title: [Application of intervertebral carbon fiber cage in degenerated lumbar disorders].
abstract: OBJECTIVE
  To evaluate the effect of intervertebral carbon fiber cages in the treatment of degenerated lumbar disorders.
  
  
  METHODS
  One hundred and twelve patients of degenerated lumbar disease were analyzed retrospectively with regard to the effect of posterior lumbar interbody fusion (PLIF) using intervertebral carbon fiber cage.
  
  
  RESULTS
  In the 112 patients, disc height was 7 mm (3 to 11 mm) on average before operation and 11.2 mm (8 - 14 mm) after operation. Cobb angle was 32 degrees (21 degrees to 42 degrees ) on average before operation and 18.9 degrees (13 degrees to 21 degrees ) after operation. After follow-up for 7.8 months (4 to 13 months) on average, all operative disc spaces showed solid arthrodesis through X-ray images. Disc height was 10.9 mm (8 - 14 mm) on average, and Cobb angle was 18.5 degrees (13 degrees to 21 degrees ) on average. During the follow-up, endplate absorbing, pseudo-articulation, cage displacement, subsidence, and breaking were not found.
  
  
  CONCLUSIONS
  Implantation of intervertebral carbon fiber cages is an effective method for the treatment of lumbar degenerative disease. Accurate indications and skilled techniques are required to avoid complication.
