Tandem spinal stenosis (TSS) refers to simultaneous narrowing of noncontiguous regions of the spinal canal, typically the cervical and lumbar region. Symptomatic TSS may be present in more than 10% of patients presenting with spinal symptoms secondary to stenosis in any one region. Clinical presentation may present challenges because of a mixture of upper and lower motor neuron lesions that can confuse and mislead the clinician. Stenosis at another level may only be detected late, when there is failure to improve after treatment, and, if not detected, can result in either poor treatment outcomes or catastrophic complications. There is no uniform agreement in the management of TSS, and the reported surgical strategies include both simultaneous and staged approaches with each having positive and negative features. This article aims to provide the reader with details on the prevalence, evaluation, and guidance in treatment strategy for TSS.
串联性椎管狭窄症（TSS）是指脊柱椎管的非连续性区域同时变窄，通常发生在颈椎和腰椎区域。在因任何一个区域狭窄而出现脊柱症状的患者中，超过 10%可能存在有症状的 TSS。由于存在上运动神经元和下运动神经元病变的混合，临床表现可能具有挑战性，这可能会使临床医生感到困惑和误导。在另一个水平的狭窄可能只有在治疗后没有改善时才会被发现，如果没有被发现，可能会导致治疗效果不佳或灾难性并发症。在 TSS 的管理方面没有统一的共识，报告的手术策略包括同时和分期方法，每种方法都有其优缺点。本文旨在为读者提供有关 TSS 的患病率、评估和治疗策略方面的详细信息。
