Objective  To evaluate the effectiveness, safety, cost and optimal dosing regimen of bone morphogenetic protein (BMP) used in the lumbar spine arthrodesis.
Methods  We formulated the clinical questions according to the PICO principle. We searched the ACP Journal Club (1991 to February 2008), The Cochrane Library (Issue 4, 2007) and PubMed (1990 to February 2008) as well as other relevant databases. The evidence retrieved was critically appraised.
Results  Current evidence showed that BMP was a satisfactory and safe behavior in lumbar arthrodesis. Its cost was equal to that of autogenous iliac bone graft. The types of BMP currently used in clinical practice are BMP-2 and BMP-7. Finished product of fixed composition ratio was recommended in anterior lumbar inter-body fusion, while in posterolateral fusion, 20mg of BMP-2 or 3.5mg of BMP-7 for each side was recommended, with proper carrier according to the place where it was used.
Conclusion  BMP may be introduced to China for lumbar spine arthrodesis. Before it is applied extensively, further large-scale, high-quality randomized controlled trials are needed. Meanwhile, more research is necessary to determine the proper dosage and preparation form for the dominant Chinese population.
