Abstract
A new method to reconstruct major acetabular floor defects is described. It relies on the placement of special nails into each of the three bones of the hemipelvis. Curved lugs attached to the nails are coalesced using bone cement forming a platform onto which a standard acetabular prosthesis is located. Forty-seven cases are reported with a mean follow-up of 4.4 years (1 to 8). No loosening of an acetabular cup or migration of the device has occurred.
