Clinical Trial Summary

The zLOCK Facet Stabilization System is a fixation device intended to provide posterior stability in the lumbar spine fusion procedure. The system can be placed either as an adjunct to an inter-vertebral anterior cage or as stand-alone with/ without additional decompression of the dural sac or nerve roots as appropriate for the specific patient and surgeon's discretion. The zLOCK implant is placed inside the facet to stabilize the motion and enhance the bony fusion of the joint. The zLOCK Facet Stabilization System is intended for single-level stabilization of a spinal motion segment in order to promote bony fusion of the joint. The zLOCK system is indicated for use from L1-L2 to L5-S1 joints. The zLOCK implant is inserted into the facet joint space while adapting to the joint's changing geometry. Stabilization is achieved by a firm grip of each joint bone and resisting any relative motion. The zLOCK implant is placed percutaneously and requires only one incision per side, thereby reducing the invasiveness procedure duration and shortening the recovery period. This pivotal study was designed in order to assess the safety and effectiveness of the zLOCK system.
