Total hip arthroplasty (THA) in this setting typically requires corrective osteotomy and bone grafting. A simplified, osteotomy-free strategy has not been well characterised.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 50-year-old woman with monostotic FD and moderate shepherd's crook deformity (neck-shaft angle 110\u00b0) underwent primary THA via the direct anterior approach using a fully hydroxyapatite-coated cementless revision stem, without corrective osteotomy or bone grafting. Intraoperative blood loss was 200\u2005mL. Full weight-bearing was achieved on postoperative day one. At six months, the Harris Hip Score improved from 64 preoperatively to 90, and radiographs confirmed stable implant fixation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In selected patients with monostotic FD, neck-shaft angle \u2265110\u00b0, and adequate distal bone stock, this simplified approach permits immediate weight-bearing and excellent early function.
