对117例13-96岁成年人尸体脊柱D11和L4椎体边缘病变的发生率、分布和组织学特征进行了研究。在< 30岁的患者中仅发现1处病变，但此后频率随年龄增加而增加。大多数患者至少有1个边缘受累。50岁它们在上缘比下缘更常见，而且在前部比后部更常见。病变与其他健康椎间盘中的瓣环局灶性撕脱或瓣环撕裂进入边缘相关。边缘病变可通过影像学上的真空现象、椎体边缘硬化伴或不伴边缘杯状缺损以及局限于一侧椎间盘的骨赘来识别。组织学表现提示创伤性病因学，并且由于已知骨骼供应有疼痛敏感神经末梢，因此病变在腰痛的一般情况下可能是重要的。
The frequency, distribution and histological characteristics of vertebral rim lesions have been studied at D11 and L4 in 117 postmortem spines in subjects aged 13-96 yr. Only 1 lesion was found in patients < 30 yr, but thereafter the frequency increased with age. At least 1 rim was affected in the majority of patients .gtoreq. 50 yr. They were found more frequently in the upper than the lower rim and they were also more common anteriorly than posteriorly. Lesions were associated with focal avulsion of the annulus in an otherwise healthy disc or with annular tears running into the rim. Rim lesions can be recognized radiographically by the presence of the vacuum phenomenon, vertebral rim sclerosis with or without a cup-shaped defect in the rim, and osteophytes confined to 1 side of the disc. The histological appearances suggest a traumatic etiology, and since bone is known to be supplied with pain sensitive nerve endings the lesions may be important in the general context of low back pain.
