However, clinical reports on carbon intramedullary nails are still limited, and there are few reports on postoperative complications. The present case report describes a 55-year-old female patient who sustained an unstable intertrochanteric fracture of the left femur and underwent open reduction and internal fixation using a CFR-PEEK intramedullary nail. Ultimately, within just 6\u00a0months after the initial surgery, varus deformity developed at the fracture site, resulting in failure of the junction between the intramedullary nail and the lag screw, and necessitating revision surgery involving total hip arthroplasty.<\/jats:p>","DOI":"10.1093\/jscr\/rjag758","type":"journal-article","created":{"date-parts":[[2026,8,15]],"date-time":"2026-08-15T12:47:56Z","timestamp":1786798076000},"source":"Crossref","is-referenced-by-count":0,"title":["Case of implant failure following osteosynthesis for an intertrochanteric femoral fracture using a carbon fiber intramedullary nail"],"prefix":"10.1093","volume":"2026","author":[{"given":"Taisei","family":"Suzuki","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Takarazuka City Hospital , 4-5-1 Kohama-cho, Takarazuka City 665-0827, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeo","family":"Fukunishi","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Nishinomiya Kaisei Hospital , 1-4, Ohama-cho, Nishinomiya City 662-0957, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shohei","family":"Okahisa","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Goshi Hospital , 1-8-20, Nagasunishidoori, Amagasaki City 660-0807, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saori","family":"Niitsu","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Goshi Hospital , 1-8-20, Nagasunishidoori, Amagasaki City 660-0807, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syuya","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Nishinomiya Kaisei Hospital , 1-4, Ohama-cho, Nishinomiya City 662-0957, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiya","family":"Tachibana","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Hyogo Medical University Hospital , 1-1, Mukogawa-cho, Nishinomiya City 663-8501, Hyogo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,2]]},"reference":[{"key":"2026090214054676400_ref1","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1186\/1471-2474-11-133","article-title":"3066 consecutive gamma nails: 12 years experience at a single Centre","volume":"11","author":"Bojan","year":"2010","journal-title":"BMC Musculoskelet Disord"},{"key":"2026090214054676400_ref2","first-page":"23","article-title":"Type II intertrochanteric fractures: proximal femoral nailing (PFN) versus dynamic hip screw (DHS)","volume":"4","author":"Jonnes","year":"2016","journal-title":"Arch Bone Jt Surg"},{"key":"2026090214054676400_ref3","doi-asserted-by":"publisher","first-page":"42","DOI":"10.1186\/s10195-023-00724-4","article-title":"Carbon-fibre plates for traumatic and (impending) pathological fracture fixation: where do we stand?
