Posterior limbus vertebra (PLV) is the retropulsion of the vertebral ring apophysis resulting from disc herniation through posterior ring physis. Large PLV can cause spinal stenosis, and small PLV can be mistaken as intraspinal disc herniation. Although the clinical presentations were similar, the surgery was quite different. We had experienced preoperative misdiagnosed cases and the surgery could not be finished. Therefore we analyzed the imaging features of PLV in 34 patients in order to prompt appropriate preoperative diagnosis and surgical planning.
后路椎弓根骨骺后突（PLV）是由于椎间盘通过后路环骺板突出而导致的椎环突骺的后突。大的 PLV 可导致椎管狭窄，而小的 PLV 可误诊为椎管内椎间盘突出。尽管临床表现相似，但手术方式却大不相同。我们曾遇到过术前误诊的病例，导致手术无法完成。因此，我们分析了 34 例 PLV 的影像学特征，以期提示术前做出正确诊断和制定合适的手术计划。
