Abstract
A bone plate system is provided which maintains intervertebral spacing and stability of a spine. In an embodiment, a bone plate system may include a base plate with an opening through which the fastener may be positioned to allow the fastener to be inserted into a human bone at a desired angle relative to the plate. Some embodiments of a bone plate system may include a base plate and an extender plate. An extender plate may be coupled to a base plate while the base plate is coupled to the bone.
