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.
An elongate, integrally formed prosthetic bone implant having a distal tip portion, a proximal neck portion and an elongate stem portion extending from the neck portion to the tip portion, wherein the stem portion of the implant has a first part adjacent the proximal neck portion having a profile in one of the medio-lateral and sagittal planes which tapers distally to a region intermediate the length of the stem portion at a first angle of taper, and a second part distal of the first part having a profile in that same one of the medio-lateral and sagittal planes which tapers distally from the region intermediate the length of the stem portion at a second angle of taper.
