|Back pain is a common problem and occurs in both young adults and older people. Cause of back pain can be varied and range from degenerative disk disease to lumbar canal stenosis. Lumbar fusion is a well-accepted treatment for recalcitrant low back pain (LBP) of mechanical origin with neural compromise not responding to conservative management. In the last decade, there has been a dramatic increase in the number of lumbar fusions performed. The lowermost two levels of lumbar spine, i.e. L4 and L5, contribute most to the motion as well as normal lordosis of lumbar spine and also most commonly degenerate at times leading to recalcitrant back pain and radicular pain. Axial lumbar interbody fusion (AxiaLIFÂ®) has been developed as a minimally invasive option for decompression and fusion at these two levels of lumbar spine (i.e. L5-S1 and L4-L5). AxiaLIFÂ® ((TranS1, Inc., Wilmington, NC) is an interbody device to be implanted through a para coccygeal approach. This device is fairly new and has been approved by FDA in 2004 for L5- S1 and in May 2008 for L4-S1 fusion to be used only with conjunction with a posterior fixation device such as pedicle screws or facet screws.
