A bone fusion device provides stability to bones during a bone fusion
period. The bones include, for example, the vertebrae of a spinal column.
The bone fusion device comprises one or more extendable tabs attached to
the bone fusion device by associated rotating means. The bone fusion
device is preferably inserted by using an arthroscopic surgical
procedure. During arthroscopic insertion of the device, the tabs are
pre-configured for compactness. In this compact configuration, the tabs
are preferably deposed along and/or within an exterior surface of the
bone fusion device. After the bone fusion device has been positioned
between the bones, one or more tab(s) are extended. In some embodiments,
the position of each tab relative to the bone fusion device is
adjustable. Typically, the tabs advantageously position and brace the
bone fusion device in the confined space between the bones until the
bones have fused.
