Degenerative vertebral dislocations (laterolisthesis) are responsible for progressive transverse intervertebral shift. These changes appear like a translation of the lateral edge of a vertebra compared to that of the underlying vertebra and are easily diagnosed. Vertebral dislocations can be secondary to active lumbar scoliosis or unilateral or asymmetrical degenerative spondylolisthesis. In every case, the appearance of laterolisthesis is reflected by the onset or aggravation of scoliosis which may become self-perpetuating. This lesion is secondary to osteoarthritic disruption of the integrity of the intervertebral disk and ligaments. Open and closed patterns have been described depending on the side of the associated disk opening. The onset of a rotatory dislocation reflects the progressive evolution of the deformity, which may require medical treatment, or surgical reduction and fixation by vertebral arthrodesis.
退行性椎体脱位（侧方滑脱）导致椎间横向移位逐渐加重。这些变化表现为一个椎体的外侧边缘相对于其下方椎体的外侧边缘发生平移，很容易诊断。椎体脱位可能继发于活动性腰椎侧弯或单侧或不对称的退行性椎体滑脱。在每种情况下，侧方滑脱的出现都表现为脊柱侧弯的发生或加重，而脊柱侧弯可能会自行持续发展。这种病变继发于椎间盘和韧带完整性的骨关节炎性破坏。根据相关椎间盘开口的侧别，已描述了开放型和闭合型。旋转脱位的发生反映了畸形的逐渐发展，这可能需要药物治疗，或通过椎体融合术进行手术复位和固定。
