Posterior Fusion in Patients with Trauma, Instability, and Tumor of the Cervical Spine.

Trauma, instabilities and tumors of the cervical spine are treated with established methods of surgery. Therefore, anterior fusion is considered to be a standardized procedure for the lower cervical spine, while posterior and anterior instrumentation facilitates stabilization of the upper cervical spine. However, special situations that particularly require posterior instrumentation in traumatic lesions, tumor or other kinds of instabilities arise again and again.
