目的采用后路椎板减压双Ｌｕｑｕｅ氏棒节段固定术治疗转移性胸腰椎肿瘤。方法从１９８７～１９９４年对３２例脊柱不稳所致的严重腰背痛及２４例神经麻痹瘫痪者进行了手术治疗。结果术后３０例脊柱获得稳定，９１％病人疼痛能缓解，２４例麻痹瘫痪病人中５８％得到至少Ｆｒａｎｋｅｌ１级以上功能恢复。本组平均存活８．７月。结论手术仅限于神经功能部分改善、缓解疼痛，提高存活期内生活质量和方便护理。术后存活时间仍取决于肿瘤性质。 Objective To treat metastatic thoracic and lumbar vertebrae with posterior lumbar decompression and double Luque’s rod fixation. METHODS: From 1987 to 1994, 32 cases of severe low back pain due to spine instability and 24 cases of nerve palsy were treated surgically. Results The spine was stable in 30 patients after surgery, pain was relieved in 91% of the patients, and 58% of 24 patients with paralysis had functional recovery above Frankel level 1. The group survived an average of 8.7 months. Conclusions Surgery is limited to partial improvement of nerve function, pain relief, improved quality of life during survival, and convenient care. The survival time after surgery still depends on the nature of the tumor.
