Disclosed herein is a guide device and a driver, which allows for the preparation of an anatomic cavity for screw fixation of an implant or spacer, including the guidance for hole preparation, and guidance for insertion of screws, and or anchors, while selecting the amount of rigidity, and selecting the amount of visibility.

Inserter guide and driver system

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.

Apparatus for driver-specific backout prevention

Reamer instruments and related methods are disclosed for use in preparing bone, such as a glenoid bone surface, to receive an implant requiring one of two or more possible surface geometries. Described reamer instruments can have a modular or multi-component design. A minimal number of components can be particular to a particular required geometry, which can allow assembly and use of reamer instruments of the present disclosure to be flexible, intuitive, and efficient. In some embodiments, a disposable reamer head assembly can be driven by a disposable drive tip through a pin-on-pin connection. The remaining components of the reamer instrument can be sterilized and re-used. To prepare bone for a half-wedge implant, a half-wedge housing can be coupled to a reamer instrument handle and a depth stop can be coupled to the housing to achieve the required geometry. Alternatively, a full-wedge housing can be coupled to the instrument handle.

Kerrison rod reducer

A spinal fixation device is provided having first and second elongate members that are angularly adjustable relative to one another. Each elongate member can include a connecting feature formed on a terminal end thereof, and each connecting feature can be coupled to one another to allow angular movement of the first and second elongate members. The device can also include a locking mechanism that is adapted to couple to the connecting feature on each of the first and second elongate members to lock the elongate members in a fixed position relative to one another.

Adjustable-angle spinal fixation element

An intervertebral implant frame that is configured to engage a spacer can include a pair of arms that extend longitudinally from a support member such that the arms engage the spacer. The spacer can be made from bone graft, and include a first spacer body made of cortical bone, and a second spacer body made of cancellous bone.

Intervertebral implants, systems, and methods of use

Kerrison-style rod reducers, inline-style rod reducers, and related methods of using the disclosed rod reducers for holding a spinal implant and seating a fixation rod in a rod-receiving portion of the spinal implant are provided for herein. The disclosed rod reducers can also be configured for applying a set screw or other closure mechanism to secure the rod within the rod-receiving portion of the spinal implant. The disclosed embodiments can be easy to use, not require significant force to operate, and be efficient, thereby reducing the time and expense necessary to perform spinal surgery. The disclosed rod reducers can be readily dissembled, thereby making these surgical instruments easy to clean and sterilize.
