A bone plate incorporating a length adjusting elongate hole formed in a shaft portion thereof, along with corresponding methods of use. In one embodiment, the length adjusting elongate hole is configured to receive one or more bone fixation devices (e.g., bone screws). In use, the bone fixation device positioned within the length adjusting elongate hole may be partially loosened, without removal, to enable the patient's bone to be adjusted (e.g., loosening the bone fixation device within the length adjusting elongate hole allows the surgeon to adjust the position of the patient's bone, and hence the bone fixation device coupled thereto, relative to the bone plate). Once properly adjusted, the bone fixation device positioned within the length adjusting elongate hole may be retightened. In various embodiments, the length adjusting elongate hole is configured so that, in use, each of the plurality of bone fixation openings remains available to a surgeon.

Bone plate with length adjusting elongate hole, and corresponding methods of use

A targeting system is disclosed. In use, the targeting system is configured to target (e.g., aim, locate, etc.) a fastener opening in a bone plate, more particularly, a variable angled fastener opening formed in a periphery of a periprosthetic bone plate. In one embodiment, the targeting system includes an alignment guide including a plurality of combo-slots for targeting a plurality of openings formed in the periprosthetic bone plate. In addition, the targeting system includes a plug configured to be positioned within the combo-slots formed in the alignment guide. In use, positioning the plug into the combo-slot formed in the alignment guide transforms the combo-slot into a substantially circular hole or opening with a predefined trajectory aligned with one of the variable angled openings formed in the periphery of the periprosthetic bone plate thereby defining a trajectory from the alignment guide to the variable angled opening.

Targeting system for a periprosthetic bone plate

An orthopedic implant including an outer surface and at least one opening extending through the outer surface for receiving a fastener for coupling the implant to a patients bone or bone portion/fragment. The opening including a plurality of fins circumferentially disposed about the opening for engaging threads formed on a head portion of the fastener to secure the fastener to the implant. The plurality of fins being arranged and configured in first and second vertically spaced rows of fins. At least one of the fins including a different configuration, property, etc. relative to at least one of the other plurality of fins. In one embodiment, each of the first and second fins in a vertically stacked relationship includes a different configuration from the other of the first and second fins in that stack. In one embodiment, the different configuration includes a different length, a different thickness, or a combination thereof.

Orthopedic implant with improved variable angle locking mechanism

Variable angle holes in bone plates structured to facilitate the formation of axial compression or tension of a bone, or which can assist in bone distraction. The variable angle hole can extend about a central axis and includes an inwardly extending wedge wall. The variable angle hole can be sized to receive insertion of a fixation element at a location at which a central longitudinal axis of the fixation element is axially offset from the central axis of the variable angle hole by an offset distance at least when the fixation element is initially driven into bone at least in a transverse direction. The wedge wall can be configured to be engaged by a portion of the fixation element in a manner that axially displaces at least one of the bone plate, the fixation element, and/or bone(s) in a direction that can generally reduce or increase the offset distance.

Bone plate

An orthopedic instrument for manipulating (e.g., compressing or distracting) one or more patient's bone fragments is disclosed. In one embodiment, the orthopedic instrument includes forceps having first and second arms and first and second handles, respectively. Each arm including a coupling mechanism for selectively engaging removable tips or bell housings. Each tip or bell housing including a first end arranged and configured to mate with a fastener hole or opening formed in a bone plate, a second end arranged and configured to receive a head portion of a bone fastener, and an intermediate portion arranged and configured to couple to the coupling mechanism of the first and second arms. In addition, the orthopedic instrument may include a force sensing mechanism or gauge arranged and configured to measure an amount of force being applied across the bone fracture.

Bone reduction instrument, system, and method

Variable angle holes in bone plates that are structured to facilitate the formation of axial compression or tension of a bone, or which can assist in bone distraction. The variable angle hole can extend about a central axis and includes an inwardly extending wedge wall. The variable angle hole can be sized to receive insertion of a fixation element at a location at which a central longitudinal axis of the fixation element is axially offset from the central axis of the variable angle hole by an offset distance at least when the fixation element is initially driven into bone at least in a transverse direction. The wedge wall can be configured to be engaged by a portion of the fixation element in a manner that axially displaces at least one of the bone plate, the fixation element, and/or bone(s) in a direction that can generally reduce or increase the offset distance.

Embodiments of the invention are directed to a caddy configured to receive medical implants coupled to respective holders. The medical implants and holders may be oriented and/or located in the caddy based on one or more of size, shape, and other configuration of the medical implants and holders and the openings in the caddy through which the medical implants are received. Another embodiment of the invention incudes a medical implant having an implant body portion and a detachable marking portion that is connected to the implant body portion by a frangible region structured to provide selective separation of the implant body portion from the detachable marking portion upon application of a force or torque to the implant body portion, and the detachable marking portion including one or more markings that correspond to identifying information associated with features or characteristics of the implant body portion.

A system () for identifying a landmark is disclosed. The system includes a field generator () for generating a magnetic field, an orthopedic implant () located within the magnetic field, the implant having at least one landmark (), a removable probe () with a first magnetic sensor (), a landmark identifier () with a second magnetic sensor () and a processor () for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.

A field generator for use in a surgical targeting system is disclosed. The field generator includes a mounting structure including elements that are configured to receive components of an electromagnetic field generator. The elements are disposed on the mounting structure at locations and orientations relative to each other. The field generator includes at least one covering formed over the mounting structure, wherein, in use, the locations and orientations of the elements relative to each other remain substantially unaltered after exposure to one or more sterilization processes.

A system for targeting landmarks on devices such as surgical implants is disclosed. The system can include a field generator for generating one or more magnetic fields, an orthopedic implant located within the magnetic fields, the implant having at least one landmark, a removable probe with a first magnetic sensor, a landmark identifier and a processor. The landmark identifier can contain a second sensor, or, alternatively, the field generator. The processor can utilize sensor data and, if desirable, field generator and other information, to generate and display the position and orientation of the sensor(s) in preferably six degrees of freedom, and thereby, to generate and display the position and orientation of the landmark(s). The system allows for blind targeting of one or more landmarks. The landmark identifier, field generator and/or drill motor may be disposed in an autoclavable housing.
