Abstract:
Objetive: Evaluate clinically and radiographically whether the presence and size of dural ectasia (ED) is associated
with low back pain in patients with Marfan syndrome (MS).
Material and method: 92 patients diagnosed with MS according to Ghent criteria were studied prospectively
for one year. Underwent a medical history, imaging tests, including a lumbar spine MRI volumetric and 3
questionnaires were given: SRS 22 (Scoliosis Research Society) and SF 36 v-2 and Oswestry Disability Index
subdivided according to the sample in group I (patients with moderate lower back pain and / or severe) and
group II (patients without pain).
Results: Multivariate analysis of variables related to low back pain, the ED reached statistical significance.
ED was present in 75.9% of patients in group I, and 49.2% in group II. The presence of ED is associated with
low back pain in patients with MS with an OR of 3.24 (1.21 to 8.68) p = 0.016 and the presence of vertebral
deformity (scalloping) with an OR of 129, 83 (16.1 to 1047.74) p <0.001.
Conclusion: The presence and size of ED was significantly associated with LBP in the SM but the «scalloping»
does not affect the increased intensity of pain.Keywords:
