Spondylolisthesis is a hereditary anomaly of the spine, often associated with intractable pain in the back and lower extremities. The diagnosis is commonplace. Approximately 5% to 7% of the population in the United States has the anomaly. This percentage varies with country and race. In patients who seek medical aid for symptoms of low back pain, 10% will have a pars defect. Laminectomy of the entire separate neural arch and a posterior interbody fusion is a superior operation for spondylolisthesis. It is a difficult operation, requiring a high degree of technical skill, but when properly performed, it is possible to attain a more rapid recovery with a lower morbidity and higher percentage of permanent cures.
腰椎滑脱是一种脊柱的遗传性异常，常伴有背部和下肢的顽固性疼痛。诊断很常见。在美国，约5%至7%的人口有这种异常。这个百分比因国家和种族而异。在因腰痛症状寻求医疗帮助的患者中，10%会有椎弓峡部裂。对整个分离的神经弓进行椎板切除术和后路椎间融合术是治疗腰椎滑脱的一种较好的手术。这是一项难度较大的手术，需要高度的技术技巧，但如果操作得当，有可能实现更快的康复，发病率更低，永久治愈的比例更高。
