目的探讨胸椎黄韧带骨化症的诊断与手术治疗方法，分析其手术时机、手术技巧、手术效果及并发症处理。方法回顾性总结56例患者的外科治疗过程，采用胸椎管后壁切除减压及侧后方入路，术中体感诱发电位监护。结果术后55例经随访1年以上，1例随访2个月。39例，良8例，可5例，差4例。结论胸椎黄韧带骨化所致的脊髓压迫症须早期手术治疗，可根据不同情况选择胸椎管后壁切除减压及侧后方入路的次环状减压的手术方式。

Surgical treatment for ossification of ligamentum flavum

Objective To investigate the diagnosis and the surgical method of ossification of ligamentum flavum(OLF) in the thoracic spine. Methods The removal of posterior structure and/or the lateral posterior structure of the thoracic spine for decompression were performed in 56 cases of OLF. SSEps monitor was applied during the operation. Results 55 cases were followed up for more than one year and only 1 case was followed up for 2 months. 39 patients were graded as excellent, while 8 patients were good and 5 patients were fair, 4 patients were getting worse after the operation. Conclusion The diagnosis and surgery of the OLF must be carried out in time. The risk of the surgery is high. The surgery with the removal of posterior structure and/or the lateral posterior structure of the thoracic spine is proved to be effective in the treatment of OLF.
