The present invention relates to bone-implants for treating a lesion on a bone, comprising: a bone anchor, a container in communication with said anchor and an osteoconductive bone-filler material inside said container, and methods thereof.

Apparatus and associated methods relate to a spinal implant configured to expand both vertically and laterally at the same time when wedges coupled by a threaded post drive movable spinal implant endplates radially outward from the longitudinal axis of the threaded post, displacing the wedges and expanding the implant as the threaded post turns. In an illustrative example, the wedges may be a pair of wedges configured with dual inclined planes. The inclined planes may be, for example, disposed both vertically and laterally with respect to the threaded post longitudinal axis, permitting implant expansion both vertically and laterally simultaneously. In some examples, the wedges may be cones. Some embodiments may include an aligning support. In some samples, the aligning support is a pair of rails adapted to prevent rotation of the wedges. Various examples may advantageously provide improved stability and reduced subsidence, based on increased vertebral body contact area with an implant expanded in place to the desired height and width.

A bone graft retention plate for implantation into a human glenoid and provides stabilization and compression of bony graft material is disclosed. The plate includes channels or apertures for suture or polymer retention cerclage that exhibit curved, smooth surfaces within the plate to allow the retention cerclage to pass through the plate while limiting friction and thus protecting the integrity of the retention means. The plate also includes surface features, such as spikes and posts, to provide further stabilization and implantation positioning. The plate features result in the distribution of forces across the surface area of a bone graft and achieve satisfactory compression of the bone graft against the glenoid without using fixation screws. An associated implantation technique uses a cerclage of suture or tape to bind the implant within the glenoid and may be employed in both open and arthroscopic surgical procedures.

Disclosed are devices, methods and/or systems for a partial glenoid implant for use during glenoid arthroplasty, including related surgical methods and instruments.

A medical that is implantable into a human or animal body or being an augmentation device for strengthening human or animal hard tissue for subsequent implantation of a separate implant. The device includes a sheath element suitable of being brought into contact, during a surgical operation, with live hard tissue and/or with hard tissue replacement material. The sheath element has a, for example, generally elongate shape and a longitudinal bore defining a longitudinal opening reaching from a proximal end of the sheath element into a distal direction, and a plurality of holes in a wall of the opening. Further, the device includes a liquefiable element that is insertable or inserted in the longitudinal opening and at least partly liquefiable by the impact of energy impinging from the proximal side.

Embodiments of the invention include a system for coupling a graft to a bone. A graft preparation tool may be used to place one or more holes in a graft and an offset measurement tool may be used to determine the distance of the one or more holes from an edge of the graft to be aligned with a portion of the bone. One or more complementary holes may then be created in the bone and fasteners applied through the holes to couple the graft to the bone.

There is disclosed a bone fixation device that can include a cage having an optional mesh portion. The bone fixation device can be configured to couple a leg portion to a foot portion of a user's body. In at least one embodiment, the device includes at least one cage having a plurality of struts forming cells. There can be an optional mesh portion having a pre-set porosity that can be either constant or variable in density. In at least one embodiment there can be a cage portion which is substantially spherical shaped. Alternatively, the device can be substantially egg shaped. In at least one embodiment there can be a central post hole for receiving a post. In another embodiment at least one plate or shaft can connect to the cage.

The present disclosure relates to a three-dimensionally (e.g., 3D) printed, surgically implantable tissue engineering scaffolds for promoting bone, vascular, and/or cartilage regeneration at osteochondral regions and a method for manufacturing the 3D printed surgically implantable tissue engineering scaffold. The 3D printed surgically implantable tissue engineering scaffold may be fabricated at least in part from a thermoplastic polyurethane (e.g., nTPU) composite via a rapid prototyping machine. In some cases, the three-dimensional shape of the fabricated tissue engineering scaffold may correspond to a three-dimensional shape of a tissue defect of a patient.

Provided is a dental dual-structured membrane. The dental dual-structured membrane according to an embodiment of the present inventive concept includes a shielding portion for shielding a bone grafting material and an alveolar bone from the outside to prevent infiltration of other tissue cells, and an insertion and fixing portion connected to the shielding portion and inserted between a gum and the alveolar bone to fix the shielding portion, in which the insertion and fixing portion has a higher tensile strength than the shielding portion.
