摘要:

背景:后纵韧带骨化症前路手术是通过直接减压,取出压迫的骨赘、骨化的后纵韧带,前路间盘从而达到彻底减压,通过置入钢板、钛网,产生前路支撑作用,有利于恢复颈椎生理曲度。但对于范围超过3个节段的患者,实施前路无法彻底切除骨化物,且减压难以维持颈椎曲度和稳定性,实施后路手术更为合适。
目的:对比分析后路椎板切除植骨内固定与前路椎体次全切除减压修复长节段颈椎后纵韧带骨化症的效果。
方法:从秦皇岛市第三医院2011年9月至2013年9月收治的长节段颈椎后纵韧带骨化症患者中选择34例进行观察,分别给予前路椎体次全切除减压(对照组)和后路椎板切除植骨内固定(观察组)治疗。所有患者治疗前均常规进行颈椎X射线、CT及MR检查,治疗后7 d进行复查。检查椎管矢状径、颈椎曲度、椎管狭窄率、骨化物分型、骨化物范围(节段)脊髓压迫率。并对患者进行日本骨科学会(JOA)评分,并计算其神经功能改善情况。
结果与结论:经影像学检查,两组患者的椎管矢状径和治疗前颈椎曲度等指标比较差异均无显著性意义(P均> 0.05),但治疗后两组颈椎曲度和脊髓压迫率差异均有显著性意义(P均< 0.05),观察组优于对照组。治疗前两组患者的JOA评分差异无显著性意义(P > 0.05),但治疗后两组的JOA评分、平均改善率以及优良率差异均有显著性意义(P均 < 0.05),观察组优于对照组。在治疗后并发症发生率方面,两组差异无显著性意义(P > 0.05)。提示与前路椎体次全切除减压治疗相比,采用后路椎板切除植骨内固定修复长节段颈椎后纵韧带骨化症可以获得良好的效果。

Abstract:

BACKGROUND: Anterior surgery for treatment of long-segmental cervical ossification of the posterior longitudinal ligament is consisted of direct decompression and removal of the compressed osteophytes and ossified posterior longitudinal ligament, anterior cervical discectomy can achieve complete decompression, plate and titanium net placement produces anterior approach support, which is conductive to restore physiological curvature of cervical vertebra. As for multi-segmental ossification (> 3), anterior surgery cannot resect the ossified tissue, the decompression cannot maintain cervical curvature and stability, so posterior approach is suggested for surgeries.
OBJECTIVE: To compare the effects of posterior laminectomy implant fixation and anterior corpectomy decompression for repair of long segmental cervical ossification of posterior longitudinal ligament.
METHODS: Thirty-four patients with long segmental cervical ossification of posterior longitudinal ligament were recruited from Qinhuangdao Municipal Third Hospital from September 2011 to September 2013, and were treated with anterior corpectomy decompression (control group) and posterior laminectomy bone grafting and internal fixation (observation group). All patients were detected by cervical X-ray, CT and MR examinations prior to treatment, and re-checked at 7 days after treatment. The vertebral canal sagittal diameter, cervical curvature, spinal stenosis rate, ossification type, ossification range (segments), and spinal compression rate were observed. JOA scores were evaluated and improvement of neurological function was assessed.
RESULTS AND CONCLUSION: The imaging examination results showed that, canal sagittal diameter and preoperative cervical curvature showed no significant difference between the two groups (P > 0.05), but cervical curvature and spinal cord compression rate in the observation group showed significant differences compared with the control group after treatment (P < 0.05). Before operation, no statistically significant differences were found in the JOA scores of the two groups (P > 0.05); after treatment, the JOA scores, improvement rate and excellent rate showed significant differences (P < 0.05), the observation group was better than the control group. There was no significant difference in postoperative complication rate between the two groups (P > 0.05). Compared with anterior corpectomy decompression, posterior laminectomy bone graft and internal fixation can obtain good effects in the treatment of long segmental cervical ossification of posterior longitudinal ligament.
