Abstract
ABSTRACT: BACKGROUND: Magnetic resonance imaging (MRI) provides a noninvasive assessment of the lumbar spine. Little is thought about the MRI characteristics of cartilaginous endplate (CEP) and CEP herniation on the ground that their normal thickness is only 0.6mm, making it hard to perceive at routine MRI examinations OBJECTIVE : To study the reliable magnetic resonance imaging findings suggested cartilage endplate herniation in lumbar spine. PATIENTS AND METHODS: This prospective study was conducted on 46 patients with low back pain in the MRI unit of Al- Imamein Alkadhmein Medical City, Baghdad, Iraq between September, 2016 and August 2017. Inclusion criteria: adult patients with lumbar disc herniation proved by MRI with surgical prove of cartilage end plates herniation. Exclusion criteria include: patients with previous back surgery, history of spinal tumor and the general contraindications to MRI. Sagittal and axial T1-weighted spino-echo image and sagittal and axial T2 weighted spine echo images were obtained. Statistical analysis using SPSS version 23, the level of significance (p value) was set as ≤ 0.05. RESULT: Forty six patients with low back pain were included in this study, the mean age of 44±9 years, 26 patients were females and 20 patients were males.The CEP herniation was detected by MRI among 52.2% of patients with back pain. There was a highly significant association between CEP and increased age of the patients, back pain radiated to both limbs, L4-5 defect site, modic changes and lumbar posterior marginal nodes (p value 0.01, 0.004, 0.02, 0.03 and <0.001 respectively). No significant differences between patients with CEP herniation and those without CEP herniation regarding posterior osteophytes, dorsal vertebral cornal defect, heterogeneous signal intensity and posterior corner and mid endplate irregularities. There was a highly significant association between lumbar posterior marginal nodes and CEP herniation (p<0.001). CONCLUSION: CEP herniation is more prevalent among advanced age and at lower lumbar level. The most common MRI signs related to CEP herniation were modic changes in mid endplate and lumbar posterior marginal nodes. .
