摘　　要：目的研究椎板间开窗术及椎板切除术治疗黄韧带骨化(OLF)致胸椎管狭窄的手术效果。方法回顾性分析32例OLF患者病例资料。22例行椎板切除术,10例行椎板间开窗术。患者术前、术后的神经功能评分使用日本整形外科协会(JOA)评分标准。结果本组病例中共83个OLF节段,其中63%位于下胸段。椎板间开窗术与椎板切除术治疗OLF引起的胸椎管狭窄均有效,2例椎板切除术后患者出现后突畸形,加重神经功能损伤,而椎板间开窗术患者未出现。结论椎板间开窗术及椎板切除术是治疗OLF引起的胸椎管狭窄的有效方法,椎板开窗术降低对脊柱稳定性的损伤。Objective To investigate the effects of interlaminar fenestration and laminectomy on thoracic stenosis caused by ossification of the ligamentum flavum （OLF）. Methods Thirty-two patients who had OLF were studied retrospectively. Twenty-two patients underwent laminectomy and 10 patients underwent interlaminar fenestration. The patients were evaluated pre- and postoperatively using the Japanese Orthopaedic Association （JOA） scale. Results In a total of 83 intervertebral disc levels, more than 63% of the ossified ligaments were at the lower thoracic spine. Laminectomy and interlaminar fenestration were both effective in treating thoracic stcnosis caused by OLF. Laminectomy increased the kyphotic deformity in two patients whereas interlaminar fenestration not. Conclusions Both interlaminar fenestration and laminectomy are effective and reliable surgical methods for treating thoracic stenosis caused by OLF, and interlaminar fenestration can minimize the surgical damage to spinal stability.
