====== C2 screws ======

===== Options =====

1. [[C2 pedicle screw placement]] (pars interarticularis screws): directed medially.

2. [[lateral mass screw]]s: directed laterally. Length is sized to fall short of foramen transversarium

3. [[C1–2 transarticular screw]]s: associated with more risk of VA injury

4. [[translaminar screw]]s: 1 year stability appears to be less than C2 pedicle screws when used for
subaxial fusions, but was ≈ as effective for axial fusions (C1–2 or C1–3). May be useful as a “bail- out” for subaxial fusions when the C2 pars diameter is too small for pedicle screws.
