HintergrundFrakturen des Dens axis vom Typ II stellen die häufigste Verletzung der Halswirbelsäule alter Patienten dar. Für die Entscheidung, ob ein Patient operativ oder konservativ behandelt werden sollte, enthält die Literatur nur wenig Evidenz.Material und MethodenDie Mortalität und Überlebenswahrscheinlichkeit stratifiziert nach Behandlung für...
Aims: We wished to investigate the role of the cervical ligaments in maintaining atlantoaxial stability after fracture of the odontoid process. Methods: We dissected eight fresh-frozen cadaveric cervical spines to prepare the C1 and C2 vertebrae for biomechanical analysis. The C1 and C2 blocks were mounted and biomechanical analysis was performed t...

C1 lateral mass and C2 pedicle (C1LM-C2P) fixation is a relatively new technique for atlantoaxial stabilization. Complications from C1LM-C2P fixation have been rarely reported. The authors report unilateral rod migration into the posterior fossa as a rare complication after this posterior C1-C2 stabilization technique. A 23-year-old man suffered se...
Odontoid process fractures of the axis are frequent in elderly patients. However, the impact in terms of handicap and morbidity in this particular population are unknown. The role of surgical treatment remains controversial. We present a retrospective series of patients aged 70 years or older with odontoid fractures treated in our department betwee...
