Operative Versorgung der degenerativen Halswirbelsäule

BACKGROUND: Degenerative alterations of the cervical spine often entail disc herniations and stenoses of the spinal canal and/or neural foramen. Mediolateral or lateral compression of nerve roots causes cervical radiculopathy, which is an indication for surgery in cases of significant motor deficits or refractory pain. Median canal encroachment may result in compression of the spinal cord and cervical myelopathy. Its natural history is typically characterized by episodic deterioration, so that surgical decompression is indicated in cases of clear myelopathic signs.

OBJECTIVE: The aim of the present article is to outline the operative options for patients with cervical radiculopathy and myelopathy. Furthermore, we describe the operative complications and the outcome in these patients.

MATERIAL AND METHODS: For this manuscript a systematic PubMed search was carried out, the papers were systematically analyzed for the best evidence and this was combined with the authors' experience.

RESULTS AND CONCLUSION: Depending on the cervical pathology, the most prevalent surgical options for radiculopathy include anterior cervical discectomy and fusion (ACDF), cervical arthroplasty or posterior cervical foraminotomy. Cervical myelopathy may be decompressed by ACDF, corpectomy or posterior approaches like laminectomy plus instrumented fusion or laminoplasty. The outcome depends on the cervical pathology and the type of operation. Overall, in long-term follow-up studies the results of all surgical techniques on the cervical spine are generally considered to be very good, although specific patient characteristics are more suited for a particular approach.
