Our experience supports the feasibility of percutaneous vertebral augmentation in the treatment of several clinically relevant spinal instrumentation failure conditions, with excellent safety and efficacy profiles, both in avoidance of revision surgery and for pain palliation.

Through this single-center consecutive prospective study, we evaluated the results of 2 posteriors C1/ C2 constructs procedure for Type II odontoid fractures OBAV. 5 adult patients were succefully treated by Harms's technique and a novel C1 lateral mass/C2 laminar hooks procedure in posterior approach for Type II odontoid fractures OBAV.The mean follow-up was 10 months. All patients were male. The mean age was 49.2 years. Bony fusion and clinical outcome were favorables in all cases.No neural or vascular damage related to theses techniques have been observed. Surgeons might consider theses differents approachs techniques before realizing a treatment.
