An intervertebral spacer may include a superior surface configured to engage a superior vertebral body, an inferior surface configured to engage an inferior vertebral body, and a peripheral wall extending from the superior surface to the inferior surface. A proximal end of the peripheral wall may include with a cam surface that is rotatable against a complementary cam surface of an inserter tool such that a first force causes the intervertebral spacer to pivot, relative to the inserter tool, about a pivot point associated with the cam surface.

A driver-specific back-out prevention mechanism is disclosed that includes a screw and a body. A first driver can be used for coupling and decoupling the screw with the body, and a second driver can only be used for adjusting the position of the screw in the receiving body. The body includes a cavity for receiving a head of the screw, with the cavity having an inward flange. The screw includes upper and lower sockets, with a channel extending though the head from the lower socket and a lock body disposed in the channel. Engagement with the first driver allows the locking body to move such that the fastener can be inserted and removed from the body. Engagement with the second driver displaces the locking body such that the locking body interferes with the flange such that screw fastener cannot be removed from the body by the second driver.

The present disclosure includes implant systems, devices, implants, guides, instruments and methods of use. The insertion guide including a base member having a first opening with a first trajectory and a second opening with a second trajectory, a connecting member having a first end and a second end, wherein the first end is coupled to the base member and a locking block coupled to the second end of the connecting member. The locking block has a first guide hole and a second guide hole. The implant including a body including a first hole at a first end of the body, a second hole at a second end of the body, and a locking opening positioned between the first hole and the second hole. Methods of using the implant systems are also disclosed.

A driver-specific back-out prevention mechanism is disclosed that includes a screw and a body. A first driver can be used for coupling and decoupling the screw with the body, and a second driver can only be used for adjusting the position of the screw in the receiving body. The body includes a cavity for receiving a head of the screw, with the cavity having an inward flange. The screw includes upper and lower sockets, with a channel extending though the head from the lower socket and a lock body disposed in the channel. Engagement with the first driver allows the locking body to move such that the fastener can be inserted and removed from the body. Engagement with the second driver displaces the locking body such that the locking body interferes with the flange such that screw fastener cannot be removed from the body by the second driver.

Compression devices for joining tissue and methods for using and fabricating the same.

A fusion device assembly for fusion of a joint, including a fusion device, including a distal end, a proximal end, a radially outward facing surface including threading, a bore extending from the proximal end, at least one flute arranged proximate the distal end, and at least one aperture arranged adjacent to the at least one flute, and a reversibly connected hollow drive shaft for insertion of said device which, in a some embodiments, is hollow to allow addition of supplementary bone graft materials or products, should this be desired, without altering the position of the deployed device.

Orthopedic fixation devices and methods of installing the same. The orthopedic fixation device may include a coupling element and a bone fastener, whereby the bone fastener can be loaded into the coupling element through the bottom of a bore in the coupling element.

A surgical instrument having a first member engageable with a first end of a fastener having a second end configured to penetrate tissue. A second member includes an expandable member configured for engaging the first end. Systems and methods are disclosed.

Disclosed is a surgical assembly for reducing a fracture situated at bone epiphyses or joints including: an osteosynthesis support plate, a set of diaphyseal fixing members, a set of cannulated epiphyseal fixing members, a set of fixing pins, at least one cannulated sighting guide, a cannulated tool for rotating the fixing members and the sighting guide, also acting as a measuring instrument (for determining the length of at least some of the epiphyseal fixing members to be used), a cannulated drilling device (for drilling holes suitable for positioning at least some of the fixing members) and, preferably, an arthroscopic device designed to allow the practitioner to view some of the operative phases.

The present invention discloses single level fusion systems and methods of use. The single level fusion systems include a first fastener, a second fastener, and a connector to secure the first fastener to the second fastener. The method of assembling a single level fusion system including obtaining a first fastener, a second fastener, and a connector, securing the first fastener to the connector, and securing the second fastener to the connector. Methods of using the single level fusion systems are also disclosed.
