Described is a mould (1) for making a temporary prosthetic component for a knee in an operating room comprising: a first half-mould (10); a second half-mould (20) which can be coupled to the first half-mould (10) for forming a moulding chamber (C) for a temporary prosthetic component made of medical cement; and elements (30) for fixing the first half-mould (10) to the second half-mould (20).

Each fixing element (30) has a rod (31) configured for connecting the first half-mould (10) to the second half-mould (20) and defining a weakness neck (32) configured to allow a facilitated breakage of the rod (31).

A bone cement mold for a bone cement spacer, the bone cement mold including: a first mold component defining a first cavity shaped to form at least a majority of a head portion of the spacer; a second mold component defining a second cavity shaped to form a first part of a stem portion of the spacer; a third mold component defining a third cavity shaped to form a second part of the stem portion of the spacer; the second mold component and the third mold component combining to define a cavity shaped to form at least a majority of the stem portion; an abutting combination of the first mold component, second mold component, and third component defining a communicative cavity shaped to form the head portion integrally connected with the stem portion. Bone cement spacers formed from the bone cement mold, and computer methods and systems for selecting and operating the bone cement mold are also described.

A surgical implant, which in use, provides a barrier between layers of tissue such that tissue on one side of the implant does not adhere to tissue on the other side, the improvement comprising that the implant is made of suitably anatomically shaped surgically acceptable sheet material.

Disposable temporary spacer device for an articulation of the human body or for a bone cavity, wherein the spacer device includes at least one first component adapted to be constrained to a bone portion or end, wherein the spacer device is made from a biologically compatible material and comprises interconnected pores distributed in the entire volume occupied by the spacer device, in which the interconnected pores have a size and occupy a percentage of the volume of the spacer device such that it is able to absorb and consequently elute one or more pharmaceutical or medical substances in liquid or fluid form or in paste, cream, gel, wax, or viscous form.

A reconfigurable orthopedic implant trial comprising: (a) a first orthopedic component; (b) a second orthopedic component that includes a second sensor on a second articulating surface thereof, the second orthopedic component configured to removably mount to the first orthopedic component; (c) a third orthopedic component that includes a third sensor on a third articulating surface thereof, the third orthopedic component configured to removably mount to the first orthopedic component, where the second sensor and the third sensor are configured to generate kinematic data.

A modular bone model can include a bone component and an implant component that can be positioned on the bone component. The implant component can be shaped and sized to correspond to a head component of a medical implant to simulate an articulating surface of the head component. Similarly, the bone component can be shaped to simulate a natural bone to which the medical implant can be mounted. Alternatively, the head component of the medical implant can be mounted directly to the bone component to simulate the mounting on the natural bone.

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.

An apparatus and method are provided for a syndesmosis treatment construct configured to be placed into a cinched configuration that presses a first bone against a second bone. The syndesmosis treatment construct comprises a proximal fixator to contact the first bone and a distal fixator to contact the second bone. A first suture and a second suture are parallelly looped through the proximal fixator and oppositely looped through the distal fixator. Distal ends of the first and second sutures are fixated within a washer disposed between the proximal fixator and the first bone. Proximal ends of the first and second sutures are passed through openings in the washer and through the proximal fixator. Pulling of the proximal ends by a practitioner places the syndesmosis treatment construct into a cinched configuration. Any of various suitable suture knots may be formed so as to fixate the cinched configuration.

A cement mold assembly configured to form a temporary implant for use in delivering antibiotics to an infected site can includes a first mold and a second mold. The first mold can have an open end and an inner wall. The first mold can define a tibial component forming cavity including a platform forming cavity and a stem forming cavity. The second mold can have a body portion configured to be slidably and progressively receivable by the inner wall into the tibial component forming cavity in a direction toward the closed end. Progressive advancement of the second mold into the tibial component forming cavity urges cement within the tibial component forming cavity against the body portion and the inner wall to form a unitary tibial component having a tibial tray portion formed by the platform forming cavity and a stem portion formed by the stem forming cavity.

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.
