ANGLED SPINAL FIXATION PLATE
The present invention relates to an implantable anterior cervical plate having a stackable superior design, which deflects soft tissue.
SYSTEMS AND METHODS FOR USING POLYAXIAL PLATES
Certain embodiments of the invention provide plates for treating periarticular fractures or other non-full body weight bearing applications that combine polyaxial fixation with a low profile and enhanced contouring that more closely conforms to bone. Such plates can be designed to achieve buttressing effect and/or to be used in a reinforcement mode. Other features can be combined with these. Such plates can be created for use on bone sites such as on a tibia, fibula, metatarsal, calcaneous, other foot bone, humerus, radius, ulna, spinal, maxillofacial, as well as sites on other bones.
ZERO-PROFILE INTERBODY SPACER AND COUPLED PLATE ASSEMBLY
An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.
Zero-profile interbody spacer and coupled plate assembly
An implant for insertion into the disc space between vertebrae. The implant including a spacer portion, a plate portion coupled to the spacer portion, a plurality of bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively uncoupling from the implant.
Lordotic expandable fusion implant
The present disclosure provides an expandable spinal implant comprising a plurality of moveable endplates pivotably connect to a housing.
Orthopedic anchor assembly
An orthopedic assembly is described that comprises an orthopedic device, an anchor, and a locking mechanism. The orthopedic device can be a plate member having an aperture that is configured to receive the anchor. The anchor can include a head, neck and shank portion. The head portion can include a plurality of arms separated by grooves that are capable of splaying. The assembly is configured such that when the locking mechanism is inserted into the head portion, this causes expansion of the arms of the head. This expansion locks and secures the anchor to the orthopedic device. Various instruments are provided that can deliver the locking mechanism to the anchor, and can provide impact to lock functionality.
Polyaxial bone plate and locking assembly
A bone plate and one or more locking assemblies that help prevent screw backout without impinging on therapeutically valuable settling of the screws. In some cases, the locking assembly is configured to be attached to the plate, to be securely but efficiently locked, to be readily unlocked for revision surgery, and/or to reduce the possibility of operator error in installation by providing simplified visible and tactile indicia of the locked and unlocked positions.
Implantable systems, devices and related methods
The present application is generally directed to implantable systems, devices and related methods pertaining to spinal surgery. In particular, the present application discloses a frame and spacer system for inserting into a disc space. The frame and spacer system is of low profile. The frame can receive different fixation devices, including threaded and non-threaded fixation devices.
Zero-profile interbody spacer and coupled plate assembly
An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.
SYSTEMS AND METHODS FOR ORTHOPEDIC IMPLANT FIXATION
A personalized fixation system includes a surgical planning software tool configured to adjust relationships of relevant anatomy of a subject, at least one bone anchor, a plate having a shape that does not conform to a single plane, the plate configured to accept the at least one bone anchor, wherein the shape of the plate is at least partially determined by the surgical planning software tool, and wherein the plate includes at least one node having a hole configured to receive the at least one bone anchor, and a locking element configured to connect the at least one bone anchor to the plate, wherein the plate is manufactured using additive manufacturing.
