CALIBER®-L is an expandable lateral lumbar fusion device designed to streamline insertion and optimize fit. Insertion of CALIBER®-L is performed at a contracted height to ease insertion. Controlled distraction is designed to maximize indirect decompression through disc height restoration. Continuous expansion resists migration by optimizing fit. Minimized Impaction: Preserves endplate integrity which may help reduce subsidence. Controlled Distraction: Designed to maximize indirect decompression through disc height restoration. Continuous Expansion: Helps to resist migration by optimizing fit.
