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. (FIG. 1).
Claims17
A hip joint prosthesis comprising an elongated stem, a neck and a head, said prosthesis extending between a proximal end and a distal end and having a lateral side, a medial side, a ventral side and a dorsal side, said stem being configured to be implanted in a medullary cavity of a femur, said stem being hollow over at least a substantial fraction of the length of the stem, said hollow stem having a horseshoe-shaped cross-section with a medial wall portion, a dorsal wall portion and a ventral wall portion, wherein the cross-section is open at said lateral side of said prosthesis.
