Extensile anterior column acetabular reconstruction in revision total hip arthroplasty.

The extensile triradiate approach, with anterior-column plate reconstruction using structural allografts, was used in 12 cases. Pelvic discontinuity requiring posterior-plate application was present in eight of these cases. Allograft reconstructions seemed to be radiographically incorporated by approximately 8 months postoperatively and all discontinuities united. The results were excellent in four cases, good in two cases, fair in three cases, and poor in three cases. Two cups were revised for loosening. Deep sepsis resulted in graft and component removal in two cases. At reexploration, discontinuity and allografts were noted to be healed in these cases.
