Cervical degenerative index: a new quantitative radiographic scoring system for cervical spondylosis with interobserver and intraobserver reliability testing.

Ofiram E, Garvey TA, Schwender JD, Denis F, Perra JH, Transfeldt EE, Winter RB, Wroblewski JM - J Orthop Traumatol (2009)

Bottom Line: There was fair reliability between the less experienced observer and the more experienced observers.The cervical degenerative index appears to be a reliable and reproducible radiographic assessment of cervical spondylosis.The index will have direct applicability for longitudinal study of cervical spondylosis and may be clinically relevant as well.

ABSTRACT

Background: The lack of a widely available scoring system for cervical degenerative spondylosis encouraged the authors to establish and validate a systematic quantitative radiographic index.

Materials and methods: This study included intraobserver and interobserver reliability testing among three reviewers with different years of experience. Each observer independently scored four cervical radiographs of 48 patients at separate intervals, and statistical analysis of the grading was performed.

Results: There was high intraobserver and interobserver reliability between the two experienced observers. There was fair reliability between the less experienced observer and the more experienced observers.

Conclusions: The cervical degenerative index appears to be a reliable and reproducible radiographic assessment of cervical spondylosis. The index will have direct applicability for longitudinal study of cervical spondylosis and may be clinically relevant as well.

In this patient, we see the different grading scales for disc space narrowing rated by one observer as C2/3 = 0, C6/7 = 1, C4/5 = 2, C5/6 = 2, and C3/4 = 3

Fig1: In this patient, we see the different grading scales for disc space narrowing rated by one observer as C2/3 = 0, C6/7 = 1, C4/5 = 2, C5/6 = 2, and C3/4 = 3

Mentions: Each of the four factors being assessed for degenerative radiographic appearance is graded on each level, from C2-C3 through C6-C7, on a four-point scale ranging from 0 to 3. For each factor, a normal appearance yields a score of “0,” with the most severe spondylytic change yielding a score of “3.” Each factor (except sclerosis) has specific quantitative criteria as outlined in Table 1. Thus, a lower score represents a more normal-appearing radiograph, and a higher numerical value represents more degenerative spondylytic change on the radiograph (Figs. 1, 2, 3, 4).Table 1
