Abstract

A vertebral shock absorber in the form of an elongated compressible member having two ends, one fastened to an upper vertebra, and the other fastened to a lower vertebra. The elongated member may be fastened using pedicle screws or by way of ball-and-socket joints for enhanced range of motion. In the preferred embodiment, the elongated compressible member is constructed using telescoping sleeves to create a cavity wherein there is disposed a compressible, resilient component such as a spring, elastomeric material, liquid, gel, hydrogel, or other suitable substance. The shock absorber may be combined with an intradiscal component and/or one or more plates that extends at least partially onto a vertebral endplate to facilitate lateral application.
