[Posterior pedicle screw system and interbody fusion in the treatment of degenerative scoliosis].

OBJECTIVE
To investigate clinical results of posterior pedicle screw system and interbody fusion in the treatment of degenerative scoliosis.


METHODS
From September 1997 to June 2002, 32 cases with degenerative scoliosis were analyzed for operative effect, postoperative complication and follow-up results.


RESULTS
The average correcting ratio of scoliosis was 47.9%, and pain relief ratio 90.6%. There was one case of pseudoarthritis and one case of brain vessel embolism. After an average 15-month (6-57 months) follow-up, there was no loss of correction and height of disc spaces and there was no shift of interbody cages.


CONCLUSION
Posterior pedicle screw combined with interbody fusion is one of safe and effective treatments of degenerative scoliosis.
