Of 146 dysplastic hips treated by THR and a shelf graft, 43 were revised at an average of 156 months, 34 of which were suitable for this study (seven hips were excluded because of insufficient bone-stock data and two hips were excluded because allograft was used in the primary THR). The acetabular bone stock of the hips was assessed during revision surgery. The mean implant\u2013bone contact was 58% (50% to 70%) at primary THR and 78% (40% to 100%) at the time of the revision, which was a significant improvement (p &lt; 0.001). At primary THR all hips had had a segmental acetabular defect &gt; 30%, whereas only five (15%) had significant segmental bone defects requiring structural support at the time of revision. In 15 hips (44%) no bone graft or metal augments were used during revision. <\/jats:p><jats:p> A total of 30 hips were eligible for the survival study. At a mean follow-up of 103 months (27 to 228), two aseptic and two septic failures had occurred. Kaplan-Meier survival analysis of the revision procedures demonstrated a ten-year survival rate of 93.3% (95% confidence interval (CI) 78 to 107) with clinical or radiological failure as the endpoint. The mean Oxford hip score was 38.7 (26 to 46) for non-revised cases at final follow-up. <\/jats:p><jats:p> Our results indicate that the use of shelf autografts during THR for dysplastic hips restores bone stock, contributing to the favourable survival of the revision arthroplasty should the primary procedure fail. <\/jats:p><jats:p> Cite this article: Bone Joint J 2013;95-B:777\u201381. <\/jats:p>","DOI":"10.1302\/0301-620x.95b6.31346","type":"journal-article","created":{"date-parts":[[2013,5,30]],"date-time":"2013-05-30T08:42:50Z","timestamp":1369903370000},"page":"777-781","update-policy":"http:\/\/dx.doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Revision of the acetabular component in dysplastic hips previously reconstructed with a shelf autograft"],"prefix":"10.1302","volume":"95-B","author":[{"given":"M.","family":"Abolghasemian","sequence":"first","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Drexler","sequence":"additional","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Abdelbary","sequence":"additional","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Sayedi","sequence":"additional","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Backstein","sequence":"additional","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Kuzyk","sequence":"additional","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O.","family":"Safir","sequence":"additional","affiliation":[{"name":"Mount Sinai Hospital, University\rof Toronto, 600 University Street, Suite\r476 (A), Toronto, Ontario, M5G\r1X5, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.
