Dynamic rod is used in conjunction with lumbar pedicle screw to create motion on a micrometer scale In lumbar screw –rod stabilization. This micro-movement may improve the functionality… of the patient in daily activities. Likewise, it could provide higher level of compression force to the replaced bone graft in between of vertebral bodies to promote the bone formation and ultimately fusion of the involved vertebrae

• Provides semi-rigid fixation to bridge the gap between rigid and dynamic spinal constructs

• Uses rods made of polyetheretherketone, a semi-crystalline thermoplastic polymer that meets all biocompatibility requirements
