Disclosed herein is a temporary knee spacer system for the temporary replacement of a knee joint, which is designed for the interim phase of two-stage septic revisions of knee joint total endoprostheses. The knee spacer system can be used in particular with two-phase septic revisions with which two or more microbial germs are the cause of an infection of the knee joint total endoprosthesis and the surrounding tissue.

A cup and a temporary insert are respectively configured to be tightly press fitted into each other along their periphery. The temporary insert includes a through hole communicating outside with a free space between the outer surface of the temporary insert and the inner surface of the cup. In the through hole can be engaged the threaded end of an impactor, for manipulating the cup when it is being set. A syringe can be engaged, enabling a liquid under pressure to be injected into the free space, thus separating the temporary insert from the cup without any risk of damaging the inner surface of the cup. Thus, the cup can be securely manipulated when it is being set without any risk of damaging the inner surface of the cup.

A spacer mold and method for producing a hip spacer, the spacer mold comprises a base element (1), in which a hollow mold is provided as negative image of one side of a femoral stem of the spacer to be generated, whereby a recess connected to the hollow mold is arranged on the proximal end of the hollow mold in the base element. The spacer mold further comprises a semi-spherical insert (2) comprising a femoral head mold as negative image of one side of a femoral head of the spacer to be generated, whereby the semi-spherical insert (2) is to be arranged in the recess in the base element (1). Further, the spacer mold comprises an adapter insert (3) that is designed as a hollow body that is open on two sides and that is or can be arranged in the recess of the base element (1) between the semi-spherical insert (2) and the hollow mold such that the recess exerts a pressure onto the adapter insert (3) and the semi-spherical insert (2). Moreover, the spacer mold comprises a punch (4) that comprises a punch hollow mold in the form of the negative image of the remaining femoral stem and that is arranged on or can be pressed onto the top side of the base element (1).

An orthopedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.

A problem with total disc implant surgery appears to be the positioning of the implant which if not correct may lead to pain and eventually new surgery. The present invention relates to an improved disc implant for total disc replacement, that includes two inter-vertebral elements which are flexibly connected via a coupling mechanism. Following surgery, the relative movability of the two inter-vertebral elements is decreased overtime, as bone ingrowth occurring around the implant and specifically through osseointegrative sections gradually decrease the movability of the elements relative to each other. Following, the relative movability of the implant elements is replaced by fixation of the elements. The fixation has flowingly occurred in a position affected by the movement of the patient, and is thereby more acceptable to the patient.

An orthopedic implant includes an internal fixation device. The internal fixation device includes: an exterior surface; a threaded section including a reservoir and at least one threaded section channel fluidly communicating the reservoir with the exterior surface, each threaded section channel having an interior diameter and a length which is greater than the interior diameter; a head including a head channel fluidly communicating the reservoir with an exterior surface of the head, a channel diameter of the head channel being respectively larger than a largest interior diameter of each threaded section channel, the channel diameter of the head channel being the same as a large interior diameter of the reservoir; and a continuously tapering inner surface between the head channel and the reservoir.
