Abstract
Objectives. Trauma to the cervical spine can give rise to injuries that can be difficult to diagnose. This is especially valid for injuries to ligaments and joint capsules in the cranio-cervical joint complex (CCJ). The aim of the study was to see the relation between findings at surgery in the CCJ area and what was described in reports from functional Magnetic Resonance Imaging (fMRI).
Material and Methods. The findings from nine patients exposed to neck trauma and showing chronic symptoms were compared. The fMRI and surgery were performed a median time of 11 years (3-14) after the accident.
Interventions. Not applicable.
Results. All nine patients showed pronounced instability C1-C2 at surgery as well as at fMRI. Paradoxical mobility as a sign of alar ligament injury was seen in nine cases at fMRI and in eight cases at surgery. At fMRI scar formation in the joint capsule of C1-C2 was reported in nine cases and in six cases at surgery.
Discussion and Summary. Earlier radiological examinations including X-ray, MRI and CT were normal in all patients. The fMRI gave very precise information on injuries and functional disturbances that can be seen in trauma to the CCJ. The method consequently constitutes a valuable contribution to diagnosing injuries in the CCJ area.
