[A comparison study of interbody cage in lumbar degenerative disease].
OBJECTIVE
To compare the advantages and disadvantages of TFC/BAK, Prospace and Brantigan I/F carbon cages and summarize their applications.


METHODS
One hundred and twelve cases of Brantigan I/F, 123 cases of TFC/BAK and 45 cases of Prospaces were used in the treatment of degenerated lumbar disorders. The clinical results and complications were observed and analyzed.


RESULTS
All devices restored the height of intervertebral space and achieved immediate stability after insertion. One hundred and twelve cases of Brantigan I/F cages were solid fused, the clinical results were satisfactory. Three cases of TFC/BAK cages subsided into the vertebra and 2 cages retropulsed slightly during follow-up. There was no serious complications of nervous system, but the operation time and amount of bleeding in Brantigan I/F group increased.


CONCLUSIONS
Carbon fiber intervertebral cages are an effective method in treating degenerated lumbar disorders. To avoid complications, the indications and techniques must be selected carefully.
