摘要: Rigid fixation of the axis with C1-2 transarticular screws or C-2 pedicle results in high fusion rates but remains technically demanding because risk injury to vertebral artery (VA) and limitations imposed by anatomical variability. Translaminar crossing bilateral provides rigid is simple, not affected variations individual anatomy, does place VA at risk. The long-term 20 patients treated translaminar for craniocervical, atlantoaxial, axial-subaxial instability are presented, 100% no neurological vascular complications. may be a good option surgeons proficient more methods stabilization.
