The role of cervical pedicle screw in cervical spine trauma: A single-center retrospective study.

Placement of pedicle screw in the subaxial cervical spine is a challenging and complex technique but provides significant biomechanical advantages. Despite its potential complications, the role and use of cervical pedicle screw (CPS) are growing. A literature review of the significant articles on applying pedicle screws in the subaxial cervical spine was done (articles between 1994 and 2020). Furthermore, our center´s experience of 15 years related to CPS is also discussed in this study. Transpedicular instrumentation in the subaxial cervical spine requires profound anatomical knowledge and meticulous surgical technique. This technique provides superior biomechanical stability compared to the other cervical fixation techniques. Pull-out strength of CPS is twice as compared to the lateral mass screws. There have been numerous variations in the technique of CPS, varying from open techniques to minimally invasive and the use of biomodels and templates during this procedure. Clinically, CPS can be used in different cervical trauma situations, such as fracture-dislocations, floating lateral mass, and fractures associated with ankylosing spondylitis. Despite the possibility of neurovascular injury due to the proximity of the vertebral artery, spinal cord, and spinal nerves to the cervical pedicles, scientific literature, and our center × s experience show low risk, and this technique can be performed safely. CPS placement is a safe procedure, and it has great potential in the management of cervical spine trauma.
