Impact of predominant symptom location among patients undergoing cervical spine surgery on 12-month outcomes: an analysis from the Quality Outcomes Database.



The impact of the type of pain presentation on outcomes of spine surgery remains elusive. The aim of this study was to assess the impact of predominant symptom location (predominant arm pain vs predominant neck pain vs equal neck and arm pain) on postoperative improvement in patient-reported outcomes.


The Quality Outcomes Database cervical spine module was queried for patients undergoing 1- or 2-level anterior cervical discectomy and fusion (ACDF) for degenerative spine disease.


A total of 9277 patients were included in the final analysis. Of these patients, 18.4% presented with predominant arm pain, 32.3% presented with predominant neck pain, and 49.3% presented with equal neck and arm pain. Patients with predominant neck pain were found to have higher (worse) 12-month Neck Disability Index (NDI) scores (coefficient 0.24, 95% CI 0.15-0.33; p < 0.0001). The three groups did not differ significantly in odds of return to work and achieving minimal clinically important difference in NDI score at the 12-month follow-up.


Analysis from a national spine registry showed significantly lower odds of patient satisfaction and worse NDI score at 1 year after surgery for patients with predominant neck pain when compared with patients with predominant arm pain and those with equal neck and arm pain after 1- or 2-level ACDF. With regard to return to work, all three groups (arm pain, neck pain, and equal arm and neck pain) were found to be similar after multivariable analysis. The authors' results suggest that predominant pain location, especially predominant neck pain, might be a significant determinant of improvement in functional outcomes and patient satisfaction after ACDF for degenerative spine disease. In addition to confirmation of the common experience that patients with predominant neck pain have worse outcomes, the authors' findings provide potential targets for improvement in patient management for these specific populations.

Professor of Orthopaedic Surgery

I have more than 25 years of experience treating patients of all ages with spinal disorders. I have had an interest in the management of spinal disorders since starting my medical education. I performed residencies in both orthopaedic surgery and neurosurgery to gain a comprehensive understanding of the entire range of spinal disorders. My goal has been to find innovative ways to manage the range of spinal conditions, straightforward to complex. I have a focus on managing patients with complex spinal disorders. My patient evaluation and management philosophy is to provide engaged, compassionate care that focuses on providing the simplest and least aggressive treatment option for a particular condition. In many cases, non-operative treatment options exist to improve a patient’s symptoms. I have been actively engaged in clinical research to find the best ways to manage spinal disorders in order to achieve better results with fewer complications.
