腰椎棘突间撑开器Coflex的生物力学及临床应用进展

Advances in the biomechanics and clinical application of lumbar interspinous process spacer Coflex

传统的腰椎融合技术作为治疗腰椎退行性疾病的主要方式,这种技术虽然可以缓解症状,但各种术后并发症的发生日益明显,而腰椎棘突间撑开器作为一种更加微创的治疗方法可以减少相关并发症的发生。Coflex技术作为腰椎棘突间撑开器的重要代表之一,其安全性与有效性已得到了验证。Coflex技术独特的设计使其具有独特的生物力学优势,与腰椎融合技术相比,其在治疗疾病的同时,保留了手术节段的部分活动度,可以有效避免邻椎病的发生,避免了相关并发症的发生;与单纯减压技术相比,Coflex技术持续维持椎间孔及椎间隙高度,防止疾病复发。作为新兴技术,与传统的腰椎融合技术相比,Coflex技术缺乏长期的临床随访试验且同样存在并发症,严重影响了Coflex技术的推广及使用。

Traditional lumbar fusion technology is the main way to treat lumbar degenerative diseases.Although this technology can relieve symptoms,the occurrence of various postoperative complications is becoming increasingly obvious.Treatment methods can reduce the occurrence of related complications.As one of the important representatives of the lumbar interspinous process spacer,Coflex technology has been verified for its safety and effectiveness.The unique design of Coflex technology gives it have unique biomechanical advantages.Compared with lumbar fusion technology,Coflex retains part of the range of motion of the surgical segment while treating the disease,which can effectively avoid the occurrence of adjacent spondylosis and related vertebral complications.Compared with the simple decompression technique,the Coflex technique continuously maintains the height of the intervertebral foramen and the intervertebral space and prevents disease recurrence.As an emerging technology,compared with traditional lumbar fusion technology,Coflex technology lacks long-term clinical follow-up trials and has complications,which seriously affects the promotion and use of Coflex technology.
