Magnetic resonance imaging (MRI) is widely used in pediatric spinal disorders, but the prevalence of associated lumbar disc degeneration (DD) has not been evaluated previously. In this study we investigated whether children with suspected spinal disease had increased tendency to early DD. We analyzed lumbar MRI scans of 32 patients and 49 control subjects under 15 years old. Only four patients (13%) had DD on T2-weighted MRI and they were all over 10 years old. Eleven subjects (22%) in the control group had DD. It seems that disc degeneration is seldom found in patients under 10 years old.
磁共振成像（MRI）在儿科脊柱疾病中广泛应用，但此前尚未评估相关腰椎间盘退变（DD）的患病率。在本研究中，我们调查了疑似脊柱疾病的儿童是否有早期DD倾向增加的情况。我们分析了32例患者和49例15岁以下对照受试者的腰椎MRI扫描结果。在T2加权MRI上只有4例患者（13%）有DD，且他们均超过10岁。对照组中有11名受试者（22%）有DD。似乎10岁以下患者很少发现椎间盘退变。
