Effects of thinned cap uncovering technique on treatment for thoracic ossification of ligamentum flavum

摘要：目的 总结薄化揭盖法手术治疗胸椎黄韧带骨化症的临床效果。方法 2003年至2013年，56例胸椎黄韧带骨化症患者，其中男性40例，女性16例；年龄30～65岁(平均45岁)；平均病程3年。均经薄化揭盖法手术治疗。术后随访1～5年(平均2年零7个月)。结果 按王自立疗效评估标准，45例(约占80%)为优，9例(约占16%)为良，3例症状有所缓解未见再加重。优良率约96%。结论 薄化揭盖术是治疗胸椎黄韧带骨化症的较好选择，正确使用高速磨钻和认真应对术中出现的各种问题是手术成功的基础。
ABSTRACT: Objective To summarize the outcome of treatment for thoracic vertebra ossification of ligamentum flavum (OLF) with en-bloc removal of the spinal canal’s posterior wall termed as the ？？thinned cap uncovering？？ technique. Methods From 2003 to 2013, 56 patients with OLF were treated with thinned cap uncovering technique. In this group, there were 40 male patients and 16 female ones, with the average age of 45 years (range of 30-65 years) and the average history of 3 years. The 56 patients were followed up for an average duration of 2 years and 7 months (1-5 years). Results According to WANG’s evaluation, 45 cases (about 80%) had excellent results, 9 cases (about 16%) had good results, and 3 cases had improved symptoms, the excellence to good rates being 96%. Conclusion Removal of the posterior wall of the spinal canal via ？？thinned cap uncovering？？ technique is a reliable and effective treatment for thoracic OLF. The strategy for successful operation is to use high speed drill to cut bone accurately, which allows discectomy for thoracic vertebra and to diminish faults and complications during the surgical procedure
