Background context Posterior atlantoaxial fixation is an effective treatment for atlantoaxial
instability. Great advancements on posterior atlantoaxial fixation techniques have been …

OBJECTIVE: We review our experience with the use of the plate and screw method of
fixation in the treatment of 160 patients with atlantoaxial instability during a 14-year period at …

Abstract INSTABILITY OF THE atlantoaxial complex may result from inflammatory, traumatic,
congenital, neoplastic, or degenerative disorders and often requires surgical stabilization …

Rigid screw fixation of the axis, for either atlantoaxial fixation or for incorporation of C2 into
subaxial cervical constructs, provides significant stability and excellent long-term fusion …

Methods. Fifty consecutive patients underwent standard CT of the cervical spine. Pedicle
and transarticular screw trajectories were plotted, and the maximum safe diameter for screw …

OBJECTIVE: We performed a biomechanical comparison of several C1 to C2 fixation
techniques including crossed laminar (intralaminar) screw fixation, anterior C1 to C2 …

Study Design. Prospective clinical trial of the screw insertion method for posterior C1-C2
fixation utilizing the patient-specific screw guide template technique. Objective. To evaluate …

The aim of this study is to evaluate the first results of the atlantoaxial fixation using polyaxial
screw–rod system. Twenty-eight patients followed-up 12–29 months (average 17.1 months) …

Study Design. Anatomic bony measurements were manually performed on 50 dry
atlantoaxial vertebral complexes with an electronic digital caliper, and a reliable landmark …

Study Design. An anatomic surface osteometric analysis of cadaveric cervical spines.
Objective. To assess the feasibility of placing a 3.5-mm cortical screw in the lateral mass of …
