We have conducted a prospective study to investigate the relationship between cervical spine alignment and clinical outcome in 102 patients undergoing anterior contralateral microdiskectomy without interbody graft or cage.
Preoperative and postoperative lateral cervical radiographs were obtained, and curvature of the surgically treated spinal segments and the overall curvature of the cervical spine were evaluated in all patients. Clinical outcomes were assessed using the NDI and SF-36.
There was no significant change in the mean overall cervical curvature (C2-C7) angles postoperatively in late follow-up findings (P = .72). It represented a statistically significant mean loss of 2.73 degrees of segmental lordosis (P < .0001). The NDI scores decreased significantly in both early and late follow-up evaluations, and the SF-36 scores demonstrated significant improvement in late follow-up results in our series. Analysis of clinical outcome showed no statistical differences between patients with segmental lordosis or kyphosis.
Despite the kyphosis seen at the treated levels, the overall alignment between C2 and C7 did not change significantly, indicating that the untreated segments of the cervical spine were compensating for focal kyphosis.
我们进行了一项前瞻性研究，以调查102例行前路对侧显微椎间盘切除术且未进行椎间植骨或置入椎间融合器的患者颈椎排列与临床结局之间的关系。
获取所有患者术前和术后的颈椎侧位X线片，评估手术治疗节段的曲度以及颈椎的整体曲度。使用颈部功能障碍指数（NDI）和简明健康状况调查量表（SF-36）评估临床结局。
在晚期随访结果中，术后平均颈椎整体曲度（C2-C7）角度无显著变化（P = 0.72）。节段性前凸平均丢失2.73度，具有统计学意义（P < 0.0001）。在早期和晚期随访评估中，NDI评分均显著降低，在我们的系列研究中，SF-36评分在晚期随访结果中显示出显著改善。临床结局分析显示，节段性前凸或后凸患者之间无统计学差异。
尽管在治疗节段出现了后凸，但C2和C7之间的整体排列没有显著变化，这表明颈椎未治疗节段在代偿局部后凸。
