ZygoFix has developed zLOCK, a miniature spinal stabilization system without screws.
ZygoFix has developed the zLOCK, a miniature implant that achieves spinal fusion without using screws. zLOCK utilizes the natural construction of the vertebrae to provide spinal stability, thereby eliminating the need to insert pedicle screws. Its novel implant is inserted in the segment’s facet joints located at the back of the spine and cancels inter-vertebrae motion.
The 3D printed implant is an innovative combination of rigid and flexible elements, providing the ability to withstand the load applied on the facet joint and to fit into all shapes and sizes of joint anatomy.
Due to its unique design and placement, zLOCKprovides numerous advantages:
The market seeks an improved minimally invasive solution for spinal fusion that offers minimum trauma and maximum efficacy.

Spinal fusion is a surgical procedure prescribed for severe back and leg pain due to such conditions as degenerative discs or spondylolisthesis (slipped vertebra), which cause unwanted pressure on the spinal cord or nerves. The procedure is performed by relieving the pressure and stabilizing the spine. Spinal fusion is one of the most common surgical procedures – fifth in terms of OR time consumption (HCUP Statistical Brief #186).
During the fusion procedure, part of the intervertebral disc is removed and replaced with a stabilizing implant (a “cage”). To en ensure spinal stabilization is achieved, external hardware consisting of pedicle screws and rods are used to lock the vertebrae together.
Placement of the pedicle screw construct requires six incisions (minimally invasive process) and encompasses risk of misplacement which can lead to injury or revision surgery.
The market seeks a simpler, safer, and less invasive method.
According to Orthopedic Network News Spine Report (October 2017), there are 450,000 spinal infusion procedures in the United States. Zygofix estimates its global market at $1 billion based on an estimated 40% of the (relevant) market.
