Methods and apparatus for treating disc herniation provide a conformable device which assumes a first shape associated with insertion and a second shape or expanded shape to occlude the defect which typically follows partial discectomy. The device may take different forms according to the invention, including patches size to cover the defect or plugs adapted to fill the defect. In a preferred embodiment, however, the device is a gel or other liquid or semi-liquid which solidifies to occlude the defect from within the body of the disc itself. In another preferred embodiment, a mesh screen is collapsed into an elongated form for the purposes of insertion, thereby minimizing the size of the requisite incision while avoiding delicate surrounding nerves. Such a configuration also permits the use of instrumentation to install the device, including, for example, a hollow tube or sheath adapted to hold the collapsed screen, and a push rod to expel the collapsed device out of the sheath for use in occluding the disc defect. A device according to the invention may further include one or more anchors to assist in permanently affixing the device with respect to the defect.

Described is a device (1) for making a tibial spacer (10) for a temporary knee prosthesis made of medical cement, comprising: a tibial plate module (2), defining a first moulding chamber (MC1) configured for making a tibial plate (20), a stem module (3), defining a second moulding chamber (MC2) configured for making at least partly a tibial stem (30) designed to be inserted in a tibial channel; wherein the first moulding chamber (MC1) and the second moulding chamber (MC2) are fluid dynamically communicating, to allow a tibial spacer (10) to be made in a single body.

Described is an assembly (100) for making a tibial spacer (10) of a temporary knee prosthesis comprising the device (1) and a reinforcing core (40) which can be positioned at least partly inside the second moulding chamber (MC2) of the device (1).

A system of prosthetic implants for a total knee replacement procedure is provided. The system includes a tibial component of a knee joint implant, a tibial insert configured to be positioned against the superior side of the platform of the tibial component, a first femoral component of a knee joint implant, and a second femoral component of a knee joint implant.

A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.

The invention relates to a casting mold for producing a hip joint spacer, which comprises a head element comprising an upper shell and a lower shell, optionally a neck element, and a stem element, which comprises an upper shell and a lower shell, wherein the casting mold has a latching element, and an upper shell and a lower shell of the head element and/or of the stem element can be connected to one another by means of the latching element.
