Abrishamkar S, Mahmoudkhani M, Aminmansour B, Mahabadi A, Jafari S - Adv Biomed Res (2014)

Bottom Line: Pre- and postoperative T2-weighted sagittal magnetic resonance imaging (MRI) compared for Modic and Los Angeles disk degeneration grading, then, data analysis on SPSS (version 20) software, paired t-test, and others.The result of study shows for first operation that grade (II) Los Angeles is the most common, but, for second procedure grade (IV) was less common and the mostly decreased (from 14.7 to 9.2%).Our study showed that the Los Angeles criterion is more practical and useful for prediction of recurrence and in the patients with Los Angles grade III and IV and grade II and III on Modic scale, the chance of recurrence is less than patients with lower grades.

ABSTRACT

Background: After single disk herniation operation, about 5-20% recurrences may occur. Different etiology may affect the prevalence of recurrence. Disk degeneration according to Modic and Los Angles scales could affect recurrence rate. This study wants to show the relationship between disk space degeneration according to these scales on severity, time, and prevalence of disk herniation recurrence.

Materials and methods: Thirty-four patients presented with radicular pain (with or without back pain) and history of lumbar disk surgery was included in this prospective study. Pre- and postoperative T2-weighted sagittal magnetic resonance imaging (MRI) compared for Modic and Los Angeles disk degeneration grading, then, data analysis on SPSS (version 20) software, paired t-test, and others.

Results: The result of study shows for first operation that grade (II) Los Angeles is the most common, but, for second procedure grade (IV) was less common and the mostly decreased (from 14.7 to 9.2%). In addition, Wilcoxon test shows no change of Los Angeles grading for both first and second surgery (P = 0.06). Whereas; based on Modic criteria grading was different from first operation, in other words, grade (I) (41.2%) in first operation was changed to 20.6% in second operation (P = 0.007).

Conclusion: Our study showed that the Los Angeles criterion is more practical and useful for prediction of recurrence and in the patients with Los Angles grade III and IV and grade II and III on Modic scale, the chance of recurrence is less than patients with lower grades.

Figure 7: Correlation between the disk herniation operation time and recurrence according to Modic and Los Angeles scales

Mentions: Based on the Los Angeles scales, there was association about 35% between period from the first surgery and recurrence with disk grading, and upon Spearman association test this correlation was significant (P = 0.046). Although based on Modics scales there was an association in about 24% between this period and disk grading, this correlation was not significant (P = 0.17). The correlation between period and disk grading has been shown in Figures 6 and 7.
