A multi-function device useful in a surgical procedure for implanting a cartilage repairing implant in a bone is disclosed. The device includes a plurality of bone defect sizing rings or discs, where each bone defect sizing ring/disc includes a portion that is used to determine the size that correlates to the perimeter shape and size of the cartilage repairing implant. The inventive device also includes a feature that can be used to gauge the proudness of the cartilage repairing implant after the implant has been implanted into a bone.

Disclosed herein is a toe implant for replacing a portion of a human toe joint, as well as a related kit, surgical method, and method of manufacturing. Specifically, the toe implant may include a bearing member having a curved interface surface and a fixation member coupled to the bearing member. The fixation member may include a first portion having a non-porous barrier, and a tapered second portion.

The present disclosure is directed offset adapters, trial implant systems, shoulder implant systems, and methods for total shoulder replacement, wherein the eccentricity of a humeral head relative to a humeral anchor and resected proximal portion of a humerus is selectable by a surgeon. A humeral head implant system includes a humeral head, an adapter, and humeral anchor. An offset adapter is operable to connect the humeral head to a humeral anchor. The offset adapter includes a first tapered cylindrical portion having a first axis, a second tapered cylindrical portion having a second axis, and the first axis being eccentrically disposed relative to the second axis of the adapter. A trial humeral head system includes a trial humeral head, a pin guide, and a trial adapter.

A coracoid guiding system. The coracoid guiding system includes a coracoid grasper for holding an exteriorized coracoid bone block, and a coracoid passer. The coracoid passer has a pair of external barrels, a pair of internal barrel pins, a hollow guiding tube including an inner surface and an outer surface, and a hook gauge. The hook gauge is configured to be retractably arranged inside the hollow guiding tube. The hook gauge has a proximal end, a distal end, a curved section between the proximal end and the distal end, a first straight section extending from the proximal end to the curved section, a second straight section extending from the curved section to the distal end, wherein the distal end of the hook gauge is shaped as a hook.

A device, method, and system are provided for measuring the fit and mechanical properties of an intended ligament or tendon graft during a surgical procedure. The device includes a sensor body, a set of temporary fixation securements that terminate a set of opposing sides of the sensor body, and electronic circuitry in communication with the sensor body, where the electronic circuitry generates electric signals in proportion to the mechanical properties experienced by the sensor body. The set of temporary fixation securements are adapted to attach to at least one of: (i) one or more patient bones, or (ii) permanent fixation hardware assembled to one or more patient bones.

An orthopedic guide that can comprise a base, a first attachment and a second attachment is disclosed. The base can have a plurality of connection features spaced from one another along a longitudinal extent. The base can be configured to seat on a rim of a bone. The first attachment can be selectively coupled to the base at a first end portion thereof and can be selectively coupled to the base at a second end portion thereof. The first attachment can be arch shaped when coupled to the base. The first attachment can define a first plurality of apertures. The second attachment can be selectively coupled to the base at a first end portion thereof and can be selectively coupled to the base at a second end portion thereof. The second attachment can be arch shaped when coupled to the base. The first attachment can define a second plurality of apertures.

A computer-implemented method for determining implant positions of two implant components relative to two bones that form a joint is disclosed. The method includes acquiring a set of target poses to be achieved between the two bones, assessing one or more proposed implant arrangements using the set of target poses, and selecting an implant arrangement from the proposed implant arrangements based on the assessment. Assessing an implant arrangement includes determining a real pose between the two bones for each target pose, calculating a pose deviation value for each target pose based on the target pose and the corresponding real pose, and calculating an overall pose deviation value from the individual pose deviation values. The implant arrangement may be selected based on the overall pose deviation values for the proposed implant arrangements.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a ball and socket joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation.

Expandable fusion devices, systems, and methods thereof. The expandable implant may include first and second lateral legs and link plates pivotably joined between them. The lateral legs may include upper and lower endplates configured to engage adjacent vertebrae, an actuator assembly including a rotatable actuator having a shaft and a rotatable nut, and driving ramps positioned along the shaft of the actuator. The actuator assembly may cause independent movement of one or more of the driving ramps, thereby causing an expansion in height of the upper and lower endplates of the lateral legs and passive expansion of the connected link plates.
