Biomechanical comparison of anterior screw fixation in type II odontoid fracture – one- versus two-screw fixation

Sebastian Spuck, Gang Feng, Volker Tronnier, Lüder C. Busch, Arndt Peter Schulz & Robert Wendlandt
Objective: The ventral odontoid fixation in type II fractures (Anderson and D'Alonzo) by one- or two-screw- technique is a matter of debate. Two screws affords better stability for bending and rotation. Morphological studies suggested the diametrical dimensions in many patients would be insufficient[for full text, please go to the a.m. URL]
