这是一项回顾性研究。我们想要研究腰椎高强度区（HIZ）在磁共振成像（MRI）上的临床相关性以及创伤史与椎间盘破裂（IDD）的关系。一些作者认为腰椎（l -脊柱）MRI上的HIZs是IDD的可靠标志。IDD中脊柱损伤的发生率和类型尚未被仔细分析。我们回顾了737例伴有或不伴有腿痛的腰痛患者的左脊柱mri，以确定是否存在HIZs。t2加权MR图像上的HIZs根据april和Bogduk标准确定。为了进一步分析疼痛，对医疗记录进行了审查并进行了电话采访。在符合纳入标准的737例患者中，有117例患者和153个椎间盘发现HIZs。对99名患者进行了医疗记录审查和电话采访。其中，42名患者曾有过创伤发作。其中17人有相对高能量的伤害，如交通事故或跌倒。关于腰痛，27例患者主诉为典型的椎间盘源性腰痛。只有11例患者既有创伤史又有典型的椎间盘源性疼痛，41例患者（42%）既没有创伤史也没有典型的自然疼痛。考虑到椎间盘源性疼痛的发生率较低，l -脊柱MRI上的HIZ似乎没有通常认为的IDD的特异性标志物那么有意义。创伤，如交通事故，似乎不太可能是IDD的主要原因。
This is a retrospective study. We wanted to investigate the clinical relevance of the lumbar high intensity zone (HIZ) on magnetic resonance imaging (MRI) and the relationship of trauma history to internal disc disruption (IDD). HIZs on lumbar spine (L-spine) MRI have been suggested as a reliable marker of IDD by some authors. The prevalence and type of spinal trauma in IDD have not yet been carefully analyzed. L-spine MRIs of 737 patients with low back pain with or without associated leg pain were reviewed for the presence of HIZs. HIZs on T2-weighted MR images were determined according to the Aprill and Bogduk criteria. A review of medical records and a telephone interview were performed for further analyses of pain. HIZs were found in 117 patients and 153 discs among a total of 737 patients who met the inclusion criteria. Both a medical record review and a telephone interview were possible with 99 patients. Among these, 42 patients had had an episode of trauma. Seventeen of these had a relatively high-energy injury such as a traffic accident or a fall. Regarding back pain, 27 patients complained of typical discogenic back pain. Only 11 patients had both a trauma history and typical discogenic pain and 41 patients (42%) had neither a trauma history nor typical natural pain. Given the low incidence of discogenic pain, a HIZ on an L-spine MRI appears less meaningful than often assumed as a specific marker of IDD. Trauma, such as a traffic accident, seems unlikely to be the main cause of IDD.
