The prosthesis is composed of a femoral head base, a femoral head post, a long femoral stem, a cement canal along its longitudinal axis, a spacer, a collar, and a distal restrictor. The prosthesis is placed into the prepared medullary canal. With collar in position, a bone cement injector is readily threaded on to the proximal portion of the cement canal. Cement is injected and subsequently travels down through the canal, through the spacer, and eventually exits openings at the bottom of the spacer. The distal restrictor plug halts downward cement travel, thus initiating an upward, retrograde filling of the void in between the prosthesis and the cancellous bone wall. The cement reaches the collar or cement restrictor, thus proximally dislodging all air bubbles, blood, and blood products.

Device for filling bone cavities with fluid cement, acetabular cavities in particular

The device (1) for filling bone cavities with fluid cement, acetabular cavities in particular, comprises a transfer channel (2) for transferring a fluid cement (F) with a first opening (3) which can be associated to a dispenser instrument (5) for dispensing the fluid cement and a second opening (4) through which the fluid cement exits, and that is associated to an applicator element (6) of the fluid to a bone cavity. The applicator element has a useful dispensing surface that is larger than the transfer channel and comprises a substantially plate-like body whose main opposite surfaces define a first side (7) for connecting to the transfer channel and a second side (8) for the application of the fluid cement. Furthermore, the second side has a containing border (9) of the fluid cement which can be positioned in contact against the edge of the bone cavity and which comprises a perimeter turned-up edge of the plate-like body which extends crosswise from the body itself.

Device for sealing-off medullary canals

Die Erfindung betrifft eine Vorrichtung zum Abdichten der Markhöhle eines Knochens bei der Applikation von Knochenzement. Die Vorrichtung weist ein elastisches Unterteil (10) zum formschlüssigen Kontakt mit dem Knochen um die Markhöhle herum und ein starres Oberteil (30) auf. Wenn die Knochenzementkartusche (40) nach unten gedrückt wird, preßt das starre Oberteil (30) das Unterteil (10) gegen den Knochen, und die Markhöhle wird vakuumdicht abgedichtet. Mit der erfindungsgemäßen Vorrichtung wird eine Auffüllung der Markhöhle mit Knochenzement unter Vakuum bei gleichzeitiger Drainage erleichtert.

Apparatus and method for addressing femoral acetabular impingement

An implant for treating a rim deformity of an acetabulum comprises an implant generally having an L-shaped profile in the anterior posterior coronal view. The implant has a first flange and a second flange. The first flange is configured to extend into the acetabulum and the second flange is configured generally perpendicular to the first flange to extend over the rim of the acetabulum. A fixation element is configured to extend through the second flange and fix the implant to chondral bone.

Orthopaedic fixation assembly, system, and method of use

An orthopaedic fixation assembly for prosthetic biologic attachment. The orthopaedic fixation assembly may include a main body with a longitudinally-extending stem having a proximal end, a distal end, and a cavity body. An anchor plug may be configured to be received within the stem cavity, and securable thereto via complementary mating surfaces. A spindle structure may be fixedly attached to the proximal end of the longitudinally-extending stem and protrude outwardly therefrom such that a portion of the structure extends externally beyond the resected cavity of the bone that may prevent rotational motion of the spindle. The spindle structure may have at least one compliant biasing member configured to apply a compressive force to the surrounding bone. A porous coating may be at the juncture between stem and spindle structure, on the spindle, and the splines and anti-rotation chocks, improving the initial stability of the implant and facilitating long-term bone ingrowth.

Interpositioning collar for the stem of a metal prosthetic bone implant

ABSTRACT OF THE DISCLOSURE Metal prosthetic devices having stems implantable in bone are known, the stem of each such device extending from a collar surface designed to bear against the cut surface of the bone. In this invention, an interpositioning collar made from a material having a low modulus of elasticity is provided which can be fitted onto the stem and be partially implanted therewith to improve the joint between the cut bone surface and the collar sur-face of the prosthetic device, as well as the joint between the im-planted stem and the adjacent bone portions. The interpositioning collar consists of a flat elongated, lengthwise tapered collar element which may be either O-shaped or U-shaped and a flange which is U-shaped and extends perpendicularly from the lower face of the collar element. In use, the collar element and flange em-brace the implanted stem of the prosthetic device, the collar ele-ment lying immediately below the collar of the prosthetic device and flat on the cut surface of the bone, with the flange extend ing into the bone alongside a topmost portion of the stem.

Implant replacing the greater trochanter

An artificial muscle attachment element (8) with bores (9) is provided for fixation of the muscles and ligaments as replacement for the greater trochanter. This muscle attachment element (8) is arranged so as to be laterally offset relative to the stem (1) of the associated femoral head prosthesis and is retained and borne by the prosthesis. <IMAGE>

Centering device for femoral implant and apparatus for implementation thereof

A method and apparatus for centering the stem of a femoral hip prosthesis in the cavity formed in the medullary canal in the proximal end of the femur. The apparatus includes a sleeve or other like device which is mounted onto the neck of the femoral hip prosthesis and which contains at least two projections extending from a lower surface thereof which are adapted to seat in correspondingly formed slots disposed on the upper proximal surface of the femur bone. The slots are positioned such that when the projections reside therein, the stem is centered within the cavity. The slots and projections are elongated in a direction generally transverse to the direction of elongation of the stem, and in this direction of elongation each slot and associated projection is not parallel to the other slot and associated projection. The device of this invention may be used either with prosthesis having a collar, or with a collarless prosthesis. The method of this invention includes the step of mounting a sleeve or other like device on the neck of a femoral hip prosthesis and inserting projections on the device into previously formed slots disposed on the upper proximal surface of the femur bone.
