摘要： An implant for a hip or other joint is provided. Briefly stated, an intramedullary stem is provided having flexibility which is comparable to that of the surrounding bone. A bore is disposed in the stem portion with the stem wall thickness uniform or varying from the proximal end to the distal end, depending upon the amount of flexibility desired. This flexibility therefore distributes the loading forces from the joint more uniformly over the supporting cortical bone with the result that bone degeneration from stress shielding is minimized or eliminated.

摘要： A joint prosthesis comprising two co-operating prosthesis members fastening each to a different joint bone. At least one of the prosthesis members is formed by at least two prosthesis elements one surrounding the other, the one prosthesis element adjacent the bone being provided with fastening means distributed along the outer face and being located inside the outer face when the joint prosthesis is being applied, out of which outer face they can subsequently be moved in order to cause them to penetrate into the bone.The fastening means are formed by pins guided in passages of the prosthesis element. The tipform of these pins could be chosen in relation to the hardness of the bone to be penetrated.Furthermore, the contact faces of the two prosthesis elements could be provided with coating mimicing the elastic and/or resilient features of bone.

摘要： A modular hip stem prosthesis including a hip stem with an integral, enlarged shoulder and a neck section mountable to the hip stem. The integral, enlarged shoulder is designed to closely conform to the metaphyseal region to securely mount the hip stem in the end of the femur. The enlarged, shoulder portion of the hip stem is also selectively configured to be fabricated as a separate element so as to allow one of a plurality of distal stems to be mounted to the enlarged shoulder to create the hip stem. The neck section readily adapts the hip stem prosthesis for repair and replacement of the components of the total hip replacement without requiring replacement of the hip stem.

摘要： The bone implant for prostheses, particularly joints or joint members, preferably joints of the human locomotor system and especially the walking system, contains a shaft insertable into a cavity in a bone. The shaft has a total cross-section increasing from its diaphysis-associated distal end to its metaphysis-associated proximal end. Preferably, The shaft possesses in the region of the metaphysis-associated proximal end an integrally formed or separate intermediate piece at which the joint or joint member can be arranged. The shaft is preferably immediately and securely anchored in the bone and particularly is made of a metallic material. The shaft possesses an oblong rotationally symmetrical shaft body having an outer surface generated by, if desired, a longitudinally curved or preferably a substantially straight generatrix. The shaft body substantially has the shape of a truncated cone. Its outer surface can be contracted with the bone without the presence of a bonding agent and possesses a plurality of projections extending substantially parallel to the generatrix generating the outer surface. The projections preferably extend along the total length of the shaft body and are preferably mutually similar. The projections have edges extending preferably radially outwardly from the main axis of the shaft body, and preferably have the form of a knife edge.

摘要： An endoprosthesis for the hip joint includes a head portion, or artificial femoral head, and a substantially elbow-shaped member of polyethylene resiliently supporting said head portion. The elbow-shaped member includes a relatively short upper portion and a relatively long lower portion and defines at the junction of these two portions on one side a concave bent and on the other side a convex bent. Each of both portions is provided with an internal channel. One of these channels is substantially coaxial with the upper portion of said elbow-shaped member and has an entrance or opening situated at the convex bent of said elbowshaped member. The other of these channels is substantially coaxial with said lower portion of said elbow-shaped member and has an entrance or opening situated at the upper portion of said elbow-shaped member. The aforementioned channels intersect at an obtuse angle and each of the aforementioned channels receives one of a pair of pins or studs. The upper head portion or artificial femoral head defines a slanting channel into which said upper portion of said elbow-shaped member of polyethylene projects.

摘要： A cementless femoral stem prosthesis for use in hip replacement surgery is disclosed. The stem has a collar and a body having a fixed end and a shank end. The shank end is divided into a pair of adjustable endosteal plates that are secured to the cortical bone of the femur by screws. The present invention provides an improved femoral stem structure because the screws through the endosteal plates transfer the load to the cortical bone rather than the cancellous bone, the medial endosteal plate has a plurality of spurs to engage with the cancellous bone to increase the number of stress-strain points, and the collar transfers the load directly to the cortical bone. All of these features work in tandem to reduce the risk of stress shielding, bone resorption, prosthetic loosening, and other difficulties associated with femoral stem prostheses.
