IMPLANT FOR CARTILAGE AND/OR BONE REPAIR

A medical implant for cartilage and/or bone repair at an articulating surface of a joint includes a contoured implant body and at least one extending post. The implant body has an articulating surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the articulating and bone contact surfaces face mutually opposite directions and the bone contact surface is provided with the extending post. A cartilage contact surface connects the articulating and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The articulating surface has a layer that is a wear-resistant material. The cartilage contact surface has a coating that is a bioactive material.

Described is a femoral component of a prosthetic hip implant. The femoral component can include: a neck portion; and a stem portion including a proximal end and a distal end. The neck portion extends from the proximal end, and the stem portion comprises a first solid portion and at least one additional portion including at least one of a hollow portion, a porous portion, and a second solid portion comprised of a different solid material from a solid material of the first solid portion. The first solid portion and the at least one additional portion are in a predetermined configuration. The femoral component comprises a unitary component that is formed by additive manufacturing of the femoral component from a 3D model of the femoral component.

SUBCHONDRAL TREATMENT OF JOINT PAIN OF THE SPINE

Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.

Modular humeral head resurfacing system

A two piece humeral component for use in joint arthroplasty which is adapted to be implanted into a joint and engaged by a socket component of the joint. The joint component includes a body having a first articulating surface and a second medial surface opposite the first articulating surface. The first articulating surface is adapted to be engaged by the socket and the second medial surface is adapted to be secured to mounting portion. The mounting portion has a first surface and a second medial surface. The first surface is adapted to be fixably engaged to the second mounting portion of the humeral component. The second medial surface is adapted to be secured to the humerus. A peg which has a first end adapted to engage a cavity found in the humerus is disposed on the mounting portion's second medial surface.

DISK-SHAPED AUGMENTATION FOR A BONE, PARTICULARLY A LONG BONE
20240341965 · 2024-10-17 · ·

Disk-shaped augmentation for filling bone defects, in particular at the end of long bones, such as the tibia, including a first side, a second side, an outer sheath on lateral sides and an inner wall for a through-opening, running from the first to the second side, for a anchoring keel of an endoprosthesis arranged on the second side. The augment is generally C-shaped with two legs flanking the through-opening. According to the invention, a connecting piece between the legs is designed in an articulated manner and cooperates resiliently with the legs such that a frame is formed, and an outwardly directed restoring force is generated when the legs are compressed.
