Abstract
Abstract A spinal mobility preservation apparatus and methods are disclosed. The spinal mobility preservation apparatus may include a proximal body, an intermediate body, a distal body, and an expandable membrane. The proximal body and the distal body secure the mobility preservation apparatus to adjacent vertebral bodies. At least one of an intermediate body and an expandable membrane secure the proximal body to the distal body and provide a degree of support to a spinal motion segment defined by the adjacent vertebral bodies. A single proximal body and an expandable membrane may also compose a spinal mobility preservation apparatus. The proximal body secured to one of a superior or an inferior vertebral body and the expandable membrane extending into the intervertebral disc space to support the spinal motion segment.
