Zusammenfassung: | OBJECTIVE: To evaluate the relationship of sex and age with Modic and Pfirrmann classifications and verify the relationship between the two classifications in the group of patients studied. METHODS: 300 magnetic resonance scans (MRI) of the lumbar segment of the patients were evaluated; each lumbar segment (L1-L2, L2-L3, L3-L4, L4-L5 and L5-S1) was assessed according to Modic and Pfirrmann classifications. RESULTS: The type III of Pfirrmann was the most prevalent, whereas Modic was absent on most levels analyzed. The Modic signal was present mainly in the lower levels (L4-L5 and L5-S1) and in females. CONCLUSION: There is a strong correlation between the changes of the endplate and intervertebral discs, evidenced by changes in MRI. The relationship between Pfirrmann and Modic classifications is statistically higher the greater the disc degeneration.
OBJETIVO: Evaluar la relación del sexo y edad con las clasificaciones de Modic y Pfirrmann y verificar la relación entre las dos clasificaciones en el grupo de pacientes analizados. MÉTODOS: Fueron evaluadas 300 resonancias magnéticas (RM) del segmento lumbar de los pacientes; cada segmento lumbar (L1-L2, L2-L3, L3-L4, L4-L5 y L5-S1) fue evaluado de acuerdo con las clasificaciones de Modic y de Pfirrmann. RESULTADOS: El tipo III de Pfirrmann fue el más prevalente, mientras que el Modic estaba ausente en la mayoría de los niveles analizados. La señal de Modic estuvo presente, principalmente, en los niveles más inferiores (L4-L5 y L5-S1) y en el sexo femenino. CONCLUSIÓN: Existe una fuerte correlación entre las alteraciones de la placa terminal y de los discos intervertebrales, evidenciadas por las alteraciones en la RM. La relación entre las clasificaciones de Pfirrmann y Modic es estadísticamente mayor cuanto mayor sea la degeneración discal.
