An implantable medical device for implantation in a hip joint of a human patient is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

An implant for at least partially filling a bore hole in a bone includes a biocompatible plate and a support structure. The support structure has a ring-shaped inner support frame having an outer surface defining the outer diameter of the inner support frame and an inner surface, and an outer support frame having a plurality of fastening points adapted for attaching the implant to bone surrounding a bore hole in which the plate is inserted. The outer support frame is connected to and extends away from the outer surface of the inner support frame. A method of forming the implant is also provided.

A composition and methods thereof include bone fibers made from cortical bone in which a plurality of bone fibers are made into shapes that are used to augment rotator cuff and acl repair. Sheets of bone fibers may be used as an interface between bone and tissue, tendons, and/or ligaments. The physical presence of the fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation. A delivery system and methods of use are also provided.

Pedicle bone anchor implants, assemblies, and methods thereof. The implant may include an expandable anchor having a body with expandable sections separated by one or more expansion joints, a plurality of expandable teeth, or an expandable head. The expandable anchor has a collapsed configuration and an expanded configuration, thereby creating a press-fit in adjacent bone.

A composition and methods of making or use thereof include a plurality of fibers forming a shape for augmenting tendon to bone repair. The physical presence of the plurality of fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation around the site of the tendon to bone repair.

Innovative orthopedic implant assemblies, devices, and methods are provided. One example assembly includes two implant devices. An example implant device includes two ends oppositely located with a bulbous portion located at one end and a screw portion located at the opposite end. An example second implant device includes two ends oppositely located with a looped portion defining an aperture located at one end and a nail portion located at the opposite end. The nail portion can include a tip and a smooth or substantially smooth portion. The second implant device can be implanted into a bone by striking the looped portion to facilitate the tip and at least part of the nail portion penetrating the bone.

Bone attachment shim device composed of a biomaterial compatible with bone and provides an enhanced surface area on the outer surface of the device for engaging the bone, an enhanced surface area within the device for engaging the bone screw, and is composed of a partial shaft design which is greater than 180 but less than 270 degrees around when viewed in cross section. The device preferably has a biased tip for facilitating placement into bone tissue.

An on-bone robotic system may have a bone anchor device configured to be received in a bone, the bone anchor device including at least one sensor for tracking an orientation of the bone. A robotic tool unit may be releasably connected to the bone anchor device, the robotic tool unit including one or more actuators for displacing a surgical implement of the robotic tool unit relative to the bone when the robotic tool unit is connected to the bone anchor device. The on-bone robotic system includes one or more joints enabling a degree(s) of freedom of movement of the surgical implement relative to the bone anchor device. The on-bone robotic system includes a processor for operating the at least one actuator as a function of the tracking of the bone by the sensor.

An intra-osseous support structure can be used to fixate opposed portions of bone. In some examples, the intra-osseous support structure is positioned in openings formed in adjacent portions of bones. Fasteners are inserted through the bone portions to secure the intra-osseous support structure in the bones. Depending on the application, one or more external bone plates may also be applied to the bone portions. The external bone plate may be in compression while the intra-osseous support structure is in tension under load in situ.
