Imaging revealed bilateral osteonecrosis with severe central collapse and lateral extrusion of the left femoral head. He underwent staged hip preservation: examination under anesthesia, adductor tenotomy, femoral head elevation with trephine decompression and cancellous autograft and allograft, followed by femoral varus osteotomy (FVO) and anterior osteochondroplasty. At the 2-year follow-up, pain, gait, mobility, and hip motion markedly improved with maintained femoral head containment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Femoral head elevation combined with FVO may improve symptoms and delay arthroplasty in advanced pediatric SCD hip osteonecrosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.25.00650","type":"journal-article","created":{"date-parts":[[2026,3,12]],"date-time":"2026-03-12T18:00:28Z","timestamp":1773338428000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Hip Osteonecrosis in Sickle Cell Disease Patient With Severe Central Head Collapse Treated With Staged Hip Preservation"],"prefix":"10.2106","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7774-7714","authenticated-orcid":false,"given":"Jonathan D.","family":"Grabau","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8237-6684","authenticated-orcid":false,"given":"Jessica A.","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0330-4777","authenticated-orcid":false,"given":"Harry K.
