ABSTRACT:
The invention relates to a hip joint prosthesis and its use in hip joint surgery. Essentially, the construction of the prosthesis is a laterally open hollow body whose cross-section (31) is horseshoe-shaped. This allows ideal adaption to the lines of load transfer. It is preferable for the prosthesis to comprise a laterally open hollow body as the stem (3), a more solid neck portion (2) and a head (1), which can be multidimensionally adjusted on the neck portion. The prosthesis can also be a complete implant with the construction of a straight-stemmed prosthesis having S-shaped mass distribution.
