Biomechanical comparison of two different compression screws for the treatment of odontoid fractures in human dens axis specimen.

Screw with sleeve nut achieves greater fragment compression and is more robust to screw stripping compared to classic compression screw. Whether the better biomechanical properties lead to a reduction of pseudoarthrosis has to be proven in clinical studies.
