Monoblock unipolar hemiarthroplasty implanted in a 39-year-old man, revised for a) deep acetabular wear and stem breakage with b) cementless impaction bone grafting, revision acetabular implant and conic stem. c) Eight years later, we can appreciate the union of the graft and the perfect reconstruction of the medial wall. d) When a second revision was needed, the bone stock of the socket was so reconstituted that the surgeon could implant a simple hemispherical cup with screws.
