    摘要: The present invention provides a highly polished femoral implant (1) having a proximal neck portion (10), a distal tip portion (30), and an elongate stem portion (20) that extends from the neck portion to the tip portion. The stem portion (20) has a proximal or metaphyseal end region (21) which adjoins the neck portion (10), the proximal/metaphyseal end region (21) having a profile in the medio-lateral plane defined by a curved or angled medial outer contour and a curved or straight lateral outer contour. The stem portion (20) of the implant has a first part (24) adjacent said end region (21) having a profile in the medio-lateral plane which tapers distally at a first angle of taper to a region intermediate the length of the stem portion, and a second part (25,26) distal of the first part (24) having a profile in the medio-lateral plane which tapers distally at a second angle of taper from the region intermediate the length of the stem portion.

    摘要: The figures show a cementable shaft prosthesis (1) comprising a centering apparatus (2) of plastic which can be pushed on at its distal shaft end (3) and which forms a cavity (4) to the distal shaft end (3). Between the distal shaft end (3) and the centering apparatus (2) there exists a clamping connection which enables a deeper sinking in of the shaft end into the cavity in the distal direction. The clamping connection is achieved by a spigot (7) which is formed on at the centering apparatus (2) in the cavity (4) and which protrudes in into a conical bore (5) of the shaft end (3) in the proximal direction.
