Does Hybrid Surgery Improve Quality of Life in Multilevel Cervical Degenerative Disk Disease? Five-Year Follow-up Study.

BACKGROUND

Patient satisfaction is becoming an increasing factor worthy of consideration when evaluating the surgical quality. The correlation between patient satisfaction and surgical outcomes 5 years after cervical hybrid surgery (HS), which incorporates anterior cervical decompression and fusion and cervical disk arthroplasty techniques in multilevel cervical degenerative disk disease, has not been evaluated.

METHODS

The aim of this study was firstly to analyze prospectively collected data from a sample of patients (n = 50) treated with cervical HS for selected cases of radiculopathy and myelopathy in order to evaluate pain levels of patients, using the Neck and Arm Pain scale as an expression of visual analog scale. Secondly, we aimed to evaluate health-related quality of life, via the short-form 36, Neck Disability Index, and Japanese Orthopedic Association score. Patients were followed up for more than 5 years. Intraoperative parameters, clinical features, and outcome scores were recorded. Radiologic investigations including disk height and changes in adjacent disk spaces were assessed.

RESULTS

Clinical improvements were observed in all outcomes; significant improvements on the Neck Disability Index, visual analog scale, short-form 36, and Japanese Orthopedic Association scores were maintained at 5 years (P < 0.05). The mean disk height resulted restored in all the cases. Temporary dysphagia was rarely observed (3%). No surgery for adjacent-level disease was required. There was no significant difference in the outcomes between radiculopathy and myelopathy groups (P > 0.05).

CONCLUSIONS

HS is an effective and safe procedure for the treatment of multilevel cervical degenerative disk disease. Such a surgical construct offers postoperative improvement on pain levels and health-related quality of life.
