Lumbar facet fusion has been utilized in the past for spinal stenosis and facet arthritis (using external facet screw fixation). Its success rate has been reviewed in the literature and demonstrated a high rate in obtaining fusion six months post-op.Lumbar facets endure anatomical changes throughout our life due to joint degeneration, with great variation in shape. This challenging environment makes rigid implants non-relevant for internal joint stabilization.
zLOCK’s bend-ability provides the only internal joint fixation option.With great interim clinical results from our ongoing multi-site clinical study, zLOCK lumbar fixation offers a new minimal invasive stabilization option!
The zLOCK system is based on a miniature implant that provides uncompromised stability to achieve spinal fusion. The zLOCK implant is inserted inside the joint and anchors into both bones to immobilize motion.
zLOCK’s unique construct, made from rigid titanium, adjusts its shape during implantation to accommodate the challenging synovial joint anatomy and maintains its strength to resist the joint’s applied load.
With zLOCK, the surgeon utilizes the natural construction of the vertebrae to provide spinal stability, and thereby eliminate the need to insert pedicle screws.
Due to its unique design and placement, zLOCK provides numerous advantages:
- No construct – Reducing procedural complexity and simplifying the surgery
- Less incisions – 2 incisions vs. 6 = less trauma
- Non-protruding – The implant does not protrude from the joint, eliminating/reducing tissue agitation
- Porous texture – Enabling efficient bone growth and fusion
- Flexible design – Adjusts to the patients natural anatomy
- MIS – Minimally invasive and suitable for outpatient setting
About ZygoFix
ZygoFix has developed a unique implant to achieve spinal fusion in the most minimally invasive approach and without using screws. The stabilization is achieved by inserting the implant in the spinal segment’s facet joints. Stabilizing the spinal segment via the facet joints allows to minimize the invasiveness to 1 access point instead of 3 with pedicle screws (per side, 6 for bi-lateral). ZygoFIx’s zLOCK 3D printed implant is capable of adapting its shape to the specific joint geometry as it is inserted into it. Its design locks the joint’s motion and provides the required stabilization.Website:http://www.zygofix.com
