摘要:

背景:腰椎融合是治疗腰椎滑脱、腰椎管狭窄或伴畸形的常规有效措施。目前双侧椎弓根螺钉置入内固定是公认为处理各类脊柱疾病的标准方案,其具有生物力学及临床优势。
目的:从影像学角度评估双侧椎弓根螺钉置入内固定修复腰椎间盘突出症恢复椎间高度的效果。
方法:回顾性分析42例腰椎间盘突出症患者的临床资料,均采用双侧椎弓根螺钉置入内固定治疗。螺钉置入前、置入后即刻及置入后1个月分别进行疼痛评估(下腰痛日本骨科协会评分、目测类比评分)。随访时影像学检查常规X射线摄片(包括腰椎正侧位片)及MRI,并采用CT验证螺钉置入及并发症发生情况。
结果与结论:42例患者均获得随访,随访时间3-6个月。与螺钉置入前比较,置入后即刻JOA评分和目测类比评分均有显著改善(P < 0.01);但置入后1个月与置入后即刻JOA评分差异无显著性意义(P > 0.05)。置入后即刻及置入后1个月时椎间盘高度均显著高于置入前(P < 0.01)。全部病例固定后症状均减轻,生活质量提高,1个月后X射线及CT提示内固定螺钉无松动、断裂、移位,椎间高度恢复较好。全部患者均未见不良事件发生。提示双侧椎弓根螺钉置入内固定修复腰椎间盘突出症可有效恢复椎间高度,改善临床症状,具有生物力学及临床优势。

Abstract:

BACKGROUND: Lumbar fusion is a conventional effective measure to treat spondylolisthesis, spinal stenosis or with deformity. Bilateral pedicle screw fixation is recognized as the standard treatment for various spinal disorders, and has biomechanical and clinical advantages.
OBJECTIVE: To evaluate the effects of bilateral pedicle screw fixation in the repair of lumbar disc herniation to restore disc height from the angle of imaging.
METHODS: Clinical data of 42 patients with lumbar disc herniation were retrospectively analyzed. They all received bilateral pedicle screw fixation. Pain was evaluated before implantation, immediately and 1 month after implantation using Japanese Orthopaedic Association score of lower back pain and visual analog scale score. X-ray including anteriorposterior and lateral films of lumbar spine and MRI were used. CT was utilized to verify screw placement conditions and complications.
RESULTS AND CONCLUSION: A total of 42 patients were followed up for 3-6 months. Compared with pre-implantation, Japanese Orthopaedic Association score and visual analog scale score were significantly improved immediately after implantation (P < 0.01). There was no significant difference in Japanese Orthopaedic Association score between 1 month and immediately after implantation (P > 0.05). The height of intervertebral 
discs was significantly higher immediately and 1 month after implantation than pre-implantation (P < 0.01). The symptoms were lessened after fixation in all cases, and their qualities of life elevated. At 1 month, X-ray films and CT images revealed that no screw loosening, breakage or displacement occurred. The height of intervertebral discs was perfectly restored. No adverse events appeared in patients. These data indicate that bilateral pedicle screw fixation for lumbar intervertebral disc herniation can effectively restore the height of intervertebral discs, improve clinical symptoms and have biological and clinical superiority.
