A medical implant includes a body and a porous structure attached to the body. A boss integral with the body extends outwardly from a surface of the body. The porous structure has a surface that cooperates with the boss of the body to prevent pullout of the body from the porous structure. In fabricating the medical implant, the body and the porous structure are formed separately and subsequently secured together.

The present disclosure provides alert implants that comprise a medical device and an implantable reporting processor (IRP), where one example of such a medical device includes a component for a total knee arthroplasty (TKA) such as a tibial extension, a femoral component for hip replacements, a breast implant, a distal rod for arm or leg breakage repair, a scoliosis rod, a dynamic hip screw, a spinal interbody spacer, and tooling and methods that may be used to form the alert implant, and uses of such alert implants in the health maintenance of patients who receive the implant.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

A femur plate is provided, the femur plate comprising a first end portion anatomically pre-formed to conform to a trochanter region of the femur and a second end portion anatomically pre-formed to conform to a condyle region of the femur, wherein the second end portion comprises at least one first opening configured to receive a bone fastener. The femur plate further comprises an elongate shaft extending from the first end portion to the second end portion, the elongate shaft comprising at least one second opening configured to receive a bone fastener. Furthermore, a periprosthetic implant system comprising the femur plate and a method of implanting the femur plate are provided.

A support apparatus for supporting an end of a distraction marrow nail includes a base plate attachable to the pelvis, and a mounting device on the base plate for mounting of the support end of the distraction marrow nail. The mounting device includes a ball seat having a cavity forming a ball seat surface for mounting a ball on the support end of the distraction marrow nail, wherein the inside radius of the ball seat surface corresponds to the outside radius of the ball, and wherein the ball seat is arranged so that the ball of the distraction marrow nail can be movably mounted such that the distraction marrow nail can perform a movement sufficient for an extensively normal movement pattern of a femur and cannot luxate out of the ball seat when implanted in the femur.

A method for implantation of non-spherical, asymmetric implants is provided that includes devising a pre-surgical plan with pre-operative planning software operating on a computer to define at least one of shape, orientation, type, size, geometry, or placement of the non-spherical, asymmetric implant in an operative bone of a subject. A computer assisted surgical device is used to place the non-spherical, asymmetric implant. The implant is positioned within the bone by the computer assisted surgical device in accordance with pre-surgical plan. A non-spherical, asymmetric implant for insertion in a bone formed of separate stem, neck, and head portions and suitable for implantation by the method is also disclosed.

In the present disclosure, an artificial joint stem includes a base having an outer surface including a rough surface, and a coating film disposed on the rough surface of the base and containing a calcium phosphate-based material and an antimicrobial agent. The rough surface includes an exposed region exposed from the coating film.
