极外侧椎问融合术微创治疗退变性脊柱侧凸

目的 介绍侧方人路极外侧椎间融合术微创治疗退变性脊柱侧凸的方法、技术要点,评估其临床价值.方法 采用极外侧椎间融合术微创治疗退变性脊柱侧凸8例,3例椎间融合器矫形加椎体螺钉内固定,5例单纯椎间融合器矫形.分析其临床效果、侧弯矫正率和并发症.结果 手术顺利,术中出血每例平均50 ml,术后腰腿痛明显减轻,下肢神经源性间歇性跛行缓解,侧弯矫正率为64%.随访6～30个月椎间隙高度无丢失,融合器无移位,2例有矫形角度的轻度丢失.无术中和术后并发症.结论 侧方入路的前面无注释微创治疗退变性脊柱侧凸是一种创伤小、出血少、恢复快和安全有效的方法.

Extreme lateral interbody fusion for degenerative scofiosis

Objective To introduce extreme lateral interbody fusion (XLIF) as a new minimally inva-sire spinal surgery with established correction and fusion methods to assess its clinic use for degenerative scoliosis. It is emphasized the value and highlight of this technique in spinal surgery. Methods Surgical treatment of 8 patients with degenerative scoliosis were performed with XLIF between March 2006 and April 2008. In this group of patients, 5 cases provided an anterior cage in every disc space, and another 3 supplemented with vertebrae screw fixation. Blood loss was 50 ml every procedure. To observe the low back pain, corrective rate, achieving a balanced and complications. Results The low back pain have been relieved in all patienta after operations, the disc height can be restored, allowing more room at the foraminal level for nerve roots, and lumber lordosis can be maintained. Corrective rate was 64%, there wasn't neurologic and vascular injury, 2 case had correction loss a little postoperation 6-30 month. Conclusion The potential benefits of XLIF include safe, effective, less approach-related blood loss, improved cosmetic result with smaller incisions, and reduced hospital stay for degenerative scoliosis.
