The aim of this study was to evaluate the clinical outcome of the hemilaminoplasty technique for the treatment of lumbar disc herniation (LDH). Forty-three cases of single-level LDH underwent a discectomy and hemilaminoplasty procedure. The preoperative JOA score and VAS of lower back and leg pain were 10.4+/-1.3, 7.8+/-2.1, and 8.6+/-1.7, respectively. The Cobb angle of lumbar sagittal alignment was 10.1+/-2.0. Twenty-five patients who agreed to lumbar discectomy through fenestration were enrolled as the control group. The postoperative JOA score and VAS of low back and leg pain of the hemilaminoplasty group were 19.4+/-1.3, 1.4+/-0.4, and 2.1+/-0.5, respectively. The Cobb angle was 29.2+/-1.9 degrees. There was no epidural scar observed in any of the patients. The Cobb angle of the hemilaminoplasty group was higher than that of the control group (p < 0.05), while the VAS was significantly lower (p < 0.05). Hemilaminoplasty is a useful method to improve clinical outcome, prevent epidural scar, and preserve the normal alignment of lumbar spine.
本研究旨在评估半椎板成形术治疗腰椎间盘突出症（LDH）的临床疗效。43例单节段LDH患者接受了椎间盘切除术和半椎板成形术。术前日本骨科协会（JOA）评分以及下背部和腿部疼痛的视觉模拟评分（VAS）分别为10.4±1.3、7.8±2.1和8.6±1.7。腰椎矢状位排列的Cobb角为10.1±2.0。25例同意通过开窗进行腰椎间盘切除术的患者被纳入对照组。半椎板成形术组术后JOA评分以及下背部和腿部疼痛的VAS分别为19.4±1.3、1.4±0.4和2.1±0.5。Cobb角为29.2±1.9度。所有患者均未观察到硬膜外瘢痕。半椎板成形术组的Cobb角高于对照组（p<0.05），而VAS显著更低（p<0.05）。半椎板成形术是一种改善临床疗效、预防硬膜外瘢痕并保持腰椎正常排列的有效方法。
