A cup and a temporary insert are respectively configured to be tightly press fitted into each other along their periphery. The temporary insert includes a through hole communicating outside with a free space between the outer surface of the temporary insert and the inner surface of the cup. In the through hole can be engaged the threaded end of an impactor, for manipulating the cup when it is being set. A syringe can be engaged, enabling a liquid under pressure to be injected into the free space, thus separating the temporary insert from the cup without any risk of damaging the inner surface of the cup. Thus, the cup can be securely manipulated when it is being set without any risk of damaging the inner surface of the cup.

The present invention relates to an anchoring system for attaching a prosthesis to a human body, comprising: an anchoring element, an abutment, an abutment screw for attaching the abutment to the anchoring element, the anchoring element comprises a connection area for the abutment, the connection area comprising a press-fit portion such that the abutment is attached to the anchoring element in the connection area by a press-fit connection, wherein the connection area comprises an anti-rotation geometry and the abutment comprising a corresponding mating anti-rotation geometry proximal to the press-fit portion, and where in the connection area comprises a conical portion proximal to the anti-rotational geometry forming a mating geometry for a corresponding conical portion in the through-hole of the abutment.

A spacer member is provided that is configured to be implanted adjacent an anatomical structure. The spacer member defines a curved bore, a first opening in a side wall of the spacer member and a second opening in one of a top wall and a bottom wall of the spacer member. Each of the first opening and the second opening are in fluid communication with the curved bore. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member.

Various implementations include an anchoring device including a tubular body and at least one anchor. The at least one anchor extends along an opening between a first axial end and a second axial end of the opening. The at least one anchor includes a shape memory material. The at least one anchor is movable from a retracted position to an extended position by either increasing the temperature of the anchor above an austenite finishing temperature or decreasing the temperature of the anchor below a martensite finishing temperature. The anchor has a smaller radius of curvature in a plane that includes the longitudinal axis in the extended position than in the retracted position. When used as a coupler for medical implants, the device can be easily removed and reimplanted during re-surgery without damaging the bone of a patient by increasing or decreasing the temperature of the shape memory material anchors.

The invention relates to an expandable interbody device used for interbody operations on the spinal column and belongs to the field of medical equipment.

The present disclosure relates to a system for augmentation of a tibial component. The system includes an augmentation component having a first porous structure, a second porous structure, a top portion having a top surface, and a bottom portion having a bottom surface arranged opposite the augmentation component from the top surface. The system also includes a tibial component and an instrument, with the tibial component being configured to couple to the augmentation component. The instrument includes an engagement portion having a geometry complimentary to that of the augmentation component. Further, a method of augmenting a tibial component is disclosed with the steps of collecting imaging data from a patient, identifying a void in the distal tibia, obtaining an augmentation component that corresponds to the void, coupling the augmentation component to the tibial component and implanting the tibial component into the tibia so the augmentation component occupies the tibial void.

A biocompatible construction adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter distinct from the cutting edge. The rotatable cutter allows for graduated cutting of biological tissue or structure.

A universal payload may be integrated with each of a plurality of different orthopedic implants configured to replace or functionally supplement a natural joint of a body. In one aspect, a universal payload includes an electronics assembly, a housing enclosing the electronics assembly, and a payload coupling feature configured to couple to each of a plurality of different orthopedic implants. The electronics assembly includes at least one sensor and a controller having at least two joint-specific modules. Each joint-specific module is respectively configured to collect kinematic data resulting from movement of a respective specific joint sensed by the at least one sensor. In another aspect, a universal payload includes an electronics assembly comprising at least one sensor and a housing enclosing the electronics assembly. The universal payload has a payload form factor that is configured to be at least partially inserted into a payload receptacle in each of a plurality of different orthopedic implants.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

The present disclosure provides an acetabular defect reconstructive prosthesis, comprising: an iliac support, the iliac support including a support seat (11) and a connecting wing plate (12) provided on the support seat (11), and the support seat (11) being contacted and matched with an ilium (1); and an acetabular cup (20) rotatably connected with the support seat (11) together. The technical solutions of the present disclosure can effectively solve the problems of reconstruction and long-term stability of a peri-acetabular defect in the related technology.
