The present invention discloses a prosthetic device for reconstruction of sternum, ribs, and clavicles, comprising a manubrium plate attached to a sternum plate by means of a joining plate. The manubrium plate has spherical ends coupled to the clavicle plate by screwing into a cup lock. The manubrium plate has extensions with holes, on which rib plates are seated. Similarly, the sternum plate has extensions with holes, on which rib plates are seated.

A monolithic rib plate is described. The rib plate comprises multiple first screw orifices located substantially along a first line and connected by first bridges, multiple second screw orifices located laterally on one side of the first line and connected by second bridges, wherein one or more of the second bridges have a smaller cross-section than the first bridges, and third bridges, each connecting one of the second screw orifices with one of the first screw orifices. Also described is a rib plate system comprising the monolithic rib plate and at least one of one or more polyaxial locking screws, a tool for removing the second bridges, a tool for bending the monolithic rib plate, and one or more orifice bridge plates.

An adhesive device for biomedical applications is provided comprising a support and one or more water insoluble compounds of structure 1 wherein B is an oligomer derived from a polyester, polyether, polyalkylene glycol, polysilicone or polycarbonate with a MW<10,000 g/mol, Linker L is a urethane, urea bond, or amide bond; Linker L′ is a urethane or urea bond, A is a chain extender of Mw≤3000 g/mol comprising substituted or unsubstituted alkyl, cycloalkyl and/or aromatic groups, W is a terminal adhesive benzene-1,2-diol derivative or a terminal adhesive benzene-1,2,3-triol derivative, m is 0 or 1; and n is 0, 1, 2, 3 or 4 or a cross-linked polymer formed from said compounds. The compound(s) have a Tg lower than 25° C. Structure 1

An implantable body for a posterior stabilization system includes a lateral end, a medial end, an inwardly facing surface configured to abut against a lamina when the body is implanted along a vertebra. A lateral bone outrigger extends from the inwardly facing surface and may include a bone-abutting surface along a medial portion disposed to abut against a lateral mass of the vertebra when the body is implanted along a vertebra. The lateral bone outrigger may have a first height. A penetrating feature extends from the inwardly facing surface between the bone-engaging portion of the inwardly facing surface and the lateral bone outrigger. The penetrating feature may have a second height less than the first height. A fastener bore extends through the body at an angle toward the lateral bone outrigger.

The present disclosure concerns a subperiosteal dental implant for receiving at least one replacement tooth of a patient, the subperiosteal dental implant comprising an implant frame superposable to at least a section of a jaw hone of the patient, the implant frame having a bone-facing surface at least partially contacting the jaw hone of the patient when the implant frame is superposed thereto, and an opposed gum-facing surface, the implant frame having at least a section along which a cross-section profile includes a base defining at least partially the bone-facing surface and at least partially the gum-facing surface, a ridge protruding from the base and defining at least partially the gum-facing surface, and a first shoulder and a second shoulder that are both defined on the gum-facing surface of the base, each one being located on a respective side of the ridge.

A patella fracture fixation system includes a peripheral rim bone plate that is configured to be implanted along a parapatellar lateral approach. The bone plate can configured to minimize disruption of blood supply to the patella. The bone plate can be augmented with a Krackow suture pattern to assist in stabilization of a comminuted inferior pole.

Lamina plate assemblies, systems, and methods thereof. A lamina plate assembly may be configured to provide lamina support following laminectomy, for example, in cervical and lumbar cases. The lamina plate assembly may include a generally elongate body having a first free end, a second free end, and a posterior portion disposed between the first free end and the second free end. Different embodiments of securing portions are used to secure the lamina plate assembly to a vertebra.

A system and method for providing enhanced information to a surgeon is described. A three-dimensional reconstruction of a patient's anatomical structure selected for surgery and a representation of a surgical treatment apparatus are rendered on a display device. At least one attachment metric for a proposed attachment between the surgical treatment apparatus and the patient's anatomical structure is calculated using the three-dimensional position of the surgical treatment apparatus relative to the patient's anatomical structure. And, an indication of the attachment metric is rendered on the display device.

An implant in the form of a bone screw that meets device tracking requirements set for the in the FDA regulations is provided. The bone screw includes a screw body and a tag body formed as an integral extension of the screw body and is connected to the screw body via a frangible interface bone screw. The screw body has a head portion and a threaded shaft portion that extends along a longitudinal axis from the head portion to a screw tip of the screw body. The tag body defines at least one surface configured to display traceability information for the bone screw. The frangible interface is disposed between the tag body and the screw tip of the screw body. The frangible interface is configured to fracture upon application of a predefined mechanical force so that the tag body is removable from the bone screw.

The present technology provides patient-specific implants. The implants can include a plate having a geometry contoured to mate with an identified anatomical structure at a target position. The plate can include a first projection having a first contact surface with a first topography designed to mate with a corresponding first surface of a first vertebral body, and a second projection having a second contact surface with second topography designed to mate with a corresponding second surface of a second vertebral body. The first topography can be different than the second topography. In some embodiments, the first and/or second projection can be configured to contact, and have topographies designed to mate, with a plurality of surfaces, such as two adjacent surfaces, of the respective first and second vertebral bodies.
