Clinical study on anterior hollow screw fixation in the treatment of traumatic atlantoaxial instability odontoid fractures

Abstract

Objective To study the effect of anterior hollow screw fixation in the treatment of traumatic atlantoaxial instability odontoid fractures .Methods 25 patients with traumatic atlantoaxial instability odontoid frac-tures who received anterior hollow screw fixation were chosen .The neck was fixed for 3 months after operation .The fracture reduction ,fixation and fracture healing ,the elimination of the head and neck clinical symptoms and postopera-tive complications were examined and compared before and after surgery .Results All 25 patients were followed up for 6 to 24 months,an average of 15 months.Odontoid fractures healed without implant loosening ,fracture,wound in-fections and other complications .6 cases of muscle weakness and numbness recovered after 3 to 4 months.Conclusion The current treatment of odontoid fractures in many ways ,but the anterior compression screw fixation in the treatment of odontoid fractures has advantages of simple operation ,reliable fixation,high healing rate,etc.,it is the first choice for this type of fracture .
