Hip prosthesis for use in orthopedic implants field, has rod having general axis making angle that includes specific value by projection of frontal plane, and neck with length measured between end opposite to rod and base

摘要

The prosthesis has a rod (1) having a general axis (A-A') making an angle (alpha) with an axis (B-B') of a neck (2). The angle has, by projection in a frontal plane, a specific value, in which alpha equals 0.1376L + 108.3648 +- e, in which L is the length of the rod and e is a tolerance of 0.09 degree. The neck has a length (lc), measured between the end opposite to the rod and a base for connecting the neck and the rod, which is expressed by equation, in which lc equals 0.248 L -1.5 +- e', in which e' has tolerance of 0.25mm. An independent claim is also included for an assembly of hip prosthesis.
