Abstract:
[Objective]To evaluate the effects of clinical application of B-twin and cage for treatment of lumbar degenetative disease. [Methods]From June 2004 to December 2007,a total of 112 patients with lumbar degenetative disease who underwent posterior lumbar interbody fusion(PLIF) with cage and 79 patients who underwent PLIF with B-twin were enrolled. Sixty patients were selected and randomly divided into two groups(30 in each group). The clinical curative effect, the rate of bone graft fusion, the intervertebral space height and complications in both groups were analyzed and compared.[Results]In the B-twin group, the treatment was a minimally invasive technique, which offered a satisfactory effect with good bone graft fusion, fewer complications and sooner recovery, but the cost was higher than that in cage group. The cage treatment was an open sugery for fenestration operation. It had more complications but more sufficient decompression and lower cost. The rates of bone graft fusion between the 2 groups were not different in statistics.[Conclusion]The B-twin and cage techniques are two treatmens for interbody fusion of lumbar degenetative disease. Both have advantages and clinical application value. It should be choosen according to different specific conditions in the clinical practice.
