Abstract: A tubular retractor securement frame is disclosed including a mounting bracket, two flexor arms, and a device emplacement oriented to receive and hold in-place a surgical tool. The mounting bracket includes an elastically deformable plate, rails extending about orthogonal from the elastically deformable plate and about parallel to one another, and receptacles facing one another in the rails which are arranged to receive a retractor arm extending from a tubular retractor at a fixed angle. The flexor arms extend from the mounting bracket adjacent to the rails. The flexor arms are positioned so as not to occlude visualization through the tubular retractor and such that applying pressure to flex the flexor arms toward one another shifts the rails to accept or remove the retractor arm into or from the receptacles, and releasing the pressure reverts the rails so as to inhibit the retractor arm from being inserted or removed.

Abstract: Various spinal implants and methods for stabilizing the spine are provided. In one exemplary embodiment, a spinal implant is provided having an expandable container with an interior volume that is selectively expandable between a compressed condition and an expanded condition. The expandable container is coupled to a superior endplate member having a bone-contacting surface and an engagement surface effective to mate with a superior surface of the expandable container, and an inferior endplate member having a bone-contacting surface and an engagement surface effective to mate with an inferior surface of the expandable container.

Abstract: A tulip assembly for use in a pedicle screw system is described. The tulip assembly comprises a ring and a body. A distal end of the body comprises a first and a second reduction channel located on a first and a second side, respectively. A ramp down portion is located between the reduction channel and a securement portion. The securement portions are located distally from the reduction channels. When the tulip assembly is rotated to an open position, the reduction channels receive pins located on a distal end of the ring. Upon applying an axial downward force to a rod within the assembly and rotating the assembly to a closed position, the pins are received and secured by the securement portions. Threads located on an exterior of the body engage threads on an interior of the ring and serve as a locking mechanism to secure the rod in place.

Abstract: A surgical instrument includes a first member including an inner surface. A second member is movable relative to the first member and defines a first opening for disposal of a first implant support.

Abstract: A modular screw includes a first assembly and a second assembly. The first assembly includes a base portion having a head portion, a securing portion defining a first bore, and a receiving portion defining a second bore. The second assembly includes a first post, a second post including an engaging portion, and an elongate screw threadably engageable with the second post. The second post is dimensioned to be received through the second bore of the receiving portion of the first assembly such that when a first set screw is received in the first bore, the first set screw secures the base portion of the first assembly to the second post. The elongate screw received in the second post causes radial expansion of the engaging portion of the second post, which, in turn, causes the engaging portion to be affixed to the cavity of the first post.
