeTo determine whether cement augmentation of a standard anterior screw provides biomechanically superior fixation of type II odontoid fractures in comparison to a non-cemented standard screw.Study designTwenty human cadaveric C2 vertebrae from elderly donors (mean age 83 years) were obtained.
