Objective To review and analyse the curative effect for lumbar fusion to treat degenerative lumbar disease.

Transforaminal lumbar interbody fusion(TLIF)is a novel lumbar fusion technique in recent years,and with the progress of minimally invasive spinal surgery,minimally invasive TLIF(mini-TLIF)technique has also got access to rapid development,which has more advantages compared with traditional open TLIF.

Conclusion In the lumbar fusion operation,the outcome of interbody fusion with spinous process is surely well,can effectualy maintain the interveterbral space hight,is a good interbody fusion choice.

Objective: To investigate the endogenous BMP-2 gene expression and the microstructure of fusion masses taken from the rabbits undergone posterolateral lumbar spinal fusion with rhBMP-2/allograft composite, autograft and allograft.

Objective: To establish finite-element models of the lumbar spinal fusion of double(L3-5、L4-S1) and single(L4-5) segments with posterior decompression and internal fixation and analyze the stress of lumbar facet joints in all kinds of loading.

Objective To evaluate the early clinical result of the lumbar single-level fusion with CC cage and follow-up clinical effectiveness in 22 patients with chronic low back pain.

[Objective]To analyze the causes of back pain in lumbar spinal stenosis and to investigate the therapeutic effect of posterior lumbar interbody fusion(PLIF)for lumbar stenosis with severe back pain.
