Abstract
The cranio-vertebral junction (CVJ) contains vital neurovascular structures, and traumatic injuries of the cranio-vertebral junction can affect these structures causing major disability including mortality. Various ligaments around CVJ play a vital role in protecting these neurovascular structures as bony anatomy around CVJ does not give good stability, hence CVJ trauma may compromise these ligaments which leads to instability. Knowledge about the biomechanics of CVJ is very crucial because CVJ has unique biomechanics. Various implants are available for osteosynthesis, occipito-cervical fusions, and atlantoaxial fixations in case of CVJ trauma. Implants around CVJ have started with wiring, hooks, loops and later occipito-cervical plates, occipito-cervical screw rod system, trans-articular screws, C1/2 Goel-Harms fixation, and C1/2 spacers have emerged. Osteosynthesis with anterior odontoid fixation has eliminated consequences of C1/C2 fusion. Salvage procedures like laminar screws and graft-clamp techniques are of great use when other fixations fail. Recent advancement in CVJ implants has changed the outcome of patients with CVJ trauma with excellent reduction and fixation capabilities. Complications like vertebral artery injury, excessive bleeding, dural injuries, neurological deficits, infection, and non-union should be kept in mind while treating CVJ trauma.
