Abstract: A spinal implant particularly adapted for lateral expansion while disposed in the disc space between adjacent vertebrae. The implant includes a first frame member pivotally linked to a second frame member via at least one, and preferably multiple, pivoting links. The implant may be inserted into the disc space in a collapsed configuration using a lateral approach, and then expanded in the anterior-posterior direction (lateral to insertion direction) to a deployed configuration where the first and second frame members are farther apart. The implant may be expanded by holding one frame member and pushing on the other frame member or one or more proximal links linking the two frame members.

Abstract: An implant assembly for a spinal column includes at least an interbody element and an add-on element that is removably attachable to the add-on element to form an implant assembly. At least a portion of the add-on element is positionable in a space between vertebrae along with the interbody element to support the vertebrae.

Abstract: An implant for spacing apart skeletal structures. The implant includes a base, a rotatable member, and a connector. The base extends around at least a portion of the member, and the member is pivotally connected to the base by the connector. The member includes a first pair of opposing sides that have a first height that is smaller than or equal to a height of the base, and a second pair of opposing sides that have a second height larger than the base. The member is movable to a first rotational position with the first pair of opposing sides facing in the same direction as the sides of the base such that the member is shorter than or equal to the base. The member is also movable to a second rotational position with the second pair of opposing sides facing in the same direction as the sides of the base such that the member is taller than the base.

Abstract: Orthopedic medical devices for use in orthopedic procedures are provided, having in certain embodiments a first member and a second member configured to replace a disk between a first vertebra and a second vertebra. Additionally, the second member is also configured to fuse the second vertebra to at least a third vertebra. In one embodiment, the second member has a first portion that is elastic and a second portion that is substantially rigid. In other embodiments, the second member is substantially rigid. In yet another embodiment, the first member and second member are configured to replace a disk between the first vertebra and the second vertebra, and the second member and a third member are configured to replace a second disk between the third vertebra and a fourth vertebra. In this embodiment, the first, second, and third members may be connected to vertebrae by various anchors.

Abstract: The present application discloses intervertebral implants and methods of using the implants. The implants may include inferior and superior surfaces, and a sidewall that together form the body of the implant. One or both of the inferior and superior surfaces may include tapered surfaces to facilitate distraction of adjacent vertebral members. The multiple tapered sections allows insertion via multiple surgical approaches using a single implant thereby negating the need to employ a plurality of approach-specific implants as is conventional.

Abstract: The present application is directed to devices and methods to shape an intervertebral space between vertebral members. In one embodiment, the device includes a guide with an elongated shaft and an enlarged distal section. An outer member may include first and second arms that are spaced a distance apart. Teeth may be positioned on outer surfaces of one or both of the first and second arms. The outer member may be movably positioned along the guide between first and second positions. The first position may include the teeth positioned over the shaft with the first and second arms being positioned a first distance apart. The second position may include the teeth positioned over the distal section with the first and second arms being positioned an expanded second distance apart.

Abstract: Devices and methods include an anchor assembly engageable to a vertebra and a connecting element positionable through a receiver of the anchor assembly. The receiver includes chamfered surfaces along a leading end of the receiver to facilitate endwise insertion of the connecting element into the passage.

Abstract: The present application discloses intervertebral implants and methods of using the implants. The implants may include inferior and superior surfaces, and a sidewall that together form the body of the implant. An inner chamber is formed between the surfaces and the sidewall. An opening extends through the body to access the inner chamber. A cover plate is sized to extend across the opening. The cover plate is adjustable between an open position to access the inner chamber, and a closed position to prevent the bone growth material from escaping from the inner chamber.

Abstract: The present application is directed to intervertebral implants. The implants may include a body with superior and inferior surfaces, and a sidewall. An interior section may be positioned within the body and sized to contain bone growth material. An opening extends through one or both of the superior and inferior surfaces to access the interior section. A cover may be attached to the body to extend across the opening. In some embodiments, the cover includes teeth that engage a vertebral member. The cover may further include a plate that extends across the opening, and an attachment mechanism to attach the cover to the body. One method of using the implant may include inserting bone growth material into the interior section and attaching the cover to close the opening. The implant may then be inserted into the intervertebral space.

Abstract: An apparatus and procedures for percutaneous placement of surgical implants and instruments such as, for example, screws, rods, wires and plates into various body parts using image guided surgery. The invention includes an apparatus for use with a surgical navigation system, an attaching device rigidly connected to a body part, such as the spinous process of a vertebrae, with an identification superstructure rigidly but removably connected to the attaching device. This identification superstructure, for example, is a reference arc and fiducial array which accomplishes the function of identifying the location of the superstructure, and, therefore, the body part to which it is fixed, during imaging by CAT scan or MRI, and later during medical procedures.
