Abstract
Aim of the work
This study aims to evaluate the rate of success of the anterior cervical discectomy and fusion with intervertebral cages as a line of surgical intervention in the management of patients with double level cervical disc disease in relation to clinical relief of the symptoms and fusion rate.
Conclusion
A patient with cervical disc disease requires a through evaluation by a clinician. Potential sources for pain and neurological deficit must be ruled out by appropriate diagnostic imaging or electromyoraphic studies, or both. After the diagnosis has been narrowed to the pathology of the cervical spine, an appropriate treatment plan should be formulated for the patient. The degree and extent of neurological injury determine the need for conservative or surgical management. Patients with radicular symptoms may be treated conservatively, whereas patients with myelopathic symptoms need careful and expeditious management, usually requiring surgery.
The anterior cervical approach to the spine has undergone a tremendous evolution over the last 5 decades and is well accepted by the surgeons. This approach is extremely versatile, allowing the surgeon full access to all the pathologic components responsible for clinical symptoms. Foraminal distraction, spinal cord decompression, and lordotic curvature can be performed by placement of a graft and subsequent stabilization, if required. Fusion can be enhanced through meticulous preparation of the end plate, maximizing bone-to-graft contact at the interface and compression. Excellent results are usually achieved with little or acceptable morbidity.
The ideal cervical fusion technique should guarantee 100% success in terms of fusion rates and neurological recovery, avoiding surgery-related complications. Cage constructs achieve immediate segmental internal fixation while providing structural support for the bone material inside and around the cage itself, even at multiple levels.
