Use of McGrath videolaryngoscope during awake intubation in patients undergoing surgery for cervical spine instability

The assessment of cervical spine instability following traumatic injury is controversial [1, 4, 5, 8]. Typical definitions of cervical instability are based on the presence of several key detectable injuries using simple radiographs, computed tomography (CT), and magnetic resonance (MR) imaging. Although these imaging modalities have been shown to be relatively reliable for detection of fractures and very large soft tissue injuries, they are largely deficient for determining the presence of smaller soft tissue injuries, such as hyperstrained ligaments [1, 3]. Soft tissue injuries of this nature may be revealed with dynamic range of motion (ROM) assessment, such as a flexion and extension test with radiography. However, these tests are currently inadequate for determining the existence of specific injuries. Cervical soft tissue injuries demand further analysis, given the risk of severe and permanent neurological impairment that may accompany these injuries [2, 5].

Type Of Injury

Unilateral facet injuries are relatively common in the sub-axial cervical spine. Facet fractures, capsular disruptions, and posterior ligament tears can all contribute to this type of injury resulting in a range of instability spanning undisplaced fractures to complete unilateral dislocations [1]. For a particular injury pattern, considerable variability exists in the choice of treatment, and the modality selected is frequently based on surgeon preference [2]. This is due, in part, to a lack of biomechanical studies focused on increasing the understanding of changes in spinal stability that occur following cervical spine injury.
