Coflex植入系统在退变性腰椎管狭窄症中的应用

药物及物理治疗退变性腰椎管狭窄症效果不明显，但椎板切除减压等手术创伤较大，患者难以接受。德国GENERAL CARE医疗技术公司根据神经源性间歇性跛行患者症状随着腰椎后伸时加重，屈曲时缓解这一特点，设计了一种动态棘突间植入物-Coflex系统，这是一种非融合性植入物。Coflex植入系统是一种治疗腰椎管狭窄症和腰椎不稳微创治疗方法，该棘突间装置稳定了术中因减压术后引起的椎体不稳，可预防远期产生的不稳。Coflex植入系统的临床应用前景广阔,为退变性腰椎管狭窄症患者提供了一种安全有效的治疗方法。

Coflex system in treating degenerative lumbar spinal stenosis

Medication and physical therapy exhibit minimal efficacy in treating degenerative lumbar spinal stenosis. Laminectomy for compression has great trauma, which is no accepted by the patients. According to symptom changes of patients with nerve-derived intermittent claudication, i.e. aggravated with lumbar extension and relieved with flexion, Coflex system, a kind of dynamic spinous process implants, was designed by GENERAL CARE, Germany. It is non-fusion implant. Coflex system is a minimally invasive method, used to treat lumbar spinal stenosis and lumbar instability. The intrer-spinous device stabilizes the compression-induced lumbar instability and prevents the instability after a long period of time. Coflex system is a promising implantation system for clinical application, which provides a safe and effective therapy for degenerative lumbar spinal stenosis.
