Bone-sparing techniques for transforaminal lumbar interbody fusion (TLIF) are promoted to help maintain spinal stability and to minimize operative time. We present a series of seven patients who underwent TLIF with use of an interbody expandable mesh device and with supplemental instrumentation. This device is deployed and filled with bone through a small cannula. All patients experienced pain relief and suffered no complications. Our results support the data from other centers which have performed similar procedures with this device.
