title: Hemilaminoplasty for the treatment of lumbar disc herniation.
abstract: 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.
