Abstract:
OBJECTIVETo explore the clinical effects of cervical posterior pedicle screw internal fixation and interbody fusion for the treatment of atlanto-axial vertebral instability fractures.
METHODSFrom July 2008 to July 2013, 21 patients with atlanto-axial vertebral instability fractures were treated with vertebral pedicle screw internal fixation and interbody fusion through posterior approach. There were 14 males and 7 females, aged from 20 to 55 years old with an average of 32 years. Lifted and guided the atlanto-axial vertebral pedicle screw to reduce atlanto-axial vertebral displacement.
RESULTSAll patients were followed up from 6 to 24 months with an average of 12.5 months. Wounds got healed without complication of infection. Clinical symptoms were relieved at 6 months after operation. According to ASIA score standard to assess at 6 months after operation, the items of motion, light touch and needle score had obviously improved, and respectively were 99.45 ±0.27, 111.09 ± 0.47,111.11 ± 0.58. VAS and NDI scores also had obviously improved, and respectively were 1.04 ± 0.38 and 12.56 ± 2.24. Imaging examinations showed internal fixation locations were good, without atlanto-axial joint instability.
CONCLUSIONCervical posterior pedicle screw internal fixation and interbody fusion can effectively restore the stability of atlanto-axial joint, reduce complication and obtain satisfactory effects.
