METHODS AND DEVICES FOR RESTRICTING FLEXION AND EXTENSION OF A SPINAL SEGMENT

摘要

Methods and devices for restricting movement of a spinal segment by providing an adjustable constraining device that includes a tether and a compliance member coupled together. The tether is coupled to a superior spinous process and an inferior spinous process or a sacrum so that the construct of the compliance member and tethers provides a force resistant to flexion and a force resistant to extension of a spinal segment. In some embodiments, the construct of the compliance member and tethers may provide only a force resistant to extension.
