Distal junctional pathology remains an unsolved issue in spine surgery. Distal junctional pathology can occur on a spectrum from asymptomatic radiographic finding to catastrophic distal construct failure. It is significant to address as postoperative sagittal balance has been shown to be correlated with patient-reported outcomes. Current literature and clinical experience suggest there are techniques that can be implemented regardless of setting to avoid distal junctional pathology. Much of the avoidant strategy relies on understanding the deformity pathology, selection of the lowest instrumented vertebra (LIV), health of the segments caudal to the LIV, and methods of fixation.
脊柱外科中,交界区病变仍是一个悬而未决的问题。交界区病变的表现范围广泛,从无症状的影像学发现到灾难性的远端结构失败都有。由于术后矢状面平衡与患者报告的结果相关,因此解决这个问题很重要。目前的文献和临床经验表明,无论在何种情况下,都可以采用一些技术来避免交界区病变。许多预防策略依赖于对畸形病变的理解、最低置钉节段(LIV)的选择、LIV 以下节段的健康状况以及固定方法。
