Appl. No.:

13/789972

Inventors:

Joel Torretti - State College PA, US

International Classification:

A61B 17/70
A61B 17/88

US Classification:

606278, 606279

Abstract:

A locking pedicle screw assembly has been designed which avoids misalignment and locks into place once the cap is fully threaded into the tulip, avoiding over tightening or stripping of the threads. The locking cap includes a retaining or locking ring, positioned either at the bottom of the cap so that it locks into a groove at the bottom of the threads in the tulip or at the top of the threads in the cap, locking into a groove at the top of the tulip when the cap is fully seated. In one embodiment, an audible signal is generated when the cap locks. In another embodiment, the cap is secured to a swiveling saddle that locks the rod into place as the screw cap is tightening, but does not interfere with the locking mechanism.

Abstract:

Low-profile reverse cage intervertebral implants are provided having an endplate positioned on the posterior side of the cage. Having the endplate positioned posteriorly provides several advantages including placement of fastening means away from blood vessels anterior to the intervertebral region as well as placement of bone screws to prevent backing out. The endplates are overall smaller than corresponding endplates for traditional (anterior) positioning. Implants are provided having various means for securing the implant in the intervertebral space, including one or more blades and/or one or more bone screws.
