A bone insert includes a cap having a convex top surface, an elongated stem, and a barrier between the cap and the stem. The stem of the bone insert is inserted into a hole formed in a host bone until the barrier is pressed against the exposed bone. The bone implant can be placed against a small focus contact point on the cap. Liquid cement can be injected into a space volume between the host bone and a bone implant. The cap can be made of a material and/or have surface features that create a strong bond with the cement when the liquid cement cures. The stem can be made of a material and/or have bone ingrowth surface features that create a strong bond with the bone.

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment.

Augments for implantation of an orthopedic implant device in a bone. A distal end of an outer portion of the augment can have a shape that is configured to generally conform to the shape of a metaphyseal-diaphyseal junction of an intramedullary canal of the bone. Further, a proximal end of the outer portion of the augment has a shape that is configured to generally conform to a shape of the metaphyseal region of the intramedullary canal. Additionally, the shape of the outer portion at the distal end can be separated from the shape of the outer portion at the proximal end by a distance that is approximately equal to the distance between the metaphyseal-diaphyseal junction and the metaphyseal region of the intramedullary canal.

An assembly for making an intramedullary spacer made of medical cement, designed to be inserted in a medullary canal. The assembly includes comprising a stem module and a reinforcing core. The stem module includes an end wall delimiting below a stem moulding chamber (SMC); and wherein the reinforcing core is at least partly positioned in the stem moulding chamber (SMC).
