Most surgeons undertaking anterior cervical discectomy (ACD) introduce a bone graft or cage into the disc space when the decompression is complete to prevent segmental collapse and preserve cervical spine alignment. We have conducted a prospective observational cohort study to investigate the relationship between cervical spine alignment and clinical outcome in 55 patients undergoing ACD without interbody graft or cage. At 12 months, the overall alignment of the cervical spine and the presence of segmental kyphosis at the operated level were correlated with clinical outcome measured by SF 36, Neck Disability Index and visual analogue neck pain score. Loss of the overall cervical lordosis was present in 30 patients and segmental kyphosis was found in 18. Analysis of clinical outcome showed no statistical differences between patients with preserved and abnormal cervical and segmental alignment. Disturbance of cervical and segmental alignment is common in patients following cervical discectomy, but does not appear to compromise clinical outcome at 12 months.
大多数进行颈椎前路椎间盘切除术（ACD）的外科医生在减压完成后会在椎间盘间隙植入骨移植或椎间融合器，以防止节段性塌陷并保持颈椎对线。我们进行了一项前瞻性观察队列研究，以调查55例未进行椎间植骨或植入椎间融合器的ACD患者的颈椎对线与临床结果之间的关系。在12个月时，颈椎的整体对线情况以及手术节段的节段性后凸与通过SF 36、颈部残疾指数和视觉模拟颈部疼痛评分所测量的临床结果相关。30例患者存在颈椎生理前凸的丢失，18例发现有节段性后凸。临床结果分析显示，颈椎和节段对线保持正常和异常的患者之间无统计学差异。颈椎间盘切除术后患者中颈椎和节段对线紊乱很常见，但在12个月时似乎并未影响临床结果。
