Experimental destructive lesions were produced at autopsy in the lumbar discs of nine spines including 29 radiologically normal adult lumbar intervertebral discs. Limited transverse surgical division of the posterior longitudinal ligament and adjacent annular fibers were performed followed by, in addition, the removal of the intervertebral nucleus pulposus. Without interfering with any other major structure, radiologic evidence of hypermobility was recorded in 20 of 29 normal intervertebral segments. The patterns of movement were measured by standardized radiologic criteria. The available evidence suggests that localized damage to the region of the posterior longitudinal ligament and adjacent annulus fibrosus can produce radiologic patterns of hypermobility.
在尸检时，对9个脊柱的腰椎间盘造成实验性损伤，其中包括29个放射学表现正常的成人腰椎间盘。进行了后纵韧带和相邻纤维环的有限横向手术切开，此外还摘除了椎间盘髓核。在不干扰任何其他主要结构的情况下，29个正常椎间节段中有20个记录到了活动度过高的放射学证据。通过标准化的放射学标准测量运动模式。现有证据表明，后纵韧带和相邻纤维环区域的局部损伤可产生活动度过高的放射学模式。
