An orthopedic prosthesis for stimulating bone growth may include a substrate having at least one bone-facing surface and at least one internal surface, at least one piezoelectric nanostructure coupled to the at least one bone-facing surface of the substrate, at least one charge storing material placed within the orthopedic prosthesis proximate the at least one internal surface, and an interconnect in electrical communication with the at least one piezoelectric nanostructure and the charge storing material. The at least one piezoelectric nanostructure may be configured to generate an electric charge in response to at least one mechanical force applied to the at least one piezoelectric nanostructure and the interconnect may be configured to transfer the electric charge to the at least one charge storing material to promote bone in-growth within the orthopedic prosthesis and/or on the at least one bone-facing surface.

A system and computer-implemented method for manufacturing an orthopedic implant involves segmenting features in an image of anatomy. Anatomic elements can be isolated. Spatial relationships between the isolated anatomic elements can be manipulated. Negative space between anatomic elements is mapped before and/or after manipulating the spatial relationships. At least a portion of the negative space can be filled with a virtual implant. The virtual implant can be used to design and manufacture a physical implant.

A reverse shoulder system can include, for example, a glenoid baseplate comprising a longitudinal axis, the glenoid baseplate further including a stem and a central channel within a sidewall of the stem. The stem can include a longitudinal axis. The longitudinal axis of the glenoid baseplate can be angled with respect to the longitudinal axis of the stem, wherein the longitudinal axis of the glenoid baseplate is not perpendicular with respect to the longitudinal axis of the stem. Other components including a glenosphere, tools, and methods of use are also disclosed.

Compositions and methods for making biocompatible articles are provided. A method includes preparing a 3D printable mixture and depositing successive layers of the mixture in a predetermined pattern to form a porous biocompatible article. The predetermined pattern has a porosity suitable for a bone or cartilage scaffold. Associated 3D printable compositions and porous articles made from the described methods are also described. The preparing a 3D printable mixture can comprise conjugating an alkyne-terminated polymer to a peptide to form a peptide-containing composite, or providing a mixture that comprises a ceramic material and a binder, and wherein the 3D printable mixture comprises from 50 wt. % to 80 wt. % of the ceramic material.

A medical honeycomb structure lacking at least a portion of an outer peripheral side wall of a honeycomb structure that includes a plurality of through-holes extending in one direction, wherein sites lacking the outer peripheral side wall have a plurality of grooves, and have a plurality of planes including distant surfaces of groove side walls flanked by the grooves.

Disclosed herein is a toe implant for replacing a portion of a human toe joint, as well as a related kit, surgical method, and method of manufacturing. Specifically, the toe implant may include a bearing member having a curved interface surface and a fixation member coupled to the bearing member. The fixation member may include a first portion having a non-porous barrier, and a tapered second portion.

An ankle prosthesis is provided that includes a tibial stem with a retractable member configured to be controllably movable between a retracted position and an extended position so that in the extended position the retractable member engages the surface of the bone that defines an intramedullary canal so as to enhance anchoring of the tibial stem within the tibia.

An orthopedic implant can be used for fixation of a joint or fracture and can include a tapered member and at least one fixation member. The tapered member can be configured for placement in association with one or more bone segments. The tapered member can have a longitudinally extending body that defines an upper surface portion, an opposed lower surface portion and first and second sides, where at least the first and second sides can be formed of porous metal and can have a porous metal outer surface. The at least one fixation member can be integrally formed with the tapered member and can extend laterally outwardly from the tapered member body. The at least one fixation member can be configured to secure the implant to the one or more bone segments to provide fixation of the one or more bone segments relative to the tapered member.

An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.

An implant may include a body having a first portion and a second portion and a structural member having a central member curve. In addition, the structural member may be exposed on an outer surface of the implant. Further, the central member curve may include a winding segment, and the winding segment of the central member curve may wind around a fixed path extending from the first portion of the body to the second portion of the body. Also, the central member curve may make one or more full turns around the fixed path. And, the structural member may have a member diameter at the winding segment, wherein the winding segment has a winding diameter corresponding with the full turn around the fixed path and the member diameter is greater than the winding diameter.
