A Least-Invasive Treatment for Lumbar Fusion Disorders

PrimaLOK™SP is a next generation posterior lumbar spinous process fixation device, which uniquely compliments VariLift®LX when patient anatomy requires additional stability.

PolyAxial Design for Optimal Fit to Patient

Each foot allows +/- 15 degrees of angulation, allowing the implant to find the most stable anchoring orientation on the spinous process, and with a total of 45 degrees of angulation, primaLOK™SP maximizes contact with patient anatomy.
