Abstract: A mobile bearing prosthetic implant may include a fossa implant seated in the fossa cavity of the skull and secured to the zygomatic arch. The fossa implant may define a primary recess constructed and arranged to mimic the articular eminence of the temporal bone such that a floating bearing connected to a ramus implant may translate along the original path that the condylar head would take during movement of the jaw. The floating bearing may be constructed and arranged to move from the first jaw angle recess to the second jaw angle recess and is positionable therebetween such that a longitudinal axis of the floating bearing is perpendicular to the direction of movement of the floating bearing within the fossa implant.

Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.

Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery which promotes proper positioning and orientation on a resected tibia, while also facilitating enhanced kinematics, soft-tissue interaction, and long-term fixation of the complete knee prosthesis. The asymmetric baseplate periphery is sized and shaped to substantially match portions of the periphery of a typical resected proximal tibial surface, such that proper location and orientation is evident by resting the baseplate on the tibia. The baseplate periphery provides strategically positioned relief and/or clearance between the baseplate periphery and bone periphery, such as in the posterior-medial portion to prevent deep-flexion component impingement, and in the anterior-lateral portion to avoid undue interaction between the anatomic iliotibial band and prosthesis components.

The first side wing, the second side wing, the third side wing, and the fourth side wing each have a through hole.

Abstract: Bone anchors and bone anchor insertion systems are provided that enable smaller bone holes for inserting a bone anchor by eliminating the need for a cannula. Smaller bone holes may help reduce patient recovery times. The provided bone anchor includes two flexible wings extending from a base portion that splay away from the base portion's central axis at rest, though may be bent towards or away from the central axis in response to an applied force. The bone anchor includes a drive feature that enables an inserter to couple and decouple to the bone anchor. A surgeon may drive the bone anchor through a bone hole via the coupled inserter while the bone hole maintains the bone anchor in a compressed state, and may decouple the inserter when the bone anchor is properly positioned, thereby eliminating the need for a cannula.

Abstract: A method of forming a patient-specific-bone-graft cage based on a patient-specific bone graft cage computer model that is based on a contour of a surface of the bone defining a void, and/or a patient-specific-bone-graft cage that includes a plurality of apertures, that terminate at a location between a front surface and a back surface of the patient-specific-bone-graft cage, for receipt of bone graft material. The patient-specific-bone-graft cage can construct an essential portion (including complex thin anatomical structures) of or substantially the entirety of the mid-face region (e.g., to fill a void in a damaged orbital region), which enables an improved structure reproduction and simplification for the surgeon. For example, the patient-specific-bone-graft cage may be formed based on the contour of the periphery defining the void in the damaged region, and require less modification by a surgeon compared to graft cages formed only by mirroring techniques or normalized models.
