A humeral implant component connectable to another humeral implant component, the humeral implant component comprising: a longitudinal axis, a first end and a second end, the first end and the second end opposing each other along the longitudinal axis of the humeral implant component, and an interface part for connecting the humeral implant component to the other humeral implant component, wherein the interface part is tapered along the longitudinal axis in a direction from the second end to the first end, the interface part being engageable with a tapered interface part of the other humeral implant component to form a tapered connection between the humeral implant component and the other humeral implant component, wherein the humeral implant component further comprises a through hole extending along the longitudinal axis for locking the tapered connection by a longitudinal fastener.

An orthopedic system for delivery of a therapeutic agent to a bone includes an elongate stem adapted to be inserted into an intramedullary canal, an inlet configured to receive the therapeutic agent, and one or more outlets configured to deliver the therapeutic agent to the bone. The elongate stem may comprise one or more protrusions to engage the bone, and one or more channels extending longitudinally therein, fluidly coupled to the inlet. The therapeutic agent flows from the inlet through the one or more channels and exits into the intramedullary canal through the one or more outlets. The system may be configured to allow one or more dimensions of the system to be adjusted to accommodate the anatomy of a patient.

The present disclosure provides an implant component assembly for a joint replacement. The assembly comprises an implant component, the implant component including an interface part for attaching another implant component and an assembly channel. The assembly further comprises an assembly screw for securing the other implant component to the implant component, the assembly screw having a longitudinal axis, a screw head, and a screw shank and being insertable into the assembly channel. A screw retention unit of the assembly is configured for keeping the assembly screw within the assembly channel and allowing rotation of the assembly screw about the longitudinal axis.

An antibiotic delivery system including an intramedullary stem that is adapted to be removably mounted into a medullary canal of a bone. The stem includes a body having an inlet adapted to be in fluid communication with a source of liquid-borne antibiotic and a plurality of outlets disposed along the stem. A channel extends between the inlet and the plurality of outlets for delivering a fluid-borne antibiotic from the inlet to the plurality of outlets so as to distribute the antibiotic along the medullary canal in a controlled fashion. A method of treating an infected joint during a two-stage re-implantation of an orthopedic implant is also disclosed.

A ceramic component to be securely connected to an additional component in force-locked manner. A joint prosthesis comprising a ceramic sphere (1), a metallic sleeve (2) and a base plate (3) with a cylindrical projection. The connection between the ceramic sphere and the base plate or shaft (7) is secured by a screw (6).

In an artificial joint that includes a head assembly attached by taper fit to a proximal portion of a surgically implanted stem, it may become necessary to surgically remove the head assembly. A puller can simultaneously apply a force distally to a non-peripheral portion of a proximal side of the head assembly and proximally to several locations spaced apart around a circumference of the distal side of the head assembly. In some examples, the proximal side of the head assembly includes a plug disposed at the non-peripheral portion. The puller can force the plug into contact with the proximal end of the stem, then apply the distal force through the plug to the stem. In other examples lacking a plug, the non-peripheral portion of the head can deform or break in response to the applied distal force, so that the distal force can apply to the stem.

A spacer device for the two-step treatment of prosthesis infections, made from biologically compatible and porous material designed to allow the possibility of adding pharmaceutical products, active and/or therapeutic ingredients, includes a first portion designed to be fixed to a corresponding bone bed remaining from a previous implant, and a second portion designed to be inserted in a corresponding articular area of the patient, the first portion and the second portion being attached by adjustable connecting means.

An assembly for attachment to a first implant component has a size and shape of a second implant component to be implanted together with the first implant component. The assembly includes a first body including a plug having a projection, and a second body including a recess having an internal surface defining at least one indentation. In a temporary configuration, when the plug is disposed within the recess and the projection is disposed at least partially within one of the at least one indentations, the first and second bodies are removably connected such that the first and second bodies are prevented from separating. A method of assembling the assembly includes removably connecting the plug of the first body into the recess of the second body by locating the projection within an indentation, such that the bodies are prevented from separating, and positioning the assembly on the first implant component.

A hip prosthesis head includes: an external element with a convex external surface, and an internal element having a truncated-conical seat; wherein the external element and the internal element are made of different materials; the internal element is coupled in a blind hole of the external element in fit-in coupling mode; the external element has an annular base around the blind hole, and the internal element has a truncated-conical body that is open on the bottom, and an annular base that protrudes radially outwards from a lower edge of the body in order to be in contact with the base of the external element.
