Excerpt

Our article, “Cervical Disc Protrusion Correlates with the Severity of Cervical Disc Degeneration: A cross-Sectional Study of 1,211 Relatively Healthy Volunteers,” was published in Spine 2015;40:E774–E779. There is an error in Figure 2. Specifically, the bottom labels in Figure 2, “Algorithm for the grading system and assessment of cervical disc degeneration grade using the modified Pfirrmann classification system,” should be switched (please see below revised Figure 2). Despite this labeling error, numerical data in the figure was correct and the error did not affect results and conclusions.
