This study reviews the literature concerning possible therapeutic approaches for spinal cord injury. Spinal cord injury is a disabling and irreversible condition that has high economic and social costs. There are both primary and secondary mechanisms of damage to the spinal cord. The primary lesion is the mechanical injury itself. The secondary lesion(More)
OBJECTIVES The aim of this study was to review the literature on cervical spine fractures. METHODS The literature on the diagnosis, classification, and treatment of lower and upper cervical fractures and dislocations was reviewed. RESULTS Fractures of the cervical spine may be present in polytraumatized patients and should be suspected in patients(More)
BACKGROUND There are several techniques for screw insertion in upper cervical spine surgery, and the use of the 3.5-mm screw is usually the standard. However, there is no consensus regarding the feasibility of using these screws in the pediatric population. OBJECTIVE To determine the measurement of the lamina angle, lamina and pedicle length and(More)
