摘要： An artificial head assembly for a human femur consists of the head portionroper and a metal pin. The head portion is a sintered ceramic ball having a polished contact face of convex, spherical curvature and a blind bore tapering conically inward toward the contact face. The pin is shaped for insertion of one end into the hollow stump of the femur, the other end tapering conically at the same apex angle as the bore in the ball. A knurling of the conical face of the pin reduces the compressive strength of the pin surface to less than the tensile strength of the ball so that the assembled head and pin can be sterilized without cracking the ceramic head portion because of differences in coefficients of thermal expansion between the metal and the ceramic material.

摘要： An intermediate member is positioned between the proximal joint part and the distal joint part in order to permit increased hand movements. The intermediate member has a V-shaped recess which receives an extension of the proximal joint part and allows an extra degree of movement. The distal joint part has a spherical joint head which is snapped into a socket in the intermediate member.

摘要： The stem of the femoral prosthesis is provided with a slot in the medial narrow side which communicates with a through-bore within the stem adjacent to the collar. In addition, an elastomeric filling is disposed within the through-bore and cooperates with an arch which connects the proximal end of the stem to the collar or neck in order to adapt the resilience of the stem in the proximal zone to the resilience of the cortical bone. The filling may be made of polyurethane or silicone material.

摘要： The stem of the endoprosthesis comprises a core which provides the necessary strength to the endoprosthesis and a jacket or sleeve of thermoplastic having a softening temperature below 60.degree. C. The jacket can be made flowable upon heating so that during implantation, the jacket can be adapted to the bone cavity. In addition, the jacket can be heated at any subsequent time to return to a plastically deformable state in order to facilitate re-operations.

摘要： The stem of the prosthesis is fixed in a medullated bone by means of a plurality of spacers which are distributed over the length of the stem. The spacers serve to stabilize the stem over the entire length of the stem within the bone cavity. Bone cement is charged into each peripheral opening defined between a pair of spacers via bores drilled transversely through the cortex of the bone in stages from the distal end toward the proximal end.

摘要： The reinforcement is formed of a peg from which a plurality of flaps extend with slots formed between adjacent flaps. The flaps serve to separate a bone cement bed within the interior of the reinforcement from a layer of a compacted spongy tissue externally of the reinforcement. The slots between the flaps extend over the entire height of the reinforcement and permit substantial spreading or widening of the flaps radially in order to adapt to the individual operation cavity and to anchoring stems of different cross-sectional sizes and shapes.

摘要： The hip joint acetabulum uses a synthetic ring for snap-fitting the acetabulum body within the outer bowl. The ring is slit to provide for the snap fit connection and is provided with an annular lug which projects into an annular groove within the outer bowl. Recesses are also provided to permit a tool to penetrate into the acetabulum to separate the lug from the remainder of the ring to permit ready detachment of the body from the bowl.

摘要： The external surface of the hip joint socket is provided with a contrast ring in a diametric plane of the joint head receiving cavity as well as with a metallic measuring ring in the upper surface of the socket body. The measuring ring is concentric to the axis of rotation of the body and is parallel to the plane of the contrast ring. By measuring the distance of the two metallic rings from each other in an X-ray picture, a determination can be made as to whether a displacement of the center of the spherical joint head is due in part to a cold flow of the socket material or exclusively to abrasion.
