Axial Lumbar Interbody Fusion-A Critical Analysis

Numerous open and minimally invasive techniques have been developed but all of these approaches experience the same shortcomings related to biomechanics or inherent iatrogenic destabilization [16]. In an attempt to alleviate many of the limitations of previous lumbar fusion techniques, a pre-sacral approach to the lumbosacral junction has been investigated. The axial lumbar inter body fusion (AxiaLIF) system (TranS1, Inc. , Wilmington, NC) combines a minimally invasive technique with a novel corridor approach. A total of three patients were evaluated I this study. Results were compared preoperatively and following the surgery at 3 and 6 months. There was a significant improvement in the pain scores. The Axial lumbar interbody fusion is a feasilble procedure which will require long term studies before it can be validated as a standard technique for lumbar fusion.
