Abstract

Coiled spinal implants for disc, vertebral body, and spinal motion segment replacement or reconstruction comprise a plurality of loops and spaces between the loops, with the loops formed of a hollow material and having a plurality of apertures or a longitudinal gap that extend(s) through the sidewalls of the loops and into the hollow center. The coiled implants include one or more balloons within the hollow center, the spaces between the coil loops, and/or within the central void that the coil surrounds. Filling the balloon expands the loops and thereby increases the height of the coil. Bone graft material or bone cement may be deployed from the apertures or gap.
