To perform an Interrater reliability study determining the agreement between an Orthopaedic team and a Radiology team on the MRI features of prolapsed uncontained cervical discs in Flexion-Distraction injuries of the cervical spine. This leads us to determine how many patients demonstrated evidence of a ‘dangerous’ disc: an uncontained disc herniating posteriorly that may be drawn into the spinal canal during closed reduction. One hundred and ten patients who had pre-reduction MRI scans managed during the last 10 years were included. Variables were chosen and defined by the senior Author and explained to both teams prior to reviewing the scans. The review was performed by each team independently and without any access to clinical information. Data collection and interpretation was designed by a statistician to reduce risk of data entry errors. Interrater reliability/agreement was determined using the Cohen Kappa value.Purpose
