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.
