[Dorsal spondylodesis of the cervical spine using a hooked plate]

The hook plate is a new device for achieving dorsal fusion of the lower cervical spine (C2-T1). Using the dorsal approach, this technique guarantees independent stability that is sufficient even in cases without anterior stabilization. It satisfies the three main requirements for dorsal implants, i.e. a tension band, independent stability and the possibility of distraction. Except in cases with direct anterior compression of the neural structures (such as herniated discs) the dorsal approach allows, in most cases, direct repair of the injury or luxation. The technique and the results obtained are described and discussed.
