Fused Cervical Vertebrae: A Case Series

Abstract

Vertebral fusion is the fusion of bodies and the various elements of the vertebral arch of adjacent vertebrae. Such vertebral fusion usually is seen in cervical and lumbar region, more so between the second and third cervical vertebrae, usually asymptomatic; but may also result in features suggestive of neurological compression and might also present difficulty in procedures like endotracheal intubation. This present case series involving three cases discusses the presentations and possible consequences of such vertebral fusions. The three Fused Cervical Vertebrae (FCV) studied were all different with respect to the degree and site of fusion. With respect to fusion of vertebral bodies, complete fusion was seen in two specimens and the other had only partial fusion. This series aimed at documenting the varied spectrum of vertebral fusions and the need for earlier detection so as to avoid the anticipated age related complications like degeneration of adjacent segments and neurological deficits. The observations made in this series and the comparative analysis with other articles show that the mode of vertebral fusions are very different in each specimen and thus their clinical presentations might also vary across numerous signs and symptoms for each individual and hence cannot be generalised.
