ABSTRACT:
The invention relates to a single-part, biocompatible hip-joint socket moorable without cement, which hip-joint socket can be used universally in combination with hip-joint endoprostheses and is especially suitable for the treatment of dysphasia hips. The joint socket is made of Ti or Ta metals forming a barrier layer or of alloys thereof and is provided with a perforated flange ring for screwing to the pelvic bone, as well as being provided over its entire surface with specific function characteristic oxide layers containing bioactivators. For the implantation of the hip-joint socket, there are not required any special operating instructions, and additional operations, such as pelvic osteotomies, plasties of the roof of the acetabulum and repeated operations are prevented or minimized.
