An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.

Intervertebral implant with keel

The present disclosure provides a modular instrument system for accessing a site within a patient's body, such as for example, to inject or remove material. In one exemplary embodiment, an access device is coupled to an adapter and power drilled into a site within a patient. Once the access device is in position, the adapter may be further attached to other instruments, or to an injection or extraction system. The adapter may accommodate various other connectors to make the instrument system compatible with a variety of other surgical instruments and tools.

Surgical access systems, instruments and accessories

An instrument for navigating to a target area near a subchondral defect of a bone and associated methods are disclosed. The instrument can include a body portion having a patient specific surface defining a negative impression of a portion of a skin surface of a patient, and a targeting device coupled to the body portion, the targeting device including a rail and at least one device portal configured to guide a device into a subchondral region of the bone for treatment at the target area.

Navigation instruments for subchondral bone treatment

A minimally invasive fixation system and method for providing access to a surgical site. The fixation system may include a holding assembly, the holding assembling preferably including a lateral implant holder which may be attached to a pedicle screw and a sleeve positioned in connection with the lateral implant holder to prevent the lateral implant holder from separating from the pedicle screw. The sleeve may further include a tissue protection portion to keep the tissue out of the surgical site. A holding sleeve may be operably connected to the holding assembly and pedicle screw and may be used to insert the pedicle screw into the body. Multiple constructs may be inserted into the body so that a portion of the holding assembly extends from the body and provides access to and visualization of the surgical site. A rod holder may also be used to insert a rod into the head of the screw. The rod may be held by the rod holder so that the rod may be angulated as the rod is inserted into the screw heads. Once the rod is positioned in the screw heads, locking caps and/or set screws may be positioned over the rod and engage the screw heads so that the position of the rod may be fixed with respect to the screws. In some embodiments, a movement mechanism may be used to move the screws relative to each other to compress and/or distract the vertebrae.

Minimally invasive fixation system

Instruments and associated methods are disclosed for treating joints, and particularly bone tissue. In general, the embodiments relate to instruments and associated methods for the surgical treatment of a joint, and particularly to a subchondral bone defect at that joint region. More specifically, the embodiments relate to instruments that allow fast, easy, precise, and controllable subchondral delivery to, or removal of materials from, a bone joint being treated.

Instruments and devices for subchondral joint repair

One embodiment disclosed provides a guide instrument for controlling the depth and trajectory of a surgical access device into a bone.

Surgical access tools, guide instruments and accessories for subchondral treatment of bone

A system and associated instruments for locating, and accurately and controllably delivering, a device to an area sufficiently near a bone defect using anatomical landmarks is provided. The instruments allow the surgeon to navigate to the area around the bone defect quickly and easily, while so facilitating proper insertion of the device. In some embodiments, the defect is located on a femur. Guide instruments having a plurality of device portals are also provided for use as standalone instruments or as accessories to the system. In addition, a protective guide sleeve is provided for the insert of small diameter devices.

Navigation and positioning systems and guide instruments for joint repair

Devices, instruments and associated methods for the subchondral treatment of osteoarthritis in small joints are provided. In addition, a method for treating joint pain in small joints is provided. These small joints may be ankle, elbow or wrist joints. The methods may target one of many different access points having trajectories with a common focal point at or near the small joint. The instruments may limit access to areas within or near the small joint by providing predefined entry paths that avoid damage to surrounding tissues.

Methods and instruments for subchondral treatment of osteoarthritis in a small joint

Navigation instruments and guides for targeting a subchondral region of bone and subchondral bone defects are provided. The instruments and guides may be used in reference to an anatomical landmark of a joint.

Implantable devices for the surgical treatment of bone, and particularly to a bone defect at a joint region, and even more particularly at the subchondral bone level of the joint region, are disclosed. The implantable devices may be formed of a bone material, and configured to serve the dual functions of providing mechanical strength and structural integrity to the area to be treated, while also facilitating the dispersal of a flowable material in the same area. Associated delivery tools are also provided.
