Axial Lumbar Interbody Fusion AxiaLIF
TranS1 has pioneered a revolutionary approach to access the lumbar spine. The AxiaLIF (Axial Lumbar Interbody Fusion) System includes surgical instruments for creating a safe and reproducible pre-sacral access route to the L5 - S1 vertebral bodies. The AxiaLIF technique features novel instrumentation to enable standard of care fusion principles, distraction and stabilization of the anterior lumbar column, while mitigating the soft tissue trauma associated with traditional lumbar fusion through open surgical incisions.
AxiaLIF, combined with pedicle screws, provides a completely percutaneous 360-degree fusion at L5-S1.
By enhancing proven minimally invasive access techniques, the AxiaLIF system for L5-S1 spinal fusion has been developed. The AxiaLIF system includes proprietary devices used to access the spine, remove the diseased disc material, re-establish normal disc height, and stabilize the spine to enable lumbar fusion. This procedure is performed via an incision of less than 1-inch in length, with complete preservation of all native paraspinal soft tissue structures including the annulus.
- Safe, Reproducible Pre Sacral Access
- Soft Tissue Sparing
- Dynamic Decompression via distraction
- Immediate Rigid Segmental Stabilisation
- Native soft tissue spinal support structures are left intact
- Completely spares all muscle, bony, annular and soft tissue
- Minimizes blood loss, nerve and blood vessel damage
Dynamic decompression of the nerve root via distraction and instantaneous rigid fixation in one step
- Preserves all other surgical options
- Least Invasive Access
- Reduces OR time
- Reduces length of stay
May expedite the patients' post-operative recovery period, enabling them to return to work
Preliminary cadaver, animal, and human studies were performed to determine the feasibility of axial anterior lumbosacral spine access using a percutaneous, presacral approach. Custom instruments were directed under fluoroscopic guidance along the midline of the anterior sacrum to the surface of the sacral promontory where an axial bore was created into the lower lumbar vertebral bodies and discs. Imaging and gross dissection were performed in cadavers and animals. The procedure was used for lumbosacral biopsy in human subjects guided by intraoperative imaging and clinical monitoring. All procedures were technically successful. This study demonstrates the feasibility of the axial access technique to the anterior lower lumbar spine.
