Anterior lumbar interbody fusion with osteoinductive growth factors.
Anterior intervertebral fusion increasingly is used as a treatment for discogenic or intersegmental pathologic diseases of the lumbar spine. This is in part attributable to the evolution and refinement of laparoscopic and minimally invasive surgical techniques that now can be used to access the anterior spinal column. It also is attributable to the availability of newer generation intervertebral fixation devices such as the threaded titanium cages or threaded allograft bone dowels, both of which are technically simpler to implant. Recently, limited clinical studies of intervertebral lumbar fusion have examined the use of these devices combined with osteoinductive growth factors as substitutes for autogenous bone graft. Early clinical results of lumbar fusion using threaded intervertebral implants filled with recombinant human bone morphogenetic protein-2 have been favorable. Higher fusion rates, shorter operative times, and shorter hospital stays have been reported in the initial series. Clinical trials involving larger cohorts with various spinal applications for osteoinductive molecules currently are in progress.
