Tramatic Odontoid Fracture Clinical Trial
Official title:
Surgical Outcome of Type II Odontoid Fracture, Harms Technique
Cervical trauma is a common cause of disability following spinal cord injury, especially in
athletic populations. The biomechanics in the atlantoaxial joint carry more than 50% of the
rotational movement which can be affected in transverse ligament tear associated with
odontoid fracture type II. Odontoid fracture type II considered an unstable fracture with a
high rate of non-union in conservative treatment. Limitation of the odontoid screws in some
cases gives the chance of posterior cervical fixation to have the superior role. Use of
polyaxial screws in Harms technique gives the best results in maintaining the majority of the
biomechanics.
Purpose: our aim in this study to evaluate Harms technique in those patients regarding pain
improvement and restoration of the motor power and to report the complications.
Study design: A retrospective case series study. We Used the Frankel grading system to
evaluate the postoperative neurological state.
After approval of Research Ethics Committee, twelve patients with post-traumatic odontoid fracture type II were scheduled in our Neurosurgery department at Sohag University Hospital for atlantoaxial fusion using polyaxial C1 lateral mass and C2 pedicle screws between January 2015 and January 2018. ;
