Embodiments of forming custom interbody implants that may be used to stabilize region(s) formed between mammalian bony segments, including systems and methods to produce a custom interbody element that may be used to stabilize or couple region(s) formed between two or more mammalian bony segments. Other embodiments may be described and claimed.

This disclosure relates to orthopaedic implants and methods for restoring functionality to a joint. The implants described herein may be utilized during orthopaedic procedures and may be incorporated into a shoulder prosthesis for restoring functionality to shoulders having advanced cartilage disease. The disclosed implants may incorporate one or more fasteners formed together with a main body of the respective implant at a breakable connection. The fastener may be deployed during a surgical procedure, which may improve fixation of the implant at the surgical site.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

An implant may include a body having a first blade having a first retracted position in the body and a first extended position where the first blade extends outwardly from the body, a second extendable blade, and a blade actuating member configured to translate through the body in directions parallel to the lateral axis. When the blade actuating member is moved in a first direction along the lateral axis, the first blade moves towards the first extended position; and in the first extended position, the first blade extends from the superior surface at a first non-zero angle with respect to the superior-inferior axis; and the second blade moves towards a second extended position in which the second blade extends from the inferior surface at a second non-zero angle with respect to the superior-inferior axis.

The disclosed subject matter relates to a system and method for preparing a surface of a bone proximate a joint, in which the preparation includes boring a plurality of arced channels/troughs in the bone surface using an arch drill assembly guided by plural guide bores along a predetermined longitudinal arc. The bored troughs create a scalloped surface on the bone to which an inverse contoured joint insert/implant having cooperating convex ridges engages. The plural guide bores are also defined by the predetermined longitudinal arc which may be circular or helical. The disclosed subject matter minimizes bone removal and allows greater access options for preparing the bone surface.

Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

Embodiments may include an attachable fastener, which may include a bondable material that may be secured to the end of an end effector. Vibration may be tuned to occur at a distal end of the fastener. Accordingly, the fastener may be used to generate heat at a distal point of contact. If the contact surface contains bondable material, that material may be softened. If the fastener includes bondable material at the point of contact, that material may also be softened by heat produced by vibration at the contact area. A hard implant or another polymeric material may function as the anvil.

A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed therebetween. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.

Improved osseointegration devices and structures, including such structures that can be used in connection with prosthetic limbs. Examples include a self-centering implant/nut configuration, a centering device, a tapered mounting screw hole, a coupling device, and an aiming device. The devices are highly efficacious. For example, they can be secured with minimal residual bone, and may be removed without significant bone destruction.

A bone implant includes a main body in the form of a hollow body open on both sides in the axial direction. The main body includes a load-bearing material. An encasing body at least partially encases the main body on the outside and includes an in vivo degradable/in vivo resorbable material. Alternatively, the encasing body includes a multiplicity of shaped bodies protruding from the main body in the radial direction that include an in vivo degradable/in vivo resorbable material. A method for producing the bone implant includes an additive manufacturing process. The main body can be at least partially encased by the encasing body in the additive manufacturing process.
