Peckham ME, et al. - Given that, the usage of C1–2 intrathecal puncture has steadily decreased in part because of the perceived high risk of injury to the cervical cord, researchers present a novel osseous landmark, termed as “flare point,” to aid in C1–2 intrathecal puncture, corresponding to the posterior spinal cord margin on lateral fluoroscopic views. This landmark represents the triangular “flaring” of the posterior C1 arch at its junction with the anterior arch. According to findings, using the C1 posterior arch flare point resulted in attainment of accurate approximation to the dorsal spinal cord margin on myelography. Also, safe and optimal needle positioning was enabled by targeting between the flare point and the spinolaminar line, at the mid-C1–2 interspace.
