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 femoral hip joint spacer. The spacer has a prosthesis body with a ball head, a neck, a stem and an anchoring sleeve which encloses the stem on a proximal side of the stem with a circumferential fastening area, irrigation liquid inlet and outlet openings in the body surface, at least one irrigation liquid discharge opening on a distal side of the stem and at least one irrigation liquid intake opening on the ball head or on the neck. The discharge opening is connected in a liquid-permeable manner to the inlet opening but not to the outlet opening and the intake opening is connected inside the prothesis body in a liquid-permeable manner to the outlet opening but not to the inlet opening. A cavity open on two sides is formed inside the anchoring sleeve and connects a proximal side to a distal side of the sleeve in a liquid-permeable manner.

A method of denuding bone stock with a denuder, such as a bone stock denuder container, is disclosed. The bone stock is deposited into a wash chamber formed with a curved chamber wall. The bone stock is impacted with a stream of fluid under pressure to separate non-bone tissue from bone. Fluid and non-bone tissue are drained from the wash chamber.

A denuder, such as a bone stock denuder container, is disclosed. The denuder includes a nozzle and a container body. The nozzle is configured to be fluidically coupled to a source of fluid and to direct a fluid stream. The container body includes curved chamber wall that forms a wash chamber. The wash chamber is configured to receive a bone stock. The nozzle is configured to direct the fluid stream to impact the curved chamber wall.

A femoral hip joint spacer including a prosthesis body having a ball head with a sliding surface, a neck, a collar and a stem. A fastening area is arranged on the stem. The femoral hip joint spacer further has a first connector for feeding a medical irrigation liquid into the body, a second connector for draining the irrigation liquid from the body, and an irrigation liquid inlet opening. The first connector is connected in a liquid-conveying manner to the irrigation liquid inlet opening and an irrigation liquid outlet opening. The second connector is connected in a liquid-conveying manner to the irrigation liquid outlet opening, an irrigation liquid discharge opening and an irrigation liquid intake opening. The irrigation liquid discharge opening is connected inside the body to the irrigation liquid inlet opening and the irrigation liquid intake opening is connected inside the body to the irrigation liquid outlet opening.

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 device for the drying of tooth or bone surfaces includes a radiation source for irradiating the tooth or bone surface to be dried, a temperature sensor and/or a humidity sensor.

A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.
