As a physical barrier placed on到農 the exposed parts of operat煙音ion after laminectomy, 信麗the artificial dura is for separating 什姐from external muscle, ligament and s吃喝pinal column, and for avoiding電件 the nerve root adhesion, f喝都or preventing from complica妹生tions caused by adhe如秒sion; the material is pol東西ytetrafluoroethylene(e-PTFE), One sid什吧e is smooth surface, th制信e other side is pattern su志生rface.
clinical applicability
laminectomy is commonly perfo聽說rmed in the traditional operati匠低on treatment of prolapse of lumbar i站喝ntervertebral disc, The postop拍外erative average failur關舞e rate is 15%. Fiber adhesi遠山on of the epidural space lead to re可吃current symptoms after lum術章bar operation. It is件匠 clinically applied in surgical opera麗務tion for posterior spine.
