Abstract:

BACKGROUND: Artificial tiger bone is a kind of tiger bone biomimetic drug, which is consistent with natural bone composition and pharmacological effects. It can effectively relieve pain and strengthen bones and muscles, which can also relieve back pain caused by osteoporosis.
OBJECTIVE: To investigate the therapeutic effect of artificial tiger bone in patients with degenerative lumbar spondylolisthesis undergoing internal fixation and interbody fusion procedure.
METHODS: Sixty cases of degenerative lumbar spondylolisthesis undergoing internal fixation and interbody fusion were randomly divided into two groups and treated with artificial tiger bone plus D-calfor (treatment group) or D-calfor alone (control group). Visual Analogue Scale, and Oswestry disability index at baseline, 7 days, 1, 6 and 12 months after treatment, and interbody fusion rate at 12 months after treatment were compared.
RESULTS AND CONCLUSION: All patients underwent internal fixation and interbody fusion procedure successfully and then treated with different drugs. No significant differences were observed in the two groups regarding the Visual Analogue Scale and Oswestry disability index scores at baseline. At 6 and 12 months after treatment, the scores in the treatment group were significantly superior to those in the control group (P < 0.05). Regarding the interbody fusion rate, the treatment group was slightly better than the control group (P > 0.05). To conclude, for patients with degenerative lumbar spondylolisthesis undergoing internal fixation and interbody fusion procedure, artificial tiger bone can alleviate pain and improve dysfunction, but cannot significantly increase interbody fusion rate.
