ROLE AND RESULTS OF THE HIGH HIP CENTER

Anatomic placement of the acetabular component should be the surgeon's goal at the time of revision THA. However, Acetabular loosening with subsequent implant migration, progressive superior acetabular bone des truction or severe pelvic osteolysis, may prevent the surgeon from obt aining adequate host bone-implant contact needed for a successful reco nstruction while maintaining a normal hip center. The high hip center offers a technique for reconstruction of an acetabulum with severe bon y deficiency and where the majority of the remaining host bone is supe rior to the anatomic hip centre.
