A rare complication is the distal migration of the rod\u2019s proximal female component, which complicates standard revision surgery. This article aims to describe a surgical technique for the revision of a distally migrated Fassier\u2013Duval (FD) femoral rod. Methods: We present the case of an 8-year-old girl with OI type IV who experienced distal migration of her right femoral FD rod\u2014the surgical technique involved extracting the rod retrogradely through the fracture\/osteotomy site. We used a trephine to remove surrounding bone within the canal, thereby preserving the critical bone stock in the greater trochanter needed for secure fixation of the revision implant. Results: The distally migrated female component was successfully removed through the trephined canal with a combination of axial traction and rotational force. The proximal bone stock was preserved, allowing for the stable placement of a revision FD rod. Conclusions: The retrograde trephine technique is a viable and effective strategy for revising a distally migrated telescoping rod in patients with OI. This approach prioritizes the preservation of proximal bone stock, which is crucial for the stability and longevity of the revision implant.<\/jats:p>","DOI":"10.3390\/children12091269","type":"journal-article","created":{"date-parts":[[2025,9,22]],"date-time":"2025-09-22T08:37:39Z","timestamp":1758530259000},"page":"1269","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Surgical Technique for Revision of the Distally Migrated Fassier\u2013Duval Femoral Rod in Osteogenesis Imperfecta: A Case Report"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0594-8373","authenticated-orcid":false,"given":"Peter","family":"Staunton","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, University of Limerick Hospitals Group, V94 T9PX Limerick, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0346-7135","authenticated-orcid":false,"given":"Pasin","family":"Tangadulrat","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Faculty of Medicine, Prince of Songkla University, Songkhla 90110, Thailand"},{"name":"Pediatrics and Limb Deformity Unit, Department of Pediatric Orthopaedic Surgery, Shriners Hospital for Children, McGill University, Montreal, QC H4A 0A9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0664-2843","authenticated-orcid":false,"given":"Reggie Charles","family":"Hamdy","sequence":"additional","affiliation":[{"name":"Pediatrics and Limb Deformity Unit, Department of Pediatric Orthopaedic Surgery, Shriners Hospital for Children, McGill University, Montreal, QC H4A 0A9, Canada"},{"name":"Division of Pediatric Orthopaedic Surgery, Montreal Children\u2019s Hospital, Montreal, QC H4A 3H9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"264","DOI":"10.1007\/s11914-021-00665-z","article-title":"Osteogenesis Imperfecta-Who Needs Rodding Surgery?","volume":"19","author":"Fassier","year":"2021","journal-title":"Curr.
