Abstract
A rod, screw, and staple assembly for use in conjunction with anterior or lateral spinal rod implant apparatus includes a screw having a vertebral body screw which has a shaft which is insertable into a vertebral bone and a head portion which includes a rod receiving channel and a radially extending flange. The vertebral body staple includes a flat portion which has a hole through it. The hole has a rim which is upwardly extending and a concave recess formed in the underside of the flat portion around the hole. The staple also includes several barbs which independently hold the staple to the bone surface to which it is to be affixed. The screw is first inserted into the vertebral bone, and then the staple is mounted over the head portion of the screw, such that the head extends above the annular rim. The rod is then inserted into the rod receiving channel and seats against the uppermost surface of the annular rim. The application of a top locking nut onto the head of the screw causes the rod to compress against the staple, the barbs of which are driven into the vertebral bone, and the staple is further compression locked to the screw.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
