Correlation of C2 fractures and vertebral artery injury.
STUDY DESIGN Retrospective review of prospectively collected data. SUMMARY OF BACKGROUND DATA Vertebral artery injuries (VAI) occur commonly after cervical spine trauma. No study has yet examined the association between VAI and specific variants of C2 fractures. OBJECTIVE To evaluate the incidence of VAI (as defined by magnetic resonance imaging/angiography [MRI/A]) in subtypes of C2 fractu...
متن کاملBilateral Pedicle and Crossed Translaminar Screws in C2
Multiple techniques exist for the fixation of C2, including axial pedicle screws and bilateral translaminar screws. We describe a novel method of incorporating both the translaminar and pedicle screws within C2 to improve fixation to the subaxial spine in patients requiring posterior cervical instrumentation for deformity correction or instability. We report three cases of patients with cervica...
متن کاملCase Report Sudden cerebral infarction after interventional vertebral artery embolism for vertebral artery injury during removal of C1-C2 pedicle screw fixation: a case report
Vertebral artery injury (VAI) is a rare but serious complication of cervical spine surgery. Instrumented posterior surgery of the upper cervical spine places the vertebral artery at the highest risk of injury. However, VAI during removal of cervical internal fixation is really rare and unexpected. We present a case of 52-year-old male patient who suffered VAI during removal of C1-C2 pedicle scr...
متن کاملComparison between posterior lumbar fusion with pedicle screws and posterior lumbar interbody fusion with pedicle screws in adult spondylolisthesis.
The purpose of this study was to compare patients with lumbar spondylolisthesis submitted to two different surgical approaches, and evaluate the results and outcomes in both groups. In a two-year period, 60 adult patients with lumbar spondylolisthesis, both isthmic and degenerative, were submitted to surgery at the Biocor Institute, Brazil. All patients were operated on by the same surgeon (FLR...
متن کاملVariation of the groove in the axis vertebra for the vertebral artery. Implications for instrumentation.
Transarticular screws at the C1 to C2 level of the cervical spine provide rigid fixation, but there is a danger of injury to a vertebral artery. The risk is related to the technical skill of the surgeon and to variations in local anatomy. We studied the grooves for the vertebral artery in 50 dry specimens of the second cervical vertebra (C2). They were often asymmetrical, and in 11 specimens on...
