摘要： A femur head cap for endoprosthesis possessing a spherical shape and having a recess for partially receiving the femur head, the recess being open toward the neck of the femur. The cap is advantageous in that it can be firmly anchored to avoid rotation and tilting without the use of bone cement and further allows for simple resection to be performed so that supply of blood to the bone is not impaired.

摘要： A knee joint prosthesis includes a C-shaped femur cap to be fitted onto a resected femur condyle. The C-shaped femur cap is made up of two arch-shaped parts spaced apart and connected by a relatively flat third part. Each of the arch-shaped parts has a different radius. The arch-shaped part with the larger radius has an oblong hole extending in the circumferential direction of the part. A shaft can be placed through the oblong hole from the femur into the tibia. In addition, a tibia cap can be fitted onto the plateau of the tibia.

摘要： An implantable elbow joint for connecting the upper arm and the forearm includes an axially extending sleeve of C-shape transverse cross-section, a cylindrical member engageable within the sleeve, and a connecting member implantable in the ulna and engageable with the cylindrical member in the sleeve. The sleeve embraces the trochlea of the humerus through an angle of more than 180.degree. about the sleeve axis and also serves as the abutment for supporting the radius. The sleeve has a slot extending in the radial and the circumferential directions. At least in the region of the slot, the internal surface of the sleeve is formed by a cylindrically shaped surface. A cylindrically shaped sliding member is supported in the sleeve in the region of the slot. An elongated shaft is arranged to be inserted into the ulna with one end projecting out of the ulna and extending through the slot into the sliding member.
摘要翻译： 用于连接上臂和前臂的可植入肘关节包括C形横截面的轴向延伸的套筒，可接合在套筒内的圆柱形构件和可移植到尺尺中并可与圆柱形构件接合的连接构件 袖。 袖子围绕套筒轴围绕肱骨的滑车角度大于180°，并且还用作支撑半径的基台。 套筒具有沿径向和圆周方向延伸的槽。 至少在槽的区域中，套筒的内表面由圆柱形表面形成。 圆筒形的滑动构件在狭槽的区域中被支撑在套筒中。 细长轴被布置成插入尺尺中，一端突出尺尺并延伸穿过狭槽进入滑动构件。
