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.

An additive manufacturing (AM) device for biomaterials comprises a reservoir, a shaft, and a material delivery head. The device can be used for intracorporeal additive manufacturing. Material within the reservoir can be expelled by a mechanical transmission element, for example a syringe pump, a peristaltic pump, an air pressure pump, or a hydraulic pressure pump. The reservoir can be a barrel, a cartridge, or a cassette. The reservoir can narrow into the shaft, and the shaft can terminate into the nozzle. The shaft can house an inner tube. The device can have an actuator joint capable of being mechanically linked to a robotic surgical system. The actuator joint can have a motor that drives the mechanical transmission element.

Method for manufacturing a bone pin for connection to a bone, particularly for fixing an implant to a bone, the bone pin having an implant contacting part arranged to contact the implant in connected situation and a bone contacting part arranged to engage the bone in connected situation, wherein the method comprises the steps of:—providing bone information which is indicative for the bone which the bone contacting part is arranged to engage;—providing a bone contacting part which is customized on the basis of the bone information for engaging said bone;—providing an implant contacting part; and—assembling the bone contacting part and the implant contacting part for manufacturing the pin.

A hip prosthesis includes an acetabular cup and a femoral component comprising a head and a stem, wherein the stem comprises a truss structure, the truss structure comprising a space truss comprising a plurality of planar truss units having a plurality of struts joined at nodes, wherein the web structure is configured to interface with bone tissue.

Provided is a method for forming an implant with an autonomous manufacturing device. The method includes accessing a first computer-readable reconstruction of a being's anatomy; accessing a second computer-readable reconstruction of an implant; accessing a third computer-readable reconstruction comprising the first computer-readable reconstruction superimposed with the second computer readable reconstruction; generating at least one computer-readable trace from a point cloud; and forming an implant with an autonomous manufacturing device, wherein the autonomous manufacturing device forms the implant into a shape defined by at least one dimension of the computer-readable trace.

A method for growing a channeled spinal implant in situ, using a surgical additive-manufacturing system having a dispensing component, and implants formed thereby. The method can include positioning the dispensing component at least partially within an interbody space, between a first patient vertebra and a second patient vertebra, and maneuvering, in an applying step, the dispensing component within the interbody space and depositing, by the dispensing component, printing material on or adjacent the first vertebra. The applying step includes maneuvering the dispensing component and applying the printing material selectively to form an outer surface of the implant having a channel opening and to form an interior of the implant having at least one elongate channel extending to the opening.

Osteoconductive devices and methods of use are provided herein. An example device includes a hollow body member having surfaces, the hollow body member having a shape that substantially conforms to a cross-sectional area of an opening of an orthopedic prosthesis, and apertures formed in the surfaces of the hollow body member that provide a osteoconductive path through the hollow body member.

A spinal implant device is provided comprising a body structure with a central cavity and a movable lid configured to cover the central cavity. The movable lid is configured to be opened to pack a material in the central cavity. The movable lid can be connected to the body structure with a moveable joint. The spinal implant device can include a compressible feature. A method for treating the spine is provided comprising opening a movable lid of a spinal implant device, packing a material in a central cavity of a spinal implant device, closing the movable lid, and inserting the spinal implant device between vertebrae.

A scaffold (12) for tissue engineering comprises an inner portion (14), an outer portion (16), and a base portion (22) connecting the inner portion and the outer portion. The inner portion (14) comprises a channel (18) surrounded by a first set of one or more walls. The outer portion (16) comprises a second set of one or more walls. The portions are arranged such that the second set of one or more walls substantially surrounds the first set of one or more walls with a spacing between the first and second sets of walls defining a cavity (20) between the inner portion (14) and the outer portion (16). The inner portion (14) and the outer portion (16) may have different shapes; and/or the scaffold (12) may further comprise a filler material in the cavity (20) defined between the inner and outer portions.

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.
