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 destruction or severe pelvic osteolysis, may prevent the surgeon from obtaining adequate host bone-implant contact needed for a successful reconstruction while maintaining a normal hip center. The high hip center offers a technique for reconstruction of an acetabulum with severe bony deficiency and where the majority of the remaining host bone is superior to the anatomic hip centre.
