Degenerative spondylolisthesis (pseudospondylolisthesis) is a degenerative disorder of the intervertebral motion segment. It can be divided into two types: forward subluxation and backward subluxation. Forward subluxation is primarily a disease of the posterior joints and is found most commonly at L4/5. Retrolisthesis is a primary disorder of the disc space and is noted more commonly at L3/4. This paper reviews the CT findings in 150 patients with degenerative forward and backward subluxation. Proper evaluation of these disorders is extremely important because of the frequency of severe symptomatic spinal stenosis or foraminal encroachment.
退变性腰椎滑脱（假性腰椎滑脱）是椎间运动节段的一种退变性疾病。它可分为两种类型：前滑脱和后滑脱。前滑脱主要是后关节的疾病，最常见于L4/5。后滑脱是椎间盘间隙的原发性疾病，更常见于L3/4。本文回顾了150例退变性前滑脱和后滑脱患者的CT表现。由于严重症状性椎管狭窄或椎间孔受压的发生率较高，对这些疾病进行正确评估极为重要。
