[A new technique for socket implantation into dysplastic acetabula (author's transl)].

This report presents a new technique of socket implantation into the dysplastic acetabulum. A major part of the resected femoral head serves as the so-called intra acetabular femoral head graft and is screwed into the lateral part of the original acetabulum. By this technique it is possible to achieve a complete bony reconstruction of the dysplastic acetabulum into which a square shaped small ceramic socket can be easily implanted using few especially designed instruments. After the description of the operative technique this report presents the clinical results of this procedure based on 11 personal cases. Finally the technical, biomechanical and biological advantages of this implantation technique are discussed in view of other similar methods described recently.
