Anatomically relieved augments

Anatomically shaped augments that are configured for implantation in a bone and which have one or more reliefs. A distal end of an outer portion of the augment can have a shape that is configured to generally conform to the shape of a metaphyseal-diaphyseal junction of an intramedullary canal of a bone. A proximal end of the outer portion can have a shape that is configured to generally conform to a shape of the metaphyseal region of the intramedullary canal. The reliefs can be configured to reduce a size of the augment and enhance the degree of freedom in the implant positioning and/or sizing of the augment. Further, such reliefs may contour the augment so as to prevent cortical bone contact and/or prevent contact with the implant device that may be associated with misalignment between an intramedullary canal and metaphyseal or diaphyseal regions of the bone.

An implant, in particular for the treatment and/or biological reconstruction of a bone defect, includes osteoconductive supporting bodies and a supporting sheath at least partially surrounding the osteoconductive supporting bodies. The sheath can be formed of a sheath material or can consist of a sheath material that is soluble in water or in water-containing liquids. A kit and method for the treatment and/or biological reconstruction of a bone defect can utilize a sheath for osteoconductive supporting bodies and a material for sheathing the osteoconductive supporting bodies.

Implant with multi-layer bone interfacing lattice

An implant includes a body including a substrate and a bone interfacing lattice disposed on the substrate. The bone interfacing lattice includes at least two layers of elongate curved structural members. In addition, the at least two layers of elongate curved structural members include a first layer adjacent the substrate and a second layer adjacent the first layer. Also, the first layer has a first deformability and the second layer has a second deformability, wherein the second deformability is greater than the first deformability.

Femoral hip joint spacer with irrigation device
11109977 · 2021-09-07 · ·

A femoral hip joint spacer. The spacer has a prosthesis body with a ball head, a neck, a stem and an anchoring sleeve which encloses the stem on a proximal side of the stem with a circumferential fastening area, irrigation liquid inlet and outlet openings in the body surface, at least one irrigation liquid discharge opening on a distal side of the stem and at least one irrigation liquid intake opening on the ball head or on the neck. The discharge opening is connected in a liquid-permeable manner to the inlet opening but not to the outlet opening and the intake opening is connected inside the prosthesis body in a liquid-permeable manner to the outlet opening but not to the inlet opening. A cavity open on two sides is formed inside the anchoring sleeve and connects a proximal side to a distal side of the sleeve in a liquid-permeable manner.

ANATOMICALLY SHAPED AUGMENTS

Augments for implantation of an orthopedic implant device in a bone. A distal end of an outer portion of the augment can have a shape that is configured to generally conform to the shape of a metaphyseal-diaphyseal junction of an intramedullary canal of the bone. Further, a proximal end of the outer portion of the augment has a shape that is configured to generally conform to a shape of the metaphyseal region of the intramedullary canal. Additionally, the shape of the outer portion at the distal end can be separated from the shape of the outer portion at the proximal end by a distance that is approximately equal to the distance between the metaphyseal-diaphyseal junction and the metaphyseal region of the intramedullary canal.

The invention also relates to a kit consisting of a bone augmentation piece (1) of this type, comprising an implant inserted thereinto, such as a dental implant. The invention also relates to the use of the claimed bone augmentation piece (1) as a drill jig (18).

Tapered fixation device for a knee replacement
11020233 · 2021-06-01 ·

A fixation device for a knee replacement. The fixation device includes a stem configured to be fixedly attached to one of a tibial component of the knee replacement and a femoral component of the knee replacement. The stem has a continuously tapered outer surface and has a distal end that is distal to said one of the tibial component and the femoral component. A tapered projection is positioned on the continuously tapered outer surface and is tapered in the same direction as the continuously tapered outer surface. The stem and the tapered projection are configured so that the continuously tapered outer surface and the tapered projection engage a patient's bone when the stem is inserted into a bone canal within the patient's bone. In addition, the continuously tapered outer surface of the stem at the distal end of the stem and the tapered projection are configured to mechanically fix the knee replacement to the patient's bone by being wedged within the bone canal.

INSET/ONLAY GLENOID, POROUS COATED CONVERTIBLE GLENOID, AND HUMERAL HEADS WITH TEXTURED UNDERSIDES
20210137693 · 2021-05-13 ·

Disclosed are prosthesis systems and methods that provide porous fixation rings by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.

Systems and methods for attaching sleeve or cone in prosthetic implant having a stem
10987225 · 2021-04-27 · ·

A prosthetic implant system for reconstructing a knee joint comprises a prosthetic implant and sleeve. The prosthetic implant comprises a tibial tray component for reconstructing a tibia of the knee joint, and a stem configured to extend from the tibial tray component to anchor the tibial tray component in the tibia of the knee joint. The sleeve comprises an outer wall configured to engage with bone, and an inner bore configured to receive the stem. The inner bore is shaped to couple to the prosthetic implant at a first location proximate the tibial tray component while surrounding the stem, and uncouple from the prosthetic implant at a second location spaced from the first location while still surrounding the stem. Methods employing the prosthetic implant system can comprise intraoperatively determining to use the sleeve in a coupled or un-coupled configuration based on a depth of a broach into a broached channel.
